The head cover 72 has an inner diameter slightly larger than the outer diameter of the head 61 of the set screw 60 so that the set screw 60 can be screwed in. Is formed so as to have only a difference such that a tool such as pliers is not inserted, for example. Therefore, when the set screw 60 is screwed as far as shown in FIG. 11, the head 61 and the flange 65 of the set screw 60 are sandwiched by a tool such as pliers, and the set screw 60 is forcibly turned in the anti-screw direction. It cannot be rotated (counterclockwise) to loosen the set screw 60.

Therefore, once the set screw 60 is screwed into the mounting hole 51, the set screw 60 cannot be loosened. Need to be broken.
When the two breaking portions 71 are broken, the fixing portion 70 on the case side is fixed to the fixing portion 50 on the main body side by screwing, but the fixing portion 70 on the case side is fixed to the case cover 30. Since the rupture portions 71 are continuous only, the fixing portion 70 on the case side can be detached from the case cover 30 by the rupture of the two rupture portions 71, and the case cover 30 is separated from the case body 20 in this state. If it is pulled up in the direction, the fixing part 70 on the case side screwed to the fixing part 50 on the main body side
Is detached from the case cover 30 due to the breakage of the two break portions 71 and remains on the fixing portion 50 on the main body side, and the case cover 30 can be removed from the case main body 20.

To remove the case cover 30 from the case main body 20 and then fix the case cover 30 to the case main body 20 again, the other pair of left and right main bodies in which the two breaking portions 71 have not been broken yet. The fixing part 50 on the side and the fixing part 70 on the case side may be used. Also, the depth of the head cover 72 of the fixing part 70 on the case side is such that the head 61 of the set screw 60 is fixed to the head cover 72 even when the set screw 60 is temporarily screwed into the fixing hole 73 only. The head cover 72 has a depth that does not protrude from the upper end, and has a height substantially equal to the length of the set screw 60.

Therefore, even if the case cover 30 is not fixed to the case body 20 and the fixing screw 60 is screwed into the fixing hole 73 for temporary fixing, the fixing screw 60 hits another one. For example, the set screw 60 can be temporarily fixed even during transportation. Also, a pair of left and right body-side fixing portions 50 and a case-side fixing portion 70
The other pair of left and right main body side fixing portions 50 and the case side fixing portion which are not used are fixed.
By screwing the set screw 60 only into each fixing hole 73 in the set screw 70, the set screw 60 can be temporarily fixed.

For this reason, the case cover 30 is
When fixing to the product, the set screw 60 prepared separately is not lost or taken out of another packing, so that quick work is possible, and another packing is not required for transportation. . Also, above the left and right sides of the case cover 30, corresponding to the pair of claw portions 23 of the case body 20,
A pair of claw receiving portions 33 into which the pair of claw portions 23 respectively fit are formed. In the pair of claw receiving portions 33, in a state where the respective locking holes 32 of the case cover 30 are fitted in the respective locking portions 24 of the case main body 20, the case cover 30 is raised upward with the locking holes 32 as fulcrums. When raised, the opening of the case body 20 is closed as it is, a hole 34 is formed in which the pair of claws 23 fits from below.

Therefore, in a state where the pair of claw portions 23 are fitted in the pair of claw receiving portions 33, the locking portion 24 is fitted in the locking hole 32. Since it has an L-shape, the claw portion 23 stuck in the claw receiving portion 33
Unless you remove the case cover 30 from the case body 20
Can not be removed. (Mounting Procedure) Next, using the board case 10 having the above-described configuration, a procedure of fixing the case cover 30 to the case body 20 that is fixed to the back side of the game board 40 and houses the control board B,
A procedure for removing the case cover 30 from a state where the case cover 30 is fixed to the case main body 20 and a procedure for fixing the case cover 30 to the case main body 20 again will be described. First, as shown in FIGS. 1 and 6, the case main body 20 containing the control board B is fixed to the back side of the game board 40,

In this state,
The claw portion 23 fits into the claw receiving portion 33, and the case cover 30 is locked. Therefore, the case cover 30 is attached to the case body 20.
Even if the user releases his / her hand from the case body 20 during the work of fixing the case, the case cover 30 does not easily come off from the case body 20, and the fixing work can be performed efficiently.

When the claw portion 23 is fitted into the claw receiving portion 33, the claw portion 33 is slightly deformed outward as shown in FIG. In order to remove the claw portion 23 from the claw receiving portion 33, the case cover 30 must be deformed outward again. Therefore, even if the case is temporarily fixed, the case cover 30 is
Does not easily come off from

Next, in a state where the case cover 30 is temporarily fixed to the case body 20, as shown in FIG. 9, among the set screws 60 temporarily fixed to the fixing portion 70 on each case side, for example, the first set screw 60 is used. The set screw 60 temporarily fixed to the fixing portion 70 on the case side is screwed. That is, as shown in FIG. 10, the set screw 60 temporarily fixed to the fixing hole 73 of the case-side fixing portion 70 is further screwed by a screwdriver, and the set screw 60 is fixed to the main body side as shown in FIG. The fixing part 70 on the case side is fixed to the fixing part 50 on the main body side by inserting it into the mounting hole 51 of the part 50. Since the set screw 60 screwed into the mounting hole 51 of the fixing portion 50 on the main body side is formed so as to be screwable only in the screwing direction as described above, it is stopped using a screwing tool such as a screwdriver. Although the screw 60 can be tightened, the set screw 60 cannot be loosened. Also,
The set screw 60 screwed into the mounting hole 51 has the head 61 of the set screw 60 covered by the head cover 72 up to the upper end thereof. As a result, the set screw 60 cannot be loosened.

Therefore, the case cover 30 cannot be removed from the case body 20 by loosening the set screw 60. Next, from the case body 20 to the case cover 30
As shown in FIG. 12, the two breaking portions 71 of the fixing portion 70 on the case side are broken using a cutting tool such as a nipper, as shown in FIG. Each break portion 71 is formed to a width that is easily broken by a cutting tool such as a nipper, and two break portions are formed.
71 are arranged side by side at a predetermined facing distance so that the tip of a cutting tool such as a nipper can be easily inserted.

Further, since the fixing portion 70 on the case side is continuous only with the case cover 30 and the two breaking portions 71,
When the breaking portion 71 is cut, the fixing portion 70 on the case side and the case cover 30 can be detached. Therefore, when the case cover 30 is pulled in a direction in which the case cover 30 is detached from the case main body 20, as shown in FIG.
The case body with 70 screwed to the fixing part 50 on the body side
Can be removed from 20.

As described above, in order to remove the case cover 30 from the case main body 20, the two break portions 71 of the case-side fixing portion 70 screwed to the main body-side fixing portion 50 by the set screw 60 are broken. Therefore, the case cover 30 cannot be easily opened, and the case cover 30 cannot be opened without permission to remodel the control board B or replace a ROM storing a program or the like.
