Claim Text:
1. A projector comprising: a body including a light source, a display plane illuminated with light from the light source, and a projection optical system that projects light from the display plane; and a projection unit that projects the light from the display plane through the projection optical system toward an illumination-targeted plane, the projection unit having a negative power convex angle-widening mirror, the angle-widening mirror reflecting light forming an image plane of the display plane for angle-widening, and the image plane being inclined to the display plane, wherein the body is detachable from the projector, and the projection optical system is switchable between a normal display state where an image forming the image plane of the display plane, the image plane being parallel to the display plane, is formed in a first range of a relatively long distance along an optical axis and a macro display state where an image forming the image plane of the display plane, the image plane being parallel to the display plane, is formed in a second range of a relatively short distance along the optical axis.
