Abstract
PURPOSE: To reduce the number of circuit elements and to improve the operability by controlling the drive output of a step motor in accordance with the time elapse after the operations of external contacts with the use of a counter of a frequency divider.
CONSTITUTION: The output of an oscillator OSC is fed to a counter composed of FF 1 to 15, and the Q and antiQ outputs of the FF 15 are fed to a decimal counter composed of FF 16 to 18 and NOR gates G9 and G10. The Q outputs the FF 8, 11 and 16 to 19 are indicated at Q 8, 11 and 16 to 19, and the counter composed of the FF 11 to 19 is used as a counter for controlling the fast forward start and stop of the step motor and for dividing the frequency of the OSC. The measuring time of the counter M when the outside contacts for operations are conductive is used to determine the start time of the fast forward, the fast forward period, and the stop time of the same.
