Abstract
An electrode-optical device mounting unit for a projector is disclosed. The mounting unit includes a panel frame body holding liquid-crystal-panels and having a plurality of holes provided in the periphery thereof, and fixing pins each having a flat part formed at one end surface thereof and a deformed part formed at an end on the side different from the side on which the flat part is formed. The fixing pins are inserted into the holes, wherein a light-incident surface of a prism composition and the flat part of each of the fixing pins are fixed by an adhesive agent, and the inside of the holes of the panel frame body and an outer peripheral surface of each of the fixing pins are fixed by an adhesive agent.
Claims19
A projector, comprising:
- an electro-optical device that modulates light;
- a prism to which the electro-optical device is mounted;
- a projection lens that projects the modulated light;
- an electro-optical device frame body that holds the electro-optical device and has a plurality of holes provided in a periphery thereof;
- and
- fixing pins each having a flat part on one end surface thereof, the fixing pins being inserted into the holes of the electro-optical device frame body, a light-incident surface of the prism having peripheral edges and a flat part of each of the fixing pins being fixed by an adhesive agent, and an inner portion of the holes and an outer peripheral surface of each of the fixing pins being fixed by an adhesive agent.
An electro-optical device-mounting unit that mounts an electro-optical device that modulates light to a prism, comprising:
- an electro-optical device frame body for holding the electro-optical device and having a plurality of holes provided in the periphery thereof;
- and
