Provided is a drive transmission switching mechanism that can switch and drive two circulation units by one motor in response to a switching operation of a paper sheet transport direction. A paper sheet storage unit includes a first circulation unit 100 and a second circulation unit 200 that respectively receive transported paper sheets upon reception of a drive force from a single motor 302 and feed paper sheets stored therein, a sorter 310 that sorts paper sheets to either one of the circulation units, and a drive transmission switching mechanism 400 that transmits a drive force from the motor to either one of the circulation units. The drive transmission switching mechanism is activated in conjunction with an operation to change the posture of the sorter, thereby switching and transmitting the drive force to either one of the circulation units.

A sheet conveyance apparatus includes a switching member to execute a pivot operation and a conveyance portion to convey a sheet at a first conveyance speed where a driving motor rotates at a first rotational speed, and to convey the sheet at a second conveyance speed which is greater than zero and slower than the first conveyance speed where the driving motor rotates at a second rotational speed which is greater than zero and slower than the first rotational speed. Where a control portion conveys a first sheet at the first conveyance speed, the switching member executes the pivot operation at the second operating speed before the first sheet arrives at the switching member and the conveyance portion, and rotates the driving motor at the first rotational speed after the pivot operation has been executed and before the first sheet arrives at the conveyance portion.

A banknote feeder device (3) configured to interconnect and operate in conjunction with a banknote acceptor apparatus (2), the banknote feeder device (3) comprising a banknote transport mechanism operable, when the banknote feeder device (3) is connected to the banknote acceptor apparatus (2), to transport a banknote from a banknote input aperture to a banknote output aperture. The banknote transport mechanism comprises a linear succession of spaced-apart pairs of transport wheels (22) and each transport wheel extends at least partially through a banknote transport conduit surface into an interior cavity of the banknote transport conduit between the banknote input aperture and the banknote output aperture.

One embodiment of the present disclosure provides a post-processing apparatus for an image forming apparatus which arranges paper ejected from an ejection part of an image forming apparatus on a fence for post-processing. The post-processing apparatus includes a paddle guide which includes a paddle arm to which a paddle wing is coupled and a pusher positioned adjacent to the ejection part and stands by at a home position until the paper is ejected, a driving part which vertically moves the paddle guide, rotates when the paper is ejected from the ejection part to move the paddle guide downward so that the pusher presses the paper downward and drops the paper on a stacking base, and a paddle wing which vertically moves according to a vertical movement of the paddle guide, moves downward according to a downward movement of the paddle guide, arranges the paper dropped on the stacking base toward the fence positioned adjacent to the stacking base, and then, moves upward with an upward movement of the paddle guide according to operation of the driving part, wherein vertical movements of the pusher and the paddle wing are performed by a vertical movement of the paddle guide performed due to single unit periodic operation of the driving part.

A conveyance route switching mechanism and a paper sheet handling apparatus that includes the conveyance route switching mechanism include a driving source, a gate, a first gear, and an internal gear. The driving source includes a driving shaft. The gate includes a gate shaft, and a blade that is provided on the gate shaft, and switches conveyance routes of paper sheets. The first gear is provided on the gate shaft. The internal gear meshes with the first gear. According to rotation of the driving shaft, the gate shaft rotates on an axis of the gate shaft, and revolves with the driving shaft as a rotation center while the first gear meshes with the internal gear.

A processing system includes a stacker on which at least one medium recorded with an image is stacked, a holding unit configured to hold the medium, a processing path extending from the stacker to the holding unit, a pick roller configured to transport the medium from the stacker to the processing path, a reading unit configured to read the medium transported through the processing path, and a control unit configured to store indication data indicating an index of whether to transport a medium to the holding unit, wherein, when receiving a processing instruction from a user, the control unit is configured to cause the pick roller to transport a medium from the stacker to the processing path, and determine whether to transport the medium to the holding unit, based on read data and the indication data, the read data being acquired by reading the medium by the reading unit.

An image forming device including a gate mechanism reduces a noise generated when a sheet is conveyed. The image forming device includes a conveyance path and a gate. The conveyance path is branched into a plurality of paths, and the sheet is conveyed along a conveyance direction. The gate is provided at a position in the conveyance path at which the conveyance path is branched into the plurality of paths, and switches a path through which the sheet is conveyed. The image forming device rotates the gate in a direction in which a contact point of the gate, which faces a front surface of the sheet to be conveyed and is located at a position at which a trailing end of the sheet first comes into contact with the gate, and a front surface of the sheet to be conveyed face each other.

A storing and issuing module (10) including a storage roller (50), a motor (60) associated with the storage roller (50), at least one transport tape (52) configured to wrap onto the storage roller (50) together with flexible documents, such as banknotes, conveyed in a conveying section provided with holding means (53, 54) actuatable for engaging flexible documents to be stored or issued with the transport tape (52), wherein the storing and issuing module (50) is capable of handling large storage capacity thanks to a mechanical layout that minimizes variations in the conveying section despite the great variations of the outer diameter of the storage roller due to the large capacity thereof.

In an image forming apparatus, a sheet is guided into a first conveyor path or a second conveyor path selectively when a first cover is in a closed position, and is ejected onto the first cover when the first cover is in an open position. Upon power-up, a controller causes a first conveyor roller to rotate but if the first cover is in the open position, when a sheet sensor detects a sheet, the controller does not cause a second conveyor roller to rotate, and causes a flapper to swing from a first position to a second position, and when a front end of the sheet reaches a position downstream of an upstream end of the flapper in a conveyance direction of the sheet conveyed by the first conveyor roller, the controller causes the flapper to swing from the second position to the first position.
