Abstract

PURPOSE: To always precisely display the state of power supply and a device by driving and controlling plural display elements including display elements displaying the specified power supply state of the device regardless of the on/off state of the power supply of the device.
CONSTITUTION: Power control PC-CPU 30 which is always in an operation state even if device power supply is in the on/off-state, a circuit transmitting power supply state information of the device to PC-CPU 30, a circuit 28 controlling operation power in the device in accordance with output information of PC-CPU 30 and a circuit driving and controlling plural display elements including the display elements displaying the specified power supply state of the device even if the device power supply is in the on/off states in accordance with output information of PC-CPU 30 are provided. Thus, the supply state of operation power supply and the state of the device can always be recognized when the device is used by an AC adapter 29 and when the device is used by an internal battery. Thus, the stable power supply state is always maintained, and the state of power supply and the device can securely be displayed and recognized for an operator even if the power supply of the device is in the on/off state.
