A printing apparatus includes a printing unit that prints an image on a sheet by using ink, a feed path along which the sheet is transported toward the printing unit, a switchback mechanism that, when two sides of the sheet are to be printed, switches back the sheet of which one of the two sides has been printed and sends the sheet to the feed path, and a correction roller pair capable of correcting skew of the sheet by having firm contact with the sheet transported along the feed path.

A sheet feeder includes: a feed roller; a shutter movable between a restricting position restricting a leading edge of a sheet and a non-restricting position releasing the restriction on the sheet; and a controller configured to control rotation of the feed roller and movement of the shutter. The controller is configured to perform: a first feeding process of controlling the feed roller to rotate at a first rotational speed while the shutter is at the restricting position and of controlling the shutter to move to the non-restricting position from the restricting position no earlier than rotation of the feed roller at the first rotational speed: a reduction process of controlling a rotational speed of the feed roller to be less than the first rotational speed; and a second feeding process of controlling the feed roller to rotate at a second rotational speed.

A conveyor includes: a first roller; a second roller opposed to the first roller; a roller holder including a roller supporter; a frame supporting the roller holder and having a first surface and second surface; and a moving member that is moved to move the roller supporter. The roller holder includes: a contact portion that is located upstream of the roller supporter in a conveying direction and contacts the second surface; a thin portion disposed between the roller supporter and the contact portion; and an engaging portion engaged with the moving member at a position located downstream of the thin portion in the conveying direction. The roller supporter is moved from a first position to a second position by bending of the thin portion, which bending is caused when the engaging portion is moved away from the second roller with movement of the moving member.

A sheet conveyor including a separation roller, a separation pad, an urging member urging the separation pad, and a feed roller unit disposed downstream relative to the separation roller in a conveyance direction, the feed roller unit including a first outer circumferential surface disposed on a first side in a width direction perpendicular to the conveyance direction, a second outer circumferential surface disposed on a second side opposite to the first side in the width direction, and a concave portion disposed between the first and second outer circumferential surfaces in the width direction, the concave portion being recessed inward in a radial direction of the first and second outer circumferential surfaces from the first and second outer circumferential surfaces, an urging member being disposed upstream relative to the concave portion in the conveyance direction and disposed between the first and second outer circumferential surfaces in the width direction.

A sheet conveying apparatus, including: a base body having a conveyor surface; a separating roller configured to rotate about a first rotation axis parallel to a width direction of the conveyor surface and to convey a sheet downstream in a conveyance direction orthogonal to the width direction; a separating piece opposed to the separating roller and configured to cooperate with the separating roller to separate sheets being conveyed one by one; an attachment member removably attached to the base body at a position at which the attachment member is opposed to the separating roller, so as to form a part of the conveyor surface; a holder holding the separating piece and supported by the attachment member so as to be movable toward and away from the separating roller; and a first urging member provided between the attachment member and the holder for urging the separating piece toward the separating roller.

A ridged paper ejection roller according to the present invention conveys a paper sheet in cooperation with a plurality of star wheels disposed apart from each other in a width direction of the paper sheet, and includes a rigid main shaft body and a resin body coated on the main shaft body. The resin body integrally includes a plurality of large diameter-regions that work in conjunction with the respective star wheels to hold therebetween and convey the paper sheet, and small-diameter regions other than the large-diameter regions.

A paper feeding device comprises a storage surface for a stack of papers and being adapted to be move vertically between a first, lower end position and a second, upper end position, and a feeding roll for feeding papers from their position on the storage surface and imparting an uppermost sheet of paper a horizontal displacement. A first mounting device comprises a first vertically movable, preferably pivotable housing adapted to mount or suspend a first end of the feeding roll, and a second mounting device comprises a second vertically movable, preferably pivotable housing adapted to mount or suspend a second end of the feeding roll opposite to the first end of the feeding roll. By providing the first and second housings pivotable independently of each other and an intermediate axle, the feeding roll adapts to a non-uniform stack of papers, improving the reliability of the feeding.

A sheet conveying apparatus, including: a base body having a conveyor surface; a separating roller configured to rotate about a first rotation axis parallel to a width direction of the conveyor surface and to convey a sheet downstream in a conveyance direction orthogonal to the width direction; a separating piece opposed to the separating roller and configured to cooperate with the separating roller to separate sheets being conveyed one by one; an attachment member removably attached to the base body at a position at which the attachment member is opposed to the separating roller, so as to form a part of the conveyor surface; a holder holding the separating piece and supported by the attachment member so as to be movable toward and away from the separating roller; and a first urging member provided between the attachment member and the holder for urging the separating piece toward the separating roller.

A sheet-type medium separating apparatus applicable in a self-service financial device for reliable sheet-by-sheet separation of an entire stack of banknotes. The apparatus includes a pickup roller component; a reversal roller component; and a separation roller component, where the reversal roller component includes a reversal roller, the reversal roller is fitted onto a reversal roller shaft via a one-way bearing, the reversal roller is provided with an inner sleeve cylinder fixed with the one-way bearing and a reversal roller sleeve sleeved onto the inner sleeve cylinder and capable of moving axially and flexibly. The separating apparatus allows for automatic adjustment of the meshing clearance between the reversal roller and the separation roller on the basis of the thickness of sheet-type media to be separated, thus effectively solving the problem of the sheet-type media being jammed or torn.
