A paper sheet handling apparatus includes a conveyance path where a paper sheet, which is inserted through an insertion port, is introduced to a feeding position and the paper sheet is fed from the feeding position into an interior of its own apparatus, an introduction mechanism that has a conveyance belt and introduces the paper sheet, which is inserted through the insertion port to the feeding position, a feeding mechanism that feeds the paper sheet, which is delivered to the feeding position by the introduction mechanism, and a controller configured to control the introduction mechanism and the feeding mechanism. The controller controls the feeding mechanism in such a manner that the paper sheet, which is inserted through the insertion port, is fed when the paper sheet is not introduced to the feeding position after the introduction mechanism repeats, a predetermined number of times.

A sheet feeding unit, attached to a sheet feeding apparatus that feeds a sheet, includes an endless belt, first and second rotary members, and a holding device. The endless belt contacts a sheet stacked on a stacking device to feed the sheet. The first and second rotary members contact an inner periphery of the endless belt to support the endless belt. The second rotary member faces, via the endless belt, a separation device that separates the sheet from the endless belt. The holding device holds the first and second rotary members. The endless belt includes protruding and depressed portions on the inner periphery. The second rotary member includes protruding and depressed driving portions that mesh with the protruding and depressed portions to transmit a driving force to the endless belt to, in turn, rotate the endless belt to feed the sheet in contact with the endless belt.

A sheet-feeding device includes: a first feeding roller configured to contact a sheet accommodated in a sheet-accommodation portion to feed the sheet; a second feeding roller movable between a non-feeding position and a feeding position; a driving source configured to generate a rotational driving force to the first feeding roller; a transmission portion configured to transmit the rotational driving force to the second feeding roller; a first sensor; a second sensor; and a roller actuating portion. The roller actuating portion is configured to: move the second feeding roller from the non-feeding position to the feeding position in a case where the second detector detects rotation of the first feeding roller is stopped during a sheet-feeding operation; and move the second feeding roller from the feeding position to the non-feeding position in a case where the first sensor detects the sheet-feeding operation is completed for the sheet.

A banknote separation apparatus, for a banknote bundle receiving machine, includes a guide unit, a pickup roller unit, a pickup roller raising/lowering unit, a feeding roller unit and a gate roller unit. The guide unit is provided on a route along which a banknote bundle inputted into the banknote bundle receiving machine is moved. The pickup roller unit is provided above the guide unit in a spaced-apart relationship with the guide unit and configured to separate a banknote from the banknote bundle and to feed the banknote. The pickup roller raising/lowering unit is configured to raise or lower the pickup roller unit. The feeding roller unit is provided on a back side of the pickup roller unit. The gate roller unit is provided under the feeding roller unit and configured to maintain a predetermined distance from the feeding roller unit.

A first sheet product 1 is gripped between an additional conveyor 2 and a feeding conveyor 3 at a downstream end of the additional conveyor 2. Subsequently, subsequent sheet products 1 are moved back by the feeding conveyor 3 to he separated from the first sheet product 1. Subsequently, the first sheet product 1 is supplied by the additional conveyor 2.

A method and apparatus for processing documents are provided. The apparatus includes a feeder for receiving a packet of a plurality of documents and separating the documents to serially feed the documents to a scanner. A retard adjacent the feeder is operable in first and second positions. In the first position the retard forms a nip with the feeder so that the retard is operable to impede the progress of one or more documents in the packet while the feeder feeds one of the documents in the packet. In the second position, the retard is spaced apart from the feeder to form a gap between the feeder and the retard. The system further includes a sensor for detecting a characteristic of the documents in a packet indicative of whether the number of documents in the packet exceeds a predetermined threshold. A drive mechanism automatically drives the retard pad between the first and second positions in response to the detected characteristic

The present disclosure is generally related to an apparatus having cutter elements for destroying articles such as paper sheets and a mechanism for separating at least a sheet from a stack in a tray. A paper feed mechanism feeds paper that is separated from the stack by a stack separation mechanism to the cutter elements. The feed and separation mechanisms can be activated by rotation of the cutter elements. In one embodiment, the stack separation mechanism moves in an alternating manner between retracted and extended positions to disengage and engage and insert the stack to separate (with its edge) paper therefrom to feed to the feed mechanism for shredding. The paper stack separation mechanism can move in an non-undulating manner relative to the stack. A device for stripping stapled pages, a pivotable support plate, and pressure plate can also be used, as well as a number of sensors.

A sheet feeder comprises a roller configured to rotate about an axis and an input drive configured to deliver single sheets to the roller such that a leading edge of each sheet is substantially parallel to the axis. The roller comprises a plurality of flexible fins extending along the axis. As the roller rotates, one of the sheets can be lifted by the rotating fins to pass over the roller, while the leading edge of a following sheet is delivered to the roller in an underlapping relationship with the first sheet.
