A control device is a control device (1) configured to be switched between open control and servo control and control a stepping motor (3), and includes a control unit (11) configured to reduce a switching frequency to the servo control, to be switched to open control after being switched to servo control to stop a mover at a target position and determine a current supplied to the stepping motor (3) in the open control based on a current command value when the mover is stopped at the target position in the servo control when a deviation between a position of the mover and the target position is a predetermined threshold or more when control of stopping the mover of the stepping motor (3) at the target position through the open control is performed.
