Part 113) are arranged coaxially with each other, so that the main control board case unit 60 and the connector cover 100 can be swung back and forth in an integrated connection state without removing the connector cover 100. . Thereby, the back surface side of the main control board 61 can be easily inspected by setting the main control board case unit 60 in a tilted state (see FIG. 10).

  The distance between the prize ball cassette 50 and the main control board case unit 60 is set so that the first hinge part 69 of the main control board case unit 60 is detached from the first hinge connecting part 112 of the bracket member 110. Is formed smaller than the relative movement amount for sliding the bracket member 110 in the right direction (in the hinge release direction). Therefore, even if the main control board case unit 60 is to be removed from the bracket member 110, the slide of the main control board case unit 60 is blocked by the left side surface of the prize ball cassette 50, so that the board case 62 is illegally removed and opened. It is possible to effectively prevent such illegal acts.

  Further, when the connector cover 100 is fitted to the main control board case unit 60, the second hinge portion 101 of the connector cover 100 can swing back and forth with respect to the second hinge connecting portion 113 of the bracket member 110, and left and right. Since the main control board case unit 60 and the connector cover 100 can be integrally swung back and forth because they are slidably engaged, sliding in the left-right direction is restricted. Further, when the main control board case unit 60 and the connector cover 100 are disengaged from each other and are swung back and forth independently, the main control board case unit 60 is moved in the right direction (hinge release direction). The first hinge portion 69 of the main control board case unit 60 comes into contact with the restriction rib 102 of the connector cover 100 and the slide is restricted. Thereby, removal of the main control board case unit 60 can be more strictly prevented. Thus, in the present embodiment, the main control board case unit 60 cannot be removed from the bracket member 110 unless the game board 20 or the prize ball cassette 50 is removed together with the connector cover 100.

  Next, the order of removing the main control board case unit 60 will be described. First, how to remove the main control board case unit 60 regularly will be described. In addition, this regular removal method means a regular order when the main control board case unit 60 is removed for the purpose of, for example, inspection of the main control board 62.

  First, by rotating the aforementioned turning lever (not shown) arranged in the front frame 2 in a predetermined direction, the connection between the game board 20 and the front frame 2 is released, and the game board 20 is moved forward. Remove from the front of the frame 2.

  Next, the connector cover 100 is pulled backward, and the second hinge portion 101 of the connector cover 100 is detached from the second hinge connecting portion 113 of the bracket member 110, thereby removing the connector cover 100 from the bracket member 110. Thereby, the slide restriction of the main control board case unit 60 by the connector cover 100 is released, and the main control board case unit 60 can be removed.

  Subsequently, the main control board case unit 60 is slid to the right in the tilted posture position where the main control board case unit 60 is swung rearward, whereby the first hinge portion 69 of the main control board case unit 60 is moved to the first hinge connecting portion of the bracket member 110. The main control board case unit 60 can be detached from the bracket member 110 by being detached from the bracket 112. The main control board case unit 60 is removed after the main control board case unit 60 is swung rearward when the main control board case unit 60 is slid to the right while the main control board case unit 60 is in the vertical position. This is because the slide is regulated by coming into contact with the surrounding wall 114 of 110.

  Next, how to remove the main control board case unit 60 in an unsteady manner will be described. The unsteady removal means an emergency order when the main control board case unit 60 is quickly removed due to, for example, a sudden failure or the like in the gaming machine. This is because removing the main control board case unit 60 together with the gaming board 20 requires a large work load, so that the main control board case unit 60 is lighter than the above-described routine method in an emergency such as a failure of a gaming machine. This is to allow early removal of the gaming machine so that it can be removed.

