  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 plurality of types of gaming machines, pachinko gaming machines, slot machines, etc. are known. These gaming machines have an electronic component such as a CPU or a ROM in which a control program related to gaming is stored. A series of games are controlled by the control board mounted on the control board, and in recent years, there are CPUs and ROMs that are mounted on the control board as a single chip. In the gaming machine of the above, for the purpose of obtaining illegal profits, the ROM in the control board (or the chip if the CPU or ROM is made into one chip) is exchanged to change the game contents, etc. Many fraudulent acts have been reported, and various types of fraud countermeasures have been studied, for example, coupling for connecting a plurality of box structures constituting a board box to each other. A structure having a structure (so-called caulking structure) is known (see, for example, Patent Document 1.) The coupling structure is configured to require destruction when the coupling is released. When a box is opened, it is possible to leave an opening history due to its destruction, and if a board box is opened illegally, it can be detected. Therefore, in order to facilitate the opening operation of the substrate box at the time of this inspection, the joint structure is actively provided with a weak portion, and the weak portion is broken (cut). As a result of the background art, “the connection by the connection structure is released and the substrate box can be opened.” Even if it is a board device, it is possible that fraudulent acts are still being carried out, for example, it is possible to make the fragile part inconspicuous, and it is easy to detect that the board box has been illegally opened. The invention “There is a possibility that it cannot be done” has been made with a problem to be solved.

Means 1. A control board (main control board 91, etc.) for controlling the game,
An internal space is formed, and the internal space includes a substrate box (such as the substrate box 92) in which the control board is accommodated.
The board box is configured by combining a plurality of box structures (back side structure 101, front side structure 102, etc.) and connecting these box structures to each other by a coupling means (breaking screw 180, etc.)
Each box structure has a partition wall portion (back side peripheral wall portion 118, front side peripheral wall portion 122, etc.) having a substantially constant thickness that partitions the internal space and the external space of the substrate box.
Each of the box structural bodies is coupled to each other by fixing the partition wall portions by the coupling means.

  According to the means 1, each box structure has a partition wall section that divides the inside and outside of the substrate box, and the partition box section is coupled by the coupling means to form a substrate box. In order to release the coupling state by the coupling means, it is necessary to destroy at least one of the coupling means itself or the coupling portion of the partition wall portion fixed by the coupling means.

  In general, the following configurations are often used for coupling the box components. That is, the partition wall portion is formed with a coupling portion or the like protruding outward from itself, and these coupling portions are often fixed by a coupling means. Thereby, the improvement of the visibility of a joint part, the improvement of workability | operativity at the time of joining, etc. are achieved. However, when the part (joint part) which protruded from the partition wall part by the coupling | bonding means is being fixed as mentioned above, these joint parts may be cut | disconnected along the wall surface of a partition wall part. In this way, when the coupling portion is removed along the wall surface, it may be possible to release the coupled state while making the trace of destruction less noticeable. Furthermore, when the cut joint is returned to its original position by a fixing means such as adhesion, it may be difficult to find the trace. For example, there is a concern that the traces that are generated along with the release of the combined state are formed along the wall surface, so that the traces are easily confused with respect to the projecting portion and the correlation line of the wall surface.

  In this respect, in this means, the coupling is performed at the partition wall portion formed to have a substantially constant thickness, and the coupling is not performed at the protruding portion as described above. That is, it is assumed that the partition wall portion itself is easily destroyed rather than the protruding portion or the like with the release of the coupled state. If the partition wall is destroyed and traces of the damage remain, it is easy to confirm the fact that the control board may have been accessed, that is, the fact that the board box has been opened. can do. More specifically, an opening, a dent, etc. will be formed in a board | substrate box with destruction of a partition wall part. For this reason, if the inner space of the board box is opened by destroying the peripheral part of the coupling means (that is, the partition wall) for the purpose of cheating on the control board or the like, it is relatively difficult to find the trace. It can be done easily. Even if a part of the partition wall is removed and then returned to the original position by adhesion or the like, it is difficult to cause inconvenience that it is difficult to confirm the trace. More specifically, the remaining trace is likely to be three-dimensional with respect to the partition wall (that is, formed on a scale that can be visually recognized in the thickness direction of the partition wall), and the trace is formed on the partition wall. The inconvenience of being difficult to visually recognize due to a correlation line between the projected portion and the wall surface is less likely to occur. Thereby, it can suppress suitably that the destruction trace which remains in a partition wall part is concealed.

  Note that “the partition walls are fixed by the coupling means” means that separation between the partition walls is suppressed, and includes the following concept. That is, a state in which the defining unit (for example, the guide unit 318 and the sliding unit 319) that defines relative movement between the partition walls when the box components are combined in a predetermined direction and the box components are combined. And a restricting means (for example, a fixing tool 330) for restricting relative movement of the partition wall portion in the predetermined direction by being hooked at, and disabling separation of the partition wall portions by the defining portion and the restricting means. including.

  Further, the “substantially constant wall thickness” shown in the present means includes a wall having a constant wall thickness formed with protrusions such as ribs for the purpose of reinforcement. However, even in the configuration having such a protrusion or the like, the box components are coupled to each other only at the partition wall portion having a constant thickness.

Mean 2. The partition wall portion is formed so as to be substantially parallel to the planar inner wall surface (inner wall surface 118a, 122a) defining the inner space of the substrate box, and the inner wall surface, An outer wall surface (outer wall surface 118b, 122b) that defines a boundary with the outer region of the substrate box,
The gaming machine according to claim 1, wherein the coupling means is provided closer to the inner space than the outer wall surface.

  According to the means 2, the coupling means is provided on the inner side of the outer wall surface in the partition wall portion. Thus, by arranging the coupling means inside the outer wall surface, it is possible to make it difficult to access (physical contact) to the coupling means itself. When it is difficult to access the coupling means, it is assumed that the peripheral portion of the coupling means in the partition wall portion is likely to be broken in order to release the coupled state. Even if the coupling means is removed by destroying (cutting, etc.) a part of the partition wall as described above, even if the coupled state of the box structure is released, for example, an illegal Even when access or the like is made, if the peripheral portion of the coupling means is destroyed, the trace is likely to remain largely on the partition wall. Therefore, it can contribute to facilitating the discovery of the destruction traces remaining on the partition wall, and an improvement in crime prevention can be expected.

  Means 3. The gaming machine according to claim 2, wherein the outer wall surface of each box component is located on the same plane.

  According to the means 3, since the outer wall surface of each component (specifically, each partition wall portion) coupled by the coupling means is located on the same plane, the boundary portion between both the partition wall portions (that is, the box configuration) The occurrence of a step between the outer wall surfaces at the boundary portion between the bodies, specifically, the generation of a step in the thickness direction of the partition wall portion is suppressed. If the outer wall surfaces of the partition walls have a stepped shape, there is a concern that the stepped portion is cut along the outer wall surface. In such a case, it may be difficult to confirm the trace of the cutting. In general, a coupling means provided across a boundary portion between the partition wall portions is easily used for coupling between the partition wall portions. As described above, when the partition wall portion is cut using the step at the boundary portion between the two partition wall portions, the connecting means is accessed while ensuring that the trace is not conspicuous. There is a possibility that the combined state of the constructs is released. Thus, it becomes difficult to find the illegal release of the combined state by making the traces less conspicuous.

  In this respect, in this means, since the occurrence of the step at the boundary part between the two partition walls is suppressed as described above, the destructive action around the combined part using the step part of the boundary part between the partition walls (details) Can be suitably avoided. Therefore, concealment of the destruction trace can be suppressed, and a practically preferable configuration can be realized.

  Means 4. The gaming machine according to means 2 or 3, wherein the outer wall surface of each box structure forms a continuous surface across a boundary portion between the two partition wall portions.

  According to the means 4, the same effect as the means 3 can be obtained. That is, since the outer wall surface of each partition wall part joined by the coupling means forms a continuous surface across the contact part of both partition wall parts, the outer wall surfaces at the boundary part between both partition wall parts Generation of a step (a step in the thickness direction) is suppressed. For this reason, the destruction action (specifically cutting action) around a joint part using the level | step-difference part of the boundary part between division walls can be avoided suitably. Therefore, concealment of the destruction trace can be suppressed, and a practically preferable configuration can be realized.

  In addition, “continuous surface” includes a surface that is not strictly a single surface, but that appears to be continuous at a glance with little bending, and a surface that appears to be continuous without a step. . For example, one outer wall surface is configured with a flat surface, and the other outer wall surface is configured with a curved surface that bends along the former, or both outer wall surfaces have a minute angle such as a pull angle in a mold (for example, about 10 °) ) As an angle difference between the outer wall surfaces.

  Means 5. The gaming machine according to means 3 or 4, wherein a shielding part (shielding part 124) that covers the boundary part from the outer wall surface side is integrally formed on the partition wall part.

  According to the means 5, the boundary portion between the partition wall portions is closed from the outer wall surface side, that is, from the outside of the substrate box, by the shielding portion integrally formed on the partition wall portion. By this shielding part, the inconvenience that the coupling means is accessed through the boundary part can be suitably suppressed.

  In addition, as shown in the means 3 and means 4, since the occurrence of a step between the outer wall surfaces (step in the thickness direction) is suppressed, even if the shielding part is cut along the outer wall surface, As a result, the coupling means is not accessed or the coupling state by the coupling means is not affected while making the trace of cutting difficult to understand. That is, by providing a shielding part, it is difficult to cause inconvenience that an illegal act is performed using the shielding part as a foothold. Therefore, it can contribute to the further improvement of crime prevention.

