Zusammenfassung:A sheet conveying device (3) includes a first tray (30), a conveying portion (32), a second tray (31), and a conveyance control portion (50). The conveying portion (32) has: a first conveying path (32A) that extends from the first tray (30); a second conveying path (32B) that makes the first conveying path (32A) and the second tray (31) communicate with each other and is provided with an ejecting roller pair (328); a third conveying path (32C) that makes the second conveying path (32B) and an ejecting space (3S) communicate with each other and is provided with a reverse roller pair (329). After a first sheet (P1) passes through the reference position (X) with the second surface opposing the reference position (X), the conveyance control portion (50) stops the rotation of the ejecting roller pair (328) with a rear end side of the first sheet (P1) conveyed in the second conveying path (32B) nipped by the ejecting roller pair (328), and feeds a second sheet (P2) following the first sheet (P1) from the document feeding tray (30), with the first sheet (P1) nipped by the sheet ejecting roller pair (328), and the first sheet (P1) is already ejected onto the second tray (31) when the second sheet (P2) is in a second switchback.
