Description

Paper Money Recognizing Apparatus {Paper money Recognizing Apparatus}

The present invention relates to a banknote identification device installed in a vending machine or a coin exchanger, and operated by recognizing the authenticity of banknotes such as banknotes or gift certificates input by a user. The present invention relates to a banknote identification device that can prevent theft acts to obtain the effect of the input of the pneumoconiosis by forcibly returning the introduced pneumoconiosis after withdrawing goods and the like.

In recent years, as sales of vending machines have increased, the spread of unmanned vending machines that can buy commodities using large bills, coin exchangers that can exchange bills for coins, and unmanned vending machines such as game machines and entertainment machines has been expanded. .

Usually, an unmanned vending machine is provided with a banknote identification device that can determine the authenticity and type (face value) of the banknotes put by the user. Such banknote identification device is to identify whether the banknotes put out or counterfeit by the banknote identification unit, in the case of counterfeit is to be returned to refuse. And, if the inserted banknote is a pulsation allowed by the device, and outputs a predetermined electrical signal according to the face value of the inserted banknotes to operate the normal operation to discharge the goods of the vending machine or exchange coins in the coin exchanger according to the user's selection, The inserted bill is operated to be stored in the bill storage.

On the other hand, coin exchangers and unmanned vending machines equipped with the above-mentioned banknote identification device have recently emerged as a target of theft by various methods such as the clever disturbing mechanisms. Has become. For example, when the pneumoconiosis, which is attached to a thread or tape in the form of a long tail, is introduced, the bill recognition device does not recognize the attachment state of the thread or the tape, and withdraws goods or coins through a normal operation process. Thereafter, by using the thread or tape attached in the form of the tail, forced repatriation and withdrawal of the introduced pneumoconiosis have the effect of introducing the pneumoconiosis, and the introduced pneumoconiosis has the problem that illegal theft can be withdrawn again.

An example of the tort described above will be described with reference to FIGS. 1A and 1B.

When a user inserts a bill into the bill input slot 3, the bill B passes through the lower roller 4 and the upper roller 5, and is provided with a bill detecting sensor installed in the upper guide part 6 and the lower guide part 7. The authenticity and face value of the banknote B put in (not shown) are judged. If the inserted bill (B) is pulverized, the bill identification device (1) continues to transfer the bill (B) to the lower roller 4 and the upper roller (5) and placed in the state shown in Figure 1, then the bill (B) After the electrical signal corresponding to the liquid level of the output to the main body (not shown) and waits. Thereafter, when a work completion signal such as product sales is input from the main body, the banknote identification device 1 transfers the banknote B to the banknote storage unit 10.

By the way, in the conventional banknote identification device, when the thread or the tape 20 is attached to the rear end of the inserted banknote B as shown, the bill completion device 1 outputs an electrical signal and then the work completion signal is output. While waiting for input, the user can pull the thread or tape 20 or the like to forcibly withdraw the bill B. FIG. In other words, while maintaining the effect of inputting the pneumoconiosis which can withdraw goods, etc. from the vending machine, etc., there was a problem that the input pneumoconiosis can be recovered.

In order to prevent the problem as described above, when the inserted banknotes are installed in the banknote identification device, the inserted banknotes are forcibly pulled out by outputting an electrical signal to the main body and simultaneously operating the blocking plate to block the bank entrance. A number of devices have been devised and used that cannot be used.

However, in the banknote identification device applying the method described above, when a user who puts an abnormal banknote with a thread or a tape pulls the thread or the tape to collect the banknote, the banknote is torn or jammed by the blocking plate. There is a problem that occurs if the bill identification device does not operate normally.

On the other hand, it is a method that emerged to perform illegal activities by avoiding the above problems, and primarily detects abnormal bills with a thread or tape attached so that the user cannot detect the bill sensor or the blocking plate of the bill identification unit. After normal operation, the device is operated normally, and then the counterfeit prepared separately is introduced into the lower part of the already inserted paper money to induce a reaction action such as a bill detection sensor and a blocking plate of the paper money identification part. The barrier plate is induced to be opened in the reverse discharge process, and there is a problem in that the banknote is pulled out by pulling the thread or tape to force the banknote back into the counterfeit.

The present invention was devised to solve the problem in view of the problems of the conventional bill vending machine as described above, the object of the present invention is to identify the vending machine without disturbing and disturbing even when the bill is input in an abnormal way It is controlled not to send electrical signals for selling goods to the main body equipment such as to prevent the sale of goods, or to block the withdrawal by artificial forced repatriation of abnormally inserted bank notes at the same time to obtain the effect of inserting banknotes. It is an object of the present invention to provide a banknote identification device capable of eradicating illegal theft of money redrawing.

