    摘要: A transport device configured to transport a medium stacked on a loading section is disclosed. The transport device includes a transport roller and a separation roller and is configured to separate the medium one sheet at a time. A rotation shaft is attached to the separation roller and a movable guide member guides the medium between the transport roller and the separation roller, to be aligned with the separation roller in a shaft direction of the rotation shaft, and to be movable in the shaft direction. The separation roller is attachable to and detachable from the rotation shaft by moving in the shaft direction. By moving in the shaft direction, the movable guide member is displaced between a guide position at which the medium is guided and a retracted position at which the separation roller is movable in the shaft direction with respect to the rotation shaft.

    摘要: An image forming apparatus includes a paper feeding cassette, a first conveying unit, a lift mechanism, a motor, a second conveying unit, and a control unit. The controller drives the motor and, if a value indicating a movement amount of the tray moving from when the lift mechanism starts the lifting of the tray until when a position of the top part reaches a first position is a first value, matches a position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a second position and, if the value indicating the movement amount is a second value larger than the first value, matches the position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a third position lower than the second position.

    摘要: Provided are a medium conveying apparatus to able to satisfactorily feed a medium. A medium conveying apparatus includes a loading tray, a feed roller to feed a medium placed on the loading tray, a separation roller located above the feed roller to face the feed roller, a bottom surface guide located at a first position where contact between a bottom surface of the medium placed on the loading tray and the feed roller is restricted, before medium feeding, and located at a second position where contact between the bottom surface of the medium placed on the loading tray and the feed roller is allowed, at a time of medium feeding, a first guide engaged with the bottom surface guide located at the first position to restrict contact between a front edge of the medium placed on the loading tray and the separation roller, before medium feeding, and a second guide located between an upstream edge of the separation roller in a medium conveying direction and a central part of the separation roller to regulate the front edge of the medium at a position apart upwardly by a predetermined distance from a nip part of the feed roller and the separation roller, at a time of medium feeding.

    摘要: A media feeding apparatus includes: a feed roller, a separation roller, and a pressing portion to press one of the feed roller and the separation roller against the other to form a nip region. A surface of the feed roller has grooves extending in a width direction of the feed roller. The grooves are arranged with a pitch such that at least one groove is always present in the nip region during feeding of the medium. A width of each groove is 0.5 mm or greater and is set such that a contact area ratio is 0.5 or greater, the ratio being a value obtained by {(a surface area of the feed roller in the nip region−an area of the at least one groove of the feed roller in the nip region)}/(the surface area of the feed roller in the nip region). A surface of the separation roller has grooves extending in a circumferential direction of the separation roller.

    摘要: An image processing apparatus includes: a support surface configured to support a sheet, a sheet feeding roller configured to feed the sheet in a conveying direction, a separation member for separating the sheet one by one and positioned downstream of the sheet feeding roller in the conveying direction, and a regulating member displaceable between a first position where the regulating member abuts against a distal end of the sheet supported by the support surface to regulate passage of the sheet in the conveying direction between the sheet feeding roller and the separation member and a second position that is farther from a conveyance path than the first position and that allows passage of the sheet in the conveying direction. The regulating member has a wall surface that abuts against the distal end of the sheet and includes at least one protrusion on the wall surface.

    摘要: A document feeder constituting an image forming apparatus includes a paper feeder to supply a document to a document transport path, a first transporter to transport the document toward image reading positions, and a second transporter to transport the document toward the document discharging tray while supplying the document to the image reading positions. Furthermore, the document feeder includes a motor provided on the first frame, a first driver provided on the first frame and to transmit driving force generated by the motor to the paper feeder and the first transporter, a second driver provided on the second frame and to transmit the driving force generated by the motor to the second transporter, and a second driver to transmit the driving force generated by the motor to the second transporter, and a relay transmission member to transmit the driving force generated by the motor to the second driver.
