The positioning projection 25 of the back cover 20 is inserted into and engaged with the other (see FIG. 16), and another pair of corners on the diagonal line (for example, the upper left and lower right in FIG. The fixing holes 36 at the corners) and the fixing holes 26 of the back cover 20 are superposed and screwed together with screws 37. As described above, in the present embodiment, in consideration of the efficiency of the assembly work, a method is adopted in which the sub control board 30 is positioned on the back cover 20 at two locations and fixed by screwing at two locations. .

  On the front side of the back cover 20, there is a rectangular accommodating portion 23 that accommodates the sub control board 30. As shown in FIGS. 7 and 11, positioning protrusions 25 and fixing holes 26 are formed in the accommodating portion 23 in accordance with the positions where the corner portions of the sub-control boards 31 and 32 are placed. In the present embodiment, as described above, the positioning protrusions 25 and the fixing holes 26 are provided at two positions for each of the sub control boards 31 and 32. The accommodating portion 23 is provided with a plurality of vent holes 27 for releasing heat generated in the sub-control board 30 to the outside.

  In addition, hinge portions 21 that engage with the hook portions 11 of the front cover 10 are formed on the left and right ends of the upper outer edge of the housing portion 23, respectively, and the left and right ends of the lower outer edge of the housing portion 23 are formed on the left and right ends, respectively. A screw hole 22 that overlaps with the screw hole 12 of the front cover 10 is formed. Further, the back cover 20 is formed with four screw holes 24 on the outer edge of the housing portion 23 for mounting inside the housing of the slot machine 100, and the sub-board housing case is formed through the screw holes 24. 220 is screwed inside the housing of the slot machine 100.

  The front cover 10 has a box shape that is open on the back (rear) side, and is provided with a plurality of openings 13 for connecting to the connector part 33 of the sub-control board 30 from the lower center part to the right end part. Further, the front cover 10 is provided with a plurality of vent holes 14 so as to release heat generated in the sub-control board 30 to the outside.

The screw hole portions 12 that overlap with the screw hole portions 22 of the back cover 20 are formed.

  Further, as shown in FIGS. 8 and 9, two pressing pieces 41 are formed in the vicinity of the opening hole 13 on the back surface of the front cover 10. As shown in FIGS. 12 to 14, the holding piece 41 is a protruding piece for holding the sub-control board 32 and fixing the sub-control board 32, and is pushed to a predetermined position on the back surface of the front cover 10. By providing the stop piece 41, the sub control board 32 can be firmly fixed to the back cover 20.

  In order to improve the assembly work, in the method of reducing the number of parts when fixing the control board to the board storage case, positioning the control board on the back cover in two places, and fixing by screwing in two places, When pulling out the external connector from the control board, the control board may not be firmly fixed to the board storage case and may float, and in this case, the control board may be damaged by bending, The retaining piece 41 provided on the back surface of the front cover 10 is an improvement measure made to prevent this problem. That is, in this embodiment, in order to improve the assembly work as in the conventional case, the sub-control board 30 is firmly attached to the back cover while the number of parts when the control board is fixed to the board storage case is reduced. Therefore, when the connector is pulled out from the control board, the problem that the sub-control board 30 floats or the sub-control board 30 is damaged can be solved.

  Specifically, in the state where the sub control board 30 is fixed to the back cover 20 and the front cover 10 and the back cover 20 are combined, as shown in FIGS. The holding piece 41 is arranged so that the connector portion 33 is sandwiched between the fixed position (the position of the fixed hole 36). That is, the holding piece 41 is separated by a predetermined distance in the direction from the connector portion 33 (the connector portion 33 closest to the positioning hole 35 when a plurality of connector portions 33 are adjacent) toward the positioning hole 35. It is arranged at the position. This is because when the external connector is pulled out from the sub-control board 32, the vicinity of the connector portion 33 and the positioning portion 35 is likely to float.

  Further, as shown in FIGS. 12 to 14, the holding piece 41 has a tapered shape in which the cross section becomes narrower from the base side to the tip side of the front cover 10, and the tip portion is sub-controlled. The one end edge of the board | substrate 32 is contact | abutted. That is, the holding piece 41 holds the control board 32 in the direction opposite to the direction in which the external connector is pulled out from the sub-control board 32. Therefore, in addition to the force with which the screw 37 fixes the sub control board 30 to the back cover 20, the holding force of the holding piece 41 also acts, so that the restraining function for the sub control board 30 is further strengthened.

