ABSTRACT:
The apparatus comprises a projection optical system and a copying system. The projection optical system can project an image of an original either onto a screen or to an exposing position of the copying system by switching between two positions. The copying system comprises a plurality of chargers providing different charging conditions in accordance with the types and sizes of copy sheets, by utilizing a change-over switch. A plurality of switches adapted for use with copy sheets of different lengths are arranged along the path of movement of a sheet of paper and, when the switch corresponding to the particular length of copy sheet desired is actuated, the movement of the sheet of paper is stopped, so that the central portion of the copy sheet can be brought into alignment with the optical axis for exposing at all times regardless of the difference in the length of copy sheets. Apparatus can interchangeably mount either a pressing plate assembly for manually feeding one original after another or an automatic feed device which can automatically feed one by one a plurality of originals to the exposing position of the copying system and to eject the same therefrom. By switching between the charging conditions of the chargers, it is possible to produce a positive duplicate of an original irrespective of whether the original is negative or positive. The pressing plate assembly and automatic feed device comprise carriers for effecting moving in X-and Y-directions which are interchangeable, so that it is possible to select a carrier which best suits the size of an original and the amount of movement of the original. The projection optical system comprises a blind coupled to a reflector so as to prevent light from the screen from reaching the exposing position of the copying system, the reflecting surface automatically facing downwardly when the power source is turned off.
