Description

  The present invention relates to a gaming machine that can detect the opening and closing of a door that is openably and closably attached to the front surface of a housing.

  Conventionally, slot machines and pachinko machines such as pachinko shops installed in game halls such as so-called pachinko shops, repair and exchange of various parts provided in the housing, adjustment of the ball appearance rate, medals, etc. In order to perform operations such as replenishment of game media (especially a slot machine), a front surface of the housing (a surface facing the player) is an opening, and a door that can open and close the opening is attached. Thereby, an attendant of the game hall can come into contact with various components installed inside the housing by opening the door. In addition, this door is usually provided with a locking mechanism, and its key is managed in the game hall, and an unauthorized device is attached so that an unspecified person can open the door and acquire more payout of game media. In addition, fraudulent acts such as taking out the game media stored in the housing cannot be performed.

  However, even if a locking mechanism is provided on the door described above, there is a possibility that an operator may forget to lock the door after work, or that the door may be forcibly opened despite being locked. is there. Therefore, it is conceivable that, when such a situation occurs, when a door attached to the housing is opened, it is detected and notified to a game attendant or the like when the door is opened. In order to realize this, it is necessary to detect the opening and closing of the door. For example, a lever type or push button type switch is attached to the housing, and when the door is closed, It is conceivable that the button is tilted or pushed and the switch is turned on when the door is closed. As a result, it is possible to detect that the door is closed when the switch is ON, and that the door is open when the switch is OFF.

  As a means for detecting the opening and closing of the door, for example, in the gaming machine disclosed in Patent Document 1, a photosensor including a light emitter and a light receiver is provided inside the housing, and a light shielding plate is provided on the door side. When the door is closed, the light shielding plate blocks the light emitted from the light emitter to the light receiver. As a result, when the door is closed, the light emitted from the light emitter is shielded by the light shielding plate, the light detection signal is not output from the photosensor, and when the door is opened, the light emitted from the light emitter is Light is received by the light receiver, and a photodetection signal is output from the photosensor, whereby the opening / closing of the door can be detected. In this way, by adopting a non-contact type switch using a photo sensor as a door detection means, the durability of the switch itself and the reliability of the detection result are improved compared to the case of using a mechanical switch. Can do.

  By the way, in the above-described gaming machine, generally, a light source such as a lamp or an LED or a liquid crystal display device for displaying an image is provided on the front surface of the gaming machine in order to perform a visual effect during the game. It is provided in front of the door described above. In recent years, in order to further improve the production effect, the number of light emitting sources to be installed has increased, and the screen size of the liquid crystal display device tends to increase. For this reason, when a photosensor is used as a means for detecting the opening / closing of the door, the light emitted from the light source or the backlight of the liquid crystal display device may leak into the housing, and an error may occur in the detection result.

  Accordingly, an object of the present invention is to detect the opening / closing of the door without being affected by the light even when light from a light source attached to the door of the housing leaks into the housing. It is to provide a gaming machine.

  In order to achieve the above object, the present invention provides a gaming machine having a door attached to a front surface of a housing so as to be freely opened and closed, the magnetic flux generating means provided on the door for generating magnetic flux, and the housing.

  Here, as the “magnetic flux generating means”, for example, a permanent magnet, a DC electromagnet, an AC electromagnet, or the like can be used.

  According to the present invention, when the door attached to the casing of the gaming machine is opened, the magnetic flux generating means and the voltage generating means are at least shifted from the opposing positions, or the distance between them is increased. The voltage generated in the generating means fluctuates, and the opening / closing detecting means detects the fluctuation of the voltage, so that the opening / closing of the door can be detected. That is, in the gaming machine of the present invention, since a mechanical switch or photosensor is not used, the durability of the door opening / closing detection means is not deteriorated and the light leaking into the housing is not affected. The opening and closing of the door of the gaming machine can be detected.

