Abstract
A projecting tab formed with a bulged portion and an indent on an upper side thereof is provided inwardly projecting in a transport path. A sheet being transported in the transport path is formed into a seemingly wavy configuration in the width direction of the transport path while in contact with the projecting tab. The sheet thus formed with the seemingly wavy configuration is given with a sufficient transport backup force in a transport direction, thereby being hard to bend in the transport direction. Thus, the sheet supplied with the sufficient transport backup force is free from a curled lead end, folded or bent corner lead end of the sheet in the transport direction, and sheet jam. The arrangement of the projecting tab securely accomplishes sheet transport in a desired transport direction without a possibility of sheet transport failure.
