Abstract
An overhead projector in which a light from a light source is transmitted through an original, and a resulting original image is projected on a screen by means of a projection optical system including a projection lens and a half-mirror. At the same time, the original image is transmitted through the half-mirror, and delivered to a record medium by means of an exposure optical system. The exposure optical system includes a shutter member which can be shifted between a shielding mode and a copying mode. In the shielding mode, the optical path of the exposure optical system is closed to permit projection on the screen. In the copying mode, the optical path is opened so that the original image, to which the record medium is exposed, is visualized on the record medium by a developing process. At the end of the copying mode, the record medium is discharged into a tray.
