ABSTRACT:
A sheet transport technique of clamping and transporting a sheet by a roller and a belt abutted against the roller, the technique capable of suppressing shift of the belt in the rotation axis direction of the roller without hindering downsizing of the apparatus is provided. A sheet transport apparatus is made up of a roller101being formed with a tubular cavity having a predetermined length in a rotation direction and covered with an elastic body on the outer periphery in the rotation radius direction of the cavity and a belt unit102for abutting a belt102cof a width narrower than the width of the cavity in the rotation axis direction of the roller101against the roller face of the roller101so that it is positioned inside the range in which the cavity is formed in the rotation axis direction of the roller101,and sandwiching a sheet7between the belt102cand the roller101and transporting the sheet.
