  As a kind of gaming machine, a pachinko gaming machine, a slot machine, and the like are known. These gaming machines include a control board on which an element such as a ROM on which a CPU is mounted and a control program related to the game is stored is mounted, and a series of games are controlled by the control board. . In recent years, there are CPUs and ROMs that are made into one chip and mounted on a control board.

In this type of gaming machine, for example , in order to obtain illegal profits, for example, an element in which a control program in a control board is stored (if the CPU or ROM is integrated into one chip, the chip) is exchanged. the contents are cheating are reported with respect to the control board, such as to change, fraud of conventional than various have been studied.

  For example, there is known one having a coupling structure (so-called caulking structure) for coupling a plurality of box constituting bodies constituting a substrate box to each other (see, for example, Patent Document 1). The coupling structure is configured to require destruction when the coupling is released. Thereby, when the substrate box is opened, an opening history due to the destruction can be left, and when the substrate box is illegally opened, it can be found.

On the other hand, in a game arcade, the control board may be inspected by an external engine or the like. Therefore, in order to facilitate the opening operation of the substrate box at the time of this inspection, the joint structure is positively provided with a fragile portion, and the fragile portion is broken (cut or the like) so as to depend on the joint structure. coupling is released, there is that is to allow the opening of the substrate box.

According to the present invention, while making it possible to satisfactorily perform the work of opening the board box in the game hall, it is possible to suitably suppress fraud against the element in which the control program is stored, or when the fraud is performed. It becomes possible to discover suitably.

First, the invention that can be extracted from the present embodiment will be described while showing effects and the like as necessary.

  The following means are as follows: “As a kind of gaming machine, a pachinko gaming machine, a slot machine, etc. are known. These gaming machines are equipped with a CPU and a ROM in which a control program related to the game is stored. A series of games are controlled by the control board mounted on the control board.In recent years, CPUs and ROMs are integrated into one chip and mounted on the control board. In this type of gaming machine, for the purpose of obtaining illegal profits, an element (control chip in the case where the CPU or ROM is integrated into one chip) is exchanged in the control board. Many fraudulent acts against the control board have been reported, such as changing game contents, etc., and various fraud countermeasures have been studied. A structure having a coupling structure (so-called caulking structure) for coupling a plurality of box structures to each other is known (see, for example, Japanese Patent Application Laid-Open No. 2003-180917). It is configured to require destruction when the bond is released, so that when the board box is opened, an opening history due to the breaking can be left, and if the board box is opened illegally, it can be detected. On the other hand, the control board may be inspected by an external engine, etc. in the amusement hall.Therefore, in order to facilitate the opening work of the board box at the time of this inspection, the coupling structure has a fragile part. Is actively provided, and by breaking (cutting, etc.) the fragile part, the connection by the connection structure is released and the board box can be opened. However, even in the case of a control board device having the above-mentioned coupling structure, it is considered that fraudulent acts are still performed, for example, it is possible to perform the destruction of the fragile part inconspicuously, and then the board There is a risk that it will not be easy to detect that the box has been opened illegally, especially if the element in which the control program is stored is illegally replaced. It is made in order to solve the technical background and problems.

Means 1. A control board (main control board 91 etc.) on which an element (CPU chip 93 etc.) storing a game control program is mounted, and a plurality of box constituent bodies (back side constituent body 101, front side constituent body 102, intermediate constituent body 103, connector) A control board device (main control device 63, etc.) having a board box (substrate box 92, etc.) which forms an internal space by fixing the plate 104 etc.) to each other and accommodates the control board in the internal space. In a gaming machine equipped with
First trace means (provided so as to be able to be destroyed or removed from the outside of the substrate box, allowing the internal space of the substrate box to be opened when it is destroyed or removed, and leaving a trace of the opening) Box side cutting portion 151 and the like),
Regulating means (intermediate structure 103) provided to restrict the removal of the element from the control board even when the first trace means is destroyed or removed and the internal space of the substrate box is opened. Cover portion 133 etc.),
When the restriction of the removal of the element by the restriction means is released, the game machine is provided with a second trace means (columnar connecting portion 132 or the like) that leaves a trace along with the release of the restriction. .

  According to the means 1, by opening the internal space of the board box, at least a part of the control board is exposed, and the control board can be inspected and maintained. When the control board is exposed in this manner, traces due to the destruction and removal of the first trace means remain, so that it is possible to confirm the fact that the control board is exposed after the inspection or the like. Even when at least a part of the control board is exposed, the removal of the element remains restricted. In order to remove the element, it is necessary not only to open the substrate box but also to release the restricted state by the restricting means. When the restricted state is released, the trace remains by the second trace means.

  In order to remove a main part (that is, an element) that is likely to be a target of fraud, it is easy to check the fact of removal by adopting a configuration with more traces remaining. This contributes to facilitating the discovery of fraud.

  Also, in the case of inspection without element removal, the work can be performed without releasing the restriction by the restriction means, that is, by destroying or removing the first trace means. In this manner, inspection and the like can be performed while maintaining the regulated state of the element, thereby suppressing a reduction in workability.

  The “destruction of the first trace means” means that a part of the member (base material) is broken by the first trace means being cut or the like, making it difficult to return to the state before breaking. Show.

  In addition, “the internal space of the substrate box can be opened” means that the internal space of the substrate box is directly opened (ie, without performing another operation) due to destruction or removal of the first trace means. In addition to indicating that the first trace means is broken or removed, the opening of the internal space of the substrate box is permitted, and other operations such as separating each box component (specifically, It shows that the internal space of the substrate box is opened by the operation without remaining).

  Mean 2. Means 1 is characterized in that the first trace means is destroyed or removed and the internal space of the substrate box is opened, whereby the element removal restriction can be released by the restriction means. The gaming machine described.

  If a predetermined order is set for element removal as shown in this means, it is possible to avoid the inconvenience that the operator erroneously releases the restriction on element removal. Thereby, in the structure which has a some trace means, it can contribute to reduction of work mistakes at the time of an inspection, etc.

  Means 3. When the first trace means is destroyed or removed and the internal space of the substrate box is opened, at least the element mounting surface (element mounting surface 97) on which the element is mounted is exposed. The gaming machine according to means 1 or 2, characterized by the above.

  In general, the control board often has an element mounting surface and a solder surface. Of these surfaces, the solder surface is considered to be hardly subject to inspection or maintenance, while visual confirmation work (for example, confirmation of the presence or absence of additional illegal ROM) is performed. On the other hand, the element mounting surface is subject to inspection and maintenance in addition to visual confirmation. As shown in this means, a practically preferable configuration can be realized if at least the element mounting surface can be exposed by opening the internal space of the substrate box.

  Means 4. The control means is a cover part (cover part 133) that covers the element so that access to the element is impossible or difficult in the internal space of the substrate box. A gaming machine according to any one of the means.

  According to the means 4, the element is covered with the cover portion. Even if a criminal or the like forms a gap or the like in the board box and the illegal tool or the like is inserted through the gap or the like, the illegal tool or the like is blocked by the cover portion. For this reason, inconveniences such as unauthorized access to the element are less likely to occur. That is, by covering the element with the cover portion, it contributes to the improvement of crime prevention.

  Note that “access” indicates physical contact with an element, and includes a case where electrical connection is made based on such physical contact (for example, a lead wire).

  Means 5. The gaming machine according to claim 4, wherein the cover portion forms a closed space with the control board and houses the element in the closed space.

  In order to suppress unauthorized access to the element, as shown in this means, the element may be accommodated in a closed space formed by the cover portion and the control board. Thereby, not only unauthorized removal of the element but also unauthorized access to the element in a state where the control board is exposed can be suitably suppressed, and a practically preferable configuration can be realized.

Means 6. As the plurality of box structural bodies, a first box structural body (for example, the back side structural body 101) and a second box structural body (for example, the front side structural body 102) that form at least a part of the internal space of the substrate box are provided.
The first box configuration body and the second box are formed by combining the first coupling portion provided in the first box configuration body and the second coupling portion provided in the second box configuration body. Both box structures are fixed to prevent separation from the structure,
The first trace means is formed so as to be easily broken so that the internal space of the substrate box can be opened more easily than the case where the combined state of the first and second coupling portions is released to open the internal space of the substrate box. And a weak portion formed so as to partition a predetermined region including a portion facing the cover in the substrate box with respect to the surrounding region. 5. The gaming machine according to 5.

  According to the means 6, since the first trace means has the weak part that is easier to break than the release of the combined state of the first box structure and the second box structure, the work of destroying the weak part Can be done relatively easily. This contributes to improvement in workability when the control board is inspected. The fragile portion is formed so as to partition a predetermined region including a portion facing the cover portion in the substrate box with respect to the surrounding region, so that the cover portion is exposed when the fragile portion is broken. It can be. Specifically, the cover portion can be accessed through an opening formed by destroying the fragile portion. Accordingly, when the restriction by the cover part is released, for example, when the cover part is removed, such a restriction releasing work can be easily performed.

  Further, when the fragile portion is destroyed and the internal space of the substrate box is opened, an opening or the like is easily formed in the substrate box. For this reason, if the fragile part is destroyed and the internal space of the substrate box is opened for the purpose of cheating on the above-described elements, the discovery can be performed relatively easily.

  Furthermore, in the configuration in which the weakened portion is provided as described above, the weakened portion has a function for satisfactorily opening the internal space of the substrate box. This eliminates the need to consider workability when opening the internal space of the substrate box. Therefore, it is possible to firmly fix the plurality of box structures.

  It should be noted that by compromising the fragile portion and forming an opening or the like in the substrate box, a part of the element surface of the control substrate is exposed, thereby making it possible to suppress complications in preparation work such as inspection. Normally, it is assumed that it is efficient to perform various operations such as inspection and maintenance of the element mounting surface from the front side of the element mounting surface, that is, the side facing the element mounting surface. For example, when the fragile portion is provided in a portion other than the portion facing the element mounting surface, the element mounting surface is exposed, but the operation itself may be difficult. However, according to this means, work such as inspection can be performed from the front side of the element mounting surface by breaking or cutting the fragile portion, which can contribute to ensuring workability.

  Mean 7 The gaming machine according to claim 6, wherein the cover part is formed separately from the predetermined area defined by the weak part.

  According to the means 7, since the cover part is formed separately from the area partitioned by the weak part, even if the weak part is destroyed to some extent and the area partitioned by the weak part is bent outward, the cover is covered. The part does not follow it, and the state in which the element is accommodated by the cover part is maintained. If the area defined by the fragile part and the cover part are integrated, there is a concern that the element is exposed from the cover part by bending the fragile part as described above. It is assumed that unauthorized access to the device is likely to be performed. However, in this means, since the area defined by the fragile part and the cover part are separate, the inconvenience is less likely to occur.

Means 8. As the plurality of box structures, including an intermediate structure disposed in the internal space including the cover portion,
Even if the fragile portion is destroyed and the predetermined region is removed, the intermediate structure is interposed between the opening formed in the substrate box and the control substrate. The gaming machine described in 1.

  As an illegal act with respect to the control board device, an act of illegally acquiring the control board and an act of attempting to replace the control board with an illegal board are assumed. In this case, in the configuration provided with the above-described means 7 and the weakened portion provided in the substrate box, the control substrate is to be removed through an opening or the like formed in the substrate box by destroying the weakened portion. To act. On the other hand, according to the present means, even if the fragile portion is destroyed, an intermediate structure is interposed between the control board and the opening formed by destroying the fragile portion. Removal of the control board is prevented. Therefore, it is possible to prevent the illegal acts as described above.

  Means 9. The second trace means is provided so as to be able to be destroyed or removed, and when the second trace means is destroyed or removed, the restriction of removal of the element by the restriction means is released. The gaming machine according to any one of 1 to 8.

