PURPOSE:To stop the minute hand always in the position of a just minute at the fast feed correction by providing a counter which counts driving signals to an electronic timepiece provided with an two hand type analog display part. CONSTITUTION:When a push switch 22 is turned on and off once, a gate 15 is put in the state of passing, through which a 64Hz signal is inputted to an output circuit 14, and a motor is fast fed. At the same time, this fast feed signal is inputted to a hexad counter 21 and when the minute hand is fast fed to a just minute position, a carry signal is outputted therefrom. An RS flip-flop 20 is reset by this carry signal, by which the gate 15 is closed to stop the fast feed signal. When the push switch 22 is pushed for >=2 seconds, the minute hand is fast fed similarly, but the RS flip-flop 18 is preferential to be set and therefore the carry is disregarded and the minute hand is fast fed until the first carry signal, after the switch 22 is turned off, is generated. |
