Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for withdrawing banknotes using a credit card. The bill withdrawal means is responsively controlled.

In known controls of this type, the withdrawal means are only capable of withdrawing banknotes by means of a control unit, which control unit is easily accessible from the outside, especially if the control signals arrive from a remote central unit. It is connected to the drawer means by a connecting means that can be connected to the drawer means. Such connection means are therefore susceptible to tampering, thus giving rise to incorrect activation signals or erroneous translations of control signals. Such inconveniences tend to occur more frequently when the withdrawal device is installed in a public place. Generally, this type of banknote withdrawal device is equipped with a strong box housing the withdrawal means and a unit for verifying the user's PIN number, but the control unit is usually located outside this box and therefore cannot be verified against the control unit. The unit and the connection means with the extraction means are easily accessible.

The aim of the invention is to eliminate the risk of malfunctions caused by the accessibility of the connection means between the withdrawal means and the control unit, and this aim is achieved by the banknote withdrawal device of the invention. The present invention
comprising a control unit that controls the banknote withdrawal means in response to a verification means that compares a personal identification number input by the user with a number stored on the credit card;
The verification means and the banknote withdrawal means are housed in a strong box, the control unit being located outside the box and also comprising a deterrent means for disabling the banknote withdrawal means. In a banknote withdrawal device utilizing a card, said restraining means is also located within said rigid box, said restraining means being adapted to directly disable said banknote withdrawal means independently of control by said control unit. connected to verification means, said inhibiting means being activated to disable said banknote withdrawal means by a signal indicating a mismatch between said two numbers in the result of said comparison and indicating a match in the result of said comparison; There is provided a banknote withdrawal device characterized by comprising a circuit that is inactivated by a signal and further activated by a signal indicating completion of the banknote withdrawal operation of the banknote withdrawal means.

Embodiments of the present invention will be described below with reference to the drawings.

The apparatus of the invention has a control unit 10, for example a microprocessor, arranged to control a series of peripheral units. Included among these peripheral units is a credit card reading and recording device 11 adapted to accept a credit card into a slot 12 and route this card to a reading and recording area. The credit card has a read-only track that holds a set of PIN data and a read and write track that holds accounting data that permits and records the withdrawal of a determined amount of banknotes within a predetermined cycle.
The device 11 allows the unit 10, under the control of the control unit, to display data read from the read-only track of the credit card on a display screen 14.
Based on the guidance information displayed above, the user is verified by comparing it with the secret password entered by the user on the keyboard 13.

The device also includes a banknote drawer unit 17 having one or more drawers each containing a corresponding type of banknote. After unit 11 checks the credit card, unit 1
7 is controlled by a central unit 10 based on the amount entered on the keyboard to withdraw a predetermined amount of various banknotes, stack them into bundles and present them to the user through a slot 18 in the front panel of the device.

When the unit 17 withdraws a predetermined amount of banknotes, the unit 10 controls the unit 11 to correct the amount of money that can be further withdrawn within a predetermined period on the reading and recording track of the credit card, after which the unit 11 withdraws the banknote from the slot 12. The credit card is returned to the user through The apparatus further comprises an envelope supply unit 22, which supplies a credit card based unit 1 as described above.
1 operates under the control of the central unit 10 following confirmation of the user by the user and execution of the requested operation at the keyboard. The user can place banknotes to be deposited into the envelope thus provided. The user then inserts the envelope containing the banknotes into the envelope collection unit 23, which stamps the envelope and sends it to the deposit drawer 24 under the control of the central unit 10.

The keyboard 13, the screen 14 and the slots for access to the units 17, 22, 23 are protected by a protective sliding plate 24' driven by a servo motor controlled by the central unit 10. The slide plate 24' is normally closed and opens only when the unit 11 confirms that the credit card inserted into the slot 12 of the unit 11 is valid.

The device is placed in a groove in the wall 26 of the bank so that users can directly access it from the outside. For this purpose, the device is housed in a metal cabinet 27 and consists of an armored container in the form of a strong box 28, the interior of which is accessible to bank employees through shutters 29 (FIG. 4). The strong box 28 houses the banknote drawer unit 17, the slot 18 (FIG. 3) of this unit being inserted into the strong box 28.
It is located at a position corresponding to the opening 31 at the top of. The sturdy box 28 also houses a deposit drawer 24 which is connected to the unit 23 via a slot 32 and a duct 33 in this box. The robust box 28 also houses a user identification unit 9 which is electrically connected directly to the unit 17. The power supply cables for units 9, 17 and the control cables between these units and central unit 10 extend through holes 34 (FIG. 3) in rigid box 28. In order to minimize the weight and cost of the device, the central unit 10, power supply unit 35,
Unit 11, keyboard 13, screen 1
4. Units 22, 23 and other necessary equipment (not shown) are located outside the rigid box.

The user identification unit 9 has a digitization circuit 36 connected to the central unit 10 by a serial interface 37 for receiving the amount digits read by the unit 11 from the read-only track of the credit card. This digitization is typically performed under the control of one or more algorithms stored in memory 38 and selectively retrieved by central control unit 10.

The verification unit 9 also has a comparison circuit 39 for comparing the number digitized by the circuit 36 with the user's secret PIN number. When this number is entered on the keyboard 13, it is
is sent to circuit 39 by control unit 10 via.

The circuit 39 issues an OK signal if both numbers match as a result of the comparison, and otherwise issues a signal N. These two types of signals are transmitted to the control unit 1 via two corresponding conductors 40, 48.
Sent to 0. When receiving the OK signal, the unit 10 allows the user to set the withdrawal amount. Here, the control unit 10 compares this set amount value with the value read by the unit 11 from the credit card and from the recording track. If the result of this comparison is positive, the control unit 10 issues a command to withdraw the corresponding amount of banknotes via the conductor 42. Conductor 42 is connected to a logic circuit 43 which controls a drive motor 44 for banknote withdrawal unit 17.

Logic circuit 43 is adapted to be inhibited by inhibit means constituted by a flip-flop 46 and located within rigid box 28. This flip-flop is set by a signal N from circuit 39 via conductor 41' in box 28 and by a signal N from circuit 39 via conductor 40' in box 28.
It is reset by OK. flipflop 4
6 can also be set by a signal D generated by a sensor sensing a stack of banknotes, thus indicating the end of the banknote withdrawal operation. Finally, flip-flop 46 is also set by a signal generated when the device is connected to the mains after it has been stopped for some reason. When set, flip-flop 46 inhibits logic circuit 43 via conductor 47, whereby bill withdrawal unit 17 is directly blocked. Flip-flop 46 is normally set, so logic circuit 43 is inhibited. The flip-flop is reset to activate circuit 43 only by the signal OK, which occurs when the comparison by circuit 39 matches. The OK signal causes control unit 10 to continue the transaction and send a withdrawal command to circuit 43 via conductor 42. When the bill withdrawal unit 17 signals the end of the withdrawal operation, the signal re-sets the flip-flop 46 and inhibits the circuit 43 again.

If any reason occurs, for example an accidental or erroneous activation of a junction on conductor 40 or conductor 42 of control unit 10, a signal is sent to circuit 43, but the signal OK
Since flip-flop 46 has not been reset by
It remains blocked regardless of control by
