PROBLEM TO BE SOLVED: To provide a technique capable of preventing easily and effectively an illegal action using a mode checker. SOLUTION: Electric power supply from a backup electric power source to a RAM of a main control panel is executed through a harness for connecting a door panel and the main control panel, when breaking the electric power source. A data of the RAM is cleared thereby since the electric power supply from the backup electric power source to the RAM is broken when returned from the mode checker to the door panel, even if the mode checker is attached instead of the door panel to store a game condition advantageous for a player (for example, bonus internal winning) into the RAM. The illegal action by the mode checker is prevented as a result thereof. COPYRIGHT: (C)2011,JPO&INPIT
