DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a media pressure control method and apparatus according to a preferred embodiment of the present invention and a media checkout apparatus using the same will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing the configuration of a bill receiving and dispensing apparatus including a stacking cassette for detecting a position of a stacking plate according to a preferred embodiment of the present invention. FIGS. 3A and 3B show a detailed configuration of the stacking cassette shown in FIG. Are shown in plan and side sectional views.

As shown in these figures, the bill depositing and dispensing machine of the present invention is provided with a stacking cassette 10 for stacking banknotes to be discharged at the time of withdrawal transaction. The loading cassette 10 is detachably attached to the bank note depositing and dispensing machine.

The stacking cassette 10 is provided with a discharge module 17 for discharging the stacked banknotes to the outside. First and second pick-up rollers 17a and 17b for picking up the stacked bills are provided in the discharge module 17 so as to be spaced apart from each other by a predetermined distance so as to pick up both sides of the bills. The emission module 17 is provided with a pickup motor 17c for driving the first and second pickup rollers 17a and 17b.

A position sensor (hereinafter abbreviated as "sensor") 18 for sensing that the release module 17 is moved to a preset release position due to a pressing force applied by the plate 11, . The discharge position is a preset position by an experiment so that the discharge module 17 can separate and discharge the stacked bills one by one. When the sensor 18 senses the emission module 17 and outputs an ON signal, the control unit 20, which will be described below, stops driving the motor 12.

The discharge module 17 is provided with a plate 11 for applying a pressing force to the bill in the discharge direction, that is, in the direction of the arrow A, so as to discharge the bill one by one. The plate 11 may be formed of a conductor to form an electric current path. This is for solving the static electricity problem of the banknote loaded on the stacking cassette 10. However, when the whole of the plate 11 is formed of a conductor, manufacturing cost is increased. Therefore, in the present embodiment, the plate 11 is formed of a non-conductive material such as synthetic resin. In this case, in order to form a current path between the first and second guides 13a and 13b, which will be described below, the first and second guides 13a and 13b are formed at both sides of the plate 11 at intervals corresponding to the length of the banknote. A pair of connecting portions 11a and 11b are formed in a cylindrical shape having a through hole 11 'to which the connecting portions 13a and 13b are connected. The connection portions 11a and 11b are formed of a conductive material electrically connected to the plate guide 11. [ A connection line 11c for electrically connecting the pair of connection portions 11a and 11b is provided in the inside of the plate 11. In the present embodiment, the resistance of the connection portions 11a and 11b and the connection line 11c of the plate 11 is 0 ?.

A transfer member for moving the plate 11 is installed closer to the left and right sides of the stack cassette 10 than the first and second guides 13a and 13b. The conveying member is provided with a motor (12) for generating rotational power for moving the plate (11). The driving ratio of the motor 12 is adjusted according to the amount of the stacked bills. The motor 12 may be a direct current motor or a step motor. The conveying member is provided with a first pulley 12a connected to the rotating shaft of the motor 12 and a belt 12c for transmitting the driving force of the first pulley 12a and a driving force of the belt 12c A second pulley 12b rotating in the same direction as the first pulley 12a is provided.

In the loading cassette 10, a plate guide 13 is provided so that the plate 11 is moved horizontally for the purpose of releasing and storing banknotes. In the present embodiment, the plate guide 13 is installed in the longitudinal direction of the loading cassette 10, and first and second guides 13a and 13b are installed on the right and left sides. A power supply terminal for supplying a direct current driving voltage VCC is connected to the first guide 13a of the plate guides 13 and a reference resistor 14 having a preset resistance value is connected to the second guide 13b And grounded. The plate guide 13 functions as a resistor. For this purpose, the plate guide 13 is formed of a resistive material having a predetermined resistance value such as tungsten, or a non-conductive material such as synthetic resin, so as to have a predetermined resistance value by being coated with a nickel coating or a cadmium coating. In the present embodiment, it is assumed that the plate guide 13 has a resistance value between 0? And 10? K depending on the position at which the plate 11 is moved. One guide for performing the function of the resistor among the above-described plate guides 13 is sufficient. However, since the position of the plate 11 can be accurately detected as the change in the resistance value increases, the first and second guides 13a and 13b are all formed of a resistor material. The output terminal Vout between the second guide 13b and the reference resistor is connected to an output terminal OUT for outputting a plate position detection signal (hereinafter referred to as a detection signal) PS capable of detecting the position of the plate 11 . The output section is provided with a low-pass filter (15) for filtering the detection signal (PS) output from the second guide (13). The low-pass filter 15 removes a noise component having a frequency higher than a preset reference frequency. An analog-to-digital converter (hereinafter abbreviated as "converter") 16 for converting the filtered detection signal PS from an analog signal to a digital signal is provided. A current path is formed through the first guide 13a and the connecting portions 11a and 11b of the plate 11 and the connecting line 11c and the second guide 13b. When the plate 11 is moved in the discharge direction A according to the guidance of the plate guide 13, the detection signal PS is output through the output unit according to the current position of the plate 11. [ Specifically, the detection signal PS is summarized by the following equation (1).

