PURPOSE:To make it possible to call and display a time which is stored in order successively from the time following the current time by providing a magnitude comparator which compares a prescribed time with the current time. CONSTITUTION:Time stored in an RAM1 is compared with the current time on a fundamental timepiece 2 by the magnitude comparator 3; and when the first contents of the RAM1 larger and the contents of the are changed to obtain enlarged comparison, an output signal is outputted from the magnitude comparator 3 to operate a control circuit 4, and a pulse to an address counter 6 is stopped. The comparison between the contents of the RAM1 and the current time on the timepiece 2 is always performed, and contents of the RAM1 are stored in a display control circuit by the output signal of the magnitude comparator 3, and times following the current time are displayed on a display panel 8 when a display call signal 5 is inputted. |
