PROBLEM TO BE SOLVED: To provide an initialization driver in which the difference between the actual position of a driven member and the right position thereof can be reset surely. SOLUTION: An initialization means comprising an initialization rotating means, a contact detecting means and a rotation ending means performs initialization operation for resetting the difference between the actual position of a driven member and the right position thereof at a specified timing. A decision means makes a decision whether a drive voltage is equal to or higher than a predetermined threshold level or not. When the decision means makes a negative decision, an initialization stop means stops initialization operation by the initialization means. |
