Description of the invention: [Technical field to which the invention pertains] (4) The i-day f is '1 to cause the magnetic sensor to detect the magnetic measurement with the magnetized region and the detection signal emitted by the magnetic sensor. Technology is not known. The magnetic sensor is used, for example, in a discriminating device that discriminates between the authenticity of a banknote or a valuable document (for example, according to the patent document). A magnetic carrier having a magnetized region such as a magnetic ink, such as a securities, is used to make a magnetic sensor's pattern of the magnetic field strength from the magnetized region (hereinafter, the pain wheel is a pattern). The detected pattern of the magnetized regions in the magnetic carriers + is compared with a reference pattern prepared in advance 'by performing the discrimination of the magnetic carrier. In order to detect the pattern of the magnetized region of the magnetic carrier, the magnetic The sensor is disposed in a main array in a direction orthogonal to the traveling direction of the transported magnetic carrier, and is disposed adjacent to each other in a main array shape, and by the plurality of magnetic sensing That is, the magnetic sensor array outputs the magnetic field strength from the magnetized region that is transported at a fixed speed as a detection signal at a fixed time. The detection signal of each time obtained according to this is used for the entire magnetization. The pattern of the area is detected. Here, when the magnetic sensor array is used to output the magnetic field intensity from the magnetized area as a detection signal, the magnetic sensors of the magnetic sensor array are formed, and are taken out and taken from the respective The magnetic region of the positive magnetization region, that is, the output of the positive magnetic field strength minus the magnetic field of 200921563^, is outputted by the side signal. [Patent Document 1] Japanese Patent Laid-Open No. 2006-236198, Μ When using a magnetic sensing array to detect magnetic media, a phenomenon called so-called overlap occurs, that is, each magnetic sensor, two will come! The corresponding magnetic zone corresponding to them The positive measurement of the magnetic field strength will strongly overlap the magnetic field from the magnetic regions around the respective positive magnetic regions because the magnetic field from the magnetized region is extensible due to the expansion of the magnetic field from the magnetized region. It will be detected by the magnetic sensing. Therefore, the magnetic fields from the magnetic domains will not only be opposed to each other::==|j: the magnetic sensor 4/, which is also adjacent to each of the above magnetic sensors. Therefore, as mentioned above, each magnetic sensor will not only detect the positive magnetic field strength of the mirror, but also the strength of the magnetic field around the incoming bet. (3) Each positive magnetic moment is produced. The magnetic sensor array detects the magnetic media because the magnetic field strength of each magnetic region is affected by multiple magnetic sensor sensors including the corresponding positive magnetic field strength and the surrounding from each positive magnetic region. Magnetic =:: Measure 'and take out the wheel signal. The result will be the problem of the reliability of the _ signal output. The magnetic sensor, that is, the isolated magnetic sensor, is regenerated. _Magnetic sense and Imagine that the close-fitting type is 200921563, and the so-called close-contact type magnetic sensing 使用 used in the body is larger in comparison with the so-called close-type magnetic sensing 取 used for taking in the magnetic field, so that it is easily received by the front of the magnetic domain. The influence of the magnetic field caused by the magnetic zone. Moreover, 'the magnetic field is expanded in proportion to the distance from the magnetized region, so the distance between the magnetic sensor and the magnetic carrier is set larger than that of the close-contact type magnetic sensor. The type of magnetic sensor is susceptible to the magnetic field of the magnetic field induced by the magnetic region around the magnetic region. Therefore, when 磁性, using Pw release magnetic sensing II to speculate on the magnetic carrier, the overlap will significantly affect the output signal. Here, for the overlap of the respective magnetic sensors, the adjacent magnetic = scoop magnetic strength 'adjacent in the direction of the arrangement of the magnetic sensing flaws from the magnetic regions of the respective facing magnetic regions is The 'caused by the strength of the adjacent magnetic field' will especially reduce the resolution of the magnetic sensor. Since the magnetic carrier is transported, the magnetic field around each of the magnetic regions in the positive direction of the magnetic region is the magnetic region of the positive magnetic region that will become the non-tilt detector and/or is already The long range of each magnetic sensor = magnetic 11, so the resolution of each magnetic sensor is not significantly reduced due to the overlap from the magnetic regions. On the other hand, the overlap of the adjacent magnetic regions in the magnetic region m: the upwardly adjacent magnetic regions in the magnetic regions around each of the positive magnetic regions will cross the magnetic regions that affect the crying; The detector, therefore, causes each magnetic sensing to affect the overlap caused by the strength of the adjacent magnetic field. 