Japanese Patent No. 3784264

  By the way, in recent years, a wiring board is extracted from a used table, etc., and a program, data, etc. stored in a ROM are falsified. Obtained a board case, and obtained a first case body, a second case body, and a caulking means constituting a board case for a gaming machine having no scratches by destroying one of the cases, and obtained a falsified wiring board. There are many fraudulent acts of assembling in a board case (so-called “Nikoichi”) and replacing illegal products assembled by diverting them with regular products on the pachinko parlor side. In order to prevent such an illegal act, it is most effective to create a board case for a gaming machine using a connecting member for preventing the first and second case bodies from being reused.

  However, although the board case for gaming machines described in Patent Document 1 is inserted with the distal end portion of the sealing member being inserted into the connection hole of the case main body, the case main body, the upper lid, and the sealing member are separately formed. Therefore, if there are two substrate cases, it is possible to reuse the sealing portion by destroying one case body. The same is true for the fixtures. Furthermore, a cover member that covers the keyhole of the cylinder lock can be obtained in the same manner. Therefore, in order to act illegally, it is only necessary to release the lock of the holder metal. Moreover, in the said patent document 1, since many members are used for fraud prevention, cost will go up and the operation | work will also become complicated.

  The present invention has been made in order to solve the above-described problems, and its purpose is to prevent fraud in the board case while having a simple structure, and it is difficult to duplicate the board case. It is an object of the present invention to provide a gaming machine board case and a gaming machine equipped with the same, which can detect an illegal act at an early stage even if it is performed, and can further reduce the manufacturing cost.

In order to solve the above problems, a board case for a gaming machine according to the present invention is overlapped with a first case body and the first case body, and is housed inside at a predetermined closed position in the overlapped state. Is a board case for a gaming machine having a second case body that cannot be contacted from the outside, and an attachment portion formed at a corresponding end portion of the first case body and the second case body in a stacked state A connecting member is provided to connect the first case body and the second case body so as to be separable from each other by a predetermined distance, and the connecting member is integrally formed in a band shape having a predetermined width length by two-color molding , One of the first case body and the second case body is integrally formed with a protruding wall portion that sandwiches the connecting member in the width direction, and the first case body and the second case body are closed. Connect in position Characterized in that the member is accommodated so as not to protrude from the inner between the protruding wall portion outwardly.

  In the board case for gaming machines of the present invention, since the connecting member is integrally formed with the first case body and the second case body by two-color molding, the adhesive strength is improved and the connection is made firmly. Even if the connecting member is forcibly peeled off, it is difficult to peel off the connecting member well, and even if it is peeled off, a mark remains on the mounting portion. Furthermore, since a trace remains even if it tries to cut | disconnect a connection member, it cannot use all the members of the 1st case body which comprises a substrate case, a 2nd case body, and a connection member. Moreover, even if a fraudulent act is performed, the trace of a fraudulent act remains by peeling and cutting | disconnection of a connecting member, and discovery is quick.

  Specifically, the connecting member may be formed of an elastic body that can be elastically deformed, and may be configured to change the position of the first case body and the second case body from the open state to the overlaid state.

  In this way, since the connecting member is formed of an elastic body such as rubber (elastomer), the bending member can be bent and deformed from the open state to the overlapped state, so that the connecting member can be arranged in a compact manner. .

  Moreover, it is good also as a structure by which the uneven | corrugated surface for attaching a connecting member is formed in the attachment part formed in a 1st case body, and the attachment part formed in a 2nd case body.

  Thus, since the uneven | corrugated surface is formed in the attaching part, the adhesive surface of a connection member, a 1st case body, and a 2nd case body can be enlarged. Further, it is difficult to peel off more cleanly than a flat surface. Furthermore, when the connecting member is peeled off, it is difficult to clean the adhesive surface compared to the flat surface. Further, when rubber (elastomer) or the like is used as the connecting member, rubber (elastomer) or the like remains as a trace, so that it is easy to detect even if it is fraudulent. Moreover, even if rubber is removed, it is difficult to apply new rubber from above, and even if it is applied, it is easy to peel off.

  Further, the connecting member is formed in a band shape having a predetermined width, and either one of the first case body and the second case body has a protruding wall portion that sandwiches the connecting member in the width direction. It is good also as a structure which is formed integrally and is accommodated so that a connection member may not protrude outside from the inner side between wall parts in the state which has a 1st case body and a 2nd case body in the obstruction | occlusion position.

