ABSTRACT:
A plurality of detection target portions are arranged around a rotating shaft of a rotating-body, one of which causes a detector to generate a first detection signal different from a second detection signal generated from the others. A first generating unit generates a reference signal indicating a reference rotational-position of the rotation-driving source or the rotating-body before one rotation from a timing of the first detection signal. A second generating unit reads periodic variation information from a storage unit based on the reference signal, and generates a rotation-velocity correction signal for the rotation-driving source.