At this time, PS: the voltage level of the detection signal

Rp: Composite resistance value of the first and second guides per plate position

Rs: resistance value of reference resistance

VCC: DC drive voltage

The combined resistance value of the first guide 13a and the second guide 13b with respect to the DC driving voltage VCC supplied to the first guide 13a and the resistance of the reference resistor 14 And outputs the detection signal PS by multiplying the result by the DC driving voltage VCC. That is, the detection signal PS is output differently depending on the position of the plate 11.

And a detector 19 for detecting the current position of the plate from the voltage level of the detection signal PS output from the converter 16. [ The detection unit 19 detects the amount of the detection signal PS as the composite resistance value of the first and second guides 13a and 13b increases when the plate 11 is moved from the initial position to the full discharge position. The current position of the plate 11 is detected by using the gradually decreasing voltage level.

A control unit for controlling the driving of the motor 12 so as to move the plate 11 to an appropriate position predetermined for each transaction to be performed based on the current position of the plate 11 detected by the detecting unit 19 20 are provided. The control unit 20 controls the plate 11 to move to a proper position corresponding to a transaction to be performed at each transaction. That is, the control unit 20 drives the motor 12 in the direction of the arrow B so that the loading cassette 10 can be mounted on the bank note depositing / dispensing machine or can discharge the stacked bank notes during the withdrawal transaction, 11) to the stacked bill. The control unit 20 drives the motor 12 in the direction opposite to the arrow B to form a space in which the banknote to be loaded is stacked, In the direction opposite to the direction of the arrow A. In addition, the control unit 20 controls the driving of the motor 12 to stop when the stacked bill is pushed in the discharging direction and the discharging module 17 is moved to the discharging position.

The bank note depositing and dispensing machine is provided with a display and input unit 21 for displaying various operation menus and operation states and receiving a transaction selection and operation command from a customer.

Next, a method of controlling the paper currency pressing force of the bank note depositing and dispensing machine according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 4, 5A and 5B.

In the present embodiment, it is assumed that the current position of the plate is detected in accordance with the banknote withdrawal transaction command, and the driving of the motor is controlled so as to press the banknote with the plate mounted thereon in the discharge direction based on the detected position.

In this embodiment, the first and second guides each have a resistance value of about 10 k ?, and the resistance value of the connecting portion and the connecting line of the plate is assumed to be 0 k ?, and the reference resistance has a resistance value of 1 k? Explain.

FIG. 4 is a flowchart illustrating steps of a bank note withdrawal transaction method using the method of detecting a position of a banknote depositing and dispensing machine according to a preferred embodiment of the present invention. FIGS. 5A and 5B are diagrams Is a table and a graph illustrating the composite resistance value by the plate position and the voltage level of the plate position detection signal according to the position.

4, the control unit 20 controls the motor 12 so that the stacked banknotes can be discharged through the discharge module 17, and then the banknote dispenser 10 To press the plate 11, and then waits until a withdrawal transaction command is input. For convenience of explanation, it is assumed that the stacked cassettes 10 are loaded with banknotes in a full state. At this time, a current path is formed through the connecting portions 11a and 11b of the first guide 13a and the plate 11, the connecting line 11c, and the second guide 13b.

In step S12, the display and input unit 21 selects a withdrawal transaction from the customer and receives a banknote withdrawal transaction command.

