<p>The present invention is to provide a game machine containing unlawful action prevention means which can be manufactured at a low cost and can easily detect an unlawful action. Flange portions 12a, 12b and 13a, 13b are respectively formed on a first case 4 and a second case 5 capable of receiving a control substrate by being closed against each other, while a micro-chip MC is inserted into holes 13aa, 13bb formed in the flange portions 13a, 13b. Each micro-chip MC includes a transparent substrate MCa secured in the holes 13aa, 13bb, and has an information recording layer MCb, a reflection layer MCc, a protection layer MCd, and an adhesion layer MCe, all laminated on the transparent substrate MCa. The adhesion layer MCe will be adhered to the surface of the flange portions 12a, 12b upon closing the first and second cases 4, 5. When the first and second cases are opened by an unlawful person, the recording layer MCb and the reflection layer MCc formed on the micro-chip will leak off and be damaged, thereby rending it possible to easily find an unlawful action by seeing the damaged portion through the transparent substrate MCa.</p> |
