Field of the Invention The present invention relates to a coin processing apparatus and a plurality of coin processing apparatuses, which are mounted on, for example, an automatic cash transaction apparatus installed in a financial institution such as a bank and automatically perform coin deposit and withdrawal processing. The present invention relates to a coin processing system provided with the above coin processing device.

[0002]

2. Description of the Related Art A financial institution such as a bank is provided with an automatic cash transaction apparatus for handling cash such as coins and bills. This automatic cash transaction apparatus incorporates a circulating coin processing apparatus that automatically performs coin deposit and withdrawal processing.

At the time of deposit, the coin processing device accepts the deposited coin, identifies its authenticity and denomination, and stores the genuine coins among the deposited coins in the corresponding denomination safes according to the identification result. , Fake coins will be rejected. At the time of withdrawal, the required number of coins of the required denomination are taken out from the respective denomination safes, and the number of coins is discriminated after identifying the authenticity or the denomination.

[0004] The inspection unit for identifying the authenticity and denomination of the deposited and dispensed coins includes a diameter sensor and a material sensor for physically detecting the outer diameter and material of the coin, and irradiating light to the surface of the coin. It has an image sensor that optically detects the pattern on the coin surface from the reflected light. The image sensor includes a transport surface made of a transparent glass member, an LED for irradiating light to coins transported on the transport surface from below the transport surface, and a reflected light from the coin below the transport surface. Area CCD
(Charge-coupled device).

[0005] Since coins are circular and rotate 360 °,
It is difficult to specify the position. Therefore, the area where the coin image is captured is specified from all the image data captured by the area CCD (hereinafter, referred to as ticket cutting), and then this area is divided into annular areas having a predetermined width of about 1 mm. Then, an integrated value of density is obtained by binarizing the image data in each divided area. Then, the similarity is obtained by comparing the function (distribution) of the density integral value of each annular area with each of the genuine data stored in advance, and when the similarity is equal to or more than a predetermined value, the detected similarity is detected. The coin is determined to be genuine.

[0006]

In the above-mentioned conventional coin processing apparatus, the processing of discriminating coins is often performed by physical quantity sensors such as a diameter sensor and a material sensor.

The light emitted from the coin is blocked by the coin C, and a light / dark signal due to the shadow of the coin generated at that time is detected by the line sensor 47. Then, by comparing the maximum value of the sensor output with a diameter detection table as shown in FIG. 5B stored in advance in the ROM of the control unit, the outer diameter of the coin C is determined and the denomination of the coin is determined. Is done.

Here, similarly to the material sensor 60, in the diameter detection table data for each denomination, as shown in FIG. In this case, for example, a range of 0.2 above and below is set as the loss area B. When the maximum value of the detected sensor output is located in the genuine coin area A of a certain denomination, it is determined that the coin C is a genuine coin with respect to the diameter, and the coin C is located in the coin loss area B. In this case, it is determined that the coin C is a bad coin with respect to the diameter. When the maximum value of the sensor output deviates from both the true coin area A and the bad coin area B, it is identified that the coin C does not correspond to any denomination with respect to the diameter.

The guide member 5 is detected by the diameter sensor 40.

When the image data of the coin C is stored in the RAM 92b, the CPU 90b specifies an image area corresponding to the coin C from all the image data stored in the RAM 92b (performs a so-called ticket cutting process). Next, by binarizing the image data of the specified image area,
The feature amount of the image is extracted. These image processing are performed by DSP
This is performed by a high-speed arithmetic processing by 99.

When the characteristic amount is extracted, the CPU 90b
By comparing the extracted feature amount with the determination reference data stored in the ROM 91b in advance,
Judgment of the authenticity, correctness, type, and dirt of the coin C is performed.

That is, generally, the coin C is circular,
Rotate 360 degrees. Therefore, it is difficult to specify the direction of the pattern. Also, when performing image processing, coin C
In consideration of the rotation, the processing time becomes impractical (response is delayed).

Therefore, it is necessary to extract a characteristic amount irrelevant to the rotation of the coin C. In other words, from the entire image data captured by the area CCD 33, the area where the image of the coin C is captured is specified (so-called ticket cutting processing is performed), and the specified area is defined as a circular area having a predetermined width (for example, about 1 mm). The image data is binarized at a predetermined threshold in each annular area, and an integrated value of density (high-level integrated value) is obtained. Next, the similarity Rk between the distribution of the density integrated value in these all annular areas and the distribution data of genuine coins of each denomination (reference distribution pattern as reference value data) stored in the ROM 91b in advance will be described below. It is calculated by the following equation.

Similarity (Rk) = {(Ai × Bi)}
/ {Ai × {Bi} where Ai indicates the density distribution of genuine coins and Bi indicates the density distribution of the detected coins.

When the similarity Rk is equal to or more than a predetermined value (for example, Rk ≧ 0.92) (first reference value), the CPU 90b determines that the coin is a genuine coin and the similarity Rk is 0.9 <Rk <0. .9
If it is within the range of 2, it is determined that it is a damaged coin.

When the calculated similarity Rk is lower than 0.9 (second reference value) (0.9> Rk), the image sensor 40 detects the dirt on the coin C. That is, C
When the following requirements are satisfied, the PU 90b recognizes that the coin C is genuine but dirty. 1) The similarity of each of the annular areas of the coin C is obtained from the captured image data, and the similarity of the other annular areas is high except for a specific one to several annular areas. 2) The entire coin C Is high, but the level of the sensor output is less than or equal to a predetermined level as a whole. Inspection unit 7 determines the value of the coin as follows in accordance with the detection result of each of sensors 60, 40, and 30 described above. Determines whether it is true or false. As shown in FIG. 9, first, the material, diameter, and pattern of the coin are detected by the material sensor 60, the diameter sensor 40, and the image sensor 60 based on the above-described processing (ST1, 2).

Subsequently, the pattern similarity Rk of the coin obtained from the pattern detection result is compared with a set genuine reference value 0.92 (ST3), and if Rk ≧ 0.92,
It is determined whether or not the detection result of the material and the diameter is within the genuine coin area A (ST4). If the detection result of the material and diameter is within the genuine coin area A, it is determined that the detected coin is a genuine coin (S
T5).

In step 4, if the detection result of the material and diameter is not in the genuine coin area A, it is further determined whether or not the detection result is in the loss area B (ST6). If the coin is in the coin area B, it is determined that the detected coin is an abnormal physical quantity coin (ST7). If the detection result of the material and the diameter is not in the damaged area B, it is determined that the detected coin is a fake coin (reject coin) (ST8).

On the other hand, when the similarity of the pattern is Rk <0.92 in step 3, the similarity Rk is compared with the set loss reference value 0.9 (ST9), and when Rk ≧ 0.9. In some cases, it is determined whether the detection result of the material and the diameter is in any of the genuine coin area A and the loss coin area B (ST).
10). Then, when the detection result of the material and the diameter is in either the genuine coin area A or the damaged coin area B, it is determined that the detected coin is a pattern abnormal coin (ST11).

In step 9, if the detected pattern similarity Rk of the coin is lower than the set loss reference value 0.9 (Rk <0.9), in the present embodiment, the coin Dirt detection is performed (ST12). Then, it is determined whether or not the detection result corresponds to any of the requirements 1) and 2) described above (ST13). If so, it is determined that the detected coin is a dirty coin (ST14). If none of the requirements 1) and 2), the detected coin is determined to be a fake coin (ST8).
