Abstract

A projector for image projection, includes: an optical element included by an optical system to project an image; a tripod that supports the projector; and a tripod-fixing part that is connected with the optical element and fixes the tripod, wherein the tripod and tripod-fixing part are each constituted by a heat-conductive member.

Claims

1. A projector for image projection, comprising:

an optical element included by an optical system to project an image;

a tripod that supports the projector; and

a tripod-fixing part that is connected with the optical element and fixes the tripod,

wherein the tripod and tripod-fixing part are each constituted by a heat-conductive member.

2. The projector of claim 1, further comprising a part that constitutes a circuit to send and receive radio waves,

wherein the part constituting the circuit and the tripod-fixing part are provided in positions opposed to each other with the optical element located in a middle of a spacing therebetween.

3. The projector of claim 1, further comprising a part that constitutes a circuit to send and receive radio waves,

wherein the tripod is constituted by a heat-conductive and electrically conductive member,

the tripod-fixing part is constituted by a heat-conductive and electrically insulative member,

at least one leg of the tripod is connected to the part that constitutes the circuit through an electrically conductive connecting member.

4. The projector of claim 1, wherein the part constituting the circuit and the tripod-fixing part are provided in positions opposed to each other with the optical element located in a middle of a spacing therebetween.

5. The projector of claim 1, wherein the optical element connected with the tripod-fixing part is a light source that launches light for image projection.
