When at least one case body is moved or moved in a direction in which the second case bodies are separated from each other, the second case body abuts on the trace portion and separation is prevented. A gaming machine characterized by

In the gaming machine of means 1, separation of the first case body and the second case body is prevented by setting the first fixing portion and the second fixing portion to a fixed state. As a result, it is possible to suppress the act of opening the board box and performing fraud on the control board. In addition, a release portion that is easier to break than the second fixed portion is provided, and the state in which the first case body and the second case body are fixed is released by destroying the release portion. Can be released relatively easily. Therefore, when the control board is inspected at the game hall, the workability of the release work when releasing the fixation by the fixing means is improved.

In the above configuration, even if the release portion is destroyed, the combination of the first fixing portion and the second fixing portion remains in the first case body as a trace portion, and the first case body and the second case body are separated even if the first case body is separated. The separation of the two case bodies is prevented by the two case bodies coming into contact with the trace portion. Thereby, even if a cancellation | release part is destroyed, both case bodies cannot be isolate | separated completely and the further destruction of a 1st case body, a 2nd case body, etc. will be needed. Therefore, the act of separating the first case body and the second case body from each other becomes complicated for an unauthorized person, and the act of illegally opening the board box can be suppressed. Further, even if the substrate box is illegally opened, not only the release portion but also a portion destroyed in the substrate box exists.

  The main control board 91 includes a CPU that performs main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, and the like. In the present embodiment, the CPU, ROM, and RAM are integrated into one chip on the CPU chip 93. Although not described in detail, an input / output driver IC chip 94 and a latch IC chip 95 are mounted. Although not shown, the main control board 91 is mounted with various elements such as capacitors and resistors. Furthermore, a plurality of connectors 96 are mounted on the main control board 91.

  In the main control board 91, various elements such as the CPU chip 93 and the connector 96 are all mounted on the same plate surface and soldered on the opposite plate surface. That is, the main control board 91 has one plate surface as an element mounting surface 97 and the other plate surface as a solder surface. The solder surface is a surface on which soldering portions of various elements mounted on the element mounting surface 97 are provided, but a circuit pattern may be formed on the solder surface.

  The substrate box 92 includes a front case body (box cover) 101, a back case body (box base) 102, and an intermediate case body (middle plate) 103 as a plurality of case bodies. The front case body 101, the back case body 102, and the intermediate case body 103 are transparent so that the element mounting surface 97 and the solder surface of the main control board 91 accommodated in the board box 92 can be seen from the outside of the board box 92. It is formed with the material which has. Specifically, it is formed of a colorless and transparent polycarbonate resin, but is not limited thereto, and may be an acrylic resin or the like.

  By combining the front case body 101, the back case body 102, and the intermediate case body 103, as shown in FIGS. 7A and 7B, the substrate box 92 is formed in a square box shape (substantially rectangular parallelepiped shape). And has a predetermined internal space. Specifically, as shown in FIG. 8, the front case body 101 is formed such that the front side peripheral edge 104 that defines the peripheral edge of the front case body 101 and the front side peripheral edge 104 bulge to one side. The bulging part 105 is integrally formed. Due to the front side peripheral edge 104 and the bulging portion 105, the front case body 101 has a substantially rectangular parallelepiped shape opened to the side opposite to the bulging side of the bulging portion 105. The bulging portion 105 has a rectangular shape when viewed from the front, and a long hole 106 extending along the long side is formed on one long side. The long hole portion 106 is surrounded by the front peripheral edge portion 104 and the partition wall 107 of the bulging portion 105.

  An intermediate case body 103 is screwed to the front case body 101 from the back side so as to close the long hole portion 106 (fixed in a detachable state), and the front case body from the back side. A main control board 91 is screwed to 101 (fixed in a detachable state). The screws of the main control board 91 to the front case body 101 are fixed from the solder surface side of the main control board 91, and various elements mounted on the element mounting surface 97 of the main control board 91 are the main control. It is accommodated in a region between the substrate 91 and the front case body 101.

  The intermediate case body 103 is formed with a plurality of through-hole portions 108 in a one-to-one correspondence with a predetermined group of connectors 96 formed on the main control board 91, and a predetermined connector formed on the main control board 91. 96 enters the corresponding through hole 108. The connector 96 is exposed on the surface side of the front case body 101. The position of the predetermined connector 96 on the main control board 91 may be changed for each model. In such a situation, the intermediate case body 103 is changed for each model by providing the intermediate case body 103 as described above. The front case body 101 and the back case body 102 can be made common for each model.

  Incidentally, the plate-like portion 109 in which the through-hole portion 108 is formed in the intermediate case body 103 is superposed on the element mounting surface 97 of the main control board 91, and is provided upright from the plate-like portion 109 in the intermediate case body 103. The raised part 110 overlapped with the partition wall 107 of the bulging part 105 inside the bulging part 105. Therefore, in the configuration in which the intermediate case body 103 is provided as described above, as shown in FIG. 7A, the element mounting surface 97 of the main control board 91 is the front case body 101 and Covered by the intermediate case body 103.

  As described above, the back case body 102 is fixed to the front case body 101 in which the main control board 91 and the intermediate case body 103 are integrated. As shown in FIG. 8, the back case body 102 is formed in a substantially plate shape having a quadrangular shape, specifically, a rectangular shape when viewed from the front, and includes a planar portion 111 formed in a planar shape and the planar portion. A back side peripheral edge 112 formed so as to surround the periphery of 111 is integrally formed.

  By fixing the back case body 102 from the back side to the front case body 101, the front side peripheral edge 104 of the front case body 101 and the back side peripheral edge 112 of the back case body 102 overlap, and the back surface of the bulging part 105 The open part to the side is closed by the flat part 111 of the back case body 102. In this case, the solder surface of the main control board 91 is covered with the back case body 102. That is, the entire element mounting surface 97 of the main control board 91 is opposed to the front case body 101 and the intermediate case body 103, and the entire solder surface of the main control board 91 is opposed to the back case body 102. . As shown in FIG. 5, the main controller 63 having the above configuration is such that the surface of the front case body 101 faces the back of the pachinko machine 10 and the edge on the side where the intermediate case body 103 is provided is positioned on the upper side. It is installed.

