  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 includes a general winning opening 31, a variable winning device 32, a starting winning device 33 (for example, an operation chucker), a third starting port 34 (for example, a through gate), and a variable display unit 35. The general winning port 31, the variable winning device 32, the starting winning device 33, the third starting port 34, and the variable display device unit 35 are respectively disposed in the through holes formed by router processing in the game board 30. The game board 30 is attached from the front side with a wood screw or the like. A game ball enters the general winning port 31, the variable winning device 32, and the starting winning device 33, and the received ball is detected by a detection switch (winning port switch, count switch, operation port switch) (not shown) described later. Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15).

  In addition, as shown in FIG. 2, the start winning device 33 includes a first start port 33a (for example, an operation chucker) and a second start port 33b (for example, an operation chucker) arranged in order from the top to the bottom. It consists of a single winning device. The upper first starting port 33a is provided with an operating port switch (passage detection switch) for the first starting port 33a (not shown). It is detected by an operation port switch (not shown) for one start port 33a. The lower second start port 33b is provided with an operation port switch (passage detection switch) for the second start port 33b (not shown). It is detected by an operation port switch (not shown) for the second start port 33b. That is, in either case of entering a game ball into the first start port 33a on the upper side or entering a game ball into the second start port 33b on the lower side, it is a start prize. There is no change, and the incoming balls can be detected individually.

  In addition, as shown in FIG. 2, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like pass through the out port 36 in a ball discharge path (not shown). You will be guided to the direction. A large number of nails (not shown) are planted in the game area 30a of the game board 30 in order to appropriately distribute and adjust the falling direction of the game balls.

  The variable display device unit 35 includes a first symbol display device 40 that variably displays a first symbol (for example, a special symbol) as identification information with a winning at the first starting port 33a and the second starting port 33b as a trigger. Using the passage of the third start port 34 as a trigger, the second symbol display device 41 that variably displays the second symbol (for example, the normal symbol), and the first start port 33a and the second start port 33b are awarded. As a trigger, a third symbol display device 42 that variably displays a third symbol (for example, a decorative symbol) is provided.

  The first symbol display device 40 includes, for example, a plurality of (two in the present embodiment) two-color light emitting type LEDs (light emitting diodes) 40a that emit variable light emission or the like based on the ball entering the first start port 33a. 40b, a hold display portion 40c displayed on the screen of the third symbol display device 42, which indicates the number of hold of the variable display by the LEDs 40a, 40b, and a variable light emission based on the ball entering the second start port 33b A plurality of (two in this embodiment) two-color light emitting type LEDs (light emitting diodes) 40d, 40e and the number of variable display suspensions on the LEDs 40d, 40e are displayed on the third symbol display device 42 as a screen display. The hold display unit 40f is provided.

  For example, the LEDs 40a and 40b that perform variable light emission based on entering the first start port 33a can emit red and blue light. The first symbol display device 40 generates a variable display state of the first symbol (in this embodiment, the emission color mode of each LED 40a, 40b) by alternately changing the emission color of each LED 40a, 40b, for example, When both LEDs 40a and 40b stop in a red light emitting state, a probable big hit (specific hit) is indicated, and when both LEDs 40a and 40b stop in a blue light emitting state, a normal big hit (non-specific hit) is indicated, and both LEDs 40a and 40b are mutually connected. When it stops in the light emission state of a different color, it will show off.

  Similarly to the above, the LEDs 40d and 40e that emit light in a variable manner based on the ball entering the second start port 33b can emit light in red and blue, for example. The first symbol display device 40 generates a variable display state of the first symbol (in this embodiment, the emission color mode of each LED 40d, 40e) by alternately changing the emission color of each LED 40d, 40e, for example, When both LEDs 40d and 40e stop in a red light emitting state, a promiscuous big hit (specific hit) is indicated, and when both LEDs 40d and 40e stop in a blue light emitting state, a normal big hit (non-specific hit) is indicated, and both LEDs 40d and 40e are mutually connected. When it stops in the light emission state of a different color, it will show off.

