PURPOSE:To largely reduce the power consumption by driving a pulse motor with a signal having short ON period. CONSTITUTION:The outputs B, C, D, E of a signal generator 1 for generating four pulse signals for driving a pulse motor become ON signals F, G, H, I becoming the prescribed short ON period corresponding to the rise of a monostable multivibrator 2, and OR of the signals is produced by an OR circuit 3. The AND of the signals F, G, H, I of the OR circuit 3 and the outputs B, C, D, E of the signal generator 1 is produced by AND circuits 41, 42, 43, 44 to generate J, K, L, M signals. These signals are supplied to the pulse motor M, and the current having the prescribed short period is flowed. |
