  In the present embodiment, as shown in FIG. 6, the board box 263 is attached to the back frame set 215 via the connection plate 480 so as to be freely opened and closed. More specifically, a substantially box-shaped pedestal portion 481 is attached to the back frame set 215 fixed to the back surface of the game board 30. As shown in FIGS. 13 and 14, the pedestal portion 481 has a halved structure that is divided into two parts in the front and rear, a base housing 481 a that is fixed to the back frame set 215, and a cover housing 481 b that is assembled to the base housing 481 b by screws 482. It consists of. FIG. 13 is a perspective view of a unit in which the board box 263, the connection plate 480, the pedestal 481 and the like are assembled together, and FIG. 14 is an exploded perspective view showing the assembly relationship.

  A shaft hole 483 opening upward is formed inside the pedestal 481 by assembling both housings 481a and 481b.

  Although not shown in the drawings, the cover housing 481b is attached with a locking fitting similar to the locking fitting 476.

  On the other hand, the connection plate 480 includes a flat plate portion 480a to which the substrate box 263 is assembled, and a connecting portion 480b to which the pedestal portion 481 and the substrate box 263 are respectively connected.

  The connecting portion 480b is provided to extend in the front-rear direction on the left side portion of the plate portion 480a when viewed from the front side of the plate portion 480a to which the substrate box 263 is assembled.

  A box shaft portion 485 protruding upward is provided at the front end portion of the connecting portion 480b, and a base shaft portion 486 protruding downward is provided at the rear end portion. At the substantially central portion in the longitudinal direction of each shaft portion 485, 486, flange portions 485a, 486a projecting in the outer peripheral direction are formed. The flange portions 485a and 486a are formed in a tapered shape so as to taper toward the protruding direction of the respective shaft portions 485 and 486.

  Then, when the box shaft portion 485 is inserted into the bearing portion 472 of the substrate box 263 and is pushed in while elastically deforming the folded portion 476b of the locking metal fitting 476, the flange portion 485a of the box shaft portion 485 is turned back. When passing through 476a, the folding portion 476a returns to the original state. As a result, the box shaft portion 485 cannot be detached from the bearing portion 472, and the substrate box 263 is assembled to the connection plate 480 so as to be capable of relative rotational displacement about the shaft portion 485.

  Similarly, by inserting the pedestal shaft portion 486 into the pedestal portion 481 fixed to the back frame set 215 (game board 30), the pedestal shaft portion 486 cannot be detached from the pedestal portion 481, and the connection plate 480 and the board box 263 are assembled to the back frame set 215 so as to be capable of relative rotational displacement.

  As a result, it is possible to suppress an illegal act of removing the regular board box 263 from the connection plate 480 and replacing the board board 263 with the unauthorized main controller 261.

  Further, a locking claw 487 is formed on the plate portion 480a. Then, by locking the locking claw 487 with the locked portion 488 of the substrate box 263, the substrate box 263 is fixed in a state of being in contact with the plate portion 480a.

  Furthermore, a spacer 490 that fills a gap formed between the connection plate 480 and the back frame set 215 is attached to the back surface of the connection plate 480.

  The box cover 263a is provided with a pin holding portion 492 for holding an unused locking pin 491 at a position above the bearing portion 472 (cover-side housing 472a). As will be described later in detail, the locking pin 491 is used when the substrate box 263 is once opened and then the substrate box 263 is sealed again.

  The pin holding portion 492 is formed with a through-hole portion 493 in which the locking pin 491 is held in the inserted state. The outer peripheral shape of the head of the locking pin 491 and the inner peripheral shape of the through-hole portion 493 are formed in substantially the same shape, and there is almost no gap between them. Normally, the locking pin 491 has its head held flush with the surface of the pin holding portion 492. For this reason, the act of pinching the locking pin 491 with the head of the locking pin 491 sandwiched between pliers or the like is prevented.

  Corresponding to the pin holding portion 492, a locked portion 494 capable of locking the locking pin 491 is formed on the box base 263b.

  Next, a procedure for assembling the box cover 263a and the box base 263b will be described with reference to FIGS.

