PURPOSE: A roller clearance control unit of a paper money discriminating part for cash dispenser is provided to prevent a damage due to the frictional force by controlling a clearance between a contra roller and a feed roller according to the thickness of paper money. CONSTITUTION: A paper money discriminating part for cash dispenser includes a pickup roller, a feed roller(6), and a contra roller(7). The pickup roller is installed at the inside of the cash dispenser module in which a cash box is installed. The feed roller is installed at a lower side of the pickup roller. The contra roller and the feed roller face each other. The contra roller is eccentrically installed to form an eccentric portion for a contra roller axis(12). A roller axis rotation portion is installed to control a clearance between the contra roller and the feed roller. The roller axis rotation portion includes a driven gear(111), a driving gear(112), a step motor(115), and a rotation restriction portion. The driven gear is fixed to an end portion of the controller axis. The driving gear is coupled to the drive gear. A shaft of the step motor is connected to a shaft fixed to a center of the driving gear. The rotation restriction portion restricts the rotation when the driving gear is not operated. |
