A sheet feeder includes: a first roller; a separation member; a shutter; a pressing portion; and a cam portion. The separation member contacts the first roller at a contact position. An axis of the shutter is positioned downstream of the separation member in a conveying direction. The shutter is movable between first and second positions. The shutter in the first position has a portion positioned upstream of the contact position in the conveying direction. The pressing portion is positioned upstream of the separation member and the shutter in the first position in the conveying direction. The pressing portion is movable between third and fourth positions. The pressing portion in the third position faces the first roller. The pressing portion in the fourth position is separated from the first roller farther than in the third position. The cam portion is positioned upstream of the pressing portion in the conveying direction.

A sheet feeding device comprising: a stacking member on which a sheet is stacked; a first conveying portion that conveys a sheet stacked on the stacking member; a second conveying portion that separates and conveys a sheet conveyed by the first conveying portion; a stopper member that stops a sheet whose front end is abutted against the stopper member at an upstream of the second conveying portion in a sheet conveying direction, wherein the stopper member can be at a first position where the sheet can be stopped and a second position where the sheet can pass the stopper member, and wherein the stopper member can move from the first position toward the second position such that a sheet conveyed by the first conveying portion reaches the second conveying portion while maintaining a state where the front end of the sheet is abutted to the stopper member.

A feeding apparatus includes a mounting portion that holds a medium; a feeding roller that feeds the medium toward a feeding direction; a stopper configured to prevent the medium from moving toward the feeding direction; a supporting part that swings the feeding roller between: a first position in which the feeding roller feeds the medium while both the feeding roller and the stopper contact the medium, and a second position in which the feeding roller does not contact the medium while the stopper contacts the medium to prevent the medium from moving toward the feeding direction; and a regulating part disposed on a downstream side in feeding direction with respect to a supporting point of the supporting part. The regulating part regulates movement of the stopper by contacting a portion of the stopper that does not contact the medium in the first position.

An object of the invention is to provide a sheet materials separation-aiding apparatus capable of creating a gap between a specific sheet material and a sheet material coming into contact with the lower surface thereof even when the location precision of a stack of laminated sheet materials is low in the height direction of the stack of laminated sheet materials and in the direction orthogonal to the height direction.

In order to improve the ability to feed paper currency from a deposit unit and to reduce the height of the device, this paper currency handling device (100) has a paper currency recognition unit (170) and a paper currency storage unit (200) (which does not include a deposit unit (120) and a withdrawal unit (140)) accommodated within a chassis section (112) of a vault (110), so that deposited paper currency is transported to the paper currency storage unit (200) and withdrawn paper currency is transported from the paper currency storage unit (200) as the paper currency passes through the chassis section (112). When the paper currency (B) is fed to a feed path unit (124) connecting the deposit unit (120) and an upstream deposit path (181), the vanes (129) of impellers (128) make contact with the paper currency (B) retained in the deposit unit (120), with the contact being on the feed path unit (124) side.

Regarding a restricting member that includes a contact face configured to be brought into contact with at least one portion of edges of a bundle of media mounted on a medium mounting section, and that is configured to be switched to either a blocking attitude for blocking advancement of the edges of the bundle of media into a nip portion between a feeding roller and a separating roller or an opening attitude for permitting the advancement of the edges of the bundle of media into the nip portion, the restricting member allows, in the blocking attitude, an edge shape of the bundle of media in contact with the contact face to be formed into a shape that fills in a tapered space tapering toward the nip portion.

A sheet detection unit includes a photo-interrupter, a shutter holder, and shutter members held to be movable relative to the shutter holder. The shutter members include a sheet rear end detection portion capable of switching an optical axis between a light-interrupted state and a light-transmitted state and each are supported to be movable to an abutment position where the shutter member causes an abutment surface to protrude, and also movable to a retracted position where the shutter member is retracted from a sheet conveyance path. Based on a detection signal output from the photo-interrupter by the sheet front end detection portion and the sheet rear end detection portion moving relative to the optical axis, a control unit determines the presence or absence of a sheet.
