Description

  The present invention relates to a bill recognition device mounted on a vending machine or the like, and more particularly to a bill recognition device that can identify both wide bills and narrow bills.

  Hereinafter, the banknote identification apparatus 1 which can identify both the conventional wide banknote and a narrow banknote is demonstrated. As shown in FIG. 11, the conventional banknote recognition apparatus 1 includes an insertion port 2 into which a banknote is inserted, a passage 3 connected to the insertion port 2, and an inlet provided on the insertion port 2 side of the passage 3. A sensor 4, a conveying means 5 provided in the passage 3 downstream of the inlet sensor 4, an identification sensor 6 provided in the passage 3, an identification sensor 7 connected to the inlet sensor 4 and the identification sensor 6, The passage width variable means 8 provided on the side surface of the passage 3 and a stacker 9 rolled to the outlet of the passage 3 were included.

  The operation of the bill identifying apparatus 1 configured as described above will be described below. This banknote identification apparatus 1 can identify both banknotes of the narrow banknote 10 shown in FIG. 12A and the wide banknote 11 shown in FIG. The narrow banknote 10 has a width 10a of about 69 mm and a length 10b of about 143 mm. The wide banknote 11 has a width 11a of about 77 mm and a length 11b of about 151 mm.

  Any one of these bills 10 or 11 is inserted from the insertion slot 2. The banknote 10 or 11 inserted from the insertion slot 2 is detected by the inlet sensor 4 shown in FIG. Therefore, the entrance sensor 4 is composed of two banknote detection sensors 4a mounted in the vicinity of both side surfaces of the passage 3, and two banknote insertion sensors 4b mounted inside the banknote detection sensor 4a.

  When the wide banknote 11 is inserted, a total of four signals are obtained from both the banknote detection sensor 4a and the banknote insertion sensor 4b. When the narrow banknote 10 is inserted, either the two signals from the banknote insertion sensor 4b or the two signals from the banknote insertion sensor 4b and the banknote detection sensor 4a depending on the insertion position of the narrow banknote 10 An output is obtained from one sensor, and a total of three signals are obtained. That is, when the wide banknote 11 is inserted, 4 signals are obtained from the entrance sensor 4, and when the narrow banknote 10 is inserted, 3 signals or 2 signals are obtained from the entrance sensor 4. .

  In this way, the type of the banknotes 10 and 11 inserted from the insertion slot 2 is determined. If the kind of banknote 10 and 11 is determined, the width | variety of the channel | path 3 will be varied by the channel width variable means 8 so that the width 10a, 11a of this banknote 10 and 11 may be matched. That is, when the narrow banknote 10 is inserted, the movable walls 8a and 8b move inward, and the passage 3 becomes a narrow passage 3a as shown by a dotted line. When the wide banknote 11 is inserted, the movable walls 8a and 8b do not move and become a wide passage 3b as shown by a solid line.

  After the width of the passage 3 is controlled based on the difference in the types of the bills 10 and 11 inserted from the insertion slot 2, the transport roller 5a constituting the transport means 5 is driven to change the bill 10 or 11 into FIG. To the direction of the identification sensor 6 shown in FIG. In the identification sensor 6, the passages 3a and 3b having different widths are conveyed due to the difference in the types of the banknotes 10 and 11, so the positions in the width direction of the banknotes 10 and 11 are fixed. Therefore, even if the widths 10a and 11a of the banknotes 10 and 11 are different, it is possible to accurately detect banknote feature information at a predetermined specific position.

  Based on the banknote characteristic information output from the identification sensor 6, the authenticator 7 identifies the authenticity and type of the banknotes 10 and 11. The identified banknotes 10 and 11 are stacked and stored in the stacker 9.

As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

  However, in such a conventional banknote identification device 1, the inserted banknotes 10 and 11 detect the banknote width by the entrance sensor 4, and variably control the path width by the path width variable means 8 according to the banknote width. Thereafter, the bills 10 or 11 are transported for the first time by the transport roller 5a.

  That is, as shown in FIG. 14, when the banknotes 10 and 11 are inserted, it takes time 12 to detect the types of the banknotes 10 and 11, and if the inserted banknote is the narrow banknote 10, the movable wall 8a. The banknotes 10 and 11 are transported by the transport means 5 for the first time after switching to the narrow passage 3a taking time 13 until the time 8 is moved.

