The elastic member 7 and the outer wheel 8 can be made next or not. Thereby, when the banknote 3 (sheet) bites between the reference rollers 1a and 1b and the detecting rollers 5a and 5b, the elastic member 7 is deformed to correspond to the thickness of the sheet, and the outer ring 8 is moved upward. . The movement amount is detected by the displacement detecting sensors 9a and 9b, and the detection signals 1 0 a and 1 〇 b corresponding to the thickness of the banknote 3 (sheet) are output. The detection signals 1 〇 a and 1 〇 b are transmitted to the determination processing unit 1 1 . The determination processing unit 1 1 determines whether or not the detection signals are overlapped by the detection signals 1 〇 a and 1 〇 b, and the posture signal 13 of the inclination (the inclination of the conveyance direction) and the displacement (the position in the lateral direction) when the banknote 3 detects the drum. The two or more banknotes 3 are stacked and transported, or whether or not a forged banknote such as a tape is adhered, and the determination signal 12 is output. Further, the posture signal 13 is used to correct the detection signal in the state where the banknote is not tilted, and the position at which the roller is detected in order to obtain the banknote 3. Further, the symbol 4 indicates the tape adhered to the banknote 3. The banknotes 3 are transported in the vertical direction of the paper. Further, Fig. 1 shows that the elastic members do not uniformly contract because the both end portions of the tape 4 pass through the detecting rollers 5a and 5b, so that the detecting rollers 5a and 5b are inclined in the direction of the rotation axis. When in this state, the displacement output of the displacement detecting sensors 9a and 9b forms a smaller ridge than the thickness of the tape 3 in the thickness of the banknote 3. Here, a shift output corresponding to the distance between the center of the detecting portion of the displacement detecting sensor and the outer wheel is formed. In the above description, the reference roller and the detection roller of the two groups are described in -10-(7) 1273516, but the reference roller and the detection roller are arranged in a direction perpendicular to the banknote transport direction so that the banknotes can be detected in a comprehensive manner. . Next, a method of determining the tape to be adhered to the banknote by the processing unit 1 1 will be described with reference to Figs. 2, 3 and 4. Fig. 2 is a view showing the displacement detecting signals 15 and 19 from the displacement detecting sensors 9a and 9b when the forged banknotes to which the tape 4 is pasted pass between the detecting rollers 5a and 5b as shown in Fig. 1. Variety. # In Figure 2, the vertical axis shows the shift output. The horizontal axis shows the moving distance of the banknotes. The output of the banknote portion is indicated by symbols 16 and 20, and the output of the tape portion is indicated by symbols 17 and 21. Moreover, the shift addition signal 23 adds the signal after the shift detection signals 1 5 and 19. Similarly, the output of the banknote portion and the tape portion is indicated by symbols 24 and 25, and the threshold 判定 for the determination process is displayed by symbols 18, 22, and 26. Since the thickness of the banknote varies depending on the location, these thresholds are determined by the data previously recorded in correspondence with the position of the banknote passing through the detecting roller. Then, if the shift detection signals 15 and 19 and the shift addition signal 23 are equal to or greater than the threshold # ,, it is determined that there is tape, and if the threshold is not exceeded, it is determined that there is no tape. 3 is a view showing the thickness of the tape 4 which is obtained by subtracting the thickness of the banknote of each passing position by the detection signal of the displacement detecting sensor for each of the tapes 4 adhered to the banknotes 3 by the position of the detecting roller as shown in FIG. The tape thickness signal 29 is depicted. In Fig. 3, the left and right end portions of the reference cylinder 1a shown in Fig. 1 are indicated by reference numerals 36, 37. Similarly, the left and right ends of the reference cylinder lb are indicated by symbols 38, 39. The tape thickness signal 3 1 shows the thickness of the tape 4 detected by the shift detecting sensor 9a of -11 - (8) 1273516, and the tape thickness signal 3 2 shows the tape 4 detected by the shift detecting sensor 9b. The thickness. Reference numeral 33 is a state in which both ends of the tape 4 are simultaneously multiplied by detecting the inclination of the drum by the position of the detecting rollers 5a and 5b, so that the thickness of the tape 4 to be measured is small. Further, the tape thickness addition signal 30 adds the tape thickness after the tape thickness signals 31 and 32 obtained by the