A description will be given with reference to FIG. The middle cover body 30 can be internally fitted to the front cover body 10 made of a synthetic resin or the like, and has a box shape with an open back side.
Opening holes 31 corresponding to the opening portions 11 of the front cover body 10
Has opened. A slide groove 32 having the same height as the surface when the insertion plate 20 is mounted is formed on the surface of the middle cover body 30, and the insertion plate 20 slides on one side (to the left in the figure) of the slide groove 32. It is possible. A left center screw hole 33 corresponding to the left front screw hole 12d formed in the front cover body 10 is formed in the left portion of the opening hole 31.
A partition projection 34 is formed on the right side of the opening 31 so that the flat claw 24 and the protruding piece 25 can be attached thereto.
Three right front screw holes 12 (1) formed in the front cover body 10
2a, 12b, 12c), respectively, corresponding to the right middle screw hole 3
5 (35a, 35b, 35c) is open.

At the right edge of the opening hole 31, as will be described in detail later, a fixing screw (one-way screw described later in detail) 49 (49a to 49a-4) provided in advance for use after inspection.
9d) and four screw holding portions 39 (39a to 39d)
39d) is constituted by forming a gap 37c capable of holding a screw by using a screw holding plate 37a having elasticity and a rigid screw holding plate 37b. In addition, the screw holding plates 37a, 37b
Is attached to the back side of the bottom plate of the middle cover body 30, and the screw holding plate 37a is also attached to the back side of the projection 38a formed so as to protrude from the middle cover body 30. 39 are formed. A notch 38b is formed in the screw holding plate 37a so that it can be easily cut with a nipper or the like.
Each unit can be easily removed. A semicircular notch 36 is formed on the left side of the partitioning projection 34, and when a spare fixing screw 49 (49a to 49d) is provided in the holding section 39, a screw head can be placed on the holding section 39 so that the protrusion height can be increased. Make it lower. FIG.
(A) is a one-way screw 49 (49a-4) of a spare screw.
9D) is a plan view in which the holding portions 39 (39a to 39d) are mounted, and FIG.
Is provided in advance to facilitate the reuse of the control box after the inspection.

As shown in FIG. 7, the one-way screw 49, which is a kind of the fixing screw, has projections (51a, 51b) (52a, 51b) opposed to each other across the center point of the screw head 50.
2b) are formed and the projections 51a, 52a, 5
1b, 52b, projecting portions 5 adjacent in the clockwise direction
2a, 51b, 52b, and 51a are each formed in an inclined shape. Therefore, the tip of the screwdriver is connected to the protrusions 51a, 5a.
1b, and when turned clockwise, the protrusions 51a, 51b
However, when it is turned counterclockwise, it cannot hit the protrusion along the slope, so that it cannot be turned to the left. Therefore, if the screw is stopped with a one-way screw, the screw cannot be loosened because the reverse rotation cannot be performed.

At the lower corners of the left and right side surfaces, screw holes 38 are formed during fixing corresponding to the fixed front screw holes 16, which can be screwed to the back cover body 42 together with the front cover body 10. (See FIG. 2). In addition, fixed back screw holes 43 are formed on both side surfaces of the back cover body 42 to which the control board 41 is fixed, corresponding to the fixed screw holes 16.

Next, the assembling of the control box having the above structure will be described. First, when the insertion plate 20 is mounted in the slide groove 32 formed on the surface of the middle cover body 30, the flat claw 24 and the protruding piece 25 are separated from each other by the partition protrusion 34. The inside cover body 30
Is the same height. Then, the middle cover body 30 is provided inside the front cover body 10, and then, a box-shaped back cover body 42 for fixing a control board 41 provided with a control element is mounted on the back side of the middle cover body 30. Then, fixed front screw holes 16 formed in lower corners of the left and right side surfaces of the front cover body 10.
When the one-way screw 49 is attached to the
As shown in the cross section of FIG. 8B, the front cover body 10, the middle cover body 30 and the back cover body 42 are fixed through the fixing box 8 and the fixed back screw holes 43, and the control box 1 is shown in FIG. The posture shown in the figure. The insertion plate 20 mounted on the slide groove 32 formed in the middle cover body 30 cannot be removed by the front cover body 10. Also, if the one-way screw 49 is mounted and the screw is hardened with an adhesive, it becomes more difficult to remove it, which is effective.