  Means 6. Means 2 including a housing portion (through hole 182, screw hole 183, etc.) provided in a region sandwiched between the inner wall surface and the outer wall surface of the partition wall portion and housing the coupling means. A gaming machine according to any one of the means 5 to 5.

  According to the means 5, the coupling means is accommodated in the accommodating portion provided in the region sandwiched between the inner wall surface and the outer wall surface. Thus, by accommodating the coupling means in the partition wall, it is difficult to access the coupling means from the outside of the substrate box. As a result, it is possible to make it difficult to cause inconvenience that only the coupling means is illegally removed in the release of the coupled state, and it is possible to realize a configuration in which the destruction traces of the partition wall portions are easily left.

  Mean 7 A closed space isolated from the outer wall surface is formed in the partition wall portion in a state where the box structural bodies are coupled to each other, and the coupling means is accommodated in the closed space. A gaming machine according to any one of means 2 to means 5 characterized by the above.

  According to the means 7, the coupling means is accommodated in a closed space formed in the partition wall portion. For this reason, in a state in which both components are coupled, it is impossible to access the coupling means from the outside of the substrate box. Thus, in order to remove the coupling means by hindering access to the coupling means itself, it is necessary to destroy the peripheral portion of the coupling means, that is, the partition wall portion. When the coupling means is configured to be accompanied by destruction of the partition wall portion, it is difficult to conceal the traces, and the deterrent effect can be enhanced.

  Means 8. A recess (mounting hole 331, round hole 336) formed on at least one of the two partition walls and opened to the boundary portion between the partition walls is closed by the other partition wall. 8. A gaming machine according to means 7, wherein a closed space is formed.

  In order to form the closed space shown in the means 7, as shown in the present means, the concave portion formed in at least one of the partition wall portions may be closed by the other partition wall portion. Thus, isolation | separation of a coupling | bonding means can be easily implement | achieved by setting it as the structure by which both structures are combined and a closed space is formed.

Means 9. A control board (main control board 91, etc.) for controlling the game,
An internal space is formed, and the internal space includes a substrate box (such as the substrate box 92) in which the control board is accommodated.
The board box is configured by combining a plurality of box structures (back side structure 101, front side structure 102, etc.) and connecting these box structures to each other by a coupling means (breaking screw 180, etc.)
Each box structure has, as a basic structure, a partition wall portion (back side peripheral wall portion 118, front side peripheral wall portion 122, etc.) having a substantially constant thickness that partitions the internal space and the external space of the substrate box.
Each of the box structural bodies is coupled to each other by fixing the partition wall portions by the coupling means.

  According to the means 9, the same effect as the means 1 can be obtained. Specifically, each box structure has a partition wall portion that divides the inside and outside of the substrate box as a basic structure, and the partition box portion is coupled by a coupling means to form a substrate box. Yes. When the combined state is released by breaking the partition wall portion, an opening, a dent, or the like is formed in the substrate box as the partition wall portion is broken. For this reason, if the inner space of the board box is opened by destroying the peripheral part of the coupling means, that is, the partition wall part for the purpose of cheating on the control board or the like, the discovery can be performed relatively easily. it can. Moreover, it can also suppress suitably that the destruction trace which remains in a division wall part is concealed.

  Note that “having a partition wall portion having a substantially constant thickness as a basic structure” means that ribs or the like for reinforcement are added to the partition wall portion of the box structure (for example, integrally molded). Even if the plate thickness is partially changed (increased) by the protrusions, etc., a certain thickness excluding the portion where the plate thickness is changed by the protrusions, etc. It is shown that the partition wall portion is constituted by the base portion in which is secured, and each box component has these partition wall portions.

Means 10. A control board (main control board 91, etc.) for controlling the game,
An internal space is formed, and the internal space includes a substrate box (such as the substrate box 92) in which the control board is accommodated.
The board box is configured by combining a plurality of box structures (back side structure 101, front side structure 102, etc.) and connecting these box structures to each other by a coupling means (breaking screw 180, etc.)
Each of the box structural bodies has wall portions (back side peripheral wall portion 118, front side peripheral wall portion 122, etc.) that contact each other in a state in which the box structural bodies are combined,
The wall portion is provided with an inner wall surface (inner wall surfaces 118a, 122a) defining an inner space of the substrate box and a predetermined distance from the inner wall surface, and the substrate box and an outer region of the substrate box An outer wall surface (outer wall surface 118b, 122b) that defines a boundary with
In each of the wall portions, the portions constituting the inside and outside of the substrate box by the inner wall surface and the outer wall surface are fixed to each other by the coupling means, whereby the box structural bodies are coupled to each other. To play.

  According to the means 10, the same effect as that shown in the means 1 can be obtained. Specifically, the portions that define the inside and outside of the substrate box by the inner wall surface and the outer wall surface in the wall portion are joined together. Such a connection between the wall portions is different from the case where the connection is performed at the projecting portion formed on the wall portion as described above, and when the connection state is released, the connection means itself is destroyed or the connection portion in the wall portion, etc. Will be accompanied by destruction. In particular, if the wall is destroyed and traces of the destruction remain, confirm the fact that the control board may have been accessed, i.e. the fact that the board box has been opened. It can be made easier. More specifically, since an opening or the like is formed in the substrate box with the destruction of the wall portion, if the coupled state is canceled for the purpose of performing fraud on the control substrate or the like, Traces of fraud can be detected relatively easily. Moreover, when traces, such as an opening, remain in a wall part, it is thought that it is difficult to conceal such traces. In this way, it becomes difficult to conceal the traces, so that it is possible to expect an improvement in fraud suppression effect.

Means 11. On the control board, an element (CPU chip 93 or the like) storing a game control program is mounted,
Opposite to the element mounting surface in the substrate box, provided to divide the defining portion (front side wall portion 121) defining the internal space of the substrate box into a plurality of regions, and the mutual coupling state in the box structure Is provided with a box-side cutting part (box-side cutting part 151 or the like) formed so as to be easily cut so as to open the internal space more easily than when releasing the internal space.
When the box-side cutting portion is cut and a part of the defining portion (box-side removal region 153) is removed from a position defining the internal space, at least in the removal of the element or the control board 11. The gaming machine according to any one of means 1 to 10, wherein an opening (opening 154 or the like) that allows removal of a region where the element is mounted is formed in the substrate box.

  According to the means 11, the box side cut portion is formed in the substrate box, and the box side cut portion is cut to remove a partial region of the defining portion from the position defining the internal space. An opening is formed in the substrate box to allow removal of the element storing the game control program. And since the box side cutting part is formed so as to be cut more easily than the case of releasing the mutual coupling state of the box structures by the coupling means, when the above elements are taken out from the board box at the game hall and carefully inspected. Can perform the operation relatively easily.

  In addition, when the box-side cutting part is cut to open the internal space of the board box, an opening is formed in the board box, so that the box-side cutting part is cut for the purpose of cheating on the elements etc. If the internal space of the substrate box is open, the discovery can be performed relatively easily.

  Furthermore, in the configuration in which the box side cutting portion is provided as described above, a function for satisfactorily opening the internal space of the substrate box is fulfilled by the box side cutting portion. When joining the bodies, there is no need to consider workability when opening the internal space of the substrate box. Therefore, it is possible to firmly perform the mutual coupling of the box structures by the coupling means.

  In addition, the “partition wall portion” and the “defining portion” shown in the means 1 to 10 may indicate the same object, or may indicate different objects. In particular, if the two are different objects, the following excellent effects can be obtained. Specifically, in the case of a configuration in which the partition wall portion of the box structure is fixed, the partition wall portion is provided by providing a box-side cutting portion as a trace means for leaving a destruction trace in a portion (regulation portion) other than the partition wall portion. And other roles can be clearly divided in other parts. As a result, even if the thickness of the partition wall is increased to improve the coupling strength by the coupling means, the work of opening the substrate box at the time of maintenance or confirmation can be facilitated. That is, it is possible to secure a workability at the time of confirmation or the like while improving crime prevention, and to realize a practically preferable configuration. In particular, since it is not necessary to easily break the partition wall portion, it is possible to contribute to an improvement in the degree of freedom of arrangement of the coupling means.

  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.

  "Release the mutual coupling state" means that the coupling state is canceled by destroying the coupling means itself, and the coupling state is canceled by removing part of the partition wall together with the coupling means. Indicates to do.

  Incidentally, the “box-side cutting portion formed so as to be easily cut” can be easily realized by applying the following configuration, for example. “A plurality of through-holes (through-holes 152) penetrating into and out of the substrate box are arranged on a predetermined line, and the through-holes have a long hole shape, and the longitudinal direction of each through-hole is the predetermined line. The configuration in which the cutting section is arranged is formed by arranging a plurality of through holes (through holes 152) penetrating in and out of the substrate box on a predetermined line. A configuration in which the distance dimension between the through holes arranged in parallel to each other is set smaller than the length dimension of the through holes in the juxtaposed direction may be applied.

  Means 12. 12. The gaming machine according to claim 11, wherein the box side cutting part is formed so as to partition an area including a part facing the element in the defining part with respect to a surrounding area.

  According to the means 12, it is possible to expose the region where the element is mounted on the control board by cutting the box side cutting part. Therefore, workability in the case of inspecting elements can be improved.

  Note that the “part facing the element” has not only a structure in which no member is interposed between the part and the element but also a structure in which a predetermined member is interposed between the part and the element. Is also included. Examples of the predetermined member include a cover portion that covers the element in the internal space of the substrate box. The same applies to the following.

