Abstract
A processing apparatus processing on a sheet includes a punch unit configured to punch a sheet at a punching position while rotating, a first motor configured to drive the punch unit, a first rotary member disposed upstream of the punch unit in a conveyance direction of the sheet and configured to convey the sheet, a second motor configured to drive the first rotary member, a control unit configured to control driving of the first motor and the second motor, and a first detection unit configured to detect a surface speed of the first rotary member. The control unit is configured to adjust a rotation speed of the second motor so that a surface speed of the first rotary member obtained based on a detection result of the first detection unit substantially matches a tangential component of a rotation speed of the punch unit at the punching position.
