ABSTRACT:
FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION
The present invention relates to cassettes for receiving and stacking of banknotes. In particular, the invention relates to cassettes with improved stacking capability.
Existing cassettes for banknote accepting devices such as currency validators or vending devices, include a mechanism for initially receiving a banknote in a guide with a movable actuator positioned between the guides for displacing the banknote laterally to add it to a stack of banknotes adjacent one side of the guides. Typically, this actuator moves the stack of banknotes a sufficient distance for the best banknote to clear the guides. The guides are stationary and aligned with a receiving slot of the cassette. A helical spring bias the banknote in one direction and the movement of the actuator also causes a compression of the spring.
Cassettes of this type require considerable interior space for accommodating movement of the actuator through the stationary guides for stripping of the last received banknote. Furthermore, the actuator must have sufficient power for displacing the stack of banknotes and the spring when a banknote is added to the stack. In many cases, the maximum capacity of the cassette determines the frequency that the cassettes have to be removed and large capacity cassettes are normally desired. On the other hand, space is often at a premium and there is a trade-off between the size of the cassette and the space that is available. Larger capacity cassettes have also required higher power for the actuator as the size of the stack of banknotes which is displaced is also larger.
The present invention provides a structure which more efficiently makes use of the interior volume of the cassette.
SUMMARY OF THE INVENTION
A cassette for receiving banknotes according to the present invention comprises a housing having a slot for longitudinally receiving banknotes between two opposed guides, such that the guides engage opposite sides of a received banknote. A storage arrangement is located to one side of the guides and an actuator is located at the opposite side of the guides. The actuator cooperates with the guides for engaging a banknote received in the guides and moves the received banknote into the storage arrangement. A drive arrangement is connected to the actuator and the guides for causing the guides and the actuator to move a banknote into the storage arrangement by moving the actuator through the guides in one direction as the guides are moved in the opposite direction past the actuator.
According a preferred embodiment of the invention, the drive arrangement includes a rotary cam which controls movement of both the guides and the actuator.
According to yet a further aspect of the invention, the actuator is a platform member which in a banknote receipt position closes one side of the guides and acts as a flat support for a received banknote.
According to yet a further aspect of the invention, the drive arrangement moves the guides in a direction away from the storage arrangement while moving the actuator towards the storage arrangement.
According to yet a further aspect of the invention, the storage arrangement includes a spring unit for providing a spring force urging receiving banknotes maintained in a stack against the stop and allowing movement of such stack of received banknotes to accommodate a new banknote to said stack once the actuator moves through such guides.
According to yet a further aspect of the invention, the stop for the banknote is defined by the guides and is movable with the guides.
The banknote cassette, according to the present invention, comprises a housing defining an enclosure having a slot opening wall thereof through which a banknote can be longitudinally inserted into the cassette. A banknote receiving arrangement is associated with the slot opening and comprises opposed guides in an initial position for engaging the sides of received banknote and a support member in an initial position located between and to one side of said guides. A banknote storage arrangement is located to the side of the guides opposite the initial position of the support member and receives banknotes removed from the guides. A drive arrangement is provided for moving the guides towards the initial position of the support member and for moving of the support member towards the initial position of said guides to remove a received banknote from said guides and to locate the received banknote in the storage area and thereafter return the guides and the support member back to the initial positions.
According to yet a further aspect of the invention, the cassette includes a rotating cam member which controls movement of both the support member and the guides during movement from and return to the initial position.
According to yet a further aspect of the invention, the guides members and the support member each have their own linkage with a cam follow arrangement attached to said cam member with said linkages maintaining said guides and said support arrangement in a generally parallel relationship during movement of the support member through the guides.
