Abstract
A projection copying apparatus having an image forming lens, a first reflection member opposed to the lens, a reader optical path lens system and a printer optical path lens system. The reader optical path lens system includes a movable reflection member, and projects an image onto a screen when the apparatus is in a reading mode. When the apparatus is in a printing mode, a driving device moves the printer optical path lens system in such a manner to reflect light from the first reflection member onto a photosensitive medium. The movable reflection member is moved in and out of a reflection light path of the first reflection member to change the apparatus between the reading mode and the printing mode.
