This invention relates to cash di≤pensiig apparatus and more particularly to an apparatus for dispensing a sum of money to one of a plurality of dispensing stations accessible to bank clerks and/or customers.

With the introduction of micro-processor control of cash dispensing apparatus , it is now possible to programme the software to control multiple dispensing stations and thus utilize the apparatus to its maximum. An aim of the present invention is to provide a cash dispensing apparatus which dispenses, on command, a requested sum of money to any one of at least four dispensing stations.

. According to the invention, the cash dispensing apparatus comprises: at least one feed module for storing banknotes and for delivering a selected sequence of banknotes; at least two stacking platforms, each platform having a dumping facility to dump a stack of banknotes supported on the platform; at least two dispensing stations associated with each platform; a trans er means for each plat orm to transfer banknotes

/

stacked on ^' the platform to a selected one of the dispensing stations;diverter means , and a common flow- line for banknotes leading from the feed modules to the diverter means which diverts them to a selected one of the stacking ^{^} platforms; detecting means stationed on the common flow-line for detecting the passage of multiple banknotes and for counting single banknotes; and central control means responsive to the detecting means and to commands for a delivery of banknotes to a selected dispensing station; the central control means causing the diverter means to divert single banknotes to the selected platform associated with the selected dispensing station, but to divert multiple banknotes to another platform; causing the dumping facility at that other platform to dump any multiple banknotes; and, if the detecting means indicate an incorrect total count of single banknotes, also causing the dumping facility at the said selected platform to dump the stack of single banknotes, but otherwise causing the transfer means at that selected platform to transfer the stack to the selected dispensing station.

In a preferred embodiment, the cash dispensing apparatus consists of two stacking platforms each of which has two dispensing stations, and the diverter means is a two-way device positioned in the feed-line between the two stacking platforms, the diverter means preferably comprising a solenoid-operated pivotable device.

Conveniently, each dumping facility comprises a pivotable section of the stacking platform which pivots downwards into a secure storage container positioned below the platform.

Preferably, the transfer means is in the form of a belt driven pusher plate which traverses the length of the platform between two dispensing stations.

A preferred embodiment of the cash dispensing apparatus, according to the invention, will now be described with re erence to the accompanying diagrammatic drawings in which:

Figure 1 is an end elevation, of a cash dispensing apparatus,

Figure 2 is a side elevation of the apparatus shown in Figure 1,

Figure 3 is a plan of the apparatus shown in Figures 1 and 2,

Figure 4 is an operational flow diagra . Referring now to the dxawings in detail, the cash dispensing apparatus comprises a machine housing 1 for six feed modules. Six cassettes 2 for storing banknotes of dif erent denominations are located one in each feed module and the housing is securely closed by a door 3.

Different mixes of banknotes are fed one by one from the cassettes 2, on command from the operator, along a flow path 4 to a delivery module 5. The flow path 4 passes through a device 6 for detecting multiple notes following which the flow path is divided into two directions by a diverter 7. A the ends of the divided flow paths 8 and 8' , are stacker wheels 9 and 9' which co-operate with stripper plates 10 and 10' to stack a supply of multi- denominational banknotes on respective stacker platforms A and B, one at each end of the dispensing apparatus. Each platform has a dump facility in the form of a pivotable section 11 and 11* to dump the stack of banknotes, when required, into reject compartments 12 and 12' respectively.

The stacking platforms A and B are angled to permit a neat stacking of the banknotes and each platform has a transporting means in the form of a pusher plate 13 and 13' respectively. The construction and operation of the platform and transporting .means is described in the Applicant's co-pending application No.PCT/GB81/00219. When a correct dispense is stacked on, for example, stacking platform A, the pusher plate 13 pushes the stack of banknotes to one of two dispensing stations or customer access points 14A, 14A' for removal by the customer or operator- who fed the command into the apparatus via one of the 'key-in' terminals 15A, 15A' . This arrangement thus provides a multi-station banknote dispensing apparatus the overall control of - which is effected by means of a programmed micro- processor, the sequence of operation of which is illustrated in the low diagram of Figure 4.

Whilst the diagram is generally self-explanatory, the sequence of operation will be more apparent from the following description when read in conjunction with Figure 4.

A command for a sum of money is fed into one of four key-in terminals 15A, ISA', 15B and 15B' at one of the four dispensing stations 14A- 14A' , 14B and 14B ¹ respectively. The requested sum of money is fed from the feed modules along the feed path 4 via the multiple detection device 6. The diverter 7 routes the banknotes along one or other of the paths 8 or 8 ' where they are stacked by the stacking wheels 9 or 9 ' on the platforms A or B respectively. Correctly dispensed banknotes are fed to the selected platform, i.e. the platform at the end of the apparatus f om which the command was made. The detector S also counts the single notes as they oass it.

If a multiple note, which may be a double note or even a larger number of notes stuck together or overlapping, is detected by the detector 6, it is diverted to the other platform, i.e. the one at the opposite end from that from which the command was received. A further detector (not shown) may cause notes defective in some other way, e.g. worn notes, to be diverted to the other platform. The dispensing operation continues, and. acceptable single notes are diverted to the selected platform until all the banknotes that were originally required from the feed modules have been sent to either platform. The microprocessor recognises if at least one of the notes has been rejected, and causes the rejected notes to be dumped from the other platform. It also signals for one or more replacement notes of the correct denomination to be delivered along the same path to. the selected platform. If then the total count of single notes, as detected by the detector β, is correct, the stack is delivered from the platform to the selected dispensing station, i.e.the one from which the command was received.

If, however, for some reason the count is not correct, whether a multiple note had been detected or not, the microprocessor causes the stack of notes on the selected platform to be dumped as well. The dispense is then repeated. If a dispense is dumped, then a command from another terminal .can be processed before the original aborted dispense command is repeated.

It is thus possible to utilize the apparatus to its maximum, using a central microprocessor to control all the operations. An average dispense cycle using this

apparatus takes approximately two. seconds; it would be longer if the selected platform dumped every time a multiple note was detected-