  Next, a configuration related to fixing the front case body 101 and the back case body 102 will be described in detail. The configuration relating to the fixing of both case bodies 101 and 102 includes a restricting means for restricting the mutual displacement between the case bodies 101 and 102 only in a specific restricting direction, and both preventing the misalignment in the restricting direction. Fixing means for fixing the case bodies 101 and 102 to each other.

  First, the regulating means will be described in detail. In the following description of the regulating means, not only FIG. 8 but also FIG. 9 will be referred to as appropriate. FIG. 9A is a plan view showing a part of the main controller 63 in an enlarged manner, and FIG. 9B is a front view showing a part of the main controller 63 in an enlarged manner.

  As shown in FIG. 8, the back case body 102 is integrally formed with a back-side restricting portion 121 as a locking portion as a restricting means. A plurality of back side restricting portions 121 are provided, and these back side restricting portions 121 are formed at equal intervals along each edge at each of the upper edge and the lower edge of the back side peripheral edge portion 112 of the back case body 102. In this case, six back side restricting portions 121 are formed on the top and the bottom, but the number is arbitrary as long as it is plural. Each back side restricting portion 121 is formed to have the same shape, and all are formed to the same size.

  Specifically, as shown in FIG. 9A, the back side restricting portion 121 is formed at the back side peripheral portion 112 of the back case body 102 with the base portion 122 of the back side peripheral portion 112 as the base end. The free end side is formed by being bent at an intermediate position so as to extend toward one side edge of the back case body 102, specifically, toward the right edge. That is, the back-side restricting portion 121 extends from the base portion 122 in the thickness direction of the back case body 102 (the thickness direction of the board box 92) and extends from the standing portion 123 toward the side edge of the back case body 102. The protruding portion 124 is integrally formed. The upright portion 123 and the extending portion 124 are formed with a relatively small thickness dimension (longitudinal dimension).

  The extension part 124 is spaced apart from the base part 122 by the height of the upright part 123, and a locking groove 125 is formed between the extension part 124 and the base part 122. The locking groove 125 is formed along the extended portion 124 and is opened on the free end side of the extended portion 124.

  As shown in FIG. 8, a front side regulation portion 131 is integrally formed with the front case body 101 so as to correspond to the back side regulation portion 121. The front side regulating portion 131 is formed so as to correspond to the back side regulating portion 121 and one body 1 at each of the upper edge and the lower edge of the front side peripheral edge portion 104 of the front case body 101. That is, six front side restricting portions 131 are formed on the upper and lower sides, respectively. However, the specific number is arbitrary as long as it corresponds to the back side regulation unit 121 on a one-to-one basis.

  Specifically, as shown in FIG. 9 (b), the shape of the front side regulating portion 131 includes slits 132 extending along the respective edges at the upper edge and the lower edge of the front side peripheral edge portion 104 of the front case body 101. Is formed. The slit 132 includes an edge wall portion 133 that forms a peripheral surface in the front case body 101, an inner wall portion 134 that is formed to face the edge wall portion 133 in the front case body 101, and these edge wall portions 133. And the periphery is prescribed | regulated by the connection wall part 135 formed so that the inner wall part 134 may be connected, and it has penetrated in the thickness direction (thickness direction of the board | substrate box 92) of the front case body 101. FIG.

  Incidentally, the connecting wall part 135 also has a function of partitioning the adjacent slits 132. Further, the inner wall portion 134 is formed so as to block an intrusion path into the substrate box 92 from the slit 132 side. Furthermore, the inner wall portion 134 is against the series of regulating walls 136 formed inside the back side regulating portion 121 in the back case body 102 when the front case body 101 and the back case body 102 are overlapped. It overlaps outside the regulation wall 136. Thereby, the blocking effect of the intrusion route is enhanced.

  The width dimension of the slit 132, that is, the distance between the edge wall part 133 and the inner wall part 134 is set to be slightly larger than the thickness dimension of the back side regulating part 121. Further, the length dimension of the slit 132, that is, the distance between the opposing connecting wall portions 135 is set to be larger than the length dimension of the extending portion 124.

  As shown in FIG. 9A, each slit 132 is formed with a locking receiving portion 137 that closes the slit 132 on the side of one connecting wall portion 135. The connecting wall portion 135 on the side where the locking receiving portion 137 is formed is a side corresponding to the free end side of the extending portion 124 of the back side regulating portion 121, of both the connecting wall portions 135 in one slit 132. ing.

  The locking receiving portion 137 does not close the entire one slit 132 but only a part thereof. The distance L1 from the connecting wall portion 135 on the side where the latch receiving portion 137 is not formed in one slit 132 to the latch receiving portion 137 is the length in the direction in which the extending portion 124 of the back side regulating portion 121 extends. It is larger than the dimension L2. Thereby, in the structure in which the latch receiving portion 137 is formed as described above, the back side regulating portion 121 can be inserted into the slit 132 from the back side of the front case body 101.

  The locking receiving portion 137 is set to a thickness dimension that can enter the locking groove 125 of the back side regulating portion 121. Further, the latch receiving portion 137 is provided in the slit 132 at an intermediate position in the thickness direction of the front case body 101. Specifically, the latch receiving portion 137 is formed in a position offset in the opening on the back side of the front case body 101 in the slit 132. In this case, in the slit 132, the distance from the opening on the front side of the front case body 101 to the locking receiving portion 137 is the state in which the locking receiving portion 137 enters the locking groove 125 of the back side regulating portion 121. The back side restricting portion 121 does not protrude from the opening.

  When the front case body 101 and the back case body 102 are fixed to each other, the back side regulating portion 121 is first inserted into the slit 132 from the back side of the front case body 101. By inserting the back side restricting portion 121 into the slit 132, the back side restricting portion 121 is disposed between the edge wall portion 133 and the inner side wall portion 134 in the front case body 101, and the back side restricting portion 121 is formed by these wall portions 133, 133. The movement of the front case body 101 and the back case body 102 in the direction in contact with 134, that is, the movement in the vertical direction is restricted.

