PURPOSE: To simplify constitution and improve reliability by scanning a matrix consisting two columns of electrodes with out-of-phase pulses and detecting the display position of a hand, and using driving pulses of a motor as the scanning pulses.

CONSTITUTION: A motor is driven with the driving pulses from a driving circuit DR to step-advance the hand. For example, when the hour hand indicates one o'clock, contacts a1 and a2 of a contact piece A contact electrodes ES1 and EC1 to conduct terminals S1 and G1, and a pulse from a terminal (a) is supplied to an output circuit EN1 through buffers F1 and F4 to generates a code output indicating one o'clock by the output circuit EN1 by using said pulse and a pulse from the buffer F1. Similarly, the contact piece A rotates to make connections between outside electrodes ES1WES4, and inside electrodes EC1WEC3, and contacts of the matrix are made successively, so that the output circuit EN1 generates code outputs corresponding to 2W12 o'clock successively. Then, time casting is performed corresponding to the display time on the basis of said code outputs.
