A sheet transport apparatus for transporting a sheet along a transport path has a sheet transport mechanism having a plurality of transport rollers that transports a sheet, and a jam clearing mechanism to remove a sheet which causes a transport failure and is jammed on the transport path. The jam clearing mechanism has a coupling member coupled to a transport roller, a jam clearing dial that transfers a rotation force to the transport roller via the coupling member, and a switching device for switching so that the coupling member separates from the transport roller in transporting a sheet, while being coupled to the transport roller in clearing a jam.
