The screw 442 used for fixing the restricting piece 441 is a general screw (for example, a wood screw) formed with a cross hole or a slit, and the restricting piece 441 is detachable.

  As shown in FIG. 8 and the like, the box cover 263b has a substantially box shape that opens to the left side (box base 263a side) in the rear view of the pachinko machine 10, and the opening 402 of the box base 263a in the assembled state of the substrate box 263. A cover 451 for closing the cover, a cover side connecting portion 453 provided along an opening (hereinafter referred to as a cover side opening 452) of the lid 451, and the box base 263a side (of the pachinko machine 10) from the lid 451 And a pair of upper and lower holding portions 455 extending leftward in the rear view).

  The cover-side connecting portion 453 includes a frame-like base portion 461 extending from the inner peripheral side portion of the cover-side opening portion 452 to the box base 263a side of the edge on the cover-side opening portion 452 side of the lid portion 451, and a base portion 461. The engaging piece 462 protrudes from the portion excluding the corner portion to the box base 263a side, and the engaging claw 463 protrudes from the distal end portion of the engaging piece 462 toward the outer peripheral side of the cover side opening 452. . Since the engagement piece 462 is not continuous in the circumferential direction of the cover side opening 452 and is interrupted corresponding to each corner portion of the base portion 461, the cover side opening portion with respect to the engagement piece 462 is provided. When stress is applied to the inner peripheral side of 452, it bends slightly. On the other hand, the frame-shaped base portion 461 is hardly deformed even when stress is applied, and it is difficult or impossible to bend the engagement piece 462 even if a force is applied to the base portion 461. It has become.

  As shown in FIGS. 9A and 9B, the engaging claw 463 is configured so that the left side surface (left side in FIG. 9) of the pachinko machine 10 faces the inner peripheral side of the cover side opening 452. The surface on the right side of the pachinko machine 10 is extended in a direction orthogonal to the engagement piece 462 (base 461). In addition, in the inner and outer peripheral directions of the cover side opening 452, the front end portion of the engagement claw 463 (the end portion on the outer peripheral side of the cover side opening 452) is closer to the cover side opening 452 than the outer peripheral surface of the lid 451. Located on the inner circumference.

  Further, as described above, the base 461 extends from the inner peripheral side portion of the cover side opening 452 out of the edge on the cover side opening 452 side of the lid 451, and therefore the outer peripheral surface of the base 461 is It is located on the inner peripheral side of the cover side opening 452 with respect to the outer peripheral surface of the lid 451, and a step is formed at the boundary between them. Accordingly, the container portion having a U-shaped cross section is formed by the surface on the box base 263a side of the lid portion 451, the surface on the outer peripheral side of the cover side opening 452 of the base portion 461, and the surface on the lid portion 451 side of the engaging claw 463. 464 is formed.

  In the present embodiment, the locking member 431 is fitted into the housing portion 464, and the box base body 401 and the box cover 263b are aligned (the contact wall portion 431a of the locking member 431 and the box base body 401 are aligned). In a state in which the edge of the engaging portion 431 is in contact with the opening 402 side), the concave portion 434 of the engaging member 431 is filled and cured with a photocurable resin, and the curable property that connects the engaging member 431 and the box base body 401 is connected. A resin layer 432 is formed. That is, the locking member 431 connected to the box base main body 401 by the curable resin layer 432 and the engaging claw 463 of the cover side connecting portion 453 are brought into an engaged state, whereby the base side connecting portion 403 and the cover side are engaged. The connecting portion 453 is engaged (connected), and the substrate box 263 is sealed (the main controller 261 is sealed). In addition, since the locking member 431 is fitted in the accommodating portion 464, a gap between the base side connecting portion 403 and the cover side connecting portion 453 can be eliminated, and the base side connecting portion 403 and the cover side connecting portion can be eliminated. Unauthorized acts such as a wire rod or the like entering the inside of the board box 263 from between the parts 453 can be prevented. In this embodiment, in order to accommodate the knob portion 436 between the edge on the opening 402 side of the box base main body 401 and the lid portion 451, the base side of the edge on the box base 263 a side of the lid portion 451. The part corresponding to the knob part 436 provided in the connecting part 403 is located on the side farther from the box base 263a (the right side in FIG. 9) than the other parts (not shown).

  In addition, the lateral width of the accommodating portion 464 (the distance between the engaging claw 463 and the lid portion 451) is configured to be the same as the lateral width of the locking member 431. Accordingly, when the locking member 431 is connected to the box base main body 401, the locking member 431 can be temporarily fixed to the box cover 263b, and workability can be improved.

In addition, since the locking member 431 is made of a flexible material, the locking member 431 can be securely fitted to the housing portion 464 and is bent corresponding to the corner portion. In such a case, it can be deformed in a follow-up manner, and a situation in which the locking member 431 is lifted from the base 461 at the corner can be suppressed. Note that the lateral width of the accommodating portion 464 may be slightly smaller than the lateral width of the locking member 431. Even in the case of adopting this configuration, since the curable resin layer 432 is not formed in the concave portion 434 of the locking member 431 at the stage of fitting the locking member 431 into the housing portion 464, the locking member 431 is It can be fitted so as to be compressed.

Further, as shown in FIGS. 9A and 9B, the bottom surface of the recess 434 of the locking member 431 fitted in the housing portion 464 is the tip of the engaging claw 463 (the outer peripheral side of the cover side opening 452). It is located on the inner peripheral side of the cover side opening 452 from the end). As a result, the engagement claw 463 and the curable resin layer 432 partially overlap in the direction in which the box cover 263b is attached to or detached from the box base 263a, and when the box cover 263b is pulled away from the box base 263a. The stress acts reliably on the curable resin layer 432. Therefore, when the box cover 263b is forcibly pulled and removed from the box base 263a, the curable resin layer 432 is broken. In other words, the substrate box 263 cannot be opened unless the curable resin layer 432 is broken. In particular, in the present embodiment, as described above, the thickness of the portion of the curable resin layer 432 corresponding to the boundary portion between the locking member 431 and the box base body 401 is thin, and stress is applied to the boundary portion. It is the composition which concentrates. Therefore, as described above, when the substrate box 263 is forcibly opened, the thin-walled portion is broken, and the base-side connecting portion 403 is separated from the box base 263a.

  In addition, the corner portion of the locking member 431 on the box cover 263b side and the inner peripheral side of the opening 402 has a shape cut obliquely. For this reason, when the knob part 436 is pinched and the base side connecting part 403 is pulled, the locking member 431 can easily come out of the housing part 464, and the base side connecting part 403 can be easily removed from the box base body 401. Yes.

