Description

  The present invention relates to a gaming machine.

  As multiple types of gaming machines, pachinko gaming machines and slot machines are known. These gaming machines include a control board on which electronic components such as a ROM storing a CPU and a control program related to a game are mounted, and a series of games are controlled by the control board. In recent years, there are CPUs and ROMs that are made into one chip and mounted on a control board.

  In this type of gaming machine, for the purpose of obtaining illegal profits, control such as changing the contents of the game by exchanging the ROM in the control board (if the CPU or ROM is a single chip, the chip) Many fraudulent acts against substrates have been reported, and various fraud countermeasures have been studied.

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

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

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 (substrate box 92) in which the control board is accommodated.
The board box is
A first box structure (for example, the back-side structure 101) and a second box structure (for example, the front-side structure 102) that form at least a part of the internal space of the substrate box by being combined with each other;
A coupling means (for example, coupling mechanism 175) for coupling the first box structure and the second box structure to each other;
The gaming machine characterized in that the coupling means is accommodated in the internal space.

  According to the means 1, the coupling means for coupling the first box structure and the second box structure is accommodated in the internal space of the substrate box. Thereby, exposure of the coupling means to the outside of the substrate box can be avoided, and access (physical contact) to the coupling means from the outside of the substrate box can be suppressed. By making it difficult to access the coupling means in this way, it is difficult to release the coupled state of both box structures, and the act of illegally opening the board box can be suitably suppressed.

  Further, even if the coupling means is skillfully destroyed and the destruction trace is concealed, the destruction of the substrate box is indispensable for the destruction of the coupling means. The fact that the destruction trace remains with the destruction of the substrate box makes it possible to easily discover the fact that the substrate box has been opened.

  Mean 2. The first box structure and the second box structure are coupled by the coupling means, so that the first box structure and the second box structure cannot be separated from each other. The gaming machine described in 1.

  According to the means 2, it becomes difficult to access the internal space from the outside of the substrate box after the internal space is partitioned because the separation of the first box structure and the second box structure becomes impossible. Become. As a result, unauthorized access to the coupling means can be suitably suppressed.

  Means 3. The coupling means shifts to a coupled state based on a change in the relative positions of the first box structure and the second box structure during the combination work of the first box structure and the second box structure. The gaming machine according to means 1 or 2, characterized by the above.

  In the configuration in which the coupling means is accommodated in the internal space of the board box, the exposure of the coupling means can be suppressed and the crime prevention can be improved as described above, but the coupling is caused by the difficulty in accessing the coupling means. There is a concern that the work becomes complicated. In this regard, as shown in this means, if the joining means is configured to shift to the joining state based on the change in the relative position of the box structure during the combination work, the joining work is performed without directly touching the joining means. be able to. Thereby, it can contribute to improvement of crime prevention property, avoiding complication of a joint operation.

  In addition, since it is not necessary to form the opening for coupling work etc. in a board | substrate box, a preferable structure can also be implement | achieved also from a viewpoint of unauthorized entry prevention.

Means 4. When the first box structure and the second box structure are combined with each other, the defining means (the inner wall surface 122a of the front peripheral wall 122 and the shielding) defines the relative movement direction of the two box structures in a predetermined direction. Part 124),
The gaming machine according to any one of means 1 to 3, wherein the coupling means is shifted to a coupled state based on relative movement of the two box structural members in the predetermined direction.

  According to the means 4, it is possible to shift the coupling means to the coupled state by performing a combination operation of both box structures. For this reason, in addition to the work of combining both box components, no separate work for joining the joining means is required, and the work can be simplified. In particular, when the coupling means is configured to be accommodated in the internal space of the substrate box, it may be difficult to perform the coupling operation after completing the assembly of the box structure. For this reason, for example, it is necessary to perform the assembling work of the box structure and the joining work of the joining means in parallel. In such a case, workability may be deteriorated due to such parallel work. In this respect, in this means, since both operations can be completed by one operation, it is possible to preferably avoid the occurrence of the inconvenience described above.

  In addition, since the direction of relative movement is defined by the defining means, it is possible to make it difficult for the inconvenience that the transition to the coupled state is not performed due to work variation or the like.

  Means 5. The defining means is disposed so as to face the boundary portion of the first box structure and the second box structure from the inside of the substrate box, and shields the boundary. A gaming machine according to claim 4.

  According to the means 5, the defining means is opposed from the inner side of the substrate box to the boundary portion between the two box structures. For this reason, even if an unauthorized tool or the like is inserted from the outside of the board box through the boundary portion, it is difficult to access the internal space (for example, the coupling means) of the board box because the unauthorized tool hits the defining means. Can be. That is, by providing the defining means with a shielding function that shields the boundary portion, it is possible to contribute to improvement of crime prevention while suppressing complication of the configuration, and to realize a practically preferable configuration.

  Means 6. The gaming machine according to any one of means 1 to 5, wherein a plurality of the coupling means are provided, and each of the coupling means is spaced apart from a plurality of different locations.

  According to the means 6, the first box structure and the second box structure are combined at a plurality of portions, thereby making it easy to suppress the separation of the two box structures and the expansion of the boundary portion between the box structures. be able to. Thereby, the further improvement of crime prevention can be expected.

  When a plurality of coupling means are set, it is necessary to perform a coupling operation at each coupling location, and there is a concern that the assembling work of the board box is likely to be complicated. In this regard, particularly in the combination with the means 4 or the like (the structure in which the relative movement direction of the two box structural bodies is defined by the defining means), the coupling means is shifted to the coupled state along with the combination work of the box structural bodies. It has an excellent feature. For this reason, it can contribute to the improvement of crime prevention property, suppressing the deterioration of workability | operativity accompanying the increase in a coupling | bond part.

  For example, the coupling means may be scattered along the boundary portion of the first box structure and the second box structure or along the peripheral edge of the control board.

Mean 7 The first box configuration body has at least a first partition wall portion (for example, a back side flat plate portion 111) facing the plate surface of the control board,
The second box structure has at least a second partition wall portion (for example, the front side wall portion 121) facing the surface opposite to the plate surface,
The gaming machine according to any one of means 1 to means 6, wherein the first partition wall portion and the second partition wall portion are coupled to each other by the coupling means.