  According to the means 9, when the second trace means is destroyed or removed, the restriction state by the restriction means is released, and the trace of the restriction release remains.

  Means 10. The second trace means is a holding portion formed so as to hold the restriction means in a restricted position and to be easily broken rather than to break the restriction means itself. A gaming machine according to claim 9.

  According to the means 10, when the removal of the element is restricted by the restricting means, the restricting means is held at a predetermined position by the holding portion. By destroying the holding portion, it is possible to easily release the element removal restriction.

  In particular, as shown in the means 4 to 8, in the configuration in which the element is covered by the cover portion (regulating means), it is possible to suitably suppress damage to the element due to the release of the restriction. Specifically, when the cover part itself is destroyed or cut by using a tool or the like so that the element can be removed, it is considered that the tool and the element can come into contact with the time of destruction or cutting. The element is a main part that stores the game control program, and it is not desirable to make contact with the tool as described above from the viewpoint of functional maintenance. Therefore, in this means, the holding portion as the second trace is provided separately from the cover portion. For this reason, it is hard to produce inconveniences, such as an element being damaged with the preparation work of element removal. That is, the protection of the element when preparing to remove the element is preferable. Moreover, since the destruction or cutting operation of the holding portion is easier than the destruction or cutting operation of the cover portion, it is possible to reduce the work load caused by the destruction or cutting operation.

Means 11. The first trace means is formed by juxtaposing a plurality of through holes (through holes 152) penetrating in and out of the substrate box,
The substrate box includes a facing portion (frame-shaped portion 131) facing the through hole between the control substrate and the through hole.
The gaming machine according to claim 10, wherein the holding portion connects both the facing portion and the restricting means.

  According to the means 11, the first trace means is formed by arranging a plurality of through holes in parallel. For example, a predetermined region of the substrate box may be partitioned by these through holes. Thereby, the meat | flesh part between through-holes can be destroyed or removed, and a predetermined opening can be formed. That is, the control board can be exposed. By arranging the through holes in this way, it is possible to easily form a portion that can be easily broken.

  However, while it is possible to realize a configuration that can be easily broken by the through holes, it is assumed that a fraudulent jig is inserted into the internal space of the substrate box through the through holes. On the other hand, according to the present means, since the opposing portion is provided on the substrate box, even if the insertion of the fraudulent jig into the internal space of the substrate box is prevented or inserted into the internal space, It is possible to prevent the fraudulent jig from reaching the control board.

  In order to suppress the intrusion of illegal tools or the like, it is considered desirable to have a configuration in which a predetermined strength is imparted to the facing portion and deformation or the like is difficult to occur. Thus, if the part which is hard to produce a deformation | transformation etc. and the control means are connected by a holding part, holding | maintenance of a control means can be made suitable.

  Means 12. The gaming machine according to claim 11, wherein the holding portion is formed in a columnar shape.

  According to the means 12, since the holding portion is formed in a columnar shape, it is possible to obtain an excellent effect in the means 11 while avoiding occupying the internal space in the substrate box as much as possible.

  Means 13. The gaming machine according to claim 12, wherein a predetermined gap is provided between the holding portion and the control board.

  When the opening is formed as the internal space of the board box is opened as described above, and the holding part is destroyed or cut through the opening, the control board side (specifically, the element mounting surface) It is assumed that the load toward the side) is likely to occur. For example, when the holding portion is cut with a tool such as a blade, it is considered that the load generated on the blade edge or the like tends to be directed toward the control board. If an excessive load more than that required for cutting the holding portion is applied, the tool may come into contact with the control board on the timepiece whose holding portion has been cut. However, as shown in this means, if a predetermined gap is provided between the holding portion and the control board, it is possible to easily avoid the inconvenience that the tool comes into contact with the control board. Furthermore, when the gap is set to such an extent that a tool such as a blade can be inserted, the holding part can be cut or broken through the gap between the holding part and the element mounting surface. As a result, a load generated in the holding unit when the holding unit is cut or the like is likely to be generated in a direction away from the control board. Therefore, it is possible to make it difficult for the tool to collide with the control board when the holding part is cut.

  Means 14. The gaming machine according to means 12 or 13, wherein the holding portion extends in a plurality of different directions from the restricting means.

  As shown in the above means, the restricting means restricts removal of the element. In order to easily release the restriction, it is preferable to weaken the strength of the holding portion and facilitate the destruction of the holding portion. However, in such a case, there is a concern that the support strength of the restricting means is reduced, and the displacement of the restricting means is likely to occur. For example, in a state where the substrate box is opened and the control board is exposed, it is difficult to suppress fraud if it is possible to remove the element without breaking the holding portion by pulling the regulating means. It is thought that it becomes. On the other hand, if the holding part is made strong, the original function as the holding part, that is, the function as the fragile part that can be easily broken is impaired. Therefore, as shown in the present means, by configuring the holding portions to extend in a plurality of directions, it is possible to improve the support strength of the regulating means while lowering the strength of each holding portion. Thereby, it can contribute to the improvement of workability | operativity at the time of preparation for element removal, suppressing the fraud as mentioned above.

  Further, by adopting a configuration in which the holding portion extends in a plurality of directions, the other holding portion can be cut or the like while one holding portion is held by a finger or the like. Thereby, workability | operativity can be improved. Further, by suppressing the displacement of the restricting means when the holding portion is cut or the like, the contact between the restricting means and the element can be suitably suppressed. For example, the holding portion may be formed so as to partition the opening into a plurality of regions. More specifically, it is preferable to form a columnar holding portion that extends vertically and horizontally around the restricting means.

Means 15. As the plurality of box structures, a first box structure and a second box structure forming at least a part of the internal space of the substrate box,
The first box configuration body and the second box are formed by combining the first coupling portion provided in the first box configuration body and the second coupling portion provided in the second box configuration body. Both box structures are fixed to prevent separation from the structure,
The first trace means is formed so as to be easily broken so that the internal space of the substrate box can be opened more easily than the case where the combined state of the first and second coupling portions is released to open the internal space of the substrate box. The gaming machine according to any one of means 1 to 14, wherein the gaming machine is a weakened part.

  According to the means 15, since the first trace means has a fragile part that is easier to break than the release of the combined state of the first box structure and the second box structure, the work of destroying the fragile part Can be done relatively easily. This contributes to improvement in workability when the control board is inspected. Furthermore, in the configuration in which the weakened portion is provided as described above, the weakened portion has a function for satisfactorily opening the internal space of the substrate box. This eliminates the need to consider workability when opening the internal space of the substrate box. Therefore, it is possible to firmly fix the plurality of box structures.

Means 16. The fragile portion is provided so as to partition a peripheral wall defining the internal space into a plurality of regions in the substrate box,
An opening that breaks the fragile portion and removes the element by releasing the restriction state by the restriction means when a partial region of the peripheral wall is removed from a position defining the internal space. The gaming machine according to claim 15, wherein the board box is formed on the board box.

  According to the means 16, when the weak part is formed in the board box, and when the weak part is cut and a part of the peripheral wall part defining the internal space is removed, the game control program is stored. An opening is formed in the substrate box that allows the removed element to be removed.

  In addition, when the fragile portion is cut to open the internal space of the substrate box, an opening is formed in the substrate box. If the internal space is open, it can be found relatively easily.

  For example, the fragile portion may be disposed at a portion of the peripheral wall of the substrate box that faces the element mounting surface. Further, a configuration in which an element is disposed between an opening formed by removing the partitioned region and an element mounting surface, that is, a configuration in which a regulating means (cover portion) is interposed between the opening and the element. Thus, a practically preferable configuration can be realized. Thereby, the removal of the element can be made easy after the restriction is released while the removal of the element is restricted by the restriction means. Therefore, it can contribute to security of crime prevention and improvement of workability at the time of inspection.

  Note that the “circumferential wall defining the internal space of the substrate box” may be a part or all of the substrate box. In other words, it may be “a defining portion that defines the internal space of the substrate box” or “a wall portion that defines the internal space of the substrate box in the substrate box”.

  In addition, “the opening that allows the element to be removed is formed in the substrate box” includes not only a structure in which the element is exposed through the opening but also a cover portion that covers the element in the internal space of the substrate box. In this case, the cover portion is exposed by the opening, and the cover portion can be removed in that state, and the element is exposed by removing the cover portion.

  Means 17. The fragile portion is formed with a through hole (through hole 152) penetrating in and out of the substrate box, and air permeability inside and outside of the substrate box is secured by the through hole. The gaming machine according to means 16.

  According to the means 17, the fragile portion can be obtained by a relatively simple configuration in which a through hole is formed in the substrate box. The fragile portion has not only a function for opening the internal space of the board box relatively easily but also a function for improving the air permeability of the board box. Therefore, it is possible to increase the functionality of the fragile portion (that is, the first trace means). When such a through hole is provided, it is assumed that the fraudulent jig is inserted into the internal space of the substrate box through the through hole. In particular, there is a possibility that unauthorized access to the main part (the element or the like) of the main control device may be performed. On the other hand, according to the present means, since the main part of the main control board is at least covered with the cover part, even if an unauthorized tool is inserted through the through-hole, Unauthorized access (arrival) can be suppressed. In particular, as shown in the means 5 and the like, when an element is stored in a closed space formed by the cover portion, unauthorized access to the element can be suitably suppressed, and a practically preferable configuration can be realized. it can.

  Means 18. 18. The gaming machine according to claim 17, wherein the board box includes a facing portion (frame-like portion 131) facing the through hole between the control board and the through hole.

  In the configuration including the above-described means 17 and the first trace means being formed by a through hole, it is assumed that a fraudulent jig is inserted into the internal space of the substrate box through the through hole. On the other hand, according to the present means, since the opposing portion is provided on the substrate box, even if the insertion of the fraudulent jig into the internal space of the substrate box is prevented or inserted into the internal space, It is possible to prevent the fraud jig from reaching the control board.

Means 19. A control board (main control board 91 etc.) on which an element (CPU chip 93 etc.) storing a game control program is mounted, and a plurality of box constituent bodies (back side constituent body 101, front side constituent body 102, intermediate constituent body 103, connector) A control board device (main control device 63, etc.) having a board box (substrate box 92, etc.) which forms an internal space by fixing the plate 104 etc.) to each other and accommodates the control board in the internal space. In a gaming machine equipped with
First trace means (provided so as to be able to be destroyed or removed from the outside of the substrate box, allowing the internal space of the substrate box to be opened when it is destroyed or removed, and leaving a trace of the opening) Box side cutting portion 151 and the like),
Regulating means (such as the cover portion 133 of the intermediate structure 103) that regulates exposure of the element from the control board even when the first trace means is destroyed or removed and the internal space of the substrate box is opened. )When,
When the restriction of the exposure of the element by the restriction means is cancelled, the game machine is provided with second trace means (columnar connecting portion 132 or the like) that leaves a trace along with the release of the restriction. .

  According to the means 19, by opening the internal space of the board box, at least a part of the control board is exposed, and the control board can be inspected and maintained. When the control board is exposed in this way, the first trace means leaves an open trace, so that it is possible to confirm the fact that the main control board is exposed after inspection or the like. Even when at least part of the control board is exposed, the exposure of the element remains regulated. In order to expose the element, it is necessary not only to open the substrate box but also to release the restricted state by the restricting means. When the restricted state is released, the trace remains by the second trace means.

  In order to expose the main part (that is, the element) that is assumed to be a target of fraud, it is easy to confirm the fact that the element has been exposed by adopting a configuration that involves the presence of more traces. This contributes to facilitating the discovery of fraud.

  Even when inspection, maintenance, or the like is performed with the control board exposed, the element exposure can be kept restricted by the restricting means. In this way, by restricting the exposure of the portion (that is, the element) that is likely to be fraudulent when the control board is inspected or the like, it is possible to preferably avoid the inconvenience that the element is attached or detached for the purpose of fraud . This contributes to improved crime prevention.

