As described above, pachinko gaming machines, slot machines, and the like are known as a type of gaming machine. These gaming machines are provided with a control board on which electronic components such as a CPU (Central Processing Unit) and a ROM storing a control program related to the game are mounted, and a series of games are controlled by the control board. .

In recent years, in this type of gaming machine, various illegal acts against the control board or the like have been a problem for the purpose of obtaining illegal profits. For example, numerous fraudulent acts have been reported, such as an act of opening a board box and replacing a regular control board with a separately modified control board.

Conventionally, improper measures have been taken, such as providing a sealing structure (so-called caulking structure) to the substrate box so that a history of opening due to destruction or the like is left when the substrate box is opened.

For example, a substrate box having a sealing structure includes a box base that accommodates a control board, a box cover that closes an opening of the box base, a base-side connecting portion provided on the box base, and a cover provided on the box cover. Side connection part. Then, when the box base and the box cover are assembled, the locking recess formed in the base side connecting portion and the locking hole formed in the cover side connecting portion are aligned and locked via the locking hole. The box base and the box cover are connected to each other by inserting a caulking member such as a pin with a barb into the recess.

Therefore, the caulking member inserted into the locking hole and the locking recess cannot be removed unless at least one of the base side connecting portion and the cover side connecting portion is broken (removed). That is, when the substrate box is opened, a predetermined mark is formed on the substrate box, so that if the substrate box is tampered with, it can be detected early and easily.

However, in recent years, an illegal act of removing the entire board box from the installation site of the gaming machine and replacing the board box with a separately modified version has been performed. In such a case, since the predetermined trace is not left in the newly installed illegal board box, there is a possibility that the illegal action cannot be detected early.

On the other hand, there is a gaming machine in which a counter measure against improper measures such as fixing the board box itself enclosing the control board to a predetermined installation site of the gaming machine is detachable (see, for example, Patent Document 1).

However, in the above prior art, after the board box (box base and box cover) is sealed by the caulking member, the board box must be further fixed to the predetermined installation site of the gaming machine so that it cannot be removed. In addition, there is a possibility that the labor required for the work of mounting the board box may increase.

Further, in the conventional sealing structure in which the caulking member is inserted from the outside after the box base and the box cover are assembled, the caulking member is pulled out even if the substrate box is fixed to a predetermined installation site of the gaming machine. There remains a risk of opening the box.

In addition, the said subject is a problem applicable not only to a pachinko machine but other game machines which have the same board | substrate box.

The present invention has been made to solve the above-described problems and the like, and its purpose is to improve the workability at the time of mounting the board box and to increase the deterrent effect. It is to provide a gaming machine.

And a base-side housing 472b. The cover-side housing 472a corresponds to the second bearing component in the present embodiment, and the base-side housing 472b corresponds to the first bearing component.

  Inside the bearing portion 472, when the box cover 263a and the box base 263b are connected, the housings 472a and 472b are assembled and aligned to form a hollow portion 473 that opens downward.

  When both housings 472a and 472b are assembled and aligned, a circular lower opening 473a is formed below the hollow part 473, and the upper end of the hollow part 473 has a smaller diameter than the lower opening 473a. Thus, a recess 473b having a circular cross section is formed. As a result, the hollow portion 473 functions as an insertion hole portion that rotatably supports the box shaft portion 485 as described later.

  A cover portion 810 protruding rearward is formed on the left side portion of the cover-side housing 472a along the upward direction. Thereby, the gap between the housings 472a and 472b is covered when the box cover 263a and the box base 263b are connected.

  A groove portion 811 is formed on the right side surface of the covering portion 810 along the vertical direction, and an insertion plate portion 812 is formed along the vertical direction on the left side portion of the base-side housing 472b opposite thereto. When the box cover 263a and the box base 263b are connected, the insertion plate portion 812 is inserted into the groove portion 811. Accordingly, it is possible to prevent a wire or the like from entering the hollow portion 473 from the gap between the housings 472a and 472b.

  In the cover-side housing 472a, a pair of upper and lower bosses 802 (see FIG. 21, etc.) are erected on the back side of the front wall portion 801. A metal guard formed in a box shape with respect to the boss 802. A member 474 is attached, and a metal locking fitting 476 is attached to the inside of the member 474, and these are integrally fixed by a screw 475.

  A plurality of slits for cutting 801a are intermittently provided along the periphery of the front wall portion 801 of the cover-side housing 472a. By breaking the front wall portion 801 along the cutting slit 801a, the boss 802 and thus the guard member 474 and the locking member 476 can be separated from the main body portion of the cover-side housing 472a.

