Further, the main board case 100 includes a case body member 50 that is attached to and detached from the back side of the game board 10 and a case lid member 60 that is detachably attached to the case body member 50. The main board assembly 30 is configured such that the case lid member 60 can be attached to the case body member 50 in a state where the main control board 31 is attached to the inner surface side of the case lid member 60. The main board assembly 30 is fixed to the main board mounting portions 15a and 15b by a left Nylatch (registered trademark) 36 attached to a left side fixing portion 58 extending outward from the left side portion of the case body member 50, and a case lid. A right Nylatch (registered trademark) 37 attached to a right side fixing part 68 extending outward from the right side part of the member 60 is used (see FIGS. 2 and 3).

  As shown in FIG. 4, the main control board 31 has an electronic component such as an electronic device 32 such as a built-in CPU and a connection connector 33 arranged on the left and right, with a ROM and a RAM disposed in the center. Composed. Substrate mounting holes 34 are formed at the four corners of the main control board 31. A base mounting screw 35 is inserted into the board mounting hole 34, and the board mounting portion 67 of the case lid member 60 shown in FIG. It is configured to be screwed and fastened.

  The case body member 50 has a short box-like shape having an opening on the rear side in a state where the main board case 100 is attached to the game board 10 and is made of a transparent resin such as ABS resin or polycarbonate (PC). The material is integrally molded by molding means such as injection molding. As shown in FIG. 4, reinforcing ribs 51 a are formed vertically and horizontally on the inner surface side bottom 51 of the case main body member 50 to improve the strength of the case main body member 50.

  A plurality of lid member mounting grooves 54 are formed in each of the main body member side wall portions (in FIG. 4, side wall portions extending rearward from the upper and lower edge portions of the bottom portion 51) 53, 53 of the case main body member 50. The lid member mounting groove 54 includes an insertion groove portion that opens rearward and on the inner surface side of the case body member 50, and a locking groove portion that extends to the left side and opens on the inner surface side of the case body member 50. When viewed from below or above, the main body member side wall 53 is formed as an L-shaped groove. Further, a lid member pressing wall 52 is formed to extend rearward from the bottom portion 51 in a plate shape so as to face each of the lid member mounting grooves 54 in parallel with the inner wall surface of the main body member side wall portion 53. The lateral width of the lid member pressing wall 52 is formed to be substantially the same as the lateral width of the lid member mounting groove 54. When viewed from above or below in the state of FIG. The wall 52 and the lid member mounting groove 54 are disposed so as to overlap.

  The case lid member 60 has a short box shape covering the opening of the case body member 50, and is integrally formed by a molding means such as injection molding using a transparent resin material such as ABS resin or polycarbonate (PC). Molded. As shown in FIG. 5, the side wall portion (lid member side wall portion) 66 extending forward from the upper and lower edges of the case lid member 60 has a locking projection protruding outward (vertical direction in FIG. 4). A plurality of 62 are formed. The locking projections 62 are formed in the same number as the lid member mounting groove 54 described above, and the arrangement interval thereof also corresponds to the lid member mounting groove 54. Further, on the inner side surface of the lid member side wall portion 66, a pressing projection portion 61 that protrudes inward corresponding to each locking projection portion 62 is formed. The pressing protrusion 61 is formed so as to deviate in the direction opposite to the sliding direction when the case lid member 60 is attached to the case body member 50 with respect to the locking protrusion 62.

  Therefore, when attaching the case lid member 60 to the case body member 50, the locking projection 62 is inserted into the insertion groove portion of the lid member attachment groove 54 from the rear in the state of FIG. By sliding and moving in the left-right direction (leftward in this embodiment) and inserting the locking projection 62 into the locking groove of the lid member mounting groove 54, the locking projection 62 and the lid member mounting groove 54 are moved. Fit.

  At this time, in a state where the locking projection 62 is inserted into the insertion groove of the lid member mounting groove 54, the pressing projection 61 is located on the right side of the lid member pressing wall 52. From this state, the case lid member 60 is moved. In a state where the case main body member 50 is slid leftward with respect to the case main body member 50 and the engaging protrusion 62 is inserted into the engaging groove portion of the lid member attaching groove portion 54, the outer surface of the lid member side wall portion 66 and the main body member side wall portion 53. The pressing projection 61 is sandwiched between the body member side wall 53 and the lid member pressing wall 52.

