Usually, the electronic circuit includes electronic components such as a central processing unit (CPU) for performing general arithmetic control, a storage element (RAM) capable of reading and writing data, and a storage element (ROM) capable of reading only data. Provided. The CPU controls the operation of the accessory of the ball-and-ball game machine and the reel of the slot machine using the RAM and the ROM.

[0003] The jackpot occurrence probability in this type of gaming machine is determined by random lottery. That is, the random number generated by the random number generator is sampled, and the winning mode is determined based on which section of the winning determination table has the sampled random number value. The winning determination table is made up of data for dividing a certain range of random numbers into respective winning modes, and is stored in the ROM. The CPU generates a large hit if the sampled random number value belongs to the section A of the winning determination table, generates a small hit if the sampled random number value belongs to the section B, and generates a small hit if the sampled random number value belongs to the section C. Lost.

The ROM storing such data as the jackpot occurrence probability is detachably attached to the electronic circuit board and can be replaced. By replacing the ROM, it is possible to easily configure control circuit boards of different game models using the same electronic circuit board.

Since the ROM is detachable, the ROM is replaced with a modified ROM.
There is a situation in which data such as a jackpot occurrence probability is falsified and a large number of game balls, medals, and the like are illegally obtained.

Conventionally, in order to prevent such misconduct, R
A seal is attached to the electronic circuit board in a state of straddling the OM. In addition, a seal sticks over the body and lid of the board case that houses the electronic circuit board on which the ROM is mounted.

A ROM 47 storing jackpot probability information and the like is inserted into a socket 48 of the game board 42 shown in FIG. FIG. 3 shows a part of the ROM 47 in an enlarged manner. FIG. 3A is a plan view of the ROM 47, and FIG. 3B is a side view thereof.

As shown in FIG. 3, a seal 49 extends over the ROM 47 fixed to the socket 48 and the game board 4
It is stuck on 2. The sealing seal 42 is coated with an adhesive or a cured resin 50 at both ends. The adhesive or the cured resin 50 may be configured to cover not the seal seal 49 but the entire seal seal 49 as shown in the plan view of FIG.

In the conventional board case, since the two parts of the main body and the lid were simply connected and fixed by claws or screws, the board case could be easily opened by peeling off the sealing seal. However, as in the present embodiment, if the case body 41a and the case lid 41b are partially or entirely abutted with an adhesive or a cured resin 45 or are welded by ultrasonic waves or heat, Even if the sealing seal 46 is peeled off, the board case 41 does not open. For this reason, according to the present embodiment, it is difficult to expose and remove the game board 42 and to attach and detach the ROM 47.

In this embodiment, a seal 49 is further provided over the ROM 47, and both ends of the seal 49 are covered with an adhesive or a cured resin 50. For this reason, even if the board case 41 is opened by any means and the ROM 47 is detached, the sealing seal 49 is peeled off, and a trace remains. Therefore, it is immediately known that the illegal operation has been performed on the gaming machine, and it is possible to take a countermeasure.

Further, a sealing seal 4 extending over the ROM 47
When the entirety of 9 is covered with the adhesive or the cured resin 50, it is difficult to peel off the seal 49 itself, and it is also difficult to attach and detach the ROM 47. Accordingly, a double sealing structure is provided in combination with the sealing structure of the board case 41, and a sufficient countermeasure against unauthorized replacement of the ROM 47 is taken.

In the description of the above embodiment, the ROM 4
Although the case where a part or the whole of the seal 49 extending over 7 is covered with the adhesive or the cured resin 50 has been described, the following configuration can be adopted. That is,
A part or the whole of the ROM 47 is directly covered with a transparent adhesive or cured resin 50, and a seal 49 is attached to the game board 42 over the adhesive or cured resin 50.

When a part or the whole of the ROM 47 is directly covered with the adhesive or the cured resin 50 as in the present configuration, it is difficult to attach and detach the ROM 47 even if the sealing seal 49 on the ROM 47 is peeled off. It is. Therefore, also with this configuration, a double sealing structure is realized in combination with the sealing structure of the board case 41, and illegal replacement of the ROM 47 is effectively prevented.

Next, an electronic component sealing structure of a gaming machine according to another embodiment of the present invention will be described with reference to FIG. 2A and 2B show board cases 61 and 62 to which the electronic component sealing structure of the gaming machine according to the present embodiment is applied, FIG. 1A is a plan view of these board cases 61 and 62, and FIG. FIG. 4C is a front view of the board case 62, and FIG.

and a case lid 61b that is placed over the a. At each end of the case body 61a and the case lid 61b, engaging portions 61c and 61d each having a through hole 64 are formed. The case lid 61b includes the engaging portions 61c and 61d.
Of the case body 61 so that the through holes 64 opened in
a. An L-shaped fixture 65 is provided on the base 63, and the fixture 65 has a through hole 6.
A through hole having the same diameter as that of No. 4 is opened.