  According to the means 7, the partition wall portions provided with the control board interposed therebetween are coupled by the coupling means. Thereby, it is possible to easily suppress the overlap between the coupling means and the control board in the direction of the control board (specifically, the plate surface). More specifically, when the coupling means is arranged along the plate surface of the control board, for example, the peripheral wall portions continuous to both the first partition wall portion and the second partition wall portion are coupled by the coupling means. In this case, it is assumed that the overlap between the coupling means and the control board in the surface direction of the control board (specifically, the plate surface) becomes large. As described above, when the overlap between the control board and the coupling unit becomes large, there is a concern that the operation for confirming the control board is likely to be hindered by the coupling unit. In this regard, as described above, if the overlap between the control board and the coupling means is suppressed, even if the coupling means is housed in the board box together with the control board, it is difficult to impair the visibility of the control board.

  Further, the thickness dimension of the control board is likely to be relatively smaller than the longitudinal dimension and the lateral dimension of the control board. As described above, if the bonding is performed at a portion where the distance between the objects to be combined is small, the combined state is easily strengthened.

  Particularly in the combination with the means 5 (configuration in which the defining means is opposed to the boundary part), the defining means can be arranged between the coupling means and the boundary part. In this way, by disposing the defining means between the coupling means and the boundary portion, unauthorized access to the coupling means can be made more difficult.

Means 8. The coupling means includes
A first columnar portion (back side spacer portion 181 and the like) that rises from the first partition wall portion to the second partition wall portion side;
A second columnar portion (front side spacer portion 191 or the like) that rises from the second partition wall portion toward the first partition wall portion side;
The gaming machine according to means 7, wherein the first columnar portion and the second columnar portion are coupled to each other in a state in which end portions (contact surfaces 182 and 192) facing each other are in contact with each other.

  According to the means 8, by making the first columnar part and the second columnar part function as spacers, it is possible to suitably realize the coupling of the two partition wall parts facing each other with the internal space therebetween.

  Moreover, since the 1st partition wall part and the 2nd partition wall part are facing the board surface of a control board, it is assumed that the support part etc. which suppress the bending of these partition wall parts are hard to be set. When these partition wall portions are bent, there is a possibility that, for example, a boundary portion between the box constituents is expanded, or the partition wall portion and the control board (specifically, an element or the like) are in contact with each other. In this respect, according to the present means, the end portions of both columnar portions are in contact with each other. For this reason, when both are united and united, the function as a support part can be provided. Thereby, both the box structures can be supported at a position close to the center of the substrate box, and the substrate box can be made stronger.

  Means 9. The gaming machine according to any one of means 1 to 8, wherein each box component has transparency.

  By accommodating the coupling means in the substrate box, confirmation of the coupling means and the coupled state can be difficult. In this regard, as shown in the present means, each box structure has a transparent structure, so that the joining means and the joining state can be visually confirmed. Thereby, even if the coupled state is illegally released or the like, the confirmation can be performed without opening the substrate box or the like, so that a practically preferable configuration can be realized.

  Means 10. At least one plate surface of the control board constitutes an element mounting surface (element mounting surface 97) on which an element (CPU chip 93 or the like) storing a game control program is mounted, and on the element mounting surface side The gaming machine according to means 9, wherein a coupling portion (for example, a stopper portion 184 and an inclined portion 197) of the coupling means is located.

  In general, the element mounting surface side of the control board is likely to be fraudulent and subject to confirmation work. If the coupling part in the coupling means is arranged on the element mounting surface side of the control board, it is possible to preferably avoid the inconvenience that the coupling part becomes difficult to see by the control board itself, and the element mounting surface confirmation work and the coupling part confirmation work Can be performed from the same side. Thereby, even if a coupling | bonding means is accommodated in a board | substrate box, the visibility can be ensured and it can make it easy to avoid complication of a confirmation operation | work.

Means 11. 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 (substrate box 92) in which the control board is accommodated.
The board box is
A first box structure (for example, the back-side structure 101) and a second box structure (for example, the front-side structure 102) that form at least a part of the internal space of the substrate box by being combined with each other;
A coupling means (for example, coupling mechanism 175) for coupling the first box structure and the second box structure to each other;
Each box structure has a partition wall portion (for example, the back side peripheral wall portion 118 and the front side peripheral wall portion 122) having a substantially constant thickness that partitions the internal space and the external space of the substrate box,
The gaming machine characterized in that the coupling means is accommodated in the internal space.

  According to the means 11, the same effect as that shown in the means 1 can be obtained. The technical ideas shown in the means 2 to means 10 can be applied to this means.

  In the configuration having a plurality of “partition wall portions”, the thicknesses of the respective partition wall portions may be the same or different.

Means 12. An element (CPU chip 93 or the like) that stores a game control program is mounted on the control board,
The defining portion that defines the internal space of the substrate box is provided so as to be partitioned into a plurality of regions, and the internal space is opened more than when the combined state of the two box structures is released to open the internal space. Equipped with a box-side cutting part (box-side cutting part 151 etc.) formed so as to be easy to cut,
When the box-side cutting part is cut and a part of the defining part is removed from the position defining the internal space, the element is removed or at least the element is mounted on the control board The game machine according to any one of the means 1 to 11, wherein an opening (opening 154 or the like) that allows removal of the board is formed in the substrate box.

  According to the means 12, the box side cut portion is formed in the substrate box, and when the box side cut portion is cut, a part of the defining portion is removed 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 easier to cut than when the combined state of the box structure is released, when the above elements are taken out from the board box and carefully inspected at the game hall, the work is performed. It can be done relatively easily. In particular, when the coupling means is accommodated in the internal space of the substrate box, it is difficult to perform an unauthorized release of the coupled state, but it is difficult to inspect the control substrate and elements. Providing a portion that can be easily cut positively as described above makes it possible to achieve both improvement in crime prevention and guarantee of workability.

  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 fixing the body, there is no need to consider workability when opening the internal space of the substrate box. Therefore, it is possible to firmly fix the plurality of box structures.

