Projector
First Claim
1. A projector which projects an image by means of a projection light onto a surface approximately parallel, or a surface approximately perpendicular, to an installation surface, comprising:
- a first reflecting surface which reflects the projection light toward the approximately parallel surface;
a second reflecting surface which reflects the projection light toward the approximately perpendicular surface; and
a reflecting surface switching section which can switchably place the first reflecting surface and the second reflecting surface in an optical path of the projection light.

Abstract
An image by means of a projection light is projected without any distortion both onto a surface approximately parallel to an installation surface, and onto a surface approximately perpendicular to the installation surface.
In a case in which reflecting surfaces are held in a horizontal condition, and a reflecting surface of a reflecting mirror on which a projection light falls is formed into a planar surface, individual light rays fall on positions on a table surface. As these positions are evenly spaced, an image projected onto the table surface becomes a non-distorted image. On the other hand, in a case in which the surfaces are held in an inclined condition, and a surface on which the projection light falls is formed into a curved surface, individual light rays caused to emerge from a light modulation device at even intervals fall on a wall surface. Incidence positions of the individual light rays being evenly spaced, an image projected onto the wall surface becomes the non-distorted image.
