In addition, the passage of the second entrance 67 is not limited to 4 times as in the case of the 1st entrance 64, and is not limited to 4 times, or 3 times or less (for example, (8 times). Further, since the number of times of holding is indicated by the first symbol display device 37, the lighting display by the holding lamp 84 may not be performed.

  Below the variable display device unit 80, a first entrance 64 into which a sphere can enter is disposed. When a ball enters the first entrance 64, a first entrance switch (not shown) provided on the back side of the game board 13 is turned on, and the first entrance switch is turned on. The main controller 110 performs a lottery lottery, and a display corresponding to the lottery result is indicated by the LED 37 a of the first symbol display device 37.

In the pachinko machine 10, when the lottery in the main controller 110 is a big hit, after a predetermined time (fluctuation time) has elapsed, the LED 37a of the first symbol display device 37 is turned on so as to become a big hit stop symbol. The stop symbol corresponding to the jackpot is displayed on the third symbol display device 81 to indicate the occurrence of the jackpot. Thereafter, the gaming state transitions to a special gaming state (big hit) where the ball is easy to win. In this special gaming state, the special winning opening 65a that is normally closed is opened for a predetermined time (for example, until 30 seconds have elapsed or ten balls have been won).

  The specific winning opening 65a is closed when a predetermined time elapses, and after the closing, the specific winning opening 65a is opened again for a predetermined time. The opening / closing operation of the specific winning opening 65a can be repeated up to 16 times (16 rounds), for example. The state in which the opening / closing operation is performed is a form of a special gaming state advantageous to the player, and the player is given out a larger amount of prize balls than usual in order to give a gaming value (game value). Is done.

  Specifically, the variable winning device 65 includes a horizontally-long rectangular opening / closing plate that covers the specific winning opening 65a, and a solenoid for opening / closing driving the lower side of the opening / closing plate as an axis. The special winning opening 65a is normally closed so that a ball cannot be won or difficult to win. In the case of a big hit, the solenoid is driven to tilt the opening / closing plate downward and the ball temporarily forms an open state in which the ball is likely to win the specific winning opening 65a. Operates to alternate states.

  Note that the special gaming state is not limited to the above-described form. When the game area is provided with a large opening that is opened and closed separately from the specific winning opening 65a, and the LED 37a corresponding to the jackpot is turned on in the first symbol display device 37, the specific winning opening 65a is opened for a predetermined time, and the specific winning opening A special gaming state is defined as a game state in which a large opening provided separately from the specific winning port 65a is opened for a predetermined time and a predetermined number of times when the ball 65 is opened into the specific winning port 65a.

Consolidated). In addition, a seal (not shown) is attached to the connecting portion between the box base and the box cover over the box base and the box cover. This seal seal is made of a brittle material. If the seal is to be peeled off in order to open the substrate boxes 100, 102, or if the substrate boxes 100, 102 are forcibly opened, the box base side and the box cover are removed. Cut to the side. Therefore, it is possible to know whether or not the substrate boxes 100 and 102 have been opened by checking the sealing unit or the sealing seal.

  The payout unit 93 includes a tank 130 that is located at the top of the back pack unit 94 and opens upward, a tank rail 131 that is connected to the lower side of the tank 130 and is gently inclined toward the downstream side, and downstream of the tank rail 131. A case rail 132 that is vertically connected to the side, and a payout device 133 that is provided at the most downstream portion of the case rail 132 and that pays out a ball with a predetermined electrical configuration of the payout motor 216 (see FIG. 8). ing. The tank 130 is successively replenished with balls supplied from the island equipment of the game hall, and a required number of balls are paid out by the payout device 133 as appropriate.

  Next, the inside of the substrate box 101 will be described with reference to FIG. The board box 101 is for maintaining and protecting the inside of the display control device 114. FIG. 4 shows the internal structure of the substrate box 101.

  The board box 101 includes a display control device 114 that controls display contents, a shield unit 151 that blocks electromagnetic noise radiated from the display control device 114, and a display control device 114. Between the 3rd symbol display device 81 which displays the controlled contents, the front panel 142 which fixes the 3rd symbol display device 81, the 3rd symbol display device 81 which is fixed to the display control device 114 and the front panel 142 A transparent rear case 140 is provided in which the display controller 114, the shield 151, the substrate holder 141, and the third symbol display device 81 are accommodated with the front panel 142 as a lid. And.

  The substrate holder 141 is formed of a transparent non-conductive resin material, and also functions as a buffer material that prevents the display control device 114 and the third symbol display device 81 from coming into contact with each other. The rear case 140 has a plurality of holes 143 and 144, and air in the substrate box 101 is circulated through the holes 143 and 144. In particular, a hole 144 is formed in a portion facing a position where a cooling fan 152 described later is disposed. The hole 144 is formed in an annular shape corresponding to the shape of the fan portion of the cooling fan 152.

  Here, the shield part 151 will be described with reference to FIG. In FIG. 5, only the MPU 231 and the image controller 236 as the image processing IC among the components mounted (mounted) on the display control device 114 are illustrated, and the other components are not illustrated.

  The shield 151 is for blocking electromagnetic noise and suppressing heat generation of the display control device 114 so as not to cause malfunction of other control devices due to electromagnetic noise from the display control device 114. The shield unit 151 disposed on the display control device 114 has an adhesiveness that is affixed to the MPU 231 mounted on the display control device 114, the image controller 236 as an image processing IC, and the upper surfaces of the MPU 231 and the image controller 236. A non-conductive and thermally conductive silicone rubber sheet 157; and a heat sink 156 having conductivity and thermal conductivity for contacting the silicone rubber sheet 157 and radiating heat conducted from the MPU 231 and the image controller 236 to the space. , Fixed by a heat sink 156 and a conductive screw 161, for fixing formed of a metal sheet metal having conductivity and heat conductivity for blocking electromagnetic noise radiated from the MPU 231, the image controller 236, and the display control device 114 Sheet metal 153 and the upper surface of fixing sheet metal 153 are drilled, The top hole 163 that promotes the circulation of air and improves the visibility inside the fixing sheet metal 153 and the side holes of the fixing sheet metal 153 are perforated to promote the circulation of air and improve the visibility inside the fixing sheet metal 153. A hole 164 to be improved, and a grounding tool 154 that is formed in a part of the lower end of the fixing metal plate 153, is in contact with the ground surface of the display control device 114 and the conductive screw 162, and is also electrically connected; An adjustment unit 155 that is formed at a part of the lower end of the fixing sheet metal 153, is in contact with the ground plane of the display control device 114, is electrically connected, and further adjusts the distance from the grounding tool 154, and fixing An air cooling fan 152 that is fixed by a sheet metal 153 and a conductive screw 160 and forcibly generates air circulation is configured. The tip of the adjustment unit 155 penetrates from the hole 159 formed in the display control device 114 to the back surface of the display control device 114.

  The fixing sheet metal 153 and the heat sink 156 constitute a shield member. Further, the fixing sheet metal 153 may be configured without forming the top hole 163 and the hole 164. In addition to the grounding tool 154 and the adjusting unit 155, the fixing sheet metal 153 holds the shield unit 151 attached to the upper surface of the display control device 114 without being connected to the ground surface of the display control device 114. You may provide the auxiliary | assistant part which assists. Although the shape of the auxiliary portion is substantially the same as that of the adjustment portion 155, the tip thereof is formed shorter than the adjustment portion 155 and is supported on the upper surface of the display control device 114. That is, the adjustment unit 155 penetrates the back surface of the display control device 114 through the hole 159, but the auxiliary unit is supported on the upper surface of the display control device 114.

  FIG. 6 shows a cross-sectional view when the components shown in FIG. 5 are assembled. A silicone rubber sheet 157 is overlaid on the MPU 231 and the image controller 236 mounted on the display control device 114, and a heat sink 156 is overlaid on the silicone rubber sheet 157. The heat sink 156 is fixed to the fixing metal plate 153 by the conductive screw 161, and the grounding tool 154 of the fixing metal plate 153 is fixed to the ground surface of the display control device 114 by the conductive screw 162. An air cooling fan 152 is fixed to the fixing sheet metal 153 with a conductive screw 160. With this structure, the air cooling fan 152, the fixing metal plate 153, and the heat sink 156 are electrically connected to the ground plane of the display control device 114. Therefore, the air cooling fan 152, the fixing metal plate 153, and the heat sink 156 exhibit a function of blocking electromagnetic noise. Thereby, the electromagnetic noise radiated | emitted from the display control apparatus 114 can be interrupted | blocked. Therefore, malfunction of other circuit boards due to electromagnetic noise radiated from the display control device 114 can be prevented. Further, even if electromagnetic noise is generated by the air cooling fan 152, this electromagnetic noise can also be blocked. Furthermore, since there is an appropriate space between the fixing sheet metal 153 and the display control device 114, air circulation inside the fixing sheet metal 153 is facilitated as compared with the case where there is no such space.

  The silicone rubber sheet 157 attached on the MPU 231 and the image controller 236 is attached by the adhesiveness of silicone without using an adhesive or the like. Therefore, the markings printed on the MPU 231 and the image controller 236 can be easily confirmed by easily peeling them off from the upper surfaces of the MPU 231 and the image controller 236, respectively. Similarly, since the shield member constituted by the fixing metal plate 153 and the heat sink 156 is also fixed to the ground surface of the display control device 114 by the conductive screw 162, the shield member can be removed by removing the conductive screw 162. Can be easily removed and the inside can be checked.

  FIG. 7 shows a perspective view when the components shown in FIG. 5 are assembled. Here, except for the portion where the grounding tool 154 and the adjusting tool 155 are formed, the lower end of the fixing sheet metal 153 is disposed with a distance d from the display control device 114. Further, the grounding tools 154 are arranged at a distance a, the grounding tool 154 and the adjusting tool 155 are arranged at a distance b, and the adjusting tools 155 are arranged at a distance c. Further, the top hole 163 and the hole 164 are formed in a circular shape having a diameter e. The distances a, b, c, the distance d, and the diameter e are all set to less than half of the shortest wavelength of electromagnetic noise to be cut off. This is because the space composed of the distances a, b, c, the distance d, and the diameter e exhibits a function as a slot antenna in which a metal plate is cut and this cut is used as an antenna as a radiating element.

  For example, when looking at the physical phenomenon in the space portion of the distance a, when the electric field becomes zero at both ends of the space distance a, it is assumed that it is half of the shortest wavelength of electromagnetic noise that blocks the distance a. This is because the electric field of electromagnetic noise having the shortest wavelength to be cut off generates a standing wave, and the space portion of the distance a resonates. Similar physical phenomena occur with respect to the distances b and c, the distance d, and the diameter e. For this reason, the distances a, b, c, the interval d, and the diameter e are all set to be less than one half of the shortest wavelength of the electromagnetic noise to be cut off. , C, interval d, and diameter e cannot resonate. Therefore, compared to the case where the distance a, b, c, the distance d, and the diameter e are all set to be half or more of the shortest wavelength of electromagnetic noise, the amount of electromagnetic noise radiated from these spaces. Can be suppressed.

  Therefore, except for the portion where the grounding tool 154 and the adjusting tool 155 at the lower end of the fixing metal plate 153 are formed, the display control device 114 and the grounding tool 154 are separated from each other by a distance a. The grounding tool 154 and the adjusting tool 155 are arranged at a distance b, the adjusting tools 155 are arranged at a distance c, and the top hole 163 and the hole 164 are formed by a circle having a diameter e. Radiation of electromagnetic noise can be suppressed.

The shortest wavelength of electromagnetic noise to be blocked will be described. In the present embodiment, the operation clock between the MPU 231 and the image controller 236 of the display control device 114 is 100 to 200 MHz. For example, when the wavelength of 100 times the frequency is the shortest wavelength of electromagnetic noise to be cut off, the following is obtained. That is, since (wavelength λ) = (light speed c) ÷ (frequency to be cut off), when cutting off a frequency 100 times 200 MHz (that is, 200 MHz × 100 = 20 GHz), the light speed c = 3 × 10 ⁸ meters / second. Therefore, the wavelength λ = 3 × 10 ⁸ ÷ 20 × 10 ⁹ meters = 15 millimeters. Since the distances a, b, c, the distance d, and the diameter e are all set to less than one half of the shortest wavelength of electromagnetic noise to be cut off, in the present embodiment, 15 millimeters ÷ 2 = less than 7.5 millimeters. .