  In addition, as this 1st symbol display apparatus 40, you may employ | adopt the single LED of the type which can light-emit at least 3 colors or more, and by performing light emission of each color alternately, the 1st symbol is displayed. When the LED stops in the light emission state of the first color, it shows a probable big hit (specific hit), and when the LED stops in the light emission state of the second color, it usually shows a big hit (non-specific hit) When the LED stops in the light emission state of the third color, it may be indicated that the LED has come off. The first symbol display device 40 described above corresponds to the identification information fluctuation display means in the present invention.

  The second symbol display device 41 includes, for example, a display unit 41a on which “○” is drawn for the second symbol, a display unit 41b on which “x” is drawn for the second symbol, and the third symbol display. Each time the game ball passes through the third starting port 34, the display symbols (ordinary symbols) displayed by the display units 41a and 41b fluctuate. When the engine stops at a predetermined symbol, the second start port 33b on the lower side is configured to be activated (opened) for a predetermined time. The number of times that the game ball has passed through the third start port 34 is held up to a maximum of 4 times, and the number of times of holding is displayed on the hold display section 41c. The display units 41a and 41b have LEDs (light emitting diodes) inside thereof, and are configured to be variably displayed by switching the light emission of the LEDs (or lighting of the lamps). The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The 3rd symbol display apparatus 42 is comprised, for example with the liquid crystal display device, and the display content is controlled by the display control apparatus 45 mentioned later. On the third symbol display device 42, for example, as shown in FIG. 5 described later, three decorative symbol rows L, M, and R on the left, middle, and right are displayed. Each of the decorative symbol rows L, M, R is composed of a plurality of decorative symbols, and these decorative symbols are variably displayed on the third symbol display device 42 so as to be scrolled for each of the decorative symbol rows L, M, R. It has become so. In the present embodiment, the third symbol display device 42 (liquid crystal display device) includes, for example, a large liquid crystal display of 11 inch size. The variable display device unit 35 is provided with a center frame 47 on the front side of the third symbol display device 42 so as to substantially surround the display screen of the third symbol display device 42 when viewed from the front. The above-described third symbol display device 42 corresponds to decoration identification information (design) variation display means in the present invention, and the above-described display control device 45 corresponds to display control means in the present invention.

  As shown in FIG. 2, the variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is easy to win in a big hit and a normal closed state. It is operated repeatedly. In this way, the state in which the variable winning device 32 is repeatedly operated in the open state and the normal closed state at the time of a big win is called a specific gaming state (for example, a big winning state), and the variable winning device 32 has a large number of games. Since the ball enters (wins) and a lot of game balls are paid out for the winning, the game state is advantageous to the player. That is, in the pachinko machine 10 of the present embodiment, the number of game balls thrown in (the number of game balls launched into the game area 30a by the game ball launching device 38) is the number of game ball award balls paid out (general winning port 31). , The number of prize balls paid out based on the number of game balls entered into the variable prize device 32, the start prize device 33, the third start port 34, etc.) and the prize of the game balls It is possible to change the state to a specific gaming state (for example, a big hit state) in which the number of balls paid out is larger than the number of game balls inserted.

  More specifically, when a game ball wins the first start port 33a, the two LEDs 40a and 40b of the first symbol display device 40 are displayed in a variable manner, and the display of the LEDs 40a and 40b after the change is stopped is a preset light emission. A specific gaming state occurs when a combination of modes is obtained. For example, in the case of a light emitting mode in which both LEDs 40a and 40b are stopped in a red light emitting state, it indicates that a specific gaming state with a probable big hit (specific hit) is won, and both LEDs 40a and 40b are stopped in a blue light emitting state. In the case of the light-emission mode, it indicates that the player has won the special game state of normal big hit (non-specific hit), and in the case of the light-emission mode that both LEDs 40a and 40b stop in the light-emission state of different colors (You have lost the game).

  Similarly to the above, when the game ball wins the second start opening 33b, the two LEDs 40d, 40e of the first symbol display device 40 are displayed in a variable manner, and the display of the LEDs 40d, 40e after the change stop is preset. A specific gaming state occurs when a combination of light emission modes is obtained. For example, in the case of a light emitting mode in which both LEDs 40d and 40e are stopped in a red light emitting state, it indicates that a specific gaming state with a probable big hit (specific hit) is won, and both LEDs 40d and 40e are stopped in a blue light emitting state. In the case of the light emission mode, it indicates that the player has won the specific game state of the normal big hit (non-specific hit), and in the case of the light emission mode in which both LEDs 40d and 40e are stopped in the light emission states of different colors (You have lost the game).

