とするオーバーヘツドプロジエクター。[Claims for Utility Model Registration] An optical system having lenses, mirrors, prisms, and other optical members that irradiates light from a light source onto a substantially light-transmitting original placed on a document holder and uses the transmitted light that passes through the original. In an overhead projector that enlarges and projects images using a system, a liquid crystal display element has a liquid crystal shutter substrate in place of the original document in the optical path from the light source to the optical system, and a display image of the liquid crystal display element cooperates with the optical system. 1. An overhead projector characterized by being detachably provided with a liquid crystal display device having another optical system for forming an image and projecting an enlarged image.