  In the above description, the wavelength λ having a frequency 100 times the operation clock is the shortest wavelength of electromagnetic noise to be cut off. However, the present invention is not necessarily limited to this, and depending on the characteristics of the circuit board and the gaming machine, the wavelength λ having a frequency 500 to 1000 times or more or less than the operation clock is set as the shortest wavelength of electromagnetic noise to be cut off. , Distances a, b, c, interval d, and diameter e may be set.

  In the present embodiment, the operation clock of the MPU 201 of the main control device 110 is 8 MHz, and the operation clocks of the MPUs 212 and 221 of the payout control device 111 and the sound lamp control device 113 are 20 MHz. For this, the shortest wavelength of electromagnetic noise to be cut off is calculated according to each circuit board, and the distances a, b, c, the distance d, and the diameter e are set.

  In the above description, the distances a, b, c, the distance d, and the diameter e are all set to be less than one half of the shortest wavelength of electromagnetic noise to be blocked. Alternatively, any one parameter of the diameter e may be selected and cut off to be less than a half of the shortest wavelength of electromagnetic noise. In this case, the selected parameters among the distances a, b, c, the distance d, and the diameter e are radiated from these spaces as compared with the case where the selected parameter is set to one half or more of the shortest wavelength of electromagnetic noise to be cut off. The amount of electromagnetic noise radiation can be suppressed.

  Next, even if the air cooling fan 152 forcibly generates the air circulation of the fixing sheet metal 153, there is a gap due to the spaces of distances a, b, c, the interval d, and the diameter e, so that the air circulation is delayed. Therefore, the air is smoothly circulated between the inside and the outside of the fixing metal plate 153. Therefore, even if the display control device 114 is covered with the fixing metal plate 153, the display control device 114 inside the fixing metal plate 153 can be forcibly cooled by the air circulation by the air cooling fan 152, and the heat of the elements of the display control device 114 can be obtained. It becomes possible to suppress runaway. In addition, since the air cooling fan 152 is used, air circulation can be locally generated even on the display control device 114 in the heat sink 156 portion that particularly requires cooling. Therefore, the cooling effect can be enhanced as compared with the case where the air on the display control device 114 is circulated uniformly.

  Further, since the grounding tool 154 and the adjusting tool 155 at the lower end of the fixing sheet metal 153 are arranged apart from the display control device 114 by a predetermined distance d, the grounding tool 154 and the adjusting tool are arranged. Wiring 165 and the like can be formed on the substrate portion on the display control device 114 other than the portion where the terminal 155 is in contact with the ground plane of the display control device 114. Therefore, the substrate can be effectively used as compared with the case where the entire lower end of the fixing sheet metal 153 is brought into contact with the substrate.

  In addition, the display control device 114 is covered with the fixing metal plate 153. For this reason, the electromagnetic noise radiated | emitted from the part which radiates | emits electromagnetic noise can be interrupted | blocked by covering the part which radiates | emits electromagnetic noise which is the whole or a part of the display control apparatus 114 with a shield member. Therefore, it is possible to prevent malfunctions caused by electromagnetic noise emitted from other elements mounted on the same display control device 114 that are not covered by the shield member, while preventing malfunction due to electromagnetic noise of the main controller 110. .

  Further, since it is not necessary to cover main controller 110 with fixing sheet metal 153, MPU 202 mounted on main controller 110 can be visually observed. Therefore, it is possible to solve the problem that the MPU 202 mounted on the main control device 110 cannot be seen, which may occur when the main control device 110 is covered with the fixing sheet metal 153. Furthermore, since the MPU 202 mounted on the main control device 110 can be visually checked, it is possible to detect unauthorized exchange of the main control device 110.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. FIG. 8 is a block diagram showing an electrical configuration of the pachinko machine 10.

  The main controller 110 is equipped with an MPU 201 as a one-chip microcomputer that is an arithmetic unit. The MPU 201 includes a ROM 202 that stores various control programs executed by the MPU 201 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 202 is executed. A certain RAM 203 and various other circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated. Various commands are sent from the main control device 110 to the sub control device by the data transmission / reception circuit in order to instruct the operation to a peripheral control device (sub control device) such as the payout control device 111 or the sound lamp control device 113. However, such a command is transmitted from the main controller 110 to the sub controller only in one direction.

  The RAM 203 stores the contents of the internal registers of the MPU 201, the return address of the control program executed by the MPU 201, and the work area (work area for storing various flags and counters, I / O values, etc. Area). The RAM 203 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 115 even after the power of the pachinko machine 10 is shut off, and all data stored in the RAM 203 is backed up.

  An input / output port 205 is connected to the MPU 201 of the main control device 110 via a bus line 204 composed of an address bus and a data bus. The input / output port 205 is connected to the payout control device 111 via the connectors 207 and 217 and the sound lamp control device 113 via the connectors 208 and 228, respectively. In addition, the input / output port 205 is connected to various switches 206 including a first symbol display device 37, a second symbol display device 82, an external output terminal plate 261, a switch group and a sensor group not shown. A hall computer 262 can be connected to the external output terminal plate 261, and data or the like can be output from the main controller 110 to the hall computer 262 via the external output terminal plate 261.

  The payout control device 111 drives the payout motor 216 to perform payout control of prize balls and rental balls. The MPU 211 as an arithmetic unit includes a ROM 212 that stores a control program executed by the MPU 211, fixed value data, and the like, and a RAM 213 that is used as a work memory or the like.

  The RAM 213 of the payout control device 111, like the RAM 203 of the main control device 110, has a stack area for storing the contents of the internal registers of the MPU 211, the return address of the control program executed by the MPU 211, and various flags and counters. And a work area (work area) in which values such as I / O are stored. The RAM 213 is configured to be able to retain (backup) data by being supplied with a backup voltage from the power supply device 115 even after the power of the pachinko machine 10 is cut off, and all data stored in the RAM 213 is backed up.

  In the work area of the RAM 213, a total prize ball number memory 213a, an upper command storage buffer 213b, a payout error flag 213c, and a payout permission flag 213d are provided.

  The total prize ball number memory 213a is a memory for storing the total number of unpaid prize balls to be paid out by the payout control device 111. A ball that has been driven into the game area wins one of the winning holes 63, 64, 65a, and when this is detected by the main control device 110, a payout of the number of prize balls according to the winning is a prize ball command. (See FIG. 11), the main controller 110 instructs the payout controller 111. In the total prize ball number memory 213a, the number of payout of prize balls designated by the prize ball command is added and stored. If the value of the total prize ball number memory 213a is not 0, the prize ball is paid out, and the value is decremented by 1 every time one prize ball is detected. The payout of prize balls is performed until the value of the total prize ball number memory 213a becomes zero.

  The upper command storage buffer 213b is a buffer for storing an upper command (first byte command) among the 2-byte commands output from the main control device 110 to the payout control device 111 shown in FIG. The main controller 110 outputs a payout return command, a payout initialization command, and 15 types of prize ball commands to the payout control device 111. These upper commands (99H) are output to the upper command storage buffer 213b. , AAH, F0H to FEH) are stored. The contents of the upper command storage buffer 213b are cleared to 0 when a lower command (second byte command) is input.

  The payout error flag 213c is a flag that is turned on when the payout control device 111 cannot normally input the 2-byte command output from the main control device 110 to the payout control device 111 shown in FIG. When the payout error flag 213c is turned on, a character “C” is displayed on the 7-segment LED 121 by the state notification process (S906 in FIGS. 21 and 25), and the occurrence of a command error is notified. The payout error flag 213c once turned on is turned off when a normal command of 2 bytes is input. When the payout error flag 213c is turned off, the error display of the 7 segment LED 121 is also canceled.

  The payout permission flag 213d is a flag for permitting the payout of the winning ball or the loaned ball, and is turned off in the start-up process (S808, S811, S812 in FIG. 20), but is normal output from the main control device 110. Is turned on when a command (such as a payout initialization command, a payout power recovery command, or a prize ball command) is input. That is, the payout permission flag 213d is a flag for confirming that the main control device 110 is up.

  An input / output port 215 is connected to the MPU 211 of the payout control device 111 via a bus line 214 composed of an address bus and a data bus.

Although not shown, the payout control device 111 is connected to a prize ball detection switch for detecting a prize ball that has been paid out. The prize ball detection switch is connected to the payout control device 111 but is not connected to the main control device 110.

  The 7-segment LED 121 is a display (display means) for notifying the state of the payout control device 111. When the payout control device 111 inputs a command output from the main control device 110, and it is determined that the command is an unspecified command (invalid command), the 7-segment LED 121 causes the character “C” to be displayed. Displayed to notify the occurrence of a command error. In addition, a hall computer 262 can be connected to the external output terminal plate 261, and data or the like can be output from the payout control device 111 to the hall computer 262 via the external output terminal plate 261. Errors generated in the payout control device 111 can also be output to the hall computer 262 via the external output terminal board 262.

  The launch control device 112 controls the ball launch unit 112a so that the launch strength of the ball according to the rotational operation amount of the operation handle 51 is obtained when the main control device 110 gives an instruction to launch a ball. The ball launching unit 112a includes a launching solenoid and an electromagnet (not shown), and the firing solenoid and the electromagnet are permitted to be driven when predetermined conditions are met. Specifically, it corresponds to the amount of rotation of the operation handle 51 on the condition that the touch sensor detects that the player is touching the operation handle 51 and the firing stop switch for stopping the firing is not operated. Then, the launch solenoid is excited, and the ball is launched with a strength corresponding to the operation amount of the operation handle 51.

  The sound lamp control device 113 outputs sound in a sound output device (such as a speaker (not shown)) 226, outputs light on and off in a lamp display device (such as the lighting units 29 to 33 and the display lamp 34), and the display control device 114. The setting of the display mode of the 3rd symbol display apparatus 81 performed etc. is controlled. The MPU 221 that is an arithmetic unit includes a ROM 222 that stores a control program executed by the MPU 221, fixed value data, and the like, and a RAM 223 that is used as a work memory or the like.

  An input / output port 225 is connected to the MPU 221 of the sound lamp control device 113 via a bus line 224 including an address bus and a data bus. The main control device 110 is connected to the input / output port 225 via connectors 208 and 228, and the display control device 114, the audio output device 226, the lamp display device 227, and the like are connected to the input / output port 225, respectively.

  The display control device 114 controls the change display of the third symbol on the third symbol display device (LCD) 81. The display control device 114 includes an MPU 231, a ROM (program ROM) 232, a work RAM 233, a video RAM 234, a character ROM 235, an image controller 236, an input port 237, an output port 238, and bus lines 239 and 240. It has. The input side of the input port 237 is connected to the output side of the sound lamp control device 113, and the output side of the input port 237 is connected to the MPU 231, ROM 232, work RAM 233, and image controller 236. A video RAM 234 and a character ROM 235 are connected to the image controller 236, and an output port 238 is connected via a bus line 240. A third symbol display device 81 is connected to the output side of the output port 238. Even if the pachinko machine 10 is a different model with different winning probability for winning the jackpot and the number of prize balls to be paid out in one jackpot, there is a model having the same specifications as the symbols displayed on the third symbol display device 81. Therefore, the display control device 114 is made into a common part to reduce the cost.

  The MPU 231 of the display control device 114 controls the display content of the third symbol display device 81 based on the symbol display command input from the sound lamp control device 113. The ROM 232 is a memory for storing various control programs executed by the MPU 231 and fixed value data. The work RAM 233 is a memory for temporarily storing work data and flags used when the MPU 231 executes various programs. The character ROM 235 is a memory that stores data for effects such as symbols (background symbols and third symbols) displayed on the third symbol display device 81. The video RAM 234 is a memory for storing effect data displayed on the third symbol display device 81, and the display content of the third symbol display device 81 is changed by rewriting the contents of the video RAM 234.

  The image controller 236 adjusts the timing of the MPU 231, the video RAM 234, and the output port 238 to intervene in reading and writing data, and reads display data stored in the video RAM 234 at a predetermined timing to read the third symbol display device 81. Is displayed. The image processing IC assists the image display processing of the MPU 231.