  As described above, in a state where the back side regulating portion 121 is inserted into the slit 132, the free end of the extending portion 124 of the back side regulating portion 121 faces the locking receiving portion 137 side in the inserted slit 132. Further, in this state, the front case body 101 and the back case body 102 are not completely overlapped but are shifted in the left-right direction.

  Thereafter, at least one of the front case body 101 or the back case body 102 is slid in a direction in which the case bodies 101 and 102 completely overlap each other, whereby the front side regulation portion 131 is inserted into the locking groove 125 of the back side regulation portion 121. The latch receiving part 137 enters. In this state, the movement direction of the front case body 101 and the back case body 102 is regulated so that the movement can be performed only in the direction in which the locking receiving portion 137 is removed from the locking groove 125. Then, by fixing with the fixing means in this state, it becomes impossible to move in the movement direction regulated by the regulating means, and the front case body 101 and the back case body 102 are fixed to each other.

  Next, the fixing means will be described.

  As shown in FIG. 8, a front side fixing region 141 is integrally formed on one side edge of the front side peripheral edge 104 of the front case body 101. The position where the front side fixing region 141 is provided is the front end side when the front case body 101 is moved in the direction restricted by the restriction means. The front side fixing region 141 is formed to extend laterally from a space defining wall 145 that defines the internal space of the substrate box 92 at the front side peripheral edge 104, and has a substantially plate shape.

  Corresponding to the front side fixing region 141, a back side fixing region 142 is integrally formed on the back side peripheral edge 112 of the back case body 102. The back-side fixing region 142 extends laterally from the flat portion 111 and has a substantially plate shape, like the front-side fixing region 141. In a state where the front case body 101 and the back case body 102 are overlapped so that the locking receiving portion 137 of the front side regulating portion 131 enters the locking groove 125 of the back side regulating portion 121, the front side fixing region 141 and the back side The fixed region 142 overlaps.

The front side fixing region 141 is integrally formed with one front side coupling portion 143 at each of the upper end and the lower end thereof. Each front-side coupling portion 143 has a prismatic shape and protrudes from the plate-like base 144 in the front-side fixing region 141. In this case, each front side coupling portion 143 faces the space defining wall 145 in the front case body 101, and a gap is formed between them.
Each front side coupling portion 143 is coupled to the plate-like base 144 via a plurality of coupling portions 146. The connecting portion 146 is set to have a smaller width dimension than the front side connecting portion 143 so that the connecting portion 146 can be easily cut by a tool such as a nipper or a cutter. Each front-side coupling portion 143 is formed with a through hole 147 that penetrates the front-side coupling portion 143 in the front-rear direction.

  The back side fixing portion 142 is integrally formed with one back side connecting portion 148 at each of the upper end and the lower end thereof in a one-to-one correspondence with the front side connecting portion 143. Each back side coupling portion 148 is formed to protrude rearward with respect to the plate-like base 149 in the back side fixing region 142, and has a boss shape. Each back side coupling portion 148 is formed with a screw hole 150 extending in the axial direction of the boss. The screw hole 150 communicates with the through hole 147 formed in the front side coupling portion 143 so as to be on the same axis. A break screw 151 is screwed into the through hole 147 and the screw hole 150 that communicate with each other from the through hole 147 side.

  Here, the breaking screw 151 is one in which the strength of the connecting portion between the head 151a into which the tip of a tool such as a driver can be inserted and the side on which the screw groove is formed is set low, and is tightened further. When a predetermined force is further applied to the head 151a by the tool at a position where it cannot be performed, the connecting portion is cut and the head 151a is separated. That is, the breaking screw 151 cannot be rotated in the loosening direction using the tool after screwing. If it is possible to prevent loosening of the coupling between the front side coupling portion 143 and the back side coupling portion 148 after screwing, the fixture (coupling means) that couples the coupling portions 143 and 148 is broken. It is not limited to the screw 151 and may be a well-known one-way screw.

  A plurality of combinations of the front side coupling portion 143 and the back side coupling portion 148 are provided as described above, and all the combinations are coupled by the break screw 151. In other words, the combination of the upper front side coupling portion 143 and the back side coupling portion 148 is coupled by the breaking screw 151, and the breaking screw 151 is coupled to the combination of the lower front side coupling portion 143 and the back side coupling portion 148. The combination by is done. And all the breaking screws 151 have the head 151a removed.

  As described above, the front case body 101 and the back case body 102 are fixed to each other in a state in which the front case body 101 and the back case body 102 are not separable by being connected to each other. In this case, the locking receiving portion 137 enters the locking groove 125 as described above, and the combination of the locking groove 125 and the locking receiving portion 137 extends along the upper edge of the substrate box 92. Since there are a plurality and a plurality along the lower edge, the front case body 101 and the back case body 102 are stacked in the thickness direction of the substrate box 92 (that is, the front case body 101 and the back case body 102 are overlapped). Even if it is attempted to be separated in the alignment direction), it is firmly regulated. Therefore, even if the boundary portion between the front case body 101 and the back case body 102 is forcibly opened and an attempt is made to insert a fraudulent jig into the main control board 91 from there, it becomes difficult. In particular, since the locking range between the locking groove 125 and the locking receiving portion 137 is widely secured as will be described later, the effect of suppressing the fraud is enhanced.

  A return portion that overlaps the front side peripheral edge 104 of the front case body 101 from the front side of the main controller 63 is integrally formed on the left edge of the back side peripheral edge 112 of the back case body 102. Also by the returning portion, even if the front case body 101 and the back case body 102 are separated in the thickness direction of the substrate box 92, it is firmly regulated.

  In order to release the fixed state, it is necessary to destroy the front-side fixed region 141 and the back-side fixed region 142, and if it is destroyed, the trace remains. That is, the front-side coupling portion 143, the back-side coupling portion 148, and the breaking screw 151 constitute a caulking structure as a fixing means, and after the coupling by the caulking structure, the front case body 101 and the back case body 102 are separated. At that time, the trace, that is, the opening history of the substrate box 92 remains.