  The variable winning device 32 is configured such that the large winning opening 32a is in a predetermined open state and the game ball is likely to win (a big hit state). Specifically, the special winning opening 32a of the variable winning device 32 is repeatedly opened a predetermined number of times (the number of rounds) with the passage of a predetermined time or a predetermined number of winnings in the open state as one round. Further, the number of times that the game ball has passed through the first start port 33a is held up to a maximum of 4 times, and the number of times of holding is displayed on the hold display section 40c. The number of times that the game ball has passed through the second start port 33b is also held up to 4 times, and the number of times of holding is displayed on the hold display section 40f. The hold display units 40c and 40f display a hold on a part of the display screen of the third symbol display device 42. However, the hold display units 40c and 40f may be lit using a hold lamp or the like.

  Further, as shown in FIG. 2, the game board 30 is provided with a plurality of rails 51 and 52 for guiding the game balls launched from the game ball launching device 38 (see FIG. 3) to the upper part of the game board 30. Thus, the game balls launched in accordance with the turning operation of the game ball launching handle 18 are guided to a predetermined game area 30a through a ball guide passage 49 (to be described later) of the plurality of rails 51 and 52. . The plurality of rails 51 and 52 are long metal strip members made of stainless steel, and are attached to the game board 30 in an inner and outer double. The inner rail 51 is formed in a substantially vertical elliptical shape except for about 1/4 of the upper side. The outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a ball guide passage 49 is formed by a portion (the left portion toward the left) where the rails 51 and 52 are parallel to each other at a predetermined interval. . The ball guide passage 49 is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 2). This prevents a situation in which the game ball once guided from the ball guide passage 49 between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage 49 again. It has become. Further, in a state in which the game board 30 is attached to the inner frame 12, the outer rail 52 is located at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 2: a portion corresponding to the tip portion of the outer rail 52). Is configured such that a return rubber 54 (a member indicated by a two-dot chain line in FIG. 2) provided on the inner frame 12 is located. Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back.

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. The pachinko machine 10 includes a main control device 261, a payout control device 311, a launch control device 312, a sub control device 262, a display control device 45, a power supply device 313, and the like. In the following, these devices will be described in detail individually.

  The main control device 261 of the pachinko machine 10 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic device. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. A RAM 503 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The RAM 503 has a configuration in which data can be retained (backed up) by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off. The RAM 503 temporarily stores various data and the like. It has a memory and area.

  That is, when the power is cut off due to the occurrence of a power failure or the like, the CPU 501 of the main control device 261 executes the normal processing to the end, so that the RAM 503 is when the power is turned off (including when a power failure occurs, and so on). It is only necessary to store and hold the contents of the counter buffer and the holding ball storage area, and the state of the pachinko machine 10 can be restored to the state before the power is turned off when the power is turned on again. Specifically, the RAM 503 has a dedicated backup area for storing values of registers, I / O, and the like for game information during normal processing when the power is turned off (including when a power failure occurs). There is no need to provide it. The N501 terminal (non-maskable interrupt terminal) of the CPU 501 is configured to receive a power failure signal S1 output from a power failure monitoring circuit 542, which will be described later, 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.

  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. The input / output port 505 includes a RAM erasing switch circuit 543, a payout control device 311, a firing control device 312, a sub control device 262, a first symbol display device 40, a second symbol display device 41, and other switches not shown. Etc. are connected. The main controller 261 also has a function of controlling the first symbol variation display on the first symbol display device 40 and the second symbol variation display on the second symbol display device 41.

  The payout control device 311 controls payout of prize balls and rental balls by a payout motor 358a. 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 is configured to hold (backup) data by supplying a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, like the RAM 503 of the main control device 261 described above. The RAM 513 includes a memory and an area for temporarily storing various data.

  The RAM 513 stores and holds information related to the state when the power is turned off in order to return the state of the pachinko machine 10 to the state before the power is turned off when the power is turned off due to a power failure or the like. In other words, the storage of the RAM 513 is executed when the power is turned off by the NMI interrupt process and the second half of the payout control process, and the storage information stored in the RAM 513 is restored in the power recovery process when the power is turned on. .

