Claims21
A support for an elastic member of a lens in a laser printer, and the support comprising:
- a support member having a first surface and a first apertured portion;
- a support portion having a second apertured portion, said support portion extending beyond said first surface of said support member through said first apertured portion,
- a positioning unit disposed in said second apertured portion, said lens being disposed in said second apertured portion with said positioning unit wherein said support portion is formed of an elastic material, said support portion being adapted to elastically urge said lens against said positioning unit.
A support structure for supporting an elastic member, comprising:
- a fundamental portion having a basic side;
- and
- a support member made of elastic materials fixed to said fundamental portion, said support member supporting and positioning said elastic member on the basic side of said fundamental portion by utilizing the elasticity of the elastic materials.
An optical apparatus comprising:
- a fundamental portion having a basic side;
- an optical resin member supported on said fundamental portion and arranged in a light path;
- and
- a support member made of elastic materials including a support portion, said support portion supporting said optical resin member biased toward the basic side of said fundamental portion and fixing said optical resin member to said fundamental portion.
