The paper ejection tray includes an end plate 322 receiving a front end of the conveyed sheet. The end plate is arranged to be movable toward the paper refeed tray along with the received sheet. The paper refeed tray includes a refed-paper conveying means 512 for conveying the sheet on the paper refeed tray to a downstream end part in the conveying direction of the sheet on the refeed tray. The sheet on the paper ejection tray is delivered to the refed-paper conveying means by the end plate moving toward the paper refeed tray. <P>COPYRIGHT: (C)2013,JPO&INPIT |
