Image reading apparatus |
摘要 |
An image reading apparatus includes a document reading and conveying unit, a pressing plate capable of moving to a position to press a document against a reading surface and to a position withdrawn from the reading surface, and a fixed reader configured to read a document fixed on the reading surface by moving a close-coupled image sensor relative to the document. The document reading and conveying unit includes a controller configured to perform pickup initialization of returning a pickup roller to an initial position after the completion of conveying one or more documents and is supported by the pressure plate. The controller includes a first timer configured to measure an elapsed time from the completion of reading performed by the fixed reader. The controller performs the pickup initialization after a measurement value measured by the first timer exceeds a first time.