  Means 13. The box-side cutting part is formed such that an opening formed in the substrate box is cut to a size that makes it impossible to take out the control board by cutting the box-side cutting part. 11. A gaming machine according to 11 or means 12.

  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 in which the configuration of the above means 1 is provided and the box side cutting portion is provided in the substrate box, the control board is removed through the opening formed in the substrate box by cutting the box side cutting portion. An act to be removed is assumed. On the other hand, according to this means, even if the box side cutting part is cut, it becomes difficult to remove the control board, and it is possible to make the illegal act difficult.

  The control board may be fixed by a fixing tool or the like in the board box. In such a case, it is difficult to remove the control board from the opening even if the fixing by the fixture is released. Thereby, it can contribute to the improvement of crime prevention.

  Below, the specific example of the gaming machine which can implement | achieve this means is shown.

  The control board includes a regulation unit that regulates removal of the control board from the board box by contacting the regulation part in which the opening is formed when the control board moves to the opening side. The gaming machine according to means 11 or 12, characterized in that

In other words, the main control board 91 has one plate surface as the element mounting surface 97 and the other plate surface as the solder surface 98. The solder surface 98 is a surface provided with soldering portions of various elements mounted on the element mounting surface 97, but a circuit pattern may be formed on the solder surface 98.

  Here, the CPU chip 93 is disposed in the vicinity of the center of the element mounting surface 97, and is further provided upright from the element mounting surface 97. Further, the CPU chip 93 is not soldered to the main control board 91 as described above, and the connection terminals of the CPU chip 93 are inserted into the main control board 91. That is, the CPU chip 93 is mounted on the main control board 91 in a state where it can be inserted and removed. However, the CPU chip 93 may be soldered to the main control board 91.

  The board box 92 includes a back side structure (box base or back case body) 101, a front side structure (box cover or front case body) 102, and an intermediate structure (intermediate frame or intermediate case) as a plurality of box structures. Body) 103 and a connector plate (middle plate) 104. The back-side structure 101, the front-side structure 102, the intermediate structure 103, and the connector plate 104 visually recognize the element mounting surface 97 and the solder surface 98 of the main control board 91 housed in the board box 92 from the outside of the board box 92. It is made of a material having transparency as much as possible. Specifically, it is formed of a colorless and transparent polycarbonate resin, but is not limited thereto, and may be an acrylic resin or the like, and may be colored and transparent.

  As shown in FIGS. 8 and 9, the back-side structure 101 includes a flat portion 111 having a substantially long plate shape, like the main control board 91. The main control board 91 is disposed such that the solder surface 98 faces the flat portion 111. The flat portion 111 has a substantially rectangular shape whose longitudinal direction is the same as the longitudinal direction of the main control board 91, and its outer shape is larger than the outer shape of the main control board 91. Further, a partition frame portion 113 that partitions the plate surface into a quadrangular shape is integrally formed on the side of the plane portion 111 facing the main control board 91. The partition frame portion 113 protrudes from the flat surface portion 111 toward the main control board 91 side.

  As shown in FIG. 8, a plurality of bosses 114, 115, and 116 are integrally formed on the plane portion 111 on the inside and outside of the area partitioned by the partition frame portion 113. Each has a screw hole. Of these bosses 114 to 116, the bosses 114 formed at the four corners of the region partitioned by the partition frame portion 113 are used to fix the main control board 91 to the back side structural body 101. The other bosses 115 in the region partitioned by are used for temporarily fixing the main control board 91, and the bosses 116 formed outside the region partitioned by the partition frame 113 are front side configurations. It is used for temporarily fixing the body 102. In the following description, the first boss 114 is the substrate main fixing boss (substrate main fixing portion) 114, the next boss 115 is the substrate temporary fixing boss (substrate temporary fixing portion) 115, and the last boss 116 is the box temporary fixing. It is also called a fixing boss (box temporary fixing portion) 116.

  The main control board 91 is fixed to the back side structure 101 by being screwed to the board main fixing boss 114. The peripheral edge of the main control board 91 overlaps with the partition frame portion 113 of the back-side structure 101, and the solder surface 98 of the main control board 91 faces the area partitioned by the partition frame section 113 in the flat portion 111. . In this case, a closed space may be formed between the main control board 91 and the flat surface portion 111 by bringing the peripheral edge portion of the main control board 91 into contact with the partition frame portion 113. You may make it provide a clearance over the periphery.

  The main control board 91 is screwed to the board fixing boss 114 by screwing a break screw 117 from the element mounting surface 97 side of the main control board 91. Here, the breaking screw 117 is one in which the strength of the connecting portion between the head on which the tip can be inserted into a tool such as a driver and the side on which the screw groove is formed is set low, and can be tightened further. When a predetermined force is further applied to the head by the tool at a position where it cannot be performed, the connecting portion is cut and the head is separated. That is, the breaking screw 117 cannot be rotated in the loosening direction using the tool after screwing. If it is possible to prevent the main control board 91 and the main board fixing boss 114 from being loosened after screwing, the main control board 91 and the main board fixing boss 114 are connected. The fixture (coupling means) is not limited to the breaking screw 117 and may be a well-known one-way screw. The breaking screw 117 screwed to the board main fixing boss 114 has a head portion separated after screwing.

  The board temporary fixing boss 115 and the box temporary fixing boss 116 are respectively used after the board box 92 is opened in the inspection of the main control board 91 in the game hall. This will be described in detail later, and will not be described here.

  In addition, a rear side peripheral wall portion 118 that stands on the main control board 91 side and surrounds the main control board 91 is integrally formed on the entire outer peripheral edge of the flat portion 111. The back side peripheral wall portion 118 is configured by connecting four plate-like portions corresponding to the respective edge portions of the flat portion 111, and each of the plate-like portions has a substantially constant thickness. The main control board 91 is accommodated in a space defined by the flat surface portion 111 and the back side peripheral wall portion 118. That is, the back side structure 101 has a substantially box shape opened to one side, and the main control board 91 is accommodated in the back side structure 101.

  The front side structure 102 in which the intermediate structure 103 and the connector plate 104 are integrated is fixed to the back side structure 101 in which the main control board 91 is integrated as described above.

  Specifically, as shown in FIGS. 8 and 9, the front side structure 102 has a front side wall portion 121 that faces the element mounting surface 97 of the main control board 91. That is, the main control board 91 is sandwiched between the flat surface portion 111 of the back side structure 101 and the front side wall portion 121 of the front side structure 102. The front side wall portion 121 has a substantially rectangular shape when viewed from the front side of the main control board 91, and the outer shape thereof is formed to be substantially the same as the outer shape of the plane portion 111. A front side peripheral wall portion 122 standing on the main control board 91 side is integrally formed on the entire outer peripheral edge of the front side wall portion 121. Like the back side peripheral wall part 118, these front side peripheral wall parts 122 are configured by connecting four plate-like parts corresponding to the respective edge parts of the front side wall part 121, and each of these plate-like parts has a substantially constant thickness. Has a thickness. By these front side wall part 121 and front side peripheral wall part 122, the front side structure 102 is made into the structure which makes | forms the substantially box shape open | released by the main control board 91 side.

  The front side peripheral wall portion 122 is disposed so as to be continuous with the back side peripheral wall portion 118. More specifically, the back-side peripheral wall portion 118 and the front-side peripheral wall portion 122 have a predetermined thickness (in the present embodiment, both thicknesses are the same), and in a state in which both the constituent members 101 and 102 are fixed. The end surfaces 119 and 123 of the peripheral wall portions 118 and 122 are in surface contact with each other. That is, the contact portion between these end surfaces 119 and 123 defines the boundary between the two structural members 101 and 102 (specifically, the two peripheral wall portions 118 and 122). Inner wall surfaces 118a and 122a of both peripheral wall portions 118 and 122 are connected with a boundary therebetween, and the inner space of the substrate box 92 is partitioned by the inner wall surfaces 118a and 122a. Similarly, the outer wall surfaces 118b and 122b of the inner wall surfaces 118a and 122a of the peripheral wall portions 118 and 122 are connected with the boundary between them, and the boundary between the substrate box 92 and the outside is formed by the outer wall surfaces 118b and 122b. It is prescribed.

  The front side structure 102 is formed with a shielding portion 124 that covers the boundary between the peripheral wall portions 118 and 122 from the outside. More specifically, the shielding portion 124 is integrally formed along the end portion of the front side peripheral wall portion 122, and the inner surface of the shielding portion 124 is in contact with the outer surface of the back side peripheral wall portion 118 in the entire area. That is, in a state where both the structural members 101 and 102 are fixed, the boundary portion between both the peripheral wall portions 118 and 122 is closed from the outside. Moreover, the shielding part 124 has both a function as a guide means when combining the two structural bodies 101 and 102 and a function as a suppressing means for suppressing the positional deviation between the two structural bodies 101 and 102 after the combination. ing. When combining the two structural members 101 and 102, the end surfaces 119 and 123 of the peripheral wall portions 118 and 122 are guided so as to contact each other by placing the outer surface of the back-side peripheral wall portion 118 along the inner surface of the shielding portion 124. . And in the state which both the structures 101 and 102 were combined, the position shift to directions other than an assembly direction is suppressed because the outer surface of the back side surrounding wall part 118 is contacting the inner surface of the shielding part 124. FIG.

  A long hole 125 extending along the long side is formed on one long side of the front side wall 121. The perforation 125 is surrounded by the front peripheral wall 122 and the partition wall 126 of the front side wall 121.

  A connector plate 104 is disposed between the front side structure 102 and the main control board 91 so as to close the long hole portion 125. The connector plate 104 is screwed to the back side of the front structure 102 (specifically, it is fixed in a detachable state). A plurality of through holes 129 are formed in the connector plate 104 in a one-to-one correspondence with a predetermined connector group provided on the main control board 91.

