Abstract

PURPOSE:To make automatically correct inconsistency in display system due to shocks of miscellaneous signals by synchronizing mutually an electro-optical display system with an analog system in every specific period. CONSTITUTION:In normal operation time, the frequency dividing signal of a watch is counted by a preset counter 10, and a time indication 12 is carried out through a decoder 11. When a specific time or date is detected 13 from a decoder 11, a preset signal circuit 9 is operated by this sampling signal. Simultaneously, the transistor 21 of an ebcoder 20 is turned on to luminate luminescent diodes 22 through 25, code light which has passed a photo-cooling plate 30 synchronizing with hands is received by photo-transistors 26 through 29, and a code signal is supplied to the preset counter 10. Then, the content of the preset counter 10 is synchronized with the photo-coding plate 30, that is, analog hands.
