摘要： A mirror surface for deflecting an incident light beam is inclined to the axis of rotation and rotated for scanning the light beam. The incident light beam is applied to the mirror surface along the axis of rotation, and a reflected light beam is continuously deflected by the rotating mirror surface to scan a surface. When the incident light beam has an elliptical cross section in a direction normal to its optical axis, the cross-sectional shape of the reflected light beam varies due to the inclination of the mirror surface in response to rotation of the mirror surface. The varying shape of the reflected light beam obstructs proper reading and writing of an image with a light scanning device employing the above mirror surface. To avoid this problem, light beam shapers are provided in positions before and after the light beam is reflected by the mirror surface.

摘要： A compact laser printer has an up-side down arrangement of components within a machine housing. That is, an optical writing unit is disposed below a rotatably supported photosensitive drum and an image transferring unit is disposed above the photosensitive drum with a developing unit disposed substantially in a side-by-side relationship with the photosensitive drum. A paper feed cassette is located below the optical writing unit when detachably set in position and a paper transportation path extends from the supply end of the paper feed cassette around the developing unit generally in the shape of "U." The machine housing has a pivotally movable portion which may be pivotted open and closed. The photosensitive drum and/or one of a pair of registration rollers may be mounted on the pivotally movable portion.

摘要： A ribbon feed mechanism for a printer which develops a drive force for a printing ribbon utilizing the reciprocating movement of a carriage. Torque is applied to two drive gears through a single wire under tension in response to the movement of the carriage. A ribbon drive gear for feeding the ribbon in a predetermined direction is alternately meshed with the two drive gears during reciprocation of the carriage to be thereby rotated in a predetermined single direction. When the ribbon feed is needless, the tension is removed from the wire.
