  Further, a board case (game machine board case) 30 is disposed inside the slot machine 10 (see FIG. 2). The board case 30 stores a control board (control board for gaming machine) (not shown) for driving and controlling each part of the slot machine 10, and in this embodiment, the board case 30 is disposed behind the upper door 10a, Arranged above the reels 20a to 20b.

  As shown in FIG. 2, in the present embodiment, the substrate case 30 has a front case 32 whose opening is directed to the rear of the slot machine 10 (hereinafter may be simply referred to as rear), and the opening is the slot machine 10. And a rear case 34 facing forward (hereinafter sometimes simply referred to as front). The front case 32 and the back case 34 are made of a transparent resin (plastic or the like), and a control board housed inside can be visually recognized.

  In the present embodiment, the front case 32 and the rear case 34 are pivotally attached to a hinge 36 provided on the left side (hereinafter sometimes simply referred to as the right side) toward the slot machine 10. As a fulcrum, a right side (hereinafter may be simply referred to as a right side) toward the slot machine 10 is provided to be rotatable forward and backward. Then, the substrate case 30 is opened and closed by turning about the hinge 36 as a fulcrum.

  On the right side of the front case 32, locking pieces 32a are provided on the upper part and the lower part, respectively. Also, on the right side of the back case 34, locking pieces 34a are provided on the upper part and the lower part, respectively. Furthermore, each of the locking pieces 32a and 34a is provided with an opening 38. The locking pieces 32a and 34a are formed so that the openings 38 overlap each other when the substrate case 30 is closed. Then, after the control board is accommodated in the board case 30, the locking pieces 32a and 34a are sealed by the sealing member 40, thereby preventing unauthorized access to the control board.

  The sealing member 40 includes a receiving member 42 and a fastener 44 that sandwich the locking pieces 32a and 34a from the front and rear by being attached to the locking pieces 32a and 34a so as to penetrate the opening 38. When the sealing member 40 is attached to the locking pieces 32a and 34a, the return claw of the fastener 44 is engaged in the cylindrical portion of the receptacle 42, and the sealing member 40 (the receptacle 42 and the fastener 44) cannot be separated. Become. By doing so, the substrate case 30 cannot be opened unless the sealing member 40 or the locking pieces 32a and 34a are destroyed.

  As described above, the substrate case 30 that cannot be opened unless the sealing member 40 and the locking pieces 32a and 34a are destroyed is provided with a hologram plate 50 indicating that the stored control board is a regular product. . In the present embodiment, the description will be made with an example in which the hologram plate 50 is arranged on the main body (substrate case main body) 39 (see FIGS. 3, 5, and 7) of the front case 32.

In FIG. 3 showing a cross section of the front case 32, a hologram plate 50 is a hologram original plate (not shown) duplicated (transferred) by electroforming or the like, and is formed of a transparent resin or the like. The hologram original plate is made of, for example, quartz, SiO ₂ / Si, or the like, and has fine unevenness (pixel size is about 0.5 μm to 1 μm, step height (maximum) is about 150 μm to 250 μm) that is visually recognized as a hologram. ) Is formed on the surface. And this unevenness | corrugation (hologram pattern) is transcribe | transferred by the single side | surface 52 (henceforth the hologram surface 52) of the hologram plate 50. FIG.

  Note that the number of steps of the hologram pattern transferred to the hologram original plate or the hologram plate 50 (the number of uneven portions) can be set as appropriate. As a specific number of steps, for example, 8 steps (indicating that irregularities with eight levels of height are formed) or 4 steps (indicating that irregularities with four levels of height are formed) And the number of steps.

  The hologram plate 50 on which the hologram surface 52 is formed as described above is formed integrally with the front case 32 by insert molding, which will be described later, with the hologram surface 52 facing the back side of the slot machine 10. . Thus, since the hologram plate 50 is formed integrally with the front case 32 when the front case 32 is manufactured, the hologram seal 50 is peeled off and reused as compared with the method of attaching the hologram seal after manufacturing the front case. Therefore, unauthorized actions such as unauthorized modifications to the control board can be more reliably prevented. Further, the trouble of attaching the hologram sticker can be omitted.

  Further, in the present embodiment, the hologram plate 50 is disposed on the front case 32 with the hologram surface 52 facing the back side of the slot machine 10 (see FIGS. 3, 5, and 7). That is, the hologram surface 52 is provided inside the substrate case 30 and is not exposed unless the substrate case 30 is opened. By doing so, the hologram surface 52 can be protected.

Hereinafter, as described above, a manufacturing method for manufacturing the substrate case 30 (front case 32) integrated with the hologram plate 50 will be described with reference to FIGS. As shown in FIG. 4, when manufacturing the substrate case 30 (front case 32), the hologram plate 50 is first manufactured. In manufacturing the hologram plate 50, first, the electroforming mold 62 is manufactured by taking a hologram original plate 60 formed of quartz, SiO ₂ / Si, or the like by electroforming (S1: electroforming manufacturing step).

  Next, a mold 64 with an electroforming mold incorporating the electroforming mold 62 is formed (configured) on the hologram plate forming mold 63 for manufacturing the hologram plate 50 (S2: mold forming step). The hologram plate forming mold 63 is provided with a recess corresponding to the shape of the electroforming mold 62 (electric mold fitting portion (reference numeral omitted)), and the electroforming mold 62 is fitted into this depression (electroforming mold fitting portion) ( As a result, the die 64 with an electroforming mold is configured. Then, for example, a transparent resin or the like is poured into the mold 64 with an electromold, and the hologram plate 50 is manufactured by peeling from the mold 64 with an electromold after curing (S3: Hologram plate forming step (integration step) )).