The board case 61 is provided with a binding band 66 in a through hole 64 of each of the engaging portions 61 c and 61 d and a through hole of the fixture 65.
Is inserted and fixed to the base 63. The binding band 66 is generally used for binding electric wires. When the end 66a of the binding band 66 is passed through the loop 66b, the loop 66 is inserted into the groove 63c cut in a ratchet shape.
b is caught, and the end portion 66a does not come off from the annular portion 66b.

The binding band 66 has a special color. In other words, most of the commercially available binding bands are black, white, and transparent, but the binding band 66 in this embodiment has a special color other than these commercially available colors. , Specially manufactured. Therefore, it is difficult for an ordinary person to obtain the binding band 66 having this special color. Note that an electronic component sealing structure having the same structure is formed at the opposite end of the substrate case 61.

As in the present configuration, the case body 61a covered with the case lid 61b has a binding band 66 of a special color.
When the binding case 66 is cut and the substrate case 61 is opened, the binding case 66 having the same special color cannot be obtained, so the base case 63 is again fixed to the original state. It is difficult. For this reason, the binding band 66 performs the function of a sealing seal, and by monitoring the state of the binding band 66, it is possible to grasp the trace of the illegal operation on the board case 61.

The board case 62 on the right side of the figure also includes a case body 62a for accommodating the game board 42, and a case lid 62b that covers the case body 62a. In addition, engaging portions 62c, 62 each having a through hole opened at each end of the case main body 62a and the case lid 62b.

Fixed. The screw 68 used for fixing the substrate case 62 has a special shape in the shape of the bit 68a at the head. In other words, most of the bit shapes of ordinary commercially available screws are plus (+) and minus (-), but the bit 68a of the screw 68
Has a special shape that commercially available screws do not have. Therefore, a tool having a head corresponding to the bit 68a is not generally sold, and a general person cannot turn the screw 68. An electronic component sealing structure having the same structure is formed at the opposite end of the board case 62.

As shown in the present configuration, the bit 6 having a special shape is used.
The board case 62 is fixed to the base 63 by the screws 68 having 8a.
Since it is difficult to turn the screw 68 when the screw 68 is stopped, the screw 68 screwed to the base 63 cannot be removed. Therefore, it is difficult to open the board case 62, and illegal operation on the game board 62 can be prevented.

The ROM 47 mounted on the game board 42 in each of the above-described board cases 61 and 62 is also sealed with each structure shown in FIG. 3 or the ROM 47 itself is directly bonded with an adhesive or a cured resin. By performing sealing with the above-described structure, a double sealing structure can be realized.
By taking such a double sealing structure, the ROM 47
Can be more effectively prevented.

[0054]

As described above, according to the present invention, it is difficult to detach the electronic component when the entire seal covering the electronic component is covered with an adhesive or a cured resin. If a part of the seal is covered with an adhesive or a cured resin, the seal remains when the seal is peeled off.

When a part or the whole of the electronic component is covered with an adhesive or a cured resin, it is difficult to detach the electronic component even if the sealing seal is removed.

When the case lid and the case main body are bonded to each other with an adhesive or a cured resin at a part or the whole of the contact portion, even if the sealing seal is peeled off, the case is not opened, and the electronic device is not opened. Removal of parts is difficult.

Further, even when the case lid and the case body are welded at part or all of the abutting portions, even if the sealing seal is peeled off, the case does not open, so that it is difficult to attach and detach the electronic components. is there.

Further, the case body covered with the case lid is fixed to the base by a binding band of a special color. When the binding band is cut and the case is opened, the binding band of the same special color can be obtained. Because of this, it is difficult to put the case back to its original state again.

Further, since the case body covered with the case lid is fixed to the base by a screw having a special bit shape, a tool having a head matching the special bit shape cannot be obtained. It is difficult. Therefore, the screw screwed to the base cannot be removed, and it is difficult to open the case.

For this reason, it becomes difficult to attach and detach the electronic component storing the jackpot probability information and the like, and even if it is detached, a trace of it remains. Therefore, the modification of the electronic circuit board that controls the gaming machine is effectively prevented, and a large amount of gaming media is not illegally stripped.
