Is slightly bent downward so that it can be easily engaged with the engagement rail 151 on the mounting base 150 at the time of mounting on the mounting base 150 described later in detail.

On the other hand, on one side wall in the width direction of the main body frame 116,
A mounting projection 126 having a mounting hole 127 corresponding to the mounting hole 88 on the lid body 80 is bent inward and formed.
A plurality of heat dissipation holes 128 are formed. On both side walls in the width direction of the main body frame 116, reinforcing pieces 1 are provided at both ends in the longitudinal direction.
29 is extended. The reinforcing piece 129 is bent inward from the extending portion, thereby pressing both side walls in the longitudinal direction of the main body frame 116 from the inside, thereby improving the strength of the main body frame 116. Also, because it closes the gap between the side walls,
It is impossible to illegally remodel by widening the side walls. In addition, such a reinforcing piece is not limited to the body frame 116,
It may be provided on the third side. Upper end portions of both side walls in the longitudinal direction of the main body frame 116 are formed as mounting pieces 130 bent inward, and the mounting pieces 130 are individually formed with mounting holes 86a to 86d on the lid body 80 side. Corresponding mounting holes 131-1
34 are drilled. In the vicinity of the mounting holes 132 to 134, mounting holes 135 to 137 for mounting the one-way screws 140 for mounting are inserted, respectively. An engagement claw 138 that engages with the locking hole 99 on the lid 80 is formed at one end of the mounting piece 130.

The lid 80 and the box main body 110 are attached to the circuit board 6 by the following assembly.
1 (circuit board box 62). First, the circuit board 61 and the bottom plate 111 are overlapped and mounted on the main body frame 116, and the engaging projection 125 of the engaging piece 124 is inserted into the engaging hole 78 of the circuit board 61. Next, the connector 75 of the circuit board 61 is inserted into the insertion hole 158 to mount the cover member 156 in the connector mounting area 76, and the mounting hole 157 of the cover member 156 and the stop hole 77 of the circuit board 61 are mounted to the mounting piece 122. The holes 123 are screwed together with screws 139. Thus, the cover member 156 and the circuit board 61 are fixed to the main body frame 116 with the screws 139 with the bottom plate 111 interposed therebetween (see FIG. 11B). In the fixing of the circuit board 61, when the hole positions of the stop hole 77 and the mounting hole 123 are aligned, the circuit board 61 is slightly displaced, so that the engagement protrusion 125 and the engagement hole 78 are engaged. The one side in the width direction of the circuit board 61 which is not screwed is also fixed. 7 and FIG.
As shown in (A), by attaching the covering member 156 to the upper surface, a portion other than the connector 75, in other words, a portion where the connection pattern 79 is formed, is covered by the covering member 156.
Covered by

Next, the box body 1 whose upper surface is open
10 is covered with a lid 80. At this time, the box body 11
As shown in FIG. 4 and FIG.
When the box body 110 and the cover 80 are positioned, the box body 110 and the cover 80 are positioned and attached. The partition wall 98 of the lid frame 93 is
The electronic component mounting area 74 and the connector mounting area 76 of the circuit board 61 are separated from each other inside and outside the lid 80. Thus, the wiring can be attached to and removed from the connector 75 without removing the lid 80. Also,
In this state, the tip of the partition wall 98 is
The restricting portion 159 is arranged inside the lid 80 by contacting the upper surface of the mounting portion 6.

4 and 6, the mounting hole 88 of the upper plate 81 and the mounting hole 96 of the lid frame 93 are screwed into the mounting hole 127 of the body frame 116, and the screw 104 fixing portion. To a rectangular hologram seal 10
Seal with 6b. Further, in the directions A and C shown in FIGS.
6 is fixed to the mounting hole 131 with a one-way screw (screw) 140 (see FIG. 8A), and the screw 140 fixing portion is sealed with a rectangular hologram seal 106c. Thus, an assembly (circuit board box 62) in which the circuit board 61 is housed in a sealed state in the internal space between the lid 80 and the box body 110 is formed. In addition, such a circuit board 61
In the sealed state, the connector mounting area 76 provided to be exposed to the outside has a connection pattern 79 in which the covering member 156 is provided.
It is covered with. Therefore, even in a configuration in which the connector mounting area 76 is provided so as to be exposed to the outside, it is possible to prevent an illegal act using the connection pattern 79.