  It should be noted that the “defining part that defines the internal space of the substrate box” may be a part or all of the substrate box. In other words, it may be “a peripheral wall that defines the internal space of the substrate box” or “a wall portion that defines the internal space of the substrate box in the substrate box”. The “partition wall” and the “defining part” shown in the means 11 may indicate the same object or may indicate different objects.

  In addition, the “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.

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

  Means 13. The gaming machine according to claim 12, wherein the box side cutting portion is formed so as to partition an area including a portion facing the element in the defining portion with respect to a surrounding area.

  According to the means 13, by cutting the box side cutting part, it is possible to expose the region where the element is mounted on the control board. 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 14. 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. 12 or means 13 gaming machine.

  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 12 or 13, characterized in that:

  Means 15. The gaming machine according to any one of means 12 to means 14, wherein the coupling means is provided in an area other than an area partitioned by the box-side cutting portion.

  According to the means 15, even when the box side cutting part is cut and a part of the defining part is removed, the joined state of the first box structure and the second box structure by the joining means is maintained. The Thereby, unnecessary exposure of the control board can be suppressed. In particular, in combination with the means 14, it is possible to suitably suppress the removal of the control board by separating the box structural bodies.

Means 16. The control board is provided so as to divide the control board into a plurality of regions, and includes a board-side cutting part (board-side cutting part 161) that is easier to cut than other parts of the control board,
By cutting the substrate-side cutting part, the area on which the element is mounted on the control board can be separated from other areas,
The area in which the element is mounted is set to a size that can be taken out from the substrate box through an opening formed in the substrate box by cutting the box-side cutting portion. The gaming machine according to means 15.

  In the configuration in which the configuration of the above means 14 is provided and the control board cannot be removed even if the box-side cutting section is cut, the area where the element is mounted for inspecting the control board is placed outside the board box. May need to be removed. In this case, according to the means 4, the substrate side cutting part is formed in the control board, and the area where the element is mounted on the control board is taken out of the substrate box by cutting the board side cutting part. be able to. And the board | substrate side cutting part is formed easily compared with the other area | region in a control board. Therefore, the workability of the inspection can be improved.

  Means 17. The box-side cutting portion is formed so as to divide a region including the entire portion facing the substrate-side cutting portion in the defining portion with respect to a surrounding region. The gaming machine described in 1.

The back side structure 101, the front side structure 102, and the connector plate 104 are transparent so that the element mounting surface 97 and the solder surface 98 of the main control board 91 accommodated in the board box 92 can be seen from outside the board box 92. It is made of a material having properties. 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 back-side flat plate 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 back flat plate portion 111. The back side flat plate 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. In addition, on the side of the back side flat plate portion 111 facing the main control board 91, a partition frame portion 113 that partitions the plate surface into a square shape is integrally formed. The partition frame portion 113 protrudes from the back side flat plate portion 111 to the main control board 91 side.

  As shown in FIG. 8, a plurality of bosses 114, 115, 116 are integrally formed on the back side flat plate portion 111 on the inside and outside of the region partitioned by the partition frame portion 113. Each is formed with a screw hole. Among these bosses 114 to 116, the boss 114 formed in the region partitioned by the partition frame portion 113, specifically, the boss 114 formed along the peripheral edge of the partition region, the main control board 91 is connected to the back side structure 101. The other bosses 115 in the region partitioned by the partition frame portion 113 are used for temporarily fixing the main control board 91 and are partitioned by the partition frame portion 113. The boss 116 formed outside the formed region is used for temporarily fixing the front side structure 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 is overlapped with the partition frame portion 113 of the back side structure 101, and the solder surface 98 of the main control board 91 is opposed to the area partitioned by the partition frame portion 113 in the back side flat plate portion 111. Yes. In this case, a closed space may be formed between the main control board 91 and the back side flat plate part 111 by bringing the peripheral edge of the main control board 91 and the partition frame part 113 into contact with each other. You may make it provide a clearance over the perimeter.

  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 back side peripheral wall portion 118 that stands on the main control board 91 side and surrounds the main control board 91 is integrally formed over the entire outer peripheral edge of the back side flat plate portion 111. The back-side peripheral wall portion 118 is formed by connecting four plate-like portions corresponding to the respective edges of the back-side flat plate 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 back side flat plate part 111 and the back side peripheral wall part 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 connector plate 104 is 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 back side flat plate part 111 of the back side structure 101 and the front side wall part 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 back side flat plate 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, the front side peripheral wall part 122 is formed by connecting four plate-like parts corresponding to the respective edges of the front side wall part 121, and each of these plate-like parts has a substantially constant thickness. doing. By these front side wall part 121 and front side peripheral wall part 122, the front side structure 102 has a substantially box-like structure released to 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.

  A shielding portion 124 that covers the boundary between the peripheral wall portions 118 and 122 from the inside is integrally formed with the back side structure 101. More specifically, the shielding part 124 is formed along the inner peripheral edge of the back side peripheral wall part 118, and the outer surface of the shielding part 124 is in contact with the inner surface of the front side peripheral wall part 122 in the entire region. That is, in a state where both the constituent members 101 and 102 are fixed, the boundary portion between both the peripheral wall portions 118 and 122 is closed from the inside. Further, the shielding part 124 defines the relative movement direction of the two structural members 101 and 102 when the two structural members 101 and 102 are assembled to a predetermined direction (the surface direction of the element mounting surface 97 in the present embodiment). It has both a function as a means and a function as a suppressing means for suppressing the positional deviation between the two structural members 101 and 102 after the assembly is completed. When assembling both the constituent members 101 and 102, the inner surface of the front peripheral wall portion 122 is aligned with the outer surface of the shielding portion 124, so that the predetermined direction (the surface direction of the element mounting surface 97 in the present embodiment) is directed. Assembling guidance is given. In other words, the assembly from directions other than the predetermined direction is restricted. In this way, assembling is guided, the end surfaces 119 and 123 of the peripheral wall portions 118 and 122 are guided to the assembling completion positions, and the assembling of the two structural members 101 and 102 is completed. In a state where the two structural bodies 101 and 102 are assembled to each other, the outer surface of the shielding portion 124 is in contact with the inner surface of the front peripheral wall portion 122, so that the direction intersects the predetermined direction. Can be suppressed. Note that the “defining means” can also be referred to as “guidance means” when attention is paid to the fact that guidance to a predetermined assembling completion position is performed when assembling both the structural members 101 and 102.