200921563 [Inventive] The object of the present invention is to connect the one-chain method and the Na set, in the use of the close detection == detector array When the magnetized carrier is _, the adjacent J in the direction of the arrangement of the magnetic sensors rings, and the detection signals are output from the respective magnetic sensors. In order to achieve the above object, the detection method of the main nickname of the present invention includes the process of the town (four) sense (4) side information, that is, a plurality of magnetic sensors arranged in an array and adjacently arranged on the disk The traveling direction of the magnetic button having the magnetized region acts in a direction perpendicular to the magnetic carrier. Fresh magnetic pair then 'takes out the output signal corresponding to the strength of the magnetic field and the strength of the adjacent magnetic field from each magnetic sensor by the action, which is from the positive magnetic domain facing each magnetic ,, the adjacency The magnetic field is from an adjacent magnetic zone adjacent to the facing magnetic zone. Then, for each output signal, the correction of the adjacent signal component caused by the adjacent magnetic field strength is performed, and the positive signal component ' caused by the magnetic field strength is output as the detection signal of each magnetic sensor. Further, in order to perform the above-described method of extracting the magnetic sensor detection signal, the magnetic sensor detecting signal detecting device of the present invention has the following features. ', that is, the detecting device of the magnetic sensor 4 includes: a plurality of magnetic sensors 'acting for the magnetic carrier having the magnetized region, and in a direction orthogonal to the traveling direction of the magnetic carrier, Arranged in an array and adjacent to each other; with the 200921563 and the correction mechanism, the output signals of the magnetic sensors are corrected and the debt measurement signals are output. And the plurality of magnetic sensors extract the output signals corresponding to the magnetic field strength and the adjacent magnetic field strength from the magnetic sensors, and the positive magnetic field strength is from the opposite of each magnetic sensor. In the positive magnetic region, the adjacent magnetic field strength is from an adjacent magnetic region adjacent to the positive magnetic region. Further, the correcting means performs correction of the adjacent signal components caused by the adjacent magnetic field strength for each of the output signals, and outputs the positive signal components which are caused by the magnetic field strength as the detecting signals. [Effect of the Invention] The magnetic sensor detecting signal detecting method and the detecting device according to the subject matter of the present invention, by the correcting mechanism, the output signals taken out by the respective magnetic sensors are caused by the adjacent magnetic field strength The adjacent signal component, that is, the correction of the signal component taken out by the overlap from the adjacent magnetic regions. Thereby, the positive signal components caused by the facing magnetic regions are respectively output as the detection signals of the respective magnetic sensors. '" Therefore, in the detection method of the magnetic sensor detecting signal and the detecting device of the subject matter of the present invention, the detecting signal may be output without the adjacent signal component caused by the overlap from the adjacent magnetic regions. Therefore, in the method for detecting a magnetic sensor detecting signal and the detecting device of the subject matter of the present invention, even when an isolated magnetic sensor is used, the resolution of the magnetic sensor caused by the overlap can be suppressed. The reduction.

Further, in each of the drawings, the shape, size, and arrangement relationship of the respective constituent elements are roughly shown to the extent that the present invention can be understood. Therefore, the configuration of the present invention is not limited to any of the illustrated configuration examples. <Embodiment> In the present embodiment, a magnetic sensor for detecting a magnetic carrier using a magnetic sensor array detects a signal.

