PURPOSE:To obtain an electrophotographic copying machine small in size and weight, and low in price, by moving a slit exposure light source without moving an original. CONSTITUTION:A film type original support 3 windably is held with a pair of rolls 1, 2, and it is transparent, and insulating on the face in contact with a photoreceptor 7. A film type photoreceptor 7 is windably held with a pair of rolls 4, 5. The support 3 and the photoreceptor 7 are held in close contact with each other, and a moving body 11 moves under the photoreceptor 7 moves at least in the range for exposing the backside of the photoreceptor 7 to the optical image of the original on the support 3, and it has an opening on the upside, and rolls 10 for rotating along the backside of the photoreceptor 7, ratchets 23 above the outsides of both side ends, and a light source 7 for exposing the photoreceptor 7 and a reflective mirror 21 in the inside. |
