Image display element holding mechanism, prism unit, and projector
First Claim
1. An image display element holding mechanism for holding an image display element on a prism, comprising:
- a first fixing member that is fixed to a prism with an adhesive agent; and
a second fixing member that is fixed to the first fixing member with a screw, and to which an image display element is directly or indirectly fixed, whereina protrusion is formed around a hole that receives the screw,the first fixing member and the second fixing member contact each other directly or indirectly at the protrusion, andthe protrusion prevents distortion in an adhesion area of the first fixing member generated by tightening of the screw when fixing the first fixing member to the second fixing member after the first fixing member is fixed to the prism.

Abstract
A holding mechanism for holding an image display element to a prism includes: a first fixing member fixed to the prism by an adhesive; and a second fixing member, which is fixed to the first fixing member using a screw, and which has the image display element directly or indirectly fixed to the second fixing member. A protruding section is provided at the periphery of a hole to be used for the purpose of fixing using the screw, and at the time of fixing the second fixing member to the first fixing member using the screw, the first fixing member and the second fixing member are directly or indirectly brought into contact with each other at the protruding section such that deformation due to screwing of the screw does not generate within a bonding region of the first fixing member.

12. An image display element holding mechanism for holding an image display element on a prism, comprising:
-
a first fixing member that is fixed to the prism with an adhesive agent; and a second fixing member that is fixed to the first fixing member with a screw, and to which the image display element is directly or indirectly fixed, wherein the first fixing member includes a buffer portion that absorbs bending stress in an adhesion area of the first fixing member generated by tightening of the screw when fixing the second fixing member to the first fixing member after the first fixing member is fixed to the prism. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of manufacturing a prism unit, the method comprising:
-
fixing a prism on a first fixing member with an adhesive agent; and fixing, after fixing the prism on the first fixing member, a hole of a second fixing member that holds an image display element and a hole of the first fixing member with a screw, wherein the hole of the first fixing member is located outside of an adhesion surface of the first fixing member, a protrusion is formed around the hole of the first fixing member or the hole of the second fixing member, the first fixing member and the second fixing member contact each other directly or indirectly at the protrusion, the protrusion prevents distortion in an adhesion area of the first fixing member generated by tightening of the screw when fixing the first fixing member to the second fixing member after the first fixing member is fixed to the prism.