adjacent displacement detecting sensors 9a and 9b. Furthermore, the threshold 处理 for processing is determined by the symbol 34. Then, if the right knee zone thickness signal 31, 32, and the tape thickness addition signal 30 are equal to or greater than the threshold 値34, it is determined that there is tape. If the threshold is less than 値, then it is determined that there is no tape. FIG. 4 shows that the displacement detection is sensed. The shift detection signal of the device subtracts the thickness of the tape thickness signal of the thickness of each banknote passing through the position. In Fig. 4, the tape thickness signal 40 shows a waveform obtained by subtracting the thickness of the banknote of each passing position by the shift detecting signal detected by the shift detecting sensor 9a. The tape thickness signal 4 1 shows a waveform obtained by subtracting the thickness of the banknote at each passing position by the shift detecting signal detected by the shift detecting sensor 9b. Further, the tape thickness detecting signal 42 shows the waveforms of the tape thickness signals 40 and 41 obtained by the adjacent shift detecting sensors 9a and 9b. Symbols 17, 21, and 24 show the waveform of the thickness of the tape portion. Further, the threshold 値 for the determination processing is displayed by reference numeral 34. If the tape thickness signals 40, 41 and the tape thickness detecting signal 42 are equal to or greater than the threshold 値 34, it is judged that there is tape, and if it is less than the threshold ,, it is judged that there is no tape. In the case where the detecting rollers 5a, 5b are tilted as shown in Fig. 1, the output of the shift detecting sensor is lowered, which is obtained by the shift detecting -12-(9) 1273516 sensor as shown in Fig. 2. The shift detection signals i 5 and 19 form a threshold 値 18 or less, and the tape cannot be detected. Similarly, in the tape thickness signals 3 1 and 3 2 shown in Fig. 3, the determination processing threshold 値3 4 or less is formed, and the tape cannot be detected. Similarly, in the tape thickness signals 40 and 4 of Fig. 4, the determination processing threshold 値34 is formed, so that, according to the present invention, the following effects can be obtained: using the addition # is calculated as shown in Fig. 2 When the shift detection signals of the shift detecting signals 15 and 19 obtained by the displacement detecting sensors 9a and 9b are adjacent to each other, the detection signal of the tape portion becomes large, even at the both ends of the tape 4 at the same time. By passing the detection rollers 5a and 5b, the detection roller is tilted, and the tape thickness can be detected. If the tape thickness obtained by the adjacent displacement detecting sensors 9a and 9b as shown in Fig. 3 is added, the thickness of the tape is obtained. When the tape thickness of the signals 31 and 32 is increased by the signal 30, the detection signal of the tape portion becomes large, and even if the both ends of the tape 4 are simultaneously multiplied by the detecting rollers 5a and 5b to tilt the detecting roller, The tape was detected. Further, if the shift addition signal 23 of the tape thickness signals 40 and 41 obtained by the adjacent displacement detecting sensors 9a and 9b as shown in Fig. 4 is used, the detection signal of the tape portion becomes large even if The tape can also be detected by simultaneously passing both ends of the tape 4 through the detecting rollers 5a and 5b so that the detecting roller is inclined. [Embodiment 2] -13- (10) 1273516 Fig. 5 is a view showing another embodiment of the method of determining the tape to be adhered to the banknote by the processing unit. The tape thickness differential signal 43 of Fig. 5 shows the signal after the tape thickness detecting signal 42 of Fig. 4 is differentiated. Symbols 44 and 45 show the threshold 判定 for the determination process. If the absolute value of the tape thickness differential signal 43 is equal to or greater than the threshold 値44 (threshold 値44=absolute 値 of the threshold 値45), it is determined that there is tape, and if it is less than the threshold ,, it is determined that there is no tape. Further, the same result is obtained in the case where the shift addition signal 23 of the mutually adjacent shift detecting signals of Fig. 2 is added. Thus, according to the present invention, it is possible to have an effect of differentiating the thickness of the tape by differentiating the tape thickness detecting signal 42 after the tape thickness signals 40 and 41 obtained by the displacement detecting sensors 9a and 9b are added. In the case of the signal 43, the differential signal of the tape portion is increased, and the tape can be detected even when the both ends of the tape 4 are simultaneously passed through the detecting rollers 5a and 5b to tilt the detecting roller. Further, in the above invention, a method of