  The power supply device 115 includes a power supply unit 251 for supplying power to each unit of the pachinko machine 10, a power failure monitoring circuit 252 that monitors power interruption due to a power failure and the like, and a RAM erase switch circuit 253 having a RAM erase switch 123. ing. The power supply unit 251 supplies a necessary operating voltage to each of the control devices 110 to 114 through a power supply path (not shown). As its outline, the power supply unit 251 takes in a voltage of 24 volts AC supplied from the outside, a voltage of 12 volts for driving various switches, solenoids, motors, etc., a voltage of 5 volts for logic, a RAM A backup voltage or the like for backup is generated, and a necessary voltage is supplied to each of the control devices 110 to 114 using the 12 volt voltage, the 5 volt voltage, and the backup voltage.

  The power failure monitoring circuit 252 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the MPU 201 of the main control device 110 and the MPU 211 of the payout control device 111 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 252 monitors the voltage of 24 VDC, which is the maximum voltage output from the power supply unit 251, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts, Power failure signal SG1 is output to main controller 110 and payout controller 111. Based on the output of the power failure signal SG1, the main controller 110 and the payout controller 111 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 251 outputs a voltage of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Is maintained at a normal value. Therefore, the main control device 110 and the payout control device 111 can normally execute and complete the NMI interrupt process.

  The RAM erase switch circuit 253 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main controller 110 when the RAM erase switch 123 is pressed. When the RAM control signal SG2 is input when the pachinko machine 10 is turned on, the main controller 110 clears the backup data (contents of the RAM 203).

  Here, with reference to FIG. 9, the display content of the 3rd symbol display apparatus 81 is demonstrated. FIG. 9 is a diagram for explaining the display screen of the third symbol display device 81, and FIG. 9A is a diagram schematically showing the area division setting and the effective line setting of the display screen, FIG. 9B is a diagram illustrating an actual display screen.

  The third symbol is composed of ten types of main symbols with numbers from “0” to “9” and one type of sub-pattern of petal shape formed smaller than the main symbol. Each main symbol is composed of numbers from “0” to “9” on the rear symbol consisting of a wooden box, of which the main symbols with odd numbers (1, 3, 5, 7, 9) are A large number is added to almost the front of the wooden box. On the other hand, the main symbols with even numbers (0, 2, 4, 6, 8) are attached to the front of the wooden box almost fully, and attached symbols imitating characters such as furoshiki and helmets, An even number is small in green on the lower right side of the attached symbol, and is added so as to be displayed on the front side of the attached symbol.

  Further, in the pachinko machine 10 according to the present embodiment, when the lottery result by the main controller 110 is a big win, a variable display in which the same main symbols are arranged is performed, and a big hit occurs after the variable display is finished. It is configured as follows. When shifting to the high probability state (probability variation state) after the big hit, the variable display in which the main symbols (corresponding to “high probability symbols”) to which odd numbers are added is arranged is performed. On the other hand, when shifting to the low probability state after the big hit, the variable display is performed in which the main symbols to which the even numbers are added (corresponding to “low probability symbols”) are arranged. Here, the high probability state means a state in which the subsequent jackpot probability is increased as an added value after the jackpot is ended, that is, a so-called probability fluctuation (probability change). In addition, the normal state (low probability state) means a time when the probability of hitting is not probable, and a state where the jackpot probability is a normal state, that is, a state where the probability of jackpot is lower than that during the probability change.

  As shown in FIG. 9 (a), the display screen of the third symbol display device 81 is roughly divided into two vertically, and the lower 2/3 is the main display area Dm in which the third symbol is variably displayed, and the others. The upper third is a sub display area Ds for displaying a notice effect and a character.

  In the main display area Dm, three symbol rows Z1, Z2, and Z3 of left, middle, and right are displayed. In each of the symbol rows Z1 to Z3, the above-described third symbols are displayed in a prescribed order. That is, in each of the symbol rows Z1 to Z3, the main symbols are arranged in ascending or descending numerical order, and one sub symbol is arranged between the main symbols. For this reason, a total of 20 third symbols of 10 main symbols and 10 sub-designs are set in each symbol row, and each symbol row Z1 to Z3 is scrolled from top to bottom with periodicity. The display is changed. In particular, the main symbol numbers are arranged in descending order in the left symbol row Z1, and the main symbol numbers are arranged in ascending order in the middle symbol row Z2 and the right symbol row Z3.

  In the main display area Dm, the third symbols are displayed in the upper, middle, and lower three rows for each symbol row Z1 to Z3. Accordingly, the third symbol display device 81 displays a total of nine third symbols of 3 rows × 3 columns. In the main display area Dm, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set. In each game, the variable display stops in the order of the left symbol row Z1 → the right symbol row Z3 → the middle symbol row Z2, and the combination of jackpot symbols on any active line at the time of the stop (in this embodiment, A jackpot video is displayed as a jackpot if the same combination of main symbols) is arranged.

  The sub display area Ds is horizontally long above the main display area Dm, and is further equally divided into three notice areas Ds1 to Ds3 in the left-right direction. Here, the left and right notice areas Ds1 and Ds3 are normally covered with a double-open opaque door that is electrically opened and closed by a solenoid (not shown), and sometimes the solenoid is excited and the door is on the front side. It is a display area that is visible to the player when it is opened. The center notice area Ds2 is a display area that is always visible without being covered by the door.

  As shown in FIG. 9B, on the actual display screen, a total of nine main symbols and sub-designs of the third symbol are displayed in the main display area Dm. In the sub display area Ds, the left and right doors are closed, and the left and right notice areas Ds1, Ds3 are covered and the display screen cannot be visually recognized. If either one of the left and right doors or both doors are opened during the variable display, a video is displayed in the left and right notice areas Ds1 and Ds3, and it is easy for the player to change to a big hit than usual. It is suggested. In the center notice area Ds2, a predetermined character (a boy with a bee in this embodiment) usually performs a predetermined action and sometimes performs a special action different from the predetermined action or another character appears. The announcement effect is performed by putting out. The display screen of the third symbol display device 81 is divided into upper and lower display areas Dm and Ds in principle, but the third symbol and characters are displayed larger across the display areas Dm and Ds. A display effect can be performed.

  Next, a counter and the like provided in the RAM 203 of the main controller 110 will be described with reference to FIG. These counters and the like are used by the MPU 201 of the main control device 110 to perform jackpot lottery, display setting of the first symbol display device 37, lottery of display results of the second symbol display device 82, and the like.

  For the jackpot lottery or display setting of the first symbol display device 37, the first hit random number counter C1 used for the jackpot lottery, the first hit type symbol counter C2 used for the jackpot symbol selection, and the stop pattern selection counter C3, a first initial value random number counter CINI1 used for setting the initial value of the first random number counter C1, and variation type counters CS1, CS2, and CS3 used for variation pattern selection are used. The second symbol random number counter C4 is used for the lottery of the second symbol display device 82, and the second initial random number counter CINI2 is used for setting the initial value of the second random number counter C4. Each of these counters is a loop counter that adds 1 to the previous value every time it is updated and returns to 0 after reaching the maximum value.

  Each counter is updated at an interval of 4 ms, which is the execution interval of the main process (see FIG. 14), or at an interval of 2 ms, which is the execution interval of the timer interrupt process (see FIG. 17), and the updated value is set in a predetermined area of the RAM 203. Stored in the counter buffer. The RAM 203 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, the first entrance 64 is provided. The values of the first random number counter C1, the first type counter C2, and the stop pattern selection counter C3 are stored in accordance with the winning timing of the ball.

  Each counter will be described in detail. The first random number counter C1 is configured so that, for example, 1 is added in order within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the first random number counter C1 makes one round, the value of the first initial value random number counter CINI1 at that time is read as the initial value of the first random number counter C1. The first initial value random number counter CINI1 is configured as a loop counter that is updated in the same range as the first per-random number counter C1 (value = 0 to 738), and each time the timer interrupt process (see FIG. 17) is executed. It is updated once and updated repeatedly within the remaining time of the main process (see FIG. 14). The value of the first per-random number counter C1 is updated, for example, periodically (in this embodiment, once for each timer interrupt process), and the stored ball is stored in the RAM 203 at the timing when the ball wins the first entrance 64. Stored in the area. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “373, 727” There are 14 random numbers that are big hits at high probability, and the values are "59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 631, 683, 733".

  The first hit type counter C2 determines the display mode of the first symbol display device 37 at the time of the big hit. In the present embodiment, the first hit type counter C2 is incremented one by one within the range of 0 to 4, and the maximum value ( That is, it is configured to return to 0 after reaching 4). The value of the first hit type counter C2 is updated, for example, periodically (once every timer interruption process in this embodiment), and the stored ball is stored in the RAM 203 at the timing when the ball wins the first entrance 64. Stored in the area. In addition, the value of the random number that becomes a high probability state after the jackpot is “1, 2, 3”, the value of the random number that becomes the low probability state after the jackpot is “0, 4”, and two types of hits are determined. The Therefore, the display mode corresponding to the stop symbol displayed on the first symbol display device 37 is a display mode corresponding to two types of jackpots of a high probability state and a low probability state, and one type of display mode corresponding to a deviation. Any one of the three display modes is selected.

  The stop pattern selection counter C3 is, for example, incremented by 1 within a range of 0 to 238, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the stop pattern selection counter C3 selects the effect pattern displayed on the third symbol display device 81, and after reaching, the final stop symbol is shifted by one before and after the reach symbol. “Stop before and after detachment reach” (for example, a range of 0 to 8), and “Leach other than detachment before and after detachment” (for example, a range of 9 to 38) after the reach has occurred and the final stop symbol stops other than before and after the reach design. The three stop (effect) patterns are selected as “completely out” (for example, a range of 39 to 238) that does not cause reach. The value of the stop pattern selection counter C3 is updated, for example, periodically (once every timer interrupt process in this embodiment), and the reserved ball storage area of the RAM 203 at the timing when the ball wins the first entrance 64. Stored in

  Further, the stop pattern selection counter C3 is provided with a plurality of tables having different ranges of random number values from which the stop pattern is selected. This depends on whether the current state of the pachinko machine 10 is a high-probability state or a low-probability state, in which area of the holding ball storage area each random number value is stored (ie, the number of holdings), etc. This is to change the stop pattern selection ratio.

  For example, in a high probability state, a table with a wide random value range of 10 to 238 corresponding to the stop pattern of “completely out” is selected so that a jackpot is likely to occur and a reach effect is not selected more than necessary. It becomes easy to select “completely off”. In this table, “front / rear out of reach” is narrowed to 0-5, and “reach other than front / rear out of reach” is also narrowed to 6-9, making it difficult to select “rear out of front / rear out of reach” or “reach out of front / rear out of reach”. Further, if each random number value is not stored in the holding ball storage area in a low probability state, a disturbance corresponding to the stop pattern of “completely off” in order to secure the time for the ball to enter the first entrance 64. A table with a narrow numerical value range of 51 to 238 is selected, and “completely out” is difficult to select. In this table, the range of random numbers corresponding to the stop pattern of “reach other than front / rear deviation” is as wide as 9 to 50, and “reach other than front / rear deviation” is easily selected. Therefore, in the low probability state, the ball entry time to the first entrance 64 can be secured, and therefore, the variable display by the third symbol display device 81 is easily performed continuously.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented by 1 in order within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”.

  A rough display mode such as so-called normal reach, super reach, premium reach, or the like is determined by the first variation type counter CS1. Specifically, the determination of the display mode is determination of the variation time of the symbol variation. Further, the second variation type counter CS2 determines a variation time (in other words, the number of variation symbols) until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach. Based on the variation time determined by the variation type counters CS1 and CS2, the display control device 114 determines the reach type of the third symbol displayed on the third display device 81 and the detailed symbol variation mode. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by the combination of the first variation type counter CS1 and the stop symbol. The values of the variation type counters CS1 and CS2 are updated once every time a main process (see FIG. 14) described later is executed once, and are repeatedly updated within the remaining time in the main process.

