Abstract

In an automatic document feeder, an original tray has an original platen on its upper surface. Originals put on the original platen are fed along a conveying path by conveying rollers and conveyance auxiliary rollers. The originals fed are separated one at a time by separating belts and separating rollers which are arranged above and below a conveying path. When a conveyance guide plate constituting a part of the original platen is removed upward, the separating rollers, the conveying rollers, and the conveyance auxiliary rollers and a portion for supporting the rollers are exposed upward, so that maintenance such as replacement of components such as the separating rollers, the conveying rollers and the conveyance auxiliary rollers can be performed.