  As shown in FIG. 8, the pair of upper and lower holding portions 455 are formed to extend from the corner portion of the upper side portion and the front side portion of the base portion 461 and the corner portion of the lower side portion and the front side portion toward the box base 263a. When the board box 263 is assembled, it is housed inside the box base body 401. The holding portions 455 are each configured to have a substantially U-shaped cross section, and the upper side portion and the lower side portion of the main controller 261 are inserted into the holding portions 455, respectively. As a result, the main controller 261 is held by the pair of upper and lower holding portions 455. Therefore, for example, by removing the box cover 263b from the box base 263a, the main control device 261 held by the holding portion 455 is taken out from the box base 263a as the box cover 263b is displaced. For this reason, it is possible to improve the workability when the main cover 261b is removed and the main controller 261 is taken out (accommodated again after being taken out) with the box base 263a attached to the back frame set 215. . In addition, a fixing means for fixing the holding portion 455 and the main control device 261 is provided (for example, a screw hole is formed at an intermediate position in the longitudinal direction of the holding portion 455 and the main control device 261 is inserted into the holding portion 455. It is also possible to form a fixing hole that is aligned with the screw hole in the state and screw the screw into the screw hole and the fixing hole).

  Further, as shown in FIG. 10, the box base body 401 protrudes from the upper wall portion and the lower wall portion of the box base body 401 to the inside of the box base body 401 corresponding to the upper and lower holding portions 455, A pair of upper and lower support plate portions 471 that respectively support the rear surfaces of the holding portions 455 are provided. In the assembled state of the substrate box 263, the upper holding portion 455 is substantially in contact with the front wall portion, the upper wall portion, and the support plate portion 471 protruding from the upper wall portion of the box base body 401, The side holding portion 455 is substantially in contact with the front wall portion, the lower wall portion, and the support plate portion 471 protruding from the lower wall portion of the box base body 401. Thereby, the main controller 261 and the box cover 263b are positioned with respect to the box base 263a. In the present embodiment, the front wall portion, the upper wall portion, the lower wall portion, and the support plate portion 471 of the box base body 401 that supports the outer peripheral surface of the holding portion 455 when the main controller 261 is inserted into the box base body 401. The holding unit 455 constitutes a positioning means. Further, when the box base 263a and the box cover 263b are assembled, the holding portion 455 is in sliding contact with the support plate portion 471 and the like, so that the insertion of the main controller 261 is guided, and the holding portion 455 is connected to the box base main body 401. In the state accommodated inside the box cover 263b, the box cover 263b does not fall off from the box base 263a even if both the box base 263a and the box cover 263b are not supported. Accordingly, it is possible to improve the workability when the board box 263 is assembled (sealed).

  Here, the sealing operation (first sealing) of the substrate box 263 will be briefly described. First, the upper side and the lower side of the main control device 261 are inserted inside the pair of upper and lower holding portions 455 of the box cover 263b so that the main control device 261 is held by the box cover 263b. Next, the locking member 431 is fitted into the accommodating portion 464 of the cover side connecting portion 453 along the circumferential direction of the cover side opening 452. Further, the holding portion 455 is inserted between the front wall portion of the box base body 401 and the support plate portion 471 until the base side connecting portion 403 and the cover side connecting portion 453 come into contact with each other in a non-engaged state. The main controller 261 is inserted inside the box base 263a (until the inclined surfaces of the connecting portions 403 and 453 come into contact). As a result, the locking member 431 and the box base main body 401 are brought into contact with each other, and the opening 402 of the box base main body 401 is closed by the lid 451 (see FIG. 9A).

  Next, in the state where the box base main body 401 and the box cover 263b are aligned as described above, the concave portion 434 of the locking member 431 and the filling portion 423 of the box base main body 401 are filled with a photocurable resin and cured. By doing so, the curable resin layer 432 is formed. In this way, the curable resin layer 432 is formed between the locking member 431 and the box base main body 401, whereby the locking member 431 and the box base main body 401 are coupled (the base with respect to the box base main body 401). Side connection portion 403 is formed by connection). Further, since the locking member 431 is in a state of being fitted into the accommodating portion 464, that is, in a state of being locked to the cover side connecting portion 453, the locking member 431 and the box base body 401 are connected. Thus, the base side connecting portion 403 and the cover side connecting portion 453 are connected. Accordingly, as shown in FIGS. 7 and 9A, the box base 263a and the box cover 263b are connected (the substrate box 263 is caulked), and the main controller 261 is sealed. In the present embodiment, the base side connecting portion 403 and the cover side connecting portion 453 correspond to the first sealing means.

  Thereafter, by attaching the restricting piece 441 to the box base main body 401, the sealing operation of the substrate box 263 is completed. In the present embodiment, prior to the sealing operation, out of the four mounting holes 412 formed in the rear wall portion 404 of the box base body 401, the second mounting hole 412 from the left in the rear view of the pachinko machine 10 is formed. On the other hand, the break screw 418 is screwed, and the panel member 416 is attached to the slide rail 415 (to be inserted), and the break screw 418 is attached to the rightmost mounting hole 412 among the four mounting holes 412. Screw it on. Thus, in the connected (engaged) state of the base side connecting portion 403 and the cover side connecting portion 453 (sealed state of the substrate box 263 by the first sealing means), the receiving side connector 265 mounted on the main controller 261 The positions of the panel member 416 and the connection hole 417 coincide with each other, and the receiving side connector 265 and the insertion side connector can be reliably connected.

  Next, in the game hall, the work of opening the board box 263 and inspecting or replacing the main controller 261 without removing the box base 263a from the pachinko machine 10 (back frame set 215) will be briefly described. .

  First, the insertion-side connector is removed from the receiving-side connector 265 and the restriction piece 441 is removed from the box base body 401. Subsequently, the knob portion 436 of the base side connecting portion 403 is pinched and pulled. By this work, the curable resin layer 432 (the portion of the curable resin layer 432 near the boundary between the locking member 431 and the box base body 401) is broken, and the base side connecting portion 403 is removed from the substrate box 263. Is done. By removing the base side connecting portion 403, the connection state (sealed state) between the box base 263a and the box cover 263b is released.

  Then, the holding portion 455 is extracted from the box base main body 401, the box cover 263b is removed from the box base 263a, and the main controller 261 is taken out.

  After the main control device 261 has been inspected or replaced, when the substrate box 263 is sealed again (second time sealing), as in the case of the first time sealing, the main box The control device 261 is inserted inside the box base main body 401. However, in this work, the box cover 263b is pressed against the box base main body 401 even after the engaging portion 421 and the cover side engaging portion 421 contact each other in a non-engaged state. That is, as shown in FIG. 9B, the end of the box base body 401 on the opening 402 side is filled so as to fill the space formed by removing the base side connecting portion 403 (locking member 431). The box cover 263b is pushed into the box base 263a until the edge comes into contact with the lid portion 451. By this operation, the engaging portion 421 and the cover side connecting portion 453 are brought into an engaged state, and as a result, the box base 263a and the box cover 263b are connected (the board box 263 is caulked), and the main controller 261 is Sealed again. In the present embodiment, the engaging portion 421 and the cover side connecting portion 453 correspond to the second sealing means.

  Note that, in the engaged state between the engaging portion 421 and the cover side connecting portion 453 (sealing state of the substrate box 263 by the second sealing means), the cover side connecting portion 453 is accommodated inside the box base body 401. The contact of the cover side connecting portion 453 and the engaging portion 421 to the engaging portion becomes very difficult or impossible. In particular, in the present embodiment, since the edge of the box base body 401 on the opening 402 side and the lid 451 of the box base 263a are in contact with each other, the box base body 401 and the box cover 263b are in contact with each other. Unauthorized acts such as the entry of a wire or the like into the inside of the board box 263 can be prevented.

