摘要： 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.

摘要： A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes. When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.
摘要翻译：供纸单元包括料斗，板料被堆叠在该料斗上，并且围绕旋转轴转动。料斗被转动以移动或移动到送纸辊。供纸单元具有以下三种模式：其中料斗被转动到最远离送纸辊的大的释放模式，其中打印纸抵靠进纸辊的非释放模式和小的释放打印纸与进纸辊略微分离，并且处于上述两种模式之间的中等水平的模式。当送纸作业仍然存在时，最上面的打印纸与供纸辊稍微分离的状态通过小的释放模式保持，从而使料斗的摆动范围最小化。

摘要： A paper feeding roller is provided in the vicinity of a first widthwise end of a transporting path extending to a recording apparatus. A hopper, for stacking a plurality of sheets of paper, includes an aligning face, on which leading ends of the stacked sheets are abutted to be aligned with each other. The aligning face is narrowed from a first side end thereof to a second side end thereof. Here, the first side end is in the vicinity of the first widthwise end of the transporting path, and the second side end is in the vicinity of a second widthwise end of the transporting path. The hopper includes a guide face provided on the first side end of the aligning face so as to extend parallel with the transporting path. The hopper includes a hopper member pivotably supported on the second side end of the aligning face in a cantilevered manner, so as to move on the aligning face such that distance change in accordance with the number of sheets stacked thereon in the first widthwise end side of the transporting path with respect to the paper feeding roller becomes larger than that in the second widthwise end side of the transporting path. A paper retainer is provided on a paper returner which is placed in the vicinity of an end portion of the hopper which faces the paper feeding roller. The paper retainer has a higher friction coefficient than the paper returner.
