Abstract

A projector suspension device including a projection optical device having a reflecting mirror, and a suspension position adjustment mechanism, the suspension position adjustment mechanism includes: a pressing member which presses a first member and a second member; a screw member which, being fixed in the first member, passes through the second member; and a turning member which, by turning and engaging with the screw member passing through the second member, against the pressing force of the pressing member, adjusts the angle formed by the first member and second member, with a turning pivot set perpendicular to the axial direction of the screw member as the center.

Claims

1. A projector suspension device including a projection optical device having a reflecting mirror and a suspension position adjustment mechanism, comprising:

the suspension position adjustment mechanism includes;

a pressing member which presses a first member and a second member;

a screw member which, being fixed in the first member, passes through the second member; and

a turning member which, by turning and engaging with the screw member passing through the second member, against the pressing force of the pressing member, adjusts the angle formed by the first member and second member, with a turning pivot set perpendicular to the axial direction of the screw member as the center.

2. The projector suspension device according to claim 1, wherein

the screw member is disposed inserted through the pressing member.

3. The projector suspension device according to claim 2, wherein

the pressing member is formed of a coil spring.
