ABSTRACT:
In one embodiment of the present invention, a sheet transport apparatus is provided with a registration roller, a sheet transport path, a first optical sensor, a second sensor that detects the presence or absence of a sheet at an upstream side of the first optical sensor in a sheet transportation direction Xd, and a sheet transportation control unit that stops the driving of the registration roller after an elapse of a transportation time after the detection of sheet absence following sheet presence by the first optical sensor, wherein the sheet transportation control unit does not perform control with sheet detection by the first optical sensor within a detection restricted time after predetermined sheet detection by the second sensor when the sheet is of a specific type.
