A sheet transport apparatus that transports a sheet to a reading section for reading the sheet, has a reading front roller pair contacting with a front end of the sheet to form a register loop in the sheet; a first transport path extending curvingly toward the reading front roller pair; a second transport path extending curvingly toward the reading front roller pair after joining the first transport path; a first register space in which a register loop is formed in a sheet guided along the first transport path; and a second register space in which a register loop is formed in a sheet guided along the second transport path. The first register space is provided on the upstream side of a junction position in which the first transport path joins the second transport path, and the second register space is provided on the downstream side of the junction position.

Sheet transport apparatus

A sheet transport apparatus for transporting a sheet along a transport path has a sheet transport mechanism having a plurality of transport rollers for transporting a sheet; and a jam clearing mechanism for removing the sheet, when the sheet causes a transport failure and is jammed on the transport path. The jam clearing mechanism has a coupling member coupled to a transport roller, a jam clearing dial that transfers a rotation force to the transport roller through the coupling member, and a switching device for switching so that the coupling member separates from the transport roller in transporting a sheet, while being coupled to the transport roller in clearing a jam.

Tray means for stacking sheets, pickup means for separating and for conveying sheets into a single sheet on the tray means, and sheet conveyance means for conveying a sheet separated by the pickup means to a predetermined processing position are provided. Projecting guide means project from a sheet support surface of the tray means into a notched opening of the sheet is provided; and an oblique surface is formed to prevent a trailing side edge of the opening from catching on a leading side edge of the opening of a lower sheet when feeding an uppermost sheet to the projecting guide means. This makes it possible to feed only the uppermost sheet downstream without an opening edge formed in the uppermost sheet from interfering with an opening edge of a lower sheet.
