  • Patent number: 10730710
    Abstract: In a paper cassette, a guide slides on a tray to place a sheet at a proper position. A lift mechanism uses a restoring force of an elastic member to push up the tray and make the sheet on the tray approach a pickup roller. When the paper cassette is pushed by a user from an opened position, which is out of the housing of a printer, to a closed position, which is in the housing, an adjuster mechanism mechanically converts a force of the user pushing the paper cassette to the restoring force of the elastic member from a time the guide reaches a specific point on a trajectory along which the guide travels together with the paper cassette, thus adjusting the strength of the restoring force continuously to a distance by which the guide overruns the specific point.

    Abstract: A sheet feed cassette includes a cassette main body, a sheet loading plate, a regulating member, and an auxiliary member. The sheet loading plate has a support surface and an opening. The support surface supports a sheet sheaf of one or more sheets. The regulating member is slidable within the opening in a sheet width direction perpendicular to a sheet feed direction. The regulating member regulates the sheet sheaf by coming into contact with an edge of the sheaf. The auxiliary member is supported by the sheet loading plate. The auxiliary member is in contact with the regulating member. The auxiliary member is turnable in parallel to the support surface in accompaniment to sliding of the regulating member. The auxiliary member supports a part of the sheet sheaf located over the opening.

  • Patent number: 9376279
    Abstract: A sheet feeding device includes a manual bypass tray, a pair of side-fences and restricting members. On the manual bypass tray, a sheet conveyed to an apparatus main body is placed. The pair of side-fences are arranged slidable in a width direction orthogonal to a conveying direction of the sheet so as to mutually approach/separate on the manual bypass tray. The restricting members are arranged attachable to/detachable from the pair of side-fences. Each of the restricting members includes a first engaging part and a preventive portion. The first engaging part is engaged with the manual bypass tray to restrict slide of each of the pair of side-fence in the width direction. The preventive portion is arranged so as to be separated upwardly from the manual bypass tray to prevent the sheet on the manual bypass tray from uplifting.