  First, the guide flange portion 424 of the box cover 263a is inserted into the guide rail 423 of the box base 263b and slid to the state shown in FIGS. 15 (a), 16 (a), and 17 (a). When viewed from the front side of the substrate box 263, the relative displacement direction in which the box cover 263a is moved to the right with respect to the box base 263b is the sealing direction, and the opposite left direction is the opening direction.

  Subsequently, the cover body portion 401 of the box cover 263a is inserted into the inserted portion 440 of the box base 263b, and the cover side connecting portion 430 is inserted into the base side connecting portion 450 through the communication hole 451. At this time, the rear connecting portion 432 of the cover side connecting portion 430 is inserted into the guide groove portion 457 of the base side connecting portion 450 to perform alignment.

  Further, when the box cover 263a is slid, the engaging portion 435c of the cover side connecting metal fitting 435 comes into contact with the engaging portion 454c of the base side connecting metal fitting 454, and the engaging portion 454c is elastically deformed. When the stepped portion 401g of the box cover 263a reaches a position where it abuts on the edge of the inserted portion 440 of the box base 263b, the engaging portion 435c of the cover side connecting metal 435 engages with the base side connecting metal 454. Overcoming the portion 454c, as shown in FIGS. 15B, 16B, and 17B, both engaging portions 435c and 454c are engaged. Thereby, the connection is completed and the substrate box 263 is sealed.

  When in the connected state, the base-side connecting metal fitting 454 enters a state between the pair of guard portions 435b of the cover-side connecting metal fitting 435.

  Further, the front connecting part 431 of the cover side connecting part 430 and the front wall part 450a of the base side connecting part 450 are overlapped, and the corners of the upper and lower wall parts 450c and 450d of the base side connecting part 450 and the rear wall part 450b. The guide portion 458 and the rear connecting portion 432 of the cover side connecting portion 430 are superposed (see FIG. 18).

  Further, the right wall portion 401e of the box cover 263a (cover body portion 401) comes into contact with the right wall portion 440a of the inserted portion 440 of the box base 263b, and the main control device (main control board) 261 is disposed. The main body (substrate housing space) of the board box 263 is separated from the connecting portion (engaging portion housing space) where the coupling fittings 435 and 454 are arranged. Therefore, the right wall 401e constitutes a partition wall in the present embodiment.

  Next, the procedure for opening the substrate box 263 will be described.

  First, a tip end portion of a tool such as a nipper or a cutter is inserted into the cutting slit 455 of the base side connecting portion 450, and the cover side connecting portion 430 and the base portion of the base side connecting portion 450 are cut. At this time, the front connecting portion 431 of the cover side connecting portion 430 and the front wall portion 450a of the base side connecting portion 450 are cut together. Similarly, the upper and lower wall portions 450c and 450d of the base side connection portion 450 and the guide portion 458 at the corner portion of the rear wall portion 450b and the rear connection portion 432 of the cover side connection portion 430 are cut together.

  As a result, the cover side connecting portion 430 is disconnected from the cover main body portion 401 of the box cover 263a, and the base side connecting portion 450 is disconnected from the inserted portion 440 of the box base 263b.

  Next, an operation for sealing the substrate box 263 again will be described.

  First, in a state where the box cover 263a and the box base 263b are assembled, the locking pin 491 on the box cover 263a side is pushed into the depth of the through-hole portion 493. Then, the locking pin 491 protrudes from the back side of the pin holding portion 492 and is locked to the locked portion 494 on the box base 263b side. As a result, the head of the locking pin 491 is immersed in the through hole 493, so that the box cover 263a and the box base 263b are detachably connected, and the substrate box 263 is sealed again. The

Data is backed up. Note that if data stored in at least the stack area and the backup area 513a is backed up, it is not always necessary to back up data stored in all areas. For example, the data stored in the stack area and the backup area 513a may be backed up, and the data stored in the work area may not be backed up.