  As described above, the insertion of the narrow banknote 10 has a time (about 400 msec) during which the conveyance is stopped after the insertion of the narrow banknote 10 until it is conveyed, which is uncomfortable for the operator. It was.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bill discriminating apparatus that solves this problem and realizes bill insertion without any sense of incongruity.

In order to achieve this object, the banknote recognition apparatus of the present invention includes an insertion slot into which a banknote is inserted, a passage connected to the insertion opening, an inlet sensor provided on the insertion opening side of the passage, Conveying means provided in the passage on the downstream side of the inlet sensor, an identification sensor provided in the passage, an identification unit connected to the inlet sensor and the identification sensor, and a variable passage width provided on the side of the passage Means for detecting a banknote width by the inlet sensor and the identification unit during conveyance of the banknote inserted from the insertion slot, and using the path width variable means to match the banknote width, Then, the banknote is identified by the identification sensor and the identification unit, and the transport speed of the transport means is a slower transport speed when the banknote width is detected than when the banknote is identified . Thereby, the intended purpose can be achieved.

According to the present invention, the bill width is detected during the conveyance of the bill inserted from the insertion slot, and the passage width is matched with the bill width using the passage width varying means. Since the banknote width is detected and the passage width is varied, the banknotes can be continuously drawn, and there is no sense of incongruity when the banknotes are inserted. Further, the conveying speed of the conveying means is a slower conveying speed at the time of bill width detection than at the time of banknote identification, and the passage width changing means can switch the passage width at a short conveying distance, and the insertion direction of the banknote recognition device Therefore, the bill identifying device can be made thin.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a banknote recognition device 21 according to an embodiment of the present invention. In FIG. 1, 22 is a housing formed of resin, and a protruding portion 22a is formed on the upper side surface of the housing 22, and banknotes 10 and 11 (see FIG. 12) are formed on the protruding portion 22a. ) Is inserted.

  A passage 24 for the banknotes 10 and 11 is connected to the insertion port 23. An entrance sensor 27 composed of a light emitting diode 25 and a light receiving transistor 26 is mounted near the insertion port 23 of the passage 24.

  The inlet sensor 27 includes four inlet sensors 27a, 27b, 27c, and 27d (not shown). That is, the entrance sensor 27a includes a light emitting diode 25a and a light receiving transistor 26a facing the light emitting diode 25a.

  Similarly, the entrance sensor 27b includes a light emitting diode 25b and a light receiving transistor 26b facing the light emitting diode 25b. The entrance sensor 27c includes a light emitting diode 25c and a light receiving transistor 26c facing the light emitting diode 25c. Has been. The entrance sensor 27d includes a light emitting diode 25d and a light receiving transistor 26d facing the light emitting diode 25d.

  As shown in FIG. 2, the inlet sensors 27a and 27d of the inlet sensor 27 are mounted in the vicinity of both sides of the passage 24. When the wide banknote 11 is inserted, the inlet sensors 27a and 27d An output signal is output. The inlet sensors 27b and 27c are mounted near the center of the passage 24, and when the narrow banknote 10 and the wide banknote 11 are inserted, output signals are output from the inlet sensors 27b and 27c. Depending on the insertion position of the narrow banknote 10, an output signal from the entrance sensor 27a or 27d may be output.

  A dimension 27e between the inlet sensors 27a and 27d is 72 mm, and a dimension 27f between the inlet sensors 27b and 27c is 64 mm. These dimensions 27e and 27f are both equally distributed from the center of the passage 24.

  Referring back to FIG. 1, the pulleys 28a, 28b, and 28c arranged in a triangular shape downstream of the inlet sensor 27, the conveyor belt 29 suspended on the pulleys 28a, 28b, and 28c, and the pulleys 28a, 28b, The conveyance means 31 of the banknotes 10 and 11 is formed with the rollers 30a, 30b, and 30c provided facing 28c.

  Here, the pressing force of the roller 30a is weaker than that of the other rollers 30b and 30c to weaken the bill holding force. Thus, it is important to weaken the banknote holding force of the transport means 31 in the vicinity of the entrance sensor 27 in order to align the banknotes while transporting.

