摘要： PROBLEM TO BE SOLVED: To prevent noise emission at the convergence part for transporting sheets fed via a plurality of guide paths to the specified destination, wherein the noise originates from a rebound of the trailing edge of sheet caused by a step formed by other guide path. SOLUTION: A sheet fed by a hand feed part or a feeder part is sent to a resist roller 20 installed in the convergence part 35, where two curved paths converge, i.e., a second curved path to guide the sheet fed by the hand feed part to convergence part 35 and a first curved path to guide the sheet fed by the feeder part to the convergence part 35, and in this position a movable guide 40 is installed. The movable guide 40 is maintained in such a condition as not blocking the two curved guide paths and put in rotational control in accordance with the passage of the trailing edge of the sheet fed from the hand feed part so as to eliminate a step formed by the first curved path, and the second curved path 32 is coupled with a guide body 37 to form the convergence part 35 by the guide piece 40b of this movable guide 40, and thereby noise emission is precluded originating from a rebound of the trailing edge of sheet.

摘要： PURPOSE:To prevent an image receiving sheet, specially, its rear end part from being stained by pressing the pressure rollers when the front end of a latent image reaches the position of the pressure roller and releasing the rollers from being pressed when the rear end of the latent image passes the position of the pressure rollers. CONSTITUTION:A buffer roller 3 is moved as shown by an arrow A to draw a photosensitive sheet 2 out of the supply shaft 1a of a cartridge and the sheet is exposed at an exposure part P1 to reflected light from an original 4a to form the latent image on the sheet 2. When the exposure is finished, the roller 3 is moved as shown by an arrow B to feed the sheet 2 to a pressure development part P2 and the sheet is superposed upon the image receiving sheet 8 and pressed between pressure rollers 6a and 6b to perform pressure development processing. When the latent image front end of the sheet 2 reaches the development part P2, the sheet is pressed while the rollers 6a and 6b are rotated and when the latent image tail end reaches the development part P2, the sheet is released from being pressed to prevent dye from sticking on the rear end part of the sheet 8.

摘要： PURPOSE:To impart sufficinet heat quantity even if an image receiving sheet made of an OHP film is used and to prevent the occurrence of a void by slowing down an image forming process at the time of thermal processing when the image receiving sheet is discriminated to be an OHP film. CONSTITUTION:A sensor S1 detects the amount of light transmitted by the image receiving sheet 7 carried from a paper cassette to discriminate the type of the image receiving sheet 7. If the supporter of the image receiving sheet 7 is plain paper, the light transmitting amount is less, whereas if the supporter is OHP film, the light transmitting amount is greater. Therefore, the light quan tity is detected to discriminate the type of the image receiving sheet. If the supporter of the image receiving sheet 7 is OHP film, the image forming process is slowed down and thermal processing is also slowed down. Consequently, sufficient heat quantity is imparted to the OHP film, thereby obtaining a void- free, glossy image.

摘要： PROBLEM TO BE SOLVED: To surely prevent the jamming of an original on an original reading position when the original is carried while an upper surface on an original platen is not perfectly closed by an original cover by detecting the open/close state of the upper surface of the original platen by the original cover and deciding whether or not original moving mode is performed. SOLUTION: Light radiated from an exposing lamp 23 is reflected by an original cover plate 10 on the original reading position in the original moving mode, and the reflected light is read by a CCD 26 (photoelectric conversion element). Since the level of the reflected light is changed in accordance with the open/close state and the surface condition of the plate 10, the open/close state of the original cover 4 can be detected by the comparison of a reference lever and a reflected light level. The surface condition such as the soiling of the plate 10, etc., can be grasped.
