Sheet conveying device and image forming apparatus including the sheet conveying device

Abstract

The sheet conveyance device of the present invention includes a first tray, a conveyance unit, a second tray, and a conveyance control unit. The conveying section has a first conveying path, a second conveying path, a third conveying path, a fourth conveying path, a pair of discharge rollers, and a pair of reversing rollers, the first conveying path is extended from the first tray to a reference position; The second conveying path is extended from the reference position to the second tray; the third conveying path is branched from the second conveying path and communicated with the discharge space above the second tray; the fourth conveying path is branched from the third conveying path , communicating with the first conveying path; the pair of discharge rollers is arranged on the second conveying path; the pair of reversing rollers is arranged on the third conveying path. After the second surface of the first sheet faces the reference position and passes through the reference position, the conveyance control unit makes the rear end side of the first sheet fed into the second conveyance path be pinched between the pair of discharge rollers. The rotation of the pair of discharge rollers is stopped, and after the first face of the second sheet following the first sheet passes the reference position against the reference position, the pair of reverse rollers is reversed in a state where the rotation of the pair of discharge rollers is stopped. Rotate so that one end of the second sheet protrudes from the third conveyance path to the discharge space.

Description

technical field [0001] The present invention relates to a sheet conveying device for conveying a sheet, and an image forming apparatus including the sheet conveying device. Background technique [0002] Conventionally, an automatic document feeder is known as a sheet feeder that feeds a sheet. The automatic document feeder transports the document sheets loaded on the document tray to the reading position, and discharges them to the output tray. In addition, there is also known an automatic document feeder that includes a reverse conveyance path in order to read document images on both sides of a document sheet. [0003] In the automatic document feeder described above, a part of the reverse conveyance path communicates with the upper side of the discharge tray. Therefore, the front end of the document sheet conveyed to the reverse conveyance path pushes out the sheet discharged to the discharge tray, and misalignment of the sheets may sometimes occur. Contents of the inv...