  As described above, according to the sub-board storage case 220 of the present embodiment, the holding piece 41 formed on the front cover 10 has a function of holding the sub-control board 30. Even if the number of parts when fixing is reduced and fixed, the control board can be firmly fixed to the board storage case with a simple configuration. As a result, even if the connector is inserted into and removed from the control board, the control board can be prevented from floating or deformed.

  In the present embodiment, the restraining function by the pressing piece 41 is strengthened only for the sub-control board 32, but similarly, the pressing piece 41 is provided for the sub-control board 31. The stopping function by 41 may be strengthened.

  In the present embodiment, the substrate storage case of the present invention is applied to the sub-control board. However, the present invention is not limited to this, and other control units may be used. Of course. For example, when the connector is inserted into and removed from the main control board, the control board may be applied to the main control board if there is a risk of floating or deformation. Of course, the present invention may be applied to a power supply board or a relay board as a control board related to a game.

  In the present embodiment, the present invention is applied to a system in which the control board is positioned at two positions on the back cover and fixed by screwing at two positions. However, the control board is screwed to the back cover at four positions. The present invention may be applied to a fixing method. Even in this case, the restraining function for the control board is further strengthened.

  Further, the sub-board storage case 220 described in the present embodiment can be traded in a form mounted on the slot machine 100, or can be traded as a sub-board storage case 220 alone.

It is a rear view of the front cover 10A of the storage case 220A. 21A is a sectional view taken along line JJ in FIG. 18, and FIG. 21B is an external perspective view of the holding piece 42. FIG.

  As shown in FIGS. 18 to 20, the sub-board storage case 220 </ b> A has two pressing pieces 42 formed on the back cover 20 </ b> A, not the front cover 10 </ b> A. The holding piece 42 is arranged at substantially the same position as the position where the holding piece 41 holds the control board 32 in the above embodiment. That is, the holding piece 42 is arranged so that the connector portion 33 is sandwiched between the holding piece 42 and the fixed position (position of the fixing hole 36) screwed by the screw 37.

  The holding piece 42 is a protruding piece for holding the sub-control board 32 and fixing the sub-control board 32, and as shown in FIG. 21 (b), its tip (upper end in FIG. 21 (b)). The claw portion 42a that engages with the sub-control board 32 is formed inward (sub-control board 32 side). Then, as shown in FIGS. 18 and 21A, the claw portion 42a engages with one end edge of the sub-control board 32 placed on the back cover 20A, so that the holding piece 42 becomes an external connector. The control board 32 is pressed in the direction opposite to the direction in which the control board 32 is pulled out from the sub-control board 32. Therefore, in addition to the force with which the screw 37 fixes the sub control board 30 to the back cover 20, the holding force of the holding piece 42 also acts, so that the restraining function for the sub control board 30 is further strengthened.

  As described above, according to the sub-board storage case 220A of the first modified example, the pressing piece 42 formed on the back cover 20A has a function of pressing the sub-control board 30, so that the control board is fixed to the board storage case. Even if the number of parts is reduced and fixed, the control board can be firmly fixed to the board storage case with a simple configuration. As a result, even if the connector is inserted into and removed from the control board, the control board can be prevented from floating or deformed.

(Second modification)
Next, a second modification of the sub-board storage case will be described with reference to FIGS. In the present modification, only the configuration and functions different from those of the above-described embodiment and the above-described modification will be described, and with regard to the other configurations and functions, the same portions are denoted by the same reference numerals and description thereof will be omitted.

  Similar to the first modification, the sub-board storage case 220B of the second modification has a configuration in which a back cover is provided on the back cover instead of the front cover. However, the shape of the stop piece is different from that of the first modification. The other points are substantially the same as those of the sub-board storage case 220A. Here, FIG. 22 is a front view of the back cover 20B of the sub-board storage case 220B with the sub-control board 30B mounted thereon, FIG. 23 is a front view of the back cover 20B of the sub-board storage case 220B, and FIG. It is an external appearance perspective view of the board | substrate 32B. 25A is a cross-sectional view taken along the line KK in FIG. 22, and FIG. 25B is an external perspective view of the holding piece 43.

