Abstract

A projector includes a projection engine section including a light source section, an image forming section for displaying an image of a desired size on an irradiated surface using light from the light source section, and projecting light corresponding to an image signal to the irradiated surface, and a housing for housing the projection engine section, wherein the projection engine section is capable of moving in the housing in a direction along a light path.

Claims

1. A projector comprising:

a projection engine section including a light source section and an image forming section for projecting an image on an irradiated surface using light from the light source section; and

a housing for housing the projection engine section,

wherein the projection engine section is capable of moving in the housing in a direction along a light path.

2. The projector according to claim 1,

wherein the image forming section includes an angle widening reflection section for making light wide-angle by reflection.

3. The projector according to claim 2,

wherein the image forming section includes a projection lens, and

the angle widening reflection section makes the light from the projection lens wide-angle.

4. The projector according to claim 3,

wherein the projection lens and the angle widening reflection section are disposed so as to have substantially identical optical axes, and shift the light to a specific side from the optical axes.

5. The projector according to claim 1,

wherein the projection engine section is configured so as to allow a focus adjustment.

6. The projector according to claim 5,

wherein the image forming section includes a projection lens having a plurality of optical elements, and an angle widening reflection section for making the light from the projection lens wide-angle, and

at least one of the optical elements forming the projection lens is movable in an optical axis direction.

7. The projector according to claim 6,

wherein at least one of the optical elements disposed closer to the angle widening reflection section is movable.

8. The projector according to claim 5,

wherein the image forming section includes a plurality of mirrors, and at least one of the mirrors is movable.

9. The projector according to claim 3,

wherein the image forming section includes a spatial light modulation device for modulating the light from the light source in accordance with the image signal.

10. The projector according to claim 1,

wherein the light source section emits a laser beam, and

the image forming section includes a scanning section for scanning the laser beam from the light source, thereby displaying an image on the irradiated surface.
