ABSTRACT:
A control device is provided for a stepping motor which connects with a drive system comprising a somewhat resilient member exerting a rebound force, such as a gear for the platen or a wire for the carriage in an electronic typewriter. When the stepping motor stops rotating in a determined direction, the control device rotates the stepping motor in the opposite direction for a minimum step to compensate for the unnecessary reverse rotation of the stepping motor caused by the resiliency in the drive system. Therefore, a transmission shaft of the stepping motor is freed from such an undesired external force as the resiliency of other parts and the stepping motor is always stopped in a position appropriate for a subsequent rotation.
