Abstract

PURPOSE:To eliminate the need to reset documents by regarding properly set documents as a non-jammed state even if they are opened and closed as they are when the operation is in a stand-by state after a copying action is interrupted and making it possible to restart in that state. CONSTITUTION:If the presence of documents is detected when conveyance is restarted after a copying action has been interrupted, documents are fed in a pre-feed position 51, whereas if the absence of documents is detected, a pair of feed rollers 49 is driven during a prescribed period. Afterwards, whether documents exist in the pre-feed position is again detected. If the absence of documents is detected, feeding documents from a paper feed tray 44 is selected, whereas if the presence of documents is detected, feeding documents from the pre-feed position 51 is selected. If documents are properly set to the pre-feed position 51 or the paper feed tray 44 in the stand-by state after a copying action is interrupted, they are not regarded as being jammed even if a conveying part 43 and an inverting part cover 62 are opened and closed with documents set in such a manner. Conveying documents can continue (conveying can restart) in that state even if a copying action is resumed. Thus resetting documents to the paper feed tray 44 is obviated.