  The guard member 474 is formed by bending a single metal plate. The guard member 474 faces the front wall 801 of the cover-side housing 472a and is fixed to the boss 802, and the front wall. An upper wall portion 474b, a lower wall portion 474c, a left wall portion 474d, and a right wall portion 474e extending rearward from the peripheral edge portion of the portion 474a are provided, and form a substantially box shape that opens rearward as a whole.

  The upper wall portion 474b is formed with an arc-shaped cutout portion 474f that is formed along the peripheral edge portion of the concave portion 473b of the hollow portion 473 and into which the front end of the main body portion of the box shaft portion 485 is fitted. The lower wall portion 474c is formed with an arc-shaped cutout portion 474g that is formed along the peripheral edge portion of the lower opening 473a of the hollow portion 473 and into which the base portion 485b of the box shaft portion 485 is fitted. ing.

  The locking metal fitting 476 is formed by bending a single metal plate, and extends from the lower end portion of the fixing portion 476a obliquely upward to the rear side from the fixing portion 476a fixed to the cover-side housing 472a. The folded portion 476b is formed and formed in a substantially V-shaped cross section. The locking metal fitting 476 has moderate flexibility and rigidity.

  The folding portion 476b is formed with a hole 476c into which the screw 475 is inserted when the lower screw 475 is fixed to the lower boss 802.

  Under the above configuration, in this embodiment, as shown in FIGS. 6 and 22, the board box 263 is attached to the back frame set 215 via the board mounting unit 480 so as to be opened and closed. More specifically, the back frame set 215 fixed to the back surface of the game board 30 is provided with a substantially box-shaped pedestal portion 481. 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, and a base housing 481 a that is integrally formed with the back frame set 215 and a cover housing that is assembled to the base housing 481 a by screws 482. 481b. FIG. 13 is a perspective view of a unit in which the board box 263, the board mounting unit 480, the pedestal 481 and the like are assembled together, and FIG. 14 is an exploded perspective view showing the assembling relationship. In FIGS. 13 and 14, for the sake of convenience, it is shown separated from the back frame set 215, but actually, the base housing 481 a is integrally formed with the back frame set 215 as described above. The base housing 481a is opened on the game board 30 contact surface side of the back frame set 215 due to the convenience of die cutting at the time of manufacturing the back frame set 215, and the previous stage of attaching the back frame set 215 to the game board 30 The cover housing 481b can be fixed by inserting a screw 482 inside the opening through the opening. On the other hand, when the back frame set 215 is attached to the game board 30, the opening of the base housing 481a is closed, so that the screw 482 cannot be removed and the cover housing 481b cannot be removed.

  Since both housings 481a and 481b are assembled to the pedestal portion 481, a hollow portion 483 having the same configuration as the hollow portion 473 in the bearing portion 472 is formed to open upward. Therefore, although not shown in the drawings, the same guard member and locking metal fitting as the guard member 474 and the locking metal fitting 476 are attached to the cover housing 481b.

  On the other hand, the substrate mounting unit 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.

  Each of the shaft portions 485 and 486 has a substantially columnar shape, and flange portions 485a and 486a projecting in the outer peripheral direction are formed at a substantially central portion in the longitudinal direction. 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. In addition, base portions 485b and 486b having a diameter larger than that of the main body portion are provided at the base portions of the shaft portions 485 and 486.

  Then, as described later, by inserting the box shaft portion 485 into the bearing portion 472 of the substrate box 263, the substrate box 263 is assembled to the substrate mounting unit 480 so as to be capable of relative rotational displacement.

  Similarly, the board mounting unit 480 and the board box 263 are assembled to the back frame set 215 so as to be capable of relative rotational displacement by inserting the base shaft part 486 into the base part 481 on the back frame set 215 side. It becomes.

  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 substrate mounting unit 480 and the back frame set 215 is attached to the back surface of the substrate mounting unit 480. A space for installing electrical wiring or the like is secured between the back frame set 215 and the substrate mounting unit 480. An illegal substrate can be installed using this space, or inside the pachinko machine 10 There is a possibility that an illegal act such as causing the wire or the like that has entered to come into contact with various detection switches or the like mounted on the back frame set 215 or the like through the space to cause malfunction. On the other hand, by providing the spacer 490, an extra space between the back frame set 215 and the substrate mounting unit 480 can be eliminated as much as possible, and the above-described problems can be suppressed. Further, when the substrate mounting unit 480 is fixed so as not to be rotatable because the substrate mounting unit 480 itself is provided so as to be rotatable with respect to the back frame set 215 with the pedestal shaft portion 486 as an axis. In comparison, various detection switches and relay boards mounted on the back frame set 215 can be reliably and relatively easily inspected.

