Are screwed at the respective corners of the substrate 8, and the substrate 8 is covered by the upper cover 9 without forming a large gap between the substrate 8 and the surface of the substrate 8. Even if the screwing of the portion of the screwing portion between the upper cover 9 and the chassis 4 and the lower cover that is exposed to the outside of the upper cover 9 is illegally released, there is a gap between the upper cover 9 and the surface of the substrate 8. Is not formed. Therefore, it is possible to prevent a situation in which the control element is illegally replaced or remodeled from the gap between the upper cover 9 and the surface of the substrate 8. Further, such a fraud prevention effect becomes more reliable as the gap between the upper cover 9 and the surface of the substrate 8 becomes smaller.

Next, a modified example of the screw holding section 14 will be described.
First, a mode in which the opening operation of the upper cover 9 can be easily performed without using a tool such as a nipper will be described. That is,
As shown in FIGS. 9 to 11, the screw holding portion 14 and the upper fixed wing 1
3 are formed in a thin plate shape, respectively, and cuts 34, 34 are formed in each of the mounting pieces 33, 33 in parallel with the upper surface of the upper fixed blade 13. hand,
These portions are thin portions 33a, 33a. According to this, when the sealed upper cover 9 is opened, the mounting piece 33 of the screw holding portion 14 that has been screwed is used.
11B, the attachment piece 33 is easily broken at the thin portion 33a by pushing the finger down to the side opposite to the cut 34 as shown in FIG. 11B, and the connection between the screw holding portion 14 and the upper fixed wing 13 is performed. Can be easily released. Therefore, a tool is not required, and the operation of releasing the seal is improved.

On the other hand, in the above embodiment, when the wood screw 19 is fastened to the screw holding portion 14, a rotational force acts on the screw holding portion 14 in the screw tightening direction.
There is a possibility that the screw holding portion 14 is separated from the upper fixed wing 13 due to breakage. Therefore, in order to effectively prevent the occurrence of such a problem, as shown in FIG. 10, the lower end of the cylindrical screw holding portion 14 is slightly longer than the above-described embodiment toward the lower cover 10, and Ribs 27 radially formed on the mounting tabs 27 of the lower cover 10.
a, 27a,... may be formed into grooves 32, 32,. According to this, when the upper and lower covers 9, 10 are assembled, the ribs 27a, 27a,... In the mounting tabs 27, 27,.
4 are engaged with the grooves 32, 32,..., And the rotation of the screw holding portions 14, 14,.
Even when the screws are tightened, the respective screw holding portions 14 do not rotate and are not cut from the upper cover 9.

The ribs 27a and the grooves 32 serving as engaging portions for restricting the movement of the screw holding portion 14 may be provided at least in one corresponding position, and their specific shapes can be appropriately changed. In addition, the attachment pieces 33, 33 in the modified example are formed in a thin plate shape, but any other shape such as a bar shape or a disk shape may be used as long as the shape can be pushed down with a finger and cut. Furthermore, when the upper fixed wing 13 is not formed, the screw holding portion 1 simply connected to the side of the upper cover 9 with a thin portion is also provided.
4 may be protruded, and the periphery thereof may be surrounded by a wall-shaped protective cover.

On the other hand, the control device of the present invention is not limited to the above-described embodiment at all. Changes can be made as appropriate without departing from the spirit of the present invention. For example, the number of screw holding portions provided on each of the left and right upper fixed wings of the upper cover and the number of mounting tabs provided on each of the right and left lower fixed wings of the lower cover are not limited to four, but may be two or less. The number may be three, or may be five or more. The positions of the upper fixed wing and the lower fixed wing are not limited to the left and right edges of the upper and lower covers, but may be the upper and lower edges of the upper and lower covers.

Further, the one-way type screw is not limited to a wood screw having a sharp tip as in the above embodiment, and may be a screw having another shape such as a screw having a flat tip. When a screw having a flat tip is used, it is preferable that a screw groove is previously formed in the mounting tab of the lower cover. Although the pachinko machine has been described in the above embodiment, the gaming machine of the present invention may be a gaming machine other than a pachinko machine such as a slot machine or a video game.

[0023]

According to the first aspect of the present invention, a plurality of screw holding portions holding one-way type screws are arranged on the edge of the upper cover in a radial direction from the center of the screw holding portion. Since the plurality of attachment pieces are integrally connected and at least one screw holding portion is screwed to the lower cover by the screw, the upper cover is screwed to the lower cover to separate the upper cover from the lower cover. In this structure, the mounting piece must be cut while leaving the screw holding portion, and if the upper cover is removed improperly, the trace is always left.
Therefore, it is possible to easily detect a fraudulent situation, and prevent a situation in which a fraudulent player operates conveniently. Nevertheless, since each screw holding part is easy to cut from the main body of the upper cover by the mounting piece,
The upper cover can be easily removed, and the control elements on the board can be easily checked.
