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 apparatus includes first and second sheet sensors provided in order from upstream to downstream sides in feeding direction on a paper feed path, sheet conveyor roller sets arranged along the path, and a roller controller individually controlling groups of rollers on the upstream and downstream sides of the first sheet sensor, in response to a change in values of output signals from first and second sheet sensors. The roller controller includes an overlapped feeding determining device outputting a determination signal assuming a first value when overlapped feeding occurs and a second value otherwise, in response to the change in values of the output signals from the sensors, an overlapped feeding eliminating device eliminating overlapped feeding by controlling the roller controller upon receiving the determination signal of the first value, and a conveyor roller stopping device stopping the sheet conveyor rollers if the overlapped feeding eliminating process should fail.

摘要： In the present glossy paper, an opposite surface of a glossed and smooth image formation surface is rough-surfaced. Therefore, the glossy paper do not adhere together even under the high-temperature and high-humidity environment. In fact, the present invention provides glossy paper which can advantageously achieve a continuous paper feeding in the image forming apparatus regardless of the use environment conditions.
