PROBLEM TO BE SOLVED: To obtain a motor control circuit used for printer motor, in which incomplete rotation due to erroneous operation due to the noise of FG and abnormal heating due to the locking of motor are prevented. SOLUTION: A motor acceleration signal is outputted when a first set time of a timer circuit 70 operating in response to the rotational signal of a motor 50 is reached, and normal rotation is reset, when the motor 50 is unlocked by imparting rotational torque forcibly. When the motor 50 is locked continuously, a motor deceleration signal is delivered upon reaching a second set time, in order to protect the motor 50 and the output element against abnormal heating. |