As described above, when the one-way screw 49 is mounted in the fixed front screw hole 16, the control box 1 cannot be rotated through the one-way screw 49 itself because the one-way screw cannot be rotated in the reverse direction. Since the control element (control ROM) cannot be replaced unless the front cover body is destroyed, fraud prevention can be achieved. In addition, since the guide cylinder 13 is formed around the fixed front screw hole 16, the guide cylinder 13 is screwed with the one-way screw 49. Even if the screw head is cut with a saw or the like, the guide cylinder is damaged, so that it is possible to judge whether or not an illegal act has been performed, so that further illegal acts can be prevented.
When the control box 1 is used by attaching it to the back of a game machine, the internal control elements and the like can be seen through the opening 11, the transparent insertion plate 20, and the opening 31. Radiates heat through the heat release holes 21 formed in the insertion plate.

Next, the inspection of the control box 1 in use will be described. (First Inspection) The operation in the first inspection with the control box 1 removed from the back of the gaming machine or with the control box 1 attached to the gaming machine will be described. The window frame 15 at the left edge of the front cover body 10 will be described. Is cut and removed with a nipper or the like, the left edge opening (the opening formed by removing the three window frames 15) 18 becomes
It is formed as shown in FIG. At this time, since the corner 23a of the left stop body 23 is formed in a notch shape, the cutting edge of the nipper can be easily inserted into the windows 14a and 14b, and the three window frames 15 can be cut and removed easily. Then, the insertion plate 20 is pulled out and taken out from the left edge opening (the opening formed by removing the three windows 14 b) 18. By this operation, the control ROM provided on the control board 41 can be taken out through the opening 11 of the front cover body 10 and the opening hole 31 of the middle cover body 30. After the taking out and the inspection are completed, the control RO
M is mounted on the control board 41.

To use the control box 1 again, first, the notch 38b formed in the screw holding plate 37a is cut with a nipper or the like, and the one-way screw 49a in the holding portion 39a is removed. Then, the insertion plate 20 is pushed into the slide groove 32 from the left edge opening 18 until the right stop 29 is locked to the right edge of the opening 11. Then, the one-way screw 49a is inserted into the right screw hole 1 of the front cover body 10.
When attached to 2a, the front cover body 10, the insertion plate 20 (flat claw 24a) and the middle cover body 30 are fixed by the one-way screw 49a. This one way screw 49
In the case of a, the screw itself cannot be removed because the screw cannot be reversely rotated as described above, and the guide cylinder 13 does not hinder the screw head from being caught by the pliers. Since the cylinder 13 is damaged, it is possible to determine whether or not the wrongdoing has been performed. Therefore, the control box 1
The control ROM cannot be replaced unless the front cover or the like is damaged.

(Second Inspection) After removing the control box 1 from the gaming machine or while keeping the control box 1 attached to the gaming machine,
The cutting portion 26 formed on the right edge of the cutout 0 is cut with a nipper or the like to cut and remove the flat claw 24a. By this operation,
The insert plate 20 fixed by the one-way screw 49a is released, and the insert plate 20 is taken out from the left edge opening 18 formed by cutting at the time of the first inspection. The subsequent operation is substantially the same as that at the time of the first inspection, so that the control ROM is taken out, the inspection is performed, and after the inspection is completed, the control ROM is mounted. Then, the one-way screw 49b in the holding portion 39b is removed, the insertion plate 20 is slid and mounted, the one-way screw 49b is mounted in the right front screw hole 12b of the front cover body 10, and the front cover body 10 and the insertion plate 20 ( Flat claw 24b) and middle cover body 30
Is fixed. Since the control box 1 in this state is in the same state as that after the first inspection, the control ROM cannot be replaced unless the front cover body 10 is damaged.

(Third Inspection) This inspection is the same operation as the second inspection, in which the flat nail 24b is cut off, the insertion plate 20 is pulled out from the left edge opening, the control ROM is removed, and the inspection is performed. Install the ROM. Then, after removing the one-way screw 49c and inserting the insertion plate 20 through the left edge opening 18, the one-way screw 49c is attached to the right front screw hole 12c of the front cover body 10.

