As a result, the covering member 156 and the circuit board 61 are screwed to the main body frame 116 with the bottom plate 111 interposed therebetween (see FIG. 11B). In mounting and fixing the circuit board 61, when the stop hole 77 and the mounting hole 123 are aligned with each other in position, the circuit board 61 is slightly displaced so that the engagement projection 125 and the engagement hole 78 are engaged with each other. The one side in the width direction of the circuit board 61 which is not screwed is also fixed. Further, the connector mounting area 76 is shown in FIG. 7 and FIG.
As shown in (A), the covering member 156 is attached to the upper surface of the covering member 156 so that a portion other than the connector 75, in other words, a portion where the connection pattern 79 is formed.
Is covered by.

Next, the box body 1 whose top surface is open
The lid body 80 is put on 10. At this time, the box body 11
As shown in FIGS. 4 and 6, the engagement claw 138 on the 0 side is D
By being inserted in the direction, it is locked in the locking hole 99 on the lid 80 side, and the box body 110 and the lid 80 are positionally attached. Further, 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 in a state of being partitioned inside and outside the lid 80. As a result, wiring can be attached to and detached from the connector 75 without removing the lid 80. Also,
In this state, the tip portion of the partition wall 98 is covered with the covering member 15
By contacting the upper surface of the mounting portion of No. 6, the regulating portion 159 is arranged inside the lid body 80.

Then, in the direction B shown in FIGS. 4 and 6, the mounting hole 88 of the upper plate 81 and the mounting hole 96 of the lid frame 93 are fixed to the mounting hole 127 of the main body frame 116 with the screw 104, and the screw 104 fixing portion. A rectangular hologram seal 10

The one-way screw (screw) 140 is fastened to the mounting hole 131 of No. 6 (see FIG. 8A), and the screw 140 fastening portion is sealed with a rectangular hologram seal 106c. As a result, an assembly (circuit board box 62) in which the circuit board 61 is housed in a sealed state is formed in the internal space between the lid body 80 and the box body 110. In addition, such a circuit board 61
In the sealed state of, the connector mounting area 76 exposed to the outside has the connection pattern 79 with the covering member 156.
It is covered with. Therefore, even with the configuration in which the connector mounting area 76 is exposed to the outside, it is possible to prevent fraudulent acts using the connection pattern 79.

The lid 80 and the box body 1 described above are also included.
In the assembled state with 10, each equipment hole 135 to 13
The one-way screw 140 that is inserted through 7 is attached so as to cover the lid 80 from above, and is housed in the box 62 without coming off from the equipment holes 135 to 137. That is, in such a stored state, the mounting piece portions 83b and 83c of the lid body 80 and the mounting hole 8 are provided.
The upper wall surfaces near 6d individually prevent the one-way screws 140 from protruding. The method of mounting the one-way screw 140 is not limited to the one described in the embodiment. For example, with the box 62 assembled, the one-way screw 1
The head portion of 40 is completely pressed by a lid body 80 (a mounting piece portion or the like), or the one-way screw 140
And the diameters 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 equipped one-way screw 140 when 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 once tightened, it cannot be removed unless the screw is broken. Specifically, as shown in FIGS. 9 (A) and 9 (B), the screw groove provided in the head portion 141 has a contact surface portion 142, a concave portion 143, and a central hole portion 1.
And 44. And FIG. 9 (C) (D)
When tightening the screw 140 with the special slotted screwdriver 145 shown in FIG. 1, the central shaft portion 146 of the driver 145 is inserted into the central hole portion 144, and from this state, the driver 1
The screw 140 is tightened by contacting the contact piece 147 of 45 with the contact surface 142 and rotating the head 141 in one direction (clockwise direction in FIG. 9A). On the other hand, when the driver 145 rotates the head 141 in the other direction (counterclockwise direction in FIG. 9A) to remove the screw 140, the driver 145 slips into the recess 143. Screw 1 without being able to rotate head 141
40 cannot be removed. It should be noted that even with a normal flat head screwdriver, the head 141 is rotated in one direction to rotate the screw 140
It is possible to tighten it, but like the special flat-blade screwdriver 145, the central shaft 146 is fixed with the one-way screw 14

It is easier to carry out the tightening work by positioning with.

Further, the screws 104 and 140 for assembling the lid 80 and the box body 110 described above are configured to enter the outer wall surface of the lid frame 93 in a screwed state. Therefore, the hologram seals 106b and 106c for sealing the fixing portions of the screws 104 and 140 are attached on a flat surface having no protrusion, so that the seals 106b and 106c can be prevented from being peeled off and damaged, and the seals 106b and 106c can be prevented.
It becomes easy to discriminate fraudulent acts on 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 making the hologram pattern formed on the hologram layer a pattern that is difficult to forge, it is possible to prevent the sticker from being replaced due to fraudulent activity. In this hologram pattern, coherent light (laser light) incident on the surface of the hologram seal passes through the embossed surface of the hologram layer and enters the light reflection layer, and is reflected from the light reflection layer to the outside of the hologram seal as hologram interference light. It is formed by
In addition, when the hologram seal is peeled off, the hologram pattern does not return to its original shape even if it is reattached again, and thus the trace of peeling remains.

