PROBLEM TO BE SOLVED: To provide a game machine capable of notifying the propriety of a reuse of a predetermined component provided in the game machine. SOLUTION: When a pen type detector 100 is connected to a display control board D, a drive voltage is supplied to an MPU (a microprocessor unit) 31. The connection of the pen type detector 100 is recognized by a signal output circuit 71 through an input of a low signal in an SWP 1 terminal (SWP 2 terminal). When recognizing the input of the low signal, the MPU 31 determines the propriety of the reuse of a liquid crystal panel 52 (a backlight 54) and outputs a high signal from an input/output port 39 to a connector 85a (a connector 85b). The high signal is thus input in the pen type detector 100 and either one of light emitting diodes D3 and D4 provided in the pen type detector 100 emits a light. COPYRIGHT: (C)2009,JPO&INPIT
