AUTO-DOCUMENT FEEDER AND AUTO-DOCUMENT FEEDING METHOD

摘要

An auto-document feeder includes plural conveying sections which have different paths to reach an image scanning section configured to scan an image on a document from a paper feeding section and which guide the document to the image scanning section, a scanning conveying section configured to alternately nip the documents one by one fed by the plural conveying sections and feed the documents in a direction of a paper discharge section through the image scanning section, a gate section which directs the documents to one of the plural conveying sections, and a detecting section configured to detect if a document is fed by the paper feeding section.
