BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bill validator used in various automatic vending machines or coin changers,

Particularly, when a user inserts a bill into the bill discriminator through the insertion port and then forcibly returns the bill to the bill discriminator, the bill discriminator itself is prevented from failing or stopping due to fragments of the bill cut by cutting a part of the bill The present invention relates to a device for preventing a forced backward movement of a bill.

2. Description of the Related Art [0002] Generally, in a bill discriminating apparatus incorporated in a vending machine or a coin changer, a bill inserted into the apparatus by a user is usually taken out through banknote discriminating means for discriminating between banknotes and counterfeit banknotes, A predetermined electrical signal is transmitted according to the liquid level of the inputted bill, and the pneumoconiosis is transported to the banknote storage part so that the operator can collect the banknote collectively.

In recent years, as a variety of products, which are generally sold in vending machines and the like, have become increasingly sophisticated, the spread of vending machines that allow the use of paper money has become commonplace.

As a result of the recent development of the paper currency discrimination technology, the illegal act to obtain the effect of pouring money by inputting the counterfeit money by the erroneous operation of the paper currency discrimination part, the pneumatic currency input is normally supplied to the paper currency discrimination part, An illegal act is often performed in which the input bill is forcibly blocked from being conveyed to the banknote storage portion and is forcedly fed back to the input port to obtain the effect of pouring.

The structure of the forced reverse conveyance prevention device of the conventional paper currency discrimination device has a structure in which a latch structure having a mechanical structure in the form of a latch that is allowed to flow in only one direction is provided. This is because when the inputted paper money is forcibly returned, the inputted paper money is torn, the partial cut or the wrinkle is generated, and the other paper money which is circulated in the market is damaged, or the fragments of the partially cut paper money, Resulting in failure or disabling of use.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an automatic vending machine and a coin changing machine, which can prevent a user from illegally taking out an article of a vending machine, The present invention provides a forcible back-and-forth locking device of a bill that can prevent the bill discriminating device itself from being broken or stopped due to fragments of bills.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paper currency discrimination apparatus in which a rotary shutter having a cutting hole formed therein is provided inside an insertion opening of a paper currency discriminator and a cutting hole of the rotary shutter is formed at a position deviating from a rotation center of the rotary shutter by a predetermined distance, So that the passage of the insertion port is opened and closed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

A rotary shutter 4 having an incision hole 5 formed inside an insertion port 12 of a bill identification device 11 is mounted on a hinge shaft 6 as a center, And a position detecting hole 7 is formed on one side of the rotary shutter 4 so that the sensor 9 can detect whether the passage is opened or closed.

At this time, it is preferable that the incision hole 5 is formed in a radial direction at a certain distance from the hinge shaft 6. [

The driving means for rotating the rotary shutter 4 is formed by a pinion 10 connected to the motor by forming a gear 8 on the outer peripheral surface of the rotary shutter 4. [

According to the present invention configured as described above, the cutting hole 5 formed in the rotary shutter 4 is in a state in which it coincides with the passage of the insertion port 12 of the paper currency discriminator 11 when the paper currency is ready for receiving the paper currency.

At this time, when the passage of the incision hole 5 of the rotary shutter 4 and the passage 12 of the insertion port 12 coincide with each other, the position detection hole 7 formed on one side of the rotary shutter 4 is detected by the sensor 9, So as to be able to detect the opening state of the passage.

When the user inserts the banknote into the insertion port 12, the banknote is passed through the cutting hole 5 of the rotary shutter 4 by the belt 1 and the pulleys 2 and 3, It is identified whether it is counterfeit.

At this time, when the banknote is conveyed to the banknote identification sensor through the cutout hole 5 of the rotary shutter 4, the rotation of the motor is transmitted to the pinion 10 as the driving means and the rotary shutter 4, So that the circuit shutter 4 rotates about the hinge shaft 6. [

The rotation of the rotary shutter 4 is performed such that the incision hole 5 formed in the radial direction of the rotary shutter 4 is rotated together with a predetermined interval at the hinge shaft 6 of the rotary shutter 4, 12 and the passage between the banknote identification sensor and the banknote identification sensor are blocked.

Then, when the banknotes are completely identified and the inserted banknote is pneumatic, the inserted banknote is moved to the storage section. After the storage of the banknotes is completed, the rotary shutter 4, which has blocked the passage, The passage between the passage of the insertion port 12 and the paper currency discrimination sensor is opened by the incision hole 5 of the rotary shutter 4 since the detection hole 7 is rotated until it is detected by the sensor 9. [

In addition, even when the inserted bill is identified as a counterfeit, the rotating shutter 4 rotates again as described above to open the passageway and then take out the banknote identified as counterfeit.

Therefore, when the opening and closing of the passage are made while the rotation of the rotary shutter 4 for opening and shutting the passage is rotated only in one direction, a string or the like is connected to the banknote so that the banknote is forcibly returned The strap connected to the banknote is wound around the hinge shaft 6 of the rotation shutter 4 to prevent the banknote from being forcibly fed back.

As described above, the rotation of the rotary shutter 4 having the cut-off hole 5 is not limited to the above-described one-direction but also the effect of opening and blocking the passage of the paper currency insertion port 12 Can be obtained.

As described above, according to the present invention, there is provided a rotary shutter having a cut-out hole formed in the insertion port of the bill identification device, and the cut-out hole of the rotary shutter is formed at a position deviating from a rotation center of the rotary shutter by a predetermined distance, The passage of the insertion port is opened and closed so that the user inserts the banknotes into the unattended vending machine or the cash dispenser and then forcibly returns the inputted banknotes to obtain the effect of pouring the money and prevent the illegal purchase of the goods from the vending machine The bill discriminating apparatus itself can be prevented from failing or stopping due to the fragments of the banknotes which have been cut off and cut off due to the forced return of the banknotes.
