摘要： A sheet is fed to a registration roller pair by a separation-feeding unit formed by a sheet feeding roller and a separation portion, and is caused to abut a nip portion of the registration roller pair at rest to form a loop in the sheet. Then, when the registration roller pair rotates at a predetermined timing to convey the sheet, a pressurization plate is raised again to bring the sheet into press contact with the sheet feeding roller to thereby impart a conveyance force to the sheet, making it possible to feed the sheet reliably to the registration roller pair.

摘要： A sheet feeding apparatus includes a sheet stacking unit, a suction conveyance unit configured to convey an uppermost sheet stacked on the sheet stacking unit, a suction unit configured to adsorb the sheets onto the suction conveyance unit, and an adsorption completion detection unit. In the sheet feeding apparatus, when the tab-attached sheets are stacked on the sheet stacking unit and fed such that their tab portions are on the downstream side in a sheet feeding direction, the suction unit starts to adsorb the sheet in response to a sheet feeding signal, and the suction conveyance unit starts to convey the sheet immediately after the adsorption completion detection unit detects the completion of the adsorption. When the sheets other than the tab-attached sheets are fed, the suction unit previously adsorbs the sheet onto the suction conveyance unit, and the suction conveyance unit starts to convey the sheet in response to the sheet feeding signal.

摘要： Provided is a sheet feeding device having a sheet surface detecting mechanism installed to be movable up and down between adjacent adsorption conveyance belts 21, and detects a position of the top surface of the sheet by a sheet surface detecting member 61 that moves upward higher than the adsorbing surface of an adsorption conveyance belt 21. The position of the lower surface of the sheet surface detecting member 61 being pushed up by the blown-up sheet is regulated such that the difference in height between the adsorbing surface of the adsorption conveyance belt 21 and the lower surface of the sheet surface detecting member 61 is smaller than the difference in a height direction between the adsorbing surface of the adsorption conveyance belt 21 and the upper surface of a separation nozzle by a sensor abutting portion 62 that regulates upward movement of the sheet surface detecting member 61.