  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.

  As described above, the front side structure 102 in which the connector plate 104 is integrated covers the element mounting surface 97 of the main control board 91 with respect to the back side structure 101 in which the main control board 91 is integrated. It is combined. 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.

  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 connector plate 104 is integrated, and the entire solder surface 98 of the main control board 91 is the back side. It faces the 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. 12 is an explanatory diagram showing a partially enlarged front view of the substrate box 92 for explaining the easy opening structure. FIGS. 11 and 12 are explanatory diagrams for explaining the easy opening 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.

  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.

  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 (specifically, the CPU chip 93) of the main control board 91 is exposed. When the CPU chip 93 is exposed, the CPU chip 93 can be removed from the main control board 91.

  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 is 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. 10, 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 is 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. 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. 10, the substrate-side removal region 163 is formed so as to be included in the range of the projected region when the box-side removal region 153 is projected onto the main control substrate 91 side. . 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. In this state, by cutting the substrate side cutting portion 161, the substrate side removal region 163 can be taken out through the opening 154 formed in the substrate box 92 by removing the box side removal region 153. 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. 10, the wiring pattern 164 on at least the element mounting surface 97 side of the main control board 91 is such that a part of the wiring 165 constituting the wiring pattern 164 straddles the board-side cutting portion 161. Is formed. 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 and the main control board 91 are taken out from the board box 92 in order to perform inspection at the game hall. FIG. 13 is an explanatory diagram for explaining the operation when the CPU chip 93 and the main control board 91 are taken out from the board box 92.

  First, a case where the CPU chip 93 is inspected in the game hall will be described. First, as shown in FIG. 13A, the main control device 63 is taken out from the gaming machine main body 12. 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 board box 92 is opened, and the element mounting surface 97 of the main control board 91 is exposed, and the CPU chip 93 can be accessed (physical contact). Since the CPU chip 93 is not soldered to the main control board 91 as described above, the CPU chip 93 can be easily removed by pulling the CPU chip 93 in the direction facing the element mounting surface 97. Thereby, the inspection of the CPU chip 93 can be performed carefully.

  Next, a description will be given of the operation when the substrate-side removal region 163 of the main control substrate 91 is taken out from the substrate box 92. As shown in FIG. 13B, after the box side cutting portion 151 of the front side structure 102 is cut to remove the box side removal region 153, 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 part 161 can be cut using a tool for cutting the box side cutting part 151, the work of taking out the substrate side removal region 163 can be performed relatively easily.

  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 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 disposed at the original position of the substrate box 92. 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 box-side removal region 153 and cutting the substrate-side cutting portion 161 to take out the substrate-side removal region 163, the substrate-side removal region 163 is disposed at the original position on the back-side 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 coupling means between the front side structural body 102 and the back side structural body 101, (1) an adhesive and (2) a coupling mechanism 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 above-described coupling mechanism 175 will be described with reference to FIGS. 14A is a partial cross-sectional view taken along line AA in FIG. 5, and FIG. 14B is an exploded perspective view showing the configuration of the coupling mechanism 175.

  The coupling mechanism 175 is constituted by a pair of coupling bodies 176 and 177 accommodated in the internal space of the substrate box 92, and both the coupling bodies 176 and 177 are coupled to each other. The structure 102 is integrated. More specifically, the combined bodies 176 and 177 are combined based on the relative positions of the combined bodies 176 and 177 changing with the relative movement of the two constituent bodies 101 and 102 in the specified direction. It is configured to shift to a state.

  The combined bodies 176 and 177 are arranged separately on the back side structure 101 side and the front side structure 102 side. Hereinafter, for the convenience of explanation, the combination disposed on the back-side structure 101 side is referred to as “back-side combination 176”, and the combination disposed on the front-side structure 102 side is also referred to as “front-side combination 177”.

  As shown in FIG. 8, the back-side combined body 176 is accommodated in a region defined by the back-side flat plate portion 111 and the back-side peripheral wall portion 118 and is fixed to the inner surface of the back-side flat plate portion 111. The back side coupling bodies 176 are respectively arranged at the four corners of the area facing the front side wall part 121 in the back side flat plate part 111, specifically, the area partitioned by the partition frame part 113. The corners of the main control board 91 are notched so as to avoid interference with the back side combined body 176, and these back side combined bodies 176 are not obstructed by the main control board 91 and are not blocked by the front side wall portion 121. It is in a state of protruding toward.

  On the other hand, almost the entire front-side combined body 177 is accommodated in a region partitioned by the front-side wall portion 121 and the front-side peripheral wall portion 122 and is fixed to the inner surface of the front-side wall portion 121 (see FIG. 9). The front side combined body 177 is disposed at a portion facing the back side combined body 176 in the front side wall portion 121. More specifically, the front-side combined body 177 is disposed so as to overlap the back-side combined body 176 in the prescribed relative movement direction of the two structural bodies 101 and 102.

  Here, based on FIG. 14, each coupling body 176,177 will be described in detail. The back side combined body 176 includes a back side base portion 180 as an attachment portion for the back side flat plate portion 111. The back side base portion 180 has a plate shape parallel to the back side flat plate portion 111, and the plate surface of the back side base portion 180 is bonded to the back side flat plate portion 111 so that the back side structure 101 and the back side combined body 176 are fixed. That is, they are integrated. A columnar back side spacer portion 181 extending from the back side base portion 180 toward the front side wall portion 121 (specifically, the front side combined body 177) is integrally formed on the back side base portion 180. In other words, the central axis of the back side spacer 181 is set so as to face the same direction as the prescribed relative movement direction of the two structural members 101 and 102.

