A sheet separating apparatus includes a stacker having a sheet supporting surface, a separation roller rotating around a first shaft center parallel to a width direction of the sheet supporting surface, contacting a sheet fed from the stacker and conveying the sheet to a downstream side in a conveyance direction perpendicular to the width direction, a separation piece facing the separation roller and separating the sheet one at a time in cooperation with the separation roller, the separation roller and the separation piece nipping the sheet at a first nip position, and a pinch roller provided on an upstream side with respect to the first nip position and abutting on the separation roller to be rotatable around a second shaft center parallel to the width direction, the pinch roller having a portion overlapping the separation piece as seen from the width direction.

A banknote separating device is applicable for a financial self-service equipment, includes a banknote separating wheel set and a reverse wheel set for cooperating with the banknote separating wheel set, and the reverse wheel set includes a reverse-wheel-set rotating shaft, a reverse wheel fixing frame, and a reverse wheel assembly. One end of the reverse wheel assembly sequentially passes through an E-shaped snap ring, a flanged bearing, a one-way bearing stop ring and a one-way bearing to be mounted to the reverse wheel fixing frame, and the one-way bearing and the reverse wheel fixing frame are coupled by the one-way bearing stop ring to form a stationary rigid body, and the one-way bearing stop ring is in contact with only an outer ring of the flanged bearing.

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 feeding device is disclosed, which comprises a paper passage, a sheet-separating roller, a friction institution, and a stopper. The sheet-separating roller is disposed in the paper passage. The friction institution is disposed in the paper passage opposite to the sheet-separating roller. The stopper is disposed in the upstream side of the sheet-separating roller. The stopper includes an axle, a short arm, and a long arm. The short arm connects to the axle, and the axle acts as a fulcrum. The long arm and the short arm disposed to the axle coaxially. A threshold of the force for pushing the short arm is larger than a threshold of the force for pushing the long arm.

When waiting for printing, a cam that rotates together with the rotation of a gear locks a knurl at position on the upstream side in the sheet conveyance direction, which prevents sheets from dropping down. Moreover, during printing, when the cam is rotated 180 from the locked position, the knurl is in a state capable of sliding toward the downstream side. As a result, with the force that returns the knurl to the upstream side being too small, it is possible to prevent feeding overlapping sheet due to the front end of a sheet further on the down side than a sheet being fed from dropping toward the downstream side further than the knurl.

Disclosed is a cheque processing device, including: a base, a frame located at the top face of the base and forming a U-shaped paper passage, and multiple sets of conveying roller assemblies (9) and multiple processing mechanisms provided along the U-shaped paper passage, wherein one end of the U-shaped paper passage is an inlet and the other end is an outlet. The frame comprises a fixed frame body, and a first movable frame body and a second movable frame body which form the U-shaped paper passage together with the fixed frame body, wherein the first movable frame body and the second movable frame body can both pivot on the base to open and close with respect to the fixed frame body.
