| 20110042885 | Media Friction Buckler Assembly - A tuned media buckler comprises a body made of a plastic material, a rib extending from the upper surface of the body with an overall flat configuration and uniform rigidity with the rib running along the upper surface and centrally lengthwise along the body, a spring force material backing the lower surface of the body opposite to the rib that compresses against the lower surface of the body in response to the generally normal force applied to the top edge surface of the rib by a media stack, and a housing having a central aperture running lengthwise of the housing such that the rib of the media buckler extends through the aperture for engagement by a media stack. | 02-24-2011 |
| 20130020754 | Slidable Sheet Separator for an Image Forming Device - A sheet separator and apparatus utilizing the same for separating media sheets in an image forming device. The apparatus includes a supporting member for supporting a stack of media sheets, a pick assembly to pick media sheets and to feed the media sheets to a processing assembly of the image forming device, and a media dam having at least one sheet separator. Each sheet separator includes a casing inclined at a predetermined angle to the supporting member, a biasing member and a base member slidable within the casing. A plurality of detents in the form of steps or teeth are provided on a sheet receiving surface of the base member and the biasing member act to separate a top most media sheet from an adjacent media sheet to prevent double feeding of media sheets. | 01-24-2013 |
| 20150108708 | Paper Separating Device and Image Forming Apparatus - A paper separating device for separating a paper sheet includes a frame member, an image carrier, a securing plate, and two types of assemblies. The two types of assemblies include: a first assembly that includes a separation claw configured to separate the paper sheet from the image carrier, a guiding member configured to guide the paper sheet, and a holder with an engaging portion; and a second assembly that engages the guiding member alone to the holder with the engaging portion without holding the separation claw. The frame member and the securing plate each include an assembly securing portion with an engaged portion to be engaged with the engaging portion of the holder. One of the two types of assemblies is secured to the assembly securing portion disposed at the securing plate while another is secured to the assembly securing portion disposed at the frame member. | 04-23-2015 |
| 20160052734 | SHEET TAKEOUT AND SEPARATION DEVICE AND SHEET PROCESSING APPARATUS - A sheet takeout and separation device has a takeout section, a sending section, a separation portion. The takeout section takes out a sheet. The sending section sends out the sheet taken out by the takeout section. The separation portion is provided so as to come in contact with the sheets taken out in an overlapping state by the takeout section, and separates the sheets one by one. In addition, the separation portion has a separation portion main body and a cover. The separation portion main body elastically deforms in accordance with a thickness of the sheet. The cover is provided on the separation portion main body so as to come in contact with the sheet. And, on a surface of the cover, a surface roughening treatment for enhancing a friction coefficient of the relevant surface is performed. | 02-25-2016 |

| 20090309293 | SHEET FEEDING DEVICE - A sheet feeding device includes a pick roller and a resilient element disposed above the pick roller. The pick roller has a roller surface. The resilient element includes two side resilient arms and a center resilient arm located between the two side resilient arms. Free ends of the two side resilient arms are pushed forward by all sheets when the sheets arrive between the free ends of the two side resilient arms and the roller surface. A free end of the center resilient arm faces the roller surface of the pick roller and maintains a gap therebetween. When too many pieces of paper are drawn forward to the resilient element, the side resilient arms are pushed forward further more, the uppermost paper contacts the center resilient arm. The center resilient arm cooperates with the side resilient arms to provide the paper a pressure big enough to be conveyed forward. | 12-17-2009 |