  In addition, the front-side combined body 177 includes a front-side base portion 190 as an attachment portion with respect to the front side wall portion 121, similarly to the back-side combined body 176. By bonding the front side base portion 190 to the back side flat plate portion 111, the back side structure 101 and the front side combined body 177 are fixed, that is, integrated. The front side base 190 is integrally formed with a columnar front side spacer 191 extending from the front side base 190 toward the back side spacer 181. The central axis of the front side spacer 191 is the same as the central axis of the back side spacer 181. It is set to overlap. The end surfaces of the spacer portions 181 and 191 are in contact with each other over the entire area. As described above, since the opposing back side flat plate part 111 and the joined bodies 176 and 177 provided on the front side wall part 121 are in contact with each other at their end faces, the joined side bodies 176 and 177 are in contact with the back side flat plate part 111. And the function as a support | pillar which supports the front side wall part 121 is provided. For convenience of explanation, the end surface of the back spacer portion 181 is also referred to as a back contact surface 182 and the end surface of the front spacer portion 191 is also referred to as a front contact surface 192.

  The front side coupling body 177 is insert-molded with a coupling metal 195 protruding from the front side contact surface 192, and the back side coupling body 176 is formed with a receiving portion 183 into which the coupling metal 195 is fitted. The coupling fitting 195 has a long plate-shaped main body portion 196 that straddles the boundary between both contact surfaces 182 and 192, and an inclined portion 197 that is cut and raised from the main body portion 196 with the distal end side of the main body portion 196 as a root. doing. More specifically, the main body portion 196 extends in the same direction as the prescribed relative movement direction, and the inclined portion 197 protrudes in a direction intersecting with the relative movement direction. The inclined portion 197 can be flexibly deformed (specifically elastically deformed) with the base portion as a base end, and the amount of protrusion of the inclined portion 197 from the main body 196 changes based on the deformation.

  The accommodating portion 183 is formed corresponding to the coupling fitting 195 and has a hole shape that is recessed from the back-side contact surface 182 toward the guide direction. More specifically, the accommodating part 183 is set so that the coupling fitting 195 with the inclined part 197 protruding therein can be accommodated therein. In addition, a stopper portion 184 that protrudes toward the inside of the opening edge and contacts the inclined portion 197 is formed at the opening edge of the housing portion 183. More specifically, the stopper portion 184 is formed on a predetermined portion of the opening edge of the housing portion 183, that is, on the same side as the side from which the inclined portion 197 protrudes, and the stopper portion 184 opens the opening of the housing portion 183. It is narrowed to such an extent that the passage of the main body 196 is allowed. Since the inclined portion 197 inserted into the housing portion 183 is hooked with the stopper portion 184 formed in this manner, both the coupled bodies 176 and 177 are coupled. The joined bodies 176 and 177 are formed of a transparent synthetic resin material except for the joined fitting 195, and the joined state from the outside of the joined bodies 176 and 177 (the hooked state of the joined fitting 195) is confirmed. It is possible.

  Further, as shown in FIG. 14 (a), the boundary portion B1 between the contact surfaces 182 and 192 in the combined bodies 176 and 177 is the boundary between the two structural bodies 101 and 102 (specifically, between the end surfaces 119 and 123). It is set at a position away from the extension of the part B2. Specifically, the back side spacer part 181 of the back side combined body 176 is located on the extension of the boundary part B2. For this reason, even if an unauthorized tool or the like is inserted through the boundary part B2, it is difficult to access the boundary part B1. Thereby, the inconvenience that the coupled state by the coupling metal fitting 195 is illegally released is less likely to occur.

  As shown in FIG. 14 (a), the protrusion amount L1 from the front-side contact surface 192 of the coupling fitting 195 is the guide stroke amount when the components 101 and 102 are combined, that is, the rear peripheral wall portion of the shielding portion 124. The standing amount L2 from 118 is set to be smaller. For this reason, when the two structural members 101 and 102 are combined, after the movement in the relative movement direction defined by the shielding portion 124 starts, the tip of the coupling fitting 195 is inserted into the housing portion 183. .

  Here, the assembling work of the board box 92 will be described with reference to FIG. FIG. 15 is a partial schematic view showing the state of assembling the two structural members 101 and 102. When assembling both the structural members 101 and 102, FIG. 15 (a) → FIG. 15 (b) → FIG. c) Work is performed in the order of FIG. 15 (d).

  As shown in FIG. 15A, when assembling the two structural members 101 and 102, the open parts of the structural members 101 and 102 are set to face each other. When bringing both components 101 and 102 close together, first, as shown in FIG. 15B, the inner surface of the front peripheral wall portion 122 of the front-side component 102 is brought into contact with the shielding portion 124 of the back-side component 101. . Then, by moving the front-side structure 102 along the shielding portion 124, assembly guidance is performed in a predetermined relative movement direction. Note that at the time when the assembly guidance is started, the combined bodies 176 and 177 are in a state of facing each other at a predetermined distance. In addition, since both the constituent members 101 and 102 are both transparent as described above, when the two constituent members 101 and 102 (specifically, the front peripheral wall portion 122 and the shielding portion 124) are aligned, the shielding portion 124 and the front side are aligned. The relative position with respect to the peripheral wall portion 122 is easily grasped visually, and the work efficiency is improved.

  When the components 101 and 102 are brought closer to each other in accordance with the assembling guide by the shielding portion 124, the distal end portion of the coupling fitting 195 is inserted into the housing portion 183. Thus, in the state where the relative movement direction is limited, the shielding part 124 and the front side peripheral wall part 122 are in contact with each other, and the positional variation in the direction intersecting with the assembly direction of both the structural members 101 and 102 is suppressed. In addition, it is suitably avoided that the distal end portion of the coupling fitting 195 hits a portion other than the housing portion 183.

  When both the constituent members 101 and 102 are brought close to a predetermined distance, as shown in FIG. 15C, the inclined portion 197 comes into contact with the stopper portion 184 and bends and deforms with its root portion as the base end (more specifically, elastic) Deform. As a result, the inclined portion 197 is folded with respect to the main body portion 196, that is, the protrusion from the main body portion 196 is suppressed, and the movement of the coupling fitting 195 to the inner side of the housing portion 183 is allowed. In such a state, the inclined portion 197 is biased toward the original protruding position.