  In the present embodiment, prior to the second sealing operation, the box base body 401 is broken along the removal slit 413 as shown in FIG. The breaking screw 418 screwed into the second mounting hole 412 from the left in the rear view of the machine 10 is removed, and the breaking screw 418 is screwed into the leftmost mounting hole 412 to attach the panel member 416 to the breaking screw. After sliding until it comes into contact with 418, the breaking screw 418 is screwed into the second mounting hole 412 from the right. As a result, in a state where the engaging portion 421 and the cover side connecting portion 453 are engaged, the positions of the receiving side connector 265 mounted on the main control device 261 and the connecting hole portion 417 of the panel member 416 coincide with each other. The side connector 265 and the plug-in side connector can be reliably connected.

  When opening the board box 263 in which the engaging portion 421 and the base side connecting portion 403 are engaged, the portion between the adjacent excision slits 422 is broken to engage with the box base main body 401. The part 421 (the part where the engaging part 421 is formed) is excised. Thereby, the substrate box 263 can be opened. When the box base body 401 is broken along the cutting slit 422 and the substrate box 263 is opened, the portion of the box base body 401 that engages with the cover side connecting portion 453 disappears. It cannot be sealed again. In this embodiment, a method other than removing the base-side connecting portion 403 from the box base 263a (for example, removing the cover-side connecting portion 453 from the box cover 263b or along the cutting slit 422). When the substrate box 263 is opened in such a manner that the substrate box 263 cannot be resealed.

  Next, the electrical configuration of the pachinko machine 10 will be described. FIG. 12 is a block diagram illustrating 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.

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.

  A CPU 551, ROM 552, and RAM 553 are connected to the input / output port 554 via a bus line 555 and a display control device 45 is connected. Further, the speaker SP, the effect button 125, various illumination units, and the lamps 102 to 104 are connected to the input / output port 554.

  The CPU 551 of the sub-control device 262 causes the display control device 45 to execute display control based on, for example, a command signal (for example, a variation pattern command) transmitted from the main control device 261 and causes the decorative symbol display device 42 to display the display control device. As described above, in the present embodiment, the special display device 43 controlled by the main control device 261 displays whether or not it is a big hit, and the decorative symbol display device 42 controlled by the sub control device 262. Then, display according to the display of the special display device 43 is performed.

  The payout control device 311 controls payout of prize balls and rental balls by the payout device 358. The CPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the CPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

  The RAM 513 of the payout control device 311, like the RAM 503 of the main control device 261, has a stack area for storing the contents of the internal registers of the CPU 511 and the return address of the control program executed by the CPU 511, various flags and counters, A work area (work area) in which values such as I / O are stored, and a backup area 513a are provided.

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.

  In the work area, a payout permission flag for which the payout control device 311 is set to allow the payout of prize balls, a command reception flag set when a command transmitted from the main control device 261 is received, and the main control device 261 And a command buffer for storing a command transmitted from.

  The payout permission flag is a flag for setting a prize ball payout permission, and is turned on when a specific command for permitting the payout of the prize ball is transmitted from the main control device 261 and received, and is initially set. 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 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. And. An input / output port 554 of the sub control device 262 is connected to the input port 527. 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 contents 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, the engagement portion 421 is released after releasing the engagement state between the base side connection portion 403 and the cover side connection portion 453 (the sealing state of the substrate box 263 by the first sealing means). In order to bring the cover side connecting portion 453 into an engaged state (sealed state of the substrate box 263 by the second sealing means), it is necessary to remove the base side connecting portion 403 from the box base 263a. For this reason, an opening trace is necessarily formed on the box base 263a provided with the base side connecting portion 403. Therefore, even if two substrate boxes 263 are prepared, it is impossible to obtain a box base 263a that has no trace of opening (unscratched). As a result, it is possible to prevent an act of illegally exchanging control means such as the main control device 261 and the ROM 502 so that it is not known that the replacement has been made, and such a situation can be prevented even if an illegal opening is performed. It can be discovered early and easily.

  Further, in the engaged state between the base side connecting portion 403 and the cover side connecting portion 453, the base side connecting portion 403 (locking member) is provided between the edge on the opening 402 side of the box base body 401 and the lid portion 451. 431), but when engaging the engaging portion 421 and the cover side connecting portion 453, the base side connecting portion 403 is removed, and the end of the box base body 401 on the opening 402 side is removed. The box cover 263b is pushed into the box base main body 401 until the edge comes into contact with the lid portion 451 (the lateral width of the substrate box 263 is reduced). That is, when the base side connecting portion 403 and the cover side connecting portion 453 are engaged (sealed state by the first sealing means), and when the engaging portion 421 and the cover side connecting portion 453 are engaged (second sealing). Since the appearance of the substrate box 263 is different from that in the case of the sealing state by the means, it is easy to grasp that the base side connecting portion 403 has been removed, and it can be easily found that the substrate box 263 has been opened. .

  Further, in the engaged state between the base side connecting portion 403 and the cover side connecting portion 453, the engaging portion 421 and the cover side connecting portion 453 are in a non-engaged state. When the engagement state with the portion 453 is released, it is not necessary to release the engagement between the engagement portion 421 and the cover side connection portion 453, and only the base side connection portion 403 is removed from the box base body 401. is there. In particular, in this embodiment, the base-side connecting portion 403 can be removed from the box base body 401 simply by pinching and pulling the knob portion 436. Further, the curable resin layer 432 that connects the locking member 431 and the box base body 401 has a thin portion near the boundary between the locking member 431 and the box base body 401, and pinches the knob 436. By pulling with, the thin-walled portion can be broken relatively easily. With these configurations, it is possible to improve workability when releasing the sealed state of the substrate box 263 by the engagement between the base side connecting portion 403 and the cover side connecting portion 453.

  Further, when the engaging portion 421 and the cover side connecting portion 453 are engaged, the space formed by removing the base side connecting portion 403 (locking member 431) is filled, so that the box base body 401 and the box cover 263b are only assembled. Therefore, it is possible to improve workability when the substrate box 263 is sealed again. In addition, since the engaging portion 421 and the base side connecting portion 403 are accommodated inside the substrate box 263 in an engaged state between the engaging portion 421 and the base side connecting portion 403, contact from the outside of the substrate box 263 is possible. Becomes very difficult or impossible. For this reason, the board | substrate box 263 can be reliably made into the sealing state by the engaging part 421 and the base side connection part 403, employ | adopting a comparatively simple structure.

  In addition, the opening 402 of the box base body 401 can be inserted only when the main controller 261 is relatively displaced along the longitudinal direction of the main controller 261 with respect to the box base 263a. It is configured to an allowable size. For this reason, the peripheral length of the opening 402 of the box base 263a can be shortened, and as a result, the length of the base side connecting portion 403 (locking member 431) provided so as to surround the opening 402 can be shortened. . Therefore, it is possible to improve workability at the time of sealing, reduce costs, and the like. Further, by providing the base-side connecting portion 403 so as to surround the opening 402, for example, a stronger seal can be performed as compared with the case where the base-side connecting portion 403 is provided only on one side of the opening 402. .

