ABSTRACT:
A projecting apparatus has a fixed mirror and two rotary mirrors whose rotary axes cross each other at a right angle are disposed on the projection side of a slide projector. An image is moved on a screen by controlling the angle of rotation of each of the rotary mirrors. With this arrangement, it is possible to impart motion to the image without need to perform projection while switching the slide projectors or to move the slide projectors themselves.
