Title:
DRIVE DEVICE FOR STEPPING MOTOR
Document Type and Number:
Japanese Patent JPS6126499
Kind Code:
A
Abstract:
PURPOSE:To effectively convert normal to reverse by using an A/D converter, a delay circuit, a flip-flop and a register to digitize it. CONSTITUTION:An input signal (a) is converted by a clock signal o by an A/D converter 13 into a digital signal (p). The clock signal o is delayed by a delay circuit 4 more than the converting time of the converter 13, and its output (g) is input to a T flip-flop 15. Whenever a pulse signal (g) is input to the flip-flop 15, the output of the converter 13 is alternately held at the first and second registers 16A, 16B, the outputs of the first and second registers are compared by a comparator 17, an exclusive OR gate 10 is controlled by the output to switch the pulse phase to an amplifier 11B to rotate normally or reversely a stepping motor 12.