  The intermediate structure 103 described above is provided in a rectangular frame-like frame part 131 that defines the outer periphery of the intermediate structure 103 and the opening of the frame-like part 131, and is connected to the frame-like part 131 via the columnar connecting part 132. The cover part 133 is integrally formed. The frame-like portion 131 is slightly smaller than the front side wall portion 121 of the front side structure 102, and specifically, is formed so as to follow the peripheral edge of the front side wall portion 121. By forming the frame-like portion 131 in this way, the intermediate structure 103 can enter the front-side structure 102.

  The cover part 133 is formed in a box shape opened to one side, and the position where the cover part 133 is provided corresponds to the mounting position of the CPU chip 93 on the element mounting surface 97 and is the opening of the frame-shaped part 131. Near the center. In this case, the opening of the cover part 133 faces one side of the opening direction of the frame-like part 131.

  A plurality of columnar connecting portions 132 that connect the cover portion 133 to the frame-like portion 131 are provided, and each columnar connecting portion 132 individually connects the frame-like portion 131 and the cover portion 133. Specifically, three columnar connecting portions 132 are provided, and two of the columnar connecting portions 132 are a cover portion and a pair of frame portions 131a and 131b that are opposed to each other with the cover portion 133 interposed therebetween in the frame-like portion 131. 133 are connected to each other. These two columnar connecting portions 132 are arranged on the same straight line with the cover portion 133 interposed therebetween. The remaining one columnar connecting portion 132 is provided so as to connect the frame portion 131c and the cover portion 133, which are different from the pair of frame portions 131a and 131b. That is, each columnar connecting portion 132 is formed in a T shape with the cover portion 133 as the center. By forming the columnar connecting portion 132 as described above, the cover portion 133 is firmly fixed to the frame-shaped portion 131 while preventing the opening of the frame-shaped portion 131 from being blocked as much as possible.

  As shown in FIG. 9, a fixing flange 134 extending outward is integrally formed with a pair of frame portions 131a and 131b opposed to the frame portion 131. A plurality of the fixing flanges 134 are provided. A fixing boss 135 having a screw hole is integrally formed on the back side of the front side wall portion 121 of the front side structure 102 in a one-to-one correspondence with the fixing flange 134. Then, the intermediate structure 103 is arranged from the back side of the front structure 102 so that the opening of the cover 133 faces away from the front side wall 121 and the corresponding fixing flange 134 and the fixing boss 135 overlap. In this state, each combination of the fixing flange 134 and the fixing boss 135 is screwed from the back side of the front 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.

  As described above, the front-side structure 102 in which the intermediate structure 103 and the connector plate 104 are integrated is different from the back-side structure 101 in which the main control board 91 is integrated with respect to the element mounting surface 97 of the main control board 91. It is combined so as to cover. In this case, the back-side peripheral wall portion 118 (specifically, the end surface 119) of the back-side structure 101 and the front-side peripheral wall portion 122 (specifically, the end surface 123) of the front-side structure 102 are in contact with each other, and the back surface of the front-side structure 102 The open portion to the side is closed by the back side structure 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.

  Further, 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 129 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 129 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 126 of the front side wall 121 on the inner side of the front side wall 121. 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.

  In addition, although the back side structure 101 and the front side structure 102 are couple | bonded by the some coupling | bonding means, the detail regarding the structure regarding the coupling | bonding of these both structures 101 and 102 is mentioned later.

  Here, 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 front-side wall portion 121 of the front-side structure 102 so as to partition a predetermined region of the front-side wall portion 121. Yes. The box-side cutting portion 151 includes a large number (or a plurality of) through-holes 152 formed so as to penetrate the front side wall portion 121 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 front side wall portion 121, and the large number of through holes 152 are arranged so as to surround a predetermined region of the front side wall portion 121. That is, the box-side cutting part 151 is formed in an intermittent annular shape surrounding a predetermined region of the front side wall part 121. 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 partitioned by the box-side cutting part 151 in the front side wall 121 is an area facing the CPU chip 93 of the main control board 91 and its periphery in the front side wall 121. 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 front side wall portion 121 in the front-side structure 102, the front side having the box-side cut portion 151 without complicating the mold structure. The structure 102 can be easily formed. That is, since the front-side structure 102 is formed in a box shape opened to one side, the direction in which the front-side structure 102 is removed after molding is naturally defined in the mold. In this case, since the through-hole 152 of the box-side cut portion 151 is formed so as to penetrate the front-side wall portion 121 in the thickness direction of the front-side wall portion 121, the above-described extraction direction of the front-side structure 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. Thereby, the box side cutting part 151 becomes a weak area | region in the front side wall part 121 compared with another site | part. In other words, the connection state between the back-side structure 101 and the front-side structure 102 due to the connection between the back-side connecting portion 141 and the front-side connecting portion 142 is determined by destroying at least one of the connecting portions 141 and 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 front side wall portion 121, and the short side portion of the opening 154 is along the short side portion of the front side wall portion 121.

  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 peripheral wall portion 122 of the front structure 102 and is fixed to the region facing the front peripheral wall portion 122 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.

  Hereinafter, the structure regarding the coupling | bonding of the back side structure 101 and the front side structure 102 is demonstrated in detail. As a means for connecting the front side structure 102 and the back side structure 101, (1) an adhesive and (2) a caulking structure are provided. Therefore, each of these coupling means will be described individually.

  The adhesive is applied to the entire area of the end surface 119 of the back-side structure 101 and the end surface 123 of the front-side structure 102. Thereby, the back side surrounding wall part 118 and the front side surrounding wall part 122 are adhere | attached, and the back side structural body 101 and the front side structural body 102 are being fixed. Since the boundary portion between the two structural members 101 and 102 is closed in this manner, even if an attempt is made to insert a fraudulent jig into the internal space of the board box 92 from the boundary portion, it is difficult to perform such an act. Yes.

  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 with reference to FIGS. 15 is a partial cross-sectional view taken along line AA in FIG.

  As shown in FIG. 8 and the like, a plurality of insertion portions 181 for inserting breaking screws 180 as coupling means are formed on the front peripheral wall portion 122. Specifically, two of the front peripheral wall portions 122 are formed on opposite wall portions. The insertion portion 181 has a long hole shape extending in the same direction as the standing direction of the front peripheral wall portion 122. That is, it has an elongated hole shape extending from the base portion (root portion) of the front peripheral wall portion 122 toward the end surface 123. More specifically, one end of the insertion portion 181 is open to the base side of the front peripheral wall portion 122, and the other end is formed to have a bottomed shape. A through hole 182 connected to the boundary portion (specifically, the end surface 123) with the back side peripheral wall portion 118 is formed at the bottom of the insertion portion 181, and the boundary portion (specifically, the back side peripheral wall portion 118 with the front side peripheral wall portion 122). Specifically, a bottomed screw hole 183 communicating with the through hole 182 is formed in the end face 119). More specifically, the center axis of the through hole 182 and the center axis of the screw hole 183 overlap each other in a state where the constituent bodies 101 and 102 are combined, that is, in a state where the end faces 119 and 123 are in contact with each other. In this state, the breaking screw 180 inserted through the insertion portion 181 is screwed into the screw hole 183, and both the peripheral wall portions 118 and 122, that is, both the constituent members 101 and 102 are fixed.

  The breaking screw 180 is set at a position where the strength of the connecting portion between the head on which the tip can be inserted into a tool such as a screwdriver and the side where the screw groove is formed is low, and cannot be tightened any further. By further applying a predetermined force to the head with the tool, the connecting portion is cut and the head is separated. That is, the breaking screw 180 cannot be rotated in the loosening direction using the tool after screwing. It should be noted that the coupling means for fixing both components 101 and 102 is limited to the breaking screw 180 as long as it is possible to prevent loosening of the coupling between the components 101 and 102 after screwing. Alternatively, a known one-way screw may be used. The head of the breaking screw 180 screwed into the back side peripheral wall portion 118 (specifically, the screw hole 183) is separated after screwing so that the breaking screw 180 cannot be loosened.

  Both the peripheral wall portions 118 and 122 are formed to be relatively thick as described above, and further, a weak portion that facilitates separation of the fixing portion by the breaking screw 180 from each of the structural bodies 101 and 102 is not 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 peripheral wall portions 118 and 122. Further, the shielding portion 124 is located on the side of the breaking screw 180, the screw hole 183, and the like. For this reason, in order to arrange | position the fracture | rupture screw 180, the access to the part which tends to become thin compared with a peripheral part is suppressed suitably.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 16, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  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.

  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 coupled 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.

  Both the box constituent bodies 101 and 102 are integrated by connecting the peripheral wall portions 118 and 122 of the box constituent bodies 101 and 102. Specifically, the peripheral wall portions 118 and 122 are fixed by the breaking screw 180. In order to release this coupled state, it is necessary to remove the box-side removal region 153 provided in advance as described above, or remove the coupling site by the breaking screw 180. When the box-side removal region 153 is removed, it is easy to confirm the trace. Further, since it is difficult to remove the breaking screw 180 itself, it is assumed that the region around the coupling site of the breaking screw 180 is removed as described above. However, even in such a case, traces of removal on the peripheral wall portions 118 and 122 are assumed. Tends to remain. For example, an opening or the like is formed in the peripheral wall portions 118 and 122. Even if the open trace of the substrate box 92 is concealed by removing the peripheral portion of the breaking screw 180 and then returning the removed portion to the same location, it is easy to find such a trace. It can be.

