Problems solved by technology

These large diameter compression springs have proven to be quite acceptable for small capacity cassettes but this type of design has not proven effective with large capacity cassettes for example, banknote cassettes capable of receiving of 1,500 banknotes or more.
In this case, the springs are longer in length and require considerable space.
This longer size reduces the capacity of the cassette.
Furthermore, because of the larger capacity of the cassette the stroke distance that the pressure plate moves within the cassette from an empty condition to a full condition is much larger and a considerable pressure differential between the empty condition and the full condition may occur.
These large diameter wound springs can also undergo considerable sag due to there own weight for large stroke distances and this sag can also reduce the effective operation of the cassette.

Embodiment Construction

[0022]FIG. 1 shows a horizontal sectional view through a banknote cassette 2. FIGS. 2 and 3 show vertical sections through the banknote cassette with FIG. 3 showing an extended position of a stacking mechanism 12 used to add a banknote to the stack of banknotes 24 and FIG. 2 showing a vertical section of that.

[0023] For large capacity banknote cassettes the actual storage section 14 can be quite large and this has presented problems with respect to the controlled movement of the spring bias pressure plate 16. Various arrangements have been provided for loosely maintaining the generally vertical orientation of the pressure plate 16 for sympathetic movement as the stacking mechanism 12 moves between the extended position of FIGS. 2 and 3 and the initial retracted position of FIG. 1.

[0024] In a banknote validator an accepted banknote is provided to the banknote cassette and enters the initial receiving section 10 through the banknote receiving slot 8. Opposed guide members 40 and 42 ...

Abstract

A banknote cassette includes a container having a spring biased pressure plate for maintaining a stack of received banknotes. A cable retraction mechanism exerts the bias force on the pressure plate and allows the displacement of the stack of banknotes when a banknote is added to the stack. Preferably, a helically wound spring cooperates with a cable reel to wind and unwind the cable as necessary and to maintain a tension force in said cable.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a banknote cassette and in particular relates to a compact spring bias arrangement used for providing a spring bias maintaining a stack of banknotes. BACKGROUND OF THE INVENTION [0002] Banknote cassettes are received in a banknote acceptor and provide a storage container for receiving accepted banknotes. From time to time these banknote cassettes are removed from the banknote acceptor and a new empty cassette is inserted. Typically, the banknote cassettes include a lock mechanism to prevent unauthorized entry to the container. [0003] For many applications it is desirable to maintain accepted banknotes in a stacked manner within the banknote cassette and the cassette is provided with a banknote receiving section for initially receiving an accepted banknote and a stacker mechanism within the cassette displaces the received banknote from the initial receiving section to a storage section. The accepted banknote, as it is mov...