  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. Main controller 261, launch controller 312 and payout motor 358a are connected to input / output port 515, respectively.

The firing permission signal S7 is output to the main controller 261 on condition that all of the fired maintenance signals S6 to be performed are inputted.

  That is, the period during which the firing permission signal S7 is ON (high level) is a firing permission state, and the period during which the firing permission signal S7 is OFF (low level) is a firing non-permission state. That is, the main control device 261 has a firing control signal S8 (pulse signal) for controlling a launching solenoid (not shown) that launches a game ball during a period when the input firing permission signal S7 is ON (high level). The ball feed control signal S9 (pulse signal) for controlling the ball feed solenoid that sends the game ball to the launch rail 401 is repeatedly output to the launch control device 312 at a predetermined repetition period. The launch control device 312 drives and controls the launch device 229 based on the launch control signal S8 and the ball feed control signal S9, and a game ball is launched with an intensity corresponding to the amount of operation of the game ball launch handle 18. On the contrary, the main control device 261 does not output the firing control signal S8 and the ball feed control signal S9 to the firing control device 312 during the period when the input firing permission signal S7 is OFF (low level). The game ball is not fired by 229.

  The display control device 45 controls the variable display of the third symbol (decorative symbol) on the third symbol display device 42.

Further, an output port 529 is connected to the image controller 526 via a bus line 531, and a third symbol display device 42 which is a liquid crystal display device is connected to an output of the output port 529.

  The CPU 521 of the display control device 45 controls the decorative symbol display on the third symbol display device 42 based on the various commands transmitted by editing the various commands from the main control device 261 by the sub-control device 262. The ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 temporarily stores work data and flags used when the CPU 521 executes various programs. It is a memory for.

  The video RAM 524 is a memory for storing display data displayed on the third symbol display device 42, and the display contents of the third symbol display device 42 are changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as decorative symbols displayed on the third symbol display device 42. The image controller 526 adjusts the timings of the CPU 521, the video RAM 524, and the output port 529 to intervene in reading and writing data, and reads display data stored in the video RAM 524 from the character ROM 525 at a predetermined timing. It is displayed on the symbol display device 42.

  In addition, the power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 10. 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 an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like. Then, 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.

  As shown in FIG. 4, the main controller 261 includes a main control board 261a and a power supply monitoring board 261b separate from the main control board 261a in a board box 263 made of a transparent resin material or the like. . The power monitoring board 261b includes a power failure monitoring circuit 542 that monitors power interruption due to a power failure or the like, and a RAM erase switch circuit 543 connected to the RAM erase switch 323.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal S1 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 voltage of AC 24 volts with the power supply unit 541 and determines that a power failure (power failure) has occurred when the time when this voltage has become less than 24 volts exceeds, for example, 20 milliseconds. The power failure signal S1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal S1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute a power failure process (NMI interrupt processing).

  In addition, even after the time when the AC 5 volts monitored by the power supply unit 541 becomes less than 5 volts exceeds 20 milliseconds, the power supply unit 541 has a sufficient time to execute the power failure process. The control system is configured to maintain the output of 5 volts, which is the drive voltage of the control system, at a normal 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 for taking in the switch signal of the RAM erase switch 323 and clearing 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 S2 to the main control board 261a. 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 RAM 503 is cleared in the main controller 261, and the payout controller 311 is in the main controller. When the initialization command from H.261 is received, the data in the RAM 513 is cleared.

  By the way, in the third symbol display device 42 (liquid crystal display device), as shown in FIG. 5, three decorative symbol rows L, M, and R of left, middle, and right are set. For each of M and R, three decorative symbols, an upper decorative symbol, a middle decorative symbol, and a lower decorative symbol, are variably displayed.

  Further, as shown in FIGS. 6 to 8, the substrate box 263 includes another type of separate sealing portion 290 different from the sealing member 280. As shown in FIG. 8, the separate sealing portion 290 uses a breaking screw 291 to fix the box base 265 and the box cover 267 so as to prevent the sliding movement thereof. Specifically, as shown in FIG. 8B, in the state where the box base 265 and the box cover 267 are combined, the breaking screw 291 is inserted into the through hole 292 formed in the separate sealing portion 290 of the box base 265. Then, the box base 265 and the box cover 267 are fastened with the breaking screw 291 by screwing into a temporary hole (not shown) of the box cover 267. Also by this separate sealing portion 290, the box base 265 and the box cover 267 are fixed so as to prevent the sliding movement thereof. Note that a one-way screw may be used instead of the breaking screw 291.