  In the gaming machine according to the present invention, the magnetic flux generation means changes the magnetic flux generated by an AC power supply and a first coil connected to the AC power supply, and the voltage generation means A second coil for generating a current corresponding to a change in the magnetic flux generated by the magnetic flux generating means; a rectifier for rectifying the current generated in the second coil and outputting a DC voltage corresponding to the rectified current; The open / close detection means is configured such that the door is opened when the magnitude of the voltage output from the voltage generation means is smaller than the magnitude of the voltage generated when the door is closed. It is characterized by detecting.

  According to the present invention, since the magnetic flux is generated using the AC power source in the magnetic flux generating means, the alternating current is constantly applied to the second coil in the voltage generating means while the door of the gaming machine is closed. It can be generated and rectified by a rectifier to obtain a DC voltage, and the opening / closing of the door can be detected based on the DC voltage. For this reason, the value of the voltage output from the rectifier accompanying the opening / closing of the door can be easily detected, and the opening / closing detection of the door with high accuracy can be performed.

  According to the gaming machine of the present invention, even when the light of the light source attached to the door of the housing leaks into the housing, the opening / closing of the door can be detected without being affected by the light. it can.

  Next, with reference to FIG. 2, the configuration inside the housing of the slot machine 1 will be described. The housing of the slot machine 1 includes a box 1a having an opening on the front surface and a front door 1b attached to the box 1a by a hinge H so that the opening can be opened and closed. FIG. 2 is a diagram showing a state in which the front door 1b is opened. In this figure, the same parts as those shown in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  Inside the box 1a, a main controller 30 that controls the game of the slot machine 1 is detachably attached above the back plate of the box 1a. In addition, a middle board 1c is provided substantially in the center of the box 1a, and a reel unit 24 for rotatably supporting the reels 4L, 4C, 4R is placed on the middle board 1c.

On the left side of the hopper 25 of the bottom plate 1d, a power supply device 26 that supplies power to each part of the slot machine 1 is installed. A push button type reset switch 26a is provided on the front face of the power supply device, which is operated by an attendant at a game hall when stopping the door opening notification described later.

  A liquid crystal panel 3 is attached to the back side of the front door 1b, and cold cathode tubes 300a and 300b are attached to the back side of the liquid crystal panel 3 so as to sandwich the reel display windows 5L, 5C, 5R from above and below. Yes. The cold cathode tubes 300a and 300b are provided to improve the visibility of the reels 4L, 4C, and 4R. That is, even if the liquid crystal panel 3 is controlled so that the transmittance of the reel display windows 5L, 5C, and 5R is maximized, a part of the light passing through the area is polarized by the polarizing filter or the liquid crystal panel 3 Since it is absorbed by the color filter or the like, the scene seen through the reel display windows 5L, 5C, and 5R becomes dark, and the visibility of the symbol is lowered. Therefore, by providing the cold cathode fluorescent lamps 300a and 300b, the illumination with respect to the symbols is made brighter and the visibility of the symbols is prevented from being lowered. On the back surface of the liquid crystal panel 3, a driving unit 301 including a backlight incorporated in the liquid crystal panel 3 and an inverter circuit for causing the cold cathode fluorescent lamps 300a and 300b to emit light is attached. Further, a magnetic flux generator 27 for generating magnetic flux is provided on the upper side of the liquid crystal panel 3 and on the hinge H side. The magnetic flux generator 27 is generated at a position facing the magnetic flux generator 27 on the box 1a side. A magnetic flux detection unit 28 is provided for detecting the generated magnetic flux.

