Abstract

PURPOSE: To permit the digital display on an electronic clock to be speedily and readily corrected by speeding up the turning of the operation member to generate a pulse of adding or subtracting corresponding to the turning direction through a traveling contact.
CONSTITUTION: When the turning of a crown is speeded up by a wheel train and transmitted to a selective contact points, pulses having frequencies inversely proportional to the turning speed of the selective contact points are generated from pulse generating circuits 12W14 corresponding to fixed contacts S1WS3 which connect to the traveling contact. When these pulses are applied to a direction detector 15 comprising FF16WFF18 and the like, the detector 15 generates a gate controlling pulse corresponding to the turning direction of the traveling contact to control correcting signal gate groups 26 and 27. Thus, a pulse train X or Y corresponding to the turning direction of the selective contact points is generated from the groups 26 or 27. Said constitution permits the digital display on an electronic clock to be speedily and readily corrected according to the turning of the crown.