  Further, for example, when the base side connecting portion 403 and the cover side connecting portion 453 are integrally formed with the box base 263a and the box cover 263b, respectively, the base side connecting portion 403 and the cover side connecting portion 453 have high rigidity, When there is almost no flexibility, it is impossible to assemble the box base 263a and the box cover 263b, or the base side connecting portion 403 and the cover side connecting portion 453 may be damaged during the assembling. There is a fear. On the other hand, when the base side connecting portion 403 is made of a relatively soft material, the box base 263a and the box cover 263b can be easily assembled, but the base side connecting portion 403 and the cover side connecting portion 453 are connected. There is a possibility that the state (sealed state by the first sealing means) becomes fragile (can be easily opened without leaving a predetermined trace).

  In contrast, according to the present embodiment, initially, the locking member 431 configured separately from the box base main body 401 is fitted into the accommodating portion 464 of the cover side connecting portion 453 so that the box base main body 401 and the box cover 263b are fitted. After the alignment, the curable resin layer 432 is formed over the locking member 431 and the box base main body 401, whereby the base side connection portion 403 is configured, and the base side connection portion 403 and the cover side connection portion 453 are formed. Are engaged. Accordingly, the base-side connecting portion 403 and the cover-side connecting portion 453 are formed of an appropriate material that exhibits the above-described effects without worrying about the above-described problems in assembling the box base 263a and the box cover 263b. The engagement state between the side connecting portion 403 and the cover side connecting portion 453 can be ensured.

  Further, for example, the base side connecting portion 403 is integrally formed with the box base main body 401, and no step is formed between the outer surface of the lid portion 451 of the box cover 263b and the base portion 461 of the cover side connecting portion 453. When the connecting portion 921 and the cover side connecting portion 453 are engaged, if the box cover 263b is pushed too much into the box base 263a, the cover side connecting portion 453 is not the base side connecting portion 403 but the engaging portion. There is a risk of engaging with the mating portion 421. On the other hand, as shown in the present embodiment, the base-side connecting portion 403 and the cover-side connection are obtained by connecting the locking member 431 to the box base main body 401 with the box base main body 401 and the box cover 263b aligned. The part 453 can be reliably brought into an engaged state, and the above-described problem can be avoided. Of course, in a state where the cover side connecting portion 453 and the engaging portion 421 are engaged, there is no space for installing the locking member 431, and the base side connecting portion 403 is accurately connected to the box base body 401. I can't.

  In this embodiment, when the engagement state between the base side connecting portion 403 and the cover side connecting portion 453 is released, the base side connecting portion 403 is removed from the box base 263a, but the cover side connecting portion 453 is used. Is left in the box cover 263b and used when the substrate box 263 is sealed again. Therefore, it is possible to make the members related to the sealing of the board box 263 common. For example, it is used for the second sealing separately from the base side connecting portion 403 and the cover side connecting portion 453 used for the first sealing. Compared with the case where the engaging portion 421 and the engaged portion are provided, the configuration can be simplified.

  In addition, in this embodiment, the locking member 431 and the box base body 401 are connected by the curable resin layer 432. For this reason, the box base main body 401 and the locking member 431 can be connected relatively easily. In addition, since the recess 434 is formed in the locking member 431 and the curable resin layer 432 is formed in the recess 434, the locking member 431 and the curable resin layer 432 can be more reliably connected. Furthermore, the filling part 423 is formed in the box base main body 401, and the curable resin layer 432 is formed in the filling part 423, whereby the box base main body 401 and the curable resin layer 432 can be more reliably connected. . With these configurations, as a result, the locking member 431 and the box base body 401 can be more reliably connected.

  Further, by providing the flow stop 435 on the locking member 431, the concave portion 434 of the locking member 431 and the filling portion 423 of the box base body 401 are surely filled with the photocurable resin, and the curable resin layer 432 is filled. Can be reliably formed. In addition, since the locking member 431 has flexibility, the locking member 431 can be securely and relatively easily fitted into the accommodating portion 464. After the locking member 431 is fitted, the locking member 431 is inserted into the recess 434. By forming the curable resin layer 432, the rigidity of the locking member 431 can be increased, and the sealing state of the substrate box 263 (attachment state between the box base 263a and the box cover 263b) can be stabilized. it can.

  In addition, since a restricting piece 441 for restricting displacement of the locking member 431 (cover side connecting portion 453) in the direction of disengagement is provided, the base side connecting portion 403 is unintentionally detached from the box base main body 401. Can be prevented.

  Further, the box base body 401 and the box cover 263b are in an engaged state between the base side connecting portion 403 and the cover side connecting portion 453 and in an engaged state between the engaging portion 421 and the cover side connecting portion 453. Even if the relative position between the receiving-side connector 265 and the connector opening 411 of the main control device 261 changes with the change in the relative position of the main control device 261, the change is allowed by sliding the panel member 416. be able to. Therefore, the connector can be reliably connected. Furthermore, it is possible to prevent a situation in which a gap is generated between the receiving connector 265 and the peripheral edge portion of the connector opening 411 (connection hole portion 417). In particular, in this embodiment, since the displacement of the panel member 416 is regulated by the breaking screw 418 screwed into the mounting hole 412 in each sealed state, for example, the insertion side connector is removed from the receiving side connector 265, and the panel member By sliding 416, a situation in which a gap is formed between the receiving connector 265 and the peripheral edge of the connection hole 417 can be prevented. Therefore, it is possible to prevent a situation in which contact with the main control device 261 is achieved through the connector opening 411 (connection hole 417).

  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, when the substrate box 263 is sealed for the second time, the edge on the opening 402 side of the box base body 401 and the lid 451 of the box cover 263b are in contact with each other. It is not limited to such a configuration. However, the box base body 401 and the box cover 263b are disposed closer to the opening 402 side than the engaging portion in order to prevent external contact with the engaging portion between the engaging portion 421 and the cover side connecting portion 453. It is desirable to make it contact or install the engaging part away from the opening 402.

  Further, as shown in FIG. 13, a locking recess 701 is provided at the edge of the box base body 401 on the opening 402 side, and the engaging portion 421 and the cover side with respect to the peripheral portion of the lid portion 451 of the box cover 263b. It is good also as providing the protrusion 702 inserted in the said latching recessed part 701 when engaging the connection part 453. FIG. In this case, the positional deviation between the box base main body 401 and the cover side connecting portion 453 in the direction orthogonal to the assembling direction of the box base 263a and the box cover 263b at the abutting portion between the box base main body 401 and the cover side connecting portion 453. Can be prevented. Therefore, the sealed state can be stabilized.

  In addition, in the above embodiment, the cutting slit 422 is formed in the box base 263a (box base main body 401), but the cutting slit 422 may be formed in the box cover 263b. In this case, the cutting slit 422 can be provided at a position as far as possible from the central portion of the substrate box 263 accommodated in the substrate box 263, and a wire or the like enters from the cutting slit 422 to be mounted on the main controller 261 ( It is possible to suppress fraudulent acts such as making contact with the main electrical member). Further, it is possible to prevent a situation in which the engagement state with the engaging portion 421 is released by contacting the cover side connecting portion 453 via the cutting slit 422.