  For example, the value of the variation type counter CS3 is sequentially incremented by 1 within a range of 0 to 162, and returns to 0 after reaching the maximum value (that is, 162). In the following description, CS3 is also referred to as a “third variation type counter”. The 3rd symbol display device 81 of this Embodiment performs the decorative production according to the display mode of the 1st symbol display device 37, and can slide the symbol which is changing in addition to the variation of a symbol. A notice effect such as passing a notice character for notifying the occurrence of the reach effect is performed. The effect pattern of the notice effect is selected by the variation type counter CS3. Specifically, the time required for the notice effect is added to the variable time, or on the contrary, the variable time is subtracted to shorten the variable display time, or an effect pattern that does not add or subtract the variable time is selected. . As with the stop pattern selection counter C3, the variation type counter CS3 is provided with a plurality of tables with different ranges of random values from which the production pattern is selected, and whether the current state of the pachinko machine 10 is in a high probability state Depending on the low probability state or in which area of the reserved ball storage area each random value is stored, the selection ratio of each effect pattern is different.

  As described above, the variation time of the symbol variation is determined by the variation type counters CS1 and CS2, and the time to be added to or subtracted from the variation time is determined by the variation type counter CS3. Therefore, the final fluctuation time until the final stop symbol stops is determined by the fluctuation type counters CS1, CS2, CS3.

  The second random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). In this embodiment, the value of the second random number counter C4 is updated periodically, for example, every timer interrupt process, and the ball has passed through the second entrance (through gate) 67 on either the left or right side. Obtained when detected. The number of random number values to be won is 149, and the range is “5 to 153”. The second initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the second per-random number counter C4 (value = 0 to 250), and is once per timer interrupt process (see FIG. 17). As well as being updated, it is repeatedly updated within the remaining time of the main process (see FIG. 14).

  Next, a command output from the main control device 110 to the payout control device 111 will be described with reference to FIG. FIG. 11 is a diagram illustrating commands output from the main control device 110 to the payout control device 111. The command is composed of 2 bytes, and is output as 8-bit parallel data from the main controller 110 to the payout controller 111 via the connectors 207 and 217 in the order of the first byte and the second byte. In the first byte of the command, the most significant bit is set (“1”), and in the second byte, the most significant bit is reset (“0”). Therefore, the payout control device 111 can determine whether the input data is the first byte or the second byte of the command by setting or resetting the most significant bit.

  In the pachinko machine 10, not all commands shown in FIG. 11 are necessarily used. That is, there is also a pachinko machine 10 that uses only a part of the commands shown in FIG. For example, there is a pachinko machine 10 in which only a payout return command, a payout initialization command, a 5-ball award payout command, and a 15-ball award payout command are used.

  Data input / output between the main control device 110 and the payout control device 111 is performed only in one direction from the main control device 110 to the payout control device 111. This is because the number of input signals to the main control device 110 that performs the main control of the game is reduced as much as possible to suppress illegal acts on the main control device 110. For this reason, even if the output command data changes due to noise, signal line disconnection or short, fraud, etc., the main control device 110 cannot detect it and cannot detect an abnormality.

  Therefore, in this embodiment, when the command output from the main control device 110 to the payout control device 111 is composed of 2 bytes and these are added or exclusive ORed one byte at a time, the least significant 1 byte after the operation Is set to FFH. Therefore, in the payout control device 111, the input 2-byte command is added or exclusive-ORed byte by byte, and if the result is not FFH, the command is determined not to be a normal command and the command input Is invalidated, and a letter “C” is displayed on the 7-segment LED 121 provided in the payout control device 111 to notify a command error.

  Commands output from the main control device 110 to the payout control device 111 include a prize ball command for instructing the payout of prize balls. Since the prize ball command has a great influence on the player and the game hall, even if the output of the command is only one direction from the main control device 110 to the payout control device 111, it is input by the payout control device 111. It is configured so that it can be determined whether or not the command is normal.

  If there is a break in the signal line that outputs the prize ball command, it can be reliably detected by the above method (the result of addition or exclusive OR is FFH). That is, if any one of the signal lines is disconnected, the data (bit) of the signal line is always the same data (“0 and 0” or “1 and 1”) in both the first byte and the second byte. Therefore, when the first byte and the second byte of the command are added or exclusive ORed, the bit corresponding to the broken signal line becomes 0, and the result of the addition or exclusive OR does not become FFH. It is.

  Further, in the present embodiment, when the payout control device 111 is started up, the payout return command and the payout initialization command that are always output from the main control device 110 are used, and signal lines for transmitting these commands, It is possible to detect whether or not there is a short (solder bridge) in the connectors 207 and 217 connecting the signal lines.

  12A is a diagram showing an arrangement of signal pins of the connector 207 provided in the main control device 110, and FIG. 12B is an arrangement of signal pins of the connector 217 provided in the payout control device 111. FIG.

  A short of a signal line or a signal pin or a solder bridge occurs in an adjacent signal line (pin). As shown in FIG. 12A, the connector 207 of the main controller 110 has signal pins arranged adjacent to each other in bit order. Therefore, by setting the first byte of the payout initialization command to AAH (1010B) and the second byte to 55H (0101B), the adjacent signal line or signal pin of the connector 207 is changed according to the output of the payout initialization command. Alternately set or reset. Therefore, when the payout control device 111 can normally input the payout initialization command, it is possible to detect that there is no short circuit or solder bridge in these signal lines or signal pins.

  Further, the connector 217 of the payout device 111 has signal pins arranged in two stages as shown in FIG. Therefore, by setting the first byte of the payout return command to 99H (1001B) and the second byte to 66H (0110B), the signal lines adjacent in the vertical and horizontal directions of the connector 217 are output according to the output of the payout return command. Alternatively, the signal pins can be set or reset alternately. Moreover, by setting the first byte of the payout initialization command to AAH (1010B) and the second byte to 55H (0101B), the signal line or signal pin diagonally adjacent to the connector 217 is output according to the output of the payout initialization command. Can be set or reset alternately. Accordingly, when the payout control device 111 can normally input the payout return command and the payout initialization command, it is possible to detect that there is no short circuit or solder bridge in these signal lines or signal pins.

  The connector 217 may be configured with the arrangement shown in FIG. 12A, or the connector 207 may be configured with the arrangement shown in FIG. Furthermore, the main controller 110 and the payout controller 111 may be connected using a connector other than the arrangement shown in FIG. 12 (a) or FIG. 12 (b). In such a case, the payout return command and the payout initialization command are configured as data that alternately sets or resets signal lines or signal pins adjacent in the vertical and horizontal directions of the connector.

  Next, each control process executed by the MPU 201 in the main controller 110 will be described with reference to the flowcharts of FIGS. 13 to 19. The processing of the MPU 201 is roughly divided into a startup process that is started when the power is turned on, a main process that is executed after the startup process, and a timer that is started periodically (in this embodiment, at a cycle of 2 ms). There are an interrupt process and an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal. For convenience of explanation, the timer interrupt process and the NMI interrupt process are described first, and then the startup process The main process will be described.

  FIG. 17 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 201 of the main control device 110, for example, every 2 ms. In the timer interrupt process, first, a process for reading various winning switches is executed (S501). That is, the state of various switches connected to the main controller 110 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the first initial value random number counter CINI1 and the second initial value random number counter CINI2 are updated (S502). Specifically, the first initial value random number counter CINI1 is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (738 in the present embodiment). Then, the updated value of the first initial value random number counter CINI 1 is stored in the corresponding buffer area of the RAM 203. Similarly, the second initial value random number counter CINI2 is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (250 in the present embodiment), and the updated value of the second initial value random number counter CINI2 Is stored in the corresponding buffer area of the RAM 203.

  Further, the first per-random number counter C1, the first per-type counter C2, the stop pattern selection counter C3, and the second per-random number counter C4 are updated (S503). Specifically, 1 is added to each of the first per-random number counter C1, the first per-type counter C2, the stop pattern selection counter C3, and the second per-random number counter C4, and these counter values are the maximum values (this embodiment) Then, when 738, 4, 238, 250) are reached, they are cleared to 0. Then, the updated values of the counters C1 to C4 are stored in the corresponding buffer area of the RAM 203.

  Thereafter, a start winning process (see FIG. 18) associated with winning in the first entrance 64 is executed (S504), a firing control process is executed (S505), and the timer interrupt process is terminated. In the firing control process, it is detected that the player is touching the operation handle 51 by the touch sensor, and the firing of the ball is turned on / off on the condition that the firing stop switch for stopping the firing is not operated. It is a process to decide. When the launch of the sphere is on, the launch control device 112 is instructed to launch the sphere.

  With reference to the flowchart of FIG. 18, the start winning process executed in the process of S504 will be described. First, it is determined whether or not the ball has won the first entrance 64 (start winning) (S601). If it is determined that the ball has won the first entrance 64 (S601: Yes), whether or not the number N of the operation reserved balls of the first symbol display device 37 is less than the upper limit (4 in the present embodiment). Is determined (S602). If there is a winning at the first entrance 64 and the number of operation-reserved balls N <4 (S602: Yes), the number N of operation-reserved balls is incremented by 1 (S603), and further updated in step S503. The values of the first per-random number counter C1, the first per-type counter C2, and the stop pattern selection counter C3 are stored in the first area among the free reserved areas in the reserved ball storage area of the RAM 203 (S604). On the other hand, if there is no winning at the first entrance 64 (S601: No), or even if there is a winning at the first entrance 64, if the number N of operational balls is not less than 4 (S602: No) , S603 and S604 are skipped, the start winning process is terminated, and the process returns to the timer interrupt process.

  FIG. 19 is a flowchart showing the NMI interrupt process. The NMI interruption process is a process executed by the MPU 201 of the main controller 110 when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. By this NMI interrupt processing, information on occurrence of power interruption is stored in the RAM 203. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 252 to the NMI terminal of the MPU 201 in the main controller 110. Then, the MPU 201 interrupts the control being executed and starts the NMI interrupt process, stores the power-off occurrence information in the RAM 203 as a setting of the power-off occurrence information (S701), and ends the NMI interrupt process. To do.

  The above NMI interrupt process is executed in the same manner in the payout and emission control device 111, and information on the occurrence of power interruption is stored in the RAM 213 by the NMI interrupt process. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 252 to the NMI terminal of the MPU 211 in the payout and emission control device 111, and the MPU 211 interrupts the control being executed. Then, the NMI interrupt process is started.

  FIG. 13 is a flowchart showing start-up processing executed by the MPU 201 in the main controller 110. This start-up process is activated by a reset interrupt process at power-on. In the start-up process, first, an initial setting process associated with power-on is executed (S101). Specifically, a predetermined value set in advance in the stack pointer is set, and the sub-side control devices (peripheral control devices such as the audio lamp control device 113 and the payout control device 111) become operable. In order to wait, a wait process (1 second in this embodiment) is executed. Next, access to the RAM 203 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch 123 provided in the power supply device 115 is turned on (S104). If it is turned on (S104: Yes), the process proceeds to S110. On the other hand, if the RAM erasure switch 123 is not turned on (S104: No), it is further determined whether or not the information on occurrence of power interruption is stored in the RAM 203 (S105), and if not stored (S105: No). Since the backup data is not stored, in this case as well, the process proceeds to S110.

  If power failure occurrence information is stored in the RAM 203 (S105: Yes), a RAM determination value is calculated (S106). If the calculated RAM determination value is not normal (S107: No), that is, the calculated RAM determination is performed. If the value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed, and the process proceeds to S110 even in such a case. Note that the RAM determination value is, for example, a checksum value at the work area address of the RAM 203, as will be described later in the processing of S213 in FIG. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 203 is correctly stored.

  In the processing of S110, a payout initialization command (see FIG. 11) is transmitted in order to initialize the payout control device 111 serving as a sub-side control device (peripheral control device) (S110). Upon receiving this payout initialization command, the payout control device 111 clears an area (working area) other than the stack area of the RAM 213, sets an initial value, and enters a state in which game ball payout control can be started ( (See FIG. 24). After transmitting the payout initialization command, main controller 110 executes initialization processing (S111, S112) of RAM 203.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 123. Therefore, if the RAM erase switch 123 is pressed during the start-up process, the RAM initialization process (S111, S112) is executed. Similarly, initialization processing (S111, S112) of the RAM 203 is executed even when the information on occurrence of power interruption is not set or when a backup abnormality is confirmed by the RAM determination value (checksum value, etc.). . In the RAM initialization process (S111, S112), the used area of the RAM 203 is cleared to 0 (S111), and then the initial value of the RAM 203 is set (S112). After the initialization process of the RAM 203 is executed, the process proceeds to S113.

