Transport guide drive mechanism, paper sheet transport device, method for controlling paper sheet transport device, and paper sheet handling device

Abstract

The present invention provides a transport guide drive mechanism that corrects the transport state in a paper sheet transport device including a wide transport surface that can be used in common for paper sheets with different width dimensions, to a normal state while preventing a deformation or a damage of the paper sheets during continuous and unintermittent transport. The transport guide drive mechanism includes transport guidesthat are arranged along both side edges of a transport surfacein a width direction to oppose each other and that respectively guide both side edges of a paper sheet to be transported, an advancing/retreating mechanismthat causes the transport guides to synchronously protrude and retract in a predetermined direction, stopperseach of which defines a protruded position where an associated one of the transport guidesis most protruded from the transport surfaceand a retracted position retracted from the protruded position toward the transport surface, and a DC motorthat drives the advancing/retreating mechanism
