At both ends on one side in the width direction in the lower surface area, mounting pieces 122 each having a mounting hole 123 formed therein are formed. At both ends on the other side in the width direction in the lower surface area, engaging pieces 124 provided with engaging projections 125 are provided. Is formed. The tip of the engaging piece 118 is bent slightly downward so as to be easily engaged with the engaging rail 151 on the side of the mounting base 150 when mounted on the mounting base 150 described later in detail.

Further, on one side wall in the width direction of the main body frame 116,
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 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. Further, locking grooves 138 for locking the engaging claws 96 on the lid 80 side are formed at two front and rear positions on the distal end side 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 161 in the connector mounting area 76, and the mounting hole 162 of the cover member 161 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 161 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. 12A). 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 12, the covering member 161 is attached to the upper surface of the connector mounting area 76, so that the portion other than the connector 75, in other words, the portion where the connection pattern 79 is formed, is covered by the covering member 161. Coated. The covering member 161 covering the connection pattern 79 in this manner is positioned with respect to the bottom plate 111 by fitting the mounting protrusion 166 into the mounting hole 111a of the bottom plate 111.

Next, the box body 1 whose upper surface is open
10 is covered with a lid 80. At this time, as shown in FIGS. 4 and 6, the four engaging claws 96 on the lid body 80 are locked in the locking grooves 138 on the box body 110 side by being inserted in the C to F directions, respectively. Main body 110 and lid 8
Zero positioning is performed. The engagement between the engagement claw 96 and the engagement groove 138 is performed as shown in FIG.
First, as shown in FIG.
And then, as shown in FIGS. 11B and 11D,
The cover 80 (engaging claw 96) is slid to move the locking groove 1
38. Since this engagement state is not released unless the fixed state is released, it takes the place of the fixed part. For this reason, the number of fixed portions can be reduced, and assembling is easy and cost reduction can be caused. That is, if there are such engaging portions at the four corners, it is not necessary to fix all the four corners (the four corners cannot be opened). In addition, the partition wall 98 of the lid frame 93 is in a state where the electronic component mounting area 74 and the connector mounting area 76 of the circuit board 61 are partitioned inside and outside the lid 80. Thereby, without removing the lid 80,
Wiring can be attached to and removed from the connector 75.

In the directions A and B shown in FIGS. 4 and 6, the mounting hole 86a of the mounting piece 83a is inserted into the body frame 116.
(See FIG. 8A). 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 such a sealed state of the circuit board 61, the connector mounting area 76 provided to be exposed to the outside is provided.
The connection pattern 79 is covered with a covering member 156. 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. Further, in such an assembled state, the leading end portion of the partition wall 98 comes into contact with the covering member 161 so that the respective regulating walls 164 and 165 can be covered with the cover 80.
It is arranged inside. By this, it is screw 13
Even if 9 is removed, the covering member 16 is not removed unless the sealed state of the circuit board 61 (the fixed state of the lid 80) is released.
1 cannot be removed. Further, since the conductive plate 100 is provided in the circuit board box 62, an electromagnetic shielding effect can be obtained. 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. Therefore, when an unauthorized 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.

Further, the above-mentioned lid 80 and 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. In such a configuration, when the circuit board box 62 is closed, the mounted one-way screw 14
Zero play can be suppressed.

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.

Further, the circuit board box 6 of the present embodiment
2, the lid 80 and the box body 1 as shown in FIG.
The ten screw (one-way screw 140) fixing portions are covered with a transparent ultraviolet curable resin 170 having adhesive strength. As a specific process, the lid 8
When the box body 110 and the box main body 110 are assembled as the circuit board box 62, as shown in FIG. 13A, the liquid ultraviolet curable resin 170 is discharged from the liquid discharging device 171 to the screw 140 stop portion. Thereby, the mounting hole 8
6a to 86d are formed in concave portions formed in upper portions thereof.
As shown in FIG. 3 (B), a predetermined amount of the ultraviolet curable resin 17 is used.
0 is injected. The injection amount of the ultraviolet curable resin 170 is
The amount is set such that the head 141 of the screw 140 completely enters the resin 170. Then, as shown in FIG. 13C, ultraviolet rays are irradiated from the ultraviolet irradiation device 172 to the ultraviolet curable resin 170 in the concave portion,
The ultraviolet curable resin 170 cures at a speed of seconds,
The screw 14 is formed by the cured ultraviolet curable resin 170.
The circuit board box 62 in which the zero-stop portion (the head 141 of the screw 140) is completely covered is completed.