  As shown in FIGS. 22 and 23, the sub-board storage case 220B has two retaining pieces 43 formed on the back cover 20B. The holding piece 43 is disposed at substantially the same position as the position where the holding piece holds the control board 32 in the embodiment and the modification. That is, the pressing piece 43 is arranged so that the connector portion 33 is sandwiched between the pressing piece 43 and a fixed position (position of the fixing hole 36) screwed by the screw 37.

  The holding piece 43 is a protruding piece for holding the sub-control board 32 and fixing the sub-control board 32, and as shown in FIG. A claw 43a is formed. The claw 43a protrudes toward the outer side of the holding piece 43, and is engaged with one end edge of the sub-control board 32B placed on the back cover 20B as shown in FIGS. 22 and 25A. The holding piece 43 holds the control board 32 in the direction opposite to the direction in which the external connector is pulled out from the sub-control board 32. That is, the claw 43a having elasticity is pressed inward, the claw 43a is inserted into the hole 34 formed in the sub-control board 32B, the sub-control board 32B is placed on the back cover 20B, and then the claw 43a is opened. As a result, the claw 43a engages with the sub-control board 32B, and the holding piece 43 holds the sub-control board 32B. Therefore, in addition to the force with which the screw 37 fixes the sub control board 32B to the back cover 20, the holding force of the holding piece 43 also acts, so that the restraining function for the sub control board 32B is further strengthened.

  As described above, according to the sub-board storage case 220B of the second modified example, the pressing piece 43 formed on the back cover 20B has a function of pressing the sub-control board 32B, so that the control board is fixed to the board storage case. Even if the number of parts is reduced and fixed, the control board can be firmly fixed to the board storage case with a simple configuration. As a result, even if the connector is inserted into and removed from the control board, the control board can be prevented from floating or deformed.

(Third Modification)
Next, with reference to FIGS. 26 and 27, a third modification of the sub-board storage case will be described. In the present modification, only the configuration and functions different from those of the above-described embodiment and the above-described modification will be described, and with regard to the other configurations and functions, the same portions are denoted by the same reference numerals and description thereof will be omitted.

  The sub-board storage case 220C of the third modified example has a configuration in which a pressing piece is provided on the back cover, not the front cover, as in the above-described modified example, but the positioning hole and the fixing hole formed in the back cover. The position is different from the above embodiment and the above modification. Here, FIG. 26 is a front view of the back cover 20C of the sub-board storage case 220C with the sub-control board 30C placed thereon, and FIG. 27 is a front view of the back cover 20C of the sub-board storage case 220C.

  As shown in FIG. 26, the position of the positioning hole 25 and the fixing hole 26 is reversed in the sub-control board 32C as compared with the sub-control boards of the above-described embodiment and the modified example (FIGS. 10 and 18). , See FIG. That is, in the state where the rectangular sub-control board 32C is placed on the front side of the back cover 20C, the positioning holes 35 are arranged at the upper left and lower right corners, and the fixing holes 36 are arranged at the lower left and upper right corners. A positioning hole 35 and a fixing hole 36 are formed.

  Correspondingly, as shown in FIGS. 26 and 27, the back cover 20 </ b> C also has the positioning protrusions 25 and the fixing holes 26 formed in reverse positions as compared with the back cover of the embodiment and the modified example. (See FIGS. 11, 19, and 26). That is, when the back cover 20C is viewed from the front side (front side), the positioning projections 25 and the fixing holes 26 are arranged so that the positioning protrusions 25 are arranged at the upper left and lower right corners, and the fixing holes 26 are arranged at the lower left and upper right corners. Is formed.

  Further, the back cover 20C is formed with a pressing piece 42 (see FIG. 21B) in the vicinity of the positioning hole 25 formed in the lower right corner when the back cover 20C is viewed from the front side (front side). Has been. As described above, the stopper piece 42 is formed with a claw portion 42a that engages with the sub-control board 32B at the tip (upper end in FIG. 21B) facing the inner side (sub-control board 32B side). ing. Thus, in this modification, unlike the said embodiment and the said modification, there is one holding piece. This is because when the external connector is pulled out from the sub control board 32C, the vicinity of the connector portion 33 and the positioning portion 35 is likely to float, and it is necessary to determine the position of the holding piece 42 in consideration of both areas. In the present modification, the vicinity of the connector portion 33 and the positioning portion 35 is substantially the same region, so that the sub-control board 32C is pressed at one position of the above position. That is, in the present modification, the connector portions 33 arranged on the two sides can be sandwiched between the two fixing screws 37 and the one holding piece 42.

