DOCUMENT DESKEWING MODULE WITH A MOVING TRACK BOTTOM AND METHODS OF OPERATING A DOCUMENT DESKEWING MODULE

摘要

A document deskewing module is provided for a self-service bunch document depositing terminal. The document deskewing module comprises a set of sensors arranged to detect when a document transported in a first direction of document travel along a document transport path is deskewed, a first set of drive rollers in the form of hard drive rollers disposed along the document transport path, a first set of idler rollers moveable towards and away from the hard drive rollers, a second set of drive rollers in the form of soft drive rollers disposed along the document transport path, a second set of idler rollers moveable towards and away from the soft drive rollers, a track bottom disposed on one side of the document transport path and movable in the first direction of document travel, and a controller arranged to (i) control operation of the first and second sets of idler rollers in response to a number of signals from the set of sensors such that a deskewed document is moved in a second direction of document travel which is transverse to the first direction of document travel, and (ii) control operation of the movable track bottom such that a leading front corner of the deskewed document is moved in the first direction of document travel when the corner moves into contact with the track bottom as the document is moving in the second direction of document travel so as to reduce tendency of the corner of the document from curling and thereby to reduce tendency of the corner from bunching up and causing a document jam condition.