(Fourth Inspection) In this inspection, the control box 1 is removed from the gaming machine, the flat nails 24c are cut off, and the insertion plate 20 is pulled out from the left edge opening 18 as in the third inspection. Then, the control ROM is removed and inspection is performed, and the control ROM is mounted. After that, the last one-way screw 49
d is removed from the holding portion 39d, and the removed insertion plate 20 is inserted from the left edge opening 18 into the slide groove 32 until the right stop 29 is engaged with the right edge of the opening 11.
However, flat claws 24a, 2b formed at the right end of the insertion plate 20
4b and 24c cannot be used because they have been cut in each of the inspections.
Is attached to the left front screw hole 12d of the front cover, the front cover 10, the insertion plate 20, and the back cover 42 are integrally fixed. As described above, since the one-way screw 49d cannot rotate in the reverse direction and is surrounded by the guide tube 13, the one-way screw 49d cannot be removed even by pliers or the like. Then, the control box 1 in this state can be used by being attached to the back surface of the gaming machine.
OM cannot be replaced.

As described above, three flat claws 24 (24a, 24b, 24c) are formed at the right end of the insertion plate 20, and the left front screw hole 12d (the left screw hole 22, the left middle screw) is formed. By forming the holes 33), four inspections can be performed using the same control box 1.

It is needless to say that the number of inspections can be selected according to the number of flat claws 24 formed on the insertion plate 20. Further, the left front screw hole 12d (the left plate screw hole 22 in the insertion plate 20, and the left middle screw hole 33 in the middle cover body 30) is formed in the front cover body 10 without forming the flat claw 24 in the insertion plate 20. Allows one inspection. That is, by cutting and removing the windows 14a and 14b of the cutouts 18a to 18c with a nipper or the like, the insertion plate 20 can be removed and remounted, and then the one-way screw 49 is inserted into the left front screw hole 12d.
When the control box 1 is mounted, the control ROM of the control box 1 cannot be replaced unless the front cover is destroyed.

As the fixing screw, there is a well-known breaking screw (not shown) in addition to the one-way screw 49. After the breaking screw is tightened with a screw and a predetermined torque or more is applied, the screw head is cut off. This makes it impossible to pull out the breaking screw itself. The guide tube 13 is not always necessary when using the breaking screw. However, if the guide tube 13 is formed, the guide tube 13 is obstructed even if a slightly remaining screw portion is to be pulled out with a pliers. It is desirable because it cannot be pulled out. As described above, it is needless to say that whether to use a one-way screw, a break screw, or the like as the fixing screw is appropriately selected depending on an object to be used such as a control box. Alternatively, instead of the fixing screw (one-way screw or breaking screw, etc.), a method of using an ordinary screw (a screw that can be tightened or removed via a screw head) and fixing with an adhesive may be used. The act of illegally removing a screw with an adhesive becomes difficult, and if a one-way screw or a break screw is fixed with an adhesive, it becomes more difficult to remove. Needless to say, the object to which each of the screws is mounted and fixed is not limited to the control box of the present embodiment.

[0031]

According to the control box of the present invention, a guide cylinder is provided around a screw hole and is fixed via a fixing screw. Therefore, the fixing screw itself cannot be removed. Can not grab the screw with
Further, it is possible to prevent the control box from being opened by fraud. The control box according to the second aspect is screwed using a fixing screw, and the number of inspections can be reduced by forming a cutout on the front cover body and a flat claw on the slidable insertion plate. The same control box can be reused. In the control box according to the third aspect, the left front screw hole, the left plate screw hole, and the left middle screw hole are formed, so that the control box can be used even after all the flat claws are deleted. In the control box according to the fourth aspect, by providing the guide cylinder around the screw hole, when the screw is fixed with the fixing screw, the guide cylinder becomes a hindrance, so that further misconduct can be prevented. Further, in the control box of the gaming machine according to the fifth aspect, the screw is prevented from being removed by fixing the mounted screw with an adhesive.