  As shown in FIG. 15D, the end surfaces 119 and 123 of the constituent members 101 and 102 at which the two constituent members 101 and 102 reach the assembly completion position come into contact with each other. In synchronization with this, the inclined portion 197 is restored to its original state by its own elastic force in the accommodating portion 183. Then, the tip end portion of the inclined portion 197 is caught by the stopper portion 184. As a result, the two structural members 101 and 102 are transferred to the combined state, and the assembly work of the two structural members 101 and 102 is completed. As described above, after the assembly work is completed, access to both the combined bodies 176 and 177 is restricted, and the two structural bodies 101 and 102 cannot be separated.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 15, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The main control board 91 provided in the main controller 63 incorporates a main control circuit 202 and a power failure monitoring circuit 203.

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

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

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

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

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

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

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

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

  The coupling mechanism 175 (specifically, the coupling bodies 176 and 177) is accommodated in the internal space of the substrate box 92. Thereby, exposure of the coupling mechanism 175 to the outside of the substrate box 92 can be avoided, and access (physical contact) to the coupling mechanism 175 from the outside of the substrate box 92 can be made difficult. By making it difficult to access the combined bodies 176 and 177 in this way, it is difficult to release the combined state of the both structural bodies 101 and 102, and unauthorized removal of the main control board 91 and the CPU chip 93, etc. Can be suppressed.

  Paired coupling bodies 176 and 177 were arranged at the four corners of the substrate box 92. Accordingly, it is possible to suitably suppress the separation between the two structural members 101 and 102, that is, the spread of the boundary portion between the two structural members 101 and 102. By suppressing the spread of the boundary part in this way, it is possible to suitably suppress the inconvenience that an unauthorized tool or the like is inserted through the boundary part. Further, by arranging the corners of the substrate box 92, it is possible to easily avoid interference with the main control substrate 91. Therefore, coexistence with the main control board 91 is suitably realized in a limited area of the internal space of the board box 92.

  Based on the assembling work of both the constituent members 101 and 102, the connecting members 176 and 177 are connected to each other. That is, a predetermined assembling direction is set for both the structural members 101 and 102, and a predetermined working direction is set for the coupling of the combined bodies 176 and 177 so that these directions are the same. Thereby, the assembling work of both the constituent members 101 and 102 and the joining work of the joined bodies 176 and 177 can be integrated, and the work is simplified. In the present embodiment, in particular, since the coupling bodies 176 and 177 are accommodated in the internal space of the substrate box 92, it is assumed that it is difficult to manually couple the coupling bodies 176 and 177. If it is attempted to perform the assembly work of the two structural members 101 and 102 and the joint work of the two combined bodies 176 and 177 in parallel, the work is considered to be complicated. In this regard, as described above, the combined bodies 176 and 177 can be coupled with the assembly work of the two structural bodies 101 and 102, so that the work is not complicated and a practically preferable configuration is realized.

  In addition, if the joining operation is performed while visually confirming the joined bodies 176 and 177, the transition to the joined state may be incomplete due to the assembling variation of both the box constituent bodies. In this regard, in the present embodiment, the shielding portion 124 that constitutes the defining means guides the assembly positions of both the constituent members 101 and 102 to make it difficult for variations in position due to the assembly work to occur. That is, the coupled state can be realized without visually confirming the coupling work of the coupled bodies 176 and 177. Therefore, it is possible to make inconvenience that the transition to the coupled state is not performed due to work variation or the like.

  As described above, when a configuration including a plurality of sets of combined bodies 176 and 177 can be expected, improvement in crime prevention can be expected, but the work can be complicated due to the necessity of individual connection work. In this regard, in the present embodiment, as described above, the joining work of all the joined bodies 176 and 177 depends on the assembling work of both the constituent bodies 101 and 102, and it is not necessary to perform the joining work individually. . Therefore, it is possible to improve the crime prevention by adopting a configuration including a plurality of sets of combined bodies 176 and 177, and avoid the complicated assembly work due to the increase in the number of combined bodies 176 and 177. can do.

  Further, the shielding part 124 has a shielding function for closing the boundary portion between the two structural members 101 and 102 in addition to the function of assembling and guiding the structural members 101 and 102. For this reason, it is possible to suppress the occurrence of inconvenience such as insertion of an unauthorized tool or the like through the boundary portion between the two structural members 101 and 102. In addition, since the conjugates 176 and 177 are arranged apart from the boundary part and the shielding part 124 is disposed between the boundary part and the conjugates 176 and 177, the board box 92 can be illegally connected to the joint part. Is difficult to access.

  By connecting the spacer portions 181 and 191 of the combined bodies 176 and 177 via the contact surfaces 182 and 192, the front side wall portion 121 and the back side flat plate portion 111 are connected. That is, the combined bodies 176 and 177 are provided with a function as a support portion that supports the front side wall portion 121 and the back side flat plate portion 111. By these combined bodies 176 and 177, the bending of the front side wall part 121 and the back side flat plate part 111 is suppressed, and the boundary between the constituent bodies 101 and 102 is expanded by the bending of the front side wall part 121 and the back side flat plate part 111. Inconvenience is less likely to occur. In particular, the combined bodies 176, 177 can support the front side wall 121 and the back side flat plate 111 at a position closer to the center of the main control board 91 than the peripheral walls 118, 122. A support function can be suitably exhibited.

  The inclined portion 197 and the stopper portion 184 of the coupling fitting 195 are accommodated in a closed space defined inside the spacer portions 181 and 191. For this reason, even if an unauthorized tool is inserted from the boundary part between the two structural members 101 and 102, it is difficult to access the joint parts 176 and 177. As a result, the inconvenience that the coupled state is illegally released can be suitably avoided.

  The coupling sites of both coupling bodies 176 and 177 are arranged on the element mounting surface 97 side of the main control board 91. Thereby, even if the main control device 63 is in a state where it is mounted on the gaming machine main body 12, it is possible to easily check the binding site. For this reason, if the coupling fitting 195 or the like is deformed or damaged due to unauthorized opening or the like, it is possible to easily grasp such an unfair fact and contribute to improvement of crime prevention.

