<p>PURPOSE:To obtain a copying picture with high resolution by press-contacting sandwiching and carrying partially a photosensitive material by a roller, in the rotating axis direction and providing a continuous guide member over the output side from the penetrating side of two pairs of rollers. CONSTITUTION:In an assembling condition, when the copying process is started, the tip part of a photosensitive sheet S is introduced along the inner surface of respective curved surfaces with an upper direction guide part 15C of a frame body 15 and an upper guide part 16C of a rear surface receiving plate 16, and sent to the position for press-contacting a driving conveying roller 10 and a driven conveying roller 11. At such a position, the photosensitive sheet S is press-contacted and sandwiched by conveying rollers 10 and 11, conveyed in the lower direction, and passes through the slit part to form the prescribed clearance faced by the frame body 15 and the rear surface plate 16. While the photosensitive sheet S passes through and shifts on a glass plate 14 of the slit part, the original picture scanned and exposed by the exposing device passes through a slit 21 from the fifth mirror 7 through the optical system and exposes the photosensitive surface by the prescribed width. Thus, the focus defect due to the non-smoothness of the conveyance, etc., is eliminated and the copying picture with a high resolution can be obtained.</p> |
