Verfahren und Vorrichtung zur Steuerung eines rotierenden Körpers, Prozesskartusche, Bilderzeugungsvorrichtung und Computerprogrammprodukt

摘要

A plurality of detection target portions (33,34,35,36) are arranged around a rotating shaft (1A) of a rotating-body (1), one of which (33) causes a detector (37) 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 (1) 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.
