Bill Stacker Detection Apparatus

Abstract

A bill stacker detection apparatus comprises a base body, a stacker and a sensor. The sensor has a light emitting element and a light receiving element. When the stacker is moved to a position near the sensor, apertures of a protruding structure on the stacker is covered. The light receiving element is unable to receive a light beam emitted by the light emitting element. If bills fill with the stacker, a bill supporting plate then pushes a sliding block. The aperture is staggered by the sliding block. The light receiving element then receives the light beam to detect whether the stacker is disposed on the base or filled with bills.

1 . A bill stacker detection apparatus comprising:
 a base body having a sensor, said sensor having a light emitting module and a light receiving module; and   a stacker, an elastic element being fastened on an interior wall of said stacker, an end of said elastic element being fastened on a bill supporting plate that enables said bill supporting plate to have displacements in said stacker, the casing of said stacker having a protruding structure, the inside of said protruding structure having an accommodating room, two sides of said protruding structure having apertures corresponding to the position of said sensor so as to enable said light receiving module to receive the light beam emitted by said light emitting module through said apertures;   a sliding block disposed in said accommodating room, said sliding block being blocked by a side pushing block of said bill supporting plate to cover or stagger said apertures so as to detect whether or not said stacker is mounted to said base body, or bills stored in said stacker are full by detecting whether or not the light beam emitted by said light emitting module is received by said light receiving module.   
   
   
       2 . The bill stacker detection apparatus of  claim 1 , wherein said sensor further comprises a plurality of prisms. 
   
   
       3 . The bill stacker detection apparatus of  claim 1 , wherein said elastic element is a spring. 
   
   
       4 . The bill stacker detection apparatus of  claim 1 , wherein said base body further comprises a rail so as to provide said bill acceptor to move on said rail. 
   
   
       5 . The bill stacker detection apparatus of  claim 1 , further comprising a control device, wherein when said stacker filled with bills is detected, said control device then requires said stacker to be removed from said base body, and another said stacker with fewer bills is therefore allowed by said control device to be moved into said base body.