  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.

  Resealing means in this embodiment is constituted by the locking pin 491, the pin holding portion 492, the locked portion 494, and the like.

  Next, an assembling procedure of the box cover 263a and the box base 263b, in which the main controller 261 is brought into the encapsulated state from the unencapsulated state where the main controller 261 is exposed, will be described with reference to FIGS. To do.

  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 (encapsulation direction), and the opposite left direction is the opening direction (encapsulation). Release 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 (encapsulated 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.

  Further, in the connected state, as shown in FIG. 16 and the like, the base side connection fitting 454 (engagement portion 454c) is arranged adjacent to the head of the screw 434 that fixes the cover side connection fitting 435. As a result, the screw 434 cannot be removed. Similarly, in the connected state, the support portion 430a of the cover side connecting portion 430 is disposed adjacent to the head of the screw 453 that fixes the base side connecting metal fitting 454. As a result, the screw 453 cannot be removed.

  Next, a procedure for attaching the substrate box 263 to the substrate mounting unit 480 as an attachment member and a procedure for attaching the substrate mounting unit 480 to the back frame set 215 as a counterpart member will be described.

  First, the box shaft portion 485 is inserted into the bearing portion 472 of the substrate box 263. When the box shaft portion 485 is inserted into the hollow portion 473 from the lower opening 473a of the bearing portion 472, the turn-up portion 476b of the locking metal fitting 476 is pushed and elastically deformed by the taper portion of the flange portion 485a (first). 1 state).

  After that, as shown in FIG. 23, the tip of the main body of the box shaft 485 is inserted into the recess 473b, and is inserted until the box shaft 485 is completely inserted into the hollow portion 473. Then, the flange portion 485a of the box shaft portion 485 passes through the folded portion 476b of the locking metal fitting 476, and the folded portion 476b returns from the elastically deformed state to the original state (second state). Thereby, the folding | returning part 476b of the latching metal fitting 476 and the collar part 485a of the axial part 485 for boxes will be in an engagement state. In this state, the box shaft portion 485 cannot be detached from the bearing portion 472, and the substrate box 263 is assembled to the substrate mounting unit 480 so as to be capable of relative rotational displacement with the box shaft portion 485 as the center. It will be. The box shaft portion 485 constitutes the mounting shaft portion in the present embodiment. Therefore, the flange portion 485a of the box shaft portion 485 constitutes an engaging portion, and the folded portion 476b of the locking metal fitting 476 constitutes an engaged portion (locking piece).

  When the insertion of the box shaft portion 485 is completed, the peripheral edge of the lower opening 473a of the hollow portion 473 of the bearing portion 472 and the outer peripheral portion of the base portion 485b of the box shaft portion 485 are in contact with each other with almost no gap. . Further, the outer peripheral portion at the front end of the main body portion of the box shaft portion 485 and the inner peripheral portion of the concave portion 473b of the hollow portion 473 are in contact with each other with almost no gap. Thereby, the rotation operation of the substrate box 263 can be stabilized. At the same time, a wire or the like is caused to enter the hollow portion 473 through the gap between the lower opening 473a and the box shaft portion 485, and the folding portion 476b of the locking metal fitting 476 is disengaged, so that the substrate box 263 is moved to the box shaft. Unauthorized acts such as removal from the unit 485 can be prevented.

  Further, the peripheral edge of the notch 474f of the upper wall part 474b of the guard member 474 and the outer peripheral part of the front end of the main body part of the box shaft part 485 are in contact with each other with almost no gap, and the notch part 474g of the lower wall part 474c. The peripheral edge and the base 485b of the box shaft 485 are in contact with each other with almost no gap. Further, the rear end edge portions of the left wall portion 474d and the right wall portion 474e of the guard member 474 are in contact with the base-side housing 472b with almost no gap. As a result, the engagement portion between the flange portion 485a of the box shaft portion 485 and the folded-back portion 476b of the locking metal fitting 476 is covered with the guard member 474, so that the wire rod enters the hollow portion 473 from the cutting slit 801a. As a matter of course, even if a hole is made in the side wall of the bearing portion 472 and a wire rod or the like enters the hollow portion 473, the folding portion 476b of the locking metal fitting 476 is released. It becomes difficult. That is, an illegal act of removing the board box 263 from the box shaft portion 485 can be prevented. In addition, since it is difficult to visually recognize the engagement portion, it is difficult to perform an unauthorized engagement release operation. Since the bearing portion 472 is formed of a transparent resin material or the like together with the main body portion of the substrate box 263, the effect is high. The guard member 474 constitutes the covering means in this embodiment.

