Abstract
A single position-detecting means for detecting rotation positions of electric motors is provided. Positions of a plurality of driven members are detected (estimated) based on the detection results. When a request of simultaneously operating the plurality of driven members is made, by sequentially operating the plurality of driven members one by one, the rotation positions of the plurality of electric motors can be detected by the single position-detecting means.
