PROBLEM TO BE SOLVED: To provide a game machine which enables easy confirmation of opening of a substrate box and is capable of suppressing a fraud carried out to the substrate box.SOLUTION: A substrate box 100 is provided with a base protrusion 158 being undetachably secured with a cover protrusion 177 by adhesives, so that the substrate box 100 may not be opened unless the base protrusion 158 is cut together with the cover protrusion 177. As a result, a trace of opening the substrate box 100 is left clearly, and thereby hall staffs can easily confirm that the substrate box 100 is opened by confirming a breakdown situation of a base sealing part 157 and a cover sealing part 176. Also, the substrate box 100 is configured to easily find an opened state, so that the occurrence itself of a fraud performed to the substrate box 100 can be suppressed. |