  When the attachment of the substrate box 263 to the box shaft portion 485 is completed, the substrate box 263 is subsequently rotated and displaced in a direction approaching the plate portion 480a of the substrate mounting unit 480, and the locking claw 487 of the plate portion 480a is moved to the substrate box. 263 is locked to the locked portion 488 of the H.263. As a result, the substrate box 263 is fixed to the plate portion 480a, and upward movement, which is movement in the removal direction of the substrate box 263, is restricted. Therefore, the disengagement prevention means in the present embodiment is constituted by the locking claws 487 of the plate portion 480a.

  Next, the board mounting unit 480 integrated with the board box 263 is attached to the back frame set 215. Specifically, by inserting the pedestal shaft portion 486 of the board mounting unit 480 into the pedestal portion 481 on the back frame set 215 side, the pedestal shaft portion 486 becomes the pedestal portion as in the case of the box shaft portion 485. The board mounting unit 480 is assembled to the back frame set 215 so as to be capable of relative rotational displacement with the pedestal shaft portion 486 as the center.

  As described above, in the present embodiment, in the closed state of the inner frame 12, the rotation operation of the board box 263 is regulated by the back pack unit 203, and the rotation operation of the back pack unit 203 is further performed on the outer frame 11. Since it is regulated by the extending wall portion 83, the board box 263 cannot be removed. Therefore, the rotation restricting means in the present embodiment is configured by the back pack unit 203, the extending wall portion 83, and the like.

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

  First, with the back pack unit 203 opened, the connector cover 412 is removed from the board box 263 by breaking or the like, and then the plug-in side connectors of various cables electrically connected to the dispensing control device 311 and the like are connected. Remove from the receiving connector of the main controller 261.

  Next, the tip of a tool such as a nipper or a cutter is inserted into the cutting slit 801a of the front wall 801 of the cover-side housing 472a, and the portion between the adjacent cutting slits 801a is cut. As a result of this work, as shown in FIG. 24, a portion of the front wall 801 on the inner peripheral side of the cutting slit 801a (hereinafter simply referred to as the front wall 801) is separated from the main body of the cover-side housing 472a. By separating the front wall portion 801, the boss 802 provided on the front wall portion 801, and the guard member 474 and the locking metal fitting 476 attached thereto can be removed at the same time.

  When the locking bracket 476 is removed, the engagement between the folded portion 476b of the locking bracket 476 and the flange portion 485a of the box shaft portion 485 is released.

  In this state, the latching claw 487 of the plate portion 480a is removed from the latched portion 488 of the substrate box 263, and the substrate box 263 is rotationally displaced in a direction away from the plate portion 480a, and then lifted upward. The board box 263 can be removed from the board mounting unit 480.

  As described above, once the substrate box 263 is removed from the substrate mounting unit 480, the removed trace, that is, the trace of the front wall 801 being cut off remains on the substrate box 263 side. Further, since the locking metal fitting 476 is cut off at the same time, the board box 263 cannot be attached to the box shaft portion 485 in the original state again.

  Then, after removing the substrate box 263 from the substrate mounting unit 480, the substrate box 263 is opened.

  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, after inserting the tip of a tool such as a cutter into the cover-side plate-like portion 461, the base-side plate-like portion 463, and the boundary portion, and tearing the seal seal 470, the screws 465 are removed from the plate-like portions 461 and 463. Thus, the substrate box 263 can be opened.

  Next, a description will be given of an operation of sealing again when the opened substrate box 263 is delivered to an inspection organization or the like.

  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 inserted into the locking hole 494a (see FIG. 21 and the like) of the locked portion 494 on the box base 263b side and locked. 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

  Next, the electrical configuration of the pachinko machine 10 will be described. FIG. 25 is a block diagram showing an electrical configuration of the pachinko machine 10. The main controller 261 (main board) of the pachinko machine 10 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic unit. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a RAM 503 that is a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. Various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated. However, the CPU, the ROM, and the RAM may not be integrated into one chip but may be configured as a chip for each function.

  The RAM 503 is a stack area that stores the contents of the internal registers of the CPU 501, the return address of a control program executed by the CPU 501, and a work area (work area) that stores various flags, counters, I / O values, and the like. ) And a backup area 503a.

  The RAM 503 is configured to retain (backup) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, and is stored in the stack area, work area, and backup area 503a. All data is backed up.

