BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing unauthorized access to a control board storage box in a pachinko machine.

[0002]

2. Description of the Related Art Conventionally, various measures have been taken in a control board storage box for storing a control board in order to prevent unauthorized modification of a control board, for example, replacement of an unauthorized ROM. The cover body is fixed to the case body with screws, and a sticker with a control number is attached between the two to prevent the cover body from opening itself and prevent unauthorized modification of the control board. In the unlikely event that the cover is opened and tampering is performed, the fact that the seal has been broken can be easily found because the seal has been cut. It has been determined whether or not a proper control board storage box is attached by checking the assigned management number with a game board number sticker attached to, for example, a lower right corner of the pachinko machine. However, in this conventional method, since the cover can be opened only by peeling off the sealing seal, there is a problem that the control board can be tamper-modified with relative ease. If the sticker is cleverly reattached, there is a problem that it becomes difficult to detect the fact of tampering. So, for example, (a) if the control board storage box is forcibly opened, the case body and the cover body will be damaged so that the control board cannot be tampered with. The remaining ones (Japanese Patent Application No. 9-21638) have been developed.

A management number sticker 111 is attached to a management number sticker sticking portion 110 of the top plate of the cover body 104,
Further, an opening history seal 113 is attached to the serial number seal attaching portion 112. This opening history seal 113
The date when the opening section 108 was cut and opened (by the store manager or by the police) is recorded. The date of the opening is also recorded by the store manager (police) in the resume. By doing so, it is possible to check whether the opening has been illegally performed by comparing the date of the opening history seal 113 with the date of the history record recorded by the store manager (police).

However, even in the case of (b), there is a possibility that fraud is performed in the following procedure. In this case, as shown in FIG. 13, the first opening is performed, the first A sealing portion 107 is cut, and the sealing screw 109 of the second B sealing portion 107 is fastened and sealed. It is assumed that Peel off the management number seal 111 and the opening history seal 113. The control board 103 is taken out by cutting off the unsealing part 108 of the second B sealing part 107 of the sealing part group 106 of the control board storage box 101. The control board 103 is illegally remodeled. On the other hand, a new control board storage box 101 is obtained by cross-flow from a trader or is used for another machine. Cut the opening 108 of the first A sealing portion 107 of the control board storage box 101 obtained in step 2, take out the control board 103 in the box, replace it with the modified unauthorized control board in step 2, and seal the second B Fasten the screw 109 and seal. The control number sticker 111 and the opening history sticker 113, which have been peeled off, are attached to their original positions. By doing so, the control board storage box 101 can be illegally remodeled, and there is a problem that the illegality cannot be found. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a sealing portion between a case body and a cover body of a control board storage box, which cannot be opened with a breaking screw, and a control unit attached to the cover body. It is an object of the present invention to provide a structure for preventing a control board storage box from being fraudulent on a control board by preventing the number sheet from being removed.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problem, the present invention provides a control board storage box having a sealing portion group including a plurality of sealing portions.
The control number sheet is fixed to an appropriate position of the cover body of the control board storage box by a fixing means. The invention according to claim 2, wherein the fitting fixing means includes a fitting recess formed in the cover body. A recess is provided, and a closing member is fitted into the fitting recess.

FIG. 1 shows an embodiment of the present invention.
3, the control board storage box 10 according to the present embodiment includes a case body 12 that houses a control board 11, and a cover body 13 that is openably and closably attached to the case body 12 and covers the control board 11. And As is well known, the control board storage box 10 is detachably connected to a back cover (not shown, which corresponds to an accessory protection cover or a back mechanism plate, etc.) attached to the back of the game board of the gaming machine. It is installed on the back side of the game board. FIG. 1 is a plan view of the control board storage box 10, and FIG. 3 is a plan view of the case body 12 alone. Therefore, when viewed from the back side of the game board in a plan view, the control board storage box 10 looks as shown in FIG. 1, and the front side is the cover body 13 and the back side is the case body 12.