  On the other hand, if the RAM erasure switch 123 is not turned on (S104: No), information on occurrence of power shutdown is stored (S105: Yes), and if the RAM judgment value (checksum value etc.) is normal ( S107: Yes), the information on the occurrence of power interruption is cleared while the backed up data is held in the RAM 203 (S108). Next, a payout return command (see FIG. 11) at the time of power recovery for returning the sub-side control device (peripheral control device) to the gaming state at the time of driving power interruption is transmitted (S109), and the process proceeds to S113. To do. When the payout control device 111 receives this payout return command, the payout control device 111 is in a state where the payout control of the game ball can be started while holding the data stored in the RAM 213 (see FIG. 24).

  In the process of S113, an interrupt is permitted and the process proceeds to a main process described later.

  Next, the main process will be described with reference to the flowchart of FIG. In this main process, the main process of the game is executed. As an outline, each process of S201 to S206 is executed as a periodic process of a 4 ms cycle, and the counter update process of S209 and S210 is executed in the remaining time.

  In the main process, first, output data such as a command updated in the previous process is transmitted to each control device (peripheral control device) on the sub-side (S201). Specifically, the presence / absence of winning detection information detected in the switch reading process of S501 is determined, and if there is winning detection information, a winning ball command corresponding to the number of acquired balls is transmitted to the payout control device 111. As shown in FIG. 11, the prize ball command is composed of 15 types of 2-byte commands of FE01H to F00FH. By this external output processing, a total of 2 bytes are continuously transmitted through the connectors 207 and 217. The byte is transmitted (output) to the payout control device 111. In addition, by this external output process, a variation pattern command, a stop symbol command, a stop command, an effect time addition command, etc. required for the variation display of the third symbol by the third symbol display device 81 are transmitted via the connectors 208 and 228. It is transmitted (output) to the sound lamp control device 113. Furthermore, when launching a sphere, a sphere launch signal is transmitted (output) to the launch control device 112.

  Next, each value of the variation type counters CS1, CS2, CS3 is updated (S202). Specifically, 1 is added to the variation type counters CS1, CS2, and CS3, and when the counter values reach the maximum values (198, 240, and 162 in this embodiment), they are cleared to 0, respectively. Then, the update values of the variation type counters CS 1, CS 2, and CS 3 are stored in the corresponding buffer area of the RAM 203.

  When the update of the variation type counters CS1, CS2 and CS3 is completed, the winning ball counting signal and the payout abnormality signal received from the payout control device 111 are read (S203), and the process for displaying on the first symbol display device 37 is performed. A variation process for setting a variation pattern of the third symbol and the like by the three symbol display device 81 is executed (S204). Details of the variation process will be described later with reference to FIG.

  After the end of the variation process, a large opening opening / closing process for opening or closing the specific winning opening (large opening) 65a of the variable winning device 65 is executed in the case of the big win state (S205). That is, the specific winning opening 65a is opened for each round of the big hit state, and it is determined whether the maximum opening time of the specific winning opening 65a has elapsed or whether a specified number of balls have won the specific winning opening 65a. When any of these conditions is met, the specific winning opening 65a is closed. The opening and closing of the specific winning opening 65a is repeated for a predetermined number of rounds.

  Next, display control processing of the second symbol (for example, “◯” or “x” symbol) by the second symbol display device 82 is executed (S206). Briefly, on the condition that the ball has passed through the second entrance (through gate) 67, the value of the second random number counter C4 is acquired at the timing of the passage, and the second symbol display device 82 is obtained. In the display unit 83, the second symbol variation display is performed. Then, the lottery of the second symbol is performed based on the value of the second winning random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the first entrance 64 is released for a predetermined time.

  Thereafter, it is determined whether or not the information on the occurrence of power interruption is stored in the RAM 203 (S207). If the information on the occurrence of power interruption is not stored in the RAM 203 (S207: No), a power failure signal is output from the power failure monitoring circuit 252. SG1 is not output and the power supply is not shut off. Therefore, in such a case, it is determined whether or not the execution timing of the next main process has been reached, that is, whether or not a predetermined time (4 ms in the present embodiment) has elapsed since the start of the previous main process (S208). If the predetermined time has already passed (S208: Yes), the process proceeds to S201, and the processes after S201 described above are repeatedly executed.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous main process (S208: No), the first time is within the remaining time until the predetermined time is reached, that is, until the next main process is executed. The initial value random number counter CINI1, the second initial value random number counter CINI2, and the variation type counters CS1, CS2, CS3 are repeatedly updated (S209, S210).

  First, the first initial value random number counter CINI1 and the second initial value random number counter CINI2 are updated (S209). Specifically, the first initial value random number counter CINI1 and the second initial value random number counter CINI2 are incremented by 1 and cleared to 0 when the counter value reaches the maximum value (738, 250 in this embodiment). . Then, the updated values of the first initial value random number counter CINI1 and the second initial value random number counter CINI2 are stored in the corresponding buffer areas of the RAM 203, respectively.

  Next, the fluctuation type counters CS1, CS2 and CS3 are updated (S210). Specifically, 1 is added to the variation type counters CS1, CS2, and CS3, and when the counter values reach the maximum values (198, 240, and 162 in this embodiment), they are cleared to 0, respectively. Then, the update values of the variation type counters CS1, CS2, CS3 are stored in the corresponding buffer areas of the RAM 203, respectively.

  Here, since the execution time of each process of S201-S206 changes according to the state of the game, the remaining time until the next main process execution timing is not constant and varies. Therefore, by repeatedly performing the update of the first initial value random number counter CINI1 and the second initial value random number counter CINI2 using the remaining time, the first initial value random number counter CINI1 and the second initial value random number counter CINI2 (that is, , The initial value of the first per-random number counter C1 and the initial value of the second per-random number counter C4) can be updated at random. Similarly, the variation type counters CS1, CS2, and CS3 can be updated at random.

  In the process of S207, if the power failure occurrence information is stored in the RAM 203 (S207: Yes), the power failure is caused by the occurrence of a power failure or the power is turned off, and the power failure monitoring circuit 252 outputs the power failure signal SG1. As a result, since the NMI interrupt process of FIG. 19 has been executed, the power-off process after S211 is executed. First, the generation of each interrupt process is prohibited (S211), and a power-off notification command indicating that the power has been cut off is sent to other control devices (peripheral control devices such as the payout control device 111 and the sound lamp control device 113). It transmits to (S212). Then, the RAM determination value is calculated and stored (S213), access to the RAM 203 is prohibited (S214), and the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Here, the RAM determination value is, for example, a checksum value in the stack area and work area to be backed up in the RAM 203.

  It should be noted that the process of S207 is performed at the end of a series of processes corresponding to the game state change performed in S201 to S206, or at the end of one cycle of the processes of S209 and S210 performed within the remaining time. It is running. Therefore, in the main process of the main controller 110, the occurrence information of the power supply interruption is confirmed at the timing when each setting is completed. Therefore, when returning from the power interruption state, the process is performed after the start-up process is completed. It can start from the process of S201. That is, the process can be started from the process of S201 as in the case where the process is initialized in the startup process. Therefore, in the process at power-off, the stack pointer is not stored in the initial setting process (S101) without saving the contents of each register used by the MPU 201 to the stack area or saving the value of the stack pointer. By setting to a predetermined value (initial value), it is possible to start from the process of S201. Therefore, it is possible to reduce the control burden on the main control device 110 and to perform accurate control without causing the main control device 110 to malfunction or run away.

  Next, the variation process (S204) will be described with reference to the flowcharts of FIGS. In the variation process, first, it is determined whether or not the jackpot is currently being hit (S301). The jackpot includes the jackpot game displayed on the third symbol display device 81 and the middle of a predetermined time after the jackpot game ends. As a result of the determination, if it is a big hit (S301: Yes), this processing is terminated as it is.

  If it is not a big hit (S301: No), it is determined whether or not the display mode of the first symbol display device 37 is changing (S302), and if the display mode of the first symbol display device 37 is not changing. (S302: No), it is determined whether or not the number N of active suspension balls is greater than 0 (S303). If the number N of active balls is 0 (S303: No), this process is terminated as it is. If the number of the operation reservation balls N> 0 (S303: Yes), 1 is subtracted from the number N of operation reservation balls (S304), and the data stored in the storage ball storage area is shifted (S305). This data shift process is a process for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area. After the data shift process, the fluctuation start process of the first symbol display device 37 is executed (S306). The variation start process will be described later with reference to FIG.

  In the process of S302, if it is determined that the display mode of the first symbol display device 37 is changing (S302: Yes), it is determined whether or not the change time has passed (S307). The display time during fluctuation of the first symbol display device 37 is determined according to the fluctuation pattern selected by the fluctuation type counters CS1 and CS2 and the addition time selected by the fluctuation type counter CS3. If it has not elapsed (S307: No), the display of the first symbol display device 37 is updated (S308). In the present embodiment, among the LEDs 37a of the first symbol display device 37, for example, if the currently lit LED is red until the variation time elapses after the variation starts, the red LED is Turn off and turn on the green LED. If the green LED is on, turn off the green LED and turn on the blue LED. If the blue LED is on, turn on the blue LED. A display mode is set for turning off the red LED and turning on the red LED. The variation process is executed every 4 ms. However, if the LED lighting color is changed for each variation process, the player cannot confirm the change in the LED lighting color. Therefore, in order to make the player confirm the change of the LED lighting color, each time the change process is executed, a counter (not shown) is counted by 1 and when the counter reaches 100, the LED is turned on. The color is changed, and the lighting color of the LED is changed every 0.4 s. The counter value is reset (cleared to 0) when the lighting color of the LED is changed.

  On the other hand, if the variation time of the first symbol display device 37 has elapsed (S307: Yes), a display mode corresponding to the stop symbol of the first symbol display device 37 is set (S309). Whether or not the stop symbol is set is determined according to the value of the first random number counter C1, and if it is a big hit, the symbol that becomes a high probability state after the big hit by the value of the first hit type counter C2 Or a symbol that is in a low probability state is determined. In this embodiment, a red LED is turned on when a high probability state is reached after a big hit, a green LED is turned on when a low probability state is reached, and a blue LED is turned on when it is out of place. . In addition, although the lighting of each LED is released when the next fluctuation display is started, it may be turned on only for a few seconds after the fluctuation stops.

  When the display mode of the first symbol display device 37 corresponding to the stop symbol is set in the process of S309, the variation stop of the third symbol display device 81 is stopped to synchronize with the lighting of the LED in the first symbol display device 37. A command is set (S310). When the sound lamp control device 113 receives this stop command, it instructs the display control device 114 to stop. When the variation time elapses, the third symbol display device 81 stops the variation, and receives the stop command, whereby one variation effect in the third symbol display device 81 ends.

  Next, the variation start process will be described with reference to the flowchart of FIG. In the variation start process (S306), first, it is determined whether or not a big hit is made based on the value of the first hit random number counter C1 stored in the execution area of the reserved ball storage area (S401). Whether or not it is a big hit is determined based on the relationship between the first random number counter value and the mode at that time. As described above, “373,727” is a winning value among the numerical values 0 to 738 of the first per random number counter C1 at a normal low probability, and “59, 109, 163, 211, 263, 317, 367 at a high probability. , 421, 479, 523, 631, 683, 733 "is the winning value.

  When it is determined that it is a big hit (S401: Yes), the value of the first hit type counter C2 stored in the execution area of the reserved ball storage area is confirmed, and the display mode for the big hit is set (S402). ). In the process of S402, based on the value of the first hit type counter C2, whether to shift to the high probability state or shift to the low probability state after the big hit is set. When the transition state after the big hit is set, the display mode of the first symbol display device 37 (the lighting state of the LED 37a) is set. Further, based on the transition state after the jackpot, the jackpot stop symbol of the third symbol display device 81 is set by the display control device 114. That is, the stop symbol in the 3rd symbol display apparatus 81 can be set by setting the transition state after the big hit in the process of S402. Of the numerical values 0 to 4 of the first hit type counter C2, when “0, 4”, the state shifts to the low probability state, and when “1, 2, 3”, shifts to the high probability state.

