ABSTRACT:
A paper feeder includes a paper feeder main body arranged above a rectangular, parallelepiped stack of sheets. A support mechanism for supporting the main body above the stack is provided on the paper feeder main body. A feed roller is supported by the paper feeder main body and in contact with the uppermost sheet to feed the uppermost sheet in a predetermined direction. Metal pawls for allowing movement of the uppermost sheet and preventing movement of the other sheets are likewise supported by the paper feeder main body. The mechanism moves downward together with the paper feeder main body in accordance with a change in the height of the stack upon sheet feed, thereby supporting the paper feeder main body and metal pawls at a predetermined position with respect to the uppermost sheet.
