ABSTRACT:
A position control device having first and second movable members. A first detector outputs a position signal when the first movable member is looked in a first predetermined position in a first region. A second detector outputs a first signal when the second movable member is located in either tbe first region or a second region where it is released, and a second signal when the second movable member is located in a third region. A controller determines the region in which the second movable member is located based on the detector outputs and when the determined region is the first region, an actuator moves the second movable member to a second predetermined position in the first region, and when the determined region is the second or third region, the actuator moves the second movable member to the second predetermined position.