  The backup area 513a has a stack pointer, each register at the time of power off, each register, so that the power of the pachinko machine 10 is restored to the state before the power is turned off when the power is turned off. This is an area for storing values such as I / O. The writing to the backup area 513a is executed when the power is turned off by the main process, and the restoration of each value written to the backup area 513a is executed in the main process when the power is turned on. As with the CPU 501 of the main controller 261, the power failure signal SK1 is input to the NMI terminal of the CPU 511 from the power failure monitoring circuit 542 when the power is interrupted due to the occurrence of a power failure or the like. When input to the CPU 511, NMI interrupt processing as power failure processing is immediately executed.

It is turned off when it is restored before the process or power shutdown. In the present embodiment, the specific commands are a payout initialization command for instructing the initial processing of the RAM 513 of the payout control device 311, a prize ball command for instructing payout of a prize ball, and the main controller 261 having been restored to power. There are three payout return commands to be transmitted in this case.

  The command reception flag is a flag for confirming whether or not the payout control device 311 has received a command, and is turned on when any command is received. Similar to the payout permission flag, an initial setting process or power-off is performed. It is turned off when returning to the front, and turned off when the command received by the command determination process is determined.

  The command buffer is configured by a ring buffer that temporarily stores commands transmitted from the main control device 261.

  An input / output port 515 is connected to the CPU 511 incorporating the ROM 512 and the RAM 513 through a bus line 514 including an address bus and a data bus. A RAM erase switch circuit 543, a main controller 261, a launch controller 312 and a payout device 358 are connected to the input / output port 515, respectively.

  The card unit connection board 314 includes a ball rental operation unit (a ball rental button 121 and a return button 122) on the front surface of the pachinko machine 10, and a card unit (a ball rental unit) arranged on the side of the pachinko machine 10 in a game hall or the like. Are electrically connected to each other, and receive a ball lending operation command from the player and output it to the card unit. In a cash machine in which game balls are lent directly to the upper plate 19 from a ball lending device or the like without using a card unit, the card unit connection board 314 can be omitted.

  The launch control device 312 permits or prohibits the launch of the game ball by the launch device 60, and the launch device 60 is permitted to drive when predetermined conditions are met. Specifically, a firing permission signal is output from the payout control device 311, a sensor signal is detected that the player is touching the handle 18, and a firing stop switch that stops firing is operated. On the condition that it is not done, the launching device 60 is driven, and the game ball is launched at an intensity corresponding to the operation amount of the handle 18.

  The display control device 45 executes the variable display of the decorative symbols on the decorative symbol display device 42 in accordance with an instruction from the sub-control device 262. The display control device 45 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, a video display processor (VDP) 526, an input port 527, an output port 529, and bus lines 530 and 531.

Further, a CPU 521, a program ROM 522, a work RAM 523, and a VDP 526 are connected to the input port 527 through a bus line 530. An output port 529 is connected to the VDP 526 via a bus line 531, and a decorative symbol display device 42 as a liquid crystal display device is connected to the output port 529.

  The CPU 521 of the display control device 45 receives the display command transmitted from the sub-control device 262 via the input port 527 and analyzes the received command or performs predetermined arithmetic processing based on the received command to control the VDP 526 ( Specifically, internal command generation for VDP 526 is performed. Thereby, display control in the decorative symbol display device 42 is performed.

  The program ROM 522 is a memory that stores various control programs executed by the CPU 521 and fixed value data. The work RAM 523 is a memory that temporarily stores work data and flags used when the CPU 521 executes various programs. It is.

  The video RAM 524 is a memory for storing display data to be displayed on the decorative symbol display device 42, and the display content of the decorative symbol display device 42 is changed by rewriting the content of the video RAM 524. The character ROM 525 is a memory that stores character data such as symbols displayed on the decorative symbol display device 42.

  The VDP 526 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal driving circuit) incorporated in the decorative symbol display device 42. Since the VDP 526 is an IC chip, it is also referred to as a “drawing chip”, and the substance of the VDP 526 can be said to be a microcomputer chip with a dedicated firmware for drawing processing. The VDP 526 adjusts the respective timings of the CPU 521, the video RAM 524, etc. to intervene in reading and writing data, and reads the display data stored in the video RAM 524 at a predetermined timing and causes the decorative symbol display device 42 to display it.

  The power supply device 313 includes a power supply unit 541 that supplies power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And.

