Usually, the unmanned vending machine is provided with a bill identification device that can determine the authenticity, type and face value of the bill put by the user. Such a banknote identification device identifies whether a banknote is put out or counterfeit by the banknote identification unit, and operates in a case where counterfeit is rejected and returned to the banknote.

By the way, in recent years, theft using a structure such as an unmanned vending machine or a coin exchanger equipped with a banknote identification device has frequently occurred. Such stealing is mainly used to insert a bill attached to the rear end of the pneumoconiosis in the form of a long tail with a thread or tape.

That is, since the banknote itself does not have any problem, since the banknote itself has no problem, when the illegal user inputs the banknote with the thread or tape, the inserted banknote is a dustbin, and thus it is recognized and stored along the banknote transfer path. Is moved. The fraudster can then secure goods and change money equal to the face value of the inserted banknote. The fraudster who secures the goods and the change money, while still holding the thread or tape exposed outside the bank, inserts a fraudulent bill like a paper or a card, and the bill recognizer detects the fraudulent bill. Perform a reject return action. When such a rejection return operation is performed, at the same time, the illegal user pulls out the thread exposed to the outside, and then, together with the discharged negative bill, it is possible to recover the first put-in pneumatic connected to the thread. Accordingly, there is a problem that the vending machine operator loses as much as the face value of the banknote to which the thread is connected, so that security measures are urgently required.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a banknote identification device having an improved structure so as to prevent an illegal method of recovering the injected dust.

Banknote identification device according to the present invention for achieving the above object is the upper and lower cases coupled to the upper and lower plates to form a bill transfer path; A shutter unit having a first position at which the banknote opens the channel and a second position at which the banknote is closed; A drive unit which rotationally drives the shutter unit to the first and second positions; And a banknote detecting sensor installed inside the lower plate to sense whether a banknote is inserted or not, wherein the shutter unit has a plurality of rows of blocking members formed of a plurality of protrusions intersected with each other.

According to a preferred embodiment of the present invention, the shutter unit is installed in the space portion between the upper case and the upper plate, it is preferable that the first and second blocking members arranged cross each other is composed of two rows.

Banknote identification device according to the present invention may further include a detection unit for detecting the position of the shutter unit.

In this case, the driving unit, when the bill detection sensor detects that the inserted bill passes through the bill transfer path, it is preferable to rotate the shutter unit to the second position.

As shown, the banknote identification device 100 according to the present invention includes an upper and lower case 110, 120, a shutter unit 200 and a drive unit (M, see Fig. 5a) capable of opening and closing up and down, The banknote guide 130 which can guide banknote insertion in front is provided.

An upper plate 110a is coupled to the upper case 110, and a shutter unit 200 is installed in the inner space between the upper case 110 and the upper plate 110a so that the shutter unit 200 can be mounted.

A lower plate 120a is coupled to the lower case 120, and a bill detection sensor 122 capable of detecting whether a banknote is inserted and the position of the banknote is disposed in the space between the lower case 120 and the lower plate 120a. Is installed.

The upper and lower plates 110a and 120a are arranged to be spaced apart at regular intervals while the upper and lower cases 110 and 120 are closed to form a bill transfer path (g (see FIG. 5A)) through which bills are moved. do.

As shown in FIG. 3, the shutter unit 200 is accommodated in an inner space of the upper case 110 to open the banknote transfer path g, and provided in the upper plate 110a. It is installed so as to rotate between the second position protruding through the first and second through holes 111 and 112.

As shown in FIG. 4, the shutter unit 200 preferably includes the first blocking member 210 and the second blocking member 220 arranged in two rows. The first blocking member 210 may have a rounded configuration with respect to the banknote travel direction so that interference with the banknote being passed may be minimized. As such, when the first and second blocking members 210 and 220 are intersected, when the seal or tape is attached to the rear end of the dust cover, the first and second blocking members 200 are closed at the second position where the shutter unit 200 is closed. The second blocking member 210 and 220 and the seal or tape may always interfere.

