A sheet transport path extending from a carry-in entrance to a carrying-out exit is made small and compact in an apparatus configuration provided with a path without performing the folding processing and another path to perform the folding processing in between the carry-in entrance and the carrying-out exit. The configuration is provided with a first transport path 32 for guiding a sheet from the carry-in entrance 30 to the carrying-out exit 31 without performing the folding processing, a second transport path 33 for performing the folding processing on a sheet from the carry-in entrance, and folding processing means 48 disposed in the path 33 to fold the sheet. Then, the second transport path 33 is disposed to cross the first transport path 32, and a path end portion (first switchback path 34) of the second transport path 33 for guiding the sheet to a folding position Np1 and another path end portion (second switchback path 35) for guiding the folded sheet to the downstream side from the folding position are disposed inside areas opposite each other below and under or to the left and right of the first transport path 32. In other words, when the first transport path 32 is formed of a linear path in the horizontal direction, the path 34 is disposed above the path 32, and the path 35 is disposed below the path 32.