  Further, the separate sealing portion 290 includes a fixed-release-destructed portion 293 that is broken to release the state in which the box base 265 and the box cover 267 cannot slide.

  The above-mentioned main control board 261a corresponds to the control board in the present invention, the above-mentioned board box 263 corresponds to the gaming machine board housing case in the present invention, and the above-mentioned box cover 267 corresponds to the first case body in the present invention. The above-described box base 265 corresponds to the second case body in the present invention, the above-described sealing member 280 corresponds to the sealing means in the present invention, and the above-described enclosure wall portion 283 includes the enclosure wall in the present invention. The above-described locking member 270 corresponds to the locking means in the present invention, the above-described bottomed storage portion 284 corresponds to the bottomed storage portion in the present invention, and the above-described locking member 285 is in the present invention. The caulking member 287 described above corresponds to the insertion member in the present invention, and the above-described separate sealing portion 290 corresponds to the separate sealing means in the present invention. And, first locking claw 285a as described above corresponds to the first locking portion in the present invention, the second locking claw 285b described above corresponds to the second locking portion in the present invention.

  Here, the sealing procedure of the substrate box 263 of Example 1 will be described.

  As shown in FIG. 8, a connector base (not shown) is screwed to a predetermined position inside the box base 265 via the opening 265a of the box base 265, and further, the main part is opened via the opening 265a of the box base 265. The control board 261a is inserted, and the main control board 261a is attached to a predetermined position inside the box base 265 by screwing.

  As shown in FIG. 8A, FIG. 9A, and FIG. 10A, the locking member 285 is inserted into the bottomed storage portion 284 of the box cover 267. As shown in FIG. 10B, the locking member 285 inserted into the bottomed storage portion 284 of the box cover 267 has its first locking claw 285a in the engagement hole 284a of the bottomed storage portion 284. It is in a locked state so that it cannot be removed from the bottomed storage portion 284.

  Then, the box cover 267 is put together so as to substantially cover the opening 265a of the box base 265, and as shown in FIG. 8A, the box base 265 and the box cover 267 are relatively moved in the longitudinal direction. As shown in FIG. 8B, the opening portion 265a of the box base 265 is brought into a position that is closed by the box cover 267 by sliding the portion 273 to the length of the extended portion 271b.

  Then, as shown in FIG. 8B, in a state where the box base 265 and the box cover 267 are combined, as shown in FIGS. 8B, 9C, and 10C, the box The caulking member 287 is inserted into each of the openings 286 of the two sealing portions 281 on the left side of the front surface of the base 265. As shown in FIG. 9D, the caulking member 287 inserted into the opening 286 of the sealing portion 281 is in a state of being locked with the locking member 285. Specifically, the second locking claw 285b of the locking member 285 is locked to the locking recess 287d of the caulking member 287.

  Further, as shown in FIG. 9 (d), the first supported portion 287 a of the caulking member 287 is supported by the support portion 285 c of the locking member 285 in the state of being locked with the locking member 285. Since the second supported portion 287b and the third supported portion 287c are supported by the respective support portions 281a of the sealing portion 281, the caulking member 287 is a locking member 285 of the bottomed storage portion 284. In this state, the three points are supported.

  Subsequently, as shown in FIG. 8B, the box base 265 and the box cover 267 are further attached by screwing the breaking screws 291 into two separate sealing portions 290 except for the middle of the three locations. Seal. Specifically, as shown in FIG. 8B, in a state where the box base 265 and the box cover 267 are combined, the through holes 292 formed in the two separate sealing portions 290 of the box base 265 are broken. Each of the screws 291 is inserted and screwed into a temporary hole (not shown) of the box cover 267, whereby the box base 265 and the box cover 267 are fastened by the breaking screw 291. When the tightening torque of a predetermined level or more is applied to the break screw 291, the screw head is broken and cannot be loosened. Thus, not only the sealing member 280 but also this separate sealing portion 290 fixes the box base 265 and the box cover 267 so as to prevent the sliding movement thereof.

