Abstract
An automatic document feeder (ADF) with a feeding roller used to carry a paper sheet to a reading position is provided. The ADF comprises a feeding path, a paper cartridge, an exit roller set, and a first lever. The feeding path is arranged in the ADF for guiding the paper sheet reaching the reading position and leaving the reading position. The paper cartridge has a fixed front edge aligned with an inlet of the feeding path. The exit roller set is located by the feeding path and at a downstream position with respect to the reading position. The exit roller set includes two exit rollers leaning against each other for carrying the paper sheet leaving the ADF. The first lever is connected between the paper cartridge and one of the exit rollers. As the paper sheet is jammed at the exit roller set, the paper cartridge may be raised to drive the first lever to separate the two exit rollers for removing the jammed paper sheet.
