PROBLEM TO BE SOLVED: To provide a sheet reversing controller for rapidly switch-back reversing sheets such as mails of different length in the carrying direction. SOLUTION: A sheet reversing controller has a first conveying path 4 for conveying sheets 1 in the first direction, sensors SCO1 to detect lengths of sheets 1 in the conveying direction, a reversing unit 10 comprising a reversing roller 11 capable of performing normal/reverse rotations for taking and reversing sheets 1 supplied from the first conveying path 4 and a pinch roller 12 disposed facing the reversing roller, a second conveying path 7 for taking and conveying sheets 1 supplied in the second direction reverse to the conveying direction of the first conveying path 4 from the reversing unit 10, and a controller to control the conveyance of sheets 1. The controller controls a conveying gap between a sheet 1 and a succeeding sheet 1 on the second conveying path regardless of the length of the sheets 1 in the conveying direction.
