  • Patent number: 10787007
    Abstract: A printing device includes a discharging roller, opposing rollers opposing the discharging roller, a discharge motor, a first coupling mechanism, a moving mechanism, and a second coupling mechanism. The first coupling mechanism rotates the discharging roller in a direction where a tape is transported downstream when the discharge motor rotates forward (arrow R1). The moving mechanism moves the discharging roller to a nip position to hold the tape with the opposing rollers and a release position spaced from the tape. The second coupling mechanism includes a one-way clutch that couples the discharge motor and the moving mechanism in a manner drivable together when the discharge motor rotates reversely (arrow R2) and decouples the discharge motor from the moving mechanism when the discharge motor rotates forward (arrow R1).

  • Patent number: 8582184
    Abstract: An image reader and document conveying method shorten times necessary for a discharge process that discharges a document in being conveyed and for an idle feeding process of a document that is left on a paper feed tray. If during double-sided reading, a stop key is operated to issue an instruction to cancel reading, a conveyance controller outputs a path specifying signal to select a single-sided path, and thereby a conveyance route is switched from a double-sided path to the single-sided path. For this reason, the discharge process that discharges a document being conveyed at the time of the reading cancellation to a paper discharge tray, and the idle feeding process that discharges a document left on a paper feed tray to the paper discharge tray are performed with use of the single-sided path that is shorter than the double-sided path, and therefore the times necessary for the discharge and idle feeding processes can be shortened.

  • Patent number: 8144377
    Abstract: The present invention relates to a duplex scanning apparatus. The duplex scanning apparatus includes a sheet input tray for placing a stack of documents thereon. For performing duplex scanning operations on the stack of paper sheets, the documents are successively scanned from the bottommost one to the uppermost one. As a consequence, the scanned documents are stacked in the sheet ejecting tray in the same order as that of the original stack.

    Abstract: An image reading apparatus and an image forming apparatus including the same to improve a transferring path of a document to prevent curl from being generated in the document and to prevent interference between a document having both surfaces scanned and a previously discharged document. The image reading apparatus includes a scan path having one end connected to a document supplying unit and the other end connected to a document discharging unit, a scan unit to read information recorded on a document passing through the scan path, a two-sided document branch path to branch from the scan path so that the document whose first surface is scanned by the scan unit passes through the two-sided document branch path before the document is reversed for a two-side scanning process, and a two-sided document transferring path having one end connected to the two-sided document branch path and other end connected to the scan path.

  • Patent number: 7973985
    Abstract: A scanning device scans both sides of a document. The document is fed between a first image sensor module and a second image sensor module. The second image sensor module is moved with respect to the first image sensor module so that a separation distance between the second image sensor module and the first image sensor module is based on a thickness of the document. A first side of the document is scanned using a first scan line located in the first image sensor module. A second side of the document is scanned using a second scan line located in the second image sensor module. When the document is fed between the first image sensor module and the second image sensor module, the document does not reach the first scan line and the second scan line simultaneously.

  • Patent number: 7946578
    Abstract: In an automatic original conveying device, a motor rotates in a single direction and a driving force transmission mechanism transmits the driving force of the motor from a sheet feeding roller to a switchback roller. The sheet feeding roller conveys an original that stands by in a switchback conveying path to a second conveying path. A sorting unit sorts the original conveyed from a paper delivery path to an original delivery table or to the switchback conveying path. The switchback roller is provided between the sorting unit and the switchback conveying path and it is rotatable in a normal direction or a reverse direction.

  • Patent number: RE42269
    Abstract: A double side scanner module which consists of a U-shaped inversion device and two image information reading devices is provided for reading images on the two sides of an original in a single pass. The U-shaped inversion device has two ends for providing a paper feeding path and a paper output path respectively. The two ends are at the same side for the convenience of operation. At both of the two ends, there is a glass window. Beneath each of the glass windows, there is an image information reading device. When an original is fed into the paper feeding end and conveyed through the first glass window, the first image information reading device starts to read the image on the first side of the original. When the original is conveyed through the U-shaped inversion device, the scanned side will be inverted to the other side.
