Cash Transaction Machine and Method With Money Disinfection

The present invention relates to the cash transaction machine, and a more particularly to cash transaction machine and method for receiving cash (bills and coins) thrown in by a user of an automatic teller machine, an automatic charge paying machine or an automatic vending machine, transacting it by user's manipulation and redispensing cash as required.

In an automatic teller machine shown in JP-A-62-42296, the machine receives cash (bills and coins) thrown in by a user, transacts (receives) it by the user's manipulation and stores it in a bill storage box. It also transacts (pays) cash by the user's manipulation, takes bills out of the bill storage box and dispenses them to the user. In an automatic vending machine or an automatic ticketing machine, it receives cash thrown in by a user, transacts (dispenses commodities or issues a tcket) by th user's manipulation, and dispenses change as required. In those machines, the cash thrown in by the users are discharged as dispensing cash or change. Accordingly, dirty bills or coins may be included in the dispensed cash.

Money is transferred from many sources of people to other people and it is sometimes desired to clear the dirty money for the users or the manager of the machine. JP-A-47-45997, JP-A-49-24194 and JP-A-63-66059 disclose machines which sterilize and disinfect bills, but those are exclusively used for the sterilization and disinfection. Thus, in order to sterilize and disinfect the bills, the manager of the machine must handle the dirty bills and put them into the machine. Accordingly, it is not possible to automatically sterilize and disinfect the money without intervention of the manager in a machine such as the cash transaction machine which receives the cash thrown in by the user, transacts it by the user's manipulation, and redischarges the thrown-in cash as dispensing money or change.

It is an object of the present invention to provide cash transaction machine and method which has a money disinfection function.

It is another object of the present invention to impart a good impression to users and a manager of a cash transaction machine by disinfecting moneys received and paid in the transaction in order to maintain the money in good sanitary condition.

One embodiment of the present invention is now explained in detail with reference to the drawings.

FIG. 1 shows an automatic teller machine in accordance with one embodiment of the present invention. The bills thrown in from a receptacle 1 are separated one by one by a separation unit 2-1 and they are transported to a discrimination unit 4 by a transport unit 3. The discrimination the unit 4 discriminates denomination, genuineness, the damage and the number of sheets. They are further transported by a transport unit 5 and stored in a temporary store unit 6. If the transaction manipulated by a user is met, the bills are separated by a separation unit 2-2, transported by a transport unit 7 to the discrimination unit 4 for discrimination, and transported to and stored in denomination boxes 9-1, 9-2 and 9-3 which store the bill by denomination, through transport units 8 and 3. This is the money receiving transaction.

In the money paying transaction, the required numbers of sheets of bills are separated from the denomination boxes 9-1, 9-2 and 9-3 by a separation unit 2-9, they are stacked in the receptacle 1 and dispensed.

In the present embodiment of the automatic teller machine, the receptacle 1 is shared by a money receiving port and a money paying port, although a coin throw-in port and a charge port may be separated as they are in an automatic ticketing machine.

When the bills residing in the denomination boxes 9-1, 9-2 and 9-3 become small because the money paying transaction is larger than the money receiving transaction, bills are loaded in a removable/insertable bill cassette 11; a separator 12 is retracted to a broken line position 12', and the bills in the cassette 11 are removed by the temporary store unit 6. The bills are transported to the discrimination unit 4 through the transport unit 7; the discrimination unit 4 discriminates the denomination and the numbers of sheets of the bills, and the bills are stored in the denomination boxes 9-1, 9-2 and 9-3 through the transport units 8 and 3.

On the other hand, when the money receiving transaction is larger that the money paying transaction and one of the denomination boxes 9-1, 9-2 and 9-3 becomes full; the bills are taken out of the full denomination box, discriminated by the discrimination unit 4 for denomination and the number of sheets, and stored into the cassette 11. All bills may be collected to check the balance of the bills in the machine. The balance of the bills in the machine may also be checked while they are sequentially transported into the denomination boxes 9-1, 9-2 and 9-3 and the bill cassette 11 through the discrimination unit 4.

In FIG. 1, a disinfection unit 10 is provided on the path of the transport unit 3. The disinfection unit 10 disinfects (including sterilization and pasteurization) the bills transported by the transport unit 3. FIGS. 2 to 10 show specific embodiments of the disinfection unit 10.

In FIG. 2, an electromagnetic wave is irradiates the bills to disinfecting them. In the present embodiment, the disinfection unit (disinfection device) comprises a pair of ultraviolet ray lamps 21 and 21' arranged vertically relative to the transport unit in the path of the transport unit 20 which includes a belt 24 and a roller 25, reflection mirrors 22 and 22' arranged to cover the lamps 21 and 21', and guides 23 and 23' for holding the bills.

The disinfection (including sterilization and pasturization) means described above may be provided at any one of the positions 10, 10-1 and 10-2 in FIG. 1, or at any two positions or at three positions. The object of the present invention can also be achieved when they are provided at other position. The timing of the disinfection of the moneys may be in one of the transactions (1) to (7) or in a plurality of transactions. The moneys may also be disinfected during the checking of the moneys.

FIG. 15 shows a block diagram for explaining the control in the embodiment of the present invention. The bill handling unit 151 shown in FIG. 1 is controlled by a control unit 152, as it is in the exiting machine. The money disinfection means 153 is connected to the control unit 152 through a drive unit 154. The control unit 152 determines the start and stop timings of the disinfection means 153 in accordance with the transaction done by the money handling unit 151, the amount of bills stored, elapsed time and environmental conditions, and drives the disinfection means through the drive unit 154 in a manner to maximize the effect.

In order to attain full effect of the disinfection means which uses the ultraviolet ray lamp or the heated roller shown in FIGS. 2, 3 and 6 to 10, preheating may be required. The control unit 152 may always drive the heat supply source or drive it in response to the start of transaction caused by the user's manipulation.

In the embodiments of FIGS. 4 and 5 in which the ozone or drugs are applied, the disinfection unit is driven in timed relation with the transport of moneys. For example, as shown in FIG. 4, the money sensor 43 is arranged in front of the nozzle 41, the money detection signal from the money sensor 43 is sent to the control unit 152, which drives in response thereto.

FIG. 16 shows a diagram for explaining another embodiment of the control. In the present embodiment, a money sensor 173 for detecting the passage of the money and an encoder 166 for encoding a displacement along the transport path are provided in the discrimination unit 4. When the money passes through the discrimination unit 4, the time of passage of the money is informed to the control unit 162 by the money sensor 173. The encoder 166 sends the encode signal so that the control unit determines the position of the transport path along which the money is transported and drives the disinfection unit 163 through the drive unit 164 in the timed relation with the passage of the money through the disinfection unit.

In the embodiments of FIGS. 11 and 12 in which the disinfection is effected in the denomination box, the disinfection unit may be always driven or driven periodically by a timer of the control unit.

The disinfection of the bills have been explained in the above embodiments, although the unit of the present invention is also applicable to coins. It may also be widely applicable to other than automatic teller machines such as automatic vending machine and automatic ticketing machine. The present invention is also applicable to the disinfection sterilization and pasteurization of other than bills, such as sheets.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the present invention in its broader aspects.