  The claw portion 42a engages with one end edge of the sub control board 32C placed on the back cover 20C so as to press the control board 32C in the direction opposite to the direction in which the external connector is pulled out from the sub control board 32C. It has become. Therefore, in addition to the force by which the screw 37 fixes the sub control board 32C to the back cover 20, the holding force of the holding piece 42 also acts, so that the restraining function for the sub control board 30 is further strengthened.

  As described above, according to the sub-board storage case 220C of the third modified example, the holding piece 42 formed on the back cover 20C has a function of holding the sub-control board 32C, and thus the control board is fixed to the board storage case. Even if the number of parts is reduced and fixed, the control board can be firmly fixed to the board storage case with a simple configuration. As a result, even if the connector is inserted into and removed from the control board, the control board can be prevented from floating or deformed.

  Further, according to the sub-board storage case 220C of the third modified example, the positioning position and the fixing position when fixing the sub-control board 32C to the back cover 20C are formed in consideration of the connector arrangement position, so that one pressing The sub-control board 32C can be held by the stop piece 42, and the number of work steps can be reduced.

  In the substrate storage case of the embodiment and the modified example, the pressing piece is formed on either the front cover or the rear cover, but the present invention is not limited to this, and the pressing piece May be formed on both the front cover and the back cover. In this case, the restraining function for the control board is further strengthened.

  Further, in the substrate storage case of the embodiment and the modified example, the pressing piece is formed integrally with either the front cover or the rear cover, but separately, the pressing piece is attached to the front cover or the rear cover. It may be configured to be detachable from any of the covers. In this case, since the holding piece can be retrofitted, the same function as the board storage case of the present invention can be provided only by adding the holding piece to the conventional board storage case.

  Further, in the embodiment and the modification described above, the case where the control board is fixed to the back cover has been described. On the contrary, the case where the control board is fixed to the front cover is also described. Is applicable. That is, while the control board is fixed to the front cover, a pressing piece formed on the front cover or the back cover may hold the control board.

  In the above embodiment, the present invention is applied to a slot machine where medals are paid out. However, the present invention is not limited to this, and may be applied to a pachinko machine using a game ball. That is, the game ball is directed to the game area based on the game board in which the game area is formed, the launch handle device (operation knob) that accepts an operation for launching the game ball, and the operation accepted by the launch handle device. The invention may be applied to a substrate storage case of a pachinko machine that includes a launching device that bombards, and a privilege granting means that gives a predetermined privilege by winning a winning game ball entering a predetermined prize opening. .

  The pachinko machine will be described below.

  For example, as shown in FIG. 28, a pachinko machine 700 has a handle 710 for a player to launch a pachinko ball as a game ball, a tray 720 into which a pachinko ball launched by an operation on the handle is introduced, a pachinko ball A circular game area 730 is provided.

  A nail (not shown) is arranged in the game area, and a pachinko ball falling from the upper part of the game area falls to the lower part of the game area while colliding with the nail and changing its direction. A prize opening 740 is arranged in the game area, and when a pachinko ball enters the prize opening 740, a predetermined privilege is given to the player.

  In the present embodiment, this privilege is a jackpot lottery execution. Winning in the jackpot lottery gives players the chance to pay out a number of pachinko balls. An effect device 750 is provided in the center of the game area 730. The effect device 750 is also a variable display device that variably displays a predetermined symbol (identification information), and not only displays the effect image, but also when a winning combination is won in the lottery described above, A symbol (for example, 777) is also displayed.

  FIG. 29 is a functional block diagram of a control system of the pachinko machine 700. The pachinko machine 700 has a control unit 800. The control unit 800 includes a processing unit 810 such as a CPU, a random number generation unit 820 that generates random numbers, a storage unit A830 such as a RAM, and a storage unit B840 such as a ROM. The sensor 860 is a sensor that is provided at the winning opening and detects the entrance of a pachinko ball. Other devices 870 indicate other devices (lamps, pachinko ball payout devices, etc.).

  The processing means 810 determines whether or not the big winning lottery execution condition is satisfied. The condition for executing the jackpot lottery is established when the sensor 860 detects that a pachinko ball has entered the winning opening. The processing means 810 acquires a random number value from the random number generation means 820 and stores it in the storage means A830 when the condition for executing the jackpot lottery is satisfied.

