Abstract

PURPOSE: To make it possible to make a time correction in a short time by eliminating the need of a mechanical part, by adding electromagnetic reversible correction function to a pulse motor driving hand-handling display.
CONSTITUTION: The driver curcuit for a step motor applied with voltages from battery 5 and boosting circuit 6 consists of OUT1 buffer 31 and OUT2 buffer 32. To reverse the motor rapidly, reverse rapid turn switch 37 is turned ON with positive rapid turn switch 36 OFF to pass a rapid turn signal through AND gate 13, where it changes into an OUT1 driving signal. Then, a reverse driving signal starting from the same polarity as the final positive driving signal is supplied to the pulse motor and a reverse driving signal of higher voltage than that of the positive driving signal is also supplied.
