摘要： In a fixing unit, a fixing roller is rotated under driving force transmitted from a paper discharge unit-side gear of a driving section via a fixing roller driving gear, and holds and conveys a recording medium in cooperation with a pressure roller in a nip region. When a control section determines that acceleration conditions are fulfilled, the driving section increases the rotating speed of the paper discharge unit-side gear so that it is rotated at higher speed than before-acceleration speed over predetermined high-speed rotating period.

摘要： A manual sheet feeding mechanism adapted for use in a sheet processing apparatus includes a manual feeding tray and a guiding member. The manual feeding tray is adapted to be mounted on a side wall of the apparatus so as to be pivotable about an axis between an open position and a closed position. The manual feeding tray has a placement surface for placing a sheet to be manually fed into the apparatus. The guiding member is adapted to position a sheet placed on the placement surface and is provided so as to be movable on the placement surface. The manual sheet feeding mechanism also includes a moving member that is adapted, when the manual feeding tray is pivoted toward the closed position, to move the guiding member on the placement surface.

摘要： A feeding device according to the present invention holds a pile of sheets of paper in it. Feed force so acts selectively on a specified region of the upper side of the held top sheet as to feed the held sheets one after one in a feed direction. The feeding device includes a flat press plate and a support. The press plate is not smaller in the feed direction and the cross directions perpendicular to the feed direction than the maximum size of the sheets which can be held in the main body. The press plate is not larger in the feed and cross directions than the inner size of the main body. The press plate has a first opening formed over the specified region. The press plate is supported vertically movably above the held sheets by the support.
