Problems solved by technology

[0007] Indeed, the above-mentioned conventional technique effectively copes with paper feed failure and double feed of recording paper by changing the paper size for each paper, however, in the process of feeding originals, if two or more sizes of originals are mixed in Together, the problem of the original being easily fed skewed due to the change in the contact position of the original with the pickup roller remains unsolved

Abstract

An automatic document processor for automatically conveying documents includes: a document tray; a document feed path for introducing and feeding originals from the document tray into the interior of a machine; a document pickup roller assembly for picking up originals, page by page, from the document tray; and a document drive roller for conveying originals, and is constructed such that the pickup roller assembly includes two units of document pickup rollers and a pickup roller selecting mechanism for selecting the document pickup rollers to be operated, in accordance with the document size is provided.

Description

technical field [0001] The present invention relates to a document feeding device and an image reading apparatus using the same, and more particularly to a document feeding device capable of automatically feeding a document and reading an image from a document fed by the above device image reading device. Background technique [0002] Conventionally, in an image reader used in an image forming apparatus such as a copying machine, a scanner apparatus, a facsimile machine, etc., an original document usually having a fixed size is placed on the image reader, fixed on the loading plate by an original document positioning member. position, and then transported for original image reading. In such image readers, most machines employ a configuration in which a reference position on which an original is set is formed at the center of the original with respect to a direction perpendicular to the original conveyance direction. The reason for adopting this configuration is to improve ...
