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 document width detection sensor detecting the width dimension of the supplied paper (1) while coming into contact with the paper, characterized in that said document width detection sensor has a sensor arm (124) having a detection lever (135) rocking when abutting against the paper and a sensor bracket (123) which supports said sensor arm (124) so that it can freely swing;