  Here, with reference to FIG. 3, the structure of the magnetic flux generation part 27 and the magnetic flux detection part 28, and the detection principle of the magnetic flux by the magnetic flux detection part 28 are demonstrated. Here, FIG. 3 is a diagram schematically showing a circuit configuration of the magnetic flux generation unit 27 and the magnetic flux detection unit 28, and FIG. 3A shows a state where the front door 1b is closed, and FIG. b) shows a state in which the front door 1b is being opened. In this figure, the magnetic flux generator 27 includes a core 271, a coil 272 wound around the core 271, and an AC power supply 273 that supplies AC power to the coil 272. The AC power supplied from the AC power supply 273 to the coil 272 is specifically generated in the power supply device 26 shown in FIG. On the other hand, the magnetic flux detection unit 28 has a core 281, a coil 282 wound around the core 281, a diode bridge 283 connected to the coil 282, and two input terminals, and the diode bridge 283 is one input terminal. And a comparator 284 to which the reference voltage is supplied to the other input terminal. Here, the value of the reference voltage supplied to the other input terminal of the comparator 284 is set to a value lower than the voltage supplied from the diode bridge 283 when the front door 1b is closed. . At this time, how low the value of the reference voltage is set may be appropriately determined based on the relationship between the angle when the front door 1b is opened and the voltage value output from the diode bridge 283.

  In FIG. 3A, when the front door 1b is closed, AC power is supplied to the coil 272, whereby magnetic flux is alternately applied to the core 271 in the directions of arrows indicated by solid lines and broken lines in the figure. Occurs. Thus, the coil 272 corresponds to the first coil. The magnetic flux generated in the core 271 passes through the core 281 of the magnetic flux detection unit 28, and thereby a current flows through the coil 282. Therefore, the coil 282 corresponds to the second coil. This current is rectified by the diode bridge 283 so that a DC voltage is supplied to one input terminal of the comparator 284. This diode bridge 283 corresponds to a rectifier. Then, the comparator 284 compares the voltage supplied from the diode bridge 283 (hereinafter simply referred to as supply voltage) with the reference voltage. At this time, since the value of the supply voltage exceeds the value of the reference voltage (the value of the reference voltage is set as such), an “H” level detection signal is sent from the comparator 284 to the main control unit described later. Is output. On the other hand, when the front door 1b is opened, the magnetic flux passing through the core 281 of the magnetic flux detection unit 28 decreases, and the current flowing through the coil 282 decreases. As a result, the value of the supply voltage output from the diode bridge 283 decreases. When the value of the supply voltage becomes equal to or lower than the reference voltage value in the comparator 284, the main control unit 30 detects the “L” level. A signal is output. Thereby, the comparator 284 corresponds to an open / close detection means. The main control unit 30 determines that the front door 1b is closed when the “H” level detection signal is output from the magnetic flux detection unit 28, and the front side when the “L” level detection signal is output. It is determined that the door 1b is open. Here, as the specific voltage values of the “H” level and the “L” level, values used in a general TTL (Transistor-Transistor Logic) circuit are used.

  Next, with reference to FIG. 4, the structure of the control part which performs control regarding the game and effect in the slot machine 1 is demonstrated. In FIG. 4, the same parts as those shown in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted. The control unit of the slot machine 1 includes a main control unit 30 and a sub control unit 60. The main control unit 30 mainly performs control related to games performed in the slot machine 1 such as insertion of medals, rotation / stop of reels, and payout at the time of winning. The sub-control unit 60 performs control related to effects such as light, sound, images, etc., which are mainly executed with games.

  The main control unit 30 includes a microcomputer (hereinafter referred to as a microcomputer) 31 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 31 includes a main CPU 32 that performs a control operation according to a preset program, a program ROM 33 and a control RAM 34 that are storage means, and an I / O port 39 for exchanging signals with various input / output devices described later. Including.

  The program ROM 33 of the microcomputer 31 stores various tables such as a symbol table, a probability lottery table, a stop table group, and a symbol combination table in addition to a program for performing game control in the slot machine 1.

  The symbol table associates each step of the stepping motors 240L, 240C, and 240R respectively corresponding to the reels 4L, 4C, and 4R with each symbol drawn on the reels 4L, 4C, and 4R and information on the type of the symbol. It is a thing. The main control unit 30 refers to the symbol table to perform stop control for each reel, and recognizes symbols that are stopped and displayed on the reel display windows 5L, 5C, and 5R.

