Abstract

A projector includes a projector body that enlarges and projects image light and an image reproducing device that reproduces an image relating to the image light. The projector body and the image reproducing device are integrally arranged in a vertical direction such that the projector body is above the image reproducing device. A partition member is formed between the projector body and the image reproducing device, and the projector body is placed on the partition member.

Claims

1. A projector, comprising:

a projector body including,

a light source,

a color-separating optical system that separates a light beam emitted from the light source into a plurality of color light components,

a plurality of optical modulators that modulate the separated color light components according to image information,

a color-combining optical device that combines the beams modulated by the plurality of optical modulators, and

a projection optical device that enlarges and projects image light combined by the color-combining optical device; and

an image reproducing device that reproduces an image relating to the image light,

the projector body and the image reproducing device being integrally arranged in a vertical direction such that the projector body is above the image reproducing device; and

a partition member between the projector body and the image reproducing device, the projector body being placed on the partition member.

2. The projector according to claim 1,

the partition member being integrally formed with at least one of a part of or all of a duct in the projector body and the image reproducing device.

3. The projector according to claim 1,

the partition member being formed with an introducing port that introduces heat from the image reproducing device.

4. The projector according to claim 3,

a heat generating portion in the image reproducing device being disposed right below or around the introducing port, and

a portion of the partition member facing the projector body being provided with a duct that communicates with the introducing port by air flow.

5. The projector according to claim 1,

the partition member being integrally formed with a lateral side that surrounds the projector body, and

the lateral side being formed with a peripheral rib that surrounds a front end of the projection optical device.

6. The projector according to claim 1,

an exhaust unit of the projector body and an exhaust unit of the image reproducing device being arranged adjacent to each other.

7. The projector according to claim 1,

the image reproducing device being a digital versatile disc (DVD) player.
