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.
An image reading apparatus having a paper guide mechanism in which one pair of paper guides (301a, 301b) provided on a paper stand or both sides of a paper passage are connected via a first symmetrical movement mechanism (304) symmetrically around the center thereof for synchronous and free movement of the guides and for sheets of paper having different widths to always be guided with the center as the reference, characterized in that locking releasing pieces (306a, 306b), biased in one direction by springs (307, 326), are provided in the paper guides, said locking releasing pieces being connected by a second symmetrical movement mechanism (314) for independent movement with respect to said first symmetrical movement mechanism (304), and said second symmetrical movement mechanism and locking releasing pieces being connected by a locking mechanism (317).