  As described in detail above, the main part (that is, the element) that is assumed to be subject to fraud is separated from other parts, and the difference is set in the remaining traces according to the subject of exposure. In addition to improving the crime prevention by positively increasing the number of trace confirmation points for exposure of easy-to-be-prone parts, and positively suppressing the trace confirmation points for exposure of parts that are not subject to fraud Contributes to ensuring workability during inspection and maintenance.

  The respective ideas shown in the means 2 to 18 can be applied to the means 19.

Means 20. The first trace means is provided so as to divide a peripheral wall defining the internal space into a plurality of regions in the substrate box, and a through hole (through hole 152) penetrating into and out of the substrate box is predetermined. Is arranged on the line of
The through hole has a long hole shape, and is arranged such that the longitudinal direction of each through hole is along the predetermined line. Game machines.

  According to the means 20, the internal space of the substrate box can be easily opened by breaking the substrate box (for example, cutting) along a predetermined line, that is, along the arranged through holes. . Specifically, an opening or the like is formed in the substrate box by cutting the meat portion between the through holes. If the inner space of the board box is opened by destroying the periphery of the through-hole for the purpose of cheating on the above elements, etc., traces such as openings are formed, so the discovery is relatively easy. Can do.

  In general, if the through-hole is enlarged, the destruction of the substrate box can be facilitated, but on the other hand, it is considered that a fraudulent jig or the like is easily inserted through the through-hole. In this respect, in this means, since the through hole is arranged so that its longitudinal direction is along a predetermined line, it is possible to contribute to facilitating breakage while suppressing an increase in size of the through hole. Thereby, while contributing to facilitation of the internal space of the substrate box, fraud that may occur due to the space can be suitably suppressed.

Means 21. The first trace means is provided so as to divide a peripheral wall defining the internal space into a plurality of regions in the substrate box, and a through hole (through hole 152) penetrating into and out of the substrate box is predetermined. Is arranged on the line of
Any one of the means 2 to the means 14 characterized in that a distance dimension between the through holes arranged side by side is set smaller than a length dimension of the through holes in the juxtaposed direction. A gaming machine according to one means.

  According to the means 21, since the distance dimension between the through holes is set to be smaller than the length dimension of the through holes in the direction in which the through holes are arranged, the board box is broken along a predetermined line (for example, cutting or the like). ) Can be made easy. Specifically, when breaking along a predetermined line, the area occupied by the flesh of the board box to be broken can be reduced, so it is relatively easier than breaking other parts of the board box. Destructive work can be done. Thus, when destruction is performed along a predetermined line, an opening or the like is formed in the substrate box. If the inner space of the board box is opened by destroying the periphery of the through-hole for the purpose of cheating on the above elements, etc., traces such as openings are formed, so the discovery is relatively easy. Can do.

  In the means 20 and the means 21, for example, a through hole may be disposed in a portion of the peripheral wall of the substrate box facing the element mounting surface. Further, a configuration in which an element is disposed between an opening formed by removing the partitioned region and an element mounting surface, that is, a configuration in which a regulating means (cover portion) is interposed between the opening and the element. Thus, a practically preferable configuration can be realized. Thereby, the removal of the element can be made easy after the restriction is released while the removal of the element is restricted by the restriction means. Therefore, it can contribute to security of crime prevention and improvement of workability at the time of inspection.

  Note that the “peripheral wall defining the internal space of the substrate box” in the means 20 and 21 may be a part or all of the substrate box. In other words, it may be “a defining portion that defines the internal space of the substrate box” or “a wall portion that defines the internal space of the substrate box in the substrate box”.

  The technical idea of the means 20 can be applied to the means 21.

The intermediate structure 103 is disposed, and in this state, each combination of the fixing flange 134 and the fixing boss 135 is screwed from the back side of the front-side structure 102. This screwing is performed by a break screw 136, and the head of the break screw 136 is separated after screwing. Note that a one-way screw may be used instead of the breaking screw 136.

  The front-side structure 102 in which the intermediate structure 103 and the connector plate 104 are integrated covers the element mounting surface 97 of the main control board 91 with respect to the back-side structure 101 in which the main control board 91 is integrated. Are combined. In this case, the back side peripheral part 112 of the back side structural body 101 and the front side peripheral part 121 of the front side structural body 102 overlap, and the open part to the back surface side of the front side structural body 102 is blocked by the back side structural body 101. Various elements mounted on the element mounting surface 97 of the main control board 91 are accommodated in a region between the main control board 91 and the front side structure 102.

  Here, the intermediate structure 103 in which the cover part 133 is integrally formed as described above is fixed to the front-side structure 102, and the CPU chip mounted on the element mounting surface 97 in the cover part 133 of the intermediate structure 103. 93 has entered. Further, the opening peripheral edge portion of the cover portion 133 is in contact with the element mounting surface 97. That is, a closed space is formed by the cover portion 133 and the main control board 91, and the CPU chip 93 is accommodated in the closed space (see FIG. 10A). As a result, even if a fraudulent gap is formed in the boundary portion between the back side structure 101 and the front side structure 102 and a fraudulent jig such as a wire is inserted into the board box 92 from there, It becomes possible to prevent the jig from accessing the CPU chip 93. Further, the removal of the CPU chip 93 is restricted.

  Since the cover part 133 is firmly fixed to the frame-like part 131 via the three columnar connecting parts 132, an attempt is made to move the cover part 133 using a fraudulent jig inserted into the internal space of the board box 92. Even that is hard to do. Incidentally, three columnar connecting portions 132 are provided instead of four, and are further provided in a column shape so as not to block the opening of the frame-shaped portion 131 as much as possible. Therefore, in the configuration in which the intermediate structure 103 is provided, a reduction in the degree of freedom regarding the arrangement of various elements on the element mounting surface 97 is suppressed.

  In a state where the back side structure 101 and the front side structure 102 are combined, a predetermined connector mounted on the element mounting surface 97 enters the corresponding through hole 125 of the connector plate 104. In this state, the connector is exposed on the surface side of the front structure 102. The position of the predetermined connector on the main control board 91 may be changed for each model. In such circumstances, the connector plate 104 is provided as described above, so that only the connector plate 104 is changed for each model. The front-side structure 102 and the back-side structure 101 can be made common for each model.

  Incidentally, the plate-like portion 127 in which the through hole 125 of the connector plate 104 is formed is superposed on the element mounting surface 97 of the main control board 91 and is provided upright from the plate-like portion 127 of the connector plate 104. The raised portion 128 overlaps the partition wall 124 of the bulging portion 122 inside the bulging portion 122. Accordingly, in the configuration in which the connector plate 104 is provided as described above, the element mounting surface 97 of the main control board 91 is covered with the front side structure 102 and the connector plate 104 except for the connector, as shown in FIG. It has been broken.

  The back side structure 101 and the front side structure 102 are fixed to each other in the combined state as described above. Thus, a rectangular box-like (substantially rectangular parallelepiped) substrate box 92 having a predetermined internal space is formed, and the main control substrate 91 is accommodated in the internal space of the substrate box 92. In this case, the entire element mounting surface 97 of the main control board 91 is opposed to the front side structure 102 in which the intermediate structure 103 and the connector plate 104 are integrated, and the solder surface 98 of the main control board 91 is The whole is opposed to the back side structure 101.

  As shown in FIG. 5, the main controller 63 having the above configuration is configured so that the surface of the front structure 102 faces the back of the pachinko machine 10 and the edge on the side where the connector plate 104 is provided is positioned on the upper side. It is installed. Incidentally, when the gaming machine main body 12 is opened from the outer frame 11 to the front of the pachinko machine 10 in the state of being installed in the game hall, the back side of the gaming machine main body 12 can be visually recognized. In this case, the main control device 63 constitutes the back portion of the gaming machine main body 12, and further, since the surface of the front structure 102 faces the back of the pachinko machine 10 as described above, By opening to the frame 11, the surface of the front structure 102 can be visually recognized. The main controller 63 may be entirely or partially covered with the back pack unit 15 from the rear. Even in this case, since the back pack 71 is formed to be transparent, the surface of the front structure 102 can be visually recognized by opening the gaming machine body 12 with respect to the outer frame 11.

  Next, a configuration related to fixing the back side structure 101 and the front side structure 102 will be described in detail. As a fixing means for the front side structure 102 and the back side structure 101, (1) an adhesive, (2) a caulking structure, and (3) a sealing seal are provided. Therefore, each of these fixing means will be described individually.

  The adhesive is applied so as to fill the entire circumference of the boundary between the back side peripheral edge portion 112 of the back side structural body 101 and the front side peripheral edge portion 121 of the front side structural body 102. Thereby, the back side peripheral part 112 and the front side peripheral part 121 are adhere | attached, and the back side structural body 101 and the front side structural body 102 are being fixed. Moreover, the boundary between the back side peripheral part 112 and the front side peripheral part 121 is filled. This makes it difficult to insert a fraudulent jig into the internal space of the substrate box 92 from the boundary portion between the back side peripheral edge portion 112 and the front side peripheral edge portion 121.

  In addition, as an adhesive agent, a well-known adhesive agent can be used if the back side structural body 101 and the front side structural body 102 can be fixed, for example, an acrylic resin adhesive, a urethane resin adhesive, Ethylene-vinyl acetate resin adhesives, epoxy resin adhesives, silicone adhesives, etc. may be used, and these adhesives may be any of reaction systems, solution systems, water dispersion systems, and solid systems .

  Next, the caulking structure described above will be described.

  As shown in FIG. 9, the caulking structure includes a back side coupling portion 141 provided in the back side configuration body 101 and a front side coupling portion 142 provided in the front side configuration body 102. The back side coupling portion 141 is provided for each of a pair of opposing sides in the back side peripheral edge portion 112 of the back side structure 101. Specifically, a plurality of (specifically, two) back side coupling portions 141 are provided with respect to one short side portion of the back side structure 101, and the short side portion facing the short side portion is provided. One is provided. The back side coupling portion 141 is integrally formed with the flat surface portion 111, and the back side coupling portion 141 itself is formed relatively thick, and a fragile part is formed at the connecting portion between the back side coupling portion 141 and the flat surface portion 111. It has not been.

  The front side coupling portion 142 is provided in one-to-one correspondence with the back side coupling portion 141. That is, the front-side structure 102 is provided with the front-side coupling portions 142 at positions that overlap the back-side coupling portions 141 and the substrate box 92 in the thickness direction. The front side coupling portion 142 is integrally formed with the front side peripheral edge portion 121, and the front side coupling portion 142 itself is formed relatively thick, and is weak at the connection portion between the front side coupling portion 142 and the front side peripheral edge portion 121. Is not formed. The numbers of the back side coupling portions 141 and the front side coupling portions 142 are not limited to those described above, and are arbitrary as long as the back side configuration body 101 and the front side configuration body 102 can be fixed.

  Screw holes that communicate with each other on the same axis are formed in the pair of coupling portions 141 and 142, and a break screw 143 is screwed into the communicating screw holes from the front side coupling portion 142 side. . A plurality of combinations of the back side coupling portion 141 and the front side coupling portion 142 are provided as described above, and all the combinations are coupled by the breaking screw 143. All of the breaking screws 143 have their heads separated. Note that a one-way screw may be used instead of the breaking screw 143.

  Since the back side coupling part 141 and the front side coupling part 142 are coupled as described above, the back side structural body 101 and the front side structural body 102 are fixed to each other in an inseparable state. And since the head of the breaking screw 143 which couple | bonds both the coupling parts 141 and 142 is isolate | separated, the said breaking screw 143 cannot be loosened. Moreover, both the coupling parts 141 and 142 are formed to be relatively thick as described above, and further, no fragile part that facilitates separation from each of the components 101 and 102 is formed. Therefore, it is substantially difficult to release the fixation of the back side structural body 101 and the front side structural body 102 due to the coupling of the coupling portions 141 and 142.

