摘要： In a light deflecting device using a polygon mirror, a polygon mirror member is provided which has a reference surface and a plurality of integral mirrored surfaces formed at a predetermined angle with respect to the reference surface. A fixing member resiliently fixes the polygon mirror member to a drive shaft for rotatively driving the polygon mirror member. The fixing member is effective to vary the angle formed between the reference surface and the drive shaft. A plurality of float members are provided in opposed relationship with the reference surface of the polygon mirror member and fixed independently of the rotation of the polygon mirror member. The float members are effective to produce a flow of air between the reference surface and the float members during rotation of the polygon mirror member to maintain a predetermined distance therebetween.

摘要： A scanning device for light beams, wherein, for the purpose of permitting positional displacement of a scanning light beam to a certain extent in the direction perpendicular to its scanning direction, which is possibly caused by tilting or inclination of the reflection surfaces of scanning means such as a polygonal mirror, there is disposed a tolerating optical system in the light path of the light beam from the above-mentioned reflection surfaces. The positioned displacement of this light beam caused by tilting of the reflection surfaces of the light beam scanning means can be tolerated by a positional displacement tolerating optical system, wherein the focal length in the direction perpendicular to the scanning direction of the light beam is shortened in comparison with the focal length in the scanning direction of this tolerating optical system.

摘要： A prism anamorphic optical system is disposed in the path of deflected beam from a rotatable polygonal mirror or a galvano-mirror. This prism anamorphic optical system includes at least two prisms, so that different amounts of displacement of the deflected beam at each angle of deflection and in a direction perpendicular to the direction of deflection caused by the first of the prisms are corrected by the second and subsequent prisms, as viewed from the incidence side. Thus, a straight scanning line may be obtained.