It is preferable to provide two blocking sensors 144 as far as possible in the width direction of the blocking plate 140 so as to reliably detect the rise of the blocking plate 140. As the cutoff sensor 144, various types of sensors may be used, but it is preferable to use a photoelectric sensor.

In addition, the tension bar 150 is installed in parallel with the blocking plate 140 in front of the blocking plate 140, that is, spaced apart a predetermined distance toward the banknote opening 101. It is installed to more surely detect the abnormal bank by the blocking plate 140. The tension bar 150 has a rod-shaped shaft 151 at both ends having a rod shape, and has a length substantially the same as that of the blocking plate 140, and the weight thereof is applied to the thread or tape attached to the banknote to block the plate 140. ) Is set to such an extent that it is prevented from being raised. In addition, the diameter of the tension bar 150 should have a size that can be conveyed smoothly to the banknote is put. In addition, the upper surface of the lower guide portion 110 is formed with a mounting groove 155 on which the tension bar 150 can be mounted. This seating groove 155 is V-shaped, as shown in Figure 4, it is preferable that the outer peripheral surface of the tension bar 150 is formed in a size that can contact both sides of the seating groove 155. In addition, both side walls 112 of the lower guide portion 110 is formed with a shaft groove 117 for guiding the rotating shaft 151 so that the tension bar 150 can be elevated and rotated. The upper portion 117a of the shaft groove 117 is machined to the size to be fitted with the rotation shaft 151, the lower portion 117b is processed so that the rotation shaft 151 is loose fitting.

Accordingly, when the bill B is drawn in by the lower rollers 114a, 114b, 114c, 114d and the upper rollers 124a, 124b, 124c, 124d as shown in FIG. 5A, the tip of the bill B is inserted. Enter between the tension bar 150 and the seating groove 155 to lift the tension bar 150 and at the same time while continuing the transfer while rotating the tension bar 150, passing through the upper side of the blocking plate 140 banknote outlet ( 102).

Banknote detection sensor 160 is installed in a plurality of lower guide portion 110 and the upper guide portion 120 so as to check the authenticity of the bill (B) passing through the transfer path 103 and the type of the bill (B). In general, optical sensors and magnetic sensors are used. The banknote detection sensor 160 may be installed in various positions with a variety of sensors according to the type of banknotes (B) to be injected. In addition, it is preferable to install an input detecting sensor that can detect whether the banknote (B) is inserted in front of the banknote sensor 160.

The control unit 170 is installed under the lower guide unit 110, the control device of the main body (not shown) and the signal input from the input detection sensor or bill detection sensor 160 and the banknote identification device 100 is installed (not shown) By controlling the motor 130 by using the signal input from the (c) to discharge the bill (B) to the outside or to maintain the standby state or transfer to the bill storage unit (10 in FIG. 1). When a normal banknote is input, an appropriate signal is output to the control unit of the main unit so that the main unit can sell a product or perform a coin exchange.

2 and 3, reference numerals 131a and 131b are protruding ribs integrally formed at rear portions of the lower guide portion 110 and the upper guide portion 120, respectively, and the protruding ribs 131a and 131b. One end of each bank has a structure formed so as to protrude obliquely in a direction opposite to each other, when the bank end is forced to withdraw through the thread or tape 20 in the state in which the bill is normally fully inserted, the rear end of the bill The protrusion ribs 131a and 131b are prevented from being easily pulled out and serve to function.

Hereinafter, the operation of the banknote identification device according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

When the bill B is input, the input detection sensor detects the bill B and outputs a bill detection signal to the controller 170. Then, the control unit 170 receives the bill detection signal to drive the motor 130 so that the lower roller (114a, 114d) to convey the bill (B). The front end of the banknote (B) to be transferred enters between the tension bar 150 and the seating groove 155, as shown in Figure 5a is to move forward while raising and rotating the tension bar 150. At this time, the control unit 170 checks whether the inserted banknote B is a counterfeit or pneumococcus using the banknote detecting sensor 160. If the counterfeit, the motor 130 is rotated in reverse so that the bill B is carried out to the bill input hole 101 again. In the case where the inserted banknote B is pulsating, the face value of the banknote B is determined, and the motor 130 is continuously driven to move the banknote B to the banknote discharge port 102. When the rear end of the banknote B passes through the upper portion of the blocking plate 140 as shown in FIG. 5B, the controller 170 turns off the solenoid 145. Then, the blocking plate 140 is raised above a certain height by the elastic force of the spring 147. The rising height of the blocking plate 140 is limited by the stopper 141 formed at the lower end of the blocking plate 140.