  The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in AC 24 volt power supplied from the outside, generates + 12V power for driving various switches and motors, + 5V power for logic, backup power for RAM backup, etc. These + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 261, the payout control device 311 and the like. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311. Similarly, operating power is supplied to various switches, motors and the like via a control device to which these are connected.

  The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of a power failure and execute a power failure process (NMI interrupt processing).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

  The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  As described above in detail, in the present embodiment, when the box cover 263a and the box base 263b are connected, the cover-side coupling metal 435 and the base-side coupling metal 454 are disposed in the substrate box 263. The connected state cannot be released from outside the box. Further, in the connected state, the right wall portion 401e of the box cover 263a (cover body portion 401) is in contact with the right wall portion 440a of the inserted portion 440 of the box base 263b, and the main controller (main control board). The main body portion (substrate housing space) of the substrate box 263 in which the H.261 is disposed is partitioned from the coupling portion (engaging portion housing space) in which the coupling fittings 435 and 454 are disposed. For this reason, even if a wire rod or the like is caused to enter inside through a gap such as a heat radiating hole provided in the board box 263, it is practically impossible to perform the releasing operation of both the connecting metal fittings 435 and 454.

  As described above, once the substrate box 263 is in a sealed state, in order to open it, the connecting portions 430 and 450 must be cut off, leaving a trace of opening. As a result, in the case of unauthorized opening, it can be detected early and easily. As a result, it is possible to more reliably prevent a situation in which the substrate box 263 is opened so that no trace of opening remains.

  Moreover, the base side connection metal fitting 454 will be in the state penetrated between the pair of guard parts 435b of the cover side connection metal fitting 435 in the connected state. For this reason, even if a wire rod or the like is inserted into the base-side connecting portion 450, it is difficult to release the connecting brackets 435 and 454.

  Further, in the present embodiment, the cover side connection fitting 435 and the base side connection fitting 454 are provided separately from the cover side connection portion 430 and the base side connection portion 450, respectively. For this reason, even if a force is applied to the base side connection portion 450 from the outside to be distorted and the engagement between the two connection fittings 435 and 454 is attempted to be released, the distortion of the base side connection portion 450 or the like may be It becomes difficult to transmit to 454. As a result, it is possible to further enhance the above-described fraud deterrence effect.

  Furthermore, in the present embodiment, as the box cover 263a and the box base 263b are moved in the opening direction in an attempt to open the substrate box 263, the engagement between the engagement portion 435c of the cover-side connecting metal 435 and the base-side connecting metal 454 is increased. The degree of engagement with the joint portion 454c increases, making it difficult to open. As a result, it is possible to further enhance the above-described fraud deterrence effect.

  In addition, after the box cover 263a and the box base 263b are assembled, the sealing work is easier to perform and the convenience is improved as compared with a configuration in which sealing is performed using a caulking member or the like.

  Further, in the present embodiment, since both the connecting metal fittings 435 and 454 are disposed in the board box 263, a conventional structure having a sealing structure outside the board box, that is, a caulking member is inserted after the box is assembled. Compared to the sealed configuration, it may be difficult to confirm whether or not the two connection fittings 435 and 454 are properly engaged when the box is assembled, that is, whether or not the board box 263 is sealed. However, in this embodiment, since the cover side connection portion 430 and the base side connection portion 450 are formed integrally with the main body portion of the substrate box 263 from a transparent resin material or the like, the visual recognition of both the connection fittings 435 and 454 is possible. Property can be ensured, and such problems can be suppressed. As a result, early detection of fraud and the deterrence effect of fraud can be enhanced.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) The structure of the cover side connection part 430 and the base side connection part 450 is not limited to the said embodiment. For example, instead of the connection fittings 435 and 454, a resin connection member may be employed, and the portions corresponding to the first engagement portion and the second engagement portion are the cover side connection portion 430 and the base side connection portion. It is good also as a structure integrally formed in 450.

  Further, the positions where the cover-side connecting portion 430 and the base-side connecting portion 450 are formed are not limited to the above-described embodiment, and can be appropriately changed according to the assembly configuration of the box cover 263a and the box base 263b.