  Next, a variation pattern at the time of jackpot is determined (S403). When the variation pattern is set in the process of S403, the display time of the first symbol display device 37 is set and the variation time of the third symbol until the third symbol display device 81 stops at the jackpot symbol is determined. The At this time, the values of the fluctuation type counters CS1 and CS2 stored in the counter buffer of the RAM 203 are confirmed, and rough symbol fluctuations such as normal reach, super reach, and premium reach are determined based on the value of the first fluctuation type counter CS1. In addition to determining the variation time, the variation time (in other words, the number of variation symbols) until the final stop symbol (in the present embodiment, the middle symbol Z2) stops after the occurrence of reach is determined based on the value of the second variation type counter CS2. decide.

  The relationship between the numerical value of the first variation type counter CS1 and the variation time, and the relationship between the numerical value of the second variation type counter CS2 and the variation time are respectively defined in advance by a table or the like. However, the fluctuation time can be set using only the value of the first fluctuation type counter CS1 without using the value of the second fluctuation type counter CS2, and can be set only with the value of the first fluctuation type counter CS1. Whether or not to set with both values of both variation type counters CS1 and CS2 is appropriately determined according to the value of the first variation type counter CS1 and the game conditions each time.

  If it is determined in the process of S401 that it is not a big hit (S401: No), the display mode at the time of disconnection is set (S404). In the process of S404, the display mode of the first symbol display device 37 is set to the display mode corresponding to the off symbol, and based on the value of the stop pattern selection counter C3 stored in the execution area of the reserved ball storage area, An effect to be displayed on the third symbol display device 81 is set as to whether the reach is front / rear out of reach, reach other than front / rear out, or complete out. In the present embodiment, as described above, the range of values corresponding to each stop pattern of the stop pattern selection counter C3 depends on whether the state is a high probability state, a low probability state, and the operation suspension number N. Different tables are set up.

  Next, the variation pattern at the time of detachment is determined (S405), the display time of the first symbol display device 37 is set, and the variation time of the third symbol until the third symbol display device 81 stops at the detachment symbol. Is determined. At this time, as in the process of S403, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 203 are confirmed, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. In addition, the fluctuation time (in other words, the middle symbol Z2 in the present embodiment) is stopped after the reach has occurred based on the value of the second fluctuation type counter CS2 For example, the number of fluctuation symbols) is determined.

  When the process of S403 or the process of S405 is completed, the effect time to be added to or subtracted from the variation time determined by the first and second type counters CS1 and CS2 is determined (S406). At this time, the addition / subtraction of effect time is determined based on the value of the third type counter CS3 stored in the counter buffer of the RAM 203, the display time of the first symbol display device 37 is set, and the third symbol display The variation time of the device 81 is set. In the present embodiment, the effect time addition / subtraction is determined according to the value of the third variation type counter CS3 when the variation display time is not changed and when the variation display time is added for one second, the variation display time is set to 2. In the case of adding seconds, four types of addition values are determined for the case of subtracting 1 second from the variable display time.

  In addition, when the variable display time is added or subtracted, a notice effect that increases the expected value of the jackpot on the third symbol display device 81 (for example, a slip effect that causes the change time of the variable symbol to be longer than usual and is accompanied by a slip) An effect of displaying a notice character is produced, for example, an effect of making the change time of one change symbol shorter than usual and stopping it immediately). In addition, when the value of the first random number counter C1 is a big hit, since the probability that the added value of 2 seconds is selected is set high, the player expects a big hit by confirming the notice effect. Can do.

  Next, a variation pattern command is set according to the variation pattern (variation time) determined in S403 or S405 (S407), and a stop symbol command is set according to the stop symbol set in S402 or S404. (S408). Then, an effect time addition command is set according to the added value of the effect time determined in the process of S406 (S409), and the process returns to the variation process.

  Next, payout control executed by the MPU 211 in the payout control device 111 will be described with reference to FIGS. FIG. 20 is a flowchart showing a start-up process of the payout control device 111, and this start-up process is executed when the power is turned on. First, an initial setting process associated with power-on is executed (S801). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Then, the RAM access is permitted (S802), and an external interrupt vector is set (S803).

  Thereafter, a data backup process is executed for the RAM 213 in the MPU 211. Specifically, it is determined whether or not the information on the occurrence of power interruption is stored in the RAM 213 (S804). If not stored (S804: No), the backup data is not stored, so the process proceeds to S811. Transition. If power failure occurrence information is stored in the RAM 213 (S804: Yes), a RAM determination value is calculated (S805). If the calculated RAM determination value is not normal (S805: No), that is, the calculated RAM determination is performed. If the value does not match the RAM determination value stored when the power is turned off, the backed up data has been destroyed. In such a case as well, the process proceeds to S811. As described later in the processing of S917 in FIG. 21, the RAM determination value is, for example, a checksum value at a work area address in the RAM 213. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 213 is correctly stored.

  In the RAM initialization process of S811 and S812, all areas of the RAM 213 are cleared to 0 (S811), and then the initial value of the RAM 213 is set (S812). Thereafter, the peripheral devices of the MPU 211 are initialized (S809), an interrupt is permitted (S810), and the process proceeds to the main process.

  On the other hand, if the occurrence information of power interruption is set (S804: Yes) and the RAM judgment value (checksum value etc.) is normal (S806: Yes), the data backed up in the RAM 213 is retained. In addition to clearing the information on the occurrence of power interruption (S807), the payout permission flag 213d is turned off (S808) in order to wait for the payout of the prize ball. Thereafter, the peripheral devices of the MPU 211 are initialized (S809), an interrupt is permitted (S810), and the process proceeds to the main process.

  Next, main processing executed by the MPU 211 in the payout control apparatus 111 will be described with reference to the flowchart of FIG. In this main process, first, a winning ball command, a payout return command, and a payout initialization command from the main control device 110 are received, and a command determination process for determining the type of these commands is performed (S901). Although details of the command determination process will be described later, in this process, when a normal command transmitted from the main control device 110 is received, the payout permission flag 213d is turned on and the payout of the winning ball or the loaned ball is permitted.

  That is, after execution of the command determination process (S901), the state of the payout permission flag 213d is determined (S902), and if the payout permission flag 213d is not turned on (S902: No), the main controller 110 is still in the started state. Therefore, in such a case, the command determination process (S901) is repeatedly executed until the payout permission flag 213d is turned on in the command determination process (S901). On the other hand, if the payout permission flag 213d is turned on in the processing of S902 (S902: Yes), the main control device 110 has already started up. In such a case, the state return switch 120 is checked and the state is checked. When it is determined that the return operation is started, the state return operation is executed (S903).

  Thereafter, the setting of the lower pan full tank state or the lower pan full tank release state is executed according to the change in the state of the lower pan 50 (S904). That is, when the lower pan 50 is determined based on the detection signal of the lower pan full switch, the lower pan full state is set when the lower pan is full. , Set the lower pan full release state. Further, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change in the state of the tank ball (S905). That is, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when the tank ball is not used, the tank ball no state setting is executed. Perform configuration. Thereafter, the presence / absence of a notification state is determined. If there is a notification state, notification is made by the 7-segment LED 121 provided in the payout control device 111 (S906). The state notification process will be described later with reference to FIG.

  Next, prize ball payout processing is executed by each processing from S907 to S909. That is, if the prize ball cannot be paid out and the value of the total prize ball number memory 213a for storing the number of prize balls is not 0 (S907: No, S908: No), the prize ball is paid out. The ball control process is started (S909). On the other hand, if the prize ball cannot be paid out (S907: Yes) or if the value of the total prize ball number memory 213a is 0 (S908: Yes), the process proceeds to a rental ball payout process.

  In the ball lending payout process from S910 to S912, if a ball lending payout request is not received and a ball lending payout request from the card unit is received (S910: No, S911: Yes), the ball lending is paid out. The ball rental control process is started. On the other hand, if the rental ball cannot be dispensed (S910: Yes) or if a rental ball dispensing request has not been received (S911: No), the process proceeds to S913. Similarly, after the ball rental control process (S912) is completed, the process proceeds to S913.

  In the process of S913, the control of the vibrator 134 (vibration motor control) is executed on the condition that the ball is clogged (S913). Thereafter, it is determined whether or not the occurrence information of power interruption is stored in the RAM 213 (S914). If the occurrence information of power interruption is not stored (S914: No), the power failure signal SG1 is received from the power failure monitoring circuit 252. Since it is not output and the power supply is not shut off, in such a case, the process proceeds to S901, and the main process from S901 to S913 is repeatedly executed.

  On the other hand, if the occurrence information of power interruption is stored in the process of S914 (S914: Yes), the result of the power failure is output due to the occurrence of a power failure or the power is turned off and the power failure monitoring circuit 252 outputs the power failure signal SG1. This means that the NMI interrupt process of FIG. 19 has been executed. Therefore, in such a case, the generation of each interrupt process is prohibited (S915), and the command determination process is executed again in order to prevent the reception of a command transmitted from the main controller 110 (S916). Then, the RAM determination value is calculated and stored in the RAM 213 (S917), access to the RAM 213 is prohibited (S918), and the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Here, for example, the RAM determination value is a checksum value in the stack area and the work area to be backed up in the RAM 213.

  In the process of S914, since the information on the occurrence of power interruption is confirmed at the timing when one cycle of the main process of the payout control device 111 ends, the process is started up when returning from the state before the power interruption. After the process is completed, the process can be started from S901. In other words, the main process can be started in the same manner as when initialized in the startup process. Therefore, in the process at power-off, the contents of each register used by the MPU 211 are not saved in the stack area, or the stack pointer value is not saved in the initial setting process (S801) without saving the stack pointer value. By setting to a predetermined value (initial value), the process can be started from S901. Therefore, the control burden on the payout control device 111 can be reduced, and accurate control can be performed without causing the payout control device 111 to malfunction or run away. In addition, since the power-off process is executed at the timing when each process is completed, the amount of information to be backed up in the RAM 213 can be reduced.

  FIG. 22 is a flowchart showing a command determination process executed in the main process of the payout control device 111. The command determination process determines whether or not the received command is a normal command, and executes a process corresponding to the command if the received command is a normal command.

  First, it is checked whether there is a new reception command (S1001). If there is no new reception command (S1001: No), this process is terminated. If there is a new reception command (S1001: Yes), it is determined whether the reception command is the first byte data or the second byte data (S1002). As described above with reference to FIG. 11, if the most significant bit is set, it is the first byte data (S1002: Yes). In this case, is the value of the upper command storage buffer 213b 0? (S1003).

  When 2 bytes of command are received, the value of the upper command storage buffer 213b is cleared to 0. Therefore, if the command is normal, the value of the upper command storage buffer 213b is 0 when the first byte data is received. Therefore, if the value of the upper command storage buffer 213b is not 0 (S1003: No), some abnormality has occurred, so the payout error flag 213c is turned on (S1004), and the process proceeds to S1005. On the other hand, if the value of the upper command storage buffer 213b is 0 (S1003: Yes), the process of S1004 is skipped and the process proceeds to S1005. In the process of S1005, the received first byte data is written into the upper command storage buffer 213b and stored (S1005).

  In the process of S1002, if the received command is not the first byte data but the second byte data (S1002: No), the received command is the second byte data and the upper command is stored in S1005 process. The value stored in the buffer 213b, that is, the first byte data is added (S1006). If the result of the addition is FFH (S1007: Yes), since the received command is normal, it is checked whether the value of the upper command storage buffer 213b is F0H or more (S1008).

  As shown in FIG. 11, when the value of the upper command storage buffer 213b is equal to or greater than F0H (S1008: Yes), the received command is a prize ball command. In this case, a prize ball payout number setting process is executed. (S1009). On the other hand, if the value of the upper command storage buffer 213b is not equal to or greater than F0H (S1008: No), the received command is a payout return command or a payout initialization command. In such a case, a state setting process is executed ( S1010). After execution of the winning ball payout number setting process or the state setting process, the process proceeds to S1001, and the above-described process is repeated. The prize ball payout number setting process or the state setting process will be described later.

