[0030]

According to the present invention, a circuit board storage box having a sealing structure for a gaming machine according to the present invention is a unit for mounting a unitized electronic device circuit such as a semiconductor substrate which must not be replaced, for example, a CPU, a ROM, a RAM, and the like. A container / mounting body called a box, which is a body and must be disassembled in order to replace the mounted electronic device, is sealed. The sealing means for the sealing is
It is formed from a plurality of components. The plurality of components are, for example, a combination of a lid and a container body, a bottom and a container body, a part of a lid and a part of a bottom. Both components form a substantially continuous surface, for example a plane, orthogonal or curved surface.
The term substantially means that there is a gap between the two components.

In the sealing process, when the component is disassembled, the sealing means is destroyed to make it difficult to reproduce the sealing means, and when the sealing means removed from the component is returned to the component, the sealing between the component and the sealing means is performed. This includes making it difficult to reproduce the positional relationship between them. For example, a process in which a score line is inserted in the sealing means and the sealing means itself is destroyed so as to be difficult to reproduce, and a process in which so-called marking processing is performed between the component parts and the sealing means to make it difficult to reproduce the positional relationship between the two. included. The sealing means may be cut only at the cut line, or the end of the cut line may be short-circuited with the end of another cut line to break at a position other than the cut line.

In the marking by welding, the joining of the sealing member and the component and the marking can be simultaneously performed. Such simultaneous processing makes reproduction more difficult. In the case of laser welding, it is easy to change the position of the markings such as characters and patterns, and it is easy to change the engraving form of characters and patterns, but it is necessary to reproduce the marking side individually. Yes, making reproduction more difficult.

A hologram sheet can be used as the sealing means. Reproduction of holograms that are difficult to create is extremely difficult. Copying the hologram itself is not possible with current technology. It is practically impossible to duplicate a three-dimensional reproduced image and reproduce a hologram corresponding to the three-dimensional image. In the case of using such a hologram, the reproducing person must reproduce the marking process and the destruction process as they are. Such a reproduction, that is, a reproduction using the destroyed sealing means itself (not a duplicated one but itself) and imitating the stamping processing and the destruction processing in its entirety is practically impossible.

Since it is difficult to reassemble and reassemble the box sealed according to the present invention after disassembly, replacement of the electronic equipment circuit can be substantially prevented. It becomes difficult to individually change programs and stored information of a gaming machine in which the same model is mass-produced and used. If changed, the fact of the change will be revealed.

, The cut line 54 also serves as the marking process ST1.

The cut line 54 indicates the box 1 and the sealing means 2
, And extends to both regions. The break line 54 is a wavy line such as a zigzag shape that is difficult to reproduce.
The stamping process ST1 extends to both areas across the boundary between the box 1 and the sealing means 2, that is, the contour 55 of the sealing means 2. The characters, figures, patterns, and symbols of the tally are difficult to duplicate. The cut line 54 is orthogonal to the longitudinal direction.

As shown in FIG. 5 (b), a display form for marking and a display form such as a cut line are performed by laser marking processing. Engraving is also a kind of sealing process. If the sealing means 2 is a transparent body, a light beam 56 as a laser is focused on the joint surface between the box 1 and the sealing means 2. In this case, the sealing means 2 can be welded to the box 1 by melting the surface of the resin forming the box 1.
