Even if the screw 13 is forcibly rotated by making a hole, the engagement pieces 16, 16 of the fixing member 7 remain engaged with the concave grooves 23 of each screw 13, so that the screw 13 is hard to come off and comes off. In this case, the engagement pieces 16, 16 are lost, and the trace is always left.

As described above, in order to separate the upper cover 6 from the lower cover 5, the control device 3 cuts the mounting pieces 10, 10 to thereby attach the screw holding portions 9 screwed to the mounting tabs 32, 32. , 9 must be separated from the upper cover 6, so that when the upper cover 6 is removed, a trace is always left. Therefore, the presence or absence of opening and closing of the upper cover 6 can be easily grasped. Nevertheless, since each of the mounting pieces 10, 10 has a structure that can be easily cut,
By cutting the mounting pieces 10 and 10 with a tool such as a nipper, the upper cover 6 can be easily removed, and the contents of the control elements installed on the substrate 8 can be easily checked.

In addition, the control device 3 has a stepped portion provided on the base end side of the helical portion 24 of the screws 13, 13 in the circumferential direction, and the engagement pieces 16, 16 provided on the lower cover 5 are provided. , Are engaged with the steps, so that the screws 13, 13
Even if the screw 13 is forcibly rotated by drilling a hole in the head 19 with an electric drill or the like, the screw 13 is hard to come off, and if it comes off, the engaging pieces 16, 16 will be lost and the trace will always remain. A situation in which the upper cover 6 is illegally removed without cutting the mounting pieces 10, 10 can be effectively prevented, and even if an unauthorized removal occurs, the situation can be quickly grasped. Therefore, according to the control device 3, it is possible to effectively prevent unauthorized replacement and unauthorized modification of the control elements such as the ROM 8 and the CPU.

Further, the control device 3 is configured such that the stepped portion is a concave groove 23 having a circumferential shape, and the engagement pieces 16, 1
6, the screw 13 is hardly disengaged even if the screw 13 is forcibly rotated, since the upper cover 6 does not cut the mounting pieces 10, 10. It is possible to more effectively prevent a situation in which an unauthorized removal is performed.

It should be noted that the control device of the present invention is not limited to the embodiment described above, and the configuration of the board, the upper cover, the lower cover, the fixing member, the shape and structure of the one-way type screw, etc. Changes can be made as appropriate without departing from the spirit of the invention.

For example, the number of screw holding portions provided on each upper fixed wing of the upper cover and the number of mounting tabs provided on each of the left and right lower fixed wings of the lower cover are not limited to four, but are two or three. However, the number may be five or more. Further, the number of mounting pieces for connecting each upper fixed wing and the screw holding portion is not limited to two, but may be one or three or more. Further, the position of the upper fixed wing or the lower fixed wing is 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. In addition, the fixing member is not limited to the one separate from the lower cover,
It may be provided integrally with the lower cover. When the fixing member is separated from the lower cover as in the above embodiment, there is an advantage that only the fixing member can be replaced when it is damaged. When the fixing member is provided separately from the lower cover, the fixing member may be screwed to or bonded to the lower cover. Further, the structure of the fitting region provided in the fixing member is not limited to the structure of the above embodiment.

The one-way type screw is not limited to a screw having a flat tip as in the above embodiment, but may have another shape such as a wood screw having a sharp tip. In addition, the head is not limited to the one provided with two screw protrusions, and may be a rotatable one with a plus-type driver provided with four screw protrusions. Further, the screw is not limited to a screw provided with a concave groove as a step as in the above embodiment, but may be a screw provided with a step of another shape. FIG. 7 shows an example of such a modification, in which the screw 29 is provided with a flange 22 as a step, and the base-side surface of the flange 22 is perpendicular to the axis.
The surface on the tip side is slightly inclined with respect to the axis. Even when the screw 34 having such a shape is used, the engagement pieces 16, 16 provided on the lower cover 5 engage with the vertical surface of the flange 22 at the time of screwing with the mounting tab 32, so that the screw is forcibly rotated. Is very unlikely to come off, so that the control device can more effectively prevent a situation in which the upper cover 6 is illegally removed without cutting the mounting pieces 10, 10. On the other hand, the screw holding portion can be changed to a structure that can hold a screw that is not screwed with the mounting tab. Although the control device used for the pachinko machine has been described in the above embodiment, the game machine using the control device of the present invention may be a game machine other than a pachinko machine such as a slot machine or a video game.