detecting a tape by adding a signal of the detected mutually adjacent shift detecting signals, adding a signal of a tape thickness adjacent to each other, and a differential signal adjacent to each other is described. The shift detection signal detected by each detection roller, the signal of the displacement detection signal adjacent to the detected adjacent one, the signal of the thickness of the tape adjacent to each other, and the differential signal of the adjacent adjacent addition signal may be added. The result of the determination by both of them is to detect the counterfeit banknote. Further, in the above invention, the description is applied to the case where one shift detecting is used for one detecting roller. The same can be applied to the plural as shown in Fig. 6 - (11) 1273516 Detect the condition of the drum. [Embodiment 3] Fig. 6 is a view showing another embodiment of a sheet thickness detecting device using two shift detecting sensors in one detecting roller. In Fig. 6, the shift detecting sensors 54a, 54b and 54c, 5d are used to measure the displacement of both end portions of the outer ring 523 of the detecting rollers 5 0 a, 5 0 b, except for the thickness of the detecting paper φ sheet. The rest is the same structure as the sheet thickness detecting device of Fig. 1. The detection roller 50a, 5, which is disposed on the detection roller shaft 51, is pressed against the reference roller 1a and 1b, and the detection roller shaft 51 that is driven to rotate, and the detection roller that detects the upward movement of the sheet-like thickness The detecting eddy current shift sensor or the like detects the sensors 54a, 54b and 54c, 5d. The detection rollers 50a and 5Bb have an outer ring 53 formed of a cylindrical member such as metal, and are separated from the detection roller shaft 51 by the other ends of the other wheels 53. Elastic members 52a and 52b. The elastic members 52a, 52b and the outer ring 53 can be made next or not. Thereby, when the sheet is bitten between the reference rollers 1a and 1b and the detecting rollers 50a and 5B1, the elastic members 52a and 52b are deformed to correspond to the thickness of the sheet (banknote), and the outer ring 53 is moved upward. The detection sensors 54a, 54b, 54c, and 54d detect the amount of movement, and output a detection signal 因 detection signal corresponding to the thickness of the sheet to the determination processing unit 55. The determination processing unit 5 determines whether or not the two signals are overlapped by the inclination signal (the inclination of the conveyance direction -15-(12) 1273516) and the displacement (the position in the lateral direction) of the detection signal and the banknote. The above-mentioned banknotes are superimposed and conveyed, or whether or not a forged banknote such as a tape is adhered, and the determination signal 56 is output. Further, the posture signal 56 is used for: correcting the detection signal in a state where the banknote is not tilted, and the position at which the roller is detected in order to obtain the banknote 3. Further, the symbol 4 indicates the tape adhered to the banknote 3. The banknote 3 is conveyed in the vertical direction of the paper surface. Further, Fig. 6 shows a state in which the elastic members do not uniformly contract due to the one end portions of the tape 4 passing through the detecting rolls φ barrels 50a and 50b, so that the detecting rollers 50a and 5ob are inclined in the direction of the rotation axis. When in this state, the displacement outputs of the detecting sensors 54a, 54b and 54c, 54d form a smaller ridge than the thickness of the tape 3 in the thickness of the banknote 3. Here, the displacement output corresponding to the distance between the center of the detecting portion of the displacement detecting sensor and the outer wheel is formed. FIG. 7 shows that the position of the detecting roller shown in FIG. 6 for each of the adhesive tape 4 adhered to the banknote 3 is The thickness of the tape 4, which is subtracted from the detection signal of the displacement detecting sensor, minus the thickness of the banknote passing through each position, is depicted. In Fig. 7, the left and right end portions of the reference roller 1a are indicated by reference numerals 69, 70. Similarly, the left and right end portions of the reference cylinder lb are indicated by reference numerals 71 and 72. The tape thickness signal 6 1 shows the thickness of the tape 4 detected by the displacement detecting sensor 54a. Further, the tape thickness signal 62 shows the thickness of the tape 4 detected by the displacement detecting sensor 54b. The tape thickness signal 63 shows the thickness of the tape 4 detected by the displacement detecting sensor 54c. The tape thickness signal 64 shows the thickness of the tape 4 detected by the displacement detecting sensor 54d. Further, the threshold 値 for the determination processing