Document validating/stacking device

A document validating/stacking device comprising:

• a validator for discriminating authenticity of an inserted document and a stacker detachably attached to the validator for storing the document supplied from validator,
• wherein the validator comprises a rocker rotatably attached around a pivot shaft, a head formed with the rocker and a drive device for rotating the rocker around the pivot shaft,
• the stacker comprises an interim chamber for receiving the document supplied from the validator, a storage for receiving and holding the document supplied from the interim chamber, a pusher plate movable between an initial position within the interim chamber and an extended position within the storage, and an X-linkage having a driver arm,
• wherein the drive device comprises an actuator and a motion converter driven by the actuator for converting linear movement of the actuator into rotary movement of the rocker,
• the rotation of the rocker causes the head to move in a circular arc to separably push a passive area of the driver arm that therefore rotates in the same rotational direction as the circular arc movement of the head to expand the X-linkage, to thereby move the pusher plate from the initial position to the extended position and to stow the document within the interim chamber into the storage.