As shown in FIG. 3, the case body 12 has a substantially rectangular plate shape, and has a side wall 12a on an outer peripheral portion thereof. Each of the four corners of the case body 12 has a prepared hole 1
Bosses 14 having 4a are formed respectively. The boss 14 at the lower left in FIG. 3 is set as a reference boss for fixing the cover, and the remaining bosses are set as mounting bosses for fixing the substrate.

On the left and right side surfaces of the case body 12, a pair of upper and lower locking pins 15 are projected. The locking pins 15 are respectively engaged with engagement holes (not shown) of left and right set plates 16 (see a two-dot chain line in FIG. 1) arranged on the back cover of the game board. With the engagement between the locking pins 15 and the set plate 16, the control board storage box 10 is supported by the back cover of the game board.

As shown in FIG. 1 and FIG.
Has a control board 11 housed therein with almost no gap. The control board 11 has a mounting surface 11a on the front surface and a solder surface 11b on the back surface. The mounting surface 11a has a ROM 1
8. In addition to various connectors 19, RAM, IC,
Components such as fuses are mounted. A shield plate 20 made of a conductive material such as punched metal is interposed between the case body 12 and the control board 11 (see FIG. 2).
The shield plate 20 blocks static electricity due to rolling friction of the game ball and the like, and prevents generation of noise due to the influence of the static electricity on the electronic components of the control board 11.

The control board 11 is fastened at its four corners by fixing screws 21 formed of tapping screws which are screwed into lower holes 14a of the bosses 14 of the case body 12. The lower fixing screw 21 in FIG. 1 also serves as a cover fixing reference screw for fixing the cover 13. The cover body 13 is formed in a substantially square shape smaller than the case body 12 so as to expose the left edge and the lower edge of the control board 11, and has a side wall 13a on the outer periphery thereof (FIG. 2). reference). The tip of the side wall 13a forming the left side and the lower side of the cover body 13 is in contact with the control board 11, and the side wall 13a forming the upper side and the right side of the cover body 13 is the side wall 12a of the case body 12. And a series of side walls are formed.

Various connectors 19 are arranged on the mounting surface 11a of the control board 11 which is not covered by the cover 13. In addition, R on the mounting surface 11a of the control board 11
The OM 18 is covered with a rectangular box-shaped ROM cover 23 by fitting, and further covered by the cover body 13. The upper surface of the ROM cover 23 is in contact with the cover 13.

A recess 24 is provided in the side wall 13a forming the left side surface of the cover 13. A heat radiating member (heat sink) 2 having a heat source that generates a large amount of heat such as a power transistor on the control board 11 is attached to the recess 24.
5 are exposed, and the heat radiation effect is enhanced. The cover body 13 is provided with a large number of small-diameter heat radiation holes 26 for releasing heat generated inside the control board storage box 10.

As shown in FIG. 1, a sticking portion 27 of an opening history seal 56 is set at the center of the front surface of the cover 13. A mounting hole 28 for a probability change key switch is provided in the lower right part of the front of the cover 13. At the upper right part of the front surface of the cover 13, a mounting part 29 of the management number sheet 55 is set in a part located above the ROM 18 (see FIG. 2).

As shown in FIG. 1, the cover body 13 is provided with a total of four positioning holes 33 of upper, lower, left and right having a diameter larger than the heat radiation holes 26. The positioning hole 33 is formed in a so-called concave shape with a bottom that does not penetrate.
This is for the purpose of minimizing the intrusion of foreign matter into the control board storage box 10, and prevents unauthorized modification by wires or the like from the positioning holes 33.