  The probability lottery table defines the correspondence between each numerical value in the numerical value range 0-16383 (integer) of the random number generated by the random number generator 37, which will be described later, and each predetermined role. This is referred to when the internal lottery based on the result of random number sampling by 38 is performed. Each predetermined combination described above is associated with a specific symbol combination constituted by symbols drawn on the reels 4L, 4C, and 4R, and the symbol combination is stopped and displayed along the active line. In the case, the combination corresponding to the symbol combination is established.

  The stop table group is composed of a plurality of stop tables defined for each of the types of effective lines, the result of the internal lottery, and the reels 4L, 4C, and 4R. On the other hand, the number of sliding frames (maximum of 4 symbols) is associated. Here, the number of sliding symbols means that when a certain symbol on the reel comes to a predetermined position (for example, middle stage) in the reel display window and the stop switch is operated by the player, the symbol moves further from the symbol position. The number of symbols to be displayed is shown. For example, if the number of sliding symbols “1” is associated with a certain symbol and the stop switch is operated when the certain symbol comes to the middle in the reel display window, the next symbol following the certain symbol The reel stops when reaches the middle in the reel display window. This stop table is referred to when the reel stop control is performed in accordance with the operation of the stop switches 15L, 15C, 15R. As a result, when a winning combination is won in the internal lottery, a stop table is selected in which the symbol combination corresponding to the winning combination in the internal lottery can be stopped and displayed along the active line within a maximum of 4 frames. As stated in the program. On the other hand, when the internal lottery is lost, it is determined that a stop table is selected such that a symbol combination corresponding to some combination is not stopped and displayed along the active line.

  The symbol combination table is a table in which each of the predetermined combinations described above, the symbol combinations corresponding to the respective combinations, and the medal payout numbers corresponding to various winning combinations are associated. This table is referred to when determining whether or not any combination is established after all the reels 4L, 4C, 4R are stopped.

  Next, various information generated in the process of the main CPU 32 performing processing is set in the control RAM 34. For example, a flag (indicating whether the number of medals stored in the slot machine 1, the result of internal lottery, the type of winning combination, and door opening notification for notifying that the front door 1 b is open) Hereinafter, the door opening notification flag is stored. Here, when the value of the door opening notification flag is “0”, it indicates that the door opening notification described later is not performed, and when it is “1”, it indicates that the door opening notification is performed. . These pieces of information are transmitted to the sub control unit 60 via the sub control unit communication port 40. Various information exchanges between the main control unit 30 and the sub control unit 60 are performed in one direction from the main control unit 30 to the sub control unit 60, and from the sub control unit 60 to the main control unit 30. Does not send any information.

  Further, the main CPU 32 includes a clock pulse generation circuit 35 that generates a reference clock pulse, a frequency divider 36 that periodically generates and outputs an interrupt signal by dividing the reference clock pulse, and the random number generation described above. And a sampling circuit 38 that samples the random number generated by the random number generator 37 when the start switch 17 is tilted. Further, the main CPU 32 performs processing based on the reference clock pulse generated by the clock pulse generation circuit 35, and performs constant door opening monitoring processing described later using a pulse signal (interrupt signal) generated by the frequency divider 36 as a trigger. Run every hour.

  Note that the method for extracting the random number is not limited to the above, and the random number sampling may be executed on the operation program of the main CPU 32. In this case, the random number generator 37 and the sampling circuit 38 can be omitted, but may be left as they are for backup of the random number sampling operation without being omitted.