  As shown in FIGS. 8 and 11, the breaking screw 291 whose screw head is broken is in a state of sinking in the through hole 292 of the sealing portion 281 of the box base 265, and the breaking screw 291 is illegal. Inaccessible.

  By doing so, the box base 265 and the box cover 267 cannot be opened. In addition, a plurality (six) of locking claws 271 provided on both sides in the longitudinal direction of the box base 265 are provided (six in number) provided on both sides of the box cover 267 in the longitudinal direction. ) To be locked to each of the locked portions 272, it is also possible to prevent a gap between the upper and lower surfaces of the board box 263 from being inserted by inserting a thin irregular tool.

  Next, the procedure for opening the substrate box 263 of Example 1 will be described.

  As shown in FIG. 8 (a), the defragmentation part 282 for the unlocking of the two sealing parts 281 of the box base 265 and the destructible part 293 for the unlocking of the two separate sealing parts 290, Each of them is cut and broken by a cutting tool (for example, a nipper or a blade).

  When the unlocking broken part 282 and the unlocking broken part 293 are cut (broken), the cut sealing part 281 and the separate sealing part 290 of the box base 265 are separated from the box base 265. Thus, the state in which the box base 265 and the box cover 267 cannot slide is released.

  Note that the fractured sealing portion 281 separated from the box base 265 remains integrally with the box cover 267 as the caulking member 287 is locked to the locking member 285 of the bottomed storage portion 284. In this state, the slide movement impossible state with 267 is canceled. It should be noted that the separate sealing portion 290 after being broken remains in the box cover 267 integrally by fastening the breaking screw 291.

  As described above, the pachinko machine 10 according to the first embodiment includes the box base 265 to which the main control board 261a is attached and the box cover 267 to be combined with the box base 265, and the main control board 261a is attached to the box base 265. The main control board 261a is accommodated in the internal space formed by aligning the box cover 267 with the control board mounting surface side of the box base 265, and the box base to which the main control board 261a is attached. 265 includes a sealing member 280 that seals the box base 265 and the box cover 267 so that the box cover 267 cannot be opened in a state where the box cover 267 is aligned with the mounting surface side of the main control board 261a. The box base 265 and the box cover at the place where 280 exists Since the surrounding wall portion 283 surrounding the boundary surface BL with the H.267 is provided, the boundary surface BL between the box base 265 and the box cover 267 where the sealing member 280 exists is provided by the surrounding wall portion 283 of the box cover 267. As shown in FIG. 11, an illegal thin member (for example, a flat-blade screwdriver D) cannot be inserted from the side surface where the sealing member 280 of the substrate box 263 exists, and the substrate box 263. Since it can only be accessed from the front side, it can be difficult to insert an unauthorized thin member (for example, a flathead screwdriver D) into the boundary surface BL, and an unauthorized thin member can be inserted into the boundary surface BL. It can be difficult to separate the box base 265 and the box cover 267 at the place where the sealing member 280 exists. As a result, the pachinko machine 10 using the board box 263 (a gaming machine board housing case) that can reduce unauthorized opening can be provided.

  Further, the enclosure wall portion 283 is a crank-like wall portion 283a that is bent in a right-angled direction from the wall direction in a cross-sectional view and then bent again so as to extend in the wall direction. A stronger enclosure can be realized than in the case of a rectangular enclosure, and it is excellent in anti-fraud measures.

  In addition, the locking member 270 of the board box 263 has the box base 265 or the box cover 267 in a state where the box cover 267 is aligned with the mounting surface side of the main control board 261a of the box base 265 to which the main control board 261a is attached. The box base 265 and the box cover 267 are locked by sliding at least one of them in a predetermined direction of the mating surface. The sealing member 280 seals the box base 265 and the box cover 267 locked by the locking member 270 so that they cannot be opened. Therefore, since the box base 265 and the box cover 267 are sealed so as not to be opened by the sealing member 280, it is possible to reduce the unauthorized opening of the substrate box 263. In this sealed state, the box base 265 and the box cover 267 are slidably locked by the locking member 270, and the box base 265 and the box cover 267 cannot be opened in the opposite direction perpendicular to the sliding direction. It is possible to reduce unauthorized opening of the substrate box 263.