Next, a mounting table 150 for mounting the above-described 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.
0 is the left-right direction along the long side. 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 via the retaining 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 projection 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.

By the way, when the circuit board box 62 is mounted on the ball game machine 1 via the mounting base 150, the cover member 161 is mounted so that the side on which the covering member 161 is disposed is on the upper side, as shown in FIG. In other words, the circuit board box 62 shown in FIG. 11 is mounted such that the left side thereof faces upward. Therefore, even when the fixed state between the lid 80 and the box main body 110 is released by an inspection of the circuit board 61 described later or the like, the engagement between the engaging claw 96 on the lid 80 and the locking groove 138 on the box main body 110 is prevented. Since the engaged state (the state where the engaging claw 96 is hooked on the locking groove 138 and the lid 80 hangs on the box body 110) is maintained,
The opening and closing work of the circuit board box 62 is facilitated.

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 then restoring the closed state again will be described. 10 will be described. First, in the closed state of the circuit board box 62 shown in FIG. 10A, the connecting portions 84a and 85a are cut with a cutting tool such as a nipper using the mark "1" as a mark. Thus, the mounting piece 83a is completely separated from the lid 80 and is fixed to the box main body 110 by the one-way screw 140. That is, the lid 80 with respect to the box body 110
Are released, 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 6 is removed.
Perform the inspection of 1. Also, by removing the lid 80 (cutting the connecting portions 84a and 85a), each of the equipment holes 1 is removed.
The one-way screw 140 inserted through 35 to 137 is ready to be taken out, and the one-way screw 140 inserted through 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, with the lid body 80 covered on the box main body 110, the removed one-way screw 140 is engraved with the mark "2" as a mark. 83b is screwed into the mounting hole 86b. Thus, the mounting hole 86b of the mounting piece 83b and the corresponding mounting hole 132 of the body frame 116 are formed.
Are tightened together by the one-way screw 140, and the circuit board box 62 is restored to the closed state again.

The above-mentioned inspection work of the circuit board 61 is performed by a salesman on the maker side of the circuit board box 62, and the salesman writes his / her name (inspector) and the inspection date on the inspection history seal 91. By doing so, the fact that the inspection has been performed is clearly indicated on the circuit board box 62. Furthermore, by inputting the board number, the inspector, the inspection date, the data input person, and the like into the management computer on the manufacturer side, it is possible to determine whether the description on the inspection history seal 107 is legitimate. . As a method of inputting such inspection history data, a network is formed between the hall computer, the management computer of the manufacturer, and the terminal computer of the sales office, and the data content input at the sales office is recorded on the management computer. . Then, the inspection history data may be read from the management computer and browsed based on data such as the board number input from the hall computer.

Thereafter, when the circuit board box 62 is to be inspected again (second inspection), the connecting portions 84b and 85b are cut using the mark "2" as a mark. As a result, the mounting piece 83b is separated from the lid 80 and the circuit board box 6
Release 2 Thereafter, similarly, 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 is screwed into the mounting hole 86c of the mounting piece portion 83c with the mark "3" as a mark. . Thereby, the circuit board box 62 is restored to the closed state again. Thereafter, when the circuit board box 62 is inspected (the third inspection), each connecting portion 84 is marked with the mark “3” as a mark.
c. 85c is cut to attach the mounting piece 83c to the lid 8.
0 and the circuit board box 62 is opened. When the circuit board box 62 is restored, each connecting portion 84
One-way screw 1 that was taken out along with the cutting of c and 85c
The 40 (one-way screw 140 of the equipment hole 137) is screwed into the last remaining mounting hole 86d.

By the way, the above-mentioned circuit board box 62
In the closed state, the connecting portions 84a to 84c and 85a
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.