  In the backup area 503a, when the power is cut off due to a power failure or the like, the power of the pachinko machine 10 is restored to the state before the power is turned off when the power is turned on again. (Similarly) is an area for storing stack pointers, values of registers, I / O, and the like. Writing to the backup area 503a is executed when the power is turned off by the main process. Conversely, the return of each value written to the backup area 503a is the main process at the time of power-on (including power-on due to power failure cancellation, and so on). Executed in Note that a power failure signal SK1 output from a power failure monitoring circuit 542, which will be described later, is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 501 when a power failure occurs due to the occurrence of a power failure or the like. Due to the occurrence, the power failure process (NMI interrupt process) is immediately executed.

  Note that if data stored in at least the stack area and the backup area 503a 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 503a may be backed up, and the data stored in the work area may not be backed up.

  An input / output port 505 is connected to the CPU 501 incorporating the ROM 502 and RAM 503 via a bus line 504 including an address bus and a data bus. A RAM erase switch circuit 543, a payout control device 311, a sub control device 262, a special display device 43, a normal symbol display device 41, etc., which will be described later, are connected to the input / output port 505. With this configuration, the special display device 43 and the normal symbol display device 41 described above are directly controlled by the main control device 261. On the other hand, the decorative symbol display device 42 is controlled via the sub-control device 262.

  In addition, for convenience, illustration of various relay boards and the like is omitted, but the input / output port 505 includes a prize opening switch 221, a count switch 223, first opportunity corresponding unit switches 224a and 224b, a second opportunity corresponding opening switch 225, and the like. Various detection switches and various electrical components such as various substrates are connected. That is, the main controller 261 is provided with a plurality of terminal portions (board side connectors) for connecting connectors of various cable connectors, and the input / output port 505 is configured by these terminal portions.

  The sub-control device 262 (sub-control board) includes a CPU 551 that is an arithmetic unit, various control programs executed by the CPU 551, a ROM 552 that stores fixed value data, and various control programs that are stored in the ROM 552. In addition to a RAM 553 that is a memory for temporarily storing data, an input / output port 554, a bus line 555, various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit (not shown) are also provided. The RAM 553 is a memory that temporarily stores work data and flags used when the CPU 551 executes various programs.

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, the substrate box 263 is attached to the substrate mounting unit 480 so as to be capable of rotational displacement. Thereby, the inspection work etc. of the back side of substrate box 263 can be performed easily. As a result, convenience during maintenance can be improved. Further, even if an unauthorized circuit board or the like is attached to the back side of the substrate box 263, the unauthorized act can be detected early at the time of maintenance or the like, and the effect of suppressing the unauthorized act can be enhanced.

  Further, since the substrate box 263 can be rotated and displaced, the connecting portions 430 and 450 as sealing means provided on the free end side opposite to the rotation axis side of the substrate box 263 and the sealing seal 470 are provided. The inspection work in the state can be performed at a position closer to the worker. As a result, it is easy to check these various sealing means, and it is possible to check the presence of unauthorized opening more finely. In addition, the ID information stored in the IC chip of the seal sticker 470 can be read more efficiently with a scanner or the like.

  Further, when the board box 263 is attached, the work is completed by simply inserting the box shaft part 485 of the board mounting unit 480 into the bearing part 472 of the board box 263 without requiring a special tool. . That is, the substrate box 263 can be attached to the substrate mounting unit 480 with one touch.

  Moreover, simply by attaching, the folded portion 476b of the locking metal fitting 476 and the flange portion 485a of the box shaft portion 485 are engaged in the bearing portion 472, and the board box 263 cannot be removed from the board mounting unit 480. Therefore, it is excellent in the convenience regarding the disabling operation.

  Similarly, when the board mounting unit 480 is detachably attached to the back frame set 215, the legitimate board box 263 is illegally removed, and the whole board box 263 with the illegal main controller 261 is replaced. Cheating can be deterred.

  In the present embodiment, the housings 472a and 472b constituting the bearing portion 472 are assembled by slidably displacing and connecting (sealing) the box cover 263a and the box base 263b. The two housings 472a and 472b are assembled and aligned to form a hollow portion 473 having an internal shape into which the box shaft portion 485 can be inserted. That is, when the box cover 263a and the box base 263b are not connected (encapsulated) and the main controller 261 is not completely encapsulated by the substrate box 263, the substrate box 263 is used for the box. It cannot be attached to the shaft portion 485. Thereby, it is possible to confirm whether or not the board box 263 is completely closed when the board box 263 is attached to the board mounting unit 480. As a result, it is possible to prevent a situation in which the substrate box 263 is left as it is despite being not completely closed.

  Conversely, in a state where the box shaft portion 485 is inserted into the bearing portion 472, the movement of the box cover 263a and the box base 263b in the opening direction is restricted by the box shaft portion 485. That is, in the state where the substrate box 263 is attached to the substrate mounting unit 480, the substrate box 263 cannot be opened, and the effect of preventing unauthorized use can be further improved.