  Assuming a configuration in which fixing portions protruding from the outer wall surfaces 118b and 122b are formed on both the peripheral wall portions 118 and 122, and the fixing portions are coupled by a coupling means such as a break screw, the fixing portions extend along the outer wall surfaces 118b and 122b. After being cut off, it is returned to its original position by adhesion or the like, which may cause inconvenience that the trace is concealed. In such a case, there is a concern that it will be difficult to find fraud. Such an inconvenience is considered to be particularly remarkable when the root portion of the fixed portion has a fragile portion that can be easily cut. In this regard, as described above, the outer wall surfaces 118b and 122b of the peripheral wall portions 118 and 122 can be formed by suppressing the protrusion of the binding portion from the outer wall surfaces 118b and 122b and directly fixing the peripheral wall portions 118 and 122 to each other. The fixing part is not removed along the line. Therefore, it is possible to make it difficult to conceal the trace of unlocking, which can contribute to the improvement of crime prevention.

  In the present embodiment, in particular, the breaking screw 180 and the connecting portion thereof are arranged in a region sandwiched between the inner and outer wall surfaces 118a, 122a, 118b, 122b of the peripheral wall portions 118, 122, more precisely than the outer wall surfaces 118b, 122b. Arranged in the inner area. For this reason, it is possible to make it difficult to access the breaking screw 180 and its connecting portion. Therefore, it is possible to make it difficult to perform an illegal act such as releasing the coupled state by destroying the fracture screw 180 itself.

  In general, it is assumed that it is difficult to increase the thickness dimension of the peripheral wall portions 118 and 122 in consideration of heat dissipation and moldability of the substrate box 92. Temporarily, the peripheral wall portions 118 and 122 are overlapped in the thickness direction (for example, the peripheral wall portion 118 is the outer side and the peripheral wall portion 122 is the inner side), and when the breaking screw is inserted in the thickness direction, In addition, it is considered difficult to suppress the protrusion of the screw head from the outer wall surface 118b. Therefore, in the present embodiment, the mounting direction of the breaking screw 180 (that is, the central axis direction of the insertion portion 181) is the same as the standing direction of the peripheral wall portion 122. Thereby, while ensuring that the thickness dimension of the surrounding wall part 118,122 becomes large too much, the security | security of the screw part hooking and suppression of protrusion of the fracture | rupture screw 180 are made to balance suitably. In particular, since the insertion portion 181 extends in the standing direction of the peripheral wall portion 118, the breaking screw 180 can be easily separated from the opening portion of the insertion portion 181. This makes it difficult to access the breaking screw 180.

  Furthermore, since the central axis of the breaking screw 180 is along the peripheral wall portions 118 and 122 (specifically, the outer surfaces 118b and 122b and the inner wall surfaces 118a and 122a), the breaking screw 180 is worn in the thickness direction. In addition, it is easy to increase the area occupied by the fixed portions in the peripheral wall portions 118 and 122. Thereby, the removal range in the case of removing a fixed part can be enlarged, and it can contribute to the improvement of the intelligibility of the trace.

  The peripheral wall portions 118 and 122 are provided with fixing portions for fixing the components 101 and 102, and the front side wall portion 121 is provided with a box side cutting portion 151 (box side removal region 153) for exposing the main control board 91. . That is, it was set as the structure which provides a fixed site | part and an open site | part in a separate wall part. For this reason, even when the box-side removal region 153 is removed, the coupled state of the substrate boxes 92 is maintained. Therefore, unauthorized replacement of the main control board 91 can be suitably suppressed.

(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. 17 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, the coupling means for coupling the back-side structure and the front-side structure and the structure associated with the coupling means are different from those in the first embodiment. Therefore, the configuration of main controller 300 in the present embodiment will be described below with a focus on the above differences. 18 is an exploded perspective view of main controller 300 in the present embodiment, FIG. 19A is a partial cross-sectional view taken along line BB in FIG. 18, and FIGS. 19B to 19D are in a combined state. It is explanatory drawing which shows transfer.

  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. Similarly to the substrate box 92 in the first embodiment, the substrate box 302 includes a plurality of box components, a back-side component 303, a front-side component 304, an intermediate component (not shown), and a connector plate. (Not shown). As in the first embodiment, the connector plate is fixed to the front side structure 304 with a break screw, and the intermediate structure is fixed to the back side structure 303 with a break screw. Detailed descriptions of the structure and the structure of the connector plate are omitted.

  As shown in FIG. 18, the back side structural body 303 has a back side flat plate part 310 as a mounting part for mounting the main control board 301. The back side flat plate portion 310 faces the solder surface 311 of the main control board 301 and has a substantially long plate shape larger than the outer shape of the main control board 301. Further, the longitudinal direction of the back side flat plate portion 310 is set to be the same direction as the longitudinal direction of the main control board 301. On the two long side portions of the back-side flat plate portion 310, a back-side side wall portion 312 standing on the main control board 301 side is integrally formed. These back side wall portions 312 extend in a direction perpendicular to the solder surface 311 and face each other. On the other hand, the front-side structure 304 has a front-side flat plate portion 314 that faces the element mounting surface 313 of the main control board 301. The front side flat plate portion 314 also has a substantially long plate shape like the back side flat plate portion 310, and a front side wall portion 315 erected toward the back side structure 303 is integrally formed on the long side portion thereof. More specifically, the distance dimension between the front side wall parts 315 facing each other is set to be the same as the distance dimension between the back side wall parts 312 facing each other in the same direction. The end faces 316 and 317 of the side wall portions 312 and 315 are opposed to each other, and the end faces 316 and 317 are in contact with each other in a state where both the structural bodies 303 and 304 are assembled.

  A guide portion 318 that guides the front-side component 304 to a predetermined assembly completion position when the two components 303 and 304 are combined is formed on the inner front edge of the back-side side wall 312. The guide portion 318 has a groove shape extending in the longitudinal direction of the back flat plate portion 310. On the other hand, a sliding part 319 that fits on the guide part 318 and slides along the guide part 318 in contact with the inner surface of the guide part 318, specifically, the inner surface of the groove-like portion, is fitted to the front side structure 304. Is provided. More specifically, the sliding portion 319 has a ridge shape extending in the same direction as the guide portion 318 (specifically, extending along the front edge of the front side wall portion 315), and from the inner surface of the front side wall portion 315. Projecting inward of the substrate box 302. In a state where both the structural bodies 303 and 304 are combined, the guide portion 318 and the sliding portion 319 are located on the inner side of the outer wall surface 315a of the front side wall portion 315 and the outer wall surface 312a of the back side wall portion 312, that is, the substrate box. The configuration is located inside 302. Thereby, exposure of the guide part 318 and the sliding part 319 to the outside of the substrate box 302 is suppressed, and access to the guide part 318 and the sliding part 319 from the outside of the substrate box 302 is avoided.

  The guide portion 318 has a plate shape parallel to the element mounting surface 313, and is parallel to the first restriction portion 320 that restricts the movement of the sliding portion 319 in the end-hand direction of the main control board 301 and the side wall portions 312 and 315. A second restricting portion 321 for restricting the movement of the sliding portion 319 toward the front of the element mounting surface 313 is provided. By restricting the movement of the sliding portion 319 by both the restricting portions 320 and 321, the front side structural body 304 and the back side structural body 303 are separated in a direction other than a predetermined direction (specifically, the sliding direction). It has been avoided. Further, the guide portion 318 and the sliding portion 319 are suppressed from being exposed to the outside of the substrate box 302 as described above. For this reason, the inconvenience that both the components 303 and 304 are separated by destroying the guide portion 318 and the sliding portion 319 in the assembled state of both the components 303 and 304 is suitably suppressed. Note that the guide portion 318 has a substantially U-shape opened toward the outside of the substrate box 302 by both the restricting portions 320 and 321 and the like.

  In addition, an opening 322 as an insertion port for the sliding portion 319 is formed at one end portion of the guide portion 318. The sliding part 319 is inserted from the opening 322 and the front side structural body 304 is slid to assemble the both structural bodies 303 and 304. A back wall portion 323 that stands up in the same direction as the back side wall portions 312 is formed at the end of the back side structure 303 opposite to the side where the opening 322 is formed. The back wall portion 323 is provided by connecting both side wall portions 312 and 315, and forms a housing space for housing the main control board 301 together with the side wall portions 312 and 315. The end portion of the guide portion 318 opposite to the opening 322 is closed by a part of the back wall portion 323. In a state where both the structural bodies 303 and 304 are combined, one end portion of the sliding portion 319 is in contact with the back wall portion 323. That is, the front-side structure 304 inserted through the opening 322 and pushed in along the guide part 318 is restricted from moving by hitting the back wall part 323, and can reach the assembly completion position.

  On the short side of the front side structure 304 opposite to the back wall part 323, a lid part 324 that covers the open part of the back side structure 303 opposite to the back wall part 323 is formed. The lid portion 324 has a wall shape that rises from the front flat plate portion 314 toward the same side as the front side wall portion 315. And the front side wall part 315 which opposes is connected by this cover part 324. FIG. As described above, a closed space is formed in the substrate box 302 by closing the open portion of the front-side structure 304 with the lid 324 in a state where both the structures 303 and 304 are combined. ing. In addition, a wall portion facing the back wall portion 323 is formed at an end of the back side flat plate portion 310 opposite to the side where the back wall portion 323 is formed, and the back side structure 303 is opened to one side. It is also possible to make an arrangement. In such a case, the lid 324 of the front side structure 304 may be omitted.

