Abstract
A sheet transport apparatus includes a pair of rollers for transporting a sheet and a sheet detection device for detecting the sheet transported by the pair of rollers. The sheet detection device includes a flag that is displaceable when urged by the sheet transported by the pair of rollers and a single-chip acceleration sensor attached to the flag to detect the arrival of the sheet. When the sheet is brought into contact with the flag to rotate the flag, the acceleration sensor detects the roll acceleration of the flag so as to determine the timing of stopping the pair of rollers on the basis of a detection signal.
