Description

Apparatus and method for detecting banknote remaining amount in cash dispenser {APPARATUS AND METHOD FOR DETECTING THE REMAINDER NUMBER OF PAPER MONEY IN AUTOMATIC TELLER MACHINE}

The present invention relates to an automatic teller machine, and more particularly, to an apparatus and method for detecting banknote remaining amount.

In general, the ATM is configured such that the near end sensor 110 is mounted to a frame 140 into which the cash box 150 is inserted.

The near-end sensor 110 includes a light emitting sensor 111 and a light receiving sensor 112 that are fixed to a sensor bracket and are mounted to the frame 140 at both sides.

In FIG. 1, '130' is installed in the cash box 150 as a wheat plate and serves to push banknotes.

When the close plate 130 is transferred by a predetermined period by the payment of bills, the near-end sensor 110 is configured to open the through-hole 120 so that the light of the light emitting sensor 111 reaches the light receiving sensor 112.

The operation of detecting the remaining amount of bills in a general ATM will be described below.

As the banknote is paid in the cash box 150, the wheat plate 130 pushes the banknote toward the discharge port side.

At this time, when there are enough bills in the cash box 150, the through-hole 120 is blocked by the bills as shown in FIG. 2 (a). It does not reach the light receiving sensor 112.

Subsequently, as the bill is discharged, the amount of the bill decreases, and when the plate 130 is moved from the position of the through hole 120 to the discharge port side, the through hole 120 is opened and the near-end sensor 110 is shown in FIG. As described above, the light of the light emitting sensor 111 reaches the light receiving sensor 112.

At this time, the automatic teller machine recognizes the end (Near End) state in which there are few bills remaining in the cash box 150 and informs the manager of this.

That is, the light emitting sensor 111 and the light receiving sensor 112 of the near-end sensor 110 is fixedly mounted at a proper position of the frame 140 into which the cash box 150 is inserted, so that the bill is notified if only a predetermined amount remains. will be.

However, conventionally, the following disadvantages exist.

1. The sensitivity decreases depending on the relative distance, so it only detects the approximate amount of bills, but not the correct amount of bills.

2. If it is about 5mm apart, the bill is thin enough to hold 50 bills, so the last sheet cannot be detected even if the sensor is moved to the exit.

3. The amount of paper money can be detected only after the plate is in close contact with the paper plate so that the remaining amount of paper money changes according to the flow and shape of the paper plate, thus reducing the accuracy.

4. Each banknote is different in thickness, so the position of the sensor must be changed to detect that a certain number of banknotes remain.

Therefore, in order to solve the conventional problem, the present invention inserts a special bill with a specific recognition pattern between the bills in the cash box, and detects a specific recognition pattern of the special bill as the bills are issued. An object of the present invention is to provide an apparatus and method for detecting banknote remaining amount of a financial automatic device.

The present invention is a bill detection sensor for detecting the pattern of bills emitted from the cash box to achieve the above object, a branch for transferring a special bill or damaged bills and general bills in different transport paths, the bill detection sensor Analyzes the detected pattern to determine the banknote type and controls the operation of the branch according to the determination result, and if the discrimination result is a special banknote, a banknote type determination unit for calculating the remaining amount of the banknote in the current cash box is configured. It features.

The bill detection sensor is characterized in that the bill feed detection sensor (Feed Sensor) mounted on the bill outlet of the cash box.

The bill type determining unit is configured to determine the bill type mounted in each cash box according to a specific pattern of the special bill detected by the bill detection sensor during the initial startup of the automatic teller machine.

In addition, the present invention is to insert a special banknote formed with a specific pattern at any position of the banknotes mounted on the cash box in order to achieve the above object and to record the insertion position, and to determine whether a specific pattern is detected during bill transfer And determining the remaining amount of the bill by comparing the insertion position information of the special bill inputted above when the specific pattern is detected.

The process is characterized in that it comprises the step of determining the type of bills mounted in each cash box during the initial bill transfer when the insertion position of the special bill is the first sheet.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the embodiments of the present invention, a detailed description of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Figure 4 is a block diagram of a bill remaining amount detection device for an embodiment of the present invention, as shown in this, a special bill or damaged bills to be transported to the collection box 440 and the general bills to the discharge box 450 By analyzing the base 430, the bill detection sensor 410 for detecting the pattern of the bill, and the pattern detected by the bill detection sensor 410, it is determined whether it is a special bill, a damaged bill or a general bill, and the decision is made. According to the result, it comprises a bill type determination unit 420 for controlling the operation of the branch unit 430.

The bill detection sensor 410 is a bill supply detection sensor installed in front of the discharge port of the cash box.

The bill type determination unit 420 is configured to include a firmware for reading the remaining amount of the bill in the cash box when the discharge bank is determined to be a special bill.