The driving unit M controls the shutter unit 200 to be rotatable from a first position to a second position, and whether the driving unit M is driven depends on the banknote detection signal of the banknote detecting sensor 122. Is determined accordingly. That is, when a banknote is inserted, the banknote detecting sensor 122 detects whether the banknote passes and whether the banknote is cloaked, and when the rear end of the banknote passes completely through the banknote detecting sensor 122, the banknote transfer path g And pass the bill. Then, the driving unit M drives the shutter unit 200 to be rotatable from the first position in the open position to the second position in the closed position in accordance with a control signal of a predetermined control unit. Banknotes passing through) are prevented from being taken out of the banknote identifying apparatus by an external force such as being pulled by an illegal user. When the banknote detecting sensor 122 detects that a new banknote is inserted, the driving unit M rotates the shutter unit 200 from the closed second position to the first position of the open position, thereby transferring the banknote. Open the furnace (g).

Banknote detection device according to a preferred embodiment of the present invention, it is preferable to further include a detection unit (S) for detecting the position of the shutter unit (200). The sensing unit S may be configured in various ways, but may be provided as a photo sensor having a light emitting unit and a light receiving unit.

As illustrated in FIGS. 5A and 5B, the detection unit S detects the position of the shutter unit 200 through interference with one end of the shutter unit 200. That is, as shown in FIG. 5A, when the shutter unit 200 is in the first position, which is an open position, the shutter unit 200 is configured not to interfere with the end of the shutter unit 200, and the shutter unit 200 is closed. When the position is in the second position, the sensing signal may be output by interfering with the end of the shutter unit 200.

On the other hand, the shutter unit 200 is preferably configured to fall by the weight of the shutter unit 200, instead of receiving a separate power when rotating to move to the second position is a closed position. To this end, the driving unit (M) is preferably provided with a solenoid for fixing the shutter unit 200 in the first position. In addition, although not shown, it is also possible to further install an elastic member such as a torsion spring on the axis of rotation so that the rotational movement to the second position more smoothly. Therefore, when the shutter unit 200 is rotated to the second position according to the detection signal of the banknote detecting sensor 122, the driving unit M releases the restraint of the shutter unit 200 to release the shutter unit. Allow 200 to move to the second position by its own weight.

Hereinafter, the operation of the banknote identification device according to the present invention.

When the banknote is inserted, the inserted banknote is moved along the banknote transfer path g by the first and second banknote transfer units 123 and 124. At this time, the banknote detection sensor 122 detects whether or not the counterfeit of the banknote and the position, and if the inserted banknote is a pneumococcal, the first and second banknote transfer unit 123, 124 continues the bill not shown It is transported to be inserted into the storage box, and when the inserted banknote is counterfeit, the first and second banknote transfer units 123 and 124 reverse, and discharge the inserted counterfeit.

When the inserted banknote is pulmonary, the first and second banknote transfer units 123 and 124 continue to transfer the banknote, and the banknote sensor 122 detects the rear end of the banknote, so that the banknote is a banknote transfer path ( g) Detects complete passage. Then, the predetermined control unit operates the driving unit M to rotate the shutter unit 200 from the first position in the open position to the second position in the closed position.

By the way, when the inserted banknote is puffiness, the thread or tape by the fraudulent user is puffiness connected to the rear end, the first and second blocking members 210 and 220 provided in the shutter unit 200 are attached to the lower frame. It cannot be received through the first and second blocking member receiving grooves 211 and 212 formed through, and interferes with the seal or the tape to completely reach the second position.

Then, since the detection unit S does not output a detection signal due to interference with the end of the shutter unit 200, the controller recognizes that the shutter unit 200 has not reached the second position. In this case, the control unit stops the operations of the first and second banknote transfer units 123 and 124, stops the transfer of the pneumoconiosis, to which a thread or tape is connected, and the shutter unit 200 is configured to perform the first operation. And it is not accommodated in the second blocking member receiving grooves (211, 212), but is fixed to the blocking position close to the closed position, so as to prevent the user from taking out the pneumoconiosis attached to the thread or tape attached to the illegal user .

According to such a configuration, after fraudulent users purchase goods by put-in puffs using a thread or tape, it is possible to block fraudulent acts to recover the put-in puffs again, thereby improving the security of the bill identification device. .