  The random number value is sequentially stored with the upper limit number of times of storage determined in advance as the upper limit every time the execution condition of the jackpot lottery is satisfied. For example, four lottery results are stored. When four random numbers are stored, the new random value is discarded. The processing unit 810 performs a jackpot lottery process based on the random number value on the condition that the random number value is stored in the storage unit A830. When the random number values for a plurality of times are stored in the storage unit A830, the oldest one is selected in order.

  When the lottery result is a jackpot, the rendering device 750 displays identification information corresponding to the jackpot, the bonus game is started, and the player is given a chance to pay out a large number of pachinko balls.

<Effect of embodiment>
As described above, according to the game board substrate storage case according to the embodiment, the first cover member (for example, the control board (for example, the sub-control board 30) related to the game can be separated). The control is performed in the internal space formed by combining the first cover member and the second cover member while being fixed to either the front cover 10) or the second cover member (for example, the back cover 20). A gaming board substrate storage case (for example, sub-board storage case 220) for storing a substrate, and a pressing piece (for example, the pressing pieces 41, 42, 43) for holding the control board is connected to the first board. The cover member or the second cover member is provided on the inner space side.

  As described above, since the holding piece provided on the cover member of the gaming board substrate storage case has a function of holding the control board, the number of parts when fixing the control board to the board storage case is reduced and fixed. Even with this method, there is a case where the control board can be firmly fixed to the board storage case with a simple configuration.

  As an example, the control board includes a connector connection portion (for example, a connector) through which an external connector can be inserted and removed through an opening hole (for example, the opening portion 13) provided in the first cover member or the second cover member. 33), and the pressing piece is configured to hold the control board in a direction opposite to a direction in which the external connector connected to the connector connecting portion is pulled out. Thereby, even if the connector is inserted into and removed from the control board, it may be possible to prevent the control board from floating or deforming.

  In this case, the holding piece is configured to hold in the vicinity of the connector connecting portion. Thereby, since the restraining force of the pressing piece is further strengthened, even if the connector is inserted into and removed from the control board, it may be possible to reliably prevent the control board from floating or deforming.

  As an example, the holding piece is configured to hold an outer edge of the control board. Thereby, the place where the control board is easily deformed may be fixed.

  As an example, the control board has a rectangular shape, and is fixed to the first cover member or the second cover member in the vicinity of at least one corner of the rectangle. From the fixed position where the control board is fixed (for example, the position fixed with the screw 37) toward the corner portion (for example, the position where the positioning projection 25 and the positioning hole 35 overlap) that is not the fixed position of the rectangle. A position separated by a predetermined distance is configured to be stopped. This prevents the control board from floating or deforming even if the connector is inserted into or removed from the control board because the holding piece holds the control board against the corners that are not fixed. May be possible.

  In this case, as an example, the fixed position is in the vicinity of each corner on a pair of diagonal lines of the rectangle, and the pressing piece is not the fixed position of the rectangle from the fixed position of the control board. Each position separated by a predetermined distance in the direction of the two corners is configured to be pressed. As a result, the holding pieces respectively hold the control board against the two corners that are not fixed, so that the control board may be more reliably fixed to the board storage case.

  In this case, as another example, the fixed position is in the vicinity of each corner on a pair of diagonal lines of the rectangle, and the holding piece is in the vicinity of any one corner that is not the fixed position of the rectangle. Configured to hold down. As a result, since the holding piece holds the control board against one corner that is not fixed, the control board may be fixed to the board storage case with a small number of holding pieces. .

  Further, as an example, the connector connecting portion is configured to be provided between a position where the pressing piece holds the control board and a fixed position where the control board is fixed. As a result, when the connector is inserted into or removed from the control board, the holding piece holds down the place where the control board floats or deforms easily, so that the control board can be securely fixed to the board storage case. is there.

  Moreover, according to the game stand which concerns on embodiment, it is set as the structure provided with the board | substrate storage case for game machines mentioned above. As a result, the holding piece provided on the cover member of the game board substrate storage case has a function of holding the control board, so that the number of parts when fixing the control board to the board storage case is reduced and fixed. Even so, there may be a case where it is possible to provide a game machine that can firmly fix the control board to the board storage case with a simple configuration.
