PURPOSE: To provide the mechanism of surely sending out the bundle of paper money varying its thickness even at the time of using in a long period and surely capturing them the exit of a cash dispenser in a mechanism used for piling and representing in common, which is used for paper memory in a cash dispenser, etc.

CONSTITUTION: A cash paying unit includes first and second cooperation endless belts 72 and 74 for sending the bundle 76 of the paper money to an output port 54. The tip parts of the first and second bolts respectively pass around first and second pulleys 52 and 66. The first pulley 52 is provided with a fixed rotary shaft line. The second pulley is rotatably mounted to one tip of a rotatably mounted arm 56 and a third puller 64 is rotatably mounted at the other tip of the arm 56. The third pulley 64 is engaged to a part of the second endless belt 74 cooperatively engaged with the first belt 72. As the first and second belts 72 and 74 are elastically extendable and stretched, when the bundle 76 is positioned at the output port 54, the first and second pulleys 52 and 66 are energized so as to capture the bundle in between the first and second belts 72 and 74.
