Abstract

An image reading apparatus includes an image reading unit for reading an image of a document at a reading position, a document feeding unit for discharging the document via the reading position, an abnormality detection unit for detecting a feeding abnormality, and a reading determination unit. The reading determination unit determines that the reading of the image of the fed document by the image reading unit is complete in a case where it is determined that a fed document, which is being fed by the document feeding unit, is not a final document, and it is detected that the leading edge of the fed document has reached the reading position, and when it is detected that the leading edge of the subsequent document has reached the reading position without the abnormality detection unit detecting any abnormality.

Description

technical field [0001] The present invention relates to an image reading device for reading an image of a document, and an image forming device including the image reading device, and more particularly, to a technique for judging whether scanning of an image of a document being conveyed is completed. Background technique [0002] Conventionally, an image forming apparatus including an ADF (automatic document feeder) is known. The ADF includes a conveyance unit that conveys a document placed on a document tray to a reading unit (reading position), and an openable and closable cover (openable cover) that covers the conveyance unit. When a document jam (abnormality such as a paper jam) occurs in the transport unit, the user opens the cover to remove the document. In addition, the ADF is equipped with a safety switch (opening / closing detection sensor) that detects the opening of the cover, so as to prevent the rollers of the conveyance unit from malfunctioning and causing dange...