  On the other hand, as described above, the front side connecting portion 143 is connected to the plate-like base 144 via the connecting portion 146, and the connecting portion 146 is easier to cut with a tool such as a nipper or a cutter than the front side connecting portion 143. The width dimension is set small so that it can be performed. Therefore, when the board box 92 is opened to inspect the main control board 91 in a game hall or the like, the connecting portion 146 is cut so that the front side connecting portion 143 is separated from the front case body 101, and the caulking It becomes possible to cancel the separation prevention state by the structure.

  However, in the configuration in which the fragile connecting portion 146 is provided as described above, it is assumed that the substrate box 92 is illegally opened so that the cutting of the connecting portion 146 is not as conspicuous as possible. In this case, it is assumed that although the caulking structure is provided, it is not possible to find that the connecting portion 146 is cut, and the above fraud is overlooked. On the other hand, in this pachinko machine 10, in order to completely separate the front case body 101 and the back case body 102 and expose the main control board 91, the front case body 101 or the back surface is cut after the connecting portion 146 is cut. The case body 102 is configured to require further destruction.

  Therefore, the configuration that requires further destruction will be described below.

  Even when the connecting portion 146 is cut and the front side connecting portion 143 is separated from the front case body 101, the state where the front side connecting portion 143 is connected to the back side connecting portion 148 is maintained. The coupling portion 143 faces the space defining wall 145 in the front case body 101. On the other hand, the restriction means is provided as described above, and when the front case body 101 and the back case body 102 are separated, it is necessary to slide both of them in the left-right direction. Specifically, when the case body 101 is moved when the case bodies 101 and 102 are separated, it is necessary to move the table case body 101 so that the front-side fixing region 141 is at the head.

  In this case, as shown in FIG. 9A, the distance L3 between the front side coupling portion 143 and the space defining wall 145 is set so that the locking receiving portion 137 of the front side regulating portion 131 locks the back side regulating portion 121. The length is set to be shorter than the length L4 entering the groove 125. That is, before the regulation of the separation direction by the regulating means is released, the space defining wall 145 contacts the front side coupling portion 143 and further movement is regulated. Further, in this state, the mutual positions of the front case body 101 and the back case body 102 are slightly shifted in the left-right direction from the initial position, and the main control board 91 is not exposed. Therefore, in order to completely separate the front case body 101 and the back case body 102 and expose the main control board 91, the back side restricting portion 121 and the front side restricting portion 131 constituting the restricting means, the front side connecting portion 143, and the like are provided. Further destruction is required. Accordingly, in order to completely separate the front case body 101 and the back case body 102 and expose the main control board 91, further destruction of the front case body 101 or the back case body 102 is required after the connecting portion 146 is cut. As a result, the effect of preventing unauthorized opening of the substrate box 92 is enhanced.

  Here, in the configuration in which the entire solder surface of the main control board 91 faces the back case body 102 in a state where the board box 92 is not opened as described above, the restriction direction by the restriction means is the same as that of the back case body 102. The distance between the main control board 91 and the solder surface is not changed. As a result, the act of breaking the connecting portion 146 and slightly separating the front case body 101 and the back case body 102 and attempting to cheat on the main control board 91 in this separated state. It is possible to make it difficult to perform.

  In addition, when the connecting portion 146 is broken to separate the front case body 101 and the back case body 102 from each other, and the front case body 101 is in contact with the front side coupling portion 143, the entire solder surface of the main control board 91 is It still faces the back case body 102. Also from this point, for the act of breaking the connecting portion 146 and slightly separating the front case body 101 and the back case body 102 and attempting to cheat on the main control board 91 in this separated state, It becomes possible to make it difficult to perform the act.

  Next, in the configuration that requires further destruction as described above, the destruction-accepting structure provided in the restricting means to make it relatively easy to separate the front case body 101 and the back case body 102 when the main control board 91 is inspected. The configuration will be described below with reference to FIGS. FIG. 10 is an explanatory diagram for explaining a breakable structure. Note that, although this breakable structure is provided for each combination of the back side restricting portion 121 and the front side restricting portion 131, all the configurations are the same, so in the following description, only one combination will be described. .

  As described above, the restricting means is composed of the back side restricting portion 121 and the front side restricting portion 131, and when the locking receiving portion 137 of the front side restricting portion 131 enters the locking groove 125 of the back side restricting portion 121, The above regulations are in effect. Further, in the front side regulating portion 131, the latch receiving portion 137 enters the slit 132 defined by the edge wall portion 133, the inner wall portion 134, and the adjacent connecting wall portion 135, and the latching groove 125. The periphery of the locking portion between the locking receiving portion 137 and the locking receiving portion 137 is surrounded by the wall portions 133 to 135.

  In this configuration, as shown in FIG. 9B, the edge wall portion 133 protrudes outward so that the inner wall surface is separated from the back-side regulating portion 121 over a predetermined range in the direction in which the slit 132 extends. An overhang region 155 is formed. Further, as shown in FIGS. 9A and 10A, on the both ends in the extending direction of the slit 132 in the overhanging region 155, there are nippers, cutters, etc. as compared with other portions in the overhanging region 155. A fragile portion 156 having a small width dimension is formed so that the tool can be easily cut. By cutting the two weak portions 156 using a tool and removing the region between the two weak portions 156 in the overhang region 155, the inside of the slit 132 is exposed on the peripheral surface (specifically, the upper surface or the lower surface) of the substrate box 92. To do.

  However, the position where the region between the fragile portions 156 is formed in the overhang region 155 is a region that does not overlap with the locking receiving portion 137, and the fragile portion 156 is cut to remove the region between the two fragile portions 156. Even if it does, the latching receiving part 137 is not exposed, and only the back side regulation part 121 is exposed. In other words, the locking portion between the locking groove 125 and the locking receiving portion 137 is not exposed. Therefore, in this state, the locked state between the locking groove 125 and the locking receiving portion 137 cannot be released.