  In the process of S1007, if the result of the addition of the first byte data and the second byte data is not FFH (S1007: No), some abnormality has occurred. Therefore, in such a case, the payout error flag 213c is turned on (S1011) to indicate the occurrence of a command error, the value of the upper command storage buffer 213b is cleared to 0 (S1012), and the received 2-byte command is displayed. Disable it. Thereby, malfunction of the payout control apparatus 111 due to reception of an abnormal command can be prevented. After the process of S1012, the process proceeds to S1001, and the above-described process is repeated.

  FIG. 23 is a flowchart showing a prize ball payout number setting process (S1009) executed in the command determination process. In the prize ball payout number setting process, the value of the total prize ball number memory 213a is updated according to the received prize ball command.

  First, it is checked whether or not the number of prize balls of the received prize ball command is 1 or more and 15 or less (S1101). Otherwise (S1101: No), an incorrect prize ball command is received (FIG. 11). reference). Therefore, in such a case, the received command is invalidated and this process is terminated.

  On the other hand, if the number of prize balls of the received prize ball command is 1 or more and 15 or less (S1101: Yes), the number of prize balls designated by the prize ball command is added to the total prize ball number memory 213a (S1102). The added number of prize balls is paid out by the above-described prize ball control process (S909). Thereafter, the value of the upper command storage buffer 213b is cleared to 0 (S1103), and in preparation for receiving the next command, the payout permission flag 213d is turned on (S1104), and the payout of the winning ball is permitted. Further, the payout error flag 213c is turned off (S1105), and this process is terminated.

  In this way, since the payout error flag 213c is turned off by receiving a normal command, even if an abnormal command is temporarily input due to noise or the like, by inputting the normal command, The command error notification can be canceled and the game can be continued normally.

  FIG. 24 is a flowchart showing the state setting process (S1010) executed in the command determination process. In the state setting process, a process according to the payout return command or the payout initialization command is executed.

  If the received command is a payout return command (S1201: Yes), the process proceeds to S1206. Then, the payout permission flag 213d is turned on (S1206), the payout of the prize ball is permitted, the value of the upper command storage buffer 213b is cleared to 0 (S1207), and a payout error is further prepared in preparation for reception of the next command. The flag 213c is turned off (S1208), and this process ends.

  If the received command is a payout initialization command (S1201: No, S1202: Yes), the state of the payout permission flag 213d is checked (S1203). If the payout permission flag 213d is off (S1203: No), the payout initialization command is normally received. In this case, the work area of the RAM 213 is cleared to 0 (S1204), and is initialized to the work area. An initial value for the hour is set (S1205), and the work area of the RAM 213 is initialized.

  Thereafter, as in the case of receiving the payout return command, the payout permission flag 213d is turned on (S1206), the payout of the winning ball is permitted, and the value of the upper command storage buffer 213b is cleared to 0 (S1207). In addition, the payout error flag 213c is turned off (S1208), and the process is terminated.

  Even if the received command is a payout initialization command (S1201: No, S1202: Yes), if the payout permission flag 213d is turned on (S1203: Yes), one of the normal ones shown in FIG. Upon receiving the command, the prize ball payout control is enabled. Therefore, in such a case, in order to avoid initialization of the work area of the RAM 213, the processing from S1204 to S1206 is skipped, and the processing proceeds to S1207. Thereafter, the value of the upper command storage buffer 213b is cleared to 0 (S1207), the payout error flag 213c is turned off (S1208) in preparation for the reception of the next command, and this process is terminated.

  If the received command is neither a payout return command (S1201: No) nor a payout initialization command (S1202: No), it means that an incorrect prize ball command has been received (see FIG. 11). In this case, the received command is invalidated and this process is terminated.

  FIG. 25 is a flowchart showing a state notification process (S906) executed in the main process. In the status notification process, first, the status of the payout error flag 213c is confirmed (S1301), and if it is turned on (S1301: Yes), the character “C” is displayed on the 7-segment LED 121 to generate a command error. Notification is made (S1302). On the other hand, when the payout error flag 213c is not turned on (S1302: No), or after the processing of S1302, other states of the payout control device 111 such as the full state of the lower plate 50 and the storage state of the tank balls. (S1303), and this process is terminated.

  As described above, according to the pachinko machine 10 of the present embodiment, a command output from the main control device 110 to the payout control device 111 is composed of 2 bytes, and these are added or exclusive ORed one byte at a time. In addition, the least significant byte after the calculation is set to FFH. Therefore, in the payout control device 111, the input 2-byte command is added or exclusive-ORed byte by byte, and if the result is not FFH, the command is determined not to be a normal command and the command input Is invalidated, and a letter “C” is displayed on the 7-segment LED 121 provided in the payout control device 111 to notify a command error. Therefore, since the payout control device 111 can input only normal commands as valid commands, it is possible to normally perform payout control of games and prevent payouts that are not specified or due to fraudulent acts. .

  In addition, when a command that is not normal is input, the 7 segment LED 121 notifies the fact (occurrence of a command error), so that when the pachinko machine 10 is disconnected or an illegal act is performed on the pachinko machine 10. In the event of a failure, it is possible to quickly detect and deal with them. Further, when a normal command is input during command error notification, the command error notification is terminated. Therefore, even when an abnormal command is temporarily input due to the influence of noise or the like, the notification can be canceled and the game can be continued normally by inputting the normal command.

  Further, when the payout control device 111 is started up, the payout return command and the payout initialization command that are always output from the main control device 110 are used to connect the signal lines for transmitting these commands and the signal lines. Whether or not there is a short (solder bridge) in the connectors 207 and 217 can be detected. Therefore, since the game can be executed without such an abnormality, it is possible to normally output a command from the main control device 110 to the peripheral control device 111 and to normally perform prize ball payout control.

  In an inspection performed at a production factory before shipment of the pachinko machine 10, it is possible to check for disconnection or short-circuit by simply turning on the power of the pachinko machine 10 and turning on the power after initializing the contents of the RAM. Therefore, it is not necessary to open the front frame 14 and put a ball into the general winning entrance 63 or the first entrance (starting entrance) 64 for inspection, and the inspection process can be made more efficient. .

  FIG. 26 shows the second embodiment. In the second embodiment, the fixing sheet metal 153 and the heat sink 156 constituting the shield part 151 of the substrate box 101 of FIG. 4 according to the present embodiment are integrated. Other configurations are the same as those in FIG. 4, and the board box 101 is disposed on the display control device 114 that controls the display contents and the display control device 114, and is emitted from the display control device 114. A unit type shield unit 171 that blocks electromagnetic noise, a third symbol display device 81 that displays the contents controlled by the display control device 114, a front panel 142 that fixes the third symbol display device 81, and a display control device 114. And a third symbol display device 81 fixed to the front panel 142, to which a display control device 114 is attached, a substrate holder 141, a display control device 114, a unit type shield part 171, a substrate holder 141, and a third A transparent rear case 140 that houses the symbol display device 81 with the front panel 142 as a lid. It is made.

  The unit-type shield unit 171 disposed on the display control device 114 shown in FIG. 27 has an adhesive heat that is attached to the upper surface of the MPU 231 and the image controller 236 and the MPU 231 and the image controller 236 mounted on the display control device 114. A conductive silicone rubber sheet 157; and a unit type heat sink 173 that is in contact with the silicone rubber sheet 157 to radiate heat from the MPU 231 and the image controller 236 to the space while having thermal conductivity, and to have conductivity. A unit type that is formed integrally with the unit type heat sink 173 and that is formed of a metal sheet metal that blocks electromagnetic noise radiated from the MPU 231, the image controller 236, and the display control device 114 and has thermal conductivity. Fixing sheet metal 172 and unit type fixing A display control device that is formed in a side surface of the metal plate 172 to promote air circulation and improve the visibility inside the unit mold fixing sheet metal 172, and a part of the lower end of the unit mold fixing sheet metal 172. The grounding tool 174 that is in contact with the grounding surface of the conductive plate 162 and also electrically connected to the grounding surface of the unit-type fixing sheet metal 172 is in contact with the grounding surface of the display control device 114. In addition, an air-cooling that is electrically connected and is fixed by a adjusting unit 175 that adjusts the distance from the grounding tool 174, a unit-type fixing sheet metal 172, and a conductive screw 160, and forcibly generates air circulation. Fan 152. The tip of the adjustment unit 175 penetrates from the hole 159 formed in the display control device 114 to the back surface of the display control device 114.

  Here, since the unit mold fixing sheet metal 172 and the unit mold heat sink 173 are integrally formed, a conductive screw for connecting the unit mold fixing sheet metal 172 and the unit mold heat sink 173 becomes unnecessary, and both the members 172, 172 The attachment of 173 can be simplified. Further, since both the members 172 and 173 are integrally formed, the conductivity of both the members 172 and 173 can be kept good and a high shielding effect can be obtained. The unit-type fixing sheet metal 172 and the unit-type heat sink 173 formed integrally form a shield member. Alternatively, the unit mold fixing sheet metal 172 and the unit mold heat sink 173 may be integrally formed and integrated.

  In addition to the grounding tool 174 and the adjustment unit 175, the unit type fixing sheet metal 172 is not connected to the ground surface of the display control device 114, and the shield unit 171 is attached to the upper surface of the display control device 114. You may provide the auxiliary | assistant part which assists holding. Although the shape of the auxiliary portion is substantially the same as that of the adjustment portion 175, the tip thereof is formed shorter than the adjustment portion 175 and is supported on the upper surface of the display control device 114. That is, the adjustment unit 175 penetrates the back surface of the display control device 114 through the hole 159, but the auxiliary unit is supported on the upper surface of the display control device 114.

  FIG. 28 shows a cross-sectional view when the components shown in FIG. 27 are assembled. A silicone rubber sheet 157 is overlaid on the MPU 231 and the image controller 236 mounted on the display controller 114, and a unit heat sink 173 is overlaid on the silicone rubber sheet 157. The unit mold heat sink 173 is formed integrally with the unit mold fixing sheet metal 172, and the grounding tool 174 of the unit mold fixing sheet metal 172 is fixed to the ground surface of the display control device 114 by a conductive screw 162. An air cooling fan 152 is fixed to the unit type fixing sheet metal 172 with a conductive screw 160. With this structure, the air cooling fan 152, the unit type fixing sheet metal 172, and the unit type heat sink 173 are electrically connected to the ground plane of the display control device 114. Therefore, the air cooling fan 152, the unit-type fixing sheet metal 172, and the unit-type heat sink 173 exhibit a function of blocking electromagnetic noise. Thereby, the electromagnetic noise radiated | emitted from the display control apparatus 114 can be interrupted | blocked. Therefore, malfunction of other circuit boards due to electromagnetic noise radiated from the display control device 114 can be prevented. Further, even if electromagnetic noise is generated by the air cooling fan 152, this electromagnetic noise can also be blocked. Further, since there is an appropriate space between the unit mold fixing sheet metal 172 and the display control device 114, air circulation inside the unit mold fixing sheet metal 172 is facilitated as compared with the case where there is no such space. Become.

  FIG. 29 is a perspective view when the components shown in FIG. 27 are assembled. Here, except for the portion where the grounding tool 174 and the adjustment tool 175 are formed, the lower end of the unit-type fixing sheet metal 172 is disposed at a distance d2 from the display control device 114. Further, the grounding tools 174 are arranged with a distance a2, the grounding tool 174 and the adjusting tool 175 are arranged with a distance b3, and the adjusting tools 175 are arranged with a distance c2. Further, the hole 176 is formed by a quadrangle having a long side length f2. The distances a2, b2, c2, the distance d2, and the long side length f2 are all set to less than one half of the shortest wavelength of electromagnetic noise to be cut off. As a result, the electromagnetic noise having the wavelength shorter than the shortest wavelength to be blocked cannot resonate in each space portion of the distances a2, b2, c2, the distance d2, and the long side length f2. Therefore, compared to the case where the distances a2, b2, c2, the distance d2, and the long side length f2 are all set to one half or more of the shortest wavelength of electromagnetic noise, the electromagnetic waves radiated from these spaces The amount of noise radiation can be suppressed. Therefore, except for the portion where the grounding tool 174 and the adjustment tool 175 at the lower end of the unit-type fixing sheet metal 172 are formed, the display control device 114 and the grounding tool 174 are arranged at a predetermined distance d2. The grounding tool 174 and the adjusting tool 175 are spaced apart from each other by a distance b2, the adjusting tools 175 are spaced from each other by a distance c2, and the hole 176 may be formed by a rectangle having a long side length f2. Electromagnetic noise radiation can be suppressed.