  As shown in FIG. 19 (a), a locking tool 330 that constitutes a coupling means for both the components 303 and 304 together with the guide portion 318 and the sliding portion 319 is provided at the boundary between the side wall portions 312 and 315. Is provided. Specifically, a bottomed mounting hole 331 for attaching the locking tool 330 is formed on the end surface 316 of the back side wall 312, and the locking tool 330 is fitted in the mounting hole 331. . The locking tool 330 has an installation portion 332 installed at the bottom of the attachment hole 331, and the installation portion 332 and the bottom of the attachment hole 331 are coupled by a coupling means such as adhesion, so that The tool 330 is in a state assembled to the back side structure 303. The locking tool 330 has a projecting piece 333 provided so as to project from the mounting hole 331. The protruding piece 333 is connected to the installation portion 332 via the spring portion 334, and the movement of the mounting hole 331 in the axial direction is allowed. More specifically, the protruding piece 333 is arranged in a state of protruding from the mounting hole 331, but by applying an external force in the axial direction of the mounting hole 331, the spring part 334 is compressed, and the inside of the mounting hole 331 is compressed. It is configured to be accommodated. The installation portion 332, the protruding piece 333, and the spring portion 334 are integrally formed of a synthetic resin material. A coil spring or the like can be used instead of the spring portion 334.

  The protruding piece 333 has a substantially columnar shape extending in the same direction as the central axis of the mounting hole 331, and an inclined surface 335 is provided at an end portion on the front side structure 304 side. More specifically, the inclined surface 335 is formed on the front side in the insertion direction of the front side structure 304. In addition, the inclined surface 335 gradually descends toward the end surface 316 as the distance from the back wall portion 323 increases, and the projecting piece 333 is attached to the mounting hole 331 when the inclined surface 335 is pushed toward the insertion direction of the front side component 304. It is easy to move in the direction of the central axis, that is, in the direction of the central axis of the protruding piece 333.

  Further, the outer diameter of the protruding piece 333 is set substantially the same as the hole diameter of the mounting hole 331, and the outer peripheral surface of the cylindrical portion of the protruding piece 333 is in contact with the inner peripheral surface of the mounting hole 331. As a result, movement of the mounting piece 333 in the radial direction of the mounting hole 331 is restricted, and rattling when moving in the axial direction of the mounting hole 331 as described above is suppressed. The contact state between the outer peripheral surface of the cylindrical portion of the protruding piece 333 and the inner peripheral surface of the mounting hole 331 is set so as to be secured even at the maximum protruding position of the protruding piece 333.

  A bottomed round hole 336 corresponding to the protruding piece 333 is formed in the front side wall portion 315 (specifically, the end surface 316) of the front side structure 304. The round hole 336 is arranged so as to communicate with the mounting hole 331 in a state where the front-side structure 304 is in contact with the back wall portion 323, that is, in a state where the front-side structure 304 has reached the assembly completion position. Yes. Further, the hole diameter of the round hole 336 is set to be substantially the same as the hole diameter of the mounting hole 331 (specifically, the outer diameter of the protruding piece 333), and the protruding piece 333 is fitted into the round hole 336. It has become. Thus, in the state in which the protruding piece 333 is fitted, the peripheral surface of the cylindrical portion of the protruding piece is in contact with both the inner peripheral surface of the round hole 336 and the inner peripheral surface of the mounting hole 331, and the front side configuration Movement of the body 304 toward the opening 322 (that is, movement of the front side structure 304 in the removal direction) is restricted.

  Here, based on FIG. 19, the assembly | attachment operation | work of the front side structure 304 and the back side structure 303 is demonstrated. When assembling both components 303 and 304, the locking tool 330 operates in the order of FIG. 19 (b) → FIG. 19 (c) → FIG. 19 (d).

  In order to attach the front side structural body 304 to the back side structural body 303, first, the sliding portion 319 of the front side structural body 304 is inserted into the opening 322 of the back side structural body 303. Then, the front side structural body 304 is slid back (indented) along the guide portion 318. As shown in FIG. 19B, when the front side structural body 304 is slid by a predetermined amount, the end portion of the sliding portion 319 comes into contact with the inclined surface 335 of the locking tool 330. Further, by pushing the front side structure 304, the spring portion 334 is bent, and the protruding amount of the protruding piece 333 is reduced. As a result, the protruding piece 333 is completely buried in the mounting hole 331. In such a state, the protruding piece 333 is held while being pressed by the end surface 316. That is, the protruding piece 333 is held while being biased toward the end surface 316 by the spring portion 334. When the front side structure 304 is pushed in until it contacts the back wall 323, the round hole 336 of the front side structure 304 and the mounting hole 331 of the back side structure 303 communicate with each other, and the protruding piece 333 is urged by the biasing force of the spring part 334. Protrudes into the round hole 336. Thus, when the protruding piece 333 protrudes into the round hole 336, the protruding piece 333 is caught in both the holes 331 and 336, and the movement of the front side structural body 304 in the removal direction is restricted. Thereby, the front side structural body 304 and the back side structural body 303 are in a fixed state.

  Also in the present embodiment, similarly to the first embodiment, a box-side cutting portion 340 is provided in the front-side structure 304, and the box-side cutting portion 340 is cut by a tool such as a nipper or a cutter. The box-side removal region 341 can be removed. By removing the box-side removal region 341, the internal space of the substrate box 302 is opened, and a part of the element mounting surface of the main control substrate 301 is exposed. Then, by removing the cover (not shown) of the intermediate structure that covers the CPU chip 342, the CPU chip can be removed.

  According to the present embodiment described in detail above, the following special effects are obtained in addition to the same effects as those of the above-described embodiments. That is, since the locking tool 330 is accommodated in the closed space sandwiched between the two side wall portions 312, 315, exposure to the outside is suppressed. For this reason, access to the locking tool 330 from the outside of the board box 302 is avoided. Therefore, it is possible to suitably suppress the occurrence of an inconvenience that the combined state of the two structural bodies 303 and 304 is illegally released by breaking or removing the locking tool 330. Thereby, further improvement of crime prevention can be expected.

  In addition, since the assembly is completed by sliding the front side structural body 304 along the guide portion 318, it is not necessary to separately perform the fixing work by the locking tool 330. Thereby, it is possible to suppress complication of assembling work. Then, by simplifying the work, it is possible to make it difficult to cause the inconvenience that the main controller 300 is distributed without being completely assembled due to operator error, that is, not completely fixed.

  Further, the guide part 318 and the sliding part 319 formed in each of the structural bodies 303 and 304 enable slide mounting as described above, and restrict the separation of the both structural bodies 303 and 304 after the mounting is completed. As described above, a practically preferable configuration is realized by providing the guide portion 318 and the sliding portion 319 together with an improvement in wearability and a fixing function between the two components 303 and 304.

  However, while the slide portion can be mounted by the guide portion 318 and the slide portion 319, the above-described beneficial effects can be enjoyed. On the other hand, the guide portion 318 and the slide portion 319 are destroyed, so that both configurations There is a possibility that the bodies 303 and 304 may be separated. In particular, when the guide portion 318 and the sliding portion 319 are formed on the outer side of the outer wall surface 315a of the front side wall portion 315, the traces of destruction are cleverly cut by cutting along the outer wall surface 315a. May be hidden. In such a case, it may be difficult to grasp that fraud has been performed. In this regard, in the present embodiment, the guide portion 318 and the sliding portion 319 are disposed on the inner side of the outer wall surface 315a of the front side wall portion 315, and access from the outside of the substrate box 302 is prevented. For this reason, in order to remove the guide part 318 and the sliding part 319, it is necessary to first destroy the front side wall part 315 and the like. And when the front side wall part 315 etc. are destroyed, the trace will remain as an opening etc. Thus, concealment of the destruction traces as described above can be suitably suppressed by making the destruction traces conspicuous. Therefore, it is possible to improve workability during assembly while ensuring crime prevention.

  In addition, the outer wall surfaces 312a and 315a are configured to be continuous with the boundary portion between the peripheral wall portions 312 and 315 interposed therebetween. For this reason, a step between the outer wall surfaces 312a and 315a at the boundary portion (specifically, a step in the thickness direction of the peripheral wall portions 312 and 315) is less likely to occur. For this reason, it is difficult to find inconveniences such as access to the fixture 330 and the like while making it difficult to find a trace by excising the step portion along the outer wall surface.

  The mounting holes 331 and the round holes 336 communicate with each other by combining both the structural bodies 303 and 304, and a closed space is formed in the side wall portions 312 and 315. Since the locking tool 330 is accommodated in the closed space formed in this way, access to the locking tool 330 from the outside of the board box 302 is preferably avoided. Thereby, generation | occurrence | production of the problem that the latching state of the latching tool 330 is illegally cancelled | released can be suppressed, and the further improvement of crime prevention can be contributed.

  Note that the technical idea in this embodiment (specifically, the technical idea of isolating the coupling means in the peripheral wall portion) can also be applied in combination with the first or second embodiment.

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

  In addition, regarding part names and member names that are commonly used in a plurality of embodiments, only the part numbers and member numbers used in one embodiment are described, but this is described. It is not limited to. That is, it is also possible to apply the part number and member number used in other embodiments specified in advance.

  (1) FIGS. 20A and 20B show a modification of the board box of the main controller. FIGS. 20A and 20B are explanatory views for explaining a modification of the substrate boxes 271 and 281. FIG.

