Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a bill validator mounted on an automatic vending machine or the like, and more particularly to a bill validator cut into several pieces so as not to accept joined bills.

[0002]

2. Description of the Related Art A description will be given with reference to FIG. Conventionally, regarding the arrangement position of the banknote withdrawal prevention lever 1 on the banknote transport path, when the banknote withdrawal prevention lever 1 is one, it is near the longitudinal centerline of the banknote, and when it is two, it is on the longitudinal line that divides the banknote into three equal parts. It was placed near or structurally where it could be attached. Further, the number of the banknote withdrawal prevention levers is limited to three at most.

In contrast to this structure, recently, as shown in FIG. 4, a bill is cut into several pieces in the longitudinal direction in alignment with the central portion of the bill withdrawal prevention lever, and a plurality of places on the bill cutting line 6a are weakly adhesive tape. Insert the banknotes that are joined together by 7, and bond the strong cellophane tape 8 or the like to the tip of the banknote withdrawing direction, output the banknote acceptance signal, and then withdraw both ends that hit the introduction conveyor belt 10, and further the interval between the banknote withdrawal prevention levers. The present situation is that there is a technique for extracting the remaining part by reusing it because it is wide and reconnecting it for reuse. This trick can be easily applied because the banknote pull-out prevention lever 1 has a wide interval and is joined by the adhesive tape 7 having a weak adhesive force.

[0004]

According to the method described above,
The problem is that the bill is accepted as a true bill when the bills are divided into several pieces in the longitudinal direction according to the central portion of the bill withdrawal prevention lever and are joined by an adhesive tape having a weak adhesive force. The present invention has been made in view of the above problems, and its purpose is to prevent bills that are divided into several pieces in the longitudinal direction and are joined by an adhesive tape having a weak adhesive force from being accepted as true bills. To provide an identification device.

[0005]

According to the present invention, the above-mentioned object is to identify a bill including a bill conveying path for conveying inserted bills and a bill discriminating sensor for tracing bills conveyed on the conveying passage. In the apparatus, it is achieved by providing a bill withdrawal prevention lever that appears in and out of the bill transport path on a bill trace line through which a portion of the bill traced by the bill identification sensor passes. The banknote identification sensor includes a magnetic sensor and an optical sensor,
It is good to arrange each bill trace line alternately.

Further, the bill withdrawal prevention lever is
It is effective that the comb is provided in the shape of a comb, and the comb trace is not included.

[0007]

According to the structure of the present invention, since this type of hand cuts the bill in accordance with the bill withdrawal prevention lever,
By providing the banknote withdrawal prevention lever on the banknote trace line, if the banknote identification sensor is a magnetic sensor, the adhesive tape will not detect the generation of magnetism, and the unevenness of the magnetic field due to the step with the adhesive tape will cause it to be unacceptable. The signal of is output. Further, if it is an optical sensor, it transmits light even if it has a small thickness due to the adhesive tape or even a minute gap other than the adhesive tape portion, and outputs an unacceptable signal. Due to this, the joined banknotes are judged to be false banknotes and are returned.

Further, by providing the banknote withdrawal prevention levers other than on the banknote trace line, even if they are received, the banknote withdrawal prevention lever cannot be further easily withdrawn due to the frictional force with the banknote withdrawal prevention lever.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An explanation will be given with reference to FIGS. FIG. 1 is a configuration diagram of an identification unit according to this embodiment, FIG. 2 is an explanatory diagram showing a positional relationship with a bill withdrawal prevention lever, a magnetic sensor or an optical sensor according to this embodiment, and FIG. 3 is a bill withdrawal showing another embodiment. It is explanatory drawing which shows the positional relationship with a prevention lever, a magnetic sensor, or an optical sensor. [Embodiment 1] As shown in FIG. 1, five banknote pullout preventing levers 1 are directly connected to a solenoid 2 and are simultaneously pulled up by the solenoid 2 at the same time when a banknote is inserted. At this point, the banknote transport path 3 is opened and the banknotes are transported by the belts 10 at both ends, and when the leading edge of the banknotes passes the banknote withdrawal prevention lever 1, the banknote withdrawal prevention lever 1 is lowered to the banknote transport path 3 to transfer the banknotes. When the rear end passes, the bill transport path 3 is blocked in the shape of a comb. At this time, when the joined banknotes as shown in FIG. 4 are thrown in, the banknote cutting line 6a is a means for aligning with the central portion of the banknote withdrawal prevention lever 1 as described above (in FIG. 4, banknote withdrawal prevention). The arrow extending the lever 1 and the bill cutting line 6a coincide with each other), and the bill trace line 6 shown in FIG. 2 coincides with the magnetic sensor 4 and the optical sensor 5 alternately arranged on the bill trace line 6. By the operation, the magnetic tape is not detected by the adhesive tape 7 in the magnetic sensor 4 part, and the magnetic variation due to the step with the adhesive tape 7 is generated, and the unacceptable signal is output. Further, in the optical sensor 5 part, a thickness defect due to the adhesive tape 7 or even in a minute gap other than the adhesive tape 7 part, light is transmitted to output an unacceptable signal. As a result, the bill as shown in FIG. 4 is judged to be a false bill and is returned.

Even if the bill cutting line is displaced and the joined bills are accepted, the cellophane 8
In the case of pulling out with, the interval of the bill withdrawal prevention lever 1 is narrower than that of the conventional product, so that the bill piece hits the bill withdrawal prevention lever 1 and is difficult to pull out. Further, if the cellophane 8 moves on the bill trace line 6 during this period, the bill withdrawal prevention lever 1 cannot hit the cellophane 8 and cannot be lowered. . The function of returning the bill as defective is the same as that of the conventional product. [Embodiment 2] FIG. 3 shows another embodiment. Based on the arrangement of the banknote withdrawal prevention lever 1 on the banknote trace line 6, the number of banknote withdrawal prevention levers 1 is increased and the frictional force of the banknotes prevents the banknotes. It is a strengthened prevention of pulling out.

[0011]

According to the present invention, since the bill withdrawal prevention lever is provided on the bill trace line, the joined bills can be judged as false bills and returned as described in the operation section. Even if the connected banknotes are determined to be true banknotes and accepted, it is possible to return the banknotes as defective banknotes and to make it nearly impossible to pull out the banknotes.