As described above, the circuit board box 62 is
Screws 104/140 between the lid 80 and the box body 110
The covering state of the circuit board 61 is secured by sealing the stop portion with the hologram seals 106b and 106c. Further, the conductive plate 100 provided in the box 62 can provide an electromagnetic shield effect.
Further, in the circuit board box 62, by forming the upper plate 81 and the conductive plate 100, which form the upper wall surface thereof, and the bottom plate 111, which forms the lower wall surface, from transparent materials, 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 the circuit board 61 is tampered with (for example, a jumper wiring is connected or an electronic component is mounted), the tampering can be immediately recognized.

Next, the mounting base 150 for mounting the above-mentioned circuit board box 62 on the mechanism plate 50 is shown in FIG.
Will be described with reference to. As shown in FIG. 3, the mounting base 150 is made of a rectangular plate made of synthetic resin (may be metal), and a pair of engaging rails 151 having an inverted L-shaped cross section are provided at predetermined intervals in the center of the substrate. It has been set aside. In addition, the installation direction of the engagement rail 151 is the mounting base 15

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 at the base of the release lever 153. It is set up. In addition, a fixing hole 155 for screwing the mounting base 150 to a mounting boss (not shown) on the mechanism plate 50 side is formed on the substrate surface of the mounting base 150.

The mounting base 150 is fixed to a predetermined portion on the mechanism plate 50 by being screwed to the mechanism plate 50 through the stop hole 155. Further, when mounting the circuit board box 62 on the mounting base 150,
The box 62 is slid from the left side with respect to the mounting base 150. At this time, the engagement rail 151 on the mounting base 150 side is in a state of engaging with the engagement piece 118 on the box 62 side, and the guide piece 152 guides the sliding movement of the box 62. The sliding movement of the box 62 causes the release lever 153 on the mounting base 150 side.
Elastically deforms downward, and finally, the locking hole 120 on the box 62 side engages with the engaging protrusion 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 with. That is, the circuit board box 62 is configured to be attachable to and detachable from the mounting base 150 fixed to the mechanism plate 50 with screws.

Next, a procedure for opening the above-mentioned circuit board box 62 for inspection of the circuit board 61 (inspecting whether the ROM is normal after shipment and delivery) and then restoring it to the closed state again is illustrated. It will be described based on 10. 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. Further, after the hologram seal 106c attached to the screw 140 fixing portion of the mounting piece portion 83a is peeled off, the connecting portions 84a and 85a are cut with a cutting tool such as a nipper with the marking "1" as a mark. As a result, the mounting piece 83a
Is completely separated from the lid 80 and the one-way screw 1
The box 40 is fixed to the box body 110. That is, the lid 80 is completely fixed to the box body 110, and the circuit board box 62 can be opened. Then, as shown in FIG. 10B, the lid 80 is removed from the box body 110 and the circuit board 61 is inspected. Further, by removing the lid 80 (cutting the connecting portions 84a and 85a), the equipment holes 135 to
The one-way screw 140 inserted into the 137 is ready to be taken out, and the one-way screw 140 inserted into the equipment hole 135 is taken out to restore the box 62. After that, when the circuit board box 62 is closed, as shown in FIG. 10C, with the lid body 80 covering the box body 110, the mounting holes 88, 96, 127 are fastened together with the screws 104, and the A new hologram seal 106b is attached to the screw 104 fixing portion. Further, the one-way screw 140 taken out is screwed into the mounting hole 86b of the mounting piece portion 83b using the marking "2" as a mark. As a result, the mounting hole 86b of the mounting piece portion 83b and the body frame 11 corresponding thereto are attached.
The 6 mounting holes 132 are fastened together with the one-way screw 140. Then, the screw 140 of this attachment piece portion 83b
By attaching a new hologram seal 106c to the stop portion, the circuit board box 62 is restored to the closed state again.

After that, when the circuit board box 62 is inspected again (second inspection), the hologram seal 10
6b is peeled off and the screw 104 is removed, and the marking "2"
The connecting portions 84b and 85b are cut with the mark. As a result, the mounting piece portion 83b is separated from the lid 80 to open the circuit board box 62. After that, similarly, a new hologram seal 106b is attached to the part fastened together 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 the connecting portions 84b and 85b is also attached. A new hologram seal 106 is screwed into the mounting hole 86c of the mounting piece portion 83c with the marking "3" as a mark.

By the way, the circuit board box 62 described above.
In the closed state, the connecting portions 84a to 84c / 85a
~ 85c is cut and the attachment piece parts 83a to 83c and the upper plate 81 are cut.
The circuit board box 62 cannot be opened unless the connection with the circuit board is released. Therefore, when the connecting portions 84a to 84c and 85a to 85c are cut by other than the inspection of the circuit board 61, it is possible to immediately and surely determine that the circuit board 61 has been tampered with by this cutting. The crime prevention 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 of No. 1 is cut off, the conductive plate 100 falls onto the circuit board 61. Therefore, even if an attempt is made to make a work on the circuit board 61 through the gap where the welding projection 82 is cut off, the conductive plate 1
00 blocks it. Also, the hologram seal 106
When a to 106c are removed, the hologram seal 10
Since the traces of 6a to 106c remain firmly, it can be immediately known that the fraud was performed.

