Abstract
A sheet transport apparatus includes the first transport rollers, the second transport rollers arranged at downstream of the first transport rollers to receive a sheet transported from the first transport rollers, a spacing device for setting the first transport rollers to a sheet nipping state or a sheet released state, a sheet detection device for detecting a sheet length in a transport direction, and a comparing device for comparing the sheet length detected by the sheet detection device with a predetermined length. It is controlled such that the spacing device is activated to switch the first transport rollers from a sheet nipping state to a sheet released state after the sheet is transported by a predetermined distance when the sheet length is longer than the predetermined length, and to maintain the first transport rollers in the sheet nipping state when the sheet length is shorter than the predetermined length.