  As a result, in this embodiment, the sealing operation for making the substrate box 263 unopenable and the operation for attaching the substrate box 263 can be performed with one touch without using a special tool. Thereby, while simplifying the attachment operation | work of the board | substrate box 263, the illegal act of opening or removing the board | substrate box 263 illegally can be suppressed.

  In the present embodiment, the restricting means for restricting the relative movement of the box cover 263a and the box base 263b in the opening direction is the box shaft portion 485, so that the substrate box 263 is installed in a predetermined manner like a conventional caulking member. There is little possibility that only the caulking member is pulled out from the outside while being fixed to the site.

  Furthermore, in this embodiment, the movement of the substrate box 263 in the removal direction is restricted by the locking claws 487 of the plate portion 480a of the substrate mounting unit 480. In addition, in the closed state of the inner frame 12, the rotation operation of the substrate box 263 is regulated by the back pack unit 203, and the rotation operation of the back pack unit 203 is further regulated by the extending wall portion 83 of the outer frame 11. It becomes the composition which is done. As a result, even if the engagement between the locking metal fitting 476 and the box shaft portion 485 is released to perform a fraudulent act, the fraudulent person first opens the inner frame 12, then opens the back pack unit 203, Furthermore, the board box 263 cannot be removed and opened unless a complicated process such as opening the board box 263 is performed. As a result, the deterrent effect of removing the board box 263 can be further enhanced.

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

  (A) In the above embodiment, the cover side connecting portion 430 and the base side connecting portion 450 that are connected without using a connecting member such as a caulking pin are employed as the main sealing means for sealing the substrate box 263. The configuration of the means is not limited to the above embodiment. For example, a configuration in which the box base 263b and the box cover 263a are connected via a connecting member such as a caulking pin or a breaking screw and the substrate box 263 is sealed may be employed.

  In addition, when the board box 263 is attached, a configuration in which movement of the box base 263b and the box cover 263a in the opening direction is restricted by the box shaft portion 485 inserted into the bearing portion 472 may be employed as the sealing means. Good. In this way, other sealing means such as the cover side connecting portion 430 and the base side connecting portion 450 can be omitted, and the number of parts can be reduced and the configuration can be simplified.

  (B) In the above-described embodiment, the box cover 263a and the box base 263b are slid in the left-right direction so that both are assembled. For example, the box cover 263a and the box base 263b are assembled by being relatively displaced in the vertical direction, the box cover 263a and the box base 263b are assembled by pressing the box cover 263 back and forth, or the box base 263b. On the other hand, it is good also as a structure assembled | attached by rotating after pivotally supporting the one side part side of the box cover 263a.

  (C) In the above embodiment, the substrate box 263 is attached to the back frame set 215 so as to be rotatable and unremovable via the substrate mounting unit 480. However, the present invention is not limited to this, and the substrate mounting unit 480 is not limited thereto. The substrate box 263 may be directly attached to the back frame set 215.

  The substrate box 263 and the substrate mounting unit 480 are not necessarily provided so as to be rotatable. For example, the substrate box 263 may be fixed to the substrate mounting unit 480 so as not to rotate. The mounting unit 480 may be fixed to the back frame set 215 so as not to rotate.

  In the above embodiment, the substrate box 263 and the substrate mounting unit 480 are mounted with the vertical direction as the mounting direction (rotation axis). However, the present invention is not limited thereto, and the mounting direction (rotation axis) is, for example, You may employ | adopt the structure which attaches the board | substrate box 263 grade | etc., So that it may become the left-right direction.

  For example, as shown in FIG. 26, the cover side connecting portion 430, the base side connecting portion 450, the seal seal 470 and the like are omitted from the right side portion of the substrate box 263, and bearing portions 472 are provided on both the left and right sides of the substrate box 263. In addition to the configuration, a pair of box shaft portions 485 may be formed to protrude from the back frame set 215 correspondingly. Thereby, the board | substrate box 263 can be fixed to the back frame set 215 so that it cannot be removed and cannot be opened.

  In addition, as shown in FIG. 27, a total of four box shafts 485, two each on the left and right sides, are formed so as to protrude rearward from the back frame set 215, and a bearing portion 849 opened forward so that these can be inserted is formed. A configuration may be adopted in which two are provided on each of the left and right side surfaces of the substrate box 263.

