A sheet transport apparatus includes a first casing in which a transport path is formed; a transport unit which transports a sheet along the transport path; a second casing which is provided to be movable with respect to the first casing; a sheet support unit which is rotatably provided in the first casing at a position on a side to which the second casing is moved, the sheet support unit being changeable between a first state, a second state, and a third state and supporting the sheet at least in the third state; and an urging unit which urges the sheet support unit toward the first state within a range from the first state to the second state and which urges the sheet support unit toward the third state within a range from the second state to the third state.

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.

User labor relating to determining on an alignment condition is reduced and a stable conveying operation is realized by aligning a sheet bundle also when a sheet bundle is added. A sheet bundle composed of multiple sheet materials is placed on a loading platform. An encoder pulse unit detects the amount of the sheet bundle placed on the loading platform based on the opening amount of a pressure plate. A control unit determines on an alignment condition according to the amount of the sheet bundle. Rotating members align the sheet bundle in accordance with the alignment condition. When it is determined that another sheet bundle has been added to the loading platform, the control unit updates the alignment condition according to the total amount of the other sheet bundle and the sheet bundle remaining on the loading platform.

A sheet conveyer device, including a transmitter to transmit ultrasonic waves arranged on a conveyer path to face a first side of a sheet; a receiver to receive the ultrasonic waves arranged on the conveyer path to face a second side of the sheet; a measurement unit to measure an intensity of the received ultrasonic waves; and a determination unit to determine a condition of a range in the conveyer path between the transmitter and the receiver among a first condition, wherein no sheet is present in the range, a second condition, in which a sheet is present in the range, and a third condition, in which a plurality of sheets are present in the range, based on intensities of the ultrasonic waves measured by the measurement unit in a plurality of periods separately after transmission of the ultrasonic waves, is provided.

A feeder includes a pressing section that presses a medium after a feeding force is applied on the medium in a direction in which a leading edge of the medium set in a setting section in a feeding direction abuts on an abutment section during feeding of the media by a feed roller.

A separator that separates a plurality of media to convey the medium, and at least one first guide member that guides the media to the separator are provided, the separator includes a conveying roller and a separation roller configured to nip the media in a nip range, and a tip of the first guide member that guides the media is located at a position that does not overlap the separator when viewed from a conveyance direction and that overlaps the nip range when viewed from an axial direction of the separation roller.

A card feeder including a frame, a reservoir receiving a stack of cards, a separation system including a separation roll, a ballast movable on the frame between a support position on the top of the stack and a stowed position on one side of the stack, a door movable on the frame between an open position and a closed position, a transmission system for moving the ballast from the support position into the stowed position when the door passes from the closed position into the open position, and a return system arranged so as to return the ballast back to the support position when it is in the stowed position.

A medium housing device includes: a frame including an internal space; a partitioning plate that partitions the internal space so as to intersect with a specific collection direction, and that forms a collection space in which the medium is collected along the collection direction; a partitioning plate moving section that moves the partitioning plate along the collection direction; a side guide that is attached inside the frame and that determines the size of the collection space in an intersecting direction intersecting with the collection direction; a positioning portion that positions an end portion of the side guide at one attachment position selected from a plurality of attachment positions; and a retention switching portion that switches between a retained state in which the end portion of the side guide is positioned, and a retention-released state in which the end portion of the side guide is not positioned.

A banknote separation device includes a banknote separation wheel set and a reverse wheel set. The reverse wheel set includes a reverse wheel component, a reverse wheel set rotation shaft, a first fixing frame and a second fixing frame. Two ends of the reverse wheel set rotation shaft are fixed on two mounting side plates respectively, the first fixing frame and the second fixing frame are respectively fixedly connected at two ends of reverse wheel component. The first fixing frame is provided with two lash adjusting threaded holes and a first lash adjusting screw, the second fixing frame is provided with a second lash adjusting threaded hole and a second lash adjusting screw cooperating therewith, and radial clearances between two ends of the reverse wheel component and the banknote separation wheel set are adjusted respectively by the two lash adjusting screws.

A banknote-passing type banknote conveying device, used at a banknote inlet-outlet of an automatic teller machine, includes a mounting lateral plate, a banknote stacking mechanism, a banknote clamping and conveying mechanism, a pressing mechanism, a jacking mechanism, and a central control unit for controlling the operation of the above mechanisms. The banknote-passing type banknote conveying device uses a lifting motor and a connection rod to drive a lifting plate to move the banknotes up and down, and uses a pressing plate to move the banknotes back and forth. The functions of stacking and passing banknotes are achieved in an effective space. Moreover, a pull type electromagnet and a spring are used to control the opening and closing of the banknote clamping and conveying mechanism, thus a traditional motor control method and the like can be omitted, such that the cost is low, and the reliability is high.