  When the region between the two weak portions 156 is removed in the overhang region 155, the locking groove 125 is exposed, but the exposed range is narrow. On the other hand, as shown in FIG. 10B, until the position where the space defining wall 145 of the front case body 101 hits the front side coupling portion 143 remaining in the state coupled with the back side coupling portion 148 as a trace portion. By sliding at least one of the front case body 101 or the back case body 102, the range exposed in the locking groove 125 can be widened.

  By exposing the locking groove 125 as described above, the extended portion 124 of the back side regulating portion 121 is cut by a tool such as a nipper on the upright portion 123 side from the locking portion with the locking receiving portion 137. It becomes possible. Then, by cutting the extension portion 124 as shown in FIG. 10C, the locked state between the back side regulating portion 121 and the front side regulating portion 131 is released, and as shown in FIG. The case body 101 and the back case body 102 can be separated.

  In the configuration in which the restriction means is released by destroying the extending portion 124 as described above, there is a problem even if a wide locking region between the locking groove 125 and the locking receiving portion 137 is secured. Does not occur.

  Next, the overall flow when the substrate box 92 is opened will be described with reference to FIG. FIG. 11 is an explanatory diagram for explaining the overall flow when the substrate box 92 is opened.

  When the substrate box 92 is opened, the connecting portion 146 in the caulking structure is first cut as shown in FIG. Accordingly, as shown in FIG. 11B, at least one of the front case body 101 and the back case body 102 can be slid in the left-right direction.

  Thereafter, as shown in FIG. 11C, the fragile portions 156 are cut with respect to all the overhang regions 155 of the edge wall portion 133, and the regions between the fragile portions 156 are removed. Thereafter, as shown in FIG. 11 (d), the extending portions 124 are cut for all the back side restricting portions 121. As a result, the restriction by the restricting means is released, and the front case body 101 and the back case body 102 are completely connected even if the front side joint portion 143 remains in a state of being coupled to the back side joint portion 148 as a trace portion. Can be separated. Therefore, the opening operation of the substrate box 92 during the inspection of the main control substrate 91 can be performed relatively easily.

  In the configuration in which the cutting of the edge wall portion 133 and the extending portion 124 can be performed relatively easily as described above, the cutting of the edge wall portion 133 and the extending portion 124 can be performed relatively easily even during an illegal act. However, at the time of cutting, it is necessary to remove at least the edge wall portion 133 over a predetermined range. In other words, the connecting portion 146 having a caulking structure only needs to be cut when releasing the separation prevention by the caulking structure, and does not need to be removed over a predetermined range. Therefore, even if the connecting portion 146 is disconnected in the case of fraud, it is difficult to detect after that. On the other hand, in order to expose the inside of the slit 132, it is necessary to remove the edge wall portion 133 over a predetermined range, so that the trace is conspicuous and the substrate box 92 is illegally opened. It becomes easy to discover it. Further, since the edge wall portion 133 and the extension portion 124 are cut at a plurality of locations as described above, it is easy to find out if the substrate box 92 is illegally opened accordingly.

  Furthermore, the caulking structure connecting portion 146 and the edge wall portion 133 of the restricting means are provided on the front case body 101, and the extending portion 124 of the back side restricting portion 121 is provided on the back case body 102. That is, when the substrate box 92 is opened by the above procedure, it is necessary to destroy both the front case body 101 and the back case body 102.

  Next, another fixing structure provided in the substrate box 92 will be described.

  As shown in FIG. 8, sticking plate portions 161 and 162 are formed in the middle portion of the front side fixing region 141 and the middle portion of the back side fixing region 142, respectively, and these sticking plate portions 161 and 162 overlap each other. A plurality of sets of screw holes communicating with each other are formed in both the pasting plate portions 161 and 162, and screws 163 are screwed into these screw holes. As the screw 163, a well-known removable screw is used. Since the screws 163 are screwed as described above, both the pasting plate portions 161 and 162 are fixed. Then, as shown in FIGS. 7A and 7B, a sealing seal 164 is pasted on the pasting plate portions 161 and 162 so as to straddle the boundary between the both. When the seal seal 164 is peeled off after being stuck, the pressure-sensitive adhesive layer remains on the sticking plate portions 161 and 162 and cannot be attached again.

  Further, a temporary fixing coupling portion 171 is formed between the front side coupling portion 143 and the sticking plate portion 161 in the front side fixing region 141, and the temporary fixing coupling portion is also formed in the back side fixing region 142 corresponding thereto. 172 is formed. These temporary fixing coupling portions 171 and 172 are formed with screw holes that communicate with each other, and the front-side fixing region 141 and the back-side fixing region 142 are fixed by screwing screws into the communicating screw holes. Can do. In this temporary fixing, the main control board 91 is accommodated in the board box 92 in which the fixing means and the regulating means are destroyed until the new board box 92 is obtained from the manufacturer after the inspection of the main control board 91 in the game hall. This is done when the function is performed.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 12, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The main control board 91 provided in the main controller 63 incorporates a main control circuit 202 and a power failure monitoring circuit 203. A CPU chip 93 is mounted on the main control circuit 202. The CPU chip 93 temporarily stores various control programs executed by the CPU chip 93 and ROM 205 storing fixed value data, and various data when the control program stored in the ROM 205 is executed. And a RAM 206 as a memory for the memory, and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit.

  The CPU chip 93 is provided with an input port and an output port. Connected to the input side of the CPU chip 93 are a power failure monitoring circuit 203 provided on the main control board 91, a payout control board 211 provided on the payout control device 82, and a switch group (not shown). In this case, the power failure monitoring circuit 203 is connected to a power source and launch control board 215 provided in the power source and launch control device 83, and power is supplied to the CPU chip 93 via the power failure monitoring circuit 203.

  On the other hand, a power failure monitoring circuit 203, a payout control board 211 and a relay terminal board 219 are connected to the output side of the CPU chip 93. Various commands such as a prize ball command are output to the payout control board 211. Various commands are output from the main control circuit 202 to the sound lamp control board 221 provided in the sound lamp control device 66 via the relay terminal board 219.