  (B) The structure of the sealing means for sealing the substrate box 263 is not particularly limited, and the box box 263 can be sealed at least twice, and the box base is released when the first sealed state is released. It is sufficient that the second sealing is not performed unless an opening trace is left in at least one of the 263a and the box cover 263b.

  Hereinafter, the example of an aspect shown in FIG. 14 is demonstrated. FIG. 14A is a partial cross-sectional view showing a connection portion of the substrate box 263 in the first sealed state, and FIG. 14B is a partial cross-section showing a connection portion of the substrate box 263 in the second sealed state. FIG.

  The box base 263a shown in FIG. 14 has a connecting hole 801 penetrating in the inner and outer peripheral directions of the opening 402 at the peripheral edge of the opening 402, and the back side in the insertion direction of the main controller 261 from the connecting hole 801 (FIG. 14). The left side of the box base 263a has an engagement recess 802 formed on the inner surface of the box base 263a, and a cutting slit 803 formed between the connection hole 801 and the engagement recess 802.

  Further, the box cover 263b is a connecting recess 811 formed on the outer surface of the box cover 263b at the peripheral edge of the cover side opening 452 that is positioned on the inner peripheral side of the box base 263a in the assembled state of the substrate box 263. And on the front side of the main controller 261 in the insertion direction of the main controller 261 (on the right side in FIG. 14), between the engagement protrusion 812 protruding outward of the box cover 263b, and between the connection recess 811 and the engagement protrusion 812. And an excision slit 813 formed on the substrate.

  The connection hole 801, the engagement recess 802, the connection recess 811, and the engagement protrusion 812 are formed in a portion excluding the corner portion along the circumferential direction of the opening 402 and the cover side opening 452. A plurality of cutting slits 803 and 813 formed in the box base 263a and the box cover 263b are formed at predetermined intervals along the circumferential direction of the opening 402 and the cover-side opening 452.

  In the first sealing, the connecting hole 801 and the connecting recess 811 are aligned, the connecting hole 801 and the connecting recess 811 are filled with a photocurable resin, cured, and cured through the connecting hole 801 and the connecting recess 811. By forming the resin layer 821, the box base 263a and the box cover 263b are connected.

  When releasing the seal, the box base 263a and the box cover 263b are broken along the cutting slits 803 and 813 formed in the box base 263a and the box cover 263b, respectively, and the connection holes of the box base 263a and the box cover 263b are cut. The portion where the 801 and the connecting recess 811 are formed is removed from the substrate box 263. Thereby, the substrate box 263 is opened. In the second sealing, the box base 263a and the box cover 263b are connected by bringing the engagement recess 802 and the engagement protrusion 812 into an engaged state.

  Even in the case of adopting the above-described configuration, the same operational effects as the above-described embodiment are basically obtained. However, when this configuration is adopted, the lateral width of the substrate box 263 changes relatively greatly between the first sealed state and the second sealed state. For this reason, while it becomes easy to grasp that the first seal is released, it is necessary to preliminarily mold the substrate box 263 in anticipation of the substrate box 263 becoming smaller at the second seal. On the other hand, in the above embodiment, since the change in the lateral width of the substrate box 263 is relatively small as compared with the configuration (b), such a situation can be prevented.

  (C) In the above embodiment, by removing the base side connecting portion 403 from the box base 263a, the engagement state between the base side connecting portion 403 and the cover side connecting portion 453 is released, and the substrate box 263 is again formed. The cover side connecting portion 453 is removed from the box cover 263b so that the engagement state between the base side connecting portion 403 and the cover side connecting portion 453 is released. The substrate box 263 may be sealed again.

  Further, as shown in FIG. 15B, a first connector opening 931 and a second connector opening 932 into which the receiving connector 265 can be inserted are formed in the upper and lower portions of the rear wall portion 911 of the box cover 263b. Has been. The first connector opening 931 and the second connector opening 932 have the same opening shape, and are provided at symmetrical positions around the center of the box cover 263b (rear wall 911). The box cover 263b is provided with a closing panel 935 that closes the second connector opening 932. Attachment holes 936 that pass through in the front-rear direction are formed on both sides of the closing panel 935. In contrast, on the front surface of the rear wall portion 911, bosses 937 as panel attachment portions having screw holes are provided on both sides of the second connector opening 932, and the bosses 937 and the attachment holes 936 are positioned. Aligned and fixed with screws. The boss 937 is also formed on both sides of the first connector opening 931.

  In the first sealing, after engaging the locking member 431 in the groove portion 905, the box base 263a and the box cover 263b are overlapped in the front-rear direction, and the distal end portion of the extending wall portion 912 and the groove portion 905 outward. The protruding locking member 431 is brought into a contact state. Thereafter, the concave portion 434 of the locking member 431 is filled with a photocurable resin and cured, and the curable resin layer 432 is formed between the locking member 431 and the extending wall portion 912. As a result, the locking member 431 connected to the extended wall portion 912 and the groove portion 905 are engaged, and the box base 263a and the box cover 263b are coupled (the substrate box 263 is sealed). .

  In this state, the position of each locking portion 913 and the position of the mounting piece 903 (locking hole 904) do not match in the assembly direction of the box base 263a and the box cover 263b. The portion 913 and the mounting piece 903 are not locked.

  When releasing the seal, the curable resin layer 432 is broken and the connecting portion 921 is removed from the box cover 263b. Thereby, the substrate box 263 is opened.

  When sealing for the second time, first, the closing panel 935 that has closed the second connector opening 932 is removed, and the closing panel 935 is attached corresponding to the first connector opening 931. Thereafter, the box cover 263b is rotated 180 degrees from the posture in the first sealed state (upside down) with the front-rear direction as the rotation axis direction. Thereby, in the assembly direction of the box base 263a and the box cover 263b, the position of each locking portion 913 and the position of the mounting piece 903 are matched, and the box base 263a and the box cover 263b are assembled and pressed. Thus, the locking portion 913 is locked to the mounting piece 903 (the locking piece portion 914 is inserted into the locking hole 904 and the locking claw portion 915 is locked to the front surface of the mounting piece 903). As a result, the box base 263a and the box cover 263b are connected (the substrate box 263 is sealed).

  When the locking portion 913 and the mounting piece 903 are locked, the box cover 263b is broken along the cutting slit 917 so that the locking portion 913 is removed from the box cover 263b and the substrate box 263 is opened. can do.

  Even in the case of adopting the above-described configuration, the same operational effects as the above-described embodiment are basically obtained. In addition, when the configuration is adopted, the box base 263a is turned upside down between the first sealed state and the second sealed state, so that the appearance of the substrate box 263 changes greatly, It becomes easier to grasp that the second seal has been released. Furthermore, when the second sealing is performed, only the box base 263a is reversed with respect to the box base 263a and assembled, so that the relative positions of the box base 263a and the box cover 263b change. A situation in which the size of the substrate box 263 changes can be avoided. For this reason, for example, it is not necessary to make the substrate box 263 large in anticipation that the substrate box 263 becomes small when performing the second sealing. Therefore, the enlargement of the substrate box 263 can be prevented, and due to the enlargement of the substrate box 263, an extra space for installing the substrate box 263 is required on the back side of the pachinko machine 10. The situation can be prevented.