is displayed by the symbol 59. -16- (13) 1273516 If the tape thickness signals 61, 62, 63, and 64 are equal to or greater than the threshold 値59, it is determined that there is tape. If the threshold 値 is not exceeded, it is determined that there is no tape. Further, the 67-series shows that both ends of the adhesive tape 4 pass through the positions of the detecting rollers 50a and 50b at the same time, and the state in which the thickness of the tape 4 to be measured is small is detected. Moreover, the drum tilt signal 60 is a signal indicating the tilt of the drum. The drum tilt signal 65 subtracts the absolute 値 of the tape thickness signals 6 1 and 62 obtained by the adjacent displacement detecting sensors 54a, 54b to indicate the tilt of the drum. Similarly, the "roller tilt signal 66" subtracts the absolute 値' of the tape thickness signals 63 and 64 obtained by the adjacent shift detecting sensors 54c, 54d to indicate the tilt of the drum. Further, the threshold 値 for the determination processing is displayed by the symbol 68. If the drum tilt signals 6 5 and 6 7 are equal to or greater than the threshold 値 6 8 or more, the tape is judged to have tape because the inclination of the drum is large, and if the threshold 値 is not exceeded, it is determined that there is no tape. Further, the drum tilt addition signal 73 is added to the adjacent drum tilt signal 65 and the drum tilt signal 66. Further, the threshold 用 for the determination processing is displayed by the symbol 74. When the drum tilt addition signal 73 is equal to or greater than the threshold 値 74, the inclination of the S roller is large, so that it is determined that there is a tape, and if it is less than the threshold 则, it is determined that there is no tape. Thus, according to the present invention, the following effects are obtained, and the tape thickness signals 61, 62, 63, 64 and the drum tilt signals 65, 67 are used, even if both ends of the tape 4 pass through the detecting rollers 50a and 50b, The tape can also be detected by detecting the tilt of the drum. Further, if the tape thickness signals 61, 62, 63, 64 are combined with the judgment results of the drum tilt signals -17-(14) 1273516 6 5, 6 7 , even if the tape 4 passes the detection roller, it can The tape was detected. [Embodiment 4] Fig. 8 is a view showing another embodiment of a sheet thickness detecting device. In Fig. 8, the structure is the same as that of the paper sheet of Fig. 1 except that the shift sensor for measuring the displacement of the detecting rollers 5a and 5b is an optical sensor. The shift sensor is composed of a light projecting portion 76, a light receiving portion 78, a light projecting portion 79, and a light receiving portion 81, and is provided to detect a part of the upper portions of the drums 5a and 5b that block the strip rays 77 and 80. The band-shaped light of the light-emitting portion is detected by the light-receiving portion, and the displacement is detected by the amount of received light or the light-receiving position of the light-receiving element arranged in a line shape. Therefore, in the present invention, by detecting the projection light of the detecting roller, the column detects the displacement of the detecting roller to detect the thickness of the sheet. Further, a pair of light projecting portions and a light receiving portion may be sandwiched between the plurality of detecting rollers and arranged to face each other to detect a maximum displacement of the plurality of detecting rollers. As described above, according to the present invention, since the projection light of the detecting roller is detected, the detection output is not lowered even when the detecting roller is tilted, so that the tape can be detected with high precision. [Embodiment 5] Fig. 9 is a view showing another embodiment of a sheet thickness detecting device. In Fig. 9, the structure is the same as that of the paper sheet of Fig. 1 except that the electrostatic capacitance type sensors 85, 86 for detecting the inclination of the rotation axis directions -18 - (15) 1273516 of the rollers 58 and 5b are used. The electrostatic capacitance sensor 8 5 detects the electrostatic capacitance between the electrode 8 8 and the electrode 87. This is because when the detection roller is tilted, the distance between the roller and the electrode is detected to be changed, so that a change in electrostatic capacitance is formed and detection can be performed. According to the present invention, it is possible to detect that the inclination of the drum 0 by detecting the inclination of the drum by detecting the inclination of the drum, and it is possible to determine that the boarding is applied to the tape or the like, so that the belt can be accurately mounted. Tape was detected. Fig. 10 is a view showing an embodiment of a cash automatic processing apparatus for a sheet thickness detecting device of the present invention.
