ABSTRACT:
An image processing apparatus furnished with an overhead projector has an image projecting function and an image-forming function. The image processing apparatus is designed to detect the movement of an original support table or a reflection-type focusing plate during projecting of an original. The result is that the original support table is free from being heated by the focusing plate and also that the focusing plate is free from any deviation of its axis of light, thus preventing the reflected light from striking on the eyes of the operator.