  The main output devices whose operation is controlled by a control signal from the microcomputer 31 include various displays (excluding the liquid crystal panel 3) provided on the front panel 2 shown in FIG. 1, and the hopper 25 shown in FIG. There are stepping motors 240L, 240C, 240R attached to the reel unit 24 shown in FIG. 2 for rotating the reels 4L, 4C, 4R (including a drive unit for paying out). The microcomputer 31 is connected to the BET lamps 7a, 7b and 7c provided on the front panel 2 through the lamp driving circuit 41, the hit display lamp WN constituting the gaming state display lamp group 10, the re-game display lamp RP, the game standby display The lamp WT, the start lamp ST, and the insert lamp IN are driven and controlled. Further, the microcomputer 31 drives and controls the seven-segment display of the bonus count display unit 6, the stored number display unit 8, and the payout number display unit 9 through the display unit drive circuit 42. Further, the microcomputer 31 controls driving of the hopper 25 via the hopper driving circuit 43 and controls driving of the stepping motors 240L, 240C, 240R via the motor driving circuit 44. The various drive circuits described above are connected to the main CPU 32 via the I / O port 39, and each receives a control signal such as a drive command output from the main CPU 32 to control the operation of the corresponding output device. .

  Next, as a main input device that generates an input signal necessary for the microcomputer 31 to generate a control command, first, a medal sensor 12S for detecting a medal inserted into the medal slot 12, and BET switches 13, 14 There are switches such as stop switches 15L, 15C, 15R, start switch 17, and medal discharge switch 18. Further, a detection signal output from the magnetic flux detection unit 28 illustrated in FIG. 3 is also output to the main CPU 32 via the I / O port 39. For the stop switches 15L, 15C, and 15R, a stop instruction signal corresponding to the stop switch pressed by the player is output from the reel stop signal circuit 51 and output to the main CPU 32 via the I / O port 39. The

  In addition to the switches described above, the main CPU 32 also receives signals output from photocouplers (not shown) provided corresponding to the reels 4L, 4C, and 4R, respectively. These photocouplers are connected to a reel position detection circuit 45 in the main control unit 30, and when a reference position provided for each corresponding reel is detected, a reference position signal corresponding to that reel is output from the reel position detection circuit 45. Is output to the main CPU 32 via the I / O port 39. Further, the main CPU 32 also receives a signal output from a medal detection unit 52 that detects medals paid out by the hopper 25. The medal detection unit 52 outputs a detection signal to the payout signal generation circuit 46 in the main control unit 30 every time the hopper 25 ejects one medal. The payout signal generation circuit 46 outputs the detection signal output from the medal detection unit 52 to the main CPU 32 via the I / O port 39.

  The sub control unit 60 receives various information transmitted from the main control unit 30 via the sub control unit communication port 40. Then, the contents of the effect to be executed are determined based on the received information, and the drive control of the upper lamp 22, the image display control for the liquid crystal panel 3, and the sound output control from the speakers 23L and 23R are performed according to the determined contents of the effect. Do.

  Next, game control executed by the control unit configured as described above will be described. Before the game is started, the microcomputer 31 causes the insert lamp IN to blink through the lamp driving circuit 41. When a player inserts a medal from the medal slot 12 or operates the BET switch 13 or 14, the microcomputer 31 turns off the insert lamp IN via the lamp driving circuit 41 and inserts the medal inserted. The BET lamps 7a, 7b, 7c are turned on according to the number of sheets. Further, when a medal insertion operation is performed by the BET switch 13 or 14, the BET lamps 7a, 7b, 7c are appropriately turned on according to the number of inserted medals and displayed on the stored number display unit 9. The value is changed to a value obtained by subtracting the number of sheets entered. Then, the game can be started, and the start lamp ST is blinked to prompt the player to operate the start switch 17.

  Thereafter, when the player performs a tilting operation of the start switch 17, the microcomputer 31 starts one game. That is, the start lamp ST is turned off, and the stepping motors 240L, 240C, and 240R are driven via the motor driving circuit 44 to rotate the reels 4L, 4C, and 4R. In addition, the random number generated by the random number generator 37 is sampled by the sampling circuit 38, and an internal lottery is performed based on the sampled random number and the probability lottery table stored in the program ROM 33 to determine the combination in the game. When one of the stop switches 15L, 15C, 15R is operated by the player, a stop signal corresponding to the operated stop switch is output from the reel stop signal circuit 51 to the microcomputer 31. Thereby, the microcomputer 31 performs the stop control of the reel corresponding to the operated stop switch based on the stop control table stored in the program ROM 33. In this stop control, when a replay combination or some winning combination is won as a result of the internal lottery, symbol combinations corresponding to these combinations are stopped and displayed as much as possible (within a maximum of 4 symbols) along the active line. To be done. In addition, if the result of the internal lottery is off, even if the player operates the stop switch at the timing when the symbol combination corresponding to the replay role or some winning combination is aligned on the active line, those roles are played along the active line. Stop control is performed so that the symbol combinations corresponding to are not complete.

