Optical scanning apparatus wherein image scanning clock signal frequency is corrected to render scanning speed constant |
摘要 |
The speed at which a desired surface is scanned by a light beam is rendered constant by correcting the frequency of an image scanning clock signal without using an f lens. The characteristics of correcting the image scanning clock frequency can be varied, or the image scanning clock signal can be brought into phase with a recording position signal.