  (D) In the above embodiment, the movement of the substrate box 263 in the removal direction is restricted by the locking claws 487 of the plate portion 480a of the substrate mounting unit 480. However, the present invention is not limited to this, and a configuration in which the removal preventing means such as the locking claw 487 is omitted may be employed. Further, for example, after the board box 263 is mounted, a configuration that restricts the movement of the board box 263 in the removal direction by another device by attaching the display control device 45 or the like to the upper position of the board box 263 is employed as a removal prevention means. May be.

  (E) The shape, configuration, dimensions, number, and the like of the box shaft portion 485 and the bearing portion 472 are not limited to the above embodiment, and can be changed as appropriate.

  For example, a configuration in which a mounting shaft portion is provided on the substrate box 263 side and a bearing portion is provided on the substrate mounting unit 480 side may be employed. In other words, the box cover 263a or the box base 263b is provided with the first attachment shaft portion constituting portion or the second attachment shaft portion constituting portion, and the both attachment shaft portion constituting portions are aligned to form a predetermined attachment shaft portion. It is good also as a structure.

  Further, for example, the bearing portion 472 in the above-described embodiment has a halved structure including a cover-side housing 472a and a base-side housing 472b that are divided into two in the front-rear direction. In this way, a configuration may be adopted in which the bearing portion 850 is composed of an upper cover side housing 850a and a lower base side housing 850b, which are divided into two vertically. In this case, when the box cover 263a and the box base 263b are connected, the insertion recess 851 formed in the upper cover side housing 850a and the insertion hole 852 formed in the lower base side housing 850b are aligned. A configuration may be employed in which the box shaft portion 485 is inserted into the insertion recess 851 via the insertion hole 852 and locked.

  In the above embodiment, the cutting slit 801a is formed along the periphery of the front wall portion 801 of the bearing portion 472. However, the present invention is not limited to this, and the cutting slit 801a may be omitted from the bearing portion 472. Good. Or it is good also as a structure which replaced with the slit 801a for a cut | disconnection and provided the thin part along the circumference | surroundings of the front wall part 801. FIG. In this way, it is not necessary to form a through hole that communicates with the inside of the bearing portion 472, so that the fraud prevention effect is enhanced. In such a case, a configuration in which the guard member 474 is omitted may be employed.

  (F) Not only the substrate box 263 that accommodates the main control device 261 but also the substrate box that accommodates other control devices may have the same configuration as the substrate box 263.

  (G) You may implement as a pachinko machine of a different type from the above-mentioned embodiment. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball similar thereto may be used. Further, as a gaming machine other than a pachinko machine, it can of course be implemented as a slot machine as a swivel type gaming machine or a gaming machine in which a pachinko machine and a slot machine are integrated.

  Hereinafter, the technical idea that is not described in the claims and that can be grasped from the above embodiment will be described together with the effects thereof.

Means 1. A gaming machine comprising a control board for performing predetermined control related to a game, and a board box for enclosing the control board,
The board box is
It consists of a first box component and a second box component,
By relatively moving the first box component and the second box component in a predetermined encapsulation direction, the control board is encapsulated,
From the encapsulated state, the encapsulated state is released by relatively moving the first box constituting member and the second box constituting member in an encapsulating release direction that is opposite to the encapsulating direction. It is a configuration that is in an encapsulated release state,
When the first box component and the second box component are in the encapsulated state, a first bearing component or a first mounting shaft component integrally formed with the first box component, The second bearing component or the second mounting shaft component integrally formed with the second box component is aligned to form a predetermined bearing or mounting shaft,
The mounting shaft provided on one side of the board box or the counterpart member to which the board box is attached is in the enveloping direction with respect to the insertion hole of the bearing provided on the other corresponding to the mounting shaft. And by inserting in a direction (orthogonal or substantially orthogonal direction) intersecting the encapsulation release direction,
The engaging portion provided in the mounting shaft portion and the engaged portion provided in the insertion hole portion are engaged,
The board box is detachably attached to the counterpart member, and the attachment box portion or the bearing portion provided on the counterpart member allows the first box constituent member and the second box constituent member to A gaming machine characterized in that relative movement is restricted in the enveloping release direction.

  Note that “unremovable” means that unless a predetermined trace is left by, for example, destroying at least one of the attachment shaft portion or the bearing portion, the two cannot be separated. Therefore, in a state where the substrate box is attached to the counterpart member, the substrate box cannot be removed from the counterpart member unless the bearing portion is cut or the like. I can't even do that. When the substrate box is removed, a predetermined mark is formed on the bearing portion or the like, so that if it is illegally opened, it can be detected early and easily.

  That is, according to the above means 1, the sealing operation for making the substrate box unopenable and the operation for attaching the substrate box to the counterpart member can be performed with one touch without using a special tool. As a result, it is possible to simplify the mounting operation of the board box, and to suppress illegal actions such as illegally opening or removing the board box. As a result, since the conventional sealing structure for sealing the board box can be omitted, the configuration of the board box can be simplified and the number of parts can be reduced.

