SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS

摘要

A sheet conveyance apparatus conveys a sheet without imposing a load on a drive unit due to the bend of the sheet when the sheet is conveyed from one unit to the other, and when the sheet is conveyed by a second conveyance unit and a first conveyance unit, a first control unit controls a first drive motor and a second control unit controls a second drive motor to make a sheet conveyance speed of the first conveyance unit equal to or higher than that of the second conveyance unit.

1. A sheet conveyance apparatus comprising a first unit and a second unit attachable to the first unit,
the first unit including: a first conveyance unit configured to convey a sheet; a first drive unit configured to drive the first conveyance unit; a first detection unit provided in the vicinity of the first conveyance unit and configured to detect the sheet; and a first control unit configured to control the drive of the first drive unit so that a sheet conveyance speed of the first conveyance unit changes based on a result of detection by the first detection unit; and
the second unit including:a second conveyance unit provided upstream of the first conveyance unit and configured to convey the sheet;a second drive unit configured to drive the second conveyance unit;a second detection unit provided in the vicinity of the second conveyance unit and configured to detect the sheet; anda second control unit configured to control the drive of the second drive unit so that a sheet conveyance speed of the second conveyance unit changes based on a result of detection by the second detection unit;wherein, when the sheet is conveyed by the second and first conveyance units, the first control unit controls the first drive unit and the second control unit controls the second drive unit so that a sheet conveyance speed of the first conveyance unit becomes equal to or higher than that of the second conveyance unit.
