摘要： An exposure-scanning apparatus in which an erect, equal-sized light image of an original document is focused on an image-receiving sheet. The apparatus comprises a transparent platen maintained stationary to support the original document. A scanning box is arranged to advance and then to return between first and second positions in parallel to the platen. An optical-exposure unit is arranged to move together with the scanning box. As the scanning box advances, the image-receiving sheet is advanced by means of a sheet-transport device in a direction the same as that of the scanning box at a speed twice that of the advance of the scanning box. A pair of push rollers are rotatably supported on the scanning box to push the image-receiving sheet onto the sheet-transport device at positions immediately before and after the light-image forming region in a direction of advance of the scanning box. The image-receiving sheet may be a photosensitive paper having a photoconductive surface.

摘要： Disclosed is an improved electrophotographic copying machine in which a black frame eliminating mechanism and a random cutting assembly adapted to cut a roll of photosensitive paper to a required length are incorporated. The black frame eliminating mechanism comprises an original supporting window, the length of which is longer than that of an original, an original depressing plate having a white surface facing and covering over the supporting window, means for depositing a charge over the length of a portion of a photosensitive paper, which length corresponds to that of the original, and means for exposing the paper placed at a predetermined position to the light from the entire area of the supporting window. The cutting assembly comprises first, second and third feed rollers arranged in this order along a paper feed passage, first means for driving the first and second feed rollers so as to feed the paper at a first synchronous feeding speed and second means for driving the third feed rollers so as to feed the paper at second feeding speed which is lower than the first speed, a one-way clutch adapted to allow the second rollers to feed the paper only in a downstream direction and cutting means adapted to cut the paper portion between the first and second rollers, wherein cutting of the paper is effected at the location between the first and second rollers when the drive of the first and second rollers is stopped, feeding of the paper is stopped at a position at the first rollers or upstream thereof, and slack of the paper portion between the second and third rollers, caused by difference between the first and second feeding speeds, is being changed to a tensioned condition.
