  • Patent number: 7114716
    Abstract: A paper returner is placed in the vicinity of an end portion of a hopper for stacking a plurality of sheets of paper which faces a paper feeding roller, so as to be pivotable between a first position where the paper returner constitutes a part of the paper transporting passage, and a second position where the paper returner is isolated from the paper transporting passage. A separation pad is provided on a first face of the paper returner. The separation pad has a friction coefficient which is higher than a friction coefficient of the first face of the paper returner. The paper returner is placed at the first position so that a top sheet of paper in the hopper is abutted against the paper feeding roller, and is separated from other sheets of paper by the separation pad. The paper returner is placed at the second position so that the first face of the paper returner returns sheets of paper, which are entered in the paper transporting passage-together with the sheet of paper to be fed, to the hopper.

    Abstract: The feeding apparatus 50 includes a hopper 51 that is provided operable to support the papers in inclined attitude and pivot around a pivot axis 51a, and a feed roller 53 that is provided at a feed roller shaft 54 and feeds the paper to the downstream side by rotating in contact with the paper. When seen from the side view of the feeding path, guide rollers 57 and 58 are provided near the feed roller 53 and are driven to rotate in contact with paper. A movable member, provided near the feed roller 53, pivots around a pivot axis 63a so that the movable member moves backward and forward to the feeding path. Accordingly, a clearance between the feed roller 53 and the hopper 51 is narrowed.
