It is an object to provide a game machine that can monitor the occurrence of a wrongful act or an abnormal situation at the power cutoff time when electric power is not supplied, thereby improving the security of the game machine. A second backup electric power source (124) supplies electric power to a clock module (141) when an electric power source unit is in a turned-off state. A door operation signal generating circuit (131), which detects whether a door unit is open or closed to output a door operation signal, is supplied with the electric power from the second backup electric power source (124), so that it is always operable. A controller (149) in the clock module (141) generates time and date information (door operation information) when the door is open or closed in accordance with the door operation signal from the door operation signal generating circuit (131) and an SRAM (148)stores it. In the case where the electric power source is in the turned-on state, a CPU (123) makes an image display unit display the contents of the door operation information when the CPU receives a detected signal from an open-closed state confirming button operation detecting sensor (82). |