  In the above description, the distances a2, b2, c2, the distance d2, and the long side length f2 are all set to be less than one half of the shortest wavelength of electromagnetic noise to be blocked. It may be less than one half of the shortest wavelength of the electromagnetic noise that selects and cuts off any one of the parameters c2, the distance d2, and the long side length f2. In this case, compared with the case where the selected parameter among the distances a2, b2, c2, the distance d2, and the long side length f2 is set to one half or more of the shortest wavelength of the electromagnetic noise to be cut off, The amount of electromagnetic noise emitted from the space can be suppressed.

  Next, even if the air cooling fan 152 forcibly generates air circulation in the unit mold fixing sheet metal 172, there are gaps due to the spaces of distances a2, b2, c2, distance d2, and long side f2. Air circulation between the inside and outside of the unit mold fixing sheet metal 172 is smoothly performed. Therefore, even if the display control device 114 is covered with the unit mold fixing sheet metal 172, the display control device 114 inside the unit mold fixing sheet metal 172 can be forcibly cooled by the circulation of air by the air cooling fan 152. It is possible to suppress thermal runaway of the element mounted on the board. Further, since the air cooling fan 152 is used, it is possible to generate air circulation locally in the unit heat sink 173 portion that needs to be cooled even on the display control device 114. Therefore, the cooling effect can be enhanced as compared with the case where the air in the unit-type fixing sheet metal 172 is circulated evenly.

  Further, since the grounding tool 174 and the adjusting tool 175 at the lower end of the unit type fixing sheet metal 172 are arranged apart from the display control device 114 by a predetermined distance d2, the grounding tool 174 Wiring 165 and the like can be formed on the substrate portion on the display control device 114 other than the portion where the adjustment tool 175 is in contact with the ground plane of the display control device 114. Therefore, the substrate can be effectively used as compared with the case where the entire lower end of the unit-type fixing sheet metal 172 is brought into contact with the substrate.

  The display control device 114 is covered with the unit-type fixing sheet metal 172. For this reason, the electromagnetic noise radiated | emitted from the part which radiates | emits electromagnetic noise can be interrupted | blocked by covering the part which radiates | emits electromagnetic noise which is the whole or a part of the display control apparatus 114 with a shield member. Therefore, it is possible to prevent malfunctions caused by electromagnetic noise emitted from other elements mounted on the same display control device 114 that are not covered by the shield member, while preventing malfunction due to electromagnetic noise of the main controller 110. .

  Further, since it is not necessary to cover main controller 110 with unit-type fixing sheet metal 172, MPU 202 mounted on main controller 110 can be visually observed. Therefore, it is possible to solve the problem that the MPU 202 mounted on the main control device 110 cannot be seen, which may occur when the main control device 110 is covered with the fixing sheet metal 153. Furthermore, since the MPU 202 mounted on the main control device 110 can be visually checked, it is possible to detect unauthorized exchange of the main control device 110.

  FIG. 30 is a diagram showing a third embodiment. This third embodiment excludes the cooling fan 152, the heat sink 156, the top hole 163, and the hole 164 in the shield part 151 that blocks electromagnetic noise radiated from the display control device 114 of FIG. It is a configuration. The other configuration is exactly the same as the configuration of FIGS. In the case of the configuration shown in FIG. 30, the following effects are exhibited although it is the simplest configuration of the present invention.

  Except for the part where the grounding tool 154 and the adjustment tool 155 at the lower end of the fixing metal plate 153 are formed, the display control device 114 and the grounding tool 154 are separated from each other by a distance a. Even if the tool 154 and the adjuster 155 are spaced apart by a distance b and the adjusters 155 are spaced from each other by a distance c, the distances a, b, c, and the distance d are all dichotomized by the shortest wavelength of electromagnetic noise to be cut off. It is set to less than one. As a result, electromagnetic noise having the wavelength shorter than the shortest wavelength that can be cut off cannot resonate in each space portion of the distances a, b, c, and the distance d. Therefore, the amount of electromagnetic noise radiated from these spaces is suppressed as compared with the case where the distances a, b, c, and the distance d are all set to one half or more of the shortest wavelength of electromagnetic noise. be able to.

  Further, since the lower end of the fixing sheet metal 153 is disposed at a predetermined distance d from the display control device 114 except for the portion where the grounding tool 154 and the adjusting tool 155 are formed, the space that is the gap is not formed. Through this, air is circulated between the inside and the outside of the fixing sheet metal 153. Therefore, even if the display control device 114 is covered with the fixing metal plate 153, the display control device 114 inside the fixing metal plate 153 can be naturally cooled by air circulation, and thermal runaway of the elements of the display control device 114 is suppressed. It becomes possible.

  Further, since the grounding tool 154 and the adjusting tool 155 at the lower end of the fixing sheet metal 153 are arranged apart from the display control device 114 by a predetermined distance d, the grounding tool 154 and the adjusting tool are arranged. Wiring 165 and the like can be formed on the substrate portion on the display control device 114 other than the portion where the terminal 155 is in contact with the ground plane of the display control device 114. Therefore, the substrate can be effectively used as compared with the case where the entire lower end of the fixing sheet metal 153 is brought into contact with the substrate.

  In addition, the display control device 114 is covered with the fixing metal plate 153. For this reason, the electromagnetic noise radiated | emitted from the part which radiates | emits electromagnetic noise can be interrupted | blocked by covering the part which radiates | emits electromagnetic noise which is the whole or a part of the display control apparatus 114 with a shield member. Therefore, it is possible to prevent malfunctions caused by electromagnetic noise emitted from other elements mounted on the same display control device 114 that are not covered by the shield member, while preventing malfunction due to electromagnetic noise of the main controller 110. .

  Further, since it is not necessary to cover main controller 110 with fixing sheet metal 153, MPU 202 mounted on main controller 110 can be visually observed. Therefore, it is possible to solve the problem that the MPU 202 mounted on the main control device 110 cannot be seen, which may occur when the main control device 110 is covered with the fixing sheet metal 153.

  Furthermore, since the MPU 202 mounted on the main control device 110 can be visually checked, it is possible to detect unauthorized exchange of the main control device 110.

  In the present embodiment and the second embodiment, the cooling fan 152 is attached to the upper surface of the heat sink 156 or the unit heat sink 173 as a means for forcibly circulating air. The cooling fan 152 and the heat sink 156 or the upper surface of the unit heat sink 173 are connected by a pipe, and forced air circulation is generated by the air from the pipe. Good. In this case, since the cooling fan 152 is attached at a location away from the display control device 114, the display from the cooling fan 152 is compared with the case where the cooling fan 152 is attached to the upper surface of the heat sink 156 or the unit heat sink 173. The influence of electromagnetic noise on the control device 114 can be suppressed.

  As described above, the present invention has been described based on each embodiment, but the present invention is not limited to the above-described embodiment, and various modifications can be easily made without departing from the gist of the present invention. Can be inferred.

  In the present embodiment, the shielding of electromagnetic noise radiated from the display control device 114 has been described. However, the present invention is not necessarily limited to this, and the present invention is applied to the payout control device 111 and the sound lamp control device 113. Also good.

  Next, although this embodiment demonstrated the command output to the payout control apparatus 111 from the main control apparatus 110, it is not necessarily limited to this, For example, the audio lamp control apparatus 113 from the main control apparatus 110, The present invention may be applied to commands output to other peripheral control devices. When applied to a command output to the audio lamp control device 113, it can be configured to perform a game effect only when a normal effect command is input, so that the game effect control is performed normally. Can be made. In such a case, the signal line is set so that adjacent pins are alternately set / reset according to the arrangement of the signal pins of the connectors 208 and 228 that connect the main controller 110 and the sound lamp controller 113. Configure commands to detect shorts and solder bridges.

  When an abnormal command is input, the occurrence of a command error is notified by the 7-segment LED 121. Instead of this, a lamp (lamp display device (lighting unit) provided on the front surface of the pachinko machine 10 is used instead. 29 to 33 and the display lamp 34))) may be turned on or blinked, or a predetermined error sound or the like may be output from a speaker (audio output device 226) for notification. Furthermore, the occurrence of the command error may be output to the hall computer 262 via the external output terminal board 261. If the occurrence of the command error is output to the hall computer 262, the occurrence of the error can be immediately reported to the game hall manager. In addition, if the pachinko machine 10 is configured not to notify the command error but to output only to the hall computer 262, if a player enters an abnormal command as a result of cheating, It is possible to notify the manager of the game hall of the cheating without being noticed by the player who cheated. Therefore, it can be used for extracting fraudsters.

  Furthermore, although the present embodiment is applied to a command composed of 2 bytes, the present invention may be applied to a command composed of 3 bytes or more or a command composed of 1 byte. For example, when the command is composed of 3 bytes or more, addition or exclusive OR is performed on the first predetermined input data and the second predetermined input data, and the result is determined. . Further, the first predetermined input data and the second predetermined input data are set so that the outputs of the adjacent signal pins of the connector are alternately set / reset. On the other hand, when the command is composed of 1 byte, for example, addition and exclusive OR are performed on the upper 4 bits of data and the lower 4 bits of data, and the result is determined. In such a case, the command is output 4 bits at a time, and the 4-bit data is set so that the outputs of the adjacent signal pins of the connector are alternately set / reset.

  The command was output from the main controller 110 as 8-bit parallel data. However, the present invention is not necessarily limited to this. For example, it may be configured to output the data bit by bit by a serial method. In this case, data input by a peripheral control device such as the payout control device 111 is, for example, grouped together every 4 bits or 8 bits into one group of data, and the addition of the data of that group and the data of another group or An exclusive OR may be performed to check whether the output command is normal or not.

  Although the payout return command shown in FIG. 11 is composed of 9966H and the payout initialization command is composed of AA55H, it may be composed of AA66H and 9955H, 5566H and AA99H. Further, the connectors 207, 208, 217, and 228 are constituted by the two-row array connectors shown in FIG. 12B, and the output pins of the input / output port 205 of the main controller 111 that outputs commands to these connectors are arranged in one row. The input pins of the input / output ports 215 and 225 of the payout control device 110 and the sound lamp control device 113 for inputting commands output from these connectors may be arranged in a line.

  In the present embodiment, the winning that is detected by the winning detection means is that the ball that has been driven into the game area wins any of the winning openings 63, 64, 65a. However, when the present invention is applied to a slot machine or a game ball using spinning game machine that uses a game ball to perform a spinning game, the winning detected by the winning detection means depends on the operation of the start lever. It becomes the lottery result performed in the game machine.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that generates a special game that gives a player a predetermined game value on the condition that a ball is won in a predetermined area. Further, the present invention may be implemented in a pachinko machine that has a special area such as a V-zone and has a special gaming state as a prerequisite that a ball is awarded in the special area. Further, in addition to the pachinko machine, the game machine may be implemented as various game machines such as an alepatchi, a sparrow ball, a slot machine, a game machine in which a so-called pachinko machine and a slot machine are integrated.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Accordingly, the basic concept of the slot machine is that it is provided with a display device for confirming and displaying the identification information after variably displaying the identification information string composed of a plurality of identification information, and resulting from the operation of the starting operation means (for example, the operation lever). The variation display of the identification information is started, and the variation display of the identification information is stopped and fixedly displayed due to the operation of the operation means for stop (for example, the stop button) or when a predetermined time elapses. It is a slot machine that generates a special game that gives a player a predetermined game value on the condition that the combination of identification information at the time is a specific condition. In this case, the game medium is typically a coin, medal, etc. Take as an example.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a display device is provided that displays a symbol after a symbol string composed of a plurality of symbols is variably displayed, and has a handle for launching a ball. What is not. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the variation of the symbol is stopped, and a special game that gives a predetermined game value to the player is generated on the condition that the determined symbol at the time of stoppage is a so-called jackpot symbol. In this case, a large amount of balls are paid out to the lower tray.