The lid 80 and the box body 1
10 and the equipment holes 135 to 13
The one-way screw 140 inserted through 7 is accommodated in the box 62 without being detached from the equipment holes 135 to 137 by being attached so as to cover the cover 80 from above. That is, in such a storage state, the mounting pieces 83b and 83c of the lid 80 and the mounting holes 8
The upper wall surfaces near 6d individually prevent the one-way screw 140 from jumping out. The method of mounting the one-way screw 140 is not limited to the method described in the embodiment. For example, with the box 62 assembled, the one-way screw 1
40 is completely pressed down by the lid 80 (such as a mounting piece) or a one-way screw 140
And the diameter of the equipment holes 135 to 137 may be substantially the same. With such a configuration, it is possible to suppress the looseness of the provided one-way screw 140 while the circuit board box 62 is closed.

Here, the one-way screw 140 will be described. The one-way screw 140 is a special screw that turns only in the screw tightening direction, and cannot be removed once tightened unless the screw is destroyed. Specifically, as shown in FIGS. 9A and 9B, a screw groove provided on the head 141 has a contact surface portion 142, a concave portion 143, and a center hole portion 14.
And 4. When the screw 140 is to be tightened with the special flathead screwdriver 145 shown in FIGS. 9C and 9D, the center shaft 146 of the driver 145 is inserted into the center hole 144, and the screwdriver 145 is moved from this state.
The screw 140 is tightened by rotating the head 141 in one direction (clockwise direction in FIG. 9A) by bringing the contact piece 147 into contact with the contact surface 142. Meanwhile, driver 14
If the user tries to remove the screw 140 by rotating the head 141 in the other direction (counterclockwise direction in FIG. 9A) at 5, the driver 145 slips into the recess 143 and slips. Can not rotate the screw 14
0 cannot be removed. It is possible to rotate the head 141 in one direction and tighten the screw 140 with a normal flathead screwdriver.
45, one-way screw 140
The fastening work can be performed more easily by inserting the one-way screw 140 into the center hole 144 and positioning it with the one-way screw 140.

The screws 104 and 140 for assembling the lid 80 and the box body 110 are configured to enter the outer wall surface of the lid frame 93 in a screwed state. For this reason, the hologram seals 106b and 106c for sealing the screw 104 and 140 stop portions are stuck on a flat surface without projections, so that peeling and damage of the seals 106b and 106c can be prevented and the seals 106b and 106c can be prevented.
It becomes easy to determine the wrongdoing with c. Here, the hologram seal will be briefly described. The hologram seal includes a hologram layer, a light reflection layer, and an adhesive layer,
By forming the hologram pattern formed on the hologram layer into a pattern that is difficult to forge, it is possible to prevent the sticker from being replaced due to fraud. In this hologram pattern, coherent light (laser light) incident on the surface of the hologram seal enters the light reflection layer through the embossed surface of the hologram layer, and is reflected from the light reflection layer to the outside of the hologram seal as hologram interference light. It is formed by doing.
Also, when the hologram seal is peeled off, the hologram design does not return to the original shape even if it is re-attached, so that traces of peeling remain.

As described above, the circuit board box 62
Screws 104 and 140 between lid 80 and box body 110
The covering portion of the circuit board 61 is secured by sealing the stopped portion with the hologram seals 106b and 106c. In addition, the conductive plate 100 provided in the box 62 can provide an electromagnetic shielding effect.
Further, the circuit board box 62 is formed by forming the upper plate 81 and the conductive plate 100 constituting the upper wall surface thereof and the bottom plate 111 constituting the lower wall surface thereof from a material having transparency, so that the mounting surface of the circuit board 61 ( The upper surface) and the solder surface (lower surface) can be seen through from the outside. For this reason,
When an illegal operation (for example, an illegal operation of connecting a jumper wiring or mounting an electronic component) is performed on the circuit board 61, the illegal operation can be immediately recognized.

Next, a mounting table 150 for mounting the circuit board box 62 to the mechanism plate 50 will be described with reference to FIG.
This will be described with reference to FIG. As shown in FIG. 3, the mounting base 150 is formed of a rectangular plate formed of a synthetic resin (or metal), and a pair of engaging rails 151 having an inverted L-shaped cross section is provided at a predetermined interval in the center of the substrate. It is laid out. The direction in which the engaging rails 151 are provided depends on the mounting base 15.