  When the case body member 50 and the case lid member 60 are configured as described above, the locking projection 62 is fitted into the lid member mounting groove 54 when the case lid member 60 is attached to the case body member 50. The case lid member 60 is restricted from moving backward with respect to the case body member 50 (movement for removing the case lid member 60 from the case body member 50). Further, since the lid member side wall portion 66 is pressed against and closely contacts the inner surface of the case body member 50 by the pressing protrusion 61 and the lid member pressing wall 52, the lid member side wall portion 66 can be pushed inward. Therefore, the locking projection 62 cannot be removed from the lid member mounting groove 54.

  As shown in FIGS. 5 and 6, the bottom of the inner surface of the case lid member 60 of the main board case 100 in which the main control board 31 is accommodated extends to both sides inside the lid member side wall 66 and prevents fraud. Ribs 80 are provided (in this embodiment, two fraud prevention ribs 80 are formed in parallel in the vertical direction). When the case lid member 60 is attached to the case body member 50 and the main control board 31 is accommodated in the case main body member 50, the fraud prevention rib 80 is replaced with the electronic device 32 disposed on the main control board 31. It is formed so as to be close to the surface of the electronic device 32 (the surface facing the bottom on the inner surface side of the case lid member 60) at a position corresponding to the target element to be performed.

  Further, as shown in FIGS. 5 to 7, the fraud prevention rib 80 has upper and lower ends attached to both side portions on the inner side of the lid member side wall portion 66, and is substantially the same as the vertical length of the case lid member 60. It is. Furthermore, the end on the main control board 31 side is formed in a concave shape so as to correspond to the shape of the electronic device 32 (the shape of the rear side surface and its both side faces in the state of being disposed on the main control board 31). When the case lid member 60 is attached to the case body member 50, the electronic device 32 (the surface and its side surface) and the main control board 31 (the surface on which the electronic device 32 is disposed) are close (for example, 0 to 2 mm). It is formed so as to be held at a certain degree.

  The fraud prevention rib 80 is integrated with the case lid member 60 by a molding means such as injection molding using a transparent resin material such as ABS resin or polycarbonate (PC) in the same manner as the case body member 50 and the case lid member 60. Molded. Therefore, the notation contents (company name, serial number, etc.) of the notation part 32a described on the surface of the electronic device 32 can be visually recognized, and the electronic device 32 should be illegally controlled by an unauthorized player by other unauthorized control elements. This fraudulent fact can be found in the case where it is exchanged.

  A body-side temporary fixing portion 55 is formed at the left end portion of the case main body member 50, and a lid-side temporary fixing portion 63 is formed at the left end side of the case lid member 60. When the case lid member 60 is attached to the case body member 50, that is, when the case lid member 60 is slid and attached to the case body member 50 in the left direction, these body side temporary fixing portions 55 are attached. And the lid-side temporary fixing portion 63 are engaged with each other, and the case lid member 60 is restricted from sliding to the right with respect to the case body member 50. Note that the case body member 50 and the case lid member 60 are thinly formed of a resin material as described above, and can be easily bent. Therefore, by bending the left end side of the lid side temporary fixing part 63 away from the main body side temporary fixing part 55, the engagement between the main body side temporary fixing part 55 and the lid side temporary fixing part 63 is released, and the case body The case lid member 60 can be removed from the case body member 50 by sliding the case lid member 60 to the right with respect to the member 50.

  In this way, the main board case 100 in which the main control board 31 is accommodated is divided into the case main body member 50 and the case lid member 60 that can be separated from each other, thereby attaching the main control board 31 to the case lid member 60. At this time, since the opening of the case lid member 60 can be mounted on a work desk or the like with the opening facing upward, the mounting work is facilitated and the assembly work efficiency is improved. Also, when attaching the case lid member 60 to the case main body member 50, the case lid member 60 can be attached only by sliding movement, so this operation is also easy. Further, when the case lid member 60 is slid and attached to the case body member 50 in this way, the lid member attachment groove 54 is formed on the case body member 50 side, and the locking projection 62 is formed on the case lid member 60. Since the mounting structure can be formed by forming, the structure of the main board case 100 can be simplified.

  As described above, since the main control board 31 is stored in the main board case 100 (the case main body member 50 and the case lid member 60), an illegal act on the main control board 31 can be prevented. However, when the case lid member 60 is attached to the case body member 50, the body side temporary fastening portion 55 and the lid side temporary fastening portion 63 are merely engaged, and the case body member It is easy to remove the case lid member 60 from 50. Therefore, in order to prevent the case lid member 60 in the closed state from slidingly moving with respect to the case body member 50 and preventing unauthorized operation, the main substrate case 100 of the main substrate assembly 30 is provided with an unauthorized opening prevention mechanism 70. ing.

