In addition, the main body side engaging portion 110 is composed of a separate main body side accommodating portion 111 and a main body side engaging auxiliary member 130, and the lid side engaging portion 120 is separate from the separate lid side accommodating portion 121 and the lid side engaging portion. Since the auxiliary member 140 is configured, it is more difficult to duplicate the main body side engaging portion 110 and the lid side engaging portion 120 (that is, the case main body member 60 and the case cover member 70), and anti-fraud can be suppressed. .
[0091]
Furthermore, the material of the main body side accommodating portion 111 and the lid side accommodating portion 121 is a transparent resin material, whereas the material of the main body side engaging auxiliary member 130 and the lid side engaging auxiliary member 140 is the main body side accommodating portion 111 and Since it is a colored translucent resin material different from the lid-side housing 121, the main body-side housing 111 (and the lid-side housing 121) has a regular body-side engagement assisting member 130 (and the lid-side engagement assisting member 140). Can be easily determined, that is, whether or not the case body member 60 (and the case lid member 70) is a duplicate.
[0092]
Further, the inner guard rib 64 of the case main body member 60 and the outer guard rib 78 of the case cover member 70 are connected to the edge of the case cover member 70 (outer guard rib 78) and the edge of the case main body member 60 (edge contact portion 65). When a tool (not shown) such as a wire or a cell plate is inserted into the case through the gap, a small gap is generated between the outer guard rib 78 of the case lid member 70 and the case body. Since it has to pass through a slight labyrinth-shaped gap formed between the inner guard ribs 64 of the member 60, it is possible to prevent tools such as wires and cell plates from being illegally inserted into the case. .
[0093]
Further, the substrate contact portion 79 formed on the case lid member 70 is in contact with the edge of the main control board 51, and the surface of the main control board 51 that faces the case lid member 70 is covered with the case lid member 70. Since the main control board 51 is attached to the inner surface side of the case lid member 70, even if a tool such as a wire or a cell plate is inserted into the case from the gap between the case main body member 60 and the case lid member 70, these Since the tool cannot reach the surface of the main control board 51 that faces the case lid member 70, it is possible to more reliably prevent an illegal act on the main control board 51.
[0094]
Further, since the peripheral rib 83 of the inner cover 80 contacts the edge of the main control board 51 and the surface of the main control board 51 facing the case main body member 60 is covered with the inner cover 80, the case main body member 60. Even if a tool such as a wire or a cell plate is inserted into the case through a gap between the case cover member 70 and the case cover member 70, these tools are not included in the main body of the main control board 51 (in addition to the surface facing the case cover member 70). Since the surface facing 60 cannot be reached, it is possible to more reliably prevent an illegal act on the main control board 51.
[0095]
Further, by using an ABS resin as a material for the main board case 55 (the case body member 60 and the case lid member 70), when a cutting operation is performed on the connecting portion 125, butadiene which is a component of the ABS resin has a rubber property. Thus, since the member is easily whitened without being cracked, the effect of clearly leaving the cut traces is obtained. Further, even if the main board case 55 is forcibly opened, there is an effect that the member is similarly whitened and the trace is easily left clearly.
[0096]
In the above-described embodiment, the inner guard rib 64 is formed inside the edge portion of the case body member 60, the outer guard rib 78 is formed outside the edge portion of the case lid member 70, and the outer guard rib 78 is the inner guard rib 64. However, the present invention is not limited to this, and as shown in FIG. 22, the outer edge of the case body member 60 is located outside the edge of the case body member 60. The outer guard rib 268 is formed on the inner side of the case lid member 274 and the inner guard rib 274 is formed on the inner side of the edge portion of the case lid member 70, and the outer guard rib 268 is positioned on the outer side of the inner guard rib 274. H.275 may be contacted.
[0097]
