Abstract

PURPOSE: To make it possible to detect the rotating condition with the use of a simple electronic circuit, while facilitating the circuit intefration, by comparing the counted value of the intervals of the pulses which are generated in accordance with the rotations.
CONSTITUTION: Pulses are generated by means 12 in accordance with the rotations of a rotor 13 which is driven by a motor 3. The intevals of the pulses generated are counted by a counter 24 so that the counted value at present is compared and detected with the detection data which are preset in a chode generator 28. When the counted value exceeds the data, an FF 29 is set so that the stop is displayed in a display device 32 in accordance with the output and so that a drive circuit 31 is simultaneously controlled to stop the rotations of the motor 3.