  First, the ball removal lever of the prize ball cassette 50 is operated, and the game balls stopped at the prize ball mechanism unit are discharged out of the machine through the ball removal passage or the like. At this time, an operation member (not shown) provided in the upper passage portion 33 is operated in the closing direction of the ball passage to close the ball passage of the upper passage portion 33 in the middle, so that the upstream in the prize ball mechanism portion Since the game ball on the side can be dammed up at this portion, only a part of the game balls that are stopped by the prize ball mechanism unit need be removed, and the ball removal operation for removing the prize ball cassette 50 is reduced. . On the contrary, when the amusement store is closed or at night, the operation member of the upper passage portion 33 is operated in the opening direction of the ball passage so that the ball passage of the upper passage portion 33 is opened. Since the prize ball cassette 50 cannot be removed unless all the game balls stopped at the prize ball mechanism unit are removed, the work of removing the main control board case unit 60 is further complicated and difficult, and security is improved. Can be increased.

  Subsequently, as shown in FIG. 8, the prize ball cassette 50 is removed from the cassette housing portion 34 of the back set board 30. Specifically, the upper and lower levers 36a and 36b are operated to be released, and the prize ball cassette 50 is pulled back from the cassette housing portion 34. Thereby, the slide restriction of the main control board case unit 60 by the prize ball cassette 50 is released. At this time, the game ball upstream from the prize ball cassette 50 has already been discharged by the above-described ball removal operation, so that even if the prize ball cassette 50 is removed, the game ball spills from the upstream side of the prize ball mechanism unit. There is no fear.

  Next, as shown in FIG. 9, the connector cover 100 is pulled rearward, and the second hinge portion 101 of the connector cover 100 is detached from the second hinge connecting portion 113 of the bracket member 110, so that the connector cover 100 is detached from the bracket member 110. Remove. Thereby, the slide restriction of the main control board case unit 60 by the connector cover 100 is released, and the main control board case unit 60 can be detached from the bracket member 110.

  Subsequently, as shown in FIG. 10, the main control board case unit 60 is set to the tilted posture position in which the main control board case unit 60 is swung rearward. As described above, by restricting the main control board case unit 60 to the tilted posture position, the slide restriction by the surrounding wall portion 114 is released. Then, as shown in FIG. 11, the main control board case unit 60 is slid rightward so that the first hinge part 69 of the main control board case unit 60 is detached from the first hinge connection part 112 of the bracket member 110. Thus, the main control board case unit 60 can be removed from the bracket member 110.

  As described above, according to the present embodiment, when the main control board case unit 60 and the prize ball cassette 50 are attached to the gaming machine, the main control board case unit 60 and the prize ball cassette 50 are located on the rear side of the gaming machine. Since the main control board case unit 60 is not substantially removed from the game board 20 unless the prize ball cassette 50 is removed from the back set board 30, the main control board case unit 60 is arranged adjacent to the left and right in the same state. It is possible to effectively prevent unauthorized removal of the substrate case unit 60 and to prevent unauthorized modification to the main control board 61. Here, in order to remove the prize ball cassette 50 from the back set board 30, it is necessary to remove the game balls upstream from the prize ball cassette 50 in advance, but this action during business is very conspicuous, The possibility that the prize ball cassette 50 is removed from the back set board 30 is small, and as a result, the possibility that the main control board case unit 60 is detached from the game board 20 is also reduced. be able to. On the other hand, when a sudden failure or the like occurs in the gaming machine, the main control board case unit 60 can be removed urgently only by removing the prize ball cassette 50 without removing the gaming board 20 from the front frame 2. Therefore, the workability of attaching / detaching the main control board case unit 60 is improved.

  In addition, this invention is not limited to the said embodiment, If it is a range which does not deviate from the summary of this invention, it can improve suitably.

  In the above-described embodiment, the slide opening / closing type substrate case has been described as an example. However, the present invention is not limited to this configuration. For example, a hinge opening / closing type substrate case may be used as long as the substrate case can contain the control board. Other types of substrate cases may be used.

  In the above-described embodiment, the main control board case unit 60 is detachably attached to the game board 20 (the bracket member 110) by the first hinge shaft. As long as the ball cassette 50 is arranged, the attachment / detachment mechanism of the main control board case unit 60 is not particularly limited.

  In the above-described embodiment, the case where the board case unit is applied to the main control board case unit has been described as an example. However, the present invention is not limited thereto, and the production control board case unit and the payout control board case unit are not limited thereto. The same effect can be obtained even when applied to other substrate case units.