  In addition, when at least one of the coupling parts 141 and 142 is broken in order to release the fixation of the two structural members 101 and 102 by the coupling of the coupling parts 141 and 142, the broken part is the opening of the substrate box 92. It will remain as a trace. That is, the opening history of the substrate box 92 remains. As a result, if the board box 92 is illegally opened, it can be found.

  Next, the seal seal 145 will be described.

  As shown in FIG. 8, a back side adhesive plate portion 146 is integrally formed between the back side connecting portions 141 on the short side portion where two back side connecting portions 141 are provided in the back side peripheral edge portion 112 of the back side structure 101. At the same time, a front-side sticking plate portion 147 is integrally formed at a position overlapping the back-side sticking plate portion 146 and the thickness direction of the substrate box 92 in the front-side peripheral portion 121 of the front-side structure 102.

  A plurality of sets of screw holes communicating with each other are formed in both the pasting plate portions 146 and 147, and screws (not shown) are screwed into these screw holes. As the screw, a detachable known screw is used. By attaching the screws as described above, both the pasting plate portions 146 and 147 are fixed. Further, as shown in FIG. 7, a sealing seal 145 is pasted on the pasting plate portions 146 and 147 so as to straddle the boundary between the both. When the seal seal 145 is peeled off after being stuck, the pressure-sensitive adhesive layer remains on the side of the sticking plate portions 146 and 147, and re-sticking becomes impossible. By providing the seal seal 145, if the substrate box 92 is illegally opened, it can be detected.

  Incidentally, as shown in FIG. 7, a seal cover 148 is fixed to both the sticking plate portions 146 and 147 so as to cover the sealed seal 145 attached from the outside. The seal cover 148 is formed of a transparent synthetic resin, and the seal seal 145 can be visually recognized through the seal cover 148. Note that the seal cover 148 may be omitted. Further, as the sealing sticker 145, a seal having an IC tag that transmits a response wave including unique ID information in response to a calling wave from a predetermined scanner may be used.

  Next, an opening easy structure for easily opening the substrate box 92 will be described. In the following description, FIGS. 10 to 12 will be referred to as appropriate in addition to FIGS. FIG. 10A is a longitudinal sectional view of the substrate box 92 for explaining the opening easy structure, and FIG. 10B is an enlarged view of a part of the front of the substrate box 92 for explaining the opening easy structure. It is explanatory drawing shown. Moreover, FIG.11 and FIG.12 is explanatory drawing for demonstrating an opening easy structure.

  As shown in FIG. 7, a box-side cut portion (box-side weak portion) 151 is formed on the surface constituting portion 126 of the front-side constituting body 102 so as to partition a predetermined region of the surface constituting portion 126. Yes. The box-side cutting portion 151 includes a large number (or a plurality of) through-holes 152 formed so as to penetrate the surface constituting portion 126 into and out of the substrate box 92.

  Specifically, a large number of through holes 152 are formed at equal intervals along the periphery of the surface constituting portion 126, and the large number of through holes 152 are arranged so as to surround a predetermined region of the surface constituting portion 126. That is, the box-side cutting part 151 is formed in an intermittent ring surrounding a predetermined region of the surface constituting part 126. In other words, an intermittent annular cutting guide line is formed as the box-side cutting portion 151. These through holes 152 have a long hole shape, and are arranged so that the longitudinal direction thereof follows the cutting guide line. By arranging the through hole 152 in this way, it is possible to contribute to facilitating cutting while suppressing an increase in the size of the through hole 152. The box-side cutting portion 151 is formed in a rectangular frame shape, specifically, a rectangular frame shape. In addition, the area defined by the box-side cutting part 151 in the surface constituent part 126 is an area facing the CPU chip 93 of the main control board 91 and its periphery in the surface constituent part 126. Note that the through-hole 152 may have a round hole shape. However, in such a case, there is a concern that the size of the hole directly leads to easy insertion of an unauthorized jig or the like. That is, by increasing the hole diameter, it is possible to increase the area occupied by the flesh on the cutting guide line, which facilitates the cutting operation, but increases the hole diameter, thereby making it easy to insert an illegal jig or the like. Can be. In this regard, if the through hole 152 is formed in a long hole shape as described above, it is possible to increase the occupied area of the meat part on the cutting guide line while ensuring the difficulty of inserting an unauthorized jig or the like. Therefore, it is preferable that the through hole is formed in a long hole shape extending along the cutting guide line.

  Incidentally, the box side cutting portion 151 is formed at the same time when the front side structure 102 is molded by a mold (injection molding). That is, the mold for forming the through hole 152 of the box side cutting part 151 is provided in the mold of the front side structure 102. In this case, since the through hole 152 of the box-side cut portion 151 is formed only in the surface constituting portion 126 in the front-side structure 102, the front side having the box-side cut portion 151 is not incurred without complicating the mold structure. The structure 102 can be easily formed. That is, since the front side structural body 102 has a bulging portion 122 and is formed in a box shape opened to one side, the direction in which the front side structural body 102 is removed after molding is naturally defined in the mold. In this case, since the through-hole 152 of the box-side cutting part 151 is formed so as to penetrate the surface constituent part 126 in the thickness direction of the surface constituent part 126, the above-described extraction direction of the front-side constituent body 102 and the through-hole 152 are formed. The penetration direction is the same direction. Therefore, the mold structure of the front side structure 102 can be prevented from becoming complicated.

  The interval between the adjacent through holes 152 is set so that the region between the adjacent through holes 152 can be easily cut by a tool such as a nipper or a cutter. Specifically, the distance between the through holes 152 is set to be smaller than the length of the through holes 152 in the longitudinal direction. As a result, the box-side cutting part 151 is a weaker area in the surface constituting part 126 than other parts. In other words, by fixing the back side structure 101 and the front side structure 102 by the connection of the back side connection part 141 and the front side connection part 142, by destroying at least one of the connection parts 141, 142 or the breaking screw 143, The box side cutting portion 151 is formed to be easier to cut than to open the internal space of the substrate box 92 so that the internal space can be easily opened.

  By cutting the box-side cutting portion 151 over the entire circumference, as shown in FIGS. 11 and 12, the area partitioned by the box-side cutting portion 151 (hereinafter also referred to as a box-side removal region 153) is the front side. It becomes possible to remove from the structure 102, and it becomes possible to open the internal space of the board | substrate box 92 by removing. In this case, the box-side removal region 153 is entirely separated from the front-side structure 102, and as shown in FIG. 11, the front-side structure 102 is formed with a rectangular shape, specifically, a rectangular opening 154. . The long side portion of the opening 154 is along the long side portion of the surface constituting portion 126, and the short side portion of the opening 154 is along the short side portion of the surface constituting portion 126.

  The box-side cutting portion 151 is formed at a position facing the frame-shaped portion 131 of the intermediate structure 103. Specifically, as shown in FIG. 10A, the intermediate structure 103 is accommodated in the internal space of the substrate box 92, and the box side cutting is performed at a position facing the frame-shaped portion 131 of the intermediate structure 103. All the through holes 152 of the part 151 are arranged. The entirety of each through hole 152 is opposed to the frame-like portion 131.

  In this case, as shown in FIG. 10A, the opening on the internal space side of the substrate box 92 in each through hole 152 is separated from the frame-shaped portion 131. That is, each through-hole 152 is not blocked by the frame-shaped portion 131. Thereby, the function as a vent of the board box 92 is fulfilled by the through hole 152 that forms the box side cut portion 151.

  However, the distance between each through-hole 152 and the frame-like portion 131 is set to be relatively small. Even if a fraudulent jig such as a wire is inserted into the substrate box 92 through the through-hole 152, the fraud Even if the tip of the jig for jig hits the frame portion 131 and tries to enter further into the internal space of the substrate box 92, it is difficult to do so.

  Further, as shown in FIGS. 8 and 10A, a groove portion 155 is formed on the surface of the frame-shaped portion 131 that faces the box-side cutting portion 151 so as to be recessed toward the main control board 91 side. The groove portion 155 has a bottom on the main control board 91 side and is formed so as to be opened toward the box side cutting portion 151 side. Further, the groove portion 155 is continuous along the entire circumference of the frame-shaped portion 131. Is formed. Since the groove portion 155 is formed as described above, even if a fraudulent jig such as a wire is inserted into the substrate box 92 through the through hole 152, the fraudulent jig is the groove portion 155 of the frame-shaped portion 131. Get inside. If it does so, even if it tries to infiltrate a fraudulent tool so that the frame-shaped part 131 may be bypassed, it will become difficult.

  By cutting the box-side cutting portion 151 and removing the box-side removal region 153, the internal space of the substrate box 92 is opened as described above. In this case, as shown in FIG. 11, the element mounting surface 97 of the main control board 91 is exposed. However, in this state, since the intermediate structure 103 is still built in the substrate box 92, the CPU chip 93 mounted on the element mounting surface 97 is covered with the cover portion 133 of the intermediate structure 103. Yes.

  Here, a configuration in which the intermediate structure 103 is not provided or the cover portion 133 is integrally formed with the box-side removal region 153 is conceivable. In this case, the CPU chip 93 can be exposed at the timing when the box-side removal region 153 is removed. However, in this configuration, when a part of the box-side cutting part 151 is cut and the box-side removal area 153 is bent outward, the cover part 133 together with the box-side removal area 153 has the cover part 133 of the main control board 91. It moves in a direction away from the element mounting surface 97. Then, the CPU chip 93 can be easily accessed by inserting the fraudulent jig into the substrate box 92 with the box-side removal region 153 bent outward. On the other hand, in the present pachinko machine 10, since the cover portion 133 is provided separately from the box-side removal region 153 as described above, even if the box-side removal region 153 is bent outward, the cover portion 133 is The CPU chip 93 is prevented from being accessed as described above without being separated from the mounting surface 97.

  In the configuration in which the CPU chip 93 is covered with the cover portion 133 of the intermediate structure 103, the box-side cutting portion 151 is cut to remove the box-side removal region 153 from the front-side structure 102, and then each columnar connection of the intermediate structure 103 By cutting the part 132, the cover part 133 can be removed, and by removing the cover part 133, the CPU chip 93 is exposed. Then, by exposing the CPU chip 93, the CPU chip 93 can be removed from the main control board 91.

  Thus, when cutting each columnar connecting portion 132, the columnar connecting portion 132 other than the target for cutting is gripped by one hand and the cutting operation is performed by the other hand (specifically, a tool or the like). It is good to do. Accordingly, it is possible to suppress the occurrence of inconvenience that the cutting target moves due to the cutting force being applied to the cutting target, and to facilitate the cutting work. Further, by holding the cover part 133 side from the cutting position in the columnar connecting part 132, the occurrence of inconvenience that the cover part 133 separated by the cutting of the columnar connecting part 132 hits the CPU chip 93 or the like is suppressed. be able to.

  Incidentally, as shown in FIG. 9, the columnar connecting portion 132 has a groove 156 formed over the entire length of the columnar connecting portion 132, and the wall defining the groove 156 is formed to be relatively thin. Has been. Therefore, the columnar connecting portion 132 can be cut relatively easily. In particular, when the columnar connecting portion 132 is cut, the columnar connecting portion 132 can be cut using a tool for cutting the box-side cutting portion 151.

