Abstract:
1. A light scanning unit for scanning light on an exposed surface of a photosensitive medium, comprising: a light source to generate and illuminate at least one beam that corresponds to an image signal while being controlled on and off; a beam deflector to deflect and scan a beam provided from the light source; and a reflection mirror obliquely arranged so that a segment formed by a projection plane of the reflection mirror onto the exposed surface is maintained inclined with respect to a segment perpendicular to a transferring direction of the exposed surface to direct the scanning line to the exposed surface of the photosensitive medium by reflecting the scanning line provided from the beam deflector, the reflection mirror being arranged such that an optical path between the light source and a scan starting point on the reflection mirror is shorter than an optical path between the light source and a scan ending point on the reflection mirror.
