Abstract

A sheet conveying device includes a first tray, a conveying portion, a second tray, and a conveyance control portion. The conveying portion has: a first conveying path that extends from the first tray; a second conveying path that makes the first conveying path and the second tray communicate with each other and is provided with an ejecting roller pair; a third conveying path that makes the second conveying path and an ejecting space communicate with each other and is provided with a reverse roller pair. After a first sheet passes through the reference position, the conveyance control portion stops rotation of the ejecting roller pair with the first sheet conveyed in the second conveying path nipped by the sheet ejecting roller pair, and after a second sheet passes through the reference position, the conveyance control portion rotates the reverse roller pair with the rotation of the ejecting roller pair stopped.

Description

Technical field [0001] The present invention relates to a sheet conveying device for conveying sheets and an image forming apparatus equipped with the sheet conveying device. Background technique [0002] Conventionally, as a sheet conveying device that conveys a sheet, an automatic document conveying device is known. The automatic document feeder conveys the document sheet placed on the document tray to the reading position, and discharges it to the paper discharge tray. In addition, there is also known an automatic document conveying device provided with a reverse conveying path in order to read document images on both sides of a document sheet. [0003] In the automatic document feeder as described above, a part of the reverse feed path communicates with the upper side of the paper discharge tray. Therefore, the front end portion of the document sheet conveyed to the reverse conveying path pushes out the sheet discharged to the paper discharge tray, which may cause poor sheet ...