  Thus, since the protruding wall part of the form which pinches | interposes elastic bodies, such as rubber | gum (elastomer) as a connection member, is provided in either one of the 1st, 2nd case bodies, the wall part is rubber | gum. Protects the rubber from unwanted tampering and prevents the rubber from being damaged during installation and transportation. Further, since the rubber also moves in the twisting direction, the wall portion serves as a guide for restricting twisting when the first case body and the second case body are rotated or slid relative to each other.

  In order to solve the above-described problems, a gaming machine of the present invention is characterized by including the gaming machine substrate case described above.

  According to this, by providing the gaming machine board case described above in the gaming machine, fraud can be effectively prevented, and the safety of the gaming machine can be improved simply and inexpensively.

  According to the present invention, while the structure is simple, it is possible to prevent fraudulent acts on the board case, and it is difficult to duplicate the board case, and even if fraudulent acts are detected, the fraudulent acts can be detected early. In addition, it is possible to provide a board case for a gaming machine that can reduce the manufacturing cost. Further, since such a gaming machine substrate case is provided, a useful gaming machine capable of improving safety can be provided.

It is formed in a strip shape having a rectangular opening 51. One end portion of each connecting member 50 is attached to the attachment portion 31 a 4 on the upper wall 31 a of the lid body 30, and the other end portion is attached to the attachment portion 41 a 4 on the bottom wall 41 a of the base body 40. Specifically, each connecting member 50 is integrated with the lid body 30 and the base body 40 in the secondary side molding step by two-color molding (different material molding) using the lid body 30 and the base body 40 as the primary side molded product. Molded.

  Next, an operation procedure for setting the caulking means 60 of the substrate case 20 configured as described above to the caulking state will be described with reference to FIGS.

  First, as shown in FIG. 5, the main control board PB is assembled inside the lid 30 in the open state with the mounting surface facing downward. The main control board PB is placed on the back surface of the upper wall 31a, the support protrusions 31a1 of the upper wall 31a, and the support pieces 32c1 of the bulging portion 32, and each connector P2 is inserted into the corresponding connector through hole 31a3. Then, the positioning through holes H1 are positioned and fixed by the mounting screws B1 in a state where the positioning through holes H1 are engaged with the corresponding positioning projections 31a2 (see FIG. 6).

  Next, as shown in FIGS. 12A, 13, and 18 </ b> A, the lid body 30 on which the main control board PB is assembled is overlaid on the base body 40. In this case, in accordance with the elastic bending deformation of the connecting members 50, 50, the bulging portion 32 of the lid 30 is on the upper side while the lid 30 and the base body 40 are kept within a predetermined interval. Then, the lid 30 rotates with the vicinity of the lower edge of the side wall 31d of the main body 31 as a rotation fulcrum so that the main body 31 is on the lower side (see FIG. 13B). The position where the lid 30 and the base body 40 overlap in this way is the overlapping position.

  Next, as shown in FIGS. 12B, 14, and 18 B, the lid body 30 and the base body 40 in the overlapping position are relatively slid, that is, with respect to the lid body 30. The base body 40 is slid leftward, or the lid 30 is slid rightward relative to the base body 40. Then, the engagement grooves 31b1 and 31c1 on the side walls 31b and 31c of the lid body 30 engage with the engagement pieces 41b1 and 41c1 on the side walls 41b and 41c of the base body 40 (see FIG. 14B), and further the lid When the sliding operation is performed until the engagement holes 31d1 in the side wall 31d of the body 30 and the engagement protrusions 41d1 in the side wall 41d of the base body 40 are engaged, the lid body 30 and the base body 40 are substantially closed. Up-and-down separation is prevented. In this way, the position where the main control board PB is enclosed (the position where contact cannot be made) between the lid body 30 and the base body 40 is the closed position.

  In this case, as the lid body 30 and the case body 40 move from the overlapping position to the closed position, the attachment portion 31a4 on the lid body 30 side and the attachment portion 41a4 on the base body 40 side gradually approach, The curvature of the arc presented by the intermediate portion of each connecting member 50 gradually increases (see FIGS. 13B and 14B). And even if it is a case where the cover body 30 and the case body 40 are located in any of the overlapping position or the closed position, each connecting member 50 is accommodated without protruding from the inside between the guide walls 33 to the outside. The total length of each connecting member 50 and the protruding length of the guide wall 33 are set.

  As described above, since the connecting member 50 is formed of an elastic body, the connecting member 50 can be arranged in a compact manner because bending can be performed by increasing the curvature from the open state to the overlapping position. Furthermore, it is possible to slide (change the position) from the overlapping position to the closed position with a margin.

