The operation of sealing the sealing case 1 using the special screw 36 after the base plate 2 and the cover 3 are fastened will be described here. The screw portion 38 of the special screw 36 is inserted into the through hole 34 of the one insertion portion 33 from below in the figure, and further screwed into the screw hole 31 of the screw receiving portion 30 from the tip. A special screw 36 is screwed by a driver or the like until the head 37 of the special screw 36 contacts the small-diameter portion of the through hole 34. If a rotational force is further applied to the driver or the like after the contact, the special screw 36 does not receive the torque of the driver or the like. Reverse rotation force is no longer accepted.

The base plate 2 and the lid 3 are formed of a pair of sealing members 2.
0 and the special screw 3
6 means that the sealing case 1 is sealed. The special screw 36 screwed into the inside is visible from the outside because the member is transparent, but is covered by the bottom surface of the screw receiving portion 30 and cannot be touched from the outside. In FIG. 5, a state in which the sealed sealing case 1 is fixed to a sheet metal base 56 of a game machine slot machine or the like will be described. Seal case 1
With the sheet metal base 5 so that the ceiling 10 is at the top (front).
6 and the normal bolt 46 is inserted into the through hole 2 of the push portion 21.

Next, a long special screw 47 is
Is inserted through the through hole 41 of one of the cylindrical portions 40 from the top in the figure, and the screw portion is screwed into the screw hole 49 of the sheet metal base 56. If the screw of the special screw 47 is screwed with a screwdriver or the like until the head of the special screw 47 touches the small-diameter portion of the through hole 41 as in the previous time, and the screw is further applied to the screwdriver, the special screw 47 will not receive the torque of the screwdriver or the like. Also, the reverse rotation force is no longer accepted. Thereby, the sealing case 1 and the sheet metal base 56 are additionally sealed with each other.

FIG. 6 is a cutaway view of a main part of the sealing case 1 in which the control circuit device is housed and sealed according to the present invention. The base plate 2 and the lid 3 are fastened by a pair of sealing members 20 and the sealing members 20, the sealing case 1 is sealed by special screws 36, and the sealing case 1 is fixed to a sheet metal base 56 by two bolts 46. At the same time, it is sealed with a special screw 47 so that it cannot be removed. For example, 2
Although the bolts 46 can be removed in the reverse rotation, the special screws 47 cannot be rotated in the reverse direction. Therefore, as long as the connecting portion 44 is not broken, the sealing case 1 is attached to the sheet metal base 56 by the special screws 47.
It is fixed by.

7 and 8, the operation of the above embodiment for inspecting the sealing case 1 by formal periodic inspection will be described. Sheet metal base 56 inside a slot machine or the like
Is mounted with a sealed case 1, and a control circuit device is housed in the sealed case 1. First, it is necessary to release the seal between the sealing case 1 and the sheet metal base 56. The inspector presses the pressing part 2 of one of the sealing members 20.
A pair of first and second cylindrical bodies 40 and 40;
(That is, a pair of cylindrical portions 40 into which the special screw 7 that cannot be rotated is screwed), and the flat tip of the driver D is inserted into the space 45 between these two plates.

When the driver is rotated, the two plates of the connecting portion 44 have a small thickness in one rotation direction (because the cross section is trapezoidal), so that the two plates are broken and the pair of cylindrical portions 40 and the cylindrical portion 40 are specially formed. It remains on the sheet metal base 56 together with the screw 47. Next, in FIG. 8, the two bolts 4 are
6 is removed by normal reverse rotation, and the sealing case 1 is separated from the sheet metal base together with the pair of sealing members 20 and the sealing members 20 in a state where the teeth are missing.

In this state, in the sealing case 1, the base plate 2 and the lid 3 are fastened by the pair of sealing members 20 and the sealing member 20. The sealing case 1 remains sealed by the special screw 36 in the insertion portion 33. Since the connection portion 44 between the screw receiving portion 30 and the insertion portion 33, which is the first cylindrical body, is not broken and is attached, the inspector determines that the sealing case 1 is not opened but in a normal state. At a glance, you can easily conclude instantly.

