The present invention is generally related to a banknote-validating machine equipped with security device, and more particularly to a banknote-validating machine equipped with security device having multiple security passes set inside the banknote channel of the banknote receiver capable of substantially preventing the banknote from being pulled out by an external force.
With the advancement of technologies, the vending machines installed in the public places for providing convenience and prompt service to the public, for example, tickets, coin exchange and so on. Vending machines are not only advantageous for cutting down the labor cost but also highly acceptable because of the convenience provided. Generally, the vending machine is unsupervised at most of time except during maintenance or refilling the merchandize supplies therein. During unsupervised period of time, users may try to steal the money within the vending machine. Sometimes, some users may exchange coins or retrieve cards or tickets from the vending machines without actually paying for it. One common way of stealing is to attach a string or attach a soft long strip of film to a distal end of the banknote and then insert the banknote into the banknote entrance slot, and after the transaction of the deal is successful, the user pulls out the banknote by pulling the string or the long strip of film attached to the distal end of the banknote. Accordingly, the stealing activity could cause an unimaginable loss to the vending machines owners.
To prevent the above loss, the conventional banknote-validating machine is equipped with a frame A. Referring to
Accordingly, in the view of the foregoing, the present inventor makes a detailed study of related art to evaluate and consider, and uses years of accumulated experience in this field, and through several experiments, to create a new security device of a banknote-validating machine. The present invention provides an innovated cost effective security device of a banknote-validating machine.
According to an aspect of the present invention, the banknote-validating machine comprises a banknote receiver and a security device installed inside the banknote receiver. The banknote receiver comprises an upper chassis and a lower chassis, and a banknote channel is formed between the upper chassis and the lower chassis. The distal end of the banknote channel is conjoint to the inner part of the banknote entranceon a front panel. A sensor is positioned at a primal end of the banknote channel. A security plate is positioned at the upper chassis. The sensor is adapted for sensing the length of the banknote entering banknote channel and the time taken for the banknote to pass the banknote channel. The security plate is adapted for blocking the banknote. Thus, the security device has multiple security functions for effectively preventing the banknote from being pulled out by an external force.
According to another aspect of the present invention, the sensor installed in the upper chassis is adapted for sensing the length of the banknote, and if the banknote exceeds the standard length, the sensor is capable of issuing a signal for ejecting the banknote out of the banknote entrance slot of the banknote-validating machine.
According to another aspect of the present invention, the security device of the banknote receiver comprises a security plate, which has a plurality of hooks.
According to another aspect of the present invention, the plurality of arrow shaped long and short hooks, and the long and short hooks are arranged alternately.
For a more complete understanding of the present invention, reference will now be made to the following detailed description of preferred embodiments taken in conjunction with the following accompanying drawings.
Reference will be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Referring to
The banknote receiver 2 comprises an upper chassis 21 and a lower chassis 22. A banknote channel 23 is formed between the upper chassis 21 and the lower chassis 22. An upper channel 211 disposed at a lower portion of the upper chassis 21 comprises pluralities of rollers 2111 and sensors 2112. A plurality of moveable buckling plates 212 is disposed at a side of the upper channel 211. A lower channel 221 disposed on a top of the lower chassis 22 comprises a plurality of transporting belt 221land a plurality of buckling holes 222 at a side thereof.
The security device 3 comprises a chassis 31 having a plurality of moveable directing rollers 311. A security plate 32 having a plurality of hooks 321 is set beneath the directing roller 311.
The banknote receiver 2 is conjoined by the upper chassis 21 and the lower chassis 22. The upper channel 211 of the upper chassis 21 and the lower channel 221 of the lower chassis 22 constitute the banknote channel 23. The distal end of the banknote channel 23 is conjoint to the inner part of the banknote entrance slot 11 on the front panel 1. The banknote channel comprises sensor 2112, a circuit layout of which is shown in
When a user attaches a long soft strip of film, for example, an adhesive tape, a thin strip of cardboard, a film, and so on, on the banknote 4 and insert into the banknote channel 23, the aforementioned circuit of the sensor 2112 senses the time taken for the banknote 4 passing the plurality of buckling plate 212 and the buckling holes 222, and if the time for banknote 4 to pass thereof exceed the preset standard value, the circuit of the sensor 2112 issues a signal to reject the banknote 4 and the banknote 4 is ejected out of the banknote entrance slot 11 through the banknote channel 23.
Alternatively, the circuit of the sensor 2112 senses the number of rotation of the roller 2111 while the banknote 4 passes in the banknote channel 23, and if the number of rotations exceeds a preset standard value, the circuit of the sensor 2112 issues a signal to reject the banknote 4 and the banknote is ejected out of the banknote entrance slot 11 through the banknote channel 23.
The security plate 32 of the security device 3 comprises a plurality of hooks 321 arranged in an array comprised of long and short hooks that are alternately arranged. The hooks 321 have an arrow shape. Therefore, the gaps between the hooks 321 are small and therefore the hooks 321 are capable of preventing the banknote 4 being pulled back by any attached objects.

Referring to
Furthermore, if a user glues a plastic or soft strip, or ties a string to one end of the banknote 4, the sensor 2112 is capable of sensing such abnormal situation and reject the banknote 4 and ejects out the banknote 4 out of the banknote receiver 2. In the meantime, the plurality of buckling plates 212 is not released from the buckling holes 222 in order to block the banknote 4. And, when the banknote 4 passes the security plate 32, the attached object will get stuck between the plurality of hooks 321 of the security plate 32, and when the banknote 4 is pulled out by an external force, the hooks 321 cuts off or breaks the attached object. Thus, stealing of the accepted banknote can be effectively prevented.
The aforementioned banknote-validating machine equipped with security device of the present invention has at least the following advantages: i) The banknote channel has the sensor and the plurality of buckling plates alternately positioned with the plurality of buckling holes form the first security pass, and the second security pass of the securing plate ensure the banknote against being pulled out by the external force after the banknote enters the banknote channel.
ii) After the banknote inside the banknote channel of the bank-validating machine pass the plurality of buckling plates and buckling holes moving in a downward direction towards the directing roller, the directing roller forces the banknote to move vertically down and thereby making it increasingly difficult to pull out the banknote by the external force.
iii) The security plate of the security device comprises the plurality of arrow shaped hooks comprised of alternately arranged long-and-short hooks having a small gap therebetween in order to effectively block the banknote.
While the invention has been described in conjunction with a specific best mode, it is to be understood that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations in which fall within the spirit and scope of the included claims. All matters set forth herein or shown in the accompanying drawings are to be interpreted in an illustrative and non-limiting sense.