  In the closed position, the caulking member 62 of the base body 40 is accommodated in the caulking case 61 of the lid 30 as shown in FIGS. 14 (a), 14 (b), and 18 (b). Specifically, the side plates 62 a and 62 b of the caulking member 62 enter the corresponding gap D in the caulking case 61, the shelf-like plate 62 e of the caulking member 62 enters the region S 1 of the caulking case 61, and the caulking member 62. The shelf-like plate 62f enters the area S2 of the caulking case 61 (see FIG. 8).

  That is, the partition wall 61f of the caulking case 61 is in a positional relationship to be accommodated between the shelf-like plates 62e and 62f of the caulking member 62, and the caulking tool 62d of the caulking member 62 passes through the insertion hole 62e1 of the shelf-like plate 62e. It becomes possible to reach the caulking hole 61f1. In this accommodated state, the mark 62c3 provided on the movable plate 62c can be viewed from the work hole 61b1 in the side wall 61b of the caulking case 61 as shown in FIGS. 12 (b) and 14 (a). .

  With the lid 30 and the base body 40 in the closed position, using a mark 62c3 on the movable plate 62c of the caulking member 62 as a mark, for example, a tool such as a screwdriver is inserted into the work hole 61b1 of the caulking case 61 and a predetermined pressing force is applied. When the movable plate 62c is pushed in, the bridging portions 62c1 and 62c2 are cut, so that the tip of the movable plate 62c can move downward. Note that the movable plate 62c may be pushed in after the bridging portions 62c1 and 62c2 have been previously cut with a tool (such as a nipper).

  That is, as shown in FIGS. 15 and 18C, the distal end portion of the movable plate 62c moves downward by bending deformation with the intermediate portion on the base end side as an elastic deformation fulcrum. As a result, the caulking portion 62d1 of the caulking tool 62d is forcibly inserted into the caulking hole 61f1 of the partition wall 61f while being guided by the guide hole wall 62e0, and cannot be detached from the partition wall 61f (FIG. 3, FIG. 3). 4). In this caulking state, the lid body 30 and the base body 40 are in a fixed holding state, and the lid body 30 and the base body 40 cannot be slid from the closed position toward the overlapping position.

  Next, an operation procedure for releasing the fixed holding state between the lid 30 and the base body 40 will be described with reference to FIGS. 16, 17, and 18 (d).

  In this case, the bridging portions 63 and 63 of the caulking case 61 are cut using a tool such as a nipper. Thereby, since the lid 30 can be separated independently from the caulking means 60 in the caulking state, the fixed holding state between the lid 30 and the base body 40 can be released.

  As is clear from the above description, in the first embodiment, the caulking tool 62d (locking claw) is integrally connected to the base body 40 (first case body) via the movable plate 62c (connecting arm). Even after the caulking state, the connected state of the caulking tool 62d and the base body 40 is maintained. Therefore, when the caulking tool 62d is pushed toward the caulking hole 61f1 (locking hole), the movable plate 62c serves to guide the caulking tool 62d toward the caulking hole 61f1 with the base end portion as an elastic deformation fulcrum. Thus, the caulking tool 62d can be easily engaged with the caulking hole 61f1, and the workability during assembly can be improved.

  In the first embodiment, before the caulking state is established, the movable plate 62c is integrally connected to the base body 40 by the bridging portions 62c1 and 62c2 (first bridging portions), and the bridging portions 62c1 and 62c2 are cut. Thus, the movable plate 62c is in a cantilever state supported by the base body 40 on the base end side, and the movement of the caulking tool 62d toward the caulking hole 61f1 is allowed.

  As a result, the bridging portions 62c1 and 62c2 can be cut and caulked (the caulking tool 62d is pushed in) at the same time. However, since the movable plate 62c is connected (supported) to the base body 40 at the base end portion, the bridging portion 62c1. 62c2 can be cut with a tool (such as a nipper) in advance. Accordingly, since it is not necessary to push the caulking tool 62d toward the caulking hole 61f1 with a strong force, the caulking tool 62d can be caulked with respect to the caulking hole 61f1 almost certainly, and the work efficiency at the time of assembly can be improved. it can.

  In the first embodiment, the caulking case 61 (engaged portion) having the caulking hole 61f1 is integrally connected to the lid body 30 (second case body) by the bridging portions 63 and 63 (second bridging portion). By cutting the bridging portions 63, 63, the lid 30 can be separated independently from the caulking means 60 in the caulking state, and the fixed holding state of the lid 30 and the base body 40 is released. That is, the caulking tool 62d and the caulking hole 61f1 are left in the base body 40 in a state where the caulking tool 62d and the caulking hole 61f1 are caulked, and the lid body 30 and the base body 40 can be relatively slid from the closed position toward the overlapping position. it can.