  The power failure monitoring circuit 203 relays between the main control circuit 202 and the power source and launch control board 215, and monitors a DC stable voltage of 24 volts that is the maximum voltage output from the power source and launch control board 215.

  The payout control board 211 performs payout control of prize balls and rental balls by the payout device 78. The CPU 212 that is an arithmetic unit includes a ROM 213 that stores a control program executed by the CPU 212, fixed value data, and the like, and a RAM 214 that is used as a work memory or the like.

  The CPU 212 of the payout control board 211 is provided with an input / output port. A main control circuit 202, a power and launch control board 215, and a back pack board 79 are connected to the input side of the CPU 212. The main control circuit 202 and the back pack substrate 79 are connected to the output side of the CPU 212.

  The power source and launch control board 215 includes a power source unit 216 and a launch control unit 217. The power supply unit 216 is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 202, the payout control board 211, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 202 and the payout control board 211 through the path. The launch control unit 217 is responsible for launch control of the game ball launch mechanism 50, and the game ball launch mechanism 50 is driven when predetermined launch conditions are met.

  The sound lamp control board 221 controls the display control device 225. The CPU 222 that is an arithmetic unit includes a ROM 223 that stores a control program executed by the CPU 222, fixed value data, and the like, and a RAM 224 that is used as a work memory or the like.

  The CPU 222 of the sound lamp control board 221 is provided with an input / output port. A main control circuit 202 is connected to the input side of the CPU 222 through a relay terminal board 219 and controls the display control device 225 based on various commands output from the main control circuit 202. The display control device 225 controls the symbol display device 41 based on a display command input from the sound lamp control board 221.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In the board box 92 of the main control device 63, the front case body 101 and the back case body 102 are prevented from being separated by fixing the front side coupling portion 143 and the back side coupling portion 148 with the breaking screw 151. As a result, it is possible to suppress the act of improperly opening the board box 92 and impersonating the main control board 91. Further, a connecting portion 146 that is easier to break than the front side connecting portion 143 is provided, and the state in which the front case body 101 and the back case body 102 are fixed by releasing the connecting portion 146 is released. Release of fixation by the fixing means can be performed relatively easily. Therefore, in the inspection of the main control board 91 in the game hall, the workability of the release work when releasing the fixation by the fixing means is improved.

  In the above configuration, by providing the regulating means including the back side regulating unit 121 and the front side regulating unit 131, the direction when the front case body 101 and the back case body 102 are separated from each other is regulated in the regulating direction. Yes. And when the connection part 146 is destroyed and both case bodies 101 and 102 are separated in the direction regulated by the regulating means, in a state fixed to the back side coupling part 148 before the regulation is released. The front case body 101 comes into contact with the remaining front side coupling portion 143, and further movement is restricted. Thereby, even if the connection part 146 is destroyed, both the case bodies 101 and 102 cannot be completely separated, and further destruction of the case bodies 101 and 102 is required. Therefore, the act of separating the two case bodies 101 and 102 from each other becomes complicated for the fraudulent person, and the act of illegally opening the board box 92 can be suppressed.

  Further, even if the substrate box 92 is illegally opened, at that time, not only the connecting portion 146 but also a portion destroyed in the substrate box 92 exists. Therefore, even if the board box 92 is illegally opened, the fact can be easily found.

  As described above, when the case bodies 101 and 102 are separated in the direction regulated by the regulating means, the portion that contacts the front case body 101 remains in the state of being fixed to the back side coupling portion 148 and the front side coupling portion 143. It has become. As a result, the function of preventing the separation of the two case bodies 101 and 102 is performed by the front side coupling portion 143 even after the connection portion 146 is broken. Therefore, a configuration other than the front side coupling portion 143 and the back side coupling portion 148 is separately provided. As compared with the above, the above-described excellent effect can be obtained while simplifying the configuration. Further, the front case body 101 and the back case body 102 have a function of fixing the front case body 101 and the back case body 102, and the case body 101 and 102 are prevented from being separated in the situation where the connecting portion 146 is broken. Therefore, the above-described excellent effect can be obtained without complicating the fixing work of the case bodies 101 and 102.

  By destroying the restricting means, it is possible to separate both case bodies 101 and 102 in a direction in which the front case body 101 does not come into contact with the front side coupling part 143 remaining in a state fixed to the back side coupling part 148. . As a result, when the main control board 91 is inspected at the game arcade, the portions to be destroyed other than the connecting portion 146 are collected in the restricting means. Therefore, when separating both case bodies 101 and 102, it is not necessary to destroy other places by destroying the connecting portion 146 and the restricting means, so the workability of the inspection is not reduced as much as possible. Can be. Moreover, in the said structure, when the fraud which opens the board | substrate box 92 is performed, it is thought that destruction with the connection part 146 and a control means is performed easily. Therefore, the place to be confirmed when the substrate box 92 is illegally opened becomes clear, so that the workability of the confirmation work is improved and it is easy to find out if the unauthorized opening has been performed.

  In the configuration in which the case when the case bodies 101 and 102 are separated from each other by the locking groove 125 of the back side regulating portion 121 and the latch receiving portion 137 of the front side regulating portion 131 is regulated in the regulating direction, these locking An edge wall 133, an inner wall 134, and a connecting wall 135 are provided as an enclosing portion that surrounds the locking portion of the groove 125 and the locking receiving portion 137. This makes it difficult to unlock the locking groove 125 and the locking receiving portion 137, that is, to release the restriction of the restriction means, and for the fraudulent person, the restriction release operation of the restriction means becomes complicated. In addition, when the restriction release operation is performed, the enclosure portion is destroyed, and at least one of the back side restriction portion 121 and the latch receiving portion 137 exposed at the broken position is broken, the operation becomes complicated. This also makes it possible to suppress the cheating. Furthermore, when the restriction release operation is performed in this way, the destruction portion covers a relatively wide range, so that discovery can be facilitated when the board box 92 is illegally opened.

