[0045] 图2是实施方式的纸币鉴别装置11的鉴别处理的流程图。 [0045] FIG 2 is a flowchart illustrating authentication processing of the bill validator 11 of the embodiment.

[0046] 首先,对纸币执行图像传感器处理(Sll)。 [0046] First, the sensor performs image processing on a bill (Sll). 在该图像传感器处理中,例如计算从纸币最初通过图像传感器13的位置到传送路径的端部的距离ΔΧ(参照图4)和纸币的倾斜角度,并转换为校正了纸币的斜率的图像数据。 In the image sensor processing, for example, calculated from the bill initially passed the position of the image sensor 13 to the transport path distance ΔΧ end portion (see FIG. 4) and the tilt angle of the bill, and is converted into corrected image data, the slope of the bill.

[0047] 然后,执行图案匹配处理(S12)。 [0047] Then, the pattern matching process (S12). 在该图案匹配处理中,进行转换后的图像数据、与存储在基准数据存储部15中的作为多个币种纸币的基准的数据的图案匹配,确定一致程度最高的币种。 In the pattern matching process, the image data is converted, and stored in 15 matches the reference data storage unit as a reference denomination banknotes plurality of data patterns, determine the highest degree of coincidence currency.

[0048] 然后,参照存储在基准数据存储部15中的纸币信息表21,获取表示所判定币种的磁图案的记录位置的检测特征信息(S13)。 [0048] Then, 15 refers to the storage in the reference data storage unit in the banknote information table 21, acquires feature information indicating the detection of the position of the recording magnetic pattern currency (S13) is determined.

[0049] 图3是表示纸币信息表21的结构的图。 [0049] FIG. 3 is a diagram showing a structure of a banknote information table 21. 在纸币信息表21中,与每个币种的纸币的状态(朝上、朝下、表面、背面等)相对应地存储着表示纸币的特征信息(磁图案等)的记录位置的检测特征信息。 Detecting feature information stored in the bill information table 21, the state of each banknote denomination (up, down, front and back surfaces, etc.) corresponding to stored characteristic information represents the banknote (magnetic pattern or the like) of the recording position .

[0050] 在纸币信息表21中,例如图3所示存储有以下检测特征信息:Α币种的表面、朝上的状态的特征信息(磁图案等)的记录位置为120mm,B币种的表面、朝下的状态的特征信息的记录位置为65mm。 [0050] In the banknote information table 21 stores, for example as shown in FIG. 3 has the following feature detection information: feature information Α denomination surface, facing upward (magnetic pattern or the like) recording position is 120mm, B denomination recording position information of the feature surface, facing downward is 65mm. 因此,如果确定了纸币的币种、表背面、上下,则可以从纸币信息表21读出相应纸币的检测特征信息。 Thus, if it is determined denomination bills, the front and back, up and down, it is possible to detect feature information of the respective banknotes from the banknote information table 21 is read.

[0051] 然后,转入图2的步骤S14,执行致动器控制处理。 Step [0051] Then, the process proceeds to S14 in FIG. 2, the actuator control process execution. 在该致动器控制处理中,根据从纸币信息表21读出的检测特征信息,控制致动器18,使磁传感器17移动到最适合检测纸币的特征部的位置。 In the actuator control process, based on the detected characteristic information read from the bill information table 21, the control actuator 18, the magnetic sensor 17 is moved to a position most suitable for the detection of the banknote characteristic portion.

[0052] 然后,执行纸币特征部的匹配处理(S15)。 [0052] Then, the matching processing (S15) wherein the banknote portion. 在该匹配处理中,读出存储在基准数据存储部15中的相应币种的特征部的信息(磁图案数据),进行所读出的特征部的信息与磁传感器17的检测数据的图案匹配。 Pattern matching in the matching process, reads out the information stored in the (magnetic pattern data) corresponding to features 15 in the currency reference data storage unit, wherein the magnetic sensor unit of information is read out of the detected data 17 .