After the visual inspection, the sealing case 1 is mounted on the sheet metal base 56 again using the two bolts 46 in substantially the same manner as in FIG. 5. In this case, the second case has been damaged during the inspection. A spare special screw 47 is screwed through the pair of cylindrical portions 40 as the third cylindrical body.

The tube portions 40, 40 are arranged in a predetermined order for each inspection.
By checking the history of how many times the connecting portion 44 of the cylindrical body has been destroyed (missing of the cylindrical portions 40, 40), the number of times the visual inspection has been completed can be easily determined. It can be understood. After installing this embodiment, if the sealing case 1 is illegally removed from the sheet metal base 56 and the sealing case 1 is to be opened, as in FIGS. 7 and 8, a pair of cylindrical portions 40 as a second cylindrical body are formed. While breaking the connecting portion 44 of the cylindrical portion 40, the two bolts 46 are then removed to separate the sealing case 1 from the sheet metal base 56.

In the sealing case 1 taken out, the connecting portion 44 of the screw receiving portion 30 and the inserting portion 33 which is the first cylindrical body.
Also need to be destroyed. In this case, the screw receiving portion 30 and the insertion portion 33, which are the first cylindrical bodies, are missing from the pair of sealing members 20 and the sealing members 20 (also separated from the sheet metal base 56) together with the special screw 36 therein. Thereby, the sealing of the sealing case 1 is released. Then, a pair of sealing members 2
The connection between the base plate 2 and the lid 3 can be released by pulling the seal plate 20 and the sealing member 20 in opposite directions along the lid rail 15 and the base rail 19.

Then, these are turned around the connecting portion in the reverse Z direction in FIG. 1 to open the sealing case 1. Thereafter, the insertion portion 5 is pulled out from the locking hole 4, and the lid 3 is separated from the base plate 2, so that the control circuit device can be modified. If the connection portion 44 between the screw receiving portion 30 and the insertion portion 33, which is the first cylindrical body, was broken and dropped off, the seal was released at a glance,
Anyone can conclude instantly and easily.

It should be noted that the special screws 36 and 47 are well-known screws that cannot be loosened, screws that prevent reverse rotation in which the head has a groove on one side, or heads of the driver groove that have a predetermined torque or more. This includes screws that cannot be removed after fastening, which would break. Since the same sealing member 20 is used as a pair of sealing members 20 facing each other, the manufacturing cost can be kept low and the process can be simplified. The sealing member 20 may be made of a transparent synthetic resin, a metal may be embedded in the screw receiving portion 30, and a screw hole may be formed in the metal. Further, if the through hole 41 of the cylindrical portion 40 is formed as a screw hole, and a special screw 47 is screwed into the screw hole, a stronger double case seal can be realized.

In place of the stopper 27 on the lid rail 15 and the base rail 19, the pushing portion 2 of the sealing member 20 is used.
1 is provided with a stopper at the end of the sealing member 20 from the rail.
May not be detached. In addition, the lid rail 15 and the base rail 19 are not limited to a linear shape, but are formed in an arc shape, the sliding direction is set to the circumference, and the reverse rail of the sealing member 20 is also formed in an arc shape in accordance with the circumference. Is also good.

In the present invention, the sealing case 1 for accommodating the control circuit device is mounted on the gaming machine as long as the pair of sealing members 20 for attachment and the respective cylindrical portions 40 of the sealing members 20 and the connecting portions 44 of the cylindrical portions 40 are not destroyed. Cannot be removed from the case. Unless the pair of sealing members 20 for sealing and the screw receiving portions 30 of the sealing members 20 and the connecting portions 44 of the insertion portions 33 are destroyed, the sealing case 1 housing the control circuit device cannot be opened. Therefore, with regard to the sealing case 1 for accommodating the control circuit device, the connecting portions 44 of the mounting tube portions 40 and the tube portions 40 and the connecting portions 44 of the screw receiving portions 30 and the insertion portions 33 for case sealing are doubled. Since it can be sealed, it is almost completely prevented from remodeling.