  (1-1) In the substrate box 271 shown in FIG. 20A, the box-side cutting portion 272 is formed not only on the front-side structure 273 but also on the back-side structure 274. Specifically, the box-side cutting part 272 is formed between the back-side cutting part 275 formed between the pair of opposing edges in the back-side structure 274 and between the pair of facing edges in the front-side structure 273. And a formed front-side cutting part 276. Both the back-side cutting part 275 and the front-side cutting part 276 are configured by arranging a large number of through-holes penetrating inside and outside the substrate box 271.

  The box-side cutting part 272 has an intermittent annular shape across the boundary portion between the back-side structure 274 and the front-side structure 273 by the back-side cutting part 275 and the front-side cutting part 276. Further, the position where the box-side cutting part 272 is formed is a position biased toward one short side of the substrate box 271.

  In the substrate box 271, the internal space of the substrate box 271 is opened by cutting the box side cutting part 272 over the entire circumference. In this case, the main control board is provided so that it can be extracted from the board box 271 in a state where the box-side cutting part 272 is cut over the entire circumference to open the inner space of the board box 271.

  According to this configuration, similarly to the first embodiment, the box-side cutting portion 272 may be cut when the internal space of the substrate box 271 is opened. Therefore, the back-side structure 274 and the front-side structure 273 are separated from each other. Even if the fixing is performed in a state where the fixing is not intended to be released, it is possible to suppress a decrease in workability of the inspection of the main control board and the like.

  (1-2) In the substrate box 281 shown in FIG. 20B, the box-side cutting part 284 is formed in the surface constituting part 283 of the front-side constituting body 282, as in the first embodiment. 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.

  (2) FIGS. 21A and 21B show a modification of the box side cutting portion 151 formed in the substrate box 92 of the main control device 63. FIGS. 21A and 21B are explanatory views for explaining a modification of the box-side cutting portion 151. FIG.

  (2-1) The box-side cutting portion 151 shown in FIG. 21A is provided by forming a bottomed groove instead of a through-hole penetrating into and out of the substrate box. In addition, the said groove | channel is not limited to a cross-sectional V shape, A U shape may be sufficient. Even in this configuration, since the box-side cutting portion 151 is formed in the substrate box, the same effects as those in the first embodiment can be obtained with respect to opening the internal space of the substrate box. Further, in this configuration, the box-side cutting portion 151 does not function as a vent, but an act of trying to insert a fraudulent jig through the box-side cutting portion 151 is not performed. The frame portion 131 of the structure 103 may be omitted.

  (2-2) The box-side cutting portion 151 shown in FIG. 21B is not a through hole or groove that penetrates into or out of the substrate box 92 but is weaker than the material constituting the other part of the substrate box 92. It is provided by applying material. Even in this configuration, since the box-side cutting portion 151 is formed in the substrate box 92, it is possible to obtain the same effect as the first embodiment with respect to the opening of the internal space of the substrate box 92. Further, in this configuration, the box-side cutting portion 151 does not function as a vent, but an act of trying to insert a fraudulent jig through the box-side cutting portion 151 is not performed. The frame portion 131 of the structure 103 may be omitted.

  (3) FIG. 22 shows a modification of the positional relationship between the through hole 152 of the box-side cutting part 151 and the frame-like part 131 of the intermediate structure 103 in the substrate box 92 of the main control device 63. FIG. 22 is an explanatory diagram for describing a modification of the positional relationship between the through hole 152 and the frame-like portion 131.

  As shown in FIG. 22, the intermediate structural body 103 is provided in contact with the back surface of the front side wall portion 121 of the front side structural body 102, and the frame-shaped portion 131 of the intermediate structural body 103 penetrates the box side cutting portion 151. The hole 152 is closed on the inner space side of the substrate box 92. According to this configuration, the box-side cutting portion 151 does not function as a vent, but when an illegal jig is inserted through the box-side cutting portion 151, the internal space of the substrate box 92 is illegal. It is possible to prevent the unauthorized jig from entering before the jig is inserted.

  (4) In the first embodiment, the intermediate structure 103 having the frame-shaped part 131 and the cover part 133 is provided separately from the front-side structure 102. Instead, the frame-shaped part 131 and the cover are provided. The part 133 may be formed integrally with the front side structure 102. Further, only the frame-like portion 131 may be provided as the intermediate structure 103 and the cover portion 133 may be fixed to the main control board 91. Further, the frame-like portion 131 may be integrally formed with the front side structure 102 and the cover portion 133 may be fixed to the main control board 91. Further, the intermediate structure 103 may be omitted. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (5) In the first embodiment, the box-side cutting portion 151 is formed on the front-side structure 102, but the box-side cutting portion may be formed on the back-side structure 101. Further, the box-side cut portion may be formed so as to surround a predetermined region in the back-side structure 101 and the box-side cut portion may be formed so as to surround the predetermined region in the front-side structure 102. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (6) In the first embodiment, the substrate-side cutting portion 161 is formed in a frame shape, but is not limited to this, and can be taken out through the opening 154 formed in the substrate box 92. If the substrate-side removal region 163 can be separated, the shape of the substrate-side cutting part 161 is arbitrary. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (7) The number and arrangement position of the columnar connecting portions 132 of the intermediate structure 103 may be different from those in the first embodiment. Further, in the columnar connecting portion 132, a weakened portion that is weaker than other portions of the columnar connecting portion 132 may be formed on at least one of the base on the cover portion 133 side or the root on the frame-shaped portion 131 side. In this case, the cutting operation of the columnar connecting portion 132 can be performed satisfactorily. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (8) In the first embodiment, the provisional storage configuration after the inspection of the CPU chip 93 and the substrate-side removal region 163 may be omitted. In addition, a configuration of provisional storage may be applied to the cover unit 133 so that the CPU chip 93 can be covered again by the cover unit 133 after the inspection of the CPU chip 93 and the substrate-side removal region 163. In addition, when temporarily storing the CPU chip 93 and the substrate-side removal region 163 after the inspection, it is possible to temporarily store the plate surface on the side on which the CPU chip 93 is mounted toward the back side structure 101 side. Also good. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (9) In the first embodiment, the CPU chip 93 in which the CPU, the ROM, and the RAM are integrated into one chip is mounted on the main control board 91. However, instead of this, an element dedicated to the ROM is mounted on the main control board 91. May be installed. In this case, each configuration of the substrate box 92 in the first embodiment may be applied to at least the element dedicated to the ROM. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (10) In the first embodiment, the board box 92 of the main controller 63 does not include the intermediate structure 103 and the connector plate 104, and the front-side structure 102 does not include the long hole portion 125. It is good also as a structure. In this case, the substrate box 92 is formed from a pair of box structures 101 and 102. Moreover, it is good also as a structure by which the board | substrate box 92 is formed by combining 3 or 5 or more box structure bodies instead of 4 box structure bodies. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (11) As a fixture for fixing the back side coupling portion 141 and the front side coupling portion 142, a hook metal fitting may be used instead of the breaking screw 143. In this case, after the coupling portions 141 and 142 are fixed by the hook metal fittings, the coupling metal portions 141 and 142 can be removed when the coupling portions 141 and 142 are unfixed. Will require destruction. Moreover, as a structure which fixes the back side coupling | bond part 141 and the front side coupling | bond part 142, it is good also as a structure which fixes both the coupling parts 141 and 142 using an adhesive instead of the structure which uses a fixing tool as mentioned above, It is good also as a structure which unites both the coupling parts 141 and 142 using an ultrasonic wave or a heat | fever. Further, both coupling portions 141 and 142 may be provided for all sides of the substrate box 92.

  (12) In the first embodiment, the adhesive is applied to the boundary portion between the back-side peripheral wall portion 118 and the front-side peripheral wall portion 122, but instead of this, both the peripheral wall portions 118, 122 are superposed. They may be integrated using sound waves or heat. Further, the entire board box 92 may have a function of defining the internal space of the board box 92. Note that this configuration may be applied to the second embodiment or the third embodiment.

  (13) In the first embodiment, when the box-side removal region 153 is removed by cutting the box-side cutting portion 151, the box-side removal region 153 has an opening that opens the internal space of the substrate box 92. Although it is spaced apart from the initial position as described above, it may be configured to remain on the front side structure 102 side by being partially connected to the front side structure 102.

  (14) In each of the first to third embodiments, only the CPU chip 93 is covered by the cover portion 133 of the intermediate structure 103. In addition to this, other IC chips (for example, latch ICs) are used. The chip 95 or the like may be covered.

  (15) 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.

  (16) In each of the first to third embodiments, the entire columnar connecting portion 132 of the intermediate structure 103 is configured to have the same strength. However, the strength of a predetermined portion in the columnar connecting portion is different. You may set so that it may become weak compared with the intensity | strength of this 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.

  (17) In each of the first to third embodiments, the main control board 91 is provided with the substrate-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.

  (18) 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.

  (19) 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 is overlapped with the frame-like portion 131, and when the box-side removal region 153 is removed, the box-side removal region 153 is prevented from falling into the substrate box 92. 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.

  (20) In each of the above embodiments, the CPU chip 93 and the like are stored in the closed space formed by the cover portion 133 and the like in order to regulate 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 direction of CPU chip 93 instead of a cover part.

  (21) 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. After that, the main control board 91 is exposed by separating the constituent bodies 101 and 102.

  (22) In each of the above embodiments, both the back side structure 101 and the front side structure 102 are configured to have a box shape that is released toward the opposite side (the main control board 91 side). It is not necessarily limited to this. One of the back-side structure 101 and the front-side structure 102 may have a plate shape that closes the other open portion. For example, as shown in FIG. 23A, the front-side structure 350 may be formed in a plate shape, and the front-side structure 350 may be configured to block the opening portion of the back-side structure 351 that forms a box shape. Thus, when the open part of the back side structural body 351 is covered by the front side structural body 350, the insertion part 353 is formed in the front side structural body 350 to extend in the thickness direction thereof, and the breaking screw 352 is inserted, and the insertion part 353 is broken. It is preferable that the screw 352 be accommodated.

