***WITHDRAWN PATENT AS PER THE LATEST USPTO WITHDRAWN LIST***Sheet feeding apparatus and image forming apparatus

Tue, 05 May 2015 08:00:00 EDT

A sheet feeding roller 101 which feeds a sheet S stacked on a sheet supporting plate 110 capable of being lifted and lowered is swingably supported at a swing end of a sheet feeding roller supporting arm 104 which is arranged swingably in an up-and-down direction and a roller biasing member applies a force to the sheet feeding roller supporting arm in a direction that the sheet feeding roller is pressed to sheets S stacked on a sheet stack tray. A swing fulcrum 104a is arranged in a range between a tangential line of the sheet feeding roller at the upstreammost pressing position against the sheet feeding direction and a tangential line of the sheet feeding roller at the downstreammost pressing position out of pressing positions where the sheet feeding roller is pressed to the sheets as being varied in accordance with a sheet stacking state of the sheets.



Paper feeding device and image forming apparatus

Tue, 05 May 2015 08:00:00 EDT

In the present invention, when a status of clogging a paper due to some cause occurs, controls of inverting a conveyance roller and returning the jammed paper in a paper feeding tray is performed. At this time, the position of a paper damming up member is lowered by an actuator when the jammed paper is returned to the paper feeding tray and the conveyance roller is inverted so as to avoid a state in which the paper damming up member 33 hinders the returning of the paper and the paper cannot be returned to the paper feeding tray. The paper damming up member is lowered to a position that is lower than a conveyance guide plate at a downstream side in a paper conveying direction. Then, the paper is returned to the paper feeding tray without damage. The returned paper can be reused.



Sheet conveyance device, document conveyance device, and image forming apparatus

Tue, 05 May 2015 08:00:00 EDT

In a sheet conveyance device, if a sheet has not been detected at a second position when a predetermined time has elapsed since the sheet has been detected at a first position, a separating portion switches operation thereof from a separating operation to a non-separating operation of conveying the sheet from upstream to downstream in a sheet conveyance path, and a sheet feed portion continues a feeding operation. If the sheet has not been detected at the second position by the time a predetermined time has elapsed since the separating portion has started the non-separating operation, the separating portion and the sheet feed portion stop driving, and if the sheet has been detected at the second position by the time, the separating portion switches operation thereof from the non-separating operation to the separating operation, and the sheet feed portion continues the feeding operation.



Sheet processing apparatus

Tue, 05 May 2015 08:00:00 EDT

A sheet processing apparatus includes a sheet conveying path; a sheet entrance unit provided in the sheet conveying path; a sheet discharge unit provided in a location separated from the sheet entrance unit by a predetermined distance; a driving unit that drives the sheet entrance unit and the sheet discharge unit; a sheet guide unit that guides sheets and is provided between the sheet entrance unit and the sheet discharge unit to allow the sheets passing through the sheet entrance unit to be sequentially stacked; and a sheet buffer device that is configured such that the stacked sheets pass through the sheet discharge unit while the stacked sheets are loaded on a step with each leading end of the stacked sheets being separated with a predetermined interval.



Facility wide mixed mail sorting and/or sequencing system and components and methods thereof

Tue, 28 Apr 2015 08:00:00 EDT

The invention generally relates to a facility wide sorting and/or sequencing system for improving product processing operations and, more particularly, to a facility wide system and related functionality for simultaneously sorting and sequencing mixed mail pieces such as, for example, flats and letter mail pieces. The flats and letter mail pieces are placed in frames so that all types of mail pieces can be sorted and/or sequenced simultaneously through merging and diverting a stream of filled trays into and out of different streams at a full or substantially full transport speed.



Electronic device and peripheral element ejecting method thereof

Tue, 28 Apr 2015 08:00:00 EDT

An electronic device capable of ejecting a peripheral element is disclosed, including a housing, a first wheel and a driving unit. The housing has a chamber, wherein the peripheral element is stored in the chamber. The first wheel is disposed in the housing, wherein the first wheel contacts the peripheral element. The driving unit is disposed in the housing, the driving unit rotates the first wheel, and the first wheel moves the peripheral element from a first position to a second position.
