Abstract
A signal adjusting apparatus comprises a movable member, a first detecting device, a second detecting device, and a correction device. The member is movable in a movable range composed of a plurality of intervals. The first detecting device detects one of the intervals where the member is located. The first detecting device is constituted by a first movable portion mounted on the member and a first fixed portion spaced apart from the first movable portion. The one of the intervals is an absolute position. The second detecting device detects a relative position of the member within the detected interval. The second detecting device is constituted by a second movable portion mounted on the member and a second fixed portion spaced apart from the second movable portion. The correction device corrects the detected relative position based on a relationship between the absolute position and the relative position stored in a memory.
