Next, the bill validator 11 will be described. FIG. 1 is a side view of a bill validator according to an embodiment of the present invention, and FIG.
[Fig. 3] is a plan view of the bill discriminating apparatus in the embodiment of the present invention.

In the figure, 11 is a bill validator, 12 is a transport path for transporting deposited or dispensed banknotes (not shown), and 13 is disposed so as to face the transport path 12 to show the thickness of the bill. It is a thickness detecting unit for detecting. The thickness detector 13
Is a bracket 15 which is swingably supported around a shaft 14, and a cylindrical thickness detection roller 1 which is supported by the bracket 15 so as to be rotatable around a shaft 16.
7 and a roller R1 arranged to face the thickness detection roller 17. The brackets 15 are arranged at both ends of the conveyance path 12 in the width direction and support both ends of the thickness detection roller 17. The shaft 14 and the bracket 15 are fixed, and when the shaft 14 is rotated, the bracket 15 is also rotated. Then, a thickness detecting sensor 28 for detecting the thickness of the bill is fixed to the shaft 14. A magnetic sensor can be used as the thickness detecting sensor 28.

Therefore, when a bill passes between the thickness detecting roller 17 and the roller R1, the thickness detecting roller 1
7 is rotated, the bracket 15 is rotated counterclockwise in FIG. 1 by an angle corresponding to the thickness of the bill, and the shaft 14 is also rotated accordingly. As a result, the thickness detection sensor 28 is
The thickness of the bill can be detected based on the rotation amount of 4. The bracket 15 is biased by a biasing means (not shown) toward the side where the thickness detecting roller 17 is pressed against the roller R1.

For example, when the bill is a genuine bill and only one bill, the thickness detecting roller 17 is lifted in the direction of arrow A by the thickness of one bill, and the bracket 15 is rotated by that amount. Then, the thickness detection sensor 28 detects the thickness of the bill based on the rotation amount of the shaft 14 accompanying the rotation of the bracket 15, and sends a detection signal to a control unit (not shown).
Based on the detection signal, the control unit discriminates that the bill has a standard thickness and the bill is a genuine bill.

When the banknote is an unfit banknote and the tape is stuck (has), the corner is broken or missing, the tape sticking part and the bent part are more than normal parts. Get thicker. In this case, the thickness detection roller 17
Is raised further in the direction of arrow A than when the bill is a genuine bill, and the bracket 15 is further rotated. Then, the thickness detection sensor 28 detects the thickness of the bill based on the rotation amount of the shaft 14 accompanying the rotation of the bracket 15, and sends a detection signal to the control unit. Based on the detection signal, the control unit discriminates that the thickness of the bill is not standard and the bill is unfit.

Further, in order to detect the state of the bill, FIG.
Of the magnetic sensor 22 above the thickness detector 13 in
However, a reflection transmission sensor 23 is provided above the magnetic sensor 22.
Are respectively provided as state detecting means. The magnetic sensor 22 is used for printing a bill, and the reflection / transmission sensor 23 detects the magnetic characteristics of magnetic ink, and the reflection / transmission sensor 23 detects the intensity of reflected light, transmitted light, and the like of the bill.

When dust or paper dust or other foreign matter adheres to the outer circumference of the thickness detection roller 17, the rotation angle of the bracket 15 changes by that amount, resulting in a detection error. Therefore, in order to scrape off and remove the foreign matter attached to the outer circumference of the thickness detection roller 17, a scraper 21 is arranged over the entire width of the thickness detection roller 17. Note that in the present embodiment, when the bill is conveyed in both directions along the conveying path 12 and is conveyed downward in FIG. 1, the thickness detection roller 17 is rotated counterclockwise and upward in FIG. Thickness detection roller 17
Is rotated clockwise. Therefore, the scraper 21 is arranged with its tip facing the center of the thickness detection roller 17.