On the other hand, a positioning projection 34 protruding from the lower surface of the case body 12 is located on the same axis as the positioning hole 33 (see FIG. 2). For this reason, for example, when a plurality of control board storage boxes 10 are stacked, the positioning protrusions 34 of the upper control board storage box 10 engage with the positioning holes 33 of the lower control board storage box 10, thereby controlling the control board storage box 10. Load collapse of the substrate storage box 10 can be prevented. This is effective when the control board storage box 10 is transported, when the gaming machine is stored in an assembly factory, or the like. Also, the control of the gaming machine becomes complicated, and the control board 1
If it is necessary to increase the area of the control board 1, it is difficult to accommodate the control board 11 in a limited space on the back side of the gaming machine if one control board 11 is used.
It is conceivable to divide the positioning holes into a plurality of pieces. However, when the same control board storage box 10 is stacked and mounted on a game machine without making a special control board storage box 10, the positioning hole is used. The positioning function by the engagement between the positioning projections 34 and the positioning projections 34 can advantageously prevent mutual displacement.

The positioning projection 34 prevents the collapse of the control board storage box 10 when the control board storage box 10 is stacked, and also allows the control board storage box 10 to be mounted on the back surface (specifically, a protective cover or the like) of the game machine. It also has a function of securely holding the control board storage box 10 when it is mounted via. That is, since the set plate 16 usually has flexibility, when the positioning projection 34 is not provided, the set plate 16 is bent by an external force from the lateral direction (the horizontal direction in FIG. 1) of the control board storage box 10. As a result, the control board storage box 10 may come off from the protective cover or the like. For this reason, a hole for engaging with the positioning projection 34 is provided on the protective cover or the like, and the control projection is engaged with the hole of the protective cover when the control board storage box 10 is attached to the protective cover or the like. It is possible to prevent the substrate storage box 10 from falling off due to a lateral external force.

Next, as shown in FIG. 1, an appropriate number of sealing portion groups 36 are arranged on the side surface of the control board storage box 10. In the present embodiment, the sealing portion groups 36 are set at a total of three locations: the upper central portion, the lower right portion, and the lower left portion of the control board storage box 10. Each sealing section group 36 includes a plurality (four in the figure) of sealing sections 37 that can be sealed by sealing screws 38. Since each of the sealing unit groups 36 has the same configuration, the sealing unit group 36 at the lower right side in FIG. 1 will be described in detail with reference to FIGS. 4 to 9, and the description of the other sealing unit groups 36 will be omitted. .

(Second Embodiment) In the second embodiment, the control number sheet mounting portion 29 of the cover 12 is
As shown in the figure, a fitting recess 61 is formed to be able to fit a management number sheet 55 having a management number with a substantially rectangular shape, and the narrow side of the fitting recess 61 corresponds to the groove. 62 are formed. Also, the fitting recess 6
A locking portion 64 is formed in the closing member 63 to be fitted into the groove 1 so as to be fitted and locked in the groove 62. In the fitting recess 61 thus formed, the control number sheet 55 is accommodated along the bottom 61a with the control number facing upward, and the closing member 63 has the locking portion 64 and is locked in the groove 62. To be fixed on the same surface.

As described above, the control number sheet 55 is inserted between the fitting member 61 having the dovetail groove 62 and the closing member 63 having the locking portion 64 which engages with the groove 62. Since the closing member 63 cannot be removed from the dovetail groove 62, the control number sheet 55 cannot be taken out. Therefore, a new control board storage box or a control board storage box of another machine cannot be used. It is possible to prevent improper use of the substrate 11 and find an improper substrate as in the first embodiment.

In the second embodiment in which the control number sheet 55 is attached and fixed, the control number sheet 55 is
And a locking member 64 having a locking portion 64 which engages with the groove 62 in the fitting concave portion 61 having the shape described above. However, the present invention is not limited to this.
May be attached as in the first embodiment.

As described above, in the embodiment of the present invention,
In the control board storage box 10 having the sealing portion group 36 composed of a plurality of sealing portions 37, the control number sheet 55 is fixed to the control body sheet mounting portion 29 of the cover body 13 by, for example, being fitted and fixed. This fitting means secures the fitting recess 57 in the cover body 13 and the closing member 5 fitted in the fitting recess 57.