  As shown in FIG. 4, the unauthorized opening prevention mechanism 70 can be cut to the four main body side engaging portions 56 integrally formed by connecting to the left end side of the case main body member 50 and the left end side of the case lid member 60. Four lid-side engaging portions 64 (connected to the lid-side engaging portion 64 from the case lid member 60) and the lid-side engaging portion 64, which are formed by being connected via a connecting portion 65. The case body member 50 includes four stopper members 71 for fixing and holding the case lid member 60.

  When the case lid member 60 is slid relative to the case main body member 50 so that the lid side engaging portion 64 overlaps the main body side engaging portion 56, the stopper member inserted into the lid side engaging portion 64 The engaging claw provided in 71 and the engaging recess provided in the main body side engaging portion 56 are engaged, and the main body side engaging portion 56 and the lid side engaging portion 64 are latched and held. The rightward sliding movement of the case lid member 60 with respect to the main body member 50 is restricted. Therefore, the state where the case lid member 60 is attached to the case body member 50, that is, the locked state is maintained. Thereby, the main body side engaging part 56 and the lid side engaging part 64 can be easily connected via the stopper member 71, and the case main body member 50 and the case cover member 60 are easily connected and held in the closed state. can do.

  If the case main body member 50 and the case lid member 60 are coupled and held in a closed state by such an unauthorized opening mechanism 70, the engagement with the stopper member 71 engaged with the main body side engaging portion 56 is released. In order to open the main substrate case 100 (main substrate assembly 30), it is necessary to cut the connecting portion 65 and separate the lid side engaging portion 64 from the case lid member 60. Therefore, after the main board case 100 is released, the cutting trace of the connecting portion 65 remains clearly, so that unauthorized opening can be detected at an early stage and illegal acts can be effectively suppressed.

  However, in the state where the case main body member 50 and the case lid member 60 are coupled and held in the closed state by the unauthorized release mechanism 70, as shown in FIG. 7, the bottom portion on the outer surface side of the case lid member 60 (for example, the dotted line A When the electronic device 32 is to be removed from the main control board 31 by cutting the portion with a cutter, a soldering iron, etc., the fraud prevention rib 80 (for example, The portion of dotted line B) must also be cut together, and extra time for cutting the fraud prevention rib 80 is required, so that such fraud can be prevented.

  Even if the outer surface side bottom portion of the case lid member 60 and the fraud prevention rib 80 are cut, the fraud prevention rib 80 and the main control board 31 are close to each other (for example, 0 to 2 mm). When the rib 80 is cut, there is a risk that the main control board 31 may be damaged by a cutter, a soldering iron, etc., and the main control board 31 does not operate even if the electronic device 32 is replaced with an unauthorized electronic device. Thus, such illegal acts can be effectively deterred without meaning.

  Further, in the unlikely event that the bottom portion where the anti-tampering rib 80 is not attached is cut or the connecting portion 65 is not cut, the case body member 50 and the case lid member 60 are pushed open, Even when the electronic device 32 is attempted to be illegally attached / detached by inserting the device, the concave portion formed so as to correspond to the shape of the electronic device 32 of the fraud prevention rib 80 (held in proximity to surround the electronic device 32) The act of attaching / detaching the electronic device 32 from the main control board 31 can be prevented, or even if the electronic device 32 is removed from the main control board 31, the action of taking out the electronic device 32 from that position can be restricted.

  The fraud prevention rib 80 is integrated with the case lid member 60 by a molding means such as injection molding using a transparent resin material such as ABS resin or polycarbonate (PC), like the case body member 50 and the case lid member 60. Therefore, the notation contents (company name, serial number, etc.) of the notation part 32a described on the surface of the electronic device 32 can be visually recognized, and the electronic device 32 should be removed by an unauthorized player. This fraud fact can be detected at an early stage when it is exchanged with the fraudulent electronic device.

  In addition, this invention is not limited to said embodiment, A various deformation | transformation is possible in the range of the summary that the fraud prevention rib 80 is formed close to the position facing the electronic device 32. For example, the attachment direction of the tamper-proof rib 80 may be formed so as to be close to the surface of the electronic device 32 in the left-right direction of the case lid member 60. Furthermore, in this embodiment, two tamper-proof ribs 80 are provided. However, it is preferable to provide one or more fraud prevention ribs 80. However, when a large number of fraud prevention ribs 80 are provided, the fraud prevention ribs 80 may be provided with the number and thickness of the fraud prevention ribs 80 to such an extent that the visibility of the written contents of the written portion 32a written on the surface of the electronic device 32 is not impaired. desirable. In the present embodiment, the fraud prevention rib 80 is used in the main control board 31 (electronic device 32). However, the fraud prevention rib 80 is similarly provided in other boards and other electronic devices, and such fraud prevention is performed. It is preferable to stop the act.
