IMAGE READING DEVICE FOR READING IMAGE DATA FROM DOCUMENT SHEET, IMAGE FORMING APPARATUS, IMAGE READING METHOD

摘要

An image reading device includes a document sheet conveying portion, an imaging element, a reading processing portion, a detection processing portion, and a stop processing portion. The document sheet conveying portion sequentially conveys a plurality of document sheets placed on a document sheet placement portion. The imaging element is disposed at a document sheet conveyance path. The reading processing portion executes a reading process of reading image data from each of the document sheets placed on the document sheet placement portion. The detection processing portion detects an abnormal image from image data of a document sheet read in the reading process. The stop processing portion, when the detection processing portion has detected the abnormal image, stops the reading process and a power supply to the imaging element, and after an elapse of a predetermined wait time, resumes the power supply to the imaging element, and resumes the reading process.
