  • Patent number: 9906662
    Abstract: A scanning device includes an upper cover, and a separation module detachably and changeably assembled in the upper cover. A middle of a bottom surface of the upper cover is recessed in an upward direction to form an assembling groove. The separation module includes a fastening holder, a separation roller assembly received in the fastening holder, a torsion limiter and a sealing cover. The torsion limiter is engaged with the separation holder. The sealing cover is mounted under the fastening holder. Different separation modules detachably and changeably assembled in the assembling groove are capable of being equipped with different torsion limiters. When the scanning device scans papers of which grams are different, torsion values of the scanning device are capable of being adjusted by virtue of changing the different separation modules equipped with the different torsion limiters.

    Abstract: To easily replace a retard roller (that is a media separation roller) while minimizing the required installation space, a printer 1 has a first media conveyance path 12 that conveys sheet media; a second media conveyance path 29 that conveys media and can open and close; a media conveyance roller 17 and a retard roller 16 disposed opposite each other with the first media conveyance path 12 therebetween; and a roller installation unit 70 to which the retard roller 16 is installed removably from the second media conveyance path 29 side. The retard roller 16 can be easily replaced from the open second media conveyance path 29. Compared with a configuration having a dedicated opening, a smaller opening and space for replacing the media separation roller are required.

  • Patent number: 8944431
    Abstract: A media inverting system is described for a cut sheet printing system. A first media transport advances a media sheet in a first direction, the media sheet having a first side that contacts the first media transport and an opposing second side. A rotatable member having a rotation axis that is substantially parallel to the first direction receives the media sheet from the first media transport and rotates to advance the media sheet around the rotatable member. A rotatable member force mechanism is switchable between a first state where the second side of the media sheet is held to the rotatable member, and a second state where the media sheet is released. A second media transport receives the media sheet from the rotatable member and advances the media sheet in an inverted orientation in a second direction that is substantially parallel to the first direction.

  • Publication number: 20150014915
    Abstract: An image forming apparatus which enables double-sided image formation using a sheet feeding unit, and is capable of discharging a sheet, whose sheet length is undetermined by the time the sheet reaches a branch area in conveyance for double-sided image formation, without guiding it to a sheet inverting unit. A conveying flapper switches a destination for a sheet to a first conveying path leading to a sheet inverting unit or a second conveying path leading to a sheet discharge tray. A length of a sheet in a conveying direction is detected while the sheet is being conveyed. When a size of the sheet is undetermined, and the length of the sheet is not detected by the time the sheet reaches the conveying flapper, the conveying flapper is controlled so as to convey the sheet with an image formed on a first side thereof to the second conveying path.

  • Patent number: 8925918
    Abstract: A conveying apparatus has a first conveying roller pair; a second conveying roller pair; a first conveying path through which a sheet is conveyed in such a manner that the first conveying roller pair is placed downstream of the second conveying roller pair; and a second conveying path through which the sheet is conveyed in such a manner that the first conveying roller pair is placed upstream of the second conveying roller path. A circumferential velocity of at least one of the first conveying roller pair and the second conveying roller pair is switched so as to meet conditions, i.e., |Va|>|Vb| when the sheet is conveyed through the first conveying path and |Va|?|Vb| when the sheet is conveyed through the second conveying path. Here, |Va| is an absolute value of the circumferential velocity of the first conveying roller pair, and |Vb| is an absolute value of the circumferential velocity of the second conveying roller pair.

  • Patent number: 8919761
    Abstract: The present invention provides a sheet conveying device comprising a first conveyance path for conveying a sheet from a pair of first rollers to a pair of second rollers, a second conveyance path for performing switchback conveyance of the sheet, a switching unit for switching the second rollers between a press-contacted state and a separated state, and a single driving source for driving the rollers and the switching unit. A non transferring of drive section is set where when the driving source switches the rotation direction after the sheet that has been switchback-conveyed has reached the first rollers, a drive from the driving source is not transferred to the second rollers. The switching unit is driven to separate the second rollers during a time the drive is not transferred to the second rollers due to the non transferring of drive section.