The magnetic sensor array 21 is operated for every ID time in order to detect the magnetic carrier 13' fixed on the traveling surface 15. And by the respective actions, the output signals corresponding to the detected magnetic fields are taken out from the respective magnetic sensors 17. In the present embodiment, the operation signal detector 17 is transmitted from the drive circuit 22 to each of the magnetic units 17 at a fixed time and operates on the magnetic carrier 13. Preferably, the traveling speed of the magnetic carrier 13 and the respective motion_day intervals are preferably set arbitrarily according to the surface of the hybrid signal as the artifact or the accuracy of the desired detection signal.

The case of sensing n 18a is taken as an example, and a method of calculating the pair of signal components of each of the opposite directions 18a using the equations (1) to (3) will be described. In the configuration example of FIG. 1 and FIG. 2, the magnetic sensor array 21 includes, in order, a sensor 17c (hereinafter also referred to as an ith magnetic sensor 17c) and a magnetic sensing state 17 (1 (hereinafter, Also known as the second magnetic sensor 17d), the magnetic sensor 17e (hereinafter also referred to as the third magnetic sensor 17e) and the magnetic sensor 17f (hereinafter referred to as the fourth magnetic sensor 17f) The first magnetic sensor 17c is the opposite magnetic sensor 18a in the present configuration example. The first one is located at one end of the arrangement direction of the magnetic sensor 17, so the positive signal component is calculated using the above formula (2). That is, the output signal of the 200921563 taken out by the first magnetic sensor 17c is included from The facing signal component of the facing magnetic domain 23c and the adjacent signal component of the magnetic domain 23d which is the adjacent magnetic domain from the magnetic domain 23c are stained by 2, and therefore, the above formula (2) is used and expressed by the following formula (4). Α1 = Βι+αΒ2··· (4) In addition, the second magnetic sensor I7d is located in the magnetic sensor 17e and the nth magnetic sensor, that is, the fourth magnetic sensor in this configuration example. The ith magnetic sensing between the mustard Therefore, the positive signal component is calculated using the above formula (1). That is, the output signal A2 taken out by the second magnetic sensor 17d includes the positive signal component % from the facing magnetic domain 23d and is derived from the magnetic The adjacent magnetic regions 23c of the region 23d, that is, the adjacent signal components 呲 and αΒ3' of the magnetic region 23c and the magnetic region 23e are expressed by the following formula (5) using the above formula (1). ΑρΒβαΒβο^ (5) ★ Moreover, The third magnetic sensor I7e is a first sensor located between the first magnetic sensor 17c and the first and nth magnetic sensors, that is, the fourth magnetic sensor 17f in the present configuration example. The equation (1) calculates the positive signal component. That is, the output signal a3 taken out by the third magnetic sensor 17e includes the facing signal component B3 from the magnetic region 23e facing the positive and the adjacent magnetic region from the magnetic region 23e. The adjacent signal components aB2 and aB4' of the magnetic region 23d and the magnetic region 23f are thus expressed by the following equation (6) using the above equation (1). A3 = B3 + aB2 + aB4 (6) Moreover, the fourth magnetic The sensor i7f is the nth of the opposite magnetic sensors 18a, and is located in the alignment direction of the magnetic sensor 17 and the first magnetic sensing The opposite end of the device 17c, therefore using the above equation (3) to calculate the positive signal component. That is, the output signal VIII extracted by the fourth magnetic sensor nf includes 21 200921563 self-aligned magnetic region 2 3 f The positive signal component B* and the adjacent magnetic region 23e from the magnetic domain 2 3 f, that is, the adjacent signal component αΒ3 of the magnetic region 23e, are expressed by the following equation (7) using the above equation 〇)'. Α4 = Β4+αΒ3 (7) According to the above formulas (4) to (7), Β2 and $ are expressed by the following equations (8) and (9). 22 = [ ( ^-αΑ! ) ( 1-α2) -αΑ3+α2Α4]/ ( ... ( g } 〇(Α3-αΑ4-αΒ2) / (1-α2)...