DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Refer to the related figures for a bill stacker detection apparatus according to a preferred embodiment of the present invention, wherein the same elements are described by the same reference numerals.
FIG. 1 is a pictorial drawing illustrating a bill stacker detection apparatus of the present invention. The bill stacker detection apparatus 1 comprises a base body 10 with a sensor 12 and a stacker 11. A conveyer (not shown) and a bill stacking mechanism (not shown) are disposed in the base body 10. The bill stacking mechanism is used to push bills into the stacker 11. The sensor 12 has a light emitting element 13 (shown in FIG. 3) and a light receiving element 14 (shown in FIG. 3).
FIG. 2 is a pictorial drawing illustrating a stacker. FIG. 3 is a pictorial drawing illustrating the relationship among a stacker, a light emitting element and a light receiving element of the present invention. As shown in FIG. 2, the casing of the stacker 11 has a protruding structure 18. Two sides of the protruding structure 18 have apertures 181 respectively. The position of the apertures 181 corresponds to the position of the sensor 12 as shown in FIG. 1. The light receiving element 14 of the sensor 12 could receive the light beam emitted by the light emitting element 13 through the apertures 181. Moreover, a plurality of prisms 31 is added to the sensor 12 according to demands so as to incorporate with the design of main mechanisms to change the path of the light beam. As shown in FIG. 3, after adding two prisms 31, the light emitting element 13 and the light receiving element 14 could be disposed at the same side. The light beam is reflected by the prisms 31 to pass through the apertures 181. The light emitting element 13 and the light receiving element 14 are electrically connected to the same circuit board to save spaces.
FIG. 4, FIG. 5, FIG. 6 and FIG. 7 are a pictorial drawing illustrating a protruding structure on the casing of a stacker of the present invention and exploded pictorial drawings illustrating a stacker of the present invention. As shown in FIG. 4, the inside of the protruding structure 18 has an accommodating room 182. A sliding block 19 is disposed in the accommodating room 182. The sliding block 19 can be moved to cover or stagger the apertures 181. Referring to FIG. 5, at least one elastic element 15 is fastened in an interior wall of the stacker 11. An end of the elastic element 15 is fastened on a bill supporting plate 16 such that the bill supporting plate 16 has displacements in the stacker 11. A side pushing block 17 of the bill supporting plate 16 is hooked with the sliding block 19 so as to enable the side pushing block 17 to push the sliding block 19.
When the sliding block 19 is in an initial position, the apertures 181 are covered. The light receiving element 14 is unable to receive the light beam because the sliding block 19 covers the apertures 181. It then determines the stacker 11 is at a predetermined position. Bills disposed to the bill supporting plate 16 are not full yet. Next, bills are continually delivered to the bill stacking mechanism (not shown) via the conveyer (not shown). The bill stacking mechanism is used again to push the bills to the bill supporting plate 16 of the stacker 11. The bill supporting plate 16 is pushed by the elastic element 15 that then leans against the bills. As the bills are continually pushed to the stacker 11, the bill supporting plate 16 is pressed by the bills to generate displacements. When the side pushing block 17 of the bill supporting plate 16 contacts with an upper portion of the sliding block 19 as shown in FIG. 7, the displacements generated by the bill supporting plate 16 push the sliding block 19. The apertures 181 are then staggered by the sliding block 19. The light receiving element 14 then receives the light beam emitted by the light emitting element 13. In another word, when enough bills are pushed to the stacker 11, the sliding block 19 is then moved to stagger the apertures 181. Accordingly, the stacker 11 filled with the bills is detected. The aforementioned way is used to determine whether or not bills stored in the stacker 11 are full by whether or not the light beam is received by the light receiving element 14.