  Further, in this means, since the restricting means for restricting the relative movement in the encapsulating release direction of both box constituent members is the mounting shaft portion or the bearing portion provided in the counterpart member, like the conventional caulking member, There is little possibility that only the caulking member is pulled out from the outside while the board box is fixed to the predetermined installation site of the gaming machine.

  As a specific configuration example of the engaging portion of the mounting shaft portion and the engaged portion of the bearing portion, for example, “the engaged portion is a first that allows passage of the mounting shaft portion (engaging portion)”. A disengageable locking piece in a state and a second state that restricts movement of the mounting shaft portion (engagement portion) in the removal direction, and the mounting shaft portion is inserted into the insertion hole portion of the bearing portion. By inserting, after the locking piece in the first state is pressed by the engaging portion and becomes the second state, the engaging portion passes through the locking piece, A configuration in which the locking piece is returned to the first state by its own elastic force and the engaging portion engages with the locking piece is exemplified.

  The “mounting hole portion” is preferably a non-penetrating “concave portion” from the viewpoint of preventing fraud, but is not limited to this, and makes it difficult for a wire or the like to enter the bearing portion. If it is configured, it may be formed as a penetrating “hole”.

  Mean 2. The first box component and the second box component are in the encapsulated state, and the first bearing component or first attachment shaft component and the second bearing component or second attachment shaft component. In the means 1, the insertion shaft portion into which the mounting shaft portion can be inserted or the mounting shaft portion into which the insertion shaft portion can be inserted into the insertion hole portion is formed. The gaming machine described.

  According to the means 2, when the first box component and the second box component are not encapsulated, that is, when the control board is not completely encapsulated by the substrate box, the substrate box Cannot be attached to the mounting shaft or bearing. Thereby, it can be confirmed whether or not the substrate box is completely closed. As a result, it is possible to prevent the substrate box from being left as it is despite being not completely closed.

  Means 3. The gaming machine according to claim 1 or 2, further comprising a resealing means capable of sealing the board box after removing the board box from the counterpart member in a state where a predetermined mark is left.

  According to the above means 3, even if the substrate box is removed from the counterpart member by opening the bearing portion or the mounting shaft portion, etc., the substrate is reopened using the resealing means of this means. The box can be sealed. As a result, for example, when a failed control board is handed over to an inspection organization or the like, a situation in which the control board is damaged during transportation or a situation in which the control board is replaced with an unauthorized control board during transportation is prevented. Can do.

  Means 4. The gaming machine according to any one of means 1 to 3, wherein the bearing portion is configured so that the engaged portion can be excised from the main body portion.

  According to the means 4, the engaged state between the engaging portion of the mounting shaft portion and the engaged portion of the bearing portion can be released by separating the engaged portion from the main body portion, and the board box is removed. It is possible to improve workability when performing work.

  If the entire bearing part is separated from the board box or the mating member, the bearing part is left in a state where it cannot be removed from the mounting shaft part. When the bearing portion is provided, a new substrate box cannot be attached after the substrate box is removed, so that the recyclability may be lowered. In this respect, according to the present means, it is possible to prevent such a problem from occurring.

  As a specific configuration capable of excising the engaged portion, for example, a configuration in which a plurality of excision slits are intermittently formed so as to surround a predetermined portion of the bearing portion provided with the engaged portion is an example. It is mentioned in. In such a case, the engaged portion can be excised by inserting the tip of a tool such as a nipper or cutter into the excision slit and cutting a portion between adjacent excision slits.

  Further, once the board box is removed from the mounting shaft portion, the engaged portion is cut off from the bearing portion, so that the board box cannot be attached to the mounting shaft portion in the original state again. Thus, if an illegal act of removing the board box is performed, the illegal act can be detected early.

  Means 5. The gaming machine according to any one of means 1 to means 4, wherein a covering means for covering the engaging portion, the engaged portion and the engaging portion is provided in the insertion hole portion of the bearing portion.

  According to the above means 5, by providing the covering means, even if a hole is made in the bearing portion and a wire rod or the like is inserted into the bearing portion, the engagement portion and the engaged portion are disengaged. It becomes difficult. In addition, since it is difficult to visually recognize the engagement portion, it is difficult to perform an unauthorized engagement release operation. Usually, since the substrate box is formed of a transparent resin material or the like, the effect is high.

  In order to improve convenience, when a slit for excision as described above is provided, it is possible to allow a wire or the like to enter the bearing portion through the slit.
