Abstract
PURPOSE: To prevent the occurrence of uneven transfer by providing such a feed mechanism that an electrostatic latent image holding medium is kept still at the time of exposure in an exposure part and yet the electrostatic latent image holding medium is fed at a constant speed on other portion.
CONSTITUTION: When the film between a brake roller 12 and a roller 16 stops and even while exposure is being accomplished by an exposure device 18, the film 11 is kept constantly fed by a feed roller 13 and therefore tension rollers 14 and 15 have been moved to the position shown by the dotted line in the figure. Upon ending of exposure, a photosensitive plate 22 and the film 11 are separated and the brake of the brake roller 12 is released, then the tension rollers 14 and 15 return to the initial position at an arbitrary speed without hampering the feed of the film. At this time, the film 11 of the portion superposed on the photosensitive plate 22 is rapidly delivered out from the exposure part.
