Description

  The present invention relates to a game machine represented by a spinning machine (slot machine) and a ball game machine (pachinko machine).

  In recent years, fraudulent acts on gaming machines have become conspicuous. For example, there are cases where fraudulent acts are performed in which legitimate microcomputers are replaced with fraudulent microcomputers obtained by falsifying lottery data or game control programs. Such illegal microcomputers are made precisely so that they cannot be easily distinguished from each other even when compared with regular microcomputers. In order to prevent such an illegal act, a gaming machine has been proposed in which a trace of unsealing is left when a board case that accommodates a control circuit board is opened (see, for example, Patent Document 1).

  However, in such gaming machines, it is necessary to detect the mounting of illegal microcomputers and illegal electronic parts by opening traces. For example, if the traces are small and inconspicuous, check the gaming machines, etc. There was a possibility of overlooking misconduct. In order to solve such a problem, a gaming machine including a board case having a shape surrounding a regular microcomputer has been proposed (for example, see Patent Document 2).