(9) to these formulas ( 8) and (9), the Baguang "乂 and correction coefficient ^ taken out by each of the opposite magnetic sensors 18a can be used to calculate B2 and 匕. And, the calculated B2 and I are substituted into the equation (4). And (7), thereby calculating B! and B4. In the method for detecting a magnetic sensor detecting signal of the embodiment, in order to correct the output signal taken out by each of the magnetic sensors 丨7, Further, in the memory unit 33 of the detecting device, the equations (丨) to (3) are stored in advance. Further, in the processing unit 35, the equations (1) "~(3)' read from the memory unit 33 are read. Using the values of the respective output signals Aj (i is a natural number of 1) taken by the n magnetic sensors 17, that is, the opposite magnetic sensors 18a, the respective pairs of signals are calculated (i is 1 passenger i$n). In the details, the respective round-out signals Ai taken out by the respective magnetic sensors π are identified in the control unit 32. Then, the respective round-out signals of each of the identified magnetic sensors are input. To the memory unit 33. Among the identified output signals, the output signal of the magnetic sensor 17 in the future, that is, the output signal of the opposite magnetic sensor 18a, is input to the equation (1) and the corresponding position of each of the opposite magnetic 22 200921563 sensors 18a. (2) or (3) to calculate the facing signal component Bi. Further, the processing unit 35 will have a magnetic sensor 17 disposed at a position that does not face the magnetic carrier 3, that is, a non-opposing magnetic sense. The rounding signal of the detector 18b is regarded as 0. Further, the detecting device outputs the positive signal component as a detecting signal, for example, using a well-known printer, display, etc. Thus, the magnetic sensor of the present embodiment In the detection method of the detection signal, the correction component 19 provided in the detection device can output only the positive signal component as the detection signal. Moreover, the magnetic sensor of the present embodiment extracts the signal. The debt measuring device is provided with a photo sensor 37. In the method for detecting a magnetic sensor detecting signal of the embodiment, the photo sensor 37 is used to select from the magnetic sensor array 21 and the magnetic carrier 13 η pairs of magnetic sensors 17. As already explained, this In the detecting method of the magnetic sensor detecting signal of the embodiment, in the correcting mechanism 19, each output signal taken out from the opposite magnetic sensor 18a is input to a formula, a formula or a formula corresponding to each position. (3) Therefore, in the present embodiment, the processing unit 35 determines the output signal from each of the magnetic sensors 17 as the output signal from the opposite magnetic sensor 18a and from the non-opposing sensor 18b. Next, the processing unit 35 is caused to recognize the magnetic sensor 17' in the magnetic sensor array 21, which is located at both ends of the alignment magnetic sensor 18a in the direction in which the magnetic sensor π is arranged. That is, the position of the first magnetic sensor and the nth magnetic sensor. Therefore, in the present embodiment, the magnetic carrier 23 200921563 13 ' traveling on the running surface 15 is used to obtain the optical signal from the magnetic carrier 13 by using the light sensor to detect 37 before being detected by the magnetic sensor array 21. This detects the width W of the magnetic carrier 13 in the direction in which the magnetic sensor 17 is arranged. The photo sensor 37 is connected to the correction mechanism 19 via an amplifier circuit 39 and an A/D converter 41. The amplifying circuit 39 amplifies the optical signal acquired by the photo sensor 37 at the same magnification. Further, the purpose of setting the A/D converter 41 is to convert the amplified optical signal into digital data and input it to the correcting mechanism 19. Further, in the present embodiment, the width W of the magnetic carrier 13 detected by the photo sensor 37 is input to the determining portion 36 of the correcting mechanism 19. Thereby, when the discriminating unit 36 detects the traveling magnetic carrier 3 by the magnetic sensor array 2, the respective magnetic sensors 17 are discriminated as opposite magnetic directions with respect to the magnetic carrier 13. The detector 18a and the non-opposing magnetic sensor 18b that is not opposed to the magnetic carrier 13. Next, the processing unit 35 selects n magnetic sensors corresponding to the detected widths from the plurality of magnetic sensors 17 by the information from the discrimination unit %. As a result, in the present embodiment, each of the extracted output signals can be input to the equation (1), the