  In addition, a predetermined gap is formed between each columnar connecting portion 132 and the element mounting surface 97 (see FIG. 11 and the like). Therefore, even when an excessive load is applied toward the element mounting surface 97 when the columnar connecting portion 132 is cut, it is difficult to cause inconvenience that the cutting edge of the tool contacts the element mounting surface 97. It has become. Thereby, the element mounting surface is protected. Since a space is provided between the columnar connecting part 132 and the element mounting surface 97, it is possible to apply a tool to the columnar connecting part 132 from the element mounting surface 97 side. Accordingly, it is possible to avoid a load from being applied toward the element mounting surface 97 when the columnar connecting portion 132 is cut, and to appropriately prevent contact with the element mounting surface 97 due to a work mistake or the like. For example, a nipper or the like may be used as a tool.

  On the other hand, the main control board 91 cannot be taken out from the board box 92 even if the box-side removal region 153 and the cover part 133 are removed. That is, the main control board 91 is fixed to the back side structure 101 using the breaking screw 117 as described above. Further, at least the long side portion of the main control board 91 is longer than the long side portion of the box side removal region 153, that is, the long side portion of the opening formed in the substrate box 92 by removing the box side removal region 153. The length dimension is set large. Therefore, as shown in FIG. 10B, when the box-side removal region 153 is projected on the main control board 91 side, the peripheral edge of the main control board 91 protrudes outward from the projected area. . And the area | region which protruded in the main control board 91 exists in the at least one pair of opposing both ends. Furthermore, the region of the main control board 91 that protrudes from both ends faces the front side peripheral portion 121 of the front side structure 102 and is fixed to the region facing the front side peripheral portion 121 by the breaking screw 117. The site exists.

  With the above configuration, the main control board 91 cannot be taken out from the board box 92 even if the box-side removal region 153 and the cover portion 133 are removed. As a result, in the configuration in which the box-side removal region 153 is provided in the front-side structure 102 as described above, even if it is attempted to easily obtain the genuine main control board 91 by removing the box-side removal region 153, it is difficult to do so. It becomes possible to do.

  In the configuration in which the removal of the main control board 91 is restricted, the main control board 91 is formed with a board-side cutting portion 161 as shown in FIGS. 8 and 10B. The substrate-side cutting portion 161 is configured by a large number (or a plurality of) through-holes 162 formed so as to penetrate the main control substrate 91 in the thickness direction.

  Specifically, the large number of through holes 162 are formed at equal intervals along the periphery of the main control board 91, and the large number of through holes 162 are arranged so as to surround a predetermined region of the main control board 91. That is, the substrate side cutting portion 161 is formed in an intermittent annular shape surrounding a predetermined region of the main control board 91. In other words, an intermittent annular cutting guide line is formed as the substrate-side cutting portion 161. Moreover, the board | substrate side cutting part 161 is formed in the rectangular frame shape, specifically, the rectangular frame shape. Various elements and connectors including the CPU chip 93 mounted on the main control board 91 are all included in an area partitioned by the board-side cutting unit 161.

  As shown in FIG. 8, the CPU chip 93 is installed within the area defined by the substrate-side cutting portion 161 (hereinafter referred to as “substrate-side removal area 163”), whereas the back-side structure using the breaking screw 117. The fixed portion of the main control board 91 with respect to 101 is outside the range of the board-side removal area 163. Moreover, the space | interval between the adjacent through-holes 162 in the board | substrate side cutting part 161 is set so that the area | region between the adjacent through-holes 162 can be easily cut | disconnected by tools, such as a nipper and a cutter. Incidentally, the through hole 162 of the substrate side cutting part 161 and the through hole 152 of the box side cutting part 151 have the same opening area, and further, the distance between adjacent through holes 162 in the substrate side cutting part 161 is This distance is the same as the distance between adjacent through holes 152 in the box-side cut portion 151. Therefore, the substrate side cutting part 161 can be cut using a tool for cutting the box side cutting part 151. The box side cutting unit 151 and the substrate side cutting unit 161 may be configured to require different tools.

  The area of the substrate side removal region 163 is set smaller than the area of the box side removal region 153. Further, as shown in FIG. 10B, the substrate-side removal region 163 is formed so as to be included within the range of the projected region when the box-side removal region 153 is projected onto the main control substrate 91 side. Has been. Therefore, by removing the box-side removal region 153, the entire substrate-side removal region 163, that is, the entire substrate-side cutting portion 161 is exposed. And in this state, while cutting each columnar connection part 132 of the intermediate structure 103 from the base by the side of the frame-shaped part 131, by cutting the board | substrate side cutting part 161, the box side removal area | region 153 is removed. The substrate-side removal region 163 can be taken out through the opening 154 formed in the substrate box 92. In this case, since the entire substrate side cutting portion 161 is exposed through the opening 154, it is easy to perform the cutting operation of the substrate side cutting portion 161 and the removal operation of the substrate side removal region 163.

  Here, as shown in FIG. 10B, at least the wiring pattern 164 on the element mounting surface 97 side of the main control board 91 has a part of the wiring 165 constituting the wiring pattern 164 straddling the board-side cutting portion 161. It is formed in this way. That is, the wiring 165 is formed so as to straddle the region between the adjacent through holes 162 in the substrate-side cutting part 161. Therefore, when the substrate-side cutting portion 161 is cut to take out the substrate-side removal region 163 from the substrate box 92, the wiring pattern 164 of the main control board 91 is disconnected. As a result, even if the substrate side removal region 163 is returned to the original position after the substrate side cutting portion 161 is cut and the substrate side removal region 163 is taken out, the disconnected state of the wiring pattern 164 is maintained. The main control board 91 does not function normally. Therefore, even if an illegal act of taking out the substrate-side removal region 163 from the substrate box 92 and improperly performing the substrate-side removal region 163 and then returning it to the original position, the main control board 91 is in normal operation. It becomes possible to effectively invalidate the fraudulent behavior by not functioning properly.

  Next, a description will be given of an operation in the case where the CPU chip 93 is taken out from the board box 92 in order to perform an inspection at the game hall. FIG. 13 is an explanatory diagram for explaining the operation when the CPU chip 93 is taken out from the substrate box 92.

  When the CPU chip 93 is inspected in the game hall, the main controller 63 is taken out from the gaming machine main body 12 as shown in FIG. Thereafter, as shown in FIG. 13B, the box-side cutting portion 151 of the front-side structure 102 is cut to remove the box-side removal region 153. As a result, the inside of the substrate box 92 is opened, and the intermediate structure 103 and the element mounting surface 97 of the main control board 91 are exposed.

  Thereafter, as shown in FIG. 13C, the cover 133 can be removed by cutting each columnar connecting portion 132 of the intermediate structure 103, and the CPU chip 93 can be removed by removing the cover 133. Is exposed. In this case, since each columnar connecting part 132 can be cut using a tool for cutting the box side cutting part 151, the work of exposing the CPU chip 93 can be performed relatively easily. Since the CPU chip 93 is not soldered to the main control board 91 as described above, by pulling out the CPU chip 93 in the direction facing the element mounting surface 97, as shown in FIG. Can be taken out. Thereby, the inspection of the CPU chip 93 can be performed carefully.

  Next, a description will be given of an operation in the case where the substrate side removal region 163 of the main control substrate 91 is taken out from the substrate box 92 in order to perform inspection at the game hall. FIG. 14 is an explanatory diagram for explaining the state of work when the substrate-side removal region 163 of the main control board 91 is taken out from the board box 92.

  When the main control board 91 is inspected in the game hall, the main control device 63 is taken out from the gaming machine main body 12 as shown in FIG. Thereafter, as shown in FIG. 14B, the box side cutting portion 151 of the front side structure 102 is cut to remove the box side removal region 153. As a result, the inside of the substrate box 92 is opened, and the intermediate structure 103 and the element mounting surface 97 of the main control board 91 are exposed.

  After that, as shown in FIG. 14C, each columnar connecting portion 132 of the intermediate structure 103 is cut from the root on the frame-like portion 131 side, and as shown in FIG. The substrate side cutting part 161 is cut. Thereby, the substrate-side removal region 163 of the main control board 91 can be taken out, and the inspection of the substrate-side removal region 163 in the main control board 91 can be carefully performed. In this case, since the substrate side cutting portion 161 can be cut using a tool for cutting the box side cutting portion 151 and each columnar connecting portion 132, the operation of taking out the substrate side removal region 163 is performed relatively easily. be able to.

  Here, in the configuration in which the CPU chip 93 and the substrate-side removal region 163 can be easily removed from the substrate box 92 as described above, the CPU chip 93 or the The main control board 91 can be easily taken out for illegal purposes. On the other hand, as described above, when the CPU chip 93 is taken out from the substrate box 92, it is necessary to remove the box-side removal region 153 from the substrate box 92, and a large opening 154 is formed in the substrate box 92. It becomes. Then, if the CPU chip 93 is taken out for illegal purposes, it can be easily found.

  Further, as described above, when the main control board 91 is taken out from the board box 92, it is necessary to remove the box-side removal region 153 from the board box 92, and the board-side cutting portion 161 is cut to remove the board from the main control board 91. The side removal region 163 needs to be taken out. By removing the box side removal region 153 from the substrate box 92, a large opening 154 is formed in the substrate box 92. Further, by taking out the substrate-side removal region 163 from the main control board 91, a large opening is formed in the main control board 91. Then, if the main control board 91 has been taken out for illegal purposes, it is confirmed by checking at least one of the opening 154 formed in the board box 92 or the opening formed in the main control board 91. Can be easily discovered.

  Next, a configuration for temporarily housing the CPU chip 93 and the main control board 91 in the board box 92 after the inspection of the CPU chip 93 and the main control board 91 will be described.

  First, a configuration for temporarily housing the CPU chip 93 in the substrate box 92 after taking out only the CPU chip 93 will be described.

  As already described, a plurality of box temporary fixing bosses 116 are integrally formed on the back side structural body 101, and each box temporary fixing boss 116 is formed with a screw hole. As shown in FIG. 11 and FIG. 12, box temporary fixing bosses 171 are integrally formed at the four corners of the box side removal region 153 of the substrate box 92 in a one-to-one correspondence with the box temporary fixing bosses 116. ing. The box temporary fixing boss 171 extends from the back surface of the box-side removal region 153 toward the back-side component 101 and has a screw hole. The screw hole passes through the box temporary fixing boss 171 and is opened on the front side of the box-side removal region 153.

  After removing the box-side removal region 153 and the cover part 133 and taking out the CPU chip 93, the CPU chip 93 is attached to the main control board 91 again, and the box-side removal region 153 is placed at the original position of the substrate box 92. To place. In this case, the box temporary fixing bosses 171 corresponding to the box side removal regions 153 overlap with the box temporary fixing bosses 116 of the back side structure 101, and the screw holes of both the bosses 116 and 171 are communicated. In this state, by screwing a break screw from the front side of the box side removal region 153, the box side cutting portion 151 is cut, but the CPU chip 93 and the main control board 91 are accommodated in the board box 92. It will be in the state.

  Here, after the CPU chip 93 is taken out of the board box 92 and carefully inspected at the game hall, the CPU chip 93 may be re-inspected by the gaming machine manufacturer. In this case, the test result of the CPU chip 93 may be abnormal, and the CPU chip 93 may be illegally exchanged. In such a case, assuming that the main control device 63 is transported to the gaming machine manufacturer with the opening 154 formed in the board box 92, the CPU chip 93 is damaged during the transport, and the CPU chip 93 is restored. There is a possibility that the inspection cannot be performed. On the other hand, by causing the box side removal region 153 to close the opening 154 of the substrate box 92 again as described above, the occurrence of breakage of the CPU chip 93 during the conveyance is suppressed.

  Further, it is assumed that an unauthorized person who has illegally exchanged the CPU chip 93 exchanges it again with a regular CPU chip 93 during the transfer of the main control device 63 to the gaming machine manufacturer. On the other hand, by screwing the box-side removal region 153 with a break screw as described above, it is difficult to remove the box-side removal region 153, and it is difficult to perform an act of trying to replace the regular CPU chip 93 again. Is possible.

