An improved image reading apparatus suitable for use with an image scanner which can read a large number of paper sheets successively and rapidly and cope with various paper sizes from a small size to a large size. The image reading apparatus includes a paper supply mechanism, a paper transport mechanism, an optical image reading mechanism for optically reading information on a paper sheet being transported by the paper transport mechanism, and a paper stacking mechanism. The paper transport mechanism includes a paper transport path including an inclined transport path and a paper reversing transport path contiguous to the inclined transport path, a plurality of paper transport rollers disposed in a spaced relationship from each other by a distance smaller than the length of a paper sheet in its transportation direction along the paper transport path, a roller driving mechanism for driving the paper transport rollers, and a roller driving mechanism control apparatus for controlling the roller driving mechanism. The optical image reading mechanism includes an optical image reading unit, and an image information extraction control apparatus for controlling extraction of image information obtained by the optical image reading unit.

Image reading apparatus having a steeply inclined paper transport path

A paper stacking apparatus for an image reading apparatus and an image reading apparatus with a paper stacking apparatus wherein paper sheets can be stacked appropriately to allow a large amount of paper sheets to be read rapidly at a time are disclosed. The paper stacking apparatus is designed to stack a paper sheet discharged from a paper transport mechanism of an image reading apparatus along which an optical image reading mechanism is disposed, and comprises a paper stacker including, at a bottom portion thereof, a stacker table for receiving thereon paper sheets discharged from the paper transport mechanism to stack the paper sheets, a paper stacker position variation mechanism for varying the position of the paper stacker, a paper discharge roller mechanism provided at a terminal end of the paper transport mechanism and having a projection extending into a paper transport path of the paper transport mechanism, and a paper trailing end guide mechanism disposed to extend into the paper stacker for guiding a trailing end of a paper sheet to be stacked into the paper stacker.
