摘要： A line sensor that detects the edge position of a recording paper is provided on the upstream side of a transfer point where an image formed on a first photosensitive drum is transferred to the recording paper. When performing borderless image formation, the size of the image on the first photosensitive drum to be transferred to the midstream of the recording paper after detection of its edge position is changed to a smaller size based on the detection results by the line sensor, and subsequent image formation to the recording paper continues to be performed according to this image on the photosensitive drum whose size has been changed.

摘要： A shifting mechanism includes a guide plate, a bearing, a rotating shaft, a delivery roller, and a bearing unit. The shifting mechanism delivers a sheet of paper along a delivery passage and offsets the sheet horizontally and perpendicularly to the passage while delivering it. The guide plate has an opening forming part of the delivery passage and an end hole formed through the front end of the plate horizontally and perpendicularly to the passage. The rotating shaft extends through the end hole. The delivery roller is fixed to the rotating shaft. The sheet passes through the nip between the delivery roller and the guide plate. The bearing unit extends movably through the end hole and includes a sleeve, which supports the rotating shaft horizontally and perpendicularly to the delivery passage. The bearing unit rotates the rotating shaft.

摘要： A sheet feeding device includes a sheet support, a restricting portion, a displacement section, and a link section. The restricting portion slides along a line passing through restricting points. The restricting portion restricts the position of the sheet when the restricting portion is positioned at each of the restricting points. The link section interlinks the restricting portion and the displacement section. The position of the displacement section is detected. The link section, which interlinks the restricting section and the displacement section, is configured to change a ratio of a distance that the displacement section travels as the restricting section travels a fixed distance, wherein the ratio of the distance between those restricting points which define a relatively large spacing therebetween becomes longer than the ratio of the distance between those restricting points which define a relatively small spacing therebetween.

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.