A guide piece 152 orthogonal to the substrate surface protrudes from each of the long sides (front and rear edges) of the zero. A release lever 153 that elastically deforms is formed at the right end of the mounting base 150, and an engagement protrusion 154 that engages with the locking hole 120 on the box body 110 side projects from the base of the release lever 153. Has been established. Further, a stop hole 155 for screwing the mounting base 150 to a mounting boss (not shown) on the mechanism plate 50 side is formed in the substrate surface of the mounting base 150.

The mounting table 150 is fixed to a predetermined portion on the mechanism plate 50 by being screwed to the mechanism plate 50 through the stopper hole 155. When mounting the circuit board box 62 to the mounting base 150,
The box 62 is slidably mounted on the mounting table 150 from the left side. At this time, the engagement rail 151 on the mounting base 150 is engaged with the engagement piece 118 on the box 62, and the guide piece 152 guides the sliding movement of the box 62. Then, the release lever 153 on the mounting base 150 side is formed by the sliding movement of the box 62.
Is elastically deformed downward, and finally, the locking hole 120 on the box 62 side engages with the engaging projection 154 on the mounting base 150 side, and the mounting of the box 62 is completed. On the other hand, when removing the circuit board box 62 from the mounting base 150, the release lever 153 is pushed downward to release the engagement between the locking hole 120 and the engagement protrusion 154, and the box 62 is slid leftward from this state. Can be easily removed. That is, the circuit board box 62 is configured to be detachable from the mounting base 150 fixed to the mechanism plate 50 with screws.

Next, the procedure for opening the above-mentioned circuit board box 62 for inspection of the circuit board 61 (to check whether the ROM is genuine after shipment and delivery) and thereafter restoring the closed state again is shown in FIG. 10 will be described. First, in the closed state of the circuit board box 62 shown in FIG. 10A, the hologram seal 106b is peeled off and the screw 104 is removed. Also, after peeling off the hologram seal 106c stuck to the screw 140 fixing portion of the mounting piece portion 83a, the connecting portions 84a and 85a are cut with a cutting tool such as a nipper using the mark "1" as a mark. Thereby, the mounting piece 83a
Is completely separated from the lid 80 and the one-way screw 1
Due to 40, it is fixed to the box body 110. That is, all the fixing of the lid 80 to the box body 110 is released, and the circuit board box 62 can be opened. Then, as shown in FIG. 10B, the lid 80 is removed from the box main body 110, and the circuit board 61 is inspected. In addition, by removing the lid 80 (cutting the connecting portions 84a and 85a), each of the equipment holes 135 to 135 is removed.
The one-way screw 140 inserted into the hole 137 can be taken out, and the one-way screw 140 inserted into the equipment hole 135 is taken out for restoring the box 62. Thereafter, when closing the circuit board box 62, as shown in FIG. 10C, the mounting holes 88, 96, and 127 are jointly fastened with the screw 104 while the lid body 80 is placed on the box body 110, and the A new hologram seal 106b is attached to the screw 104 stop portion. The one-way screw 140 that has been taken out is screwed into the mounting hole 86b of the mounting piece 83b with the mark “2” as a mark. Thereby, the mounting hole 86b of the mounting piece 83b and the corresponding main body frame 11 are formed.
The six mounting holes 132 are fastened together by one-way screws 140. And the screw 140 of this mounting piece 83b
By attaching a new hologram seal 106c to the stop portion, the circuit board box 62 is restored to the closed state again.

Thereafter, when inspecting the circuit board box 62 again (second inspection), the hologram seal 10
6b is peeled off and the screw 104 is removed, and the stamp “2”
The connecting portions 84b and 85b are cut with the mark as a mark. As a result, the mounting piece 83b is separated from the lid 80, and the circuit board box 62 is opened. Thereafter, similarly, a new hologram seal 106b is adhered to the portion fastened with the screw 104, and the one-way screw 140 (one-way screw 140 of the equipment hole 136) taken out along with the cutting of each of the connecting portions 84b and 85b. A new hologram seal 106 is screwed into the mounting hole 86c of the mounting piece 83c with the mark “3” as a mark.

