The present invention relates to a document feeder, document feed method, and image capture device. The document feeder includes a sheet separation mechanism that restricts the number of sheets to be fed by a pull-in portion. The sheet separation mechanism includes a first separation portion that contacts the sheet, and moves so as to feed the sheet, a second separation portion, located opposite to the first separation portion, which defines a part of a sheet feed path between the second and first separation portions, and moves so as to allow the sheet to be fed, and a brake portion that variably applies to the second separation portion a load allowing the second separation portion to move.

Document feeder, document feed method, and image capture device

A sheet separator to separate sheets of documents supplied as a stack into a single sheet. The sheet separator has a first separating mechanism and a second separating mechanism, each of which has a separating roller. The second separating mechanism is provided at a position downstream from the first separating mechanism. The peripheral velocity of the second separating roller may be set lower than a peripheral velocity of the first separating roller.

Document sheet separator and optical document reader

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.
