ABSTRACT:
An electricity turning-on control device having a main control section, a main-power source, a power source switch, an operation panel control section, a sub-power source. The main control section has a RAM for storing information regarding an input/output interface and a CPU having a high clock frequency. The operation panel control section has a CPU having a low clock frequency. When no predetermined detecting signal is detected by the operation panel control section for a predetermined time, the power source switch is switched to the electricity turning-off state, thereby turning off supply of electric power to the main control section. On the other hand, when the predetermined detecting signal is detected, the power source switch is switched to an electricity turning-on state, thereby turning on supply of electric power to the main control section, and the main control section establishes a condition regarding the input/output interface on the basis of the information stored in the RAM.
