DRIVING CIRCUIT FOR STEPPING MOTOR

摘要

PURPOSE:To drive forward and reverse revolution stably by simple constitution by providing an inversion processing circuit which holds at least one pulse section in driving pulses and addes it to a pulse distributing circuit when forward and reverse signals are inverted. CONSTITUTION:The inversion processing circuit 6 is set up among both a pulse generator 4 and a forward and reverse command circuit 5 and the pulse distributing circuit 3. The inversion processing circuit 6 fixes pulses from the pulse generator 4 at a ''1'' or ''0'' level for a fixed time when forward and reverse signals are inverted to ''1'' from ''0'' or ''0'' from ''1'' and the direction of revolution of the stepping motor 1 is inverted, and has the same function as the stepping motor 1 is stopped for a fixed time.
