Abstract

An image reading apparatus has an original placing portion on which an original is placed, a feed portion for feeding the original placed on the original placing portion to convey the original from one end side of an original plate onto the original plate, a conveying rotary member for conveying the original on the original plate, a reversing and conveying portion for reversing the front side and back side of the original conveyed to the other end side of the original plate by the conveying rotary member, and conveying the reversed original from the other end side onto the original plate, an image reading unit for reading the image of the original stopped on the original plate while being moved, and a control portion for controlling the driving of the conveying rotary member. The control portion controls the conveying rotary member so as to stop the original conveyed from the one end side by the feed portion at a first reading position on the original plate, and stop the original conveyed from the other end side by the reversing and conveying portion at a second reading position on the original plate differing from the first reading position.

Description

technical field [0001] The present invention relates to an image reading device and an image forming device provided with the image reading device. Background technique [0002] For example, a copier as an example of an image forming apparatus is provided with an image reading device for reading an image of a document. The image reading device is provided with an image reading section for reading an image of a document, and an automatic document feeding device for conveying the document to a designated reading position to be read. [0003] When an image of a document is to be read in such an image reading device, the document is placed on a document stacking portion of an automatic document feeder, and then the document is conveyed onto a document table. After the document has been conveyed onto the document table, the document image is read by an image reading section (see Japanese Patent Application Publication No. 2002-049188 and Japanese Patent Application Publication N...