  When all the reels are stopped, the microcomputer 31 refers to the symbol combination table stored in the program ROM 33 to make a winning determination. That is, it is determined whether or not there is a symbol combination corresponding to any combination along the effective line, and as a result, the symbol combination corresponding to any combination is stopped along the effective line (that is, the combination is established) ), The processing corresponding to the combination is performed. For example, when a winning combination is established, the hopper 25 is driven through the hopper driving circuit 43 to pay out a predetermined number of medals and paid out to the payout number display unit 8 through the display unit driving circuit 42. Display the number of medals. Then, the insert lamp IN indicating that the next game can be started is blinked via the lamp driving circuit 41. If a replay role is established, the game is finished as it is, and the same number of BET lamps as the game in which the replay role is established are turned on, and then the start lamp ST is turned on so that replay is possible. To do. On the other hand, if the game is lost, the insert lamp IN indicating that the game is finished and the next game can be started is blinked.

  Further, the main control unit 30 provides information such as the number of medals inserted into the game, the result of the internal lottery, and the result of the winning determination through the sub-control unit communication port 40 in the game control process described above. Transmit to the sub-control unit 60. Thereby, the sub control unit 60 determines an effect to be executed based on the received various information, and controls the light emission of the upper lamp 22, the display control of the image displayed on the liquid crystal panel 3 according to the determined effect, the speaker 23L, 23R audio output control is performed.

  In addition to the game control described above, the main control unit 30 performs door opening monitoring processing for monitoring the open / closed state of the front door 1b. The details of the door opening monitoring process will be described below with reference to the flowchart shown in FIG. The door opening monitoring process shown in FIG. 5 is a process executed by the main CPU 32 every time an interrupt signal is output from the frequency divider 36 shown in FIG.

  That is, when an interrupt signal is output from the frequency divider 36, the main CPU 32 interrupts the currently executing process and starts the door opening monitoring process shown in FIG. First, the main CPU 32 determines whether door opening notification is being executed (step S1). That is, the main CPU 32 reads the value of the door opening notification flag stored in the control RAM 34 described above. When the value is “0”, the door opening notification is not performed, and when the value is “1”, the door opening notification is performed. Judge that When the value of the door opening notification flag is “0”, the determination result in step S1 is NO, and the main CPU 32 determines whether or not an “H” level detection signal is output from the magnetic flux detection unit 28 ( Step S2). If the “H” level detection signal is output from the magnetic flux detection unit 28, the determination result in step S2 is YES, and the main CPU 32 ends the door opening monitoring process shown in FIG. Restart the process.

  On the other hand, if an “L” level detection signal is output from the magnetic flux detection unit 28, the determination result in step S2 is NO, and the main CPU 32 displays the door opening notification flag stored in the control RAM 34. The value is set to “1” and the door opening notification is started. In order to notify the door opening, for example, the main CPU 32 transmits a door opening notification start command to the sub control unit 60 via the sub control unit communication port 40. Receiving this command, the sub-control unit 60 turns on the upper lamp 22 with a predetermined special lighting pattern, displays a message such as “The door is open!” On the liquid crystal panel 3, and the speakers 23L and 23R. The control for outputting a predetermined alarm sound is executed. At this time, in the main control unit 30, the medal inserted into the medal slot 12 is discharged from the medal outlet 20, the operation of the BET switches 13, 14 is invalidated, or the reels 4L, 4C, 4R. If the slot machine is rotating, a process such as stopping the rotation of all reels may be performed to perform control such that the game cannot be performed, thereby disabling the slot machine 1. Then, when the sub-control unit 60 starts the door opening notification in the process of step S3, the main CPU 32 ends the door opening monitoring process of FIG. 5 and resumes the other processes that have been interrupted.