  In addition, a plurality of locking members 270 (6 on each side) are disposed over both sides (upper surface and lower surface) of the box base 265 in parallel to the sliding direction (longitudinal direction). A plurality (6 on each side) of the claw 271 and the sides (upper surface and lower surface) parallel to the sliding direction (longitudinal direction) of the box cover 267 are arranged over the side direction. The locking claw 271 includes a protruding portion 271a protruding from the box base 265 toward the box cover 267, and a sliding direction (longitudinal direction of the box base 265) from the protruding portion 271a. ) Having an extended portion 271b extending to the engagement portion 272, and the locked portion 272 includes an opening 272a into which the flange 273 is inserted, and a state in which the flange 273 is inserted into the opening 272a. Since at least one of the box base 265 or the box cover 267 is slid and moved, the extending portion 271b is provided with a retaining portion 272b. Therefore, the sides of the box base 265 are parallel to the sliding direction on the box base 265. A plurality (six sides) of the locking claws 271 arranged along the direction are arranged along the side direction at both sides parallel to the sliding direction of the box cover 267 (each Since the box base 265 and the box cover 267 are sealed so that they cannot be opened by the sealing member 280, both sides of the box base 265 are predetermined. It is slidably locked by a plurality of (six sides) locking claws 271 arranged over the length, and the thin illegal tool is attached to the box base 265 and the box. It is possible to reduce a gap between the box base 265 and the box cover 267 by inserting it between the box cover 267 and the box base 265 and the box cover 267. Formation and opening can be reduced.

  Further, the sealing member 280 is fixed so as to suppress the sliding movement of the box base 265 and the box cover 267, and when the fixing-released fractured portion 282 of the sealing member 280 is broken, the box base The state in which the slide movement disabled state of the H.265 or the box cover 267 is released. Therefore, it can be seen that the substrate box 263 has been opened by looking at the breakage marks of the broken portion 282 for fixation release.

  The sealing member 280 includes a bottomed storage portion 284 formed at a predetermined position of the box cover 267, and a locking member 285 inserted into the bottomed storage portion 284 and locked therein. A sealing portion 281 having an opening 286 formed at a position on the box base 265 corresponding to the bottomed storage portion 284 of the box cover 267 so that the locking member 285 does not come out, and a bottomed storage portion The caulking member 287 is inserted into the opening 286 and locked with the locking member 285 in a state where the locking member 285 is locked to the H. 284 and the box base 265 is slid to the box cover 267. And. In addition, the sealing member 280 is incapable of relative sliding movement between the box cover 267 and the box base 265 because the caulking member 287 is inserted into the opening 286 and locked with the locking member 285. In addition, the caulking member 287 after being locked cannot be removed. The bottomed storage part 284 includes an enclosure wall part 283. Therefore, since the boundary surface BL of the box cover 267 and the box base 265 at the location where the sealing member 280 exists is surrounded by the surrounding wall portion 283 of the bottomed storage portion 284, the boundary surface BL is illegal. It can be difficult to insert the thin member, and it is difficult to separate the box cover 267 and the box base 265 at the place where the sealing member 280 exists by inserting an illegal thin member into the boundary surface BL. can do. As a result, the pachinko machine 10 using the substrate box 263 that can reduce unauthorized opening can be provided. In addition, since the breakage portion 282 for fixing release is formed in the connecting portion 288 that connects the main body portion 265b of the box base 265 and the sealing portion 281, The cover 267 and the box base 265 can be moved relative to each other, and the box cover 267 and the box base 265 can be opened. In addition, since the sealing part 281 remains in the box cover 267, it can be seen that the seal was opened due to the fracture mark.

  Further, the caulking member 287 has a substantially inverted T-shape, and a first supported portion 287a provided on the insertion tip end side and a second supported portion provided on two places on the insertion rear end side. A portion 287b and a third supported portion 287c. The locking member 285 includes a support portion 285 c that supports the first supported portion 287 a of the caulking member 287. The sealing part 281 of the box base 265 includes a support part 281a that supports the second supported part 287b and the third supported part 287c in a state where the caulking member 287 is inserted into the opening part 286. Therefore, in a state where the caulking member 287 is inserted and locked into the opening 286 of the sealing portion 281, the caulking member 287 is supported at three points of the first supported portion 287 a to the third supported portion 287 c. Therefore, it is difficult for the posture of the caulking member 287 to be changed with respect to the unauthorized insertion of the thin member, and deformation of the locking member 285 due to the unauthorized insertion of the thin member can be reduced.

