    Abstract: A sheet conveyance unit includes a sheet inlet port, an inlet guide, and a guide switching mechanism. The inlet guide has an upper guide and a lower guide below the upper guide. The guide switching mechanism switches a position of the inlet guide between a conveyance position at which the upper guide and the lower guide face each other with a first distance and a separation position at which the upper guide and the lower guide are spaced from each other by a second distance greater than the first distance. To connect the sheet conveyance unit to the sheet discharge unit, the inlet guide is disposed to the separation position before the discharge guide is inserted between the upper guide and the lower guide, and is disposed to the conveyance position after the discharge guide is inserted between the upper guide and the lower guide.

    IPC: B65H29/52

    Abstract: The conveyance guide unit is provided with a guide member, a supporting frame, and an external cover. The guide member guides a sheet, which is discharged from a sheet discharge port of the image forming apparatus or from a sheet discharge port of a relay conveyance device installed in the image forming apparatus, to the sheet carrying-in port of a post-processing device. The supporting frame supports the guide member. The external cover is fixed to the supporting frame; the external cover covers an upper part of the guide member and side parts of the guide member in a traverse direction of a sheet conveyance path, which is perpendicular to a sheet conveyance direction. The external cover has an upper surface serving as an extension part of a discharge tray part of the post-processing device, the extension part being extended downstream, in a sheet discharge direction.

    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.

    Abstract: A control unit for controlling a document conveying operation stops the conveyance of a document by a document conveying unit if document(s) is/are placed on a placing portion, the document is being conveyed and an upper structure is not in a closing posture. Further, the control unit stops the conveyance of the document when the trailing end of the document being conveyed has not passed a document reading position and, on the other hand, causes the document to be discharged to a document discharging portion without stopping the conveyance of the document when the trailing end has passed the document reading position if no document is placed on the placing portion, the document is being conveyed and the upper structure is not in the closing posture.