  Note that as a disadvantage during the transfer of the main controller 63 to the gaming machine manufacturer, when only the former is assumed, the box-side removal region 153 need not be temporarily fixed, but a well-known removable screw. Can be used.

  Next, a configuration for temporarily housing the substrate side removal region 163 in the substrate box 92 after taking out the substrate side removal region 163 of the main control board 91 will be described.

  As already described, a plurality of temporary substrate fixing bosses 115 are integrally formed on the backside structure 101, and each substrate temporary fixing boss 115 is formed with a screw hole. As shown in FIG. 8, temporary fixing through holes 172 are formed at four corners of the substrate-side removal region 163 so as to correspond to the temporary fixing bosses 115 on a one-to-one basis.

  After removing the columnar connecting portions 132 including the box-side removal region 153 and the cover portion 133, and cutting the substrate-side cutting portion 161 to take out the substrate-side removal region 163, the substrate-side removal region 163 is moved to the back side. It is arranged at the original position on the structure 101. In this case, the temporary fixing through holes 172 corresponding to the box-side removal regions 153 communicate with the screw holes of the substrate temporary fixing boss 115 of the back side structure 101. In this state, the substrate-side removal region 163 is formed with respect to the back-side structure 101, although the substrate-side cutting portion 161 is cut by screwing the breaking screw from the element mounting surface 97 side of the substrate-side removal region 163. Fixed. Thereafter, as already described, the box side cutting area 151 is cut by temporarily fixing the box side removal region 153 through the box temporary fixing bosses 116 and 171, but the CPU chip 93 and the main control board 91 are cut. Is housed in the substrate box 92.

  Here, there is a case where the board side removal area 163 of the main control board 91 is taken out of the board box 92 and carefully inspected at the game hall, and then the board side removal area 163 is re-inspected by the gaming machine manufacturer. As this case, it is conceivable that the inspection result of the substrate-side removal region 163 is abnormal and the main control board 91 has been illegally replaced. In such a case, assuming that the main control device 63 is transported to the gaming machine manufacturer with the opening 154 formed in the substrate box 92, the substrate-side removal region 163 is damaged during the transportation and the substrate-side removal is performed. There is a possibility that the re-inspection of the area 163 cannot be performed. The same applies to the case where the substrate side removal region 163 is not fixed in the substrate box 92. On the other hand, the substrate-side removal region 163 is fixed to the back-side component 101 as described above, and the opening 154 of the substrate box 92 is closed again by the box-side removal region 153, so that the substrate-side removal region in the middle of the conveyance is obtained. The occurrence of breakage of 163 is suppressed.

  In addition, it is assumed that an unauthorized person who has illegally exchanged the main control board 91 exchanges the main control board 63 with the regular board-side removal area 163 during the transfer of the main control apparatus 63 to the gaming machine manufacturer. On the other hand, as described above, the box side removal region 153 and the substrate side removal region 163 are screwed with the breaking screws, so that it becomes difficult to remove the box side removal region 153 and the substrate side removal region 163. It is possible to make it difficult to perform an action to replace the removal area 163.

  In addition, as the inconvenience during the transfer of the main controller 63 to the gaming machine manufacturer, when only the former one is assumed, the temporary fixing of the box-side removal region 153 and the substrate-side removal region 163 does not need to be a breaking screw. What is necessary is just to perform using the detachable known screw.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 15, 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 via 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.

  A box-side cutting portion 151 is formed in the substrate box 92 of the main control device 63, and the box-side cutting portion 151 is cut to remove the box-side removal region 153 from the position defining the internal space. In this case, an opening 154 that allows the removal of the CPU chip 93 storing the game control program is formed in the board box 92. Since the box-side cutting portion 151 is formed so as to be easier to cut than when the fixed state between the back-side structure 101 and the front-side structure 102 is released, the CPU chip 93 is taken out of the board box 92 and carefully selected in the game hall. In the case of inspection, the operation can be performed relatively easily.

  Further, when the box-side cutting portion 151 is cut to open the internal space of the substrate box 92, an opening 154 is formed in the substrate box 92. If the internal space of the substrate box 92 is opened by cutting the side cutting portion 151, the discovery can be performed relatively easily.

  Furthermore, in the configuration in which the box side cutting portion 151 is provided as described above, the function for satisfactorily opening the internal space of the substrate box 92 is performed by the box side cutting portion 151. Therefore, when the back side structure 101 and the front side structure 102 are fixed, it is not necessary to consider workability when the internal space of the substrate box 92 is opened.

  In other words, in the present embodiment, the breakage screw 143 is screwed to the back-side coupling portion 141 and the front-side coupling portion 142 so that the coupling between the both coupling portions 141 and 142 is difficult to be released. Yes. And the positive weak part for canceling | releasing fixation of both the structural bodies 101 and 102 by both the connection parts 141 and 142 like the conventional pachinko machine is not provided. In addition, an adhesive is applied to the boundary portion between the back-side component 101 and the front-side component 102, and both the components 101 and 102 are fixed over a wide range. Trying to insert it is difficult to do. Further, a seal seal 145 is attached so as to straddle the boundary portion between the back side structure 101 and the front side structure 102. As described above, the back-side structure 101 and the front-side structure 102 are firmly fixed, and accordingly, the act of illegally separating the back-side structure 101 and the front-side structure 102 is difficult to perform. It has become.

  Further, by cutting the box-side cutting portion 151 and removing the box-side removal region 153, the element mounting surface 97 of the main control board 91 is exposed, and the columnar connecting portion 132 of the intermediate structure 103 is further cut to cover the cover portion 133. As a result, the CPU chip 93 is exposed. That is, when accessing or removing the CPU chip 93, the destruction history of a plurality of members remains. For this reason, it is easier to confirm whether or not the CPU chip 93 has been removed. Thereby, fraudulent acts such as replacing the CPU chip 93 can be suitably suppressed.

  When the main control board 91 is inspected, there are a case where the operation is performed with the CPU chip 93 as it is, and a case where the operation is performed with the CPU chip 93 removed. As described above, the preparation for removing the CPU chip 93 is performed in two stages, and the inspection and the like can be performed while maintaining the restricted state of the CPU chip 93 by exposing the parts other than the CPU chip 93 in the first stage. it can. Particularly in the present embodiment, the main control board 91 is exposed stepwise, thereby suppressing unnecessary exposure of the CPU chip 93 and improving crime prevention.

  Conventional game machines often employ a configuration in which the entire main control board is exposed when the board box is opened. In such a configuration, if only the replacement of the CPU chip is performed after the main control board is exposed, it is assumed that it is difficult to determine the CPU chip itself by the difference in appearance. In the present embodiment, the configuration is such that the removal of the CPU chip 93 that is likely to be fraudulent among the elements mounted on the main control board 91 is regulated independently. As a result, it is possible to determine whether unauthorized replacement or the like has been performed by confirming the regulated state of the CPU chip instead of confirming the CPU chip when the seal of the main control board 91 is released. . This contributes to facilitation of confirmation work for fraud.

  The columnar connecting portion 132 of the intermediate structure 103 is configured to be easily cut as compared with other portions of the intermediate structure 103. Since the cover 133 can be separated by cutting the columnar connecting portion 132, the restriction state of the CPU chip 93 can be easily released. Particularly in the present embodiment, in order to remove the CPU chip 93, it is necessary to expose the CPU chip 93 itself by removing the cover portion 133 in addition to opening the substrate box 92 for exposing the element mounting surface 97. is there. As described above, by adopting a configuration in which the removal restriction of the CPU chip 93 is released through a plurality of stages, the crime prevention can be improved, but there is a concern that the workability of releasing the restriction at the time of inspection or the like is deteriorated. . However, in the present embodiment, the removal of the removal restriction is facilitated by cutting the columnar connecting portion 132, and deterioration of workability at the time of inspection of the CPU chip 93 is suppressed. In particular, as shown in FIG. 11 and the like, since the columnar coupling part 132 is exposed as the internal space of the substrate box 92 is released, the columnar coupling part 132 can be easily cut.

  Further, as shown in FIG. 11, a predetermined gap is provided between the columnar connecting portion 132 and the element mounting surface 97. For this reason, when performing a cutting operation from the front side of the element mounting surface 97, the inconvenience that the cutting edge of the tool contacts the element mounting surface 97 is suppressed. Thereby, the workability at the time of cutting is improved.

  Furthermore, unlike the box side cutting part 151 of the front side structure 102, the weak part of the intermediate structure 103 is less likely to limit the working direction at the time of cutting. Specifically, when cutting the box side cutting portion 151 of the front side structure 102, the work is performed by pressing a tool such as a cutter knife toward the element mounting surface 97 side. On the other hand, the columnar connecting portion 132 can be cut without applying a force to the element mounting surface 97 side with a tool such as a nipper, in addition to performing the cutting operation similar to the box-side cutting portion 151. Yes. In this way, the work can be performed without applying a force toward the element mounting surface 97 side, and therefore, the work can be performed without worrying about the force at the time of cutting. As a result, workability is further improved.

(Second Embodiment)
In the present embodiment, the configuration relating to the fixing of the intermediate structure in the board box of the main control device is different from that in the first embodiment. Therefore, the configuration of main controller 230 in the present embodiment will be described below. FIG. 16 is an exploded perspective view for explaining the configuration of main controller 230 in the present embodiment.

  The main control device 230 includes a main control board 231 and a board box 232 in the same manner as the main control apparatus 63 in the first embodiment. Similarly to the substrate box 92 in the first embodiment, the substrate box 232 includes a plurality of box components, a back-side component 233, a front-side component 234, an intermediate component 235, and a connector plate. 236. Further, similarly to the front side structure 102 in the first embodiment, the front side structure 234 is formed with a box-side cutting portion 237, and the main control board 231 has the first embodiment. Similar to the main control board 91 in the embodiment, a board-side cutting portion 238 is formed.

  However, in the main controller 230 in the present embodiment, the intermediate structural body 235 is fixed not only to the front-side structural body 234 but also to the back-side structural body 233. Specifically, a back fixing portion 242 having a screw hole and a front fixing portion 243 having a screw hole are integrally formed on the outer peripheral side of the frame-like portion 241 of the intermediate structure 235. Each of the back fixing portion 242 and the front fixing portion 243 is provided on each of the opposing frame portions of the frame-like portion 241, but a plurality of them may be provided.

  The screw holes of the back fixing portion 242 are opened toward the back side structural body 233, and the through holes 244 are formed in the back side structural body 233 at positions where the back fixing portion 242 and the substrate box 232 are aligned in the thickness direction. Is formed. In this case, the main control board 231 is interposed between the back fixing part 242 and the through hole 244, but the main control board 231 has a space between the back fixing part 242 and the through hole 244. A through hole 245 is formed so as not to block.

  The intermediate structure 235 is arranged so that the screw hole of the back fixing portion 242 and the through hole 244 of the back side structure 233 are located on the same axis with respect to the back side structure 233 in which the main control board 231 is integrated. The breaking screw 246 is screwed into the screw hole of the back fixing portion 242 from the back side structure 233 side. The broken screw 246 has a head portion separated after screwing. As a result, the intermediate structural body 235 is fixed to the back-side structural body 233, and basically the rear fixing portion 242 needs to be broken when releasing the fixing.

  The front fixing portion 243 has a screw hole opened toward the front side structural body 234, and the front side structural body 234 has a through hole 247 at a position aligned in the thickness direction of the front fixing portion 243 and the substrate box 232. Is formed. The front side structural body 234 in which the connector plate 236 is integrated is different from the back side structural body 233 in which the main control board 231 and the intermediate structural body 235 are integrated with the through holes 247 and the screw holes of the front fixing portion 243. Are arranged so as to be positioned on the same axis, and a breaking screw 248 is screwed into the screw hole of the front fixing portion 243 from the front side structure 234 side. The broken screw 248 has a separated head after screwing. As a result, the intermediate structure 235 is also fixed to the front-side structure 234, and basically the front fixing portion 243 needs to be destroyed when releasing this fixing.

