A first conveying mechanism conveys a sheet. A correction member is provided more on an upstream side of a conveying direction of the sheet than the first conveying mechanism, and includes a contact surface that comes into contact with a side end of the sheet at one end of a conveying path of the sheet in a width direction. A first orientation adjustment mechanism is operated by being input with a drive signal and changes an angle of the contact surface. A second conveying mechanism is provided more on the upstream side of the conveying direction than the correction member, and conveys the sheet toward the contact surface along a direction oblique with respect to the conveying direction. A support member supports the correction member and the first orientation adjustment mechanism. A second orientation adjustment mechanism is capable of changing an orientation of the support member by being operated manually.