[0053] 本实施方式根据鉴别对象的纸币的币种、表背面、上下的状态,使磁传感器17移动到最适合检测纸币的特征部的位置。 [0053] According to the present embodiment of the bill denomination discriminating objects, front and rear surfaces, the upper and lower state, the magnetic sensor 17 is moved to a position most suitable for the detection of the banknote characteristic portion. 由此,始终可以通过磁传感器17检测纸币的特征部,所以不需要存储纸币的整体区域量的、作为图案匹配的基准的数据,可以只将特征部的数据存储在存储器中。 Thereby, always characterized by a magnetic portion sensor 17 detects the bill, the amount of the entire region need not be stored banknotes, as the reference data for pattern matching, the feature can only store data in a memory unit. 具体地讲,对于一种币种,可以只将记录有磁图案等特征信息的部分的数据(把其称为模板)存储在存储器中,所以能够减少存储在存储器中的数据量。 Specifically, for one currency, data can only be recorded with the magnetic portion of the feature information pattern or the like (which is referred to as the template) stored in the memory, it is possible to reduce the amount of data stored in the memory.

[0054] 然后,判定全部传感器处理的结果是否正常(S16)。 [0054] Then, the determination result of processing all the sensors is normal (S16). 在图像传感器13的检测数据与特定纸币的图像数据一致,而且磁传感器17的检测数据与相应纸币的磁图案数据一致时(S16、是),转入步骤S17,作为正常纸币受理。 In the image data of the image sensor 13 of the detection data is consistent with a particular bill, and the detected data coincide with the magnetic sensor 17 and the magnetic pattern data corresponding to the bill (S16, YES), proceeds to step S17, accepted as normal banknotes. 另一方面,在传感器的处理结果即使有一个不正常时(S16、否),转入步骤S18,判定为假的纸币,将该纸币废弃。 On the other hand, when the processing result of the sensor even if there is an abnormal (S16, NO), proceeds to step S18, it is determined that a false bill, the bill discarded.

[0055] 图4是表示纸币的特征部分与磁传感器17的检测位置的关系的图。 [0055] FIG. 4 is a diagram showing the relationship between the position of the characteristic portion of the magnetic sensor 17 detects the bill.

[0056] 纸币鉴别装置11的传送路径的宽度被设计为大于所投入的纸币22的长度方向的最大尺寸。 [0056] The width of the transport path of the bill discriminating apparatus 11 is designed to be larger than the largest dimension of the longitudinal direction of the banknote 22. 因此,所投入的纸币22以倾斜状态在传送路径中传送的情况居多。 Thus, the majority of inserted bill 22 is inclined in a state of the transmission in the transmission path. 例如,可以根据纸币通过图像传感器13的任意两点(A点、B点)的时间差、两点之间的距离L、和传送速度,计算纸币的倾斜角度θ。 For example, according to the bill by the image sensor 13 between any two points (A point, B point) of the time difference, the distance L, and the transmission rate between the two points, calculates the inclination angle of the bill θ. 并且,可以根据纸币22的右侧最初通过图像传感器13的位置,计算把传送路径的侧面作为基准的距离ΔΧ。 Then, the position may be initially by the image sensor 13, the sides of the transport path is calculated as a reference distance in accordance with the right side of the bill 22 ΔΧ.

[0057] 在图像传感器13检测纸币22整体的图像数据后,判定部14校正所检测的图像数据的倾斜角度,并转换为把特定的位置作为原点的图像数据(规一化)。 [0057] After the image sensor 13 detects the entire image data of the bill 22, the inclination angle determination unit 14 corrects the detected image data, and converts the image data of a specific position as the origin (normalized). 并且,与存储在基准数据存储部15中的各个币种的表面、背面、上下的朝向的基准数据进行图案匹配,判定一致程度最高的币种的纸币22。 And, stored in the reference data pattern matching the surface 15 of each denomination stored in the reference data unit, the back surface toward the upper and lower, the highest denomination banknotes determined degree of coincidence 22.

[0058] 鉴别部16在判定部14判定纸币22的币种、表面、背面、上下的朝向后,从纸币信息表21获取表示纸币22的特征部22a的最佳检测位置的检测特征信息。 [0058] After the authentication unit 16 determines denomination determining section, surface, back surface, top and bottom 14 toward the banknote 22, the banknote information table 21 from the acquired feature information indicating the detection of the position of the best detection feature portion 22a of the bill 22. 并且,根据该获取的信息驱动致动器18,使磁传感器17移动。 And, based on the information acquired drives the actuator 18, the magnetic sensor 17 moves. 磁传感器的移动量根据纸币信息表21和距传送路径的侧面的距离ΔΧ计算得到。 Movement of the magnetic sensor is calculated based on the distance from the transmission path ΔΧ 21 and the side surface of the banknote information table.

