Multimirror and transmission type projector using said mirror

Abstract

Abstract PURPOSE:To make the depth of a transmission type projector smaller by arranging plural belt-like mirror faces provided at some angle to a mirror base plate. CONSTITUTION:An image projector 1', multimirrors 2' and 3' and a screen 4' are disposed. The light emitted from the projector 1' is reflected by the mirrors 2' and 3' and is made incident to the screen 4' with the center of the reflected light directed in the direction toward the normal of the center of the screen. Said light is emitted from the screen 4' and the video thereof is viewed by the observer. The mirrors 2' and 3' are installed with an inclination to a front face 5' and a rear face 6' and it is also possible to install the same in parallel with the front face or the rear face by adjusting the sizes or positional relations of the projector 1', the mirrors 2' and 3' and the screen.