  Further, since the first connector opening 931 and the second connector opening 932 having the same shape are provided on the upper and lower sides of the rear wall portion 911 of the box cover 263b at symmetrical positions, the box cover 263b is moved up and down with respect to the box base 263a. Even if it is reversed and attached, the connector can be securely connected. Further, since the unused connector openings 931 and 932 are closed by the closing panel 935, an unauthorized operation is performed on the main controller 261 via the unused connector openings 931 and 932. Can be prevented.

  Further, since the closing panel 935 is attached to the front surface of the box cover 263b, it is impossible to remove the closing panel 935 unless the substrate box 263 is opened. Accordingly, it is not necessary to use a break screw, a one-way screw, etc., the structure can be simplified, workability can be improved when the closing panel 935 is replaced, and the closing panel 935 can be easily removed. it can. Further, in the second sealing, it is only necessary to remove the closing panel 935 attached corresponding to the second connector opening 932 and attach the closing panel 935 corresponding to the first connector opening 931. When performing the second sealing, it is not necessary to prepare a separate blocking panel, and workability can be improved.

  (D) In the above embodiment, the locking member 431 and the box base body 401 are connected using a photocurable resin. However, the present invention is not particularly limited to such a configuration. For example, other resins The curable resin layer 432 may be formed by the above. That is, any resin may be used as long as it is initially liquid or pasty and has a property of curing after filling. For example, a thermosetting resin or a thermoplastic resin may be adopted as long as it is an ultraviolet curable resin that is cured by irradiating with ultraviolet rays, or a resin that does not adversely affect the substrate box 263.

  Although not mentioned in the above embodiment, examples of the “photocurable resin” include an epoxy-based resin and an oxetane-based resin. In addition, the “ultraviolet curable resin” is not limited to those whose curing mechanism is solely based on ultraviolet rays, but is cured by humidity in the air, anaerobic curing by metal ions, curing by slight heating, and curing by a curing catalyst. It may be by composite curing such as. In addition, examples of the thermosetting resin include phenol resin, melanin resin, urea resin, and the like. Examples of the thermoplastic resin include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamide, acrylic, and ABS.

  Further, a tool engaging portion (cross hole or the like) is formed after screwing in connection between the locking member 431 and the box base main body 401 and the connection between the box base main body 401 and the box cover 263b at the second sealing. It is also possible to use a break screw that can remove the damaged part or a one-way screw that cannot be turned in the removing direction.

  (E) In the above embodiment, the base side connecting portion 403 (the locking member 431) and the box base main body 401 are initially configured as separate bodies, and the box base main body 401 and the box cover 263b are aligned with each other (engagement). The base side connecting portion 403 is connected and molded to the box base body 401 in a state where the joining portion 421 and the cover side connecting portion 453 are in contact with each other in a non-engaged state. The configuration is not limited. For example, when the box base 263b is formed, the box base body 401 and the base-side connecting portion 403 may be integrally formed at the same time. After the box base body 401 is formed, the box base body 401 and the box cover 263b are positioned. The base side connecting portion 403 may be connected and molded to the box base main body 401 before the alignment. For example, when the former configuration is adopted, when the box base 263b is formed, the base side connecting portion 403 is formed so as to open to the outer peripheral side of the opening 402, and the box base body 401 and the box cover 263b are positioned. After matching, it is conceivable to process the base side connecting portion 403 so as to deform toward the inner peripheral side of the opening 402. However, the possibility that the trace of opening is processed so as to be difficult to understand is suppressed, and various problems (for example, breakage of the connecting portions 403 and 453, assembling workability, etc.) are caused when the box base 263a and the box cover 263b are assembled. From the standpoint of securely assembling the substrate box 263 without incurring a decrease in the box base body 401 and the box cover 263b as in the above embodiment, the box base body 401 and the base are aligned. It is desirable to connect the side connecting portion 403.

  (F) In the above embodiment, the substrate box 263 is configured to be able to be sealed twice in total, but may be configured to be sealed three times or more. For example, the box base 263a is provided with a locking claw that protrudes to the inside of the box base 263a on the left side of the cutting slit 422 in FIGS. 9 (a) and 9 (b), and the engaged portion 421 is made to be the box base. After removing from 263a, the board | substrate box 263 is good also as a structure sealed by engaging the engaging part 421 with the said latching claw.

  (G) Although not particularly mentioned in the above embodiment, the color of the base-side connecting portion 403 (for example, the locking member 431 is colored and a colored transparent photocurable resin is used), and the box base main body 401 and the box cover 263b may be different in color (colorless and transparent). In this case, it becomes easy to grasp that the base side connecting portion 403 has been removed. Further, by coloring the curable resin layer 432, for example, after removing the base side connecting portion 403 and tampering with opening the substrate box 263, the removed base side connecting portion 403 is removed using a photocurable resin. When an illegal act of connecting to the box base body 401 is performed again, the original material left on the locking member 431 and the box base body 401 even after the base side connecting portion 403 of the curable resin layer 432 is removed. It is difficult to match the colors of the portion that is the curable resin layer 432 and the portion that is configured by the photocurable resin that is used in the case of fraud, and it is easy to find the fraud.

  (H) In the above embodiment, a slit (extending along the direction intersecting with the longitudinal direction of the locking member 431) is formed in the locking member 431 (a predetermined portion in the longitudinal direction thereof), and the base side connecting portion 403 is formed. When the is removed from the box base body 401, the locking member 431 may be broken at the slit. In this case, if the base side connecting portion 403 is broken and the substrate box 263 is opened, the locking member 431 is broken. For example, the base side connecting portion 403 is removed and the substrate box 263 is tampered with, and then light curing is performed. An illegal act such as re-connecting the removed base-side connecting portion 403 to the box base main body 401 can be suppressed using the functional resin.

  (I) In the above embodiment, an embedded member embedded in the curable resin layer 432 may be installed between the recessed portion 434 of the locking member 431 and the filling portion 423 of the box base body 401. In the case of adopting this configuration, after removing the base side connecting portion 403 and opening the substrate box 263 again, an illegal act of connecting and forming the base side connecting portion 403 to the box base body 401 again using a photo-curing resin. Even if it is performed, unauthorized opening can be grasped more reliably by checking the embedded member. It is desirable that the embedded member has physical properties such that the curable resin layer 432 is broken at the same time as it is broken.

  (J) 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.

  (K) You may implement as a different type of pachinko machine from the above-mentioned embodiment. In addition to pachinko machines, various ball games, similar sparrow balls and other gaming machines, slot machines as revolving game machines, and other types of gaming machines that combine slot machines and pachinko machines, etc. May be.

[Appendix]
The technical idea that can be grasped from the above embodiment will be described below.