[0059] 关于具体的动作步骤,如图4所示,比较当前的磁传感器的位置和从纸币信息表得到的基于检测特征信息的位置信息,判定是否应该使磁传感器移动。 [0059] With regard to specific operation steps, to compare the current position and the position of the magnetic sensor based on the detection information obtained from the features of the banknote information table shown in FIG. 4, it is determined whether to move the magnetic sensor. 并且,在判定为应该移动时,使磁传感器完成移动,直到纸币被传送到磁传感器的位置。 Further, when it is determined to be moving, the magnetic sensor is completed movement, until the bill is transferred to the position of the magnetic sensor. 并且,通过磁传感器17 检测纸币22的特征部22a'。 Further, the magnetic sensor 17 is detected by the characteristic portion 22 of the banknote 22a '. 由此,可以根据检测纸币22的币种、表面、背面、上下的状态, 正确检测不同的特征部。 Thus, according to denomination, face, back, upper and lower detection state of the bill 22 correctly detect different features.

[0060] 图5是表示纸币22的特征部22b和模板的结构的图。 [0060] FIG. 5 is a diagram showing a configuration of the feature portion 22b of the bill 22 and templates. 图5㈧表示在纸币22的右侧部分存在特征部(记录有磁图案的部分)22b的示例。 FIG 5㈧ indicates the presence of features (recorded magnetic pattern portion) 22b in the example right portion 22 of the bill.

[0061] 根据由图像传感器13检测的图像数据确定纸币22的币种、背面、表面、上下后,从纸币信息表21获取存在相应纸币22的特征部的检测特征信息。 [0061] The image data is determined by the image sensor 13 detects a banknote denomination, the back surface, the upper and lower, of the features detecting unit acquires the presence information corresponding to the bill from the bill information table 22 in 2122. 并且,根据该检测特征信息,由于磁传感器17是处于初始位置,所以从致动器18的中央向右方向移动,进行纸币的特征部的检测。 And, based on the detected characteristic information, since the magnetic sensor 17 is in an initial position, moves to the right direction from the center of the actuator 18, the banknote detecting section of the feature. 此时,如果纸币22倾斜,则特征部也被检测为相对纸币22倾斜的方向。 At this time, if the bill 22 is inclined, it is also detected as the feature portion 22 is inclined relative to the direction of the bill.

[0062] 因此,从基准数据存储部15读出的模板的数据也按照与纸币的倾斜角度对应的轨迹(图5中虚线所示的轨迹)读出数据,进行该读出的数据与磁传感器17的检测数据的图案匹配。 [0062] Thus, the template 15 from the data readout unit also storing reference data read out in the trace (shown in dashed lines in FIG. 5, track) data is read, the inclination angle with the bill data corresponding to the magnetic sensor 17 is a pattern match detection data.

[0063] 如上所述,通过使磁传感器17沿与传送路径正交的方向移动,可以始终检测纸币的特征部的数据,所以作为图案匹配的基准的模板的数据,只在存储器中存储纸币22正立时的特征部的数据即可。 [0063] As described above, by the magnetic sensor 17 moves in a direction orthogonal to the transport path, wherein the data unit can be always detected bill, the pattern matching reference data as a template, only the banknotes stored in the memory 22 wherein the data portion of the can is immediately. 由此,可以减少存储在存储器中的模板的数据量。 This reduces the amount of template data stored in the memory.

[0064] 根据上述的实施方式,通过图像传感器13确定纸币的币种、表面、背面、上下,获取表示对应于特定条件的纸币的特征部的位置的检测特征信息,根据该检测特征信息移动磁传感器17的位置,从而可以根据纸币的币种在最佳位置进行检测。 [0064] According to the above embodiment, the image sensor 13 is determined by the banknote denomination, face, back, up and down, a detection feature information acquiring positions of the feature portion corresponding to the specific conditions of the bill, based on the movement of the magnetic information detection feature the position sensor 17, which can be detected at the optimum position according to the denomination of the bill. 由此,可以正确检测所有币种的纸币的特征部,所以可以提高纸币的真伪鉴别精度。 Thereby, it is possible to detect the correct feature of all denomination banknote, the authenticity discrimination accuracy can be improved bill.

[0065] (1)本发明不限于纸币,可以适用于需要真伪判定的包括证券等证件类在内的纸张种类。 [0065] (1) The present invention is not limited to banknotes, paper type can be applied to the determination of need for authenticity, including securities and other documents, including the class.

[0066] (2)检测特征信息的传感器不限于磁传感器,也可以是光学传感器等其他传感器。 [0066] The sensor (2) detects characteristic information is not limited to the magnetic sensor, other sensors may be optical sensors.
