ABSTRACT:
An automatic feeding device for feeding plural number of recording sheets stacked on a pressure plate by separating them one by one is provided with a sheet-feeding roller for carrying the recording sheets stacked on the pressure plate; a separation roller for separating the recording sheets one by one by abutting against the recording sheet carried by the sheet-feeding roller; and a fornt stage-regulator that confines the number of recording sheets advancing into the separation roller. At least one of the sheet-feeding shafts provided for both ends of the sheet-feeding roller is made movable along the bearing groove of elongated hole of the bearing, and least one of the sheet-feeding shafts is structured to move between plural positions during the execution of a series of feeding operations. With the structure thus arranged, it is made possible to enable the recording medium to be bitten stably into the nipping portion of the sheet-conveying roller and pinch roller in good condition.