In step S14, the first guide 13a is continuously supplied with the DC driving voltage VCC under the control of the controller 20. [ The combined resistance value Rp of the first and second guides 13a and 13b and the reference resistor 14 divide the direct current driving voltage VCC by the equation 1 and form the second guide 13b The output terminal Vout between the reference resistors 14 outputs the detection signal PS of the divided voltage level. Then, in step S16, the low-pass filter 15 filters out the noise component from the detection signal PS using only a signal less than a predetermined reference frequency. Subsequently, in step S18, the converter 16 converts the filtered detection signal PS from an analog signal to a digital signal.

In step 20, when the plate 11 is moved from the initial position to the full discharge position, the detection unit 19 detects a detection signal (a) as the combined resistance value of the first and second guides 13a and 13b increases, PS is gradually decreased to detect the current position of the plate 11. In step S22, the control unit 20 drives the motor 12 in the direction of arrow B so as to execute the withdrawal transaction command based on the detected current position, That is, in the direction of arrow A.

In step 24, the control unit 20 controls the discharge module 17 to discharge the stacked banknotes, because the plate 11 is pressed to the position where the discharge module 14 can discharge the banknote. . At this time, the pickup motor 17c of the emission module 17 is driven and the pickup rollers 17a and 17b rotate in the direction of arrow D. As a result, the stacked banknotes are separated one by one and discharged to the outside of the stack cassette 10.

In step 26, the controller 20 uses the sensor 18 to check whether the release module 17 pressed by the plate 11 is moved to a preset release position. The discharge position is a position set by an empirical value so that the discharge module 17 can separate and discharge the banknotes one by one. When the emission module 17 is moved to the release position and the sensor 18 outputs an ON signal, the control unit 20 stops driving the motor 12 in step 28 (S28).

In step S30, the control unit 20 checks whether the banknote to be discharged is left in the loading cassette 10, and repeats the 24th step (S24) to the 30th step (S30) until all the banknotes are discharged .

As the withdrawal transaction is repeatedly performed, the amount of the banknotes stacked on the stacking cassette 10 is reduced. As a result, as shown in FIGS. 5A and 5B, the combined resistance value Rp of the first and second guides 13a and 13b is increased to And the voltage level of the detection signal PS is reduced to be close to 0V. Since the detection signal PS is continuously output by the combined resistance value Rp that changes according to the moved current position of the plate 11, the present invention is to continuously detect the position of the plate 11 It is possible. In the present invention, since the position of the plate 11 can be detected by using the detection signal PS while the DC driving voltage VCC is supplied, the information obtained by counting the number of banknotes in the power- There is no need for a separate memory provided for storing the positional information of the plate 11.

In step S32, the controller 20 checks whether a new transaction command is input through the display and input unit 21. If a new transaction command is input, the controller 20 proceeds from step S14 to step S32. Repeat this process.

If the new transaction command is a deposit transaction command, the control unit 20 controls the motor 12 to drive the motor 12 in the direction opposite to the arrow B so as to form a loading space for the bill to be charged in step 22, (11) is moved by a predetermined distance in the direction opposite to the discharge direction (A). It should be noted that, in step S24, the discharging module 11 is driven in the direction opposite to the arrow D so as to control the bill to be loaded into the loading cassette 10.

Through the above-described process, the present invention accurately detects the current position of the plate using a detection signal whose voltage level is variable according to the position of the plate, and moves the plate to a proper position for each transaction.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent that various modifications, alterations, and other equivalent embodiments are possible. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

Although the above embodiment has been described using a banknote depositing and dispensing machine, the present invention can be applied not only to banknotes but also to a financial issuing machine for issuing and receiving check, a vending machine, a currency exchange, and a medium issuing machine for issuing various certificates and tickets.

In the above embodiment, the first and second guides have a predetermined resistance value in order to accurately detect the position of the plate. However, only one plate guide can be changed to have a predetermined resistance value. 1 and the second guide may be changed to resistors having predetermined resistance values. At this time, the connection portion and the connection line of the plate are removed. In addition, the resistor may be changed into various shapes such as a band guide and a wire formed on the moving path of the plate, as well as the guide of the plate.

In the above embodiment, the current position of the plate is detected by using the voltage level of the detection signal. However, the present invention stores the voltage level table for each plate position in the main memory of the medium handling apparatus according to the experiment, It may be changed to detect the current position.