  Thus, by cutting the bridging portions 63, 63, the fixed holding state of the lid body 30 and the base body 40 is released, but the bridging portions 63, 63 are not independent members, so the conventional opening trouble It is possible to prevent generation of dust such as a part.

  Further, in the first embodiment, since the movable plate 62c constituting the caulking member 62 is formed wide, the caulking case 61 is partitioned without the caulking tool 62 being swayed in the left-right direction when the movable plate 62c is bent and deformed. It can guide toward the caulking hole 61f1 in the wall 61f. Thereby, even if the method of applying the force for pressing the movable plate 62c is slightly deviated from the mark 62c3, the caulking state can be achieved almost certainly.

  Further, in the first embodiment, the caulking tool 62d is formed in a tapered shape, and the lid 30 and the base body 40 are closed by forcibly inserting the caulking tool 62d into the caulking hole 61f1. The base body 40 is formed with a guide hole 62e1 in the vicinity of the tip of the caulking tool 62d, which forms a guide hole wall 62e0 for guiding the caulking tool 62d to the caulking hole 61f1.

  As a result, the caulking tool 62d is guided toward the caulking hole 61f1 by the guide hole wall 62e0, so that the caulking work is further facilitated. Even if the lid 30 and the base body 40 are forcibly slid open, the caulking tool 62d is restricted from moving in the left-right direction by the guide hole walls 62e0 and 62f0 positioned above and below the caulking hole 61f1. The caulking tool 62d can be stably disposed with respect to the caulking hole 61f1.

Moreover, in the said Example 1, the cover body 30, the base body 40, and the connection members 50 and 50 are integrally molded by two-color molding, and each connection member 50 is accommodated between the guide walls 33 and 33. FIG. . Thereby, even if it is going to duplicate the substrate case 20 for the purpose of fraud, since the lid body 30 and the base body 40 are connected (integrated) by the connecting members 50 and 50, for example, the lid body 30 is destroyed. By securing the base body 40 without any scratches and conversely destroying the base body 40 and securing the lid body 30 without any scratches, forgery of the substrate case 20 can be suppressed and prevented.
Furthermore, even if it is going to cut | disconnect the connection members 50 and 50, since the guide walls 33 and 33 play the role which blocks cutting work, generation | occurrence | production of an improper act can be suppressed effectively. Since the connecting member 50 is made of an elastic body such as rubber, the connecting member 50 may move in the twisting direction. However, since the guide walls 33 are provided, the movement of the connecting member 50 can be restricted.

  Moreover, since each attachment part 31a4 and 41a4 for attaching the connection members 50 and 50 to the cover body 30 and the base body 40 are formed in sawtooth shape, the connection member 50, compared with the case where an attachment surface is a plane. The contact area with 50 can be increased, and the adhesive strength can be improved. Furthermore, in this case, even if the connecting members 50, 50 are peeled off from the respective attachment portions 31a4, 41a4 for the purpose of fraud, part of the connection members 50, 50 is likely to remain on the respective attachment portions 31a4, 41a4. Even if the connecting members 50, 50 are pasted again, they cannot be neatly pasted, are easily peeled off, and illegal acts can be prevented. In addition, it is possible to quickly find out the occurrence of fraudulent activity using the remaining portions of the connecting members 50, 50 in the attachment portions 31a4, 41a4 as traces.

  Further, since the opening 51 is formed in the connecting members 50, 50, the inside of the substrate case 20 can be visually recognized through the opening 51. Accordingly, the connecting members 50 and 50 are not limited to transparent ones, and opaque ones can be used. Furthermore, since the opening portion 51 allows a large degree of bending or twisting of the connecting member 50, workability when opening and closing the lid body 30 and the base body 40 is improved. The rubber and elastomer suitable for the material of the connecting members 50 and 50 have different elastic moduli depending on the type, but use the material of a desired material by appropriately setting the shape and size of the opening 51. can do. However, the opening 51 may not be formed depending on the material of the connecting members 50 and 50.

  Further, in the first embodiment, the caulking member 62 of the base body 40 is accommodated in the caulking case 61 of the lid body 30 in the closed position of the substrate case 20, and the partition wall 61f having the caulking hole 61f1 is the shelf-like plate 62e, It is accommodated in a narrow space between 62f. For this reason, after the caulking tool 62d and the caulking hole 61f1 are in the caulking state, it is extremely difficult to release the caulking state, and it is difficult to divert the parts. This can also effectively prevent the occurrence of fraud.

  In the first embodiment, the board case 20 described above is fixedly arranged on the back side of the game board 2 of the pachinko machine 1. Thereby, an illegal act can be prevented effectively and the safety | security of the pachinko machine 1 can be improved simply and cheaply.