  By arranging the combined bodies 176 and 177 in the internal space of the substrate box 92, it is difficult to check the combined state of the combined bodies 176 and 177. In this respect, in this embodiment, not only the two structural members 101 and 102 but also the combined bodies 176 and 177 (excluding the connecting metal fitting 195) are formed of a transparent material, thereby ensuring visibility. It has become.

  After the guide for assembling the two structural members 101 and 102 by the shielding part 124 is started, the coupling fitting 195 is inserted into the housing part 183. For this reason, it is preferably avoided that the fitting 195 hits a part other than the housing portion 183 and is deformed. Therefore, due to the deformation of the coupling fitting 195 and the like, it is difficult to cause inconvenience that the coupling function of the coupling bodies 176 and 177 is impaired.

  The spacer portions 181 and 191 of the combined bodies 176 and 177 have a cylindrical shape. For this reason, even if an unauthorized tool is inserted from the boundary portion between the two structural members 101 and 102 and the combined bodies 176 and 177 are pushed by the unauthorized tool, the unauthorized tool remains on the surfaces of the spacer portions 181 and 191. It is easy to escape along (is easy to escape). As a result, by pressing and deforming the bonded bodies 176 and 177, it is possible to make it difficult to cause inconveniences such as easy access to the binding site, and it is possible to contribute to further improvement of crime prevention.

  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 back-side combined body 176 and the front-side combined body 177 are accommodated in the internal space of the substrate box 92, so that the combined bodies 176 and 177 are not easily disconnected. It has been broken. And the positive weak part for canceling | releasing fixation of both the structural bodies 101 and 102 by both the coupling bodies 176 and 177 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. 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.

  In addition, it is not limited to the description content of each embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (A) In the above embodiment, the substrate box 92 is formed using the two structural bodies 101 and 102 that cover the main control board 91 from the front side and the back side, but the present invention is not limited to this. For example, the substrate box may be formed using two components that cover the main control board 91 from both sides in the longitudinal direction of the main control board 91 or both sides in the short side direction.

  In addition, although both the back side structure 101 and the front side structure 102 have a box shape that is released toward the opposite side (the main control board 91 side), the structure is not necessarily limited thereto. . One of the back side structural body 101 and the front side structural body 102 may be configured to have a plate shape that closes the other open portion.

  (B) In the above embodiment, the adhesive is used as the fixing means for fixing the combined bodies 176 and 177 to the respective constituent bodies 101 and 102. However, this is changed and the fasteners such as screws are used. Also good. Desirably, a break screw similar to the break screw 117 described above, a known one-way screw, or the like may be used. Thereby, unauthorized removal of the combined bodies 176 and 177 can be suppressed.

  Further, the combined bodies 176 and 177 are formed separately from the respective structural bodies 101 and 102, and both are fixed by fixing means (specifically, an adhesive). It is good also as a structure which integrally forms 177 and each structure 101,102.

  (C) In the above-described embodiment, the back plate portion 111 and the front side wall portion 121 that are opposed to each other are coupled by the coupling bodies 176 and 177. However, the present invention is not limited to this. For example, the back side flat plate part 111 and the front side peripheral wall part 122 may be combined, or the front side wall part 121 and the back side peripheral wall part 118 may be connected. Further, as shown in FIG. 17A, coupling portions 256 and 257 projecting inward of the substrate box 255 are respectively provided on the back side peripheral wall portion 252 of the back side structure 251 and the front side peripheral wall portion 254 of the front side structure 253. The peripheral wall portions 252 and 254 may be coupled to each other through the coupling portions 256 and 257.

  (D) In the above embodiment, the boundary part B1 between the two combined bodies 176 and 177 is separated from the extension of the boundary part B2 between the two structural bodies 101 and 102. More specifically, although the boundary part B1 between the two combined bodies 176 and 177 is arranged in the region partitioned by the front side structure 102, it can be changed as follows. That is, it is also possible to arrange the boundary part B1 between the two combined bodies 176 and 177 in the region partitioned by the back side structure 101.

  Further, as shown in FIG. 17B, the rising amounts of the spacer portions 263 and 264 of the back side combined bodies 261 and 262 are different, and the rising amounts of the spacer portions 267 and 268 of the front side combined bodies 265 and 266 are different. It is also possible. In this way, by making the standing amounts different from each other, the boundary portion of the combined bodies 261 and 262 and the boundary portion of the combined bodies 265 and 266 can be shifted from each other in the prescribed relative movement direction. Thus, if the boundary part exists at a shifted position, the combined bodies 261 and 262 and the combined bodies 265 and 266 come into contact in different combinations when the components 269 and 270 are assembled incorrectly. Both structural members 269 and 270 are prevented from reaching the assembly completion position. Thus, by avoiding wrong assembly, contact between the connector, various elements, and the front-side structure 270 can be suitably suppressed. That is, by making a configuration in which the boundary portions of the combined bodies 261, 262, 265, and 266 are shifted, it is possible to impart an erroneous assembly prevention function to the combined bodies 261, 262, 265, and 266.

  Moreover, in the said embodiment, although it was set as the structure which attaches the coupling metal fitting 195 to the front side coupling body 177 side, it is good also as a structure which attaches the coupling metal fitting 195 to the back side coupling body 176 side. For example, as shown in FIG. 17B, the coupling fitting 271 may be mounted on the front side coupling body 265 side, and the coupling bracket 272 may be mounted on the back side coupling body 262 side.

  It should be noted that a portion corresponding to the coupling fitting 195 can be integrally formed with the front side coupling body 177. However, in such a case, there is a concern that the visibility of the binding site may be reduced. Therefore, it is preferable to distinguish the stopper portion 184 and the inclined portion 197 by making the colors of the binding bodies 176 and 177 different.

  (E) In the above-described embodiment, each of the constituent bodies 101 and 102 is connected using the four sets of connecting bodies 176 and 177, but the number is not limited to four sets. However, when the two structural members 101 and 102 are coupled within a limited space in the substrate box 92, the separation of the boundaries between the structural members 101 and 102 is preferably performed without hindering the removal of the main control board 91. It is important to suppress. As shown in the above-described embodiment, when the boundary between the two structural bodies 101 and 102 is substantially rectangular, interference with the main control board 91 is suppressed by arranging a combined body at each corner of the boundary. However, it is possible to easily suppress the separation of the boundary. Therefore, it is desirable to use four sets of combinations corresponding respectively to the four corners of the boundary.

