Abstract
PURPOSE:To enable display contents to be effectively discriminated in a dark place where the display contents are not identifiable by illuminating the display part when the specified time having been stored in a memory circuit had been reached. CONSTITUTION:For example, 12 o'clock 58 minutes are set in a memory circuit 12 by operating a switch 10. And when the contents of a counter 8 become 12 o'clock 58 minutes upon lapse of time, the coincidence signal of the memory circuit 12 and counter 8 is emitted from a discrimination circuit 11 and this signal is inputted to a lamp drive circuit part D, then a lamp 9 goes on to illuminate the display part A.
