Abstract
A portable terminal device has a timer directly transmitting a signal to a displaying circuit. The displaying circuit directly receives the signal from the timer at set time intervals to update time display of a display part. The control part of the portable terminal device need not be started to update the time display. The battery consumption of the portable terminal device can be reduced. The time display can be updated when the portable terminal device is in a power conservation state.
