ABSTRACT:
A paper feed roller (5) is divided into a first roller (5a) and a second roller (5b); a slit (58) through which about 10 to 20 sheets of documents can pass is formed between the first roller and a gate plate (57) opposite to this; and the paper fed out therefrom is fed out to a space between the second roller (5b) and a separation pad (7) in contact with this.
Also, there is adopted a construction in which the pressing force of a paper conveyance spring is transformed by a slide cam sliding in a direction parallel to the paper feed roller; and the paper width detection sensor is assembled by a fitting construction.