  If the value of the door opening notification flag stored in the control RAM 34 is “1” in step S1 described above, that is, if the door opening notification has already been performed, the determination result in step S1 is YES, and the main The CPU 32 determines whether or not a reset switch 26a (see FIG. 2) provided on the front surface of the power supply device 26 has been turned on (step S4). If the reset switch 26a has not been turned ON, the determination result in step S4 is NO, and the main CPU 32 ends the door opening monitoring process of FIG. 5 as it is, and resumes the other processes that have been interrupted. Therefore, in this case, the door opening notification is continuously performed. On the other hand, if the reset switch 26a is ON, the determination result in step S4 is YES, and the main CPU 32 terminates the door opening notification to the sub control unit 60 via the sub control unit communication port 40. The command is transmitted, and after a predetermined time (for example, 30 seconds) has elapsed, the value of the door opening notification flag stored in the control RAM 34 is reset to “0” (step S5). Receiving this command, the sub-control unit 60 stops the lighting on the upper lamp 22, the message display on the liquid crystal panel 3, and the alarm sound output from the speakers 23L and 23R. If the main CPU 32 disables the slot machine 1, the disabling is canceled and the game can be executed again. When the process of step S5 is completed, the main CPU 32 ends the door opening monitoring process of FIG. 5 and resumes the other processes that have been interrupted. Then, when the predetermined time (30 seconds here) elapses, the value of the door opening notification flag is reset to “0”, the process of step S2 is performed again, and the door opening monitoring state is set.

  In the slot machine 1 described above, when the front door 1b is opened illegally, for example, by breaking the locking device provided on the front door 1b, the magnetic flux detection unit 28 provided on the box 1a detects “L”. A level detection signal is output. Based on this detection signal, the main CPU 32 shifts to the process of step S3 based on the determination in step S2 of the door opening monitoring process shown in FIG. 5, and causes the sub-control unit 60 to start the door opening notification. Thus, since the door opening notification is started based on the detection signal output from the magnetic flux detection unit 28, for example, the door opening notification is provided to improve the visibility of the symbols drawn on the reels 4L, 4C, 4R. The opening of the front door 1b can be detected without being affected by light from the cold cathode fluorescent lamps 300a and 300b. Moreover, once the door opening notification is executed, the notification is continuously performed until the reset switch 26a provided in the power supply device 26 is turned on. That is, after the door opening notification is started, simply closing the front door 1b does not stop the notification, so it is difficult to open and close the front door 1b due to fraud. Of course, it is needless to say that the door opening notification may be stopped when the front door 1b is closed (that is, when an “H” level detection signal is output from the comparator 284).

  In the slot machine 1 described above, the magnetic flux generator 27 is composed of the core 271, the coil 272, and the AC power supply 273, but a permanent magnet or a DC electromagnet may be used instead. In this case, the magnetic flux detection unit 28 recognizes the opening of the front door 1b by detecting the counter electromotive force generated in the coil 282 of the magnetic flux detection unit 28 due to the magnetic flux change caused by opening the front door 1b. Can do. In the door opening monitoring process shown in FIG. 5, the door opening notification is started when the front door 1b is opened. For example, a legitimate key is inserted into the keyhole 16 and a locking device provided in the gaming door 1b is installed. When the front door 1b is opened by unlocking, the door opening notification may not be performed, and the door opening notification may be started when the front door 1b is opened without unlocking the locking device. Further, in the door opening monitoring process shown in FIG. 5, the door opening notification is stopped when the reset switch 26a is turned on. For example, the front door 1b is closed, and further, the locking provided on the front door 1b. The door opening notification may be stopped when the device is locked.