Means 1. A box base for accommodating a control board having various control means;
A box cover covering the opening of the box base;
A first sealing means for connecting the box base and the box cover, and sealing the control substrate accommodated in the substrate box;
After the sealed state by the first sealing means is released, the box base and the box cover are connected again, and the second sealing means for sealing the control board accommodated in the board box is provided. Equipped with a board box,
The first sealing means includes a base side connecting portion provided on the box base, and a cover side connecting portion provided on the box cover and connected to the base side connecting portion, and the base side connecting portion and A predetermined one of the cover side connecting portions is removed from the corresponding box base or the box cover, and the other is left on the corresponding box base or the box cover, or the base side connecting portion and By removing both of the cover side connecting portions from the box base or the box cover, the sealing state by the first sealing means can be released, and the substrate box can be sealed by the second sealing means. A gaming machine characterized by

  According to the means 1, in order to release the sealed state of the substrate box by the first sealing means (the connected state of the base side connecting portion and the cover side connecting portion) and to seal the substrate box again by the second sealing means, It is necessary to remove (destroy) at least one of the base side connecting portion and the cover side connecting portion from the box base or the box cover. For this reason, an opening trace is necessarily formed on the box base or the box cover provided with at least one of the base side connecting portion and the cover side connecting portion. Therefore, even if two substrate boxes are prepared, it is impossible to obtain a box base and a box cover that have no trace of opening (no damage). As a result, it is possible to prevent the act of illegally exchanging the control means such as the control board and ROM so that it is not known that it has been replaced. And it can be easily discovered.

  Also, due to the presence of the second sealing means, in the game hall or the like, the sealed state of the board box by the first sealing means is released, the control board is taken out from the board box and inspected or replaced, and then the second sealing means The substrate box can be sealed again.

  In addition, “when the predetermined one of the base side connecting portion and the cover side connecting portion is left in the corresponding box base or the box cover, and the other is removed from the corresponding box base or the box cover, It may be impossible to seal the substrate box by the second sealing means ”. Further, each of the box base and the box cover may be constituted by one member or a plurality of members. Further, the base side connecting portion and the cover side connecting portion may be provided so as not to be removable from the box base and the box cover (unless the box base and the box cover are partially broken). It may be integrally formed with the cover, or may be configured as a member separate from the box base and the box cover. Further, as control means, a ROM storing a control program and fixed value data, a RAM which is a memory for temporarily storing various data when executing the control program stored in the ROM, and various circuits are incorporated. A CPU as a one-chip microcomputer is available.

Mean 2. The second sealing means includes an engaging portion provided on one side of the box base and the box cover, and an engaged portion provided on the other side and engageable with the engaging portion. By removing at least one of the engaging part and the engaged part from the corresponding box base or the box cover, the sealing state by the second sealing means can be released,
When the substrate box is in a state sealed by the first sealing means, the engaging portion and the engaged portion are in a relative position where they cannot be engaged,
When the sealing state by the first sealing means is released by removing one or both of the base side connecting part and the cover side connecting part from the box base or the box cover, By assembling the box base and the box cover at a relative position different from that in the sealed state by the first sealing means, the engaging portion and the engaged portion are brought into an engaged state. The gaming machine according to means 1 characterized by the above.

  According to the means 2, the sealing by the second sealing means is performed by assembling the box base and the box cover at a relative position different from that in the sealing state by the first sealing means, and in the sealing state by the first sealing means. This is performed by engaging the engaged portion and the engaged portion in the combined state. That is, the relative position of the box base and the box cover is different between the sealed state by the first sealing means and the sealed state by the second sealing means. Therefore, since the appearance of the substrate box changes between when it is sealed by the first sealing means and when it is sealed by the second sealing means, it is relatively easy for the seal by the first sealing means to be released. I can grasp it.

  Further, since the engaging portion and the engaged portion are in the disengaged state when the first sealing means is in the sealed state, when the sealing state by the first sealing means is released, the engaging portion and the engaged portion are engaged. There is no need to release the engaged state with the joint portion, and only at least one of the base side connecting portion and the cover side connecting portion is removed from the box base or the box cover. Further, when the sealing by the second sealing means is performed, the box base and the box cover are simply assembled at a relative position different from the sealed state by the first sealing means. Accordingly, it is possible to improve workability when releasing the seal by the first sealing means and resealing.

Means 3. The first sealing means is provided exposed to the outer surface side of the substrate box along the opening of the box base in the sealed state of the substrate box by the first sealing means,
The second sealing means is characterized in that at least an engagement portion between the engaging portion and the engaged portion is accommodated inside the substrate box in a sealed state of the substrate box by the second sealing means. The gaming machine according to means 1 or 2.

  According to the means 3, since the first sealing means is exposed and provided outside the substrate box, it is easy to find a trace when the sealing by the first sealing means is released, and the substrate box is opened. Can be easily discovered. Furthermore, the operation of releasing the sealed state by the first sealing means (removal operation of the base side connecting portion and the cover side connecting portion) can be performed relatively easily. In addition, since the engaging portion and the engaged portion are very difficult or impossible to contact from the outside of the substrate box, the substrate box is securely secured by the second sealing means while adopting a relatively simple configuration. Can be sealed.

Means 4. The opening that is formed in the box base and allows the control board to pass through the box base is formed when the control board is displaced relative to the box base along the longitudinal direction of the control board. The control board is allowed to be inserted, and when the control board is relatively displaced with respect to the box base along a direction other than the longitudinal direction of the control board, the control board cannot be inserted. Has a size,
4. The gaming machine according to claim 1, wherein the first sealing means is provided so as to surround the opening of the box base.

  According to the means 4, the peripheral length of the opening of the box base can be shortened, and as a result, the length of the first sealing means provided so as to surround the opening can be shortened. Therefore, it is possible to improve the workability at the time of sealing by the first sealing means and reduce the cost. Further, by providing the first sealing means so as to surround the opening, for example, it is possible to perform a more robust sealing as compared with the case where the first sealing means is provided only on one side of the opening.

  The box cover includes a lid portion that closes the opening of the box base and a holding portion that holds a control board, and the box cover is displaced by removing the box cover from the box base. Accordingly, the control board held by the holding unit may be taken out from the box base. " In this case, it is possible to improve workability when removing the box cover and taking out the control board while the box base is attached to the gaming machine main body.

  Means 5. The predetermined one of the base-side connecting portion and the cover-side connecting portion is provided with a breaking portion where the one is separated from the corresponding box base or the box cover by breaking. 5. A gaming machine according to any one of means 1 to 4.

  According to the means 5, it is possible to improve workability when releasing the sealed state by the first sealing means. The broken portion can be cut using a tool or broken by hand when releasing the sealed state of the substrate box by the first sealing means (when opening the substrate box). This is a part formed in advance in the substrate box.

  In addition, a knob portion is provided on the predetermined one of the base side connecting portion and the cover side connecting portion, and the operator pulls the knob portion to break the fracture portion, It may be separated from the corresponding box base or the box cover. The substrate box is detachably attached to the substrate box, and restricts one of the predetermined displacements of the base side connecting portion and the cover side connecting portion in a sealed state by the first sealing means. It is good also as providing the regulation means to do. In this case, it is possible to prevent a situation in which the predetermined one is unintentionally detached from the corresponding box base or box cover.

