  • Patent number: 4056320
    Abstract: The copying machine permits a selective use of either a single sheet original, or a file original such as a book, and in which an original is moved by means of rollers for scanning an image thereof. A plurality of drive rollers are disposed on the under side of a path of movement of an original to be copied, whereas mating driven rollers are mounted on a movable frame so that they can be retracted from their normal position when a file original is used. The frame is manually moved to the retracted position without substantial change in its posture, thereby permitting an operator to easily operate the frame. After the frame is retracted, a file original may be placed on a transparent sheet member which is arranged to be fed on the drive roller so as to be moved thereby for scanning.

  • Patent number: 3947020
    Abstract: A device for separating a copy sheet and an original that are delivered together by copying apparatus along a common path, including suction means for drawing the original from the path and a curved guide plate for guiding the copy sheet as the original is separated therefrom. The suction means, disposed at one side of the common path, includes a curved suction surface and plural apertured endless belts passing over the surface in position for register of apertures of the belts with suction openings formed in the surface. The guide plate, disposed at the opposite side of the common path, has a sheet-engaging surface with a degree of curvature, relative to the last-mentioned path, that is less than the curvature of the suction surface but greater than a predetermined curling limit of the copy sheets being separated.
