  Conventionally, a control board equipped in a gaming machine is housed in a board case composed of an upper case and a lower case in order to prevent unauthorized modification such as replacement of the mounted ROM, and the board case is opened. Various measures have been taken to prohibit this. For example, in Patent Document 1, a plurality of connecting portions for connecting an upper case and a lower case are formed on the peripheral portion of the upper case of a substrate case, and at one connection, at least one connecting portion is used for one way. Disclosed inseparably by fasteners such as screws, rivets or pins. According to this method, in order to tamper with the control board, it is necessary to destroy the connecting portion or the vicinity thereof, and if the tampering is performed, the trace of destruction remains. The effect of preventing or preventing unauthorized modification is obtained. In addition, in the thing disclosed by patent document 1, the upper case is isolate | separated into an upper cover part and a side wall part in detail, and the several connection part is formed in the peripheral part of this upper cover part.

  On the other hand, a connector for receiving or sending a signal from another board (for example, a relay board or an electrical board) provided in the gaming machine is usually mounted on the control board. For this reason, an opening is provided in the upper case of the board case for storing the control board so as to face the connector, and the cable side connector is connected to the board side connector through the opening. . However, in this case, an unauthorized player or the like removes the cable-side connector and connects an unauthorized device to the board-side connector to input an unauthorized signal to the control board housed in the board case. There is a risk that an illegal act of illegally acquiring game media may be performed.

Therefore, in order to prevent such an illegal act, for example, as disclosed in Patent Document 2, after connecting the connector on the cable side to the connector on the control board side, a connector cover that covers both the connectors is provided. In this connector cover, a protrusion that engages with a connector on the control board side or a connector on the cable side is formed to cover both connectors and make it difficult to remove the connector cover attached to the board case. .

The fixed portion 89 is fixed by a one-way screw 90.

  As shown in an enlarged detail in FIG. 18, the fixing portion 89 has a cylindrical shape having a stepped hole 91 into which the one-way screw 90 can be inserted, and the fixing portion 89 and the flange portion 84 b of the substrate cover 84 are connected to each other. In between, weak portions 92 and 92 are formed as a pair of narrow connecting portions for connecting the two and making it easy to cut the fixing portion 89 from the substrate cover 84. Further, the fixing portion 89 is provided with a slit 93 at a portion sandwiched between the pair of weakened portions 92, 92, and the head of the one-way screw 90 is formed on the inner surface of the large-diameter hole portion of the stepped hole 91. A pair of saw blade-shaped non-slip portions 94 and 94 are formed to make it difficult to slip.

  Although the one-way screw 90 is not shown in detail in the drawing, like the wineway screw 76 described above, the one-way screw 90 is characterized by the shape of the engaging groove 90b that engages with the screw driver of the head 90a. Is provided so as to be operable only in the tightening direction. Once the fixing portion 89 and thus the substrate cover 84 are fixed by the one-way screw 90, the substrate cover 84 cannot be separated unless both the pair of weakened portions 92 and 92 are cut.

  Next, functions and effects of the above-described embodiment, particularly functions and effects of the main board case 23 provided in the housing 2 of the slot machine will be described.

  When assembling a gaming machine or the like, the main control board 45 is accommodated in the main board case 23, and the upper case 41 and the lower case 41 of the main board case 23, for example, the first coupling portion 47 from the top in FIG. Then, the connectors on the cable side are connected to the connectors 44a and 44d on the main control board 45 side through the openings 66 and 69 of the upper case 41, respectively, and the connectors are covered with each other. Connector covers 71 and 72 are attached. At that time, in one connector cover 71, for example, the first fixing portion 75 and the fifth fixing portion 75 from the upper left in FIG. 5 are fixed to the upper case 41 by the one-way screw 76 in an inseparable manner. Further, in the other connector cover 72, the head 53 of the fastener 49 is fitted into the coupling portion 47 of the upper case 41 through the fitting hole 79 at the center of the horizontal flange portion 78, for example. Thus, the upper case 41 and the lower case 42 are coupled to each other in an inseparable manner, and the connector cover 72 is fixed to the upper case 41 in an inseparable manner.

  In order to perform an illegal act such as illegally removing the connector covers 71 and 72 from this state and connecting an unauthorized device to the connectors 44a and 44d on the main control board 45 side, The fixed parts 75 and 79 that are fixed, the periphery thereof, or the fasteners 76 and 49 must be destroyed, and if an illegal act is performed, a trace of the destruction remains, so that prevention or prevention of the illegal act is prevented. Can be planned.

