ABSTRACT:
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.
