Abstract

PURPOSE:To realize not only a small-sized structure but a simple adjustment mechanism of a laser recorder, by providing an optical member which is capable of adjustment and of preserving the state after an adjustment between an f-theta lens and a photoreceptor layer. CONSTITUTION:A housing 10 made of an aluminum casting, etc. contains a laser tube 2, a modulated optical element 3, a beam expander 4, rotary polyhedric mirror 5 which is driven by a synchronous motor 5a, and an f-theta lens that focuses the laser beams given from the mirror 5a and irradiates the laser beams on the surface of a photoreceptor drum 7 in the form of a spot light which shifts in the same speed from one to another side. The laser beam reflected by a fixed mirror 20 is led to the drum 7 through an adjustment mirror 30. The mirror 30 is made movable by means of three control female screw members. As a result, the shift of position can be adjusted for the length of an optical path reaching the drum 7 from the f-theta lens, the main scanning direction or the subscanning direction.