Further, the scraper 21 extends upward from below toward the center of the thickness detecting roller 17, and its tip is brought into contact with the thickness detecting roller 17. Therefore, when the bill is conveyed upward and the thickness detecting roller 17 is rotated clockwise, the foreign matter scraped off by the thickness detecting roller 17 by the scraper 21 moves along the scraper 21 due to gravity. Since it falls, no foreign matter remains on the surface of the thickness detection roller 17. In this case, even if the thickness detection roller 17 is rotated counterclockwise, foreign matter does not enter the space between the roller R1 and the thickness detection roller 17, and therefore the thickness detection sensor 28 is a banknote. The thickness of can be detected correctly.

Further, since the foreign matter removed from the thickness detecting roller 17 by the scraper 21 does not drop and adhere to the magnetic sensor 22 and the reflective / transmissive sensor 23, it is detected by the magnetic sensor 22 and the reflective / transmissive sensor 23. No error will occur. As a result, the denomination of the banknote,
It is possible to correctly discriminate whether it is right or wrong. It should be noted that the rollers R2 and R3 are provided at the upper end of the conveyance path 12 in FIG.
Rollers R6 and R7 are rotatably arranged at the lower end of 2 to convey bills. In this case, the rollers R3, R
5, R7 are urged by urging means (not shown), and are brought into pressure contact with the rollers R2, R4, R6 facing each other.
Further, the rollers R1, R2, R4 and R6 are connected to a motor (not shown) and are rotated by driving the motor.

Next, the operation of the bill validator 11 having the above construction will be described. FIG. 6 is a flowchart showing the operation of the bill discriminating apparatus according to the embodiment of the present invention. In this case, a case where a banknote (not shown) is conveyed from the lower side to the upper side in FIG. 1 on the conveying path 12 (FIG. 1) will be described.

First, when the bill is conveyed to the bill discriminating device 11, the bill is sent to the thickness detecting section 13 by the rollers R6 and R7. Then, the thickness detecting unit 13 detects the thickness of the bill, and a control unit (not shown) determines whether the bill has a standard thickness and discriminates it. At this time, the control unit discriminates the bill as a genuine bill when the thickness of the bill is standard, and discriminates the bill as unfit if it is not standard.

Next, the bill is sent to the magnetic sensor 22, the magnetic characteristics of the bill are detected by the magnetic sensor 22, and then the bill is sent to the reflection / transmission sensor 23. The reflection / transmission sensor 23 irradiates the bill with light. The intensity of the reflected light, transmitted light, etc. of is detected. Then, each detection signal of the magnetic sensor 22 and the reflection / transmission sensor 23 is sent to the control unit. Based on each of the detection signals, the control unit determines whether or not there is a deficiency in the state, shape, etc. of the bill, in addition to the denomination. If not, the bill is identified as a genuine bill.

If the bills are deposited, the bills identified as genuine bills are bill storage boxes 103.
(FIG. 4) or the banknotes identified as unfit banknotes are sent to the escrow unit 104 to the customer service port 106. Also,
When the banknotes are to be dispensed, the banknotes that are identified as genuine notes are sent to the service opening 106, and the banknotes that are identified as unfit notes are sent to the reject banknote storage 109, respectively. Step S1 The control unit determines whether the bill thickness is standard. If the thickness of the bill is standard, the process proceeds to step S2, and if it is not standard, the process proceeds to step S5. Step S2 The control unit determines whether or not the bill is defective. If there is a loss in the bill, the process proceeds to step S5, and if there is no loss, the process proceeds to step S3. In step S3, the bill is identified as a genuine bill. Step S4 The banknote is stored in the banknote storage 103 or the customer service slot 10
Send to 6. In step S5, the bill is identified as an unfit bill. Step S6 The bill is sent to the service opening 106 or the reject bill storage 109.

The present invention is not limited to the above-mentioned embodiments, but can be variously modified within the scope of the present invention, and they are not excluded from the scope of the present invention.