equation (2) or the equation (3) corresponding to the position of each of the opposite magnetic sensors. Here, in the present embodiment, when the magnetic sensor array 21 includes the magnetic sensor 17 that is partially opposed to the magnetic carrier 13, the magnetic sensor 17 is recognized as the opposite magnetic sensing. I8a. Further, when the width W of the magnetic carrier 13 in the arrangement direction of the magnetic sensor 17 is not fixed, the discrimination portion 36 is spaced apart from each other according to the traveling speed 磁性 of the magnetic carrier 13 and the magnetic finger _21. At each operation of the magnetic sensing 24 200921 563 array 21, the processing unit 35 is caused to select 11 magnetic sensors corresponding to the width w of the magnetic carrier 13 at the time of the operation. The photo sensor 37 is, for example, a self-transmissive photosensor, a reflective photosensor, and other well-known photosensors, and uses a photosensor corresponding to the design. In addition, in the configuration example of FIG. 2 and FIG. 2, a transmissive photosensor including a light source 37a and a light receiving unit 37b is provided, and the light source 37a is used to irradiate the magnetic carrier 13, and the light receiving unit 37b is used. The transmitted light from the irradiated magnetic carrier 13 is obtained, and the light receiving surface 37ba is placed facing the traveling surface 15. In the present embodiment, the self-driving circuit transmits an operation signal to the photo sensor 37 every fixed time, whereby the photo sensor 37 operates simultaneously with respect to the magnetic carrier. Preferably, the driving circuit for operating the photo sensor 37 is shared with the above-described driving circuit 22 for operating the magnetic sensor 17. In addition, in each of the drawings, a configuration example in which the magnetic induction state 17 and the photo sensor 37 are operated by the shared drive circuit 22 is shown. Further, in the present embodiment, the configuration (not shown) of the drive circuit may be controlled by the control unit 32. Further, in the present embodiment, in order to accurately detect the width W of the magnetic carrier 13, it is preferable to set the resolution of the photo sensor 37 provided in the detecting device to the resolution of the magnetic sensor 17. At least 2 times or more than 2 times. That is, it is preferable that the magnetic sensor detecting signal of the present embodiment is broken, and the number of light sensors of at least the number of times of the magnetic wave constituting the magnetic sensor array 配置 is arranged. 37. : and = each of the photo sensors 37 is preferably arranged adjacent to the arrangement direction of the magnetic sensor array 21 in a row 25 200921563. In addition, in the configuration example of FIG. 2 and FIG. 2, the arrangement of the number of the light receiving portions 37b of the transmissive photosensor 37 and the number of the magnetic sensors I7 is shown, that is, the resolution of the photo sensor 37 is set to The case of the magnetic sensor 17 is twice as large. Further, a plurality of light sources 37a (not shown) may be disposed corresponding to the light receiving unit 3. According to the magnetic sensor detecting signal detecting method and the detecting device of the present embodiment, the C magnetic sensors 17 facing the magnetic carrier 13 by the correcting mechanism 19, that is, the magnetic sense of each opposite The output signal taken out by the detector 18a performs the correction of the adjacent signal component caused by the adjacent magnetic field strength, that is, the signal component taken out due to the overlap from the adjacent magnetic regions. In this way, the positive video segment caused by the positive magnetic zone can be separately output as the detection signal received by each axis sensor. Therefore, in the method for detecting the detection signal of the magnetic sensor of the present embodiment and the side device, the side signal may be output without the adjacent signal component due to the overlap from the adjacent magnetic regions. Therefore, in the side method and the detecting device for the signal sensor of the magnetic sensor of the present embodiment, even when the isolated magnetic sensor is used, the resolution of each of the magnetic sensors 17 caused by the overlap can be suppressed. The reduction. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of this application is subject to the definition of the scope of the patent application. 26 200921563 [Simple description of the schema]
