Abstract: There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

Abstract: A recording-medium feeding device includes a container, a separating mechanism, and a suppressing member. The container accommodates recording media. The separating mechanism includes a driving member, a separating member, and a torque limiter. The driving member comes into contact with and delivers an uppermost recording medium. The separating member separates the recording media one-by-one. When a rotational torque smaller than a predetermined rotational torque is applied to the torque limiter, the torque limiter repels a load of the rotational torque to inhibit rotation of the separating member. When a rotational torque larger than or equal to the predetermined rotational torque is applied to the torque limiter, the torque limiter allows the separating member to be rotationally driven in accordance with the load. The suppressing member suppresses receding movement of the recording media caused by reverse rotation of the separating member when the driving member stops.

Abstract: A sheet feed device has a tray with holding surface for holding sheets, a feed unit for feeding sheets from the tray, and a separation plate. The separation plate has an inclined surface and two or more separation portions that separate a sheet from the sheets held in the tray. At least one of the separation portions projects a first distance from the inclined surface. The separation plate also has a projection positioned on the inclined surface that projects a second distance from the inclined surface. The second distance is greater than the first distance. A first of the separation portions is positioned upstream of the particular projection in the sheet feed direction, and a second of the separation portions positioned downstream of the particular projection in the sheet feed direction.

Abstract: A sheet feeder comprises a sheet stacking unit which stacks sheets, a sheet pickup unit which picks up a sheet from one side of the stacked sheets on the sheet stacking unit, a sheet separating and feeding unit which separately feeds sheets one by one to a conveyance path, an orientation holding unit which holds a feed orientation of a sheet, and a biasing unit which biases the orientation holding unit from a retracted position to a projecting position. A projection amount of the orientation holding unit from an inclined surface increases as the number of stacked sheets decreases, and the projection amount from the inclined surface decreases as the number of stacked sheets increases.
