PROBLEM TO BE SOLVED: To enable abnormal driving of a movable member to be determined at desired timing in a case of driving the movable member to move on a predetermined path.SOLUTION: A driving device includes: a motor that drives a movable member to move on a predetermined path; and a sensor that detects movement of the movable member. The motor is controlled to drive the movable member for predetermined time at predetermined power (S11). During driving, it is determined whether the sensor detects the movement of the movable member in a direction of the driving by a length equal to or larger than a predetermined length (S12, S13). If it is determined that the movable member does not move by the length equal to or larger than the predetermined length, it is determined that abnormality occurs. |
