PURPOSE:To display sufficient compensation effect of a load by using different sampled pulses for a driver circuit, driven by different driving pulses in stationary operation and abnormal operation, in stationary operation and in abnormal operation respectively. CONSTITUTION:A crystal clock circuit consists of crystal oscillator 107, divider circuit 108, waveform converter circuit 109, driver circuit 110, counter 111, phase shifter circuit 112, sample pulse generator circuit 113, detector circuit 114 and pulse motor 115. This sample pulse generator circuit 113 generates different sample pulses in stationary operation and abnormal operation. Further these sample pulses are so made that they are different each other in phase in stationary operation and abnormal operation. Therefore, it stops detector circuit 114 form changing pulses into stationary driving pulses in earlier stage due to error decision of detector circuit 114 and outputs continuously prescribed high outputs, thereby displaying sufficient compensation effect of a load. |
