Conveying apparatus, image forming apparatus, and conveying control method

摘要

A conveying apparatus includes a first conveying unit that conveys a recording medium, a reversing unit that reverses the recording medium conveyed by the first conveying unit, a second conveying unit that conveys the recording medium from the reversing unit to the first conveying unit, and a first supply unit and a second supply unit that supply the recording medium to the second conveying unit at different supply positions. When sequentially reversing/conveying multiple sheets of the recording medium, a control unit alternately conveys the recording medium that has been reversed by the reversing unit and the recording medium that is supplied from the first or second supply unit after a predetermined number of sheets of the recording medium have been reversed by the reversing unit, and changes the predetermined number depending on whether the recording medium is supplied from the first supply unit or the second supply unit.

主权项

1. A conveying apparatus comprising:
a first conveying unit configured to convey a recording medium; a reversing unit configured to reverse the recording medium conveyed by the first conveying unit; a second conveying unit configured to convey the recording medium along a conveying path from the reversing unit to the first conveying unit; a first supply unit configured to supply the recording medium to the second conveying unit at a first supply position; a second supply unit configured to supply the recording medium to the second conveying unit at a second supply position; and a control unit configured to control the conveying apparatus, upon sequentially reversing and conveying a plurality of sheets of the recording medium, to alternately convey the recording medium reversed by the reversing unit and the recording medium that is supplied from the first supply unit or the second supply unit after a predetermined number of sheets of the recording medium have been reversed by the reversing unit; wherein the control unit is configured to change the predetermined number depending on:
whether the recording medium is supplied from the first supply unit or the recording medium is supplied from the second supply unit, andthe number of sheets of the recording medium that are to have images sequentially printed on a first side of the recording medium after the conveying apparatus has sequentially reversed and conveyed the plurality of sheets of the recording medium.