  On the other hand, when the connectors 44a and 44d need to be inserted and removed during maintenance or the like, the connector cover 71 is destroyed by destroying the fixed portions 75 and 79 fixed to the connector covers 71 and 72, the periphery thereof, or the fasteners 76 and 49. , 72 can be removed and the connectors 44a, 44d can be inserted and removed, so that maintenance work and the like are not hindered. Thereafter, when the connector covers 71 and 72 are attached again, the connector covers 71 and 72 are similarly attached to the upper case 41 by the fasteners 76 and 49 at the other fixing portions 75 and 79 of the connector covers 71 and 72. The connector covers 71 and 72 need not be replaced with new ones as long as they are fixed so that they cannot be separated. This contributes to a reduction in cost and an improvement in convenience.

  In particular, in the case of the present embodiment, each fixing portion 75 of one connector cover 71 is connected to the side surface of the connector cover 71 via a pair of fragile portions 77 and 77 which are a pair of narrow connection portions. Since the connector cover 71 can be separated from the connector cover 71 by cutting the connector 77, when the connector needs to be inserted and removed during maintenance or the like, the fixed portion 75 to which the connector cover 71 is fixed is connected to the corresponding pair of weak portions. By cutting 77, 77 with a nipper or the like, it can be easily separated from the connector cover 71, which can contribute to speeding up the work.

  In the other connector cover 72, when the head 53 of the fastener 49 is fitted into the coupling portion 47 of the upper case 41 through the fitting hole 79 as a fixing portion of the horizontal flange portion 78, The pin portion 52 passes through the through hole 63 at the bottom of the coupling portion 47 of the upper case 41, and the first engagement claw 51 at the tip of the pin portion 52 is prevented from being pulled out in the locking hole 65 of the fastening receiving portion 64 of the lower case 42. By engaging the state, the upper case 41 and the lower case 42 are coupled to each other by the fastener 49 so as not to be separated. At the same time, the peripheral edge portion of the fitting hole 79 of the horizontal flange portion 78 is sandwiched between the flange portion 56 of the fastener 49 and the coupling portion 47 of the upper case 41, so that the connector cover 72 is held by the same fastener 49. The upper case 41 is fixed inseparably. As described above, since the coupling of the upper case 41 and the lower case 42 and the fixing to the upper case 41 of the connector cover 72 are performed together by one fastener 49, the number of parts can be reduced correspondingly, and the cost can be reduced. It is possible to further contribute to cost reduction and convenience improvement. Moreover, when the connector 44d needs to be inserted and removed during maintenance or the like, the upper case 41 and the lower case 42 are joined by the fastener 49 by cutting the connecting portion 54 (particularly, the narrow fragile portion 54a) of the fastener 49 with a nipper or the like. Since both the state and the fixed state of the connector cover 72 are released, it is possible to further contribute to speeding up the work.

  Further, the door relay board connected to the connector 44a on the main control board 45 side accommodated in the main board case 23 via the cable 81 and attached to the back side of the front door 1 without being accommodated in the dedicated case. 33, the entire surface opposite to the mounting surface of the door relay board 33, including the connector 83a connected to the cable 81, is covered by the board cover 84, and the board cover 84 has 2 on the lower edge side. The connectors 83a to 83c on the side of the door relay board 33 and the connectors on the side of the cables 81, 85, and 86 are attached and detached unless the board cover 84 is removed. Since the cable 81 connected to the connector 83a on the door relay board 33 side is removed, the cable 81 is used. It can prevent or prevent illegal acts such as entering an incorrect signal to the control board 45. As a result, in combination with the above-described fraud prevention structure on the main board case 23 side, the fraud prevention effect can be reliably enhanced.

  In addition, at the time of maintenance of the door relay substrate 33, a pair of fragile portions 92, 92 that connect the fixing portion 89 and the flange portion 84b of the substrate cover 84 at each fixing portion 89 of the substrate cover 84 are provided with a nipper or the like. Since the substrate cover 84 can be removed by cutting the fixing portion 89 from the substrate cover 84 by cutting the substrate, the maintenance work is not hindered, and the implementation can be facilitated. In addition, when attaching a new board cover 84 after removing the board cover 84, it is necessary to remove the fixing portion 89 remaining on the inner frame panel 32 on the back side of the front door 1 together with the one-way screw 90. Since the slit 93 is provided and a pair of saw blade-shaped non-slip portions 94, 94 are formed on the inner surface of the large-diameter hole portion of the stepped hole 91 of the fixing portion 89, the fixing portion 89 is formed with radio pliers or the like. When the one-way screw 90 is sandwiched and rotated from the outer peripheral side, the anti-slip portions 94 can bite into the head portion 90a of the one-way screw 90, and the one-way screw 90 can be easily turned. This is advantageous.
