摘要： A sheet feeding and separting device incorporated in image forming equipment for feeding sheets one by one from a sheet stack while preventing two or more sheets from being fed together as far as possible and, when a plurality of sheets are accidentally fed together, surely separating one of them from the others. A pick-up member is implemented as an endless dielectric belt. An AC power source forms a charge pattern on the belt via an electrode. As a result, the belt retains a sheet by attraction and transports it due to the Maxwell stress generated in the sheet. When a plurality of sheets are fed together, an arresting member which faces the belt separates one of them from the others. Alternatively, a charge pattern may be formed on the surface of the arresting member.

摘要： A pair of grip rollers forming a slack in a transfer sheet by impinging the transfer sheet against a pair of registration rollers that are at a standstill, includes a one-way rotating clutch. A coil spring biases the one-way rotating clutch such that projections on a flange of the one-way rotating clutch engage with holes on a rear sideboard. When a transfer sheet caught by the pair of grip rollers is pulled out with a predetermined or greater torque in an opposite direction to that in which the transfer sheet is conveyed, the projections are disengaged with the holes, against the coil spring bias. Thereby the one-way clutch is set free and can be rotated in a reverse direction.

摘要： An image forming apparatus includes a sheet feed unit having a sheet feed port, an image forming unit, a sheet position detector, a mode selector, and a memory unit. The sheet feed unit feeds a recording sheet. The image forming unit forms an image on the recording sheet. The sheet position detector detects a sheet edge of the recording sheet. The mode selector selects at least one of the position correction mode and non-correction mode for the sheet feed port. An image forming position on the recording sheet is corrected using position information detected by the sheet position detector when the position correction mode is selected, and the image forming position on the recording sheet is not corrected when the non-correction mode is selected. A memory unit may store a plurality of values of light intensity and threshold value corresponding to different types of recording sheets.

摘要： The present invention relates to an apparatus for feeding sheets separately, the apparatus comprises a feed unit disposed over a stack of sheets for causing a conveyance force upon the uppermost of the stack thereby to feed the uppermost sheet from the stack with the conveyance force being directed in a sheet path direction. The feed unit has an alternating charged pattern on a surface thereof. The apparatus further comprises a separation unit disposed opposite to the feed unit so as to form a sheet path in association with the feed unit for causing a preventive force onto an under face of the fed sheet thereby to prevent the sheet from being fed. The preventive force is set to be less than the conveyance force and greater than a friction force between sheets. The separation unit has another alternating charged pattern on a surface thereof.
