11142418 · 2021-10-12 · ·

An image forming device comprising: a tray in which multiple number of sheets are stored; a feeder that feeds the sheet stored in the tray; and a hardware processor that: measures a carrying speed of the sheet fed by the feeder; determines whether or not the measured carrying speed is affected by the following sheet; corrects the carrying speed upon determining the carrying speed is affected by the following sheet; and detects a wear status on the feeder based on the measured carrying speed or the corrected carrying speed.

APPARATUS AND METHOD TO RESTORE PAPER STACK INTEGRITY

A paper feed apparatus. The paper feed apparatus can include a stack of paper, the stack of paper having an uppermost sheet of paper and a second sheet of paper being disposed below the uppermost sheet of paper. A driven pick roller is suitably arranged in contact with the uppermost sheet of paper and is suitably rotatable in a first roller direction to convey the uppermost sheet of paper in a first paper direction. A nip defined by a driven feed roller and a separation roller is suitably disposed downstream from the pick roller, the nip having a gap sufficient for the uppermost sheet of paper to pass through, the gap being sufficient for the separation roller to be in frictional engagement with the second sheet of paper to prevent it from passing through the nip. A rotating element having a plurality of radially extending brush elements is suitably disposed between the driven pick roller and the driven feed roller and rotatable in a second direction opposite the first roller direction to urge the second sheet of paper under the influence of the plurality of radially extending brush elements in a second paper direction opposite the first paper direction.

10202249 · 2019-02-12 · ·

A sheet feeding device includes a stacking unit, a feeding unit, a rotating member, a separation unit, a holding unit, a swinging member, and a guiding unit. The stacking unit stacks sheets. The feeding unit feeds stacked sheets. The rotating member conveys sheets, and is on a feeding unit downstream side. The separation unit separates fed sheets one by one, and contacts the rotating member. The holding unit holds the feeding unit and rotating member, and is rotatable about a rotating member rotation shaft. The swinging members swingably disposed on the holding unit and the guiding unit on a swinging member lower side guides the sheets with contact. A first contact portion of the swinging member and the guiding unit is on a second contact portion upstream side, that is a rotating member/separation unit contact portion. A swinging member swinging shaft is on the first contact portion upstream side.

Medium supplying apparatus
10189662 · 2019-01-29 · ·

A medium supplying apparatus includes a control unit. The control unit executes: a first control in which, in a case where a double feed detecting sensor detects a double feed of media, rotation drive of a separator roller is stopped, and a retard roller is caused to convey the media to an upstream side in a conveying direction; and a second control in which, after the execution of the first control, the rotation drive of the separator roller is restarted, and, in a case where the double feed detecting sensor detects a double feed of the media, a conveying load applied is set to be higher than that at the time of detecting the double feed before the execution of the first control, the rotation drive of the separator roller is stopped, and the retard roller is caused to convey the media to the upstream side in the conveying direction.
