To provide a sheet carrying device capable of connecting the same sheet processor to a plurality of printers with sheet discharge ports different in position.

For a sheet carrying device 2 in which a printer 1 is connected to a sheet processor 3 including a bookbinder, a carrying mechanism having a first and a second carrying rollers 18, 19 and a first and a second guide plates 20, 21 and holding rollers 2b, 2c are used to carry sheets from the printer 1 to the sheet processor 3. In case where the printer with a sheet discharge port different in position is used, a levelling handle 6 is operated to rotationally move a supporting frame 10 supporting the carrying mechanism around a supporting pin 7 for fitting the position of the first guide plate 20 to the position of the sheet discharge port 1a of the printer. If paper jam occurs, a cover 4 rotationally moved around the supporting pin 7 to open the carrying mechanism for removing the sheets.