  By destroying the edge wall portion 133 that constitutes the peripheral surface of the substrate box 92 among the wall portions 133 to 135 that constitute the surrounding portion, the engagement portions of the engagement groove 125 and the engagement receiving portion 137 are changed. The inside of the accommodated slit 132 will be exposed. And the regulation of a regulation means is cancelled | released by destroying the back side regulation part 121 in this state. That is, the restriction release operation of the restriction means can be performed at the peripheral edge of the substrate box 92. Therefore, compared with the configuration in which the above operation needs to be performed on the center side of the substrate box 92, the restriction release operation of the restriction means can be easily performed. Therefore, the workability of the work of opening the board box 92 when the main control board 91 is inspected in the game hall can be improved.

  Further, the edge wall portion 133 is formed with an overhanging region 155 that projects outward, and the overhanging region 155 has a weakened portion that is formed more fragile than other portions of the edge wall portion 133. 156 is formed. As a result, the workability when the edge wall 133 is destroyed to expose the inside of the slit 132 can be improved, and accordingly, the board box 92 of the board box 92 when the main control board 91 is inspected in the game hall can be improved. The workability of the opening work can be improved. In addition, in a state where the inside of the slit 132 is exposed, the width of the locking groove 125 exposed by moving the front case body 101 to a position where it abuts on the front side coupling portion 143 can be increased. Therefore, it becomes easy to destroy the extension part 124 of the back side regulation part 121, and it becomes easy to cancel the regulation by the regulation means. Also from this point, the workability of the work of opening the board box 92 when the main control board 91 is inspected in the game hall can be improved.

  In the configuration in which the overhang region 155 and the fragile portion 156 are formed as described above, when the fragile portion 156 is cut and the overhang region 155 is removed, the back side regulating portion 121 is exposed, and the latch receiving portion 137 is not exposed. In this case, the overhang region 155 and the fragile portion 156 are provided in the front case body 101, and the back side regulating portion 121 is provided in the back case body 102. That is, when the restriction by the restriction means is released based on cutting the fragile portion 156 and removing the overhang region 155, it is necessary to destroy both the front case body 101 and the back case body 102.

  Here, as an illegal act against the main control device 63, two main control devices 63 are prepared, taken out from one main control device 63 without destroying the front case body 101, and from the other main control device 63. It is assumed that the back case body 102 is taken out without destroying it. In this case, a genuine board box 92 can be obtained by combining the front case body 101 and the back case body 102 taken out without being destroyed. Then, when the main control device 63 of the pachinko machine 10 is replaced with the main control device 63 configured by accommodating the illegal main control board 91 in the illegally obtained board box 92, the discovery is performed. It becomes difficult. When such an illegal act is assumed, in the configuration in which the overhang area 155 and the fragile portion 156 are provided as described above, there is a concern that the illegal act may be easily performed. On the other hand, when the restriction by the restriction means is released based on cutting the fragile portion 156 and removing the overhang region 155 as described above, it is necessary to destroy both the front case body 101 and the back case body 102. As a result, it is possible to make it difficult to perform the above fraud.

  In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows. Incidentally, the configurations of the following different modes may be applied individually to the configurations of the above embodiments, or may be applied in combination with each other.

  (1) The configuration of the main controller may be changed to the configuration shown in FIG.

  The main controller 230 shown in FIG. 13A includes a board box 231, and the board box 231 includes a front case body 232 and a back case body 233. In this case, the front case body 232 is supported so as to be rotatable with respect to the back case body 233 at one end side thereof. In addition, a front side coupling portion 234 is formed on the rotation tip side of the front case body 232, and the front side coupling portion 234 is in a state where the front case body 232 is closed on the rotation tip side of the back case body 233. A back side coupling portion 235 is formed at the overlapping position. Of these coupling portions 234 and 235, the front side coupling portion 234 is coupled to the base portion 236 of the front case body 232 via the coupling portion 237, and the coupling portion 237 is connected to the front side coupling portion 234 and the front case body. It is formed weaker than the base portion 236 of 232. Then, the front case body 232 and the back case body 233 are coupled in a state where they cannot be separated by fixing the front side coupling part 234 and the back side coupling part 235 with a fixture such as a breaking screw 238 that cannot be fixed. By breaking the connecting portion 237, the coupling between the front case body 232 and the back case body 233 is released.

  In the above configuration, when the front case body 232 is rotated while the front side coupling portion 234 is fixed to the back side coupling portion 235, the passage path through which the rotation tip of the base portion 236 of the front case body 232 passes. Is placed on top. Therefore, as shown in FIG. 13B, even if the connecting portion 237 is broken and the front case body 232 is rotated with respect to the back case body 233, the rotating front end portion of the base portion 236 remains as a trace portion. The front case body 232 cannot be completely opened by hitting the front side coupling portion 234. Then, in order to completely open the front case body 232, it is necessary to destroy the shaft portion and the like. Thereby, it becomes possible to suppress the act of opening the substrate box 231 illegally.

  (2) In the above embodiment, the direction in which the front case body 101 and the back case body 102 are separated is regulated in the longitudinal direction of the substrate box 92 by the regulating means, but the present invention is not limited to this. You may restrict | limit to the transversal direction of 92. In this case, the front side coupling portion 143 may be disposed at a position where a part of the front case body 101 passes in a situation where the direction of separation in the short direction is regulated by the regulating means. Further, the direction in the case of separating may be configured to be regulated in the thickness direction of the substrate box 92 by the regulating means. In this case, the front side coupling portion 143 may be arranged at a position where a part of the front case body 101 passes in a situation where the direction of separation in the thickness direction is regulated by the regulating means.

  (3) The configuration of the main controller may be changed to the configuration shown in FIG.

  In the board box 242 of the main controller 241 shown in FIG. 14, the front case body 243 is slid relative to the back case body 244 in a situation where the position of the fixing means forming the caulking structure is regulated by the regulating means. It is not in the beginning but in the middle of the slide movement direction. Therefore, even if the front side coupling portion 245 and the base portion 246 of the front case body 243 are coupled and the coupling portion 247 formed weaker than the front side coupling portion 245 is cut, the front side coupling portion 245 is not attached to the front case body. Since it is on the movement path when 243 is slid in the direction regulated by the regulating means, the regulating means etc. is destroyed to separate the front case body 243 and the back case body 244 and expose the main control board. Need arises. Thereby, it becomes possible to suppress the act of opening the substrate box 242 illegally.

