Description

  The present invention relates to a board case that houses a control board for controlling a gaming machine such as a pachinko machine or a slot machine. More specifically, the present invention relates to a board case having an unauthorized opening prevention mechanism that prevents an illegal act on a control board by making the board case impossible to illegally open.

  A gaming machine such as a pachinko machine or a slot machine has a control board for controlling the operation of the gaming machine, and the control board is accommodated in a board case described in Patent Documents 1 and 2, for example. The substrate case has a base member and a cover member, and an unauthorized opening prevention mechanism is provided between the base member and the cover member. The unauthorized opening prevention mechanism is configured such that the substrate case cannot be opened and a trace remains when the substrate case is opened. Therefore, unauthorized opening of the substrate case can be discovered by the unauthorized opening prevention mechanism.

The unauthorized opening prevention mechanisms described in Patent Documents 1 and 2 include a base pedestal portion provided on the base member, a cover pedestal portion provided on the cover member, and a connecting member that connects them. The cover base portion overlaps the base base portion by covering the base member with the cover member. The connection member holds the cover member against the base member by being screwed over the cover pedestal portion and the base pedestal portion or by being fitted into both pedestal portions. Therefore, the substrate case can be held in a closed state. On the other hand, when opening the substrate case, it is necessary to cut the cover pedestal portion from the cover member, and the unauthorized opening of the substrate case can be found by the cutting trace.

The locking claw 3f is locked to the locking portion 2f by sliding the cover member 3 parallel to the base member 2 as shown in FIG. 6, and movement in the direction other than the removal direction is restricted by the locking portion 2f. Is done.

  The unauthorized opening prevention mechanism 5 prevents the substrate case 1 from being opened illegally and leaves a trace in the unauthorized opening of the substrate case 1, as shown in FIG. 6, the base pedestal portion 6, the cover pedestal portion 7, and the connecting member. 8 has a plurality of sets (for example, four sets). The base pedestal portion 6 has a box shape having an opening at one end as shown in FIG. As shown in FIG. 3, the base pedestal portion 6 is connected to a side surface (side surface on the rear end side in the sliding direction during assembly) 2 b of the base member 2 via connection portions 2 g to 21. The base pedestal portions 6 are connected via connection portions 2p to 2r.

  The cover pedestal portion 7 has a cylindrical shape having a through hole 7a as shown in FIG. On one side surface of the cover pedestal portion 7, a notch portion 7b and an opening portion 7c are formed. The notch 7 b is cut downward from the upper end of the cover pedestal 7, and the operating body 8 b of the connection member 8 is inserted therein. As shown in FIG. 7, the opening 7 c is formed at the lower end of the cover pedestal 7 and is configured to receive the base pedestal 6. As shown in FIG. 3, the cover pedestal portion 7 is connected to a side surface (side surface on the rear end side in the sliding direction during assembly) 3 b of the cover member 3 via connection portions 3 g to 3 l. Between the cover base parts 7, it connects via the connection parts 3p-3r.

The seal 9 covers the upper part of the through hole 7 a of the cover base 7 and covers the upper part of the neck 8 b 1 of the operation body 8 b of the connection member 8. Therefore, the neck portion 8b1 is prevented from coming off from the notch portion 7b by the seal 9, and the unauthorized operation of the connecting member 8 is surely prevented. The seal 9 is made of a material that tends to leave traces when peeled off.

  Hereinafter, a method for assembling the substrate case 1 will be described. First, the control board 14 is attached to the base member 2 as shown in FIG. Next, as shown in FIG. 6A, the cover member 3 is installed on the base member 2 at a position where the locking portions 2f of the base member 2 and the locking claws 3f of the cover member 3 are aligned. Subsequently, the cover member 3 is slid parallel to the base member 2, and the locking claw 3f is locked to the locking portion 2f. The base pedestal 6 and the cover pedestal 7 are overlapped in the direction orthogonal to the sliding direction by the slide.

  Next, as shown in FIG. 6 (B), one of the operating bodies 8b of the connecting member 8 is raised and the operating body 8b is pushed into the cover pedestal portion 7 (see FIG. 2). As a result, the slide body 8a of the connecting member 8 slides to a position straddling the cover pedestal portion 7 and the base pedestal portion 6 as shown in FIG. Stop. Accordingly, the cover member 3 is held at a position closed with respect to the base member 2 by the unauthorized opening prevention mechanism 5.

  By the way, the substrate case 1 is opened once or several times for inspection or the like. As shown in FIG. 8, the method of opening the substrate case 1 requires that the cover pedestal 7 is separated from the cover member 3 and the base pedestal 6 is separated from the base member 2. For example, by cutting the connection portions 3g, 3h, and 3p (see FIG. 3), the cover pedestal portion 7 is separated from the cover member 3, and by cutting the connection portions 2g, 2h, and 2p, the base pedestal portion 6 is changed to the base member. Separate from 2. As a result, the set of base pedestal 6 and cover pedestal 7 are separated from the base member 2 and the cover member 3. Then, the cover member 3 is slid in a direction away from the base member 2 to remove the cover member 3 from the base member 2.

  When the substrate case 1 is closed again after being opened for inspection or the like, the cover member 3 is slid and connected to the base member 2 as shown in FIG. Then, the seal 9 attached to the second cover pedestal portion 7 is peeled off from the back of the drawing, and the operating body 8b of the second connecting member 8 is raised from the back and pushed into the cover pedestal portion 7. As a result, the substrate case 1 can be closed. When the substrate case 1 is opened again, the second cover base 7 and the base base 6 are separated from the cover member 3 and the base member 2 from the back of the drawing, and the cover member 3 is removed from the base member 2. By the same method, the substrate case 1 can be closed a plurality of times (for example, a total of four times).

  The embodiment is formed as described above. That is, a slide coupling mechanism 4 is provided between the base member 2 and the cover member 3 to couple the cover member 3 and the base member 2 by sliding the cover member 3 relative to the base member 2 as shown in FIG. It has been. The unauthorized opening prevention mechanism 5 connects the cover pedestal portion 7 provided on the slide rear end side of the cover member 3, the base pedestal portion 6 provided on the base member 2, and the cover pedestal portion 7 and the base pedestal portion 6. The connecting member 8 is provided. The cover pedestal portion 7 and the base pedestal portion 6 overlap in a direction perpendicular to the sliding direction by sliding the cover member 3 with respect to the base member 2 and connecting them. The connecting member 8 is configured to be inserted at a position straddling the cover pedestal portion 7 and the base pedestal portion 6 and to be unable to move in the removal direction.

  Therefore, the substrate case 1 is closed by inserting the connection member 8. When the substrate case 1 is opened, it is not sufficient to cut the cover pedestal portion 7 from the cover member 3 as in the prior art. The base pedestal portion 6 is also cut from the base member 2, and the cover pedestal portion 7 and the base It is necessary to completely separate the pedestal portion 6 from the cover member 3 and the base member 2. This is because the cover pedestal portion 7 is located at the rear end of the slide, and even if only the cover pedestal portion 7 is separated from the cover member 3, the cover pedestal portion 7 remains in that position, thus preventing the cover member 3 from sliding in the opening direction. It is. Therefore, in order to completely separate the cover pedestal portion 7 and the base pedestal portion 6 from the cover member 3 and the base member 2, an unauthorized opening of the substrate case 1 can be easily found.