If the inserted banknote B is puffed and at the same time a normal banknote (hereinafter referred to as 'normal banknote') with no thread or tape 180 attached to the rear end, the blocking plate 140 is raised to the maximum height. When the blocking plate 140 rises to the maximum height, the blocking sensor 144 installed in the upper guide part 120 detects an upper end of the blocking plate 140 and outputs a detection signal to the controller 170. Then, the control unit 170 outputs a signal indicating that the normal banknotes are put into the control device of the main body while the bill (B) is maintained to wait in the standby position. Then, the controller of the main body performs an operation of selling goods or exchanging coins according to the user's selection. The control device of the main body outputs a work completion signal to the control unit 170 of the banknote identification device 100 at the same time or after completing the specific operation. When the control unit 170 receives the work completion signal from the control device of the main body, by driving the motor 130 to rotate the lower rollers (114a, 114b, 114c, 114d) in the direction of the bill discharge port 102 bill (B) Drop to the bill storage portion (10).

If the inserted banknote B is puffed out but is an abnormal bill with a thread or tape 180 attached to the rear end, as shown in FIG. 5C, the rise of the blocking plate 140 is interrupted by the thread or tape 180 or the like. Will receive. At this time, since the thread 180 attached to the rear end of the banknote B is pressed by the tension bar 150, the thread 180 is tensioned by the rising blocking plate 140 and the tension bar 150. As a result, the rise of the blocking plate 140 is prevented. In particular, due to the installation of the tension bar 150 and the mounting groove 155, the thread 180 is thin enough to be inserted into the gap between the groove 121 formed in the blocking plate 140 and the upper guide plate 120 Even in this case, it is possible to prevent the blocking plate 140 from rising to the maximum height. As such, when the rising of the blocking plate 140 is disturbed by the seal 180, the blocking plate 140 may not rise to the detection position of the blocking sensor 144. Then, since the blocking sensor 144 does not output the blocking plate 140 detection signal, the control unit 170 automatically returns the normal bank input signal without outputting it to the control device of the main body. Therefore, the user who put the abnormal banknote can not withdraw the goods loaded on the vending machine or exchange coins. Therefore, according to the banknote identification device 100 according to the present invention, since the vending machine or the coin exchanger does not operate when the user inputs the abnormal banknotes, it is possible to prevent illegal acts by inserting the abnormal banknotes to obtain a puffing effect. Can be.

Hereinafter, the operation state of the banknote identification device according to the present invention will be described with reference to the accompanying drawings through the description of the control process so that the main body does not operate normally when abnormal banknotes are put into the banknote identification device according to the present invention.

The input detection sensor checks whether the bill B is inserted into the bill input hole 101, and outputs an input signal to the controller 170 when the bill B is input (S100).

Then, the controller 170 drives the motor 130 to allow the lower rollers 114a, 114b, 114c, 114d to move the banknote B toward the banknote outlet 102. At the same time, the controller 170 checks whether the inserted bill B is a counterfeit bill using the bill detection sensor 160 (S200). In the case of a counterfeit bill, the motor 130 is rotated in the reverse direction, and then the inserted bill B is carried out to the bill input hole 101 again (S210). In the case of pneumoconiosis, the type of the bill (B), that is, the face value, is checked and the motor 130 is driven to move the bill (B) to the bill discharge port 102. When the rear end of the banknote B passes through the upper portion of the blocking plate 140, the control unit 170 turns off the solenoid 145 to raise the blocking plate 140 (S300).

Subsequently, the controller 170 checks whether the blocking plate detection signal is input from the blocking sensor 144 (S400). When the detection signal is input from the blocking sensor 144, since the normal money is input, the control unit 170 outputs the normal money input signal indicating that the normal money is put together with the face value of the inserted money (S500).

When the control device of the main body receives the normal bank input signal from the control unit 170 of the banknote identification device, it performs a certain operation in a predetermined order.

If the detection signal is not received from the blocking sensor 144 even after the control unit 170 raises the blocking plate 140, the control unit 170 does not output the normal bank input signal to the main body (S600). At this time, if a detection signal is not received from the cutoff sensor 144 even after a predetermined time elapses, the controller 170 may determine that an abnormal banknote is input and designate an operation according to a predetermined processing method. In this case, various methods such as waiting for a bill without performing any subsequent operation in the state of maintaining the bill in the standby state or discharging the abnormal bill to the bill insertion slot by rotating the motor may be considered.

As described above, according to the banknote identification device and its control method according to the present invention, since abnormal money with a thread or a tape attached to the rear end of the pneumoconiosis can be detected, the abnormal money is inputted from the vending machine. Illegal acts, such as withdrawing goods and exchanging coins, can be prevented.
