PROBLEM TO BE SOLVED: To provide a clock motor control device clock capable of returning the direction of the rotor to the original direction even when the rotor rotates in a forward rotation direction due to an impact. A clock motor control device has a rotor that rotates in a forward rotation direction that rotates a pointer clockwise or a reverse rotation direction that is opposite to the forward rotation direction, and a magnetic flux for rotating the rotor. It is a motor control device for controlling a stepping motor including a coil for generating a motor. The motor control device has a rotation direction determination unit that determines the direction in which the rotor is rotated by the impact based on the induced voltage generated in the coil, and the direction in which the rotor is rotated by the impact is the normal rotation direction. If determined, the coil is provided with a correction unit that applies a reverse drive pulse for rotating the rotor in the reverse direction. [Selection diagram] Fig. 1