As described above, the circuit board box 62 is

And a connecting portion 84 for separating the attachment piece portions 83a to 83c to release the fixed state between the box body 110 and the lid body 80.
By including 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 circuit board box 62 having a high crime prevention effect can be restored by screwing the one-way screw 140 into the mounting holes 86b to 86d.

Since the circuit board box 62 is provided with a plurality of the one-way screws 140, it is not necessary to prepare a one-way screw for each restoration work after the inspection, and the restoration work of the circuit board box 62 is facilitated. Further, since the outer wall surfaces of the attachment pieces 83a to 83d for fixing the box body 110 and the lid 80 to each other are made flat, and the hologram seal 106c is attached to the outer wall surfaces, the circuit board box 62 is formed. The closed state can be secured by the hologram seal 106c. Further, since the hologram sticker 106c is attached on a flat surface having no protrusion, peeling and damage of the sticker 106c can be prevented, and fraudulent acts on the sticker 106c can be easily discriminated.

In the circuit board 61 housed in the circuit board box 62 in a sealed state, the connection pattern 79 of the connector 75 is formed on the mounting surface of the connector 75, and in the sealed state of the circuit board 61. A connector mounting area 76 exposed to the outside is provided, and in the connector mounting area 76,
A covering member 156 that covers the connection pattern 79 is provided. Therefore, in a state where the circuit board 61 is sealed in the box 62, the work of attaching and detaching the external wiring connected to the circuit board 61 can be easily performed, and the connector mounting area 76 that is exposed outside is provided. Since the wire connection pattern 79 is covered by the covering member 156, it is possible to prevent an illegal act using the wire connection pattern 79. In addition, the configuration in which the wiring pattern is covered with a covering member that has a through hole for inserting a connector has a through hole for the connector even if the position or number of settings of the connector changes for each model. Since it is possible to deal with this by making 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 made of transparent synthetic resin, the state of the connecting pattern 79 can be confirmed while the connecting pattern 79 is covered with the covering member 156. Therefore, the connection pattern 79
Even if the fraudulent work is applied to the, the fraud can be immediately identified. The material of the covering member 156 is not limited to the transparent synthetic resin and may be an opaque synthetic resin or metal. Further, the method of attaching the covering member 156 is not limited to that described in the embodiment. For example, the covering member 156
A positioning hole for the circuit board 61 may be provided in the mounting.

The covering member 156 is not provided until the sealed state of the circuit board 61 is released.
Since the restriction portion 159 that enables the removal of the cover member 156 is provided, the covering member 156 is provided unless the sealed state of the circuit board 61 is released.
The wiring pattern 7 is more reliable.
It is possible to prevent cheating using 9. In addition, in the embodiment, the regulation portion 159 has a standing wall shape, but is not limited to this. For example, a screw stop portion or an engagement portion provided inside the lid 80 may be used as the restriction portion. Further, the covering member 156 is attached by a fixing means such as a one-way screw (which cannot be released unless it is broken) without providing a restriction portion, or the attaching portion of the covering member 156 is sealed by a sealing member such as a hologram sticker. By doing so, the attachment state of the covering member 156 may be secured. The cost can be reduced by using the sealing of the circuit board box 62.

Since the circuit board 61 is sealed by fixing the box body 110 and the lid body 80 with the one-way screw 140, the circuit board box 6
The sealed state of the circuit board 61 cannot be released unless the 2 is destroyed or a part of the box 62 (mounting piece portions 83a to 83c) is cut. Therefore, it is possible to make it more difficult to remove the covering member 156 illegally, and it is possible to more surely prevent an illegal act using the connection pattern 79.

The above-described 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-described embodiment, the mounting piece portions 83a to 83 are fixed by the one-way screw 140 that rotates only in the tightening direction.
Although it is configured to tighten c, instead of this, the mounting piece portions 83a to 8a are replaced by fastening members such as breakage mounting screws and rivets.
3c may be tightened, and the first and second fixing means for fixing the lid and the box body may be solvent or adhesive for welding. Also, the mounting hole 8

The circuit board box 62 is attached to the mechanism plate 50, but is not limited to this, and may be directly attached to the back surface of the game board 40.

The material of the mounting piece may be any material such as metal or synthetic resin, but is preferably synthetic resin which is easy to cut. Further, the detachable attachment piece does not necessarily have to be provided on the lid side, but may be provided on the box body side or may be provided on both sides of the lid body and the box body. Further, the number of the attachment pieces is not particularly limited, and it may be one that can be re-adhered only once and can be inspected only once. However, the more the mounting pieces are arranged in parallel, the more the number of times the circuit board box is inspected can be increased.