  (F) In the above-described embodiment, the shielding portion 124 has a structure having a guide function when the two structural members 101 and 102 are combined. However, it is possible to change this and separately form a part having the guide function. is there. Further, such a guidance function can be given to the combined bodies 176 and 177. A specific example will be described below with reference to FIG.

  In the above-described embodiment, the front-side combined body 177 has a substantially columnar shape. However, this is changed so that the front-side combined body 280 has a cylindrical shape. On the other hand, the back side combined body 281 is formed in a columnar shape accommodated in the front side combined body 280. More specifically: The outer diameter of the back side bonded body 281 is set to be substantially the same as the inner diameter of the front side bonded body 280. When combining the two structural bodies 282 and 283, the back-side combined body 281 is accommodated in the front-side combined body 280, so that both the structural bodies 282 and 283 are guided to the assembly completion position. Specifically, the two structural bodies 282 and 283 move relative to each other while the inner peripheral surface of the front-side combined body 280 and the outer peripheral surface of the back-side combined body 281 are in contact with each other, thereby guiding the assembly completion positions of both the structural bodies 282 and 283. Is done. Further, the back-side combined body 281 is provided with a locking piece 284 that protrudes from the outer peripheral surface of the back-side combined body 281 to the front-side combined body 280 instead of the connection fitting 195. The locking piece 284 is mounted in a state in which the back side combined body 281 is allowed to move in the radial direction, and is always biased toward the protruding side by a biasing member (not shown). On the other hand, an opening 285 into which the locking piece 284 is fitted is formed in the front-side combined body 280, and the combined state of both the combined bodies 280 and 281 is realized by hooking the locking piece 284 and the opening 285. Has been. The locking piece 284 has an inclined surface 286 formed so that the amount of standing gradually decreases from the base side to the tip side of the back-side combined body 281, and the two structural bodies 282 and 283 are combined. In addition, when the inclined surface 286 hits the tip edge of the front-side combined body 280, the locking piece 284 is pushed inward of the back-side combined body 281. Thereby, the protruding amount of the locking piece 284 is reduced, and the back side combined body 281 can move inside the front side combined body 280. When the two structural bodies 282 and 283 reach the predetermined combination completion position, the locking piece 284 reaches the opening 285 and protrudes so as to fit into the opening 285 by the urging force of the urging member. This shifts to the above-described combined state.

  As described above in detail, it is also possible to give a guidance function to each combined body instead of the shielding portion 124. However, the shielding part 124 in the above embodiment has a shielding function for closing the boundary portion between the two structural members 101 and 102 in addition to the guiding function. Therefore, it is preferable to leave the shielding part 124, and if the shielding part 124 is left as such, it is preferable to perform the combined guidance of the two structural members 101 and 102 by the shielding part 124.

  (G) In the above-described embodiment, the spacer portions 181 and 191 of the combined bodies 176 and 177 have a cylindrical shape. However, a prismatic shape may be used. However, there is a concern that the following disadvantages are likely to occur when the prismatic shape is used. That is, if an unauthorized tool is inserted through the boundary portion between the structural bodies 101 and 102, it is assumed that it is difficult to deflect the external force when the unauthorized tool hits the spacer portions 181 and 191. Therefore, the spacer portions 181 and 191 are desirably cylindrical.

  (H) In the above embodiment, the substrate-side cutting portion 161 is formed on the main control substrate 91, and the substrate-side cutting portion 161 is cut to remove the main control substrate 91 (specifically, the substrate-side removal region 163). However, the main control board 91 may be removed by changing this and providing the coupling bodies 176 and 177 with a cutting portion and cutting the cutting portion. Hereinafter, a specific example thereof will be described with reference to FIG.

  In the above embodiment, the spacer portion 191 of the front-side combined body 177 has a series of columnar shapes. However, this is changed, and the spacer portion 292 of the front-side combined body 291 is formed on the tip side and the root side. The columnar portions 292a and 292b and the plate-shaped portions 292c connected to the columnar portions 292a and 292b form a substantially columnar shape as a whole. More specifically, the plate-like portion 292c is configured by a thin plate extending in the same direction as the axial direction of the columnar portions 292a and 292b, and is disposed on both sides of the axis. The plate portion 292c has a thickness that is sufficiently smaller than the radius of the columnar portions 292a and 292b, and the combined bodies 291 and 293 can be separated by cutting these plate portions 292c with a nipper or the like.

  Thus, the plate-like portion 292c serving as the cutting portion is formed in a plate shape extending in the axial direction, thereby contributing to facilitating the cutting operation while easily ensuring the support function of the front side wall portion 121 and the back side flat plate portion 111. It is possible. Note that the configuration described in detail above can also be applied to the back-side bonded body 293.

  In the case of making a change as described above, it is preferable to omit the adhesive that joins both components 101 and 102 and to change the breaking screw 117 for fixing the main control board 91 to a known removable screw. Thereby, by cutting the plate-shaped portion 292c, the two structural bodies 101 and 102 can be separated, and the main control board 91 is removed by removing the screws after the main control board 91 is exposed. be able to.

  (I) In the above embodiment, the combined bodies 176 and 177 are configured to have transparency, but it is also possible to employ a configuration that does not have transparency. However, if the joined body 176 having the housing portion 183 and the stopper portion 184 is configured not to be transparent, it is difficult to visually recognize the joint fitting 195, that is, visually recognize the joined state. Therefore, it is preferable that at least the combined body 176 has a transparent structure.

  (J) In the above embodiment, the coupling fitting 195 is accommodated in the spacer portions 181 and 191. However, the coupling fitting may be exposed to the outside of the spacer portions 181 and 191.

  (K) It is also possible to provide a release operation part for releasing the combined state of the combined bodies 176 and 177 in the internal space of the substrate box 92.