The game control circuit board 61 housed in the circuit board box 62 is, as shown in FIG.
The wiring 167 is connected to the various connectors 75, and the wiring tubes 168 are attached to the wiring 167 for each of a plurality of connectors 75 each including one connector 75. The wiring tube 168 is made of a colorless and transparent vinyl, and protects the wiring 167 from outside by bundling a plurality of wirings 167 and covering the outer periphery of the wiring 167. For this reason, even when an illegal board is connected to the wiring 167 and is concealed in the wiring tube 168, the illegal part can be easily found through the colorless and transparent wiring tube 168.

As described above, the circuit board box 62 according to the present embodiment is provided with the one-way screw 140 for fastening the box body 110 and the lid 80 in an irreversible (unremovable unless broken) fixing state. One-way screw 1
Forty heads 141 are made of irreversible ultraviolet curable resin 170
It is covered with. For this reason, the one-way screw 14
In order to destroy 0, the ultraviolet curable resin 170 covering the one-way screw 140 must be destroyed. Therefore, the trace of destruction of the ultraviolet curable resin 170 remains as a trace of breaking the one-way screw 140, so that
An improper act can be immediately discriminated, and an improper act on the game control circuit board 61 can be prevented. Further, since the ultraviolet curable resin 170 covering the one-way screw 140 is transparent, the one-way screw 140 is
Can be confirmed through. Further, the ultraviolet curable resin 170
Has the property of being cured in a few seconds by irradiation of ultraviolet light, so that the one-way screw 140 is
Work can be performed quickly.

An advantage of using the ultraviolet curable resin 170 as a sealing member for covering the one-way screw 140 is that the one-way screw 140 is securely cured by the ultraviolet-curable resin 170 because the resin is not cured unless irradiated with ultraviolet light. It can be cured after confirming that it has been covered. Also,
Unlike a seal, the solution does not reduce its adhesive strength.

The above embodiment (first embodiment)
Does not limit the present invention, and various modifications are possible within the scope of the present invention. Hereinafter, other configurations will be described as second and third embodiments. In the following description, the same components as those in the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted.
In the second embodiment, as shown in FIG.
The hologram seal 104 covers the portion of the box body 110 where the screw 140 is stopped. In this configuration, if the one-way screw 140 is to be illegally destroyed, the hologram seal 104 covering the one-way screw 140 must be peeled off. Therefore, since the hologram design of the hologram seal 104 remains as a trace of breaking the one-way screw 140, an improper act can be immediately discriminated. In the second embodiment, the one-way screw 140
Is inserted into the recess of the upper plate 81, and the hologram seal 104 is attached to the outer peripheral surface thereof. For this reason, the hologram seal 104 is stuck on a flat surface (not stuck directly on the head 141), and a good stuck state is obtained.

In the third embodiment, as shown in FIG. 14B, no recess is formed in the mounting holes 86a 'to 86d' of the upper plate 81, and the head 141 of the one-way screw 140 is connected to the upper plate 81. Is provided to protrude from the outer wall surface. The ultraviolet curable resin 170 is cured so as to cover the protruding head 141. As described above, in the third embodiment, the one-way screw 140 is coated by applying the ultraviolet curable resin 170 directly to the outer periphery of the head 141 instead of injecting the ultraviolet curable resin 170 into the concave portion. . However, the configuration in which the ultraviolet curable resin 170 is injected into the concave portion as in the first embodiment can surely cover the one-way screw 140 in a fixed amount. Also,
As the sealing member, a transparent adhesive or the like may be used in addition to the ultraviolet curable resin and the hologram seal described above. That is,
When the sealing state by the sealing member is released, any member may be used as long as the trace remains.

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 board box of the present invention is a circuit board box for storing a game control circuit board, but the present invention is not limited to this. For example, a board box for storing a prize ball payout control board or the like may be used.
That is, any board box that needs to prevent improper acts on the internal circuit board may be used. Further, the materials forming the various constituent members are not particularly limited to those described in the embodiment. For example, the transparent upper plate may be formed of a glass material instead of a transparent synthetic resin. Further, the fastening means for fastening the substrate box is not limited to the one-way screw, but may be a rivet or a breaking screw. The material of the substrate box is not particularly limited, and may be a synthetic resin or a metal. Further, in the embodiments, the case where the present invention is applied to a ball-and-ball game machine is illustrated, but a game machine such as a slot machine, a video pachinko game machine, or a coin game may be used.
