Abstract
An optical part assembly includes a mirror main body including a base having a mirror support section that is formed integral with the base and a projected tip, a mirror mounted on the projected tip, a casing that has an opening in which to expose the mirror support section at a tip thereof, that has a rear end closed with a bottom plate, and that accommodates the mirror main body, a plurality of driving sections that are disposed on the bottom plate of the casing and act on the base to swing the base, a ring member having an opening and fixed to a front end part of the casing, a magnetic fluid that is disposed between the mirror support section and the ring member, and a plurality of springs that make contact with a front end part of the base and that elastically support the mirror main body.
Claims6
An optical part assembly comprising:
- a mirror main body including a base and a cylindrical mirror support section that is formed integral with the base and having a projected tip;
- a mirror mounted on the projected tip of the cylindrical mirror support section;
- a casing that has an opening in which to expose the cylindrical mirror support section at a tip thereof, that has a rear end closed with a bottom plate, and that accommodates the mirror main body;
- a plurality of driving sections that are disposed on the bottom plate of the casing and act on the base to swing the base;
- a ring member having an opening and fixed to a front end part of the casing;
- a holding member fixed to an inner circumference of the casing;
- a plurality of elastic members disposed between the base of the mirror main body and the holding member;
- and
- a magnetic fluid that is disposed between an outer peripheral surface of the cylindrical mirror support section of the mirror main body and the ring member to fill the opening of the ring member.
