With respect to a paper gathering and feeding method or a device therefor performing a gathering process for dropping paper to be transferred in a transfer section to gather the same in a gathering section, and a feeding process for feeding the paper gathered in the gathering section to the transfer section, a rotation member provided with a changeable piece changeable with a radius distance between a tip section and a rotation axis is provided in the vicinity of a coupling section between the transfer section and the gathering section, and at the time of the gathering process, the rotation member is so formed as to rotate in a gathering direction to slap down the paper using the changeable piece with the wider radius distance, and at the time of the feeding process, the rotation member rotates in a feeding direction to perform the feeding allowance operation to allow the paper to be fed.

The feeding apparatus 50 includes a hopper 51 that is provided operable to support the papers in inclined attitude and pivot around a pivot axis 51a, and a feed roller 53 that is provided at a feed roller shaft 54 and feeds the paper to the downstream side by rotating in contact with the paper. When seen from the side view of the feeding path, guide rollers 57 and 58 are provided near the feed roller 53 and are driven to rotate in contact with paper. A movable member, provided near the feed roller 53, pivots around a pivot axis 63a so that the movable member moves backward and forward to the feeding path. Accordingly, a clearance between the feed roller 53 and the hopper 51 is narrowed.

A paper separation mechanism that requires no complicated design or manufacturing and prevents feeding of a plurality of sheets of paper simultaneously to assure sheet-by-sheet feeding of paper, and a paper feed apparatus using such a paper separation mechanism. In the paper feed apparatus, paper is fed sheet by sheet by cooperation of a paper feed roller and the paper separation mechanism which is abutted by the lower end of the paper stacked in an inclined state. The paper separation mechanism is provided with a plurality of projections which are abutted by the lower end of the paper and a plurality of arm portions holding the projections, respectively. Since each projection is not affected by the neighboring projection, load imposed by the paper on the each projection can be controlled independently by the corresponding arm portion.

A recording-sheet supplying apparatus which supplies recording sheets one by one in a sheet-supply direction, including: a first sheet tray that accommodates first recording sheets; a second sheet tray disposed above the first sheet tray and configured to accommodate at least one second recording sheet; an arm provided so as to be pivotable about a pivot axis located above the second sheet tray, and so as to be in a posture in which a distal end of the arm is located downstream of the pivot axis in the sheet-supply direction; a first sheet-supply roller provided at a first portion of the arm; and a second sheet-supply roller provided at a second portion of the arm nearer to the pivot axis than the first portion, wherein where the second sheet tray is on an upstream side in the sheet-supply direction, only the first sheet-supply roller contacts an uppermost first recording sheet, and where the second sheet tray is on a downstream side in the sheet-supply direction, only the second sheet-supply roller contacts an uppermost second recording sheet.

A sheet-supply device includes a pair of stopper members provided to a bottom plate of a hopper portion so as to move between a protruding position where upper surfaces of the stopper members protrude from a surface of the bottom plate and a retracted position where upper surfaces of the stopper members retract from the surface of the bottom plate, and a position change mechanism moving the stopper members between the protruding and retracted positions. By changing a timing of ascending the stopper members to the protruding position according to a type of the sheets to be fed, an appropriate resistance is applied to all of the sheets in the hopper portion except a topmost sheet during a sheet feed operation, thereby preventing a multi-feed problem. The stopper members moves up and down several times via the position change mechanism at a time between after the sheet feed operation is completed and before a next sheet feed operation starts, thereby positioning the sheets, which may cause the multi-feed problem, at a predetermined sheet holding position.
