Abstract
An overhead projector has a flat stage, for placing a sheet material thereon, which is inclined such that a normal line of the flat stage, which is in alignment with the optical axis of the projection lens, inclines an angle relative to a vertical line so that a reflection mirror disposed above the projection lens at an angle of 45 degrees directs an image projected by the projection lens toward a remote screen at a desired angle of elevation.
