  • Patent number: 10457510
    Abstract: A recording apparatus includes a return member switchable between a first orientation in which a portion of the return member overlaps a feed roller in a side view of a medium feeding path and a second orientation in which the return member is turned toward a downstream side in a medium feeding direction and does not overlap the feed roller. The return member changes an orientation thereof from the second orientation to the first orientation, thereby returning a medium to an upstream side in the medium feeding direction. When a transport roller disposed downstream of the feed roller is driven in reverse to return the medium to the upstream side and position the medium at a recording start position, the return member takes a third orientation in which the return member is raised toward the upstream side further than in the first orientation.

  • Patent number: 10144602
    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.

The arm pivots between a first arm position, and a second arm position. The return guide pivots between a first return guide position, and a second return guide position. A space occupied by the return guide in the first return guide position overlaps a space occupied by the arm in the second arm position. The return guide is in the second return guide position when the arm is in the second arm position which is retracted from an insertion space occupied by the tray.

  • Patent number: 8570622
    Abstract: A method of monitoring a sequence of documents passing along a transport path is described. The method including: operating a radiation transmitter with a control signal at a first, working, level to cause radiation at a first intensity to impinge on one side of a document as it passes an inspection position in the transport path; receiving at a radiation receiver, radiation from the transmitter that has passed through the document, the radiation receiver generating an output signal with a level related to the intensity of the received radiation; and monitoring the output signal to detect the presence and/or a characteristic of the document.

  • Patent number: 8511667
    Abstract: An automatic document feeder includes a paper pick-up device, a first roller assembly, and a second roller assembly. The first roller assembly includes a first shaft, a first roller, and a power coupling device. When the power coupling device is connected with the first shaft and the first roller for transmitting a paper, the first roller is driven to be rotated by the first shaft. When the front edge of the paper is moved to the second roller assembly, the first roller is driven to be rotated at a higher speed by the paper. Consequently, a power connection between the first roller and the first shaft is released by the power coupling device. Then, the first roller reaches a static status in order to correct the skew phenomenon of the next paper.

  • Patent number: 8430393
    Abstract: When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.

  • Patent number: 8358448
    Abstract: A scanning device includes a transparent platen, a scanning module, a document transporting mechanism and a flexible pressing member. The scanning module is located in a scan zone and acquires through the transparent platen an image of a document. The document transporting mechanism transports the document along a passageway and across the scan zone. The flexible pressing member is disposed in the passageway, upstream of the scan zone or within the scan zone and located apart from the transparent platen by a gap. The flexible pressing member is deformed in a direction away from the transparent platen due to a force applied by the document transported across the scan zone.
