PURPOSE:To display information on alarm time by supplying a source voltage to a time display part even if an ignition switch is off when an alarm setting means is operated. CONSTITUTION:A transistor 21 turns on and the source voltage of a battery 17 is supplied to a power source 14 for display when an alarm set switch 30 is operated. The alarm time based on the output from an up-down counter 32 conforming to the number of operations of the switch 30 is consequently displayed on an alarm time display part 33b. The time display part 33a and alarm time display part 33b of the display part 33 can be thus driven even if the ignition switch and lighting switch are not operated and therefore the present time and the alarm time are displayed even during the time when the driver is going to have a short sleep after setting the timepiece at the alarm time display mode. |