  (4) The connecting portion 146 formed weaker than the corresponding connecting portion may be provided for the back side connecting portion 148 instead of being provided for the front side connecting portion 143. Then, by cutting the connecting portion 146, the back side coupling portion 148 is separated from the back case body 102 and remains in a state of being fixed to the front side coupling portion 143. In this case, when the front case body 101 and the back case body 102 are separated from each other, not only the connecting portion 146 but also other parts such as the restriction means are destroyed by making the restriction direction by the restriction means opposite to that of the above embodiment. Will be required.

  (5) In the above-described embodiment, the back side regulating portion 121 may be provided in the front case body 101 instead of the back case body 102, and the front side regulating portion 131 may be provided in the back case body 102 instead of the front case body 101.

It is good also as a structure which provides a body.

  (6) In the above embodiment, when the front case body 101 is slid in the direction restricted by the restricting means, the position of the front side coupling portion 143 comes into contact with the space defining wall 145 and further slide movement is performed. Although the restriction position is set, the front side coupling portion 143 may be disposed at a position where the coupling portion 146 is in contact with the space defining wall 145 in an initial state where the connection portion 146 is not broken. In this case, even if the connecting portion 146 is broken and the front case body 101 and the back case body 102 are moved in the direction of separating, the front side coupling portion 143 remaining in the state of being fixed to the back side coupling portion 148 is already in the space. Since it is in contact with the regulation wall 145, it cannot be moved.

  (7) You may provide the weak part formed weaker than the other site | part of the said extension part 124 with respect to the extension part 124 of the back side control part 121. FIG. However, the position where the fragile portion is formed is a position that can be exposed after removing the overhanging region 155 of the front side regulating portion 131, and further, the locking groove 125 and the locking receiving portion are cut by cutting the fragile portion. It is good to set it as the position where the locked state with 137 is released. According to this configuration, the opening operation of the substrate box 92 during maintenance of the main control substrate 91 can be performed more easily than in the above embodiment.

  (8) In the above embodiment, the substrate box 92 of the main controller 63 may be configured not to include the intermediate case body 103, and the front case body 101 may be configured not to include the long hole portion 106. In this case, the substrate box 92 is formed from a pair of case bodies 101 and 102. Further, the board box 92 may be formed by combining four or more case bodies instead of the three case bodies.

  (9) As a fixture for fixing the front side coupling portion 143 and the back side coupling portion 148, a hook metal fitting may be used in place of the breaking screw 151. In this case, after fixing both the coupling parts 143 and 148 with the hooking tool, the hooking metal fitting cannot be removed, so that the coupling part 146 and the like are broken when the coupling parts 143 and 148 are unfixed. Can be required.

  Moreover, as a structure which fixes the front side coupling | bond part 143 and the back side coupling | bond part 148, it is good also as a structure which replaces with the structure using a fixing tool as mentioned above, and fixes both coupling | bond part 143,148 using an adhesive agent, It is good also as a structure which adhere | attaches and integrates both the joint parts 143 and 148 using an ultrasonic wave or a heat | fever. In these cases, the strength of the connecting portion 146 may be lower than the adhesive strength by the adhesive or the strength of fixing.

  (10) The configuration for forming the connecting portion 146 and the fragile portion 156 in a fragile manner is not limited to the configuration in which the connecting portion 146 and the fragile portion 156 are formed to be thin or narrow. It is good also as a structure formed with material with low intensity | strength compared with the circumference | surroundings, and it is good also as a structure in which the connection part 146 and the weak part 156 have a cavity.

  (11) In the above-described embodiment, only a part of the combination of the back side restricting portion 121 and the front side restricting portion 131 provided in a plurality of sets (specifically, six) is separated when the case bodies 101 and 102 are separated. A configuration requiring destruction may be applied. In this case, the workability of the work of opening the board box 92 can be improved during the inspection of the main control board 91 at the game hall.

  (12) In the above embodiment, when the pair of weakened portions 156 is cut and the overhanging region 155 between the weakening portions 156 is removed, the overhanging region 155 is separated from the original position, but the front case body It may be configured to remain on the front case body 101 side by being partially connected to 101.

  (13) In the above-described embodiment, among the four sides of the substrate box 92, the restricting means is provided on each of the opposing sides, and the fixing means is provided on the predetermined side where the restricting means is not provided. This may be changed. For example, a regulating unit may be provided on each of the opposing sides, and a fixing unit may be provided on each of the other opposing sides.

  Specifically, the configuration may be provided on the left edge of the substrate box 92 in a state where the configuration of the fixing means provided on the right edge of the substrate box 92 in the above embodiment is reversed. That is, the back side coupling portion 148 in the above embodiment is provided above and below the left edge of the front case body 101, and the front side coupling portion 143 in the above embodiment is provided above and below the left edge of the back case body 102. And the connection part 146 in the said embodiment is arranged in parallel with this front side coupling | bond part 143. FIG. According to this configuration, since the front case body 101 and the back case body 102 are fixed by the fixing means at the four corners of the substrate box 92, the case bodies 101 and 102 can be more firmly fixed. Further, when each connecting portion 146 is cut and both case bodies 101 and 102 are to be separated, the front case body 101 abuts on the right side trace portion and the back case body 102 abuts on the left side trace portion. It will be. Therefore, it is possible to more reliably prevent the separation of the case bodies 101 and 102 due to the contact between the trace portion and the case body.

  (14) The configuration applied to the board box 92 of the main control device 63 in the above embodiment is applied to other control devices such as the sound lamp control device 66, the payout control device 82, the power source and the launch control device 83. Also good.

  (15) In each of the above embodiments, the present invention is applied to the pachinko machine 10 provided with the upper plate 57a and the lower plate 58a as the outer storage unit, but instead, a single outer storage unit is provided.