Unexplained reference numeral '460' in the drawing is an upper system for the bill type determining unit 460 to inform the manager that there are almost no remaining bills by reading the special bill.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

The special banknote of this invention is produced as shown to the illustration of FIG. 3 (a) (b).

The special banknote of Fig. 3 (a) has a permeable material such as cellophane paper and an OHP film, and is configured to give a specific function by adjusting the intervals and widths of the black bands so as not to transmit light.

The special banknote in Fig. 3 (b) is a semi-permeable material such as plain paper, and is configured to give a specific function by drilling holes of a predetermined type.

And the recognition pattern formed in the special banknote can be variously formed as needed.

In the embodiment of the present invention will be described the process of detecting the remaining amount of bills.

When the bill is released from the cash box, the bill detection sensor 410 reads the pattern formed on each bill.

That is, the banknote detecting sensor 410 includes a light emitting sensor and a light receiving sensor, and when the banknote is supplied from the cash box to the conveying belt, the light of the light emitting sensor is blocked or passed by the recognition pattern formed on the banknote and the light passed therethrough is As the incident light enters the light receiving sensor, a signal corresponding to the recognition pattern is transmitted to the bill type determining unit 420.

The banknote type determination unit 420 has a firmware for reading damaged banknotes, banknotes supplied with two sheets or banknotes normally supplied, and special banknotes, and analyzes the value read by the banknote sensor 410. Determine whether it is a special bill or a general bill.

For example, when a general banknote is transferred, as shown in FIG. 5 (a), the light of the light emitting sensor is blocked by the width of the banknote and transmitted to the banknote type determination unit 420 from the banknote detecting sensor 410. The waveform of is obtained as shown in Fig. 5B. Here, 'T' is the time when the bill passes by one sheet width.

And, when a special bill is transferred, as shown in Figure 6 (a), because there is a part through which light is transmitted at a specific position of the bill, the bill detection sensor as shown in Figure 6 (b) by the transmission and blocking of light A particular type of signal waveform is obtained with the periodic on / off time of 410.

That is, in the case of a special bill, it is turned off at the portions of 'T1', 'T3', and 'T5' within the detection time T to obtain a waveform of a specific shape.

Accordingly, the banknote type determination unit 420 controls the branching unit 430 by determining whether to transfer the banknote to the discharge box 450 or the recovery box 440.

In addition, the banknote type determination unit 420 recognizes how much of the bill remaining in the current cash box when a specific waveform is obtained by the transfer of the special banknote.

For example, if the special bills are placed one by one at the end, near end, or in units of 100 sheets, it is possible to accurately determine the remaining amount of bills in the current cash box by determining when the special bills are discharged.

7 is an exemplary view showing a position of inserting a special bill between bills in the cash box to determine the time point at which the inserted special bill is discharged to recognize the remaining amount of bills.

That is, in Figure 7, banknote 1 can know the position of the end (Near End) banknote and banknote 2 can tell that the last banknote discharged.

Therefore, when the transfer of the special bill is detected, the banknote type determination unit 420 controls to release the special banknote from the branch 430 to the collection box 440, and the current banknote is almost discharged to the upper system 460. It tells you that there are not enough extra bills in the cash box.

On the other hand, the types of banknotes currently handled by ATM machines are not limited to one book type, but use multiple books (eg 1,000 won, 5000 monthly, 10,000 won).

Therefore, in the embodiment of the present invention, since the special banknotes can be produced various recognition patterns according to the required function, it is easy to determine the use winding type of each cash box without adding a separate sensor using a special banknote corresponding to each winding type. To be able.

In other words, the current cash box is used to mix the different types according to the different types of paper, so that separate types of paper using separate sensors, but if you put a special bill for each kind of paper produced for the present invention at the very beginning of the bill release It is easy to determine which kind of banknote is loaded in which cash box.

In addition, the technology for detecting the remaining amount of bills has been described above, but it can be implemented to determine the remaining amount of the printing paper by applying it to the printing paper.

That is, the present invention includes inserting a special paper having a specific pattern formed at a specific position of the printing paper mounted on the ATM and recording the insertion position, determining whether a specific pattern is detected when printing the paper, and specifying the specific pattern. If this is detected, it is possible to implement the step of determining the remaining amount of the printing paper by comparing with the insertion position information of the special paper inputted above.

As described in detail above, the present invention can improve the disadvantage that the position of the end sensor (Near End Sensor) in the prior art is not fixed to meet the needs of customers according to the number of charges. There is.

That is, the present invention can be used to change the end (Near End) position according to the customer's request by using a special banknote formed with a recognition pattern, as well as the effect of accurately knowing the remaining amount of bills without adding a separate sensor have.

Therefore, the present invention can accurately know the timing of the installation of the bill, so that the manager can flexibly cope with the effect that can give confidence to the customer.

In addition, since the present invention can accurately know the remaining amount of bills without adding a separate sensor, there is an effect that can be applied to the existing automatic cash dispenser.