  In addition, the back side structural body 233 and the front side structural body 234 are being fixed similarly to the board | substrate box 92 in the said 1st Embodiment.

  According to the present embodiment described in detail above, in addition to the effects in the first embodiment, it is possible to make it difficult to perform an act of illegally obtaining the genuine board box 232.

  That is, as an illegal act against the main control device 230, two main control devices 230 are prepared, taken out from one main control device 230 without destroying the front-side structure 234 and its accessories, and the other main control device 230 is taken out. It is assumed that the rear side structure 233 and its accessories are taken out from 230 without breaking. In this case, a genuine board box 232 can be obtained by combining the unit on the front-side structure 234 and the unit on the back-side structure 233 that are taken out without being destroyed. Then, when the main control device 230 of the pachinko machine 10 is replaced with the main control device 230 configured by accommodating the illegal CPU chip 249 or the like in the illegally obtained board box 232, the discovery is performed. It becomes difficult.

  On the other hand, according to the present embodiment, the intermediate structural body 235 is fixed to both the back-side structural body 233 and the front-side structural body 234, and when the fixation is released, the intermediate structural body 235 is destroyed. It is configured as required. Therefore, even if only the back-side structure 233 is destroyed and the unit on the front-side structure 234 side is taken out without being destroyed, the action cannot be performed because the back fixing portion 242 of the intermediate structure 235 is destroyed. Become. Further, even if only the front side structural body 234 is destroyed and the unit on the back side structural body 233 side is taken out without being destroyed, the act is impossible because the front fixing portion 243 of the intermediate structural body 235 is destroyed. Become. Therefore, it is possible to make it difficult to perform the above fraud.

  The fixing of the intermediate structure 235 to the back-side structure 233 and the fixing of the intermediate structure 235 to the front-side structure 234 are not limited to the breaking screws 246 and 248, and may be one-way screws. Moreover, you may use a locking tool instead of a screw. For example, when a locking hole is formed in the back fixing portion 242 and the front fixing portion 243, and a locking tool is inserted into the locking hole, the claw of the locking tool is inserted into the locking hole. It is good also as a structure which is hooked on a wall and cannot detach | leave the said locking tool. In a state where the locking tool is inserted into the back fixing portion 242, the intermediate structural body 235 and the back side structural body 233 are fixed, and the locking tool is inserted into the front fixing portion 243. In the state, the intermediate structure 235 and the front-side structure 234 are fixed. Even in this configuration, the intermediate structure 235 can be destroyed when the back-side structure 233 and the front-side structure 234 are taken out.

  That is, a back side structure, a front side structure, and an intermediate structure are provided, the intermediate structure is fixed to both the back side structure and the front side structure, and at least one of the back side structure and the front side structure is separated. May be destroyed, and the intermediate structure may be destroyed when the intermediate structure is separated from the back structure and the intermediate structure is separated from the front structure. Note that if only focusing on suppressing unauthorized acquisition of a genuine board box, the box-side cutting part may not be formed on the front side structure, and the board-side cutting part may be formed on the main control board. It does not have to be.

(Third embodiment)
In the present embodiment, a part of the configuration of the fixing means for the back side structure and the front side structure is different from that of the first embodiment. Therefore, the configuration of main controller 250 in the present embodiment will be described below. FIG. 17 is an exploded perspective view for explaining the configuration of main controller 250 in the present embodiment.

  The main control device 250 includes a main control board 251 and a board box 252 as in the case of the main control apparatus 63 in the first embodiment. Similarly to the substrate box 92 in the first embodiment, the substrate box 252 includes a plurality of box components, a back-side component 253, a front-side component 254, an intermediate component 255, and a connector plate. 256. Further, similarly to the front side structure 102 in the first embodiment, the front side structure 254 is formed with a box-side cutting portion 257 and the main control board 251 has the first embodiment. Similarly to the main control board 91 in the embodiment, a board side cutting portion 258 is formed.

  However, in the main controller 250 according to the present embodiment, the fixing of the back side structural body 253 and the front side structural body 254 at the long side portion is not performed by an adhesive, but a locking portion and a locking receiving portion. It is done by locking.

  Specifically, the back portion 253 is integrally formed with a locking portion 261. A plurality of locking portions 261 are provided, and the locking portions 261 are formed at equal intervals along the respective edges of the upper edge and the lower edge of the back side peripheral edge portion 262 of the back side structure 253. In this case, six locking portions 261 are formed on the top and the bottom, but the number is arbitrary as long as it is a plurality. All the locking portions 261 are formed to have the same shape and are all formed to the same size.

  Each locking portion 261 is formed with the back side peripheral edge 262 of the back side structure 253 as a base end, and is formed by being bent at an intermediate position so that the free end side extends toward one side edge of the back side structure 253. ing.

  A latch receiving portion 263 is integrally formed on the front side structure 254 so as to correspond to the latch portion 261. The locking receiving portion 263 is formed in one-to-one correspondence with the locking portion 261 at each of the upper edge and the lower edge of the front-side peripheral edge portion 264 of the front-side structure 254. Each latch receiving portion 263 has a space in which the latching portion 261 can enter from the back side of the front side structural body 254, and has a portion in which the latching portion 261 is latched in the space. .

  The locking of the locking portion 261 and the locking receiving portion 263 is performed by combining the back side structural body 253 and the front side structural body 254 so that the locking portion 261 is inserted into the locking receiving portion 263, and then the back side configuration. This is performed by sliding and moving at least one of the body 253 or the front side structure 254. In this state, the back-side structure 253 and the front-side structure 254 are fixed by connecting the connecting portions 265 and 266 respectively formed on the respective structures 253 and 254. In the main control device 250, the main control board 251 is fixed to the front side structural body 254 instead of the back side structural body 253 before the back side structural body 253 and the front side structural body 254 are combined. Is performed using a break screw.

  According to the present embodiment, the back-side structure 253 and the front-side structure 254 can be fixed satisfactorily without using an adhesive. The board box 252 is formed with a box-side cutting part 257 and the main control board 251 is formed with a board-side cutting part 258, so the first related to the opening of the internal space of the board box 252. The effect in embodiment can be show | played.

  In the present embodiment, since the main control board 251 is fixed to the front-side structure 254 using a breaking screw, the back-side structure 253 and the front-side structure 254 are released and separated from each other. Even if this is done, the CPU chip is not exposed. Therefore, in order to perform unauthorized acquisition and unauthorized replacement of the CPU chip in this configuration, it is necessary to destroy the main control board 251 and the like.

(Fourth embodiment)
In the present embodiment, the configuration related to fixing each component in the main control device and the configuration related to fixing the main control board are different from those in the first embodiment. That is, the configuration relating to the removal control of the main control board and the CPU chip is different from that of the first embodiment. Therefore, the configuration of main controller 300 in the present embodiment will be described below. FIG. 18 is an exploded perspective view for explaining the configuration of main controller 300 in the present embodiment.

  The main control device 300 includes a main control board 301 and a board box 302, similarly to the main control apparatus 63 in the first embodiment. The board box 302 includes a back-side structure 303, a front-side structure 304, and a connector plate 305 as a plurality of box structures, similarly to the board box 92 in the first embodiment. On the other hand, the intermediate structure is omitted. Further, the box side cutting part formed in the front side structure 102 is also omitted.

  In the main controller 300 in the present embodiment, the substrate box 302 is configured by fixing the components 303 and 304 to each other by the break screw 306, as in the first embodiment. More specifically, the front side coupling portion 307 of the front side configuration body 304 and the back side coupling portion 308 of the back side configuration body 303 are coupled in a non-removable state by the breaking screw 306. The broken screw 306 has a head portion separated after being screwed, and basically the components 303, 304, etc. need to be destroyed when the fixing of the components 303, 304 is released. As a result, the main control board 301 is isolated in the board box 302. Notches 309 and 310 constituting weak portions are formed around the root portions of the joints 307 and 308, and the cutouts 309 and 310 facilitate the separation of the joints 307 and 308. Has been. That is, when the coupling between the two structural bodies 303 and 304 by the breaking screw 306 is released, the periphery of the notches 309 and 310 is easily broken by bending the coupling parts 307 and 308. In this way, by facilitating the separation of the coupling portion, it contributes to the improvement of workability when releasing the restricted state.

  The main control board 301 is stored in the board box 302 as described above. In the present embodiment, as in the above-described embodiments, the element mounting surface 316 on which the CPU chip 315 and the like on the main control board 301 are mounted is arranged in a state where it faces the front-side structure 304 side. More specifically, the front side structural body 304 has a substantially box shape opened to the back side structural body 303, and the main control board 301 is disposed in a space defined by the front side structural body 304. The element mounting surface 316 of the main control board 301 is covered with the front side structure 304, and access to the element mounting surface 316 is restricted.

  Through holes 317 are formed at four corners of the main control board 301, and screw holes (not shown) are formed on the main control board 301 side of the front side structure 304 so as to be on the same axis as the through holes 317. ing. A break screw 319 inserted through the through hole 317 from the side opposite to the element mounting surface 316 (that is, the solder surface 318 side) of the main control board 301 is screwed into the screw hole. The broken screw 319 has a head portion separated after screwing. As a result, the main control board 301 is fixed to the front side structure 304, and the main control board 301 is basically required to be broken when releasing the fixing. Thereby, the element mounting surface 316 (specifically, the CPU chip 315) is isolated in the space defined by the front side structure 304 and the main control board 301, that is, in the state isolated in the front side structure 304. It has become.

  A board-side cutting part 320 extending in the vertical and horizontal directions is provided in the peripheral part of the through hole 317 in the main control board 301. More specifically, the substrate side cutting part 320 is disposed between the through hole 317 and the CPU chip 315 and the like. The substrate-side cutting part 320 includes a plurality of slits 321 formed so as to penetrate the main control substrate 301 in the thickness direction. By cutting off a part of the main control board 301 (specifically, a part of the main control board 301) along the board-side cutting part 320, a portion fixed by the breaking screw 319, the CPU chip 315, and the like were included. The site is divided. Thereby, the fixed state of the main control board 301, that is, the isolation state of the element mounting surface 316 is released.

  Here, the flow of work when removing the CPU chip 315 during inspection or the like will be described. First, the internal space formed by the two components 303 and 304 is opened. In each of the above-described embodiments, the main control board 301 can be accessed by removing the box-side removal region 153. In the present embodiment, on the other hand, the main control board 301 (specifically, the solder surface 318) is removed by releasing the connection between the structural bodies 303 and 304, specifically removing the connection portions 307 and 308. ) Can be accessed. In addition, by opening the internal spaces of both components 303 and 304, the substrate-side cutting part 320 of the main control board 301 is exposed. Here, by separating a part of the main control board 301 along the board side cutting part 320, the removal restriction state of the CPU chip 315 of the main control board 301 is released. Thereby, the main part of the main control board 301 including the CPU chip 315 can be removed. By removing the main part of the main control board 301, the CPU chip 315 and the like are exposed, and the inspection can be easily performed.

  According to the embodiment described above in detail, the same effects as those of the above-described embodiments can be obtained. That is, the CPU chip 315 can be removed by exposing the main control board 301 in the main controller 300 in a stepwise manner. When the main control board 301 is exposed stepwise, each is accompanied by destruction, so that traces of destruction remain at a plurality of portions. In this way, increasing the number of places where traces can be confirmed contributes to easier discovery of the opening facts. As a result, fraudulent discovery of the main control board 301 (particularly the CPU chip 315) can be facilitated, and as a result, it is difficult to perform fraudulent acts themselves.