Means 6. The predetermined one of the base-side connecting portion and the cover-side connecting portion initially includes a locking member configured separately from the box base and the box cover, and the box base and the box cover. In a state of aligning, the non-removable connection to the corresponding box base or the box cover,
When the predetermined one of the base side connecting part and the cover side connecting part is provided integrally with the corresponding box base or the box cover, the base side connecting part and the cover The gaming machine according to any one of means 1 to 5, wherein the side connecting portion is connected.

  For example, when the base side connecting part and the cover side connecting part are integrally formed with the box base and the box cover, respectively, and the base side connecting part and the cover side connecting part have high rigidity and little flexibility. If a manufacturing error occurs, it may be impossible to assemble the box base and the box cover, or the base side connecting part and the cover side connecting part may be damaged during the assembling. On the other hand, when the base side connecting part and the cover side connecting part are made of a relatively soft material, the box base and the box cover can be easily assembled, but the base side connecting part and the cover side connecting part are connected. There is a possibility that the (sealed state by the first sealing means) becomes fragile (can be easily opened without leaving a predetermined trace).

  On the other hand, according to the means 6, the locking member initially configured as a separate body from the box base and the box cover is attached to the corresponding box base or box cover in a state where the box base and the box cover are aligned. By connecting, the predetermined one of the base side connecting portion and the cover side connecting portion is formed. Therefore, the base side connecting portion and the cover side connecting portion are made of an appropriate material without worrying about the above-mentioned problems in assembling the box base and the box cover, and the base side connecting portion and the cover side connecting portion are connected. The state can be ensured.

  Further, as in this means, the first base means is sealed by connecting the locking member to the box base or the box cover in a state where the box base and the box cover are aligned. It is possible to avoid a situation in which the sealing by the second sealing means is performed when the substrate box is sealed by the first sealing means.

  Mean 7 The gaming machine according to claim 6, wherein the locking member is connected to the corresponding box base or the box cover by a curable resin layer formed by curing a curable resin. .

  According to the means 7, the locking member can be connected to the box base or the box cover relatively easily.

  In addition, about a connection part with a box base or a box cover among curable resin layers, when a stress acts on the direction which makes a locking member detach | leave from a box base or a box cover, it is a grade which is destroyed (ruptured). It may be brittle. In this case, it is possible to improve workability when releasing the sealed state by the first sealing means. Furthermore, the thickness of the curable resin layer can be changed relatively easily by changing the filling amount of the curable resin. Therefore, for example, when the curable resin layer is partially thin (in the vicinity of the connecting portion between the locking member and the box base or the box cover) and the substrate box is forcibly opened, the thin portion of the curable resin layer is It can also be set as the structure which is fractured | ruptured and a latching member detach | leaves from a box base or a box cover.

The curable resin refers to a resin that is initially liquid or pasty and has a property of curing after filling. As curable resin,
(1) Photo-curable resin: a resin that is cured by irradiating light such as laser light,
(2) UV curable resin: a resin that is cured by irradiating with UV rays;
(3) Other: Thermosetting resins and thermoplastic resins can be used as long as they do not adversely affect the substrate box. Examples of the “photocurable resin” include an epoxy type and an oxetane type. The “ultraviolet curable resin” is not limited to the one whose curing mechanism is solely based on ultraviolet rays, but includes curing by humidity in the air, anaerobic curing by metal ions, curing by slight heating, curing by a curing catalyst, etc. It may be by composite curing. Examples of the thermosetting resin include phenol resin, melanin resin, urea resin, and the like. Examples of the thermoplastic resin include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, polyamide, acrylic, and ABS.

Means 8. The locking member has a bottomed recess,
A stepped portion is formed at the connection portion of the box base or the box cover to which the locking member is connected by the curable resin layer,
The locking member and the corresponding box base or the box cover are connected by filling the concave portion and the stepped portion with a curable resin to form the curable resin layer. A gaming machine according to claim 7.

  According to the means 8, since the curable resin layer is formed in the recess, the locking member and the curable resin layer can be reliably fixed. Moreover, by forming the curable resin layer in the stepped portion, the box base or the box cover and the curable resin layer can be securely fixed. As a result, the box base or the box cover and the locking member can be more reliably connected.

Means 9. One of the base side connecting portion and the cover side connecting portion is removed from the box base or the box cover when the sealed state by the first sealing means is released, and the other is the box. It is the structure left in the base or the box cover,

  According to the means 9, the configuration can be simplified by sharing a part of the first sealing means and the second sealing means.

Means 10. In the box base or the box cover, a connector opening for connecting the insertion side connector to the receiving side connector mounted on the control board is formed,
Corresponding to the connector opening, a panel member having a connection hole portion through which the insertion-side connector can be inserted is slidably provided,
The gaming machine according to any one of means 1 to 9, further comprising a displacement restricting means for restricting displacement of the panel member when the first sealing means and the second sealing means are in a sealed state. .

  According to the means 10, when the relative position between the receiving connector mounted on the control board and the connector opening is shifted between the sealed state by the first sealing means and the sealed state by the second sealing means. Even if it exists, this change can be accept | permitted by sliding a panel member. Therefore, the connector can be reliably connected. In addition, it is possible to prevent a situation in which a gap is generated between the receiving connector and the peripheral portion of the connector opening (connection hole). In particular, this means is provided with a displacement restricting means for restricting the displacement of the panel member in each sealed state. For example, by removing the insertion side connector from the receiving side connector and sliding the panel member, It is possible to prevent a situation in which a gap is formed between the side connector and the peripheral edge of the connection hole. Therefore, it is possible to prevent a situation in which contact with the control board is achieved through the connector opening (connection hole).

Means 11. Of the box base, the peripheral portion of the opening and the butting portion of the box cover that are abutted with the peripheral portion of the opening of the box base are centered on the center of the box base and the box cover, respectively. Configured in a symmetrical shape,
In the sealed state by the first sealing means, the positions of the engaging portion and the engaged portion do not match in the assembly direction of the box base and the box cover, and the engaging portion and the engaged portion are not aligned. The joint is in a disengaged state,
When sealing by the second sealing means, the box cover is assembled to the box base in a posture reversed from the posture when the substrate box is in the sealed state by the first sealing means, The engaging portion and the engaged portion are aligned in the assembling direction of the box base and the box cover, and the engaging portion and the engaged portion are engaged.

  According to the means 11, the appearance of the substrate box is remarkably changed between when it is in the sealed state by the first sealing means and when it is in the sealed state by the second sealing means. For this reason, it can discover more easily that the sealing by the 1st sealing means was cancelled | released. Further, in this means, when sealing by the second sealing means, the box base is simply reversed and assembled with respect to the box base, so that the relative position of the box base and the box cover changes. Thus, it is possible to avoid a situation in which the size of the substrate box changes. For this reason, for example, it is not necessary to form a large substrate box in anticipation of a small substrate box when sealing by the second sealing means. Therefore, an increase in the size of the board box can be prevented, and a situation in which an extra space for installing the board box is required on the back side of the gaming machine due to the increase in the size of the board box is prevented. be able to.

  It should be noted that “a plurality of the engaging portions and the engaged portions may be provided and installed at asymmetric positions with respect to the box base and the box cover”. By providing a plurality of engaging portions and engaged portions in this way, the sealed state by the second sealing means can be stabilized.