  Subsequently, the substrate case 30 (front case 32) is formed (manufactured) using the hologram plate 50 manufactured as described above. 5, the substrate case 30 (front case 32) is manufactured by insert-molding the hologram plate 50 (S4: case formation step (integration step). Specifically, the substrate case 30 ( A transparent resin or the like is poured into the substrate case forming die 65 in a state where the hologram plate 50 is disposed inside the substrate case forming die 65 for forming the front case 32), and after curing, the substrate case forming die. The substrate case 30 (front case 32) is manufactured by peeling from the mold 65.

  Thus, in the present embodiment, when the hologram surface 52 is formed integrally with the substrate case 30, first, the hologram plate 50 integrated with the hologram surface 52 is formed, and then the hologram plate 50 is integrated with the substrate case 30. It has become. That is, in this embodiment, the integration step for forming the hologram surface 52 integrally with the substrate case 30 includes two steps of “S3: Hologram plate formation step” and “S4: Case formation step”.

  Note that the present invention is not limited to the above-described embodiment and can be modified as appropriate as long as the hologram surface 52 is formed integrally with the substrate case 30. For example, in the above-described embodiment, an example in which the hologram surface 52 is directed to the back side (inside the substrate case 30) has been described. However, the hologram surface 52 may be configured to face the front side (outside the substrate case 30). .

  In the above-described embodiment, the example in which the hologram is provided in the front case 32 has been described. However, the hologram may be provided in the back case 34. Of course, a hologram may be provided on the side surface of the substrate case 30 so as to straddle the front case 32 and the back case 34. Further, a hologram may be provided on the sealing member 40 (one or both of the receiver 42 and the fastener 44).

Moreover, although the said embodiment demonstrated in the example in which the hologram surface 52 was exposed, this invention is not limited to this. For example, as shown in FIG. 6, a protective layer 70 covering the hologram surface 52 may be provided. The protective layer 70 is formed, for example, in a protective layer forming step in which a transparent paint is applied to the hologram surface 52. The protective layer forming step is performed after “S3: Hologram plate forming step” or “S4: Case forming step” (see FIGS. 4 and 5). By providing the protective layer 70 in this way, not only can the hologram plate 50 (hologram surface 52) be protected, but also the problem that the hologram plate 50 (hologram surface 52) is duplicated (transferred) by electroforming or the like can be prevented. .

  That is, if the hologram surface 52 is exposed to the outside, the hologram surface 52 can be transferred in the same manner as when the hologram pattern is transferred from the hologram original plate. On the other hand, since the protective layer 70 is provided in the present embodiment, the protective layer 70 needs to be peeled off from the hologram surface 52 in order to transfer the hologram surface 52. However, as described above, fine irregularities (hologram pattern) are formed on the hologram surface 52, and it is difficult to peel off the protective layer 70 without damaging the hologram surface 52 (that is, transferring the hologram surface 52). Difficult to do).

  If the protective layer 70 and the hologram surface 52 (hologram plate 50) are formed of optically homogeneous materials, the function of the hologram due to the unevenness (hologram pattern) of the hologram surface 52 is impaired. The protective layer 70 is preferably formed of a material having a refractive index different from that of the hologram surface 52 (hologram plate 50). In this example, the protective layer 70 is formed by applying a transparent paint. However, the present invention is not limited by the method of forming the protective layer 70. For example, the protective layer 70 is protected by printing. The layer 70 may be formed, or the protective layer 70 may be formed by attaching a transparent seal or the like to the hologram surface 52. Furthermore, you may form the protective layer 70 from the material provided with the UV cut function. By doing so, the hologram surface 52 can be protected from deterioration due to ultraviolet rays.

  In the above embodiment, when the hologram surface 52 is formed integrally with the substrate case 30, first, the hologram plate 50 integrated with the hologram surface 52 is formed, and then the hologram plate 50 is integrated with the substrate case 30. For example, the integration step for forming the hologram surface 52 integrally with the substrate case 30 includes two steps of “S3: hologram plate formation step” and “S4: case formation step” (FIG. 4, FIG. 5), the present invention is not limited to this. For example, as shown in FIG. 7, the hologram surface 52 may be formed integrally with the substrate case 30 (front case 32) in one step.

  In this case, initially, the electroforming mold 62 is formed in the same manner as in the method of FIG. 4 described above (S1: electroforming manufacturing step). Next, a mold 64 ′ with an electroforming mold in which the electroforming mold 62 is incorporated is formed (configured) with respect to the board case forming mold 65 ′ for forming the substrate case 30 (front case 32) (S2 ′: Mold construction step). The substrate case forming mold 65 ′ is provided with an electromold fitting portion (reference numeral omitted) that is a depression corresponding to the shape of the electroforming mold 62. As a result, a mold 64 ′ with an electroforming mold is formed.

  Then, for example, a transparent resin or the like is poured into the mold 64 ′ with an electroforming mold, and the substrate case 30 (front case 32) is manufactured by peeling from the mold 64 ′ with an electroforming mold after curing (S3 ′: Integration step). Thus, by forming the hologram surface 52 integrally with the substrate case 30 (front case 32) in one step, in addition to the same effects as in the above embodiment, it is possible to further reduce the labor and cost of manufacturing. An effect is also obtained.

  In the above embodiment, the example in which the present invention is applied to a slot machine as a gaming machine has been described, but the present invention is not limited to this. For example, the present invention may be applied to gaming machines other than slot machines such as pachinko machines. Of course, you may implement this invention combining the said embodiment and the various modifications mentioned above.