  Further, as shown in the first embodiment, it is also possible to form an insertion portion that extends in the standing direction of the wall surface portion 354 on the wall surface portion 354 of the back side structure 351 and inserts a breaking screw. By forming the insertion hole in the wall surface portion 354 as in the latter case, it is easier to increase the distance from the opening portion of the insertion hole to the fracture screw than in the case of forming the insertion hole in the front side structure 350. This makes it difficult to access the breaking screw from the outside of the main control device 63, and makes it difficult to cause inconveniences such as unauthorized removal of the breaking screw.

  (23) In each of the above embodiments, the peripheral wall portions 118 and 122 are fixed in contact with each other at their end surfaces 119 and 123. However, this may be changed as follows. That is, as shown in the substrate box 355 of FIG. 23B, one outer wall surface of both the peripheral wall portions 362 and 363 in both box constituting bodies 360 and 361 may be brought into contact with the other inner wall surface. More specifically, the peripheral wall portions 362 and 363 may be arranged so as to overlap the inside and outside of the substrate box 355, and the main control board 91 may be enclosed by the both peripheral wall portions 362 and 363 in an internal and external double manner. In such a case, the outer peripheral wall portion 363 located outside is formed with an insertion portion 364 and a through hole 365 extending in the overlapping direction of both the peripheral wall portions 362 and 363 (that is, the thickness direction of the outer peripheral wall portion 363), and the inner peripheral wall portion Screw holes 366 are formed in 361, and both peripheral wall portions 362 and 363 may be fixed to each other by a break screw 367 inserted through the through holes 365 and the screw holes 366. However, in this configuration, unlike the configuration shown in the first embodiment, it is assumed that it is difficult to secure a distance from the opening portion of the insertion portion 364 to the breaking screw 367. That is, in order to increase the distance, it is necessary to increase the thickness dimension of the outer peripheral wall portion 363. Such an increase in the thickness dimension may lead to inconveniences such as heat dissipation and deterioration of moldability. Therefore, it is difficult to increase the distance from the opening portion of the insertion portion 364 described above to the breaking screw 367, and access to the breaking screw 367 from the outside of the main control device 63 can be facilitated. This is not desirable from the viewpoint of crime prevention.

  (24) In each of the above embodiments, the thicknesses of both peripheral wall portions 118 and 122 are the same, but the present invention is not limited to this, and either one may be set to be thicker than the other. . Moreover, although it was set as the structure where the inner surface of both the surrounding wall parts 118 and 122 straddled the boundary of both the surrounding wall parts 118 and 122, it is not limited to this. For example, it is possible to adopt a configuration in which the inner surfaces of both peripheral wall portions 118 and 122 form a step at the boundary portion between both peripheral wall portions 118 and 122.

  (25) In the first embodiment, the front side structure 102 is fixed by the breaking screw 143, but the back side structure 101 may be fixed. Specifically, an insertion portion and a through hole may be formed in the back side structure 101 and a screw hole may be formed in the front side structure 102.

  (26) In the first embodiment, the shielding portion 124 that covers the boundary portion between the peripheral wall portions 118 and 122 from the side is provided, but a configuration in which the shielding portion 124 is not provided is also possible.

  (27) In the first embodiment, the shielding portion 124 is in contact with the outer peripheral surface of the back-side peripheral wall portion 118. However, the shielding portion 124 has a predetermined interval between the outer peripheral surface of the back-side peripheral wall portion 118. A clearance may be provided. However, the shielding part 124 has a function as a guide part when the two structural members 101 and 102 are combined. However, if the clearance is increased, this guide function may be difficult to be used. Note that the shielding portion 124 may be provided not on the front side structure 102 but on the back side structure 101.

  (28) In the first embodiment, the peripheral wall portions 118 and 122 are fixed by the two connecting means of the breaking screw 143 and the adhesive, but only one of these two connecting means is used. It may be fixed.

  Hereinafter, a specific example is shown based on (c) of FIG. Locking metal fittings 374 are attached to the front side peripheral wall 371 of the front side structure 370 and the back side peripheral wall 373 of the back side structure 372 to connect them.

  More specifically, the peripheral wall portions 371 and 373 are each formed with a concave portion 375 that is continuous with the peripheral wall portions 371 and 373, and a locking fitting 374 is disposed in the concave portion 375. The locking metal fitting 374 includes an elongated plate-like main body 376 that straddles the boundary between the peripheral wall portions 371 and 373, and an arm that extends from the end of the main body 376 on the front-side component 370 side toward the inside of the substrate box 377. Part 378. A through-hole 379 that penetrates into and out of the substrate box 377 is formed in the front-side peripheral wall portion 371 (specifically, the recess 375) of the front-side structure 370, and the arm portion 378 is inserted into the through-hole 379. Yes. In the center of the arm portion 378, an inclined portion 380 is formed which is cut and raised with the tip side as a root. The inclined portion 380 is open from the distal end side to the proximal end side of the arm portion 378 and outward of the arm portion 378 (that is, the side away from the boundary portion between the peripheral wall portions 371 and 373). Since the tip end portion of the inclined portion 380 is hooked on the inner wall surface of the front peripheral wall portion 371, the locking metal fitting 374 is prevented from coming off. The arm portion 378 can be bent and deformed (specifically elastic deformation) with the base portion as a base end. When the locking fitting 374 is attached, the inclined portion 380 is bent, that is, folded, by the arm portion 378 being inserted into the through hole 379. After the inclined portion 380 passes through the through-hole 379, the tip portion of the inclined portion 380 comes into contact with the inner wall surface of the front peripheral wall portion 371 as described above by returning to the original state by its own elastic force in the substrate box 377. It will be in the state.

  Similarly, an arm portion 381 extending from the end of the main body portion 376 on the back-side structure 372 side toward the inside of the substrate box 377 is provided on the back-side structure 372 side. An inclined portion 382 is formed at the center. A through-hole 383 corresponding to the arm portion 381 and the inclined portion 382 is formed in the back side peripheral wall portion 373 (specifically, the concave portion 375). With these arm portions 381 and the like, the locking metal fitting 374 is attached to the back side peripheral wall portion 373 of the back side structure 372. Thus, by attaching the locking metal fitting 374, both the peripheral wall portions 371 and 373 are fixed.

  (29-2) The front side peripheral wall portion of the front side structural body is attached to the front side peripheral wall portion, and the back side peripheral wall portion of the back side constituent body is attached to the receiving metal fitting on which the locking bracket is hooked. It is also possible to adopt a configuration in which the rear peripheral wall portion is fixed. A specific example will be described below with reference to FIG. The board box 390 has a front-side structure 400 and a back-side structure 402 as main components as in the above embodiments. Hole portions 404 and 405 communicating with each other are formed in the front side peripheral wall 401 of the front side structure 400 and the back side peripheral wall 403 of the back side structure 402. A locking metal fitting 410 is fixed to the hole 404 of the front side peripheral wall 401, and a receiving metal 420 that is hooked to the locking metal 410 is fixed to the hole 405 of the back side peripheral wall 403. The locking metal fitting 410 has an arm portion 411 extending toward the receiving metal fitting 420, and an inclined portion 412 that is cut and raised with the distal end side of the arm portion 411 as a root is formed at the approximate center of the arm portion 411. Yes. The inclined portion 412 is in an open state from the distal end side to the proximal end side of the arm portion 411 toward the inside of the substrate box 390 (that is, the receiving metal 420 side). On the other hand, the metal fitting 420 has a locking portion 421 provided at the opening portion of the hole portion 405, and the opening of the hole portion 405 is narrowed to such an extent that only the arm portion 411 can be inserted by the locking portion 421. Yes.

  The arm portion 411 and the inclined portion 412 are inserted into the hole portion 405 through this opening portion, and the tip end of the inclined portion 412 is caught by the locking portion 421. Thus, both the surrounding wall parts 401 and 403 are in the fixed state by the metal fittings 410 and 420 being hooked. Note that the inclined portion 412 in this different example is also provided so as to be able to be bent and deformed, similarly to the inclined portion 380. When the inclined portion 412 is inserted into the hole portion 405, the inclined portion 412 comes into contact with the locking portion 421 and bends with the base portion of the inclined portion 412 as a base end. As a result, catching with the locking portion 421 is avoided, and the inclined portion 412 is accommodated in the hole portion 405. When the entire inclined portion 412 is fitted in the hole 405, the original state is restored by the elastic force, and the tip portion of the inclined portion 412 is caught by the locking portion 421. Thus, both the metal fittings 410 and 420 are hooked, so that the two structural bodies 400 and 402 are fixed. In such a configuration, there is a possibility that the positional deviations of the two structural bodies 400 and 402 may occur in parallel with the surface of the element mounting surface 97 of the main control board 91. Therefore, as in the first embodiment, it is desirable to have a configuration in which the positional deviation between the two structural bodies 400 and 402 is regulated by the shielding portion 430.

  (30) In each of the above embodiments, the box-side cutting portion 151 and the like are provided as a configuration that facilitates the opening of the substrate box 92 and the like. However, this can be omitted. Moreover, although the board | substrate side cutting part 161 was provided as a structure which makes removal of the main control board 91 easy, it is also possible to abbreviate | omit this. Furthermore, although it was set as the structure provided with the intermediate structure 103 which covers the CPU chip 93, this is also omissible.

  (33) 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.

  (34) 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.