  The sealing member 280 is a different type of sealing means, and further includes a separate sealing portion 290 formed by a break screw 291. The separate sealing portion 290 slides the box cover 267 and the box base 265 on its slide. It is fixed so as to prevent the movement, and is provided with a fixed-release-destructed portion 293 that is broken so as to release the state in which the box cover 267 and the box base 265 cannot slide. Therefore, the substrate box 263 can be sealed not only by the sealing member 280 but also by another sealing part 290 of a different type from that, and can be more difficult to open. In addition, when the delocked part 282 for fixing release of the sealing member 280 and the destructible part 293 for fixing release of the separate sealing part 290 are broken, the state in which the box cover 267 and the box base 265 cannot slide is released. Is done. Therefore, it can be seen that the substrate box 263 has been opened by looking at the breakage marks of the debonded parts 282 and 293 for release.

  The locking member 285 includes a first locking claw 285a for locking the locking member 285 inside the bottomed storage portion 284, and a second locking for locking the caulking member 287. Since the first locking claw 285a is easier to deform or break than the second locking claw 285b, the box base 265 and the box cover 267 at the location where the sealing member 280 exists are provided. Even if an improper thin member is inserted into the boundary surface BL and the box base 265 and the box cover 267 at that location can be separated, the first locking claw 285a is deformed or broken, Since the member 285 moves in the pulling direction together with the caulking member 287 after being locked, it is possible to reduce the second locking claw 285b of the locking member 285 from being bent and deformed. Further, although the locking member 285 can move with respect to the bottomed storage portion 284 within a predetermined range in the pulling direction together with the caulking member 287 after locking, the caulking member 287 after locking cannot be removed. Therefore, the substrate box 263 cannot be opened. As a result, a gaming machine using the board box 263 that can reduce unauthorized opening can be provided.

  Further, as shown in FIG. 7, another sealing portion 290 (a caulking structure in which a box is integrally formed by a screw-in type) is arranged next to the sealing member 280 (an insertion type caulking structure by a locking claw). Since the structure has a structure, the separate sealing part 290 (screw-in type) is sandwiched between the sealing member 280 having a separate structure and the space around the separate sealing part 290 is eliminated. It is difficult for the 290 breaking screw 291 to be rotated by an unauthorized act. Further, the sealing member 280 (insertion type caulking) has a caulking structure (separate sealing portion 290) in which a box is integrally formed adjacent to the sealing member 280, so that there is no gap with respect to deflection due to an external force such as illegal separation. Therefore, it is possible to improve the anti-fraud function by compensating for the weak portions of the insertion type (sealing member 280) and the screwing type (separate sealing part 290) using the locking claws.

  Next, the substrate box 263 of the pachinko machine 10 according to the second embodiment will be described with reference to FIG.

  FIGS. 12A and 12B are a left side view and a front view of the substrate box 263 of the second embodiment.

  As shown in FIG. 12, the box cover 267 of the second embodiment is different from the first embodiment described above in that, for example, two cutout portions 283b are formed in the surrounding wall portion 283.

  As shown in FIG. 11, when an illegal thin member (for example, a flat-blade screwdriver D) is inserted at a location between the box base 265 and the box cover 267 in the sealing member 280 of the substrate box 263, the box cover A part of the surrounding wall portion 283 of 267 (a portion sandwiched between the two cutout portions 283b in the surrounding wall portion 283) is easily broken.

  In addition, the notch part 283b mentioned above is equivalent to a fracture | rupture induction | guidance | derivation part to this invention.

  As described above, according to the substrate box 263 of the second embodiment, the surrounding wall portion 283 of the box cover 267 includes the notch portion 283b on the wall surface, and therefore, the sealing member 280 is an unauthorized thin member. When (for example, a flathead screwdriver D) is inserted, the cutout portion 283b of the surrounding wall portion 283 is broken, and it can be seen that the substrate box 263 has been opened by visually checking the broken portion.
