Abstract

A protector includes a projector body which has an image display unit which displays an image, a member to be projected onto which an image emitted from the image display unit is to be projected, and a connecting part capable of holding the member to be projected and the projector body at a predetermined distance therebetween and capable of accommodating the member to be projected within the projector body. The member to be projected can be unfolded in an in-plane direction.

Claims

1. A projector comprising:

a projector body which has an image display unit which displays an image;

a member to be projected onto which an image emitted from the image display unit is to be projected; and

a connecting part capable of holding the merger to be projected and the projector body at a predetermined distance therebetween and capable of accommodating the member to be projected within the projector body,

wherein the member to be projected can be unfolded in an in-plane direction.

2. The projector according to claim 1, further comprising a detector which detects the size of the member to be projected.

3. The projector according to claim 2, further comprising an image adjustor which adjusts the size of the image emitted from the image display unit according to the size of the member to be projected, which is detected by the detector.

4. The projector according to claim 2, further comprising an illuminance adjustor which adjusts the illuminance of the image emitted from the image display unit according to the size of the member to be projected, which is detected by the detector.

5. The projector according to claim 1,

wherein the member to be projected is provided with a heat radiating section which radiates heat in the heat generated in the projector body.

6. The projector according to claim 5,

wherein a refrigerant flow passage through which a refrigerant can be circulated is formed inside the connecting part, and the refrigerant flow passage is connected with the heat radiating section.

7. The projector according to claim 6,

wherein the refrigerant is a liquid, and the liquid carries the heat generated in the projector body to the heat radiating section.

8. The projector according to claim 6,

wherein a heat pipe which carries the heat generated in the protector body to the heat radiating section is provided within the refrigerant flow passage.