(Fifth embodiment)
In the present embodiment, the structure of the fixing means for fixing the back side structure and the front side structure is different from that of the first embodiment. In other words, the configuration for regulating the exposure of the main control board is different from that of the first embodiment. Therefore, the configuration of main controller 330 in the present embodiment will be described below. FIG. 19 is a perspective view for explaining the configuration of main controller 330 in the present embodiment.

  The main control device 330 includes a main control board 331 and a board box 332 in the same manner as the main control apparatus 63 in the first embodiment. Similarly to the board box 92 in the first embodiment, the board box 332 includes a back side structure 333, a front side structure 334, an intermediate structure 335, and a connector plate 336 as a plurality of box structures. ing.

  In the main controller 330 in the present embodiment, the fixing of the back side structural body 333 and the front side structural body 334 at the long side portion is not performed by an adhesive, but by a sealing portion 337 (specifically by caulking or the like). It is connected so that it cannot be opened by a coupling part). As a result, the main control board 331 is stored inside the board box 332 in a state where exposure is restricted. A plurality of sealing portions 337 are provided on the long side portion of the substrate box 332 (five in this embodiment), and at least one of them is used to perform sealing processing (that is, processing for restricting exposure of the main control substrate 331). Is called.

  Any configuration can be applied to the sealing portion 337 as long as the back-side structural body 333 and the front-side structural body 334 are coupled together so that they cannot be opened. By inserting the pawl 339, the components 333 and 334 are coupled so as not to be opened. The sealing process by the sealing unit 337 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. That is, the sealing process is performed by inserting the locking claw 339 into at least one of the five sealing portions 337. When the substrate box 332 is opened such as when a failure occurs in the accommodated main control board 331 or when the main control board 331 is inspected, the sealing portion 337 into which the locking claw 339 is inserted and another sealing portion 337 are inserted. In addition, the connecting portion 340 with the main body portion of the substrate box 332 is broken (cut). The connecting part 340 is a weak part formed weaker than other parts of the substrate box 332, and specifically has a thin plate shape. By cutting the connecting portion 340, the respective components 333 and 334 of the substrate box 332 are separated, and the internal main control substrate 331 can be taken out. Thereafter, when the sealing process is performed again, the locking claw 339 is inserted into the long hole 338 of the other sealing portion 337. If the history of opening the substrate box 332 is left in the substrate box 332, it can be easily grasped that the opening has been performed by looking at the substrate box 332. As a result, when an unauthorized opening is performed, the opening fact can be found.

  In addition, the main control board 331 and the intermediate structural body 335 in the present embodiment are collectively fixed to one of the back-side structural body 333 and the front-side structural body 334. Specifically, it is fixed to the back side structure 333 with a breaking screw (not shown). The broken screw has a separated head after screwing. Since the sealing of the board box 332 is released and both the components 333 and 334 are separated, the element mounting surface 350 of the main control board 331 can be accessed. Specifically, it becomes possible to access a portion other than the CPU chip 352 covered by the cover portion 351 of the intermediate structure 335. When accessing the CPU chip 352 or removing the CPU chip 352 due to inspections or the like, each columnar connecting portion 353 of the intermediate structure 335 is placed at an arbitrary position (for example, a frame), as in the above embodiments. It is preferable to remove the cover portion 351 by cutting at the base of the shape portion side).

  According to the present embodiment, the sealing process can be performed a plurality of times during inspection and maintenance. Thereby, the reusability of the main controller 330 (specifically, the main control board 331) can be improved. That is, the main controller 330 is not required to be replaced by releasing the seal once, and can be used repeatedly. However, when the seal is released by an unauthorized person, there is a possibility that the CPU chip 352 is illegally replaced. If the sealing process is performed again after the CPU chip 352 has been replaced, it may be difficult to find fraud. More specifically, it is difficult to determine whether or not unauthorized opening has been performed unless the past opening history is grasped. In this embodiment, in order to replace the CPU chip 352, it is necessary to destroy the intermediate structure 335. Thus, when the intermediate structure 335 is destroyed, it can be easily recognized that unauthorized opening may have been performed by confirming the existence of the destruction fact. Therefore, compared with the case where the sealing part 337 is confirmed, discovery of unauthorized opening is facilitated.

  Further, in the present embodiment, by releasing the sealing of the substrate box 332, the element mounting surface 350 is exposed, thereby facilitating inspection and the like, and the CPU chip 352 that is likely to be fraudulent. Fragmentation is made more difficult by removing the seals from the seals. That is, both improvement in maintainability and improvement in fraud suppression effect can be expected.

However, in this structure, the box side cutting part 284 is formed in a double manner. Of the double box side cutting portions 284, the inner one is formed in the surface constituting portion 283 so as to partition the CPU chip of the main control board and a region facing the periphery thereof. On the other hand, the outer one of the double box side cutting portions 284 is formed so as to partition the outer side of the surface constituting portion 283 from the region facing the excisable region of the main control board. According to this configuration, one of the double box-side cutting portions 284 may be cut according to the purpose of inspection. In particular, the length that needs to be cut when inspecting only the CPU chip can be made shorter than that of the first embodiment.

  (15) In the fourth embodiment, the main control board 310 is arranged so that the element mounting surface 316 of the main control board 310 faces the front-side component 304 side. It is also possible to arrange so that 316 faces the back side structure 303 side. In such a case, by fixing the main control board 310 to the back side structure 303, it is possible to avoid exposure of the element mounting surface 316 (specifically, the CPU chip 315) when the internal space of the board box 302 is opened. Is possible. However, when the element mounting surface 316 of the main control board 310 is directed toward the back side component 303 in this way, it is necessary to open the back pack unit 15 in order to confirm the element mounting surface 316 side during maintenance or the like. Occurs. Furthermore, it is necessary to rotate the main controller 300 so that its back side can be visually recognized. In general, it is considered that the device mounting surface 316 is more likely to be a fraud target than the solder surface 318. Therefore, preferably, as shown in the fourth embodiment, the element mounting surface 316 may be disposed so as to face the front-side structure 304 side.

  (16) In each of the first to third embodiments, as shown in FIG. 8 and the like, the intermediate structure 103 has a frame shape, but the intermediate structure is opened to the main control board 91 side. It is also possible to form. A part of the element mounting surface 97 including the CPU chip 93 may be covered with the box-shaped intermediate structure. In such a case, similarly to the front side structure 102, the intermediate structure is provided with a cutting portion as a fragile portion, and the CPU chip 93 or the like can be removed by cutting a part of the intermediate structure along the cutting portion. The configuration may be as follows. However, when the intermediate structure is box-shaped, it is assumed that the heat generated in the main control board 91 is likely to be trapped. Therefore, it is desirable to set a large number of ventilation holes to improve heat dissipation.

  (17) In each of the first to third and fifth embodiments, the entire columnar connecting portion 132 of the intermediate structure 103 is configured to have the same strength. You may set so that intensity | strength may become weak compared with the intensity | strength of another site | part. For example, a partial reduction in strength may be realized by providing a notch or the like in a part of the columnar connecting portion.

  (18) In each of the first to third embodiments, the main control board 91 is provided with the board-side cutting portion 161, and the main control board 91 is cut to remove the main part of the main control board 91. Although it has been made possible, this may be changed as follows. That is, it is good also as a structure which can remove a main control board by destroying the attachment object side (for example, back side structure etc.) among the main control board and its attachment object. In such a case, it is preferable to provide a weak portion around the fixed portion of the main control board on the attachment target side.

  (19) In each of the above embodiments, the front-side structure 102 and the back-side structure 101 are assembled in the direction orthogonal to the element mounting surface 97 of the main control board 91, but the main control is performed. The assembly may be performed by sliding the front side structure and the back side structure in a direction parallel to the element mounting surface of the substrate. For example, it may be slid in the longitudinal direction of the main control board. In particular, in the configuration having the intermediate structure, the element mounting surface is easily protected by the intermediate structure. For this reason, at the time of slide mounting, the inconvenience that each element hits the front-side structure or the back-side structure and is damaged can be suitably suppressed.

  (20) In each of the first to third embodiments, as shown in FIG. 10A and the like, the peripheral portion of the box-side removal region 153 and the intermediate structure in the direction orthogonal to the element mounting surface 97 103, the box-side removal region 153 is prevented from falling into the substrate box 92 when the box-side removal region 153 is removed. This is as follows. It may be changed. That is, the peripheral portion of the box-side removal region 153 and the frame-like portion 131 of the intermediate structure 103 do not have to be overlapped. In this case, when the box side removal region 153 is removed, the box side removal region 153 may fall into the substrate box 92. Therefore, the cover 133 may be configured to prevent the box-side removal region 153 from collapsing. Specific examples are shown below.

  As shown in FIG. 8 and the like, the CPU chip 93 accommodated in the cover portion 133 has the largest protrusion amount from the element mounting surface 97. The cover portion 133 that accommodates the CPU chip 93 also protrudes greatly from the element mounting surface 97. When the box side removal region 153 is removed, the box side removal region 153 may fall toward the element mounting surface 97 side. In such a case, a load may be generated on each IC chip 94 and the like due to the box side removal region 153 hitting the element mounting surface 97. However, since the cover part 133 protrudes greatly from the element mounting surface 97 as described above, the box-side removal region 153 hits the cover part 133 and does not easily hit other IC chips 94 or the like. As described above, the protection function of the element mounting surface 97 can be given to the cover portion 133.

  (21) In the above embodiments, the CPU chip 93 and the like are stored in the closed space formed by the cover 133 and the like in order to restrict the removal and exposure of the CPU chip 93 and the like. It is good also as a structure which changes and controls only removal of CPU chip 93 grade | etc.,. For example, you may provide the movement control part which suppresses the movement to the removal / removal direction of CPU chip 93 instead of a cover part.

  (22) In each of the above embodiments, the main control board 91 is exposed by cutting or destroying a part of the board box 92 (specifically, the box-side cutting part 151). It may be changed as follows. That is, the main control board 91 is sealed by connecting the constituent members 101 and 102 constituting the board box 92 with a sealing seal, and the main control board 91 is exposed by removing the sealing seal. It is good also as a structure. The seal seal, like the seal seal 145 shown in the above embodiment, is such that when the seal seal is peeled off, the base material of the seal is destroyed and traces of the destruction remain. In order to make the main control board 91 exposed, the sealing seal is first removed. As a result, the main control board 91 can be exposed. Thereafter, by separating the components 101 and 102, the main control board 91 is exposed.

  (22) The configuration applied to the board box of the main control device in each of the above embodiments may be 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. Good.

  (23) 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. Instead, a single outer storage unit is provided. The present invention may be applied to a pachinko machine. Further, by providing the power failure monitoring device separately from the main control device 63, the main control board 91 may be configured to have only the function of the main control circuit 202.

  (24) Other types of pachinko machines different from the above-described embodiments, such as pachinko machines in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or games in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a ball enters, a pachinko machine equipped with another accessory, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. If a specific symbol or a combination of specific symbols is established on the effective line visible from the display window after the reel has stopped after a predetermined time has passed, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.

  The slot machine includes a box-shaped casing opened forward and a front door that closes the opening of the casing, and a control board device is accommodated in the casing. In this case, the box-side cutting portion is cut by arranging the control board device so that the surface on which the box-side cutting portion is formed in the substrate box of the control board device is visible when the front door is opened. It can be easily confirmed whether or not it is done.

  In addition, the gaming machine main body that is supported by the outer frame so as to be openable and closable is provided with a storage unit and a capture device, and the start lever is operated after a predetermined number of game balls stored in the storage unit are captured by the capture device. Thus, the present invention can also be applied to a gaming machine in which a pachinko machine and a slot machine are fused, which starts rotating the reel.
