Abstract

In order for a tip end portion of a holding plate not to catch up on a cover glass holder when a lamp unit is stored in a lamp storage unit, a surface of the cover glass holder which confronts the holding plate is processed into a shape which does not project, in concrete terms, into the shape of a curved surface or the shape of a sloping plane. By doing this, even though the tip end portion of the holding plate strikes against the cover glass holder, since it passes smoothly thereover without catching up thereupon, accordingly, it is possible for the lamp unit to be smoothly stored in the lamp storage unit.

Claims

1. A projector, comprising: a lamp storage unit to which a lamp unit which emits light for projecting a picture towards a screen can be freely fitted and removed, and which stores this lamp unit in a state of being tilted at a fixed angle; anda holding plate, a tip end portion of which extends out in the direction in which said lamp unit is removed, and which contacts against a cover glass holder which fixes a cover glass provided to a light beam projection aperture formed in a front surface of said lamp unit, thus holding said lamp unit;wherein a surface of said cover glass holder which, when said lamp unit is fitted, faces said tip end portion of said holding plate, is processed into the shape of a curved surface which is convex towards the side of said holding plate.

2. A projector, comprising: a lamp storage unit to which a lamp unit which emits light for projecting a picture towards a screen can be freely fitted and removed, and which stores this lamp unit in a state of being tilted at a fixed angle; anda holding plate, a tip end portion of which extends out in the direction in which said lamp unit is removed, and which contacts against a cover glass holder which fixes a cover glass provided to a light beam projection aperture formed in a front surface of said lamp unit, thus holding said lamp unit;wherein a surface of said cover glass holder which, when said lamp unit is fitted, faces said tip end portion of said holding plate, is processed into the shape of a sloping plane which is sloped towards the side of said lamp unit.

3. A projector as described in claim 1, wherein the vicinity of the end of said holding plate is processed by bending into the shape of a curved surface.

4. A projector as described in claim 2, wherein the vicinity of the end of said holding plate is processed by bending into the shape of a curved surface.