To 85c and the mounting pieces 83a to 83c and the upper plate 81.
The circuit board box 62 cannot be opened unless the connection to the circuit board is released. Therefore, in a case where the connecting portions 84a to 84c and 85a to 85c are cut other than the inspection of the circuit board 61, it is possible to immediately and reliably determine that the circuit board 61 has been tampered with by the cutting. The security effect of the circuit board box 62 can be enhanced. In the configuration of the circuit board box 62, the upper plate 8
Even if the welding projection 82 is cut off, the conductive plate 100 falls on the circuit board 61.
00 blocks it. Also, the hologram seal 106

And a connecting portion 84 for separating the mounting pieces 83a to 83c to release the fixed state between the box body 110 and the lid 80.
With the provision of a to 84c and 85a to 85c, the box 62 can be opened and closed a plurality of times with the circuit board box 62 attached to the ball game machine 1. Therefore, even when the circuit board 61 is inspected after shipment and delivery, the circuit board 61 can be easily inspected without breaking the box 62. When the box 62 is closed after the inspection, the one-way screw 140 is screwed into the mounting holes 86b to 86d, whereby the circuit board box 62 having a high security effect can be restored again.

Further, since a plurality of the one-way screws 140 are provided in the circuit board box 62, it is not necessary to prepare one-way screws for each restoration work after the inspection, and the restoration work of the circuit board box 62 can be easily performed. Also, the outer wall surfaces of the mounting pieces 83a to 83d for fixing the box main body 110 and the lid body 80 are made flat, and the hologram seal 106c is attached to the outer wall surfaces. Can be secured by the hologram seal 106c. Further, since the hologram seal 106c is stuck on a flat surface without protrusions, peeling and damage of the seal 106c can be prevented, and misconduct with respect to the seal 106c is easily determined.

The circuit board 61 housed in the circuit board box 62 in a sealed state has the connection pattern 79 of the connector 75 formed on the mounting surface of the connector 75 and the circuit board 61 in the sealed state. A connector mounting area 76 exposed to the outside is provided.

For this reason, in the state where the circuit board 61 is sealed in the box 62, the work of attaching and removing the external wiring connected to the circuit board 61 can be easily performed, and of course, the connector mounting area 76 provided to be exposed to the outside is provided. Since the connection pattern 79 is covered by the covering member 156, fraudulent acts using the connection pattern 79 can be prevented. In addition, the configuration in which the connection pattern is covered with a covering member in which an insertion hole for inserting a connector is drilled allows the insertion hole for the connector to be drilled even if the position of the connector or the set number changes for each model. Since it is possible to cope with the above by forming a covering member, it is possible to cover various types of connection patterns at low cost. Further, in this configuration, since the insertion hole can be formed at various positions of the covering member, the degree of freedom in designing the connector in the connector mounting area can be improved. For example, even when the connectors are provided in two stages in the connector mounting area, the connection pattern can be easily covered.

Further, since the covering member 156 is formed of a transparent synthetic resin, the state of the connection pattern 79 can be confirmed while the connection pattern 79 is covered with the covering member 156. For this reason, the connection pattern 79

Can not be removed, and the connection pattern 7 can be more reliably
9 can be prevented. In the embodiment, the restricting portion 159 has an upright wall shape, but is not limited to this. For example, a screwing portion or an engaging portion provided inside the lid 80 may be used as the restricting portion. In addition, the covering member 156 is attached by a fixing means such as a one-way screw (which cannot be released unless it is destroyed) without providing a regulating portion, or the mounting portion of the covering member 156 is sealed with a sealing member such as a hologram seal. Thus, the mounting state of the covering member 156 may be secured. The use of the sealing of the circuit board box 62 is lower in cost.

Also, the circuit board 61 is sealed by fixing the box body 110 and the lid 80 with one-way screws 140, so that the circuit board box 6
The sealing state of the circuit board 61 cannot be released unless the box 2 is destroyed or a part of the box 62 (the mounting pieces 83a to 83c) is cut. For this reason, unauthorized removal of the covering member 156 can be made more difficult, and further, unauthorized use of the connection pattern 79 can be more reliably prevented.

The above embodiment does not limit the present invention, and various modifications can be made within the scope of the present invention. For example, in the above embodiment, the one-way screws 140 that turn only in the tightening direction are used to attach the mounting pieces 83a to 83.
