Patent number: 8041285Abstract: A paper feeding device includes a stacking plate for stacking sheets. The stacking plate is movable vertically within a range from a lower limit position to a pick-up position. The stacking plate has a first surface facing the lower limit position and a second surface facing the pick-up position. The paper feeding device also includes a driving device for driving the stacking plate. The paper feeding device has a locking member for locking the staking plate in the lower limit position. The locking member has a deformable section for contact with the second surface of the stacking plate. The deformable section becomes deformed by a driving force applied through the stacking plate as locked in the lower limit position by the driving device, to unlock the stacking plate.Type: GrantFiled: September 7, 2007Date of Patent: October 18, 2011Assignee: Sharp Kabushiki KaishaInventors: Susumu Hashimoto, Toshiki Ohgita, Hidetoshi Kaneko, Masayuki Nagatani

Patent number: 8029129Abstract: A cover support mechanism regulates an opening angle of an openable cover with respect to a chassis of an electronic device. The cover constitutes a portion of the chassis. The mechanism has a cord shaped or tape shaped stopper, and a support unit. The stopper has a first end portion and a second end portion, the first end portion being fixed to the cover. The support unit supports the second end portion of the stopper. The support unit is provided to the electronic device. The support unit has a receiving portion, a biasing member, and a braking unit. The receiving portion has a space for pulling in the second end portion of the stopper. The biasing member applies force to the stopper for pulling in the stopper into the receiving portion. The braking unit applies frictional force to the stopper when the cover is opened.Type: GrantFiled: March 14, 2007Date of Patent: October 4, 2011Assignee: Sharp Kabushiki KaishaInventors: Susumu Hashimoto, Jinichi Nagata, Hidetoshi Kaneko, Yasunobu Ohkawa

Patent number: 7780162Abstract: Rack gears of far-side paper guides are provided such that manners of meshing with pinion gears are made tighter at respective regions corresponding to locations for constraining paper of standard size, as compared to other regions. In addition, by constituting width guide plates which are upstream in a paper feed directions from far-side paper guides and width guide plates which are downstream in a paper feed directions therefrom such that respective areas of surfaces receiving paper, and respective distances from respective width guide plates to gear mesh locations, are respectively set so as to be substantially mutually equal. Impacts from stacks of paper produced during placement of paper within a paper supply apparatus may be received substantially equal at upstream and downstream from gear mesh of far-side paper guides, and torques acting on far-side paper guides upstream and downstream from gear mesh locations may be made substantially mutually equal.Type: GrantFiled: July 29, 2004Date of Patent: August 24, 2010Assignee: Sharp Kabushiki KaishaInventors: Hidetoshi Kaneko, Toshihiko Seike, Masatsugu Ohishi, Kengo Matsuyama

Patent number: 7686296Abstract: A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.Type: GrantFiled: September 19, 2005Date of Patent: March 30, 2010Assignee: Sharp Kabushiki KaishaInventors: Hidetoshi Kaneko, Masatsugu Hatanaka, Motokazu Nakao, Yoshinori Shiraishi, Hideshi Izumi, Toyokazu Mori, Yuhi Akagawa