  Along the conveying means 31, a passage width varying means 32 for varying the width of the passage 24 is provided. This passage width varying means 32 has a function of making passages 24 (24a, 24b) that match the respective bills 10, 11 based on the width of the bills 10, 11 inserted into the insertion slot 23.

  FIG. 2A is a plan view of the vicinity of the insertion slot 23 when the wide banknote 11 is inserted into the insertion slot 23. When the wide banknote 11 is inserted, output signals are obtained from all the four entrance sensors 27 (27a, 27b, 27c, 27d). In this case, the movable walls 33a and 33b constituting the passage width varying means 32 do not move and have the same passage width as the passage 24 in the vicinity of the insertion port 23. That is, the wide passage 24a is formed.

  FIG. 2B is a plan view of the vicinity of the insertion slot 23 when the narrow banknote 10 is inserted into the insertion slot 23. When the narrow banknote 10 is inserted, output is obtained from the two inlet sensors 27 (27b, 27c). In this case, the movable walls 33a and 33b constituting the passage width varying means 32 move in the direction of the arrow 32a, and the passage width is narrower than the passage 24 in the vicinity of the insertion port 23. That is, the narrow passage 24b is formed.

  FIG. 3 is an operation explanatory view of the passage width varying means 32. Crank-shaped cam grooves 34a and 34b are formed in the movable walls 33a and 33b, and the slider 35 in which a pin 35a is implanted slides in the cam grooves 34a and 34b. A slider groove 35b is formed in the center of the slider 35, and a pin 36a implanted in the gear 36 slides in the slider groove 35b. The gear 36 is connected to a variable passage width motor 37 (not shown). Accordingly, the movable walls 33a and 33b move each time the gear 36 is rotated halfway by the rotation of the passage width variable motor 37, so that the wide passage 24a or the narrow passage 24b is formed.

  FIG. 3A shows an example in which the narrow passage 24b is formed by the movable walls 33a and 33b. FIG. 3B shows a state in which the gear 36 is rotated halfway in the direction of the arrow 32b from the state of the narrow passage 24b. In this example, the wide walls 24a are formed by expanding the movable walls 33a and 33b.

  FIG. 4 is a cross-sectional view when the passage width varying means 32 is controlled to form the wide passage 24a and the narrow passage 24b. FIG. 4A shows an example in which the wide walls 24a are formed by moving the movable walls 33a and 33b to the outside. FIG. 4B shows the movable walls 33a and 33b from the state of the wide passage 24a. This is an example in which the narrow passage 24b is formed by moving inward.

  As described above, the inserted banknotes 10 and 11 are conveyed by the conveying means 31 while the passage width is varied by the passage width varying means 32. The passage 24 where the width of the banknotes 10 and 11 is detected by the entrance sensor 27 is used as a banknote width detection area.

  Returning to FIG. 1, the direction of the passage 24 and the conveying means 31 is changed approximately 90 degrees by the pulley 28b. An identification sensor 41 is provided on the wall in the middle of the passage 24 between the pulley 28b and the pulley 28c whose directions are changed. The identification sensor 41 includes a light emitting diode 42 and a light receiving diode 43 provided to face the light emitting diode 42.

  The output of the identification sensor 41 is connected to the identification unit 45. The identification unit 45 identifies the authenticity and type of the inserted bills 10 and 11. As a result of the identification, in the case of a fake banknote, the conveying means 31 is reversed and the inserted banknote is returned to the insertion slot 23. In the case of true banknotes 10 and 11, the transport means 31 is rotated forward, transported to the stacker 46, and stored in the stacker 46.

  FIG. 5 is a block diagram of the banknote recognition device 21 centering on the electric circuit of the banknote recognition device 21. An entrance sensor 27 including a light emitting diode 25 and a light receiving diode 26 is attached to the passage 24 near the insertion slot 23 into which the bills 10 and 11 are inserted. The light emitting diode 25 is connected to the output of the control circuit 51. The light receiving diode 26 provided opposite to the light emitting diode 25 is connected to the identification circuit 52.

  A transport unit 31 is provided downstream of the inlet sensor 27, and the transport unit 31 is driven by a transport motor 53. The transport motor 53 is driven by a motor drive circuit 53 a connected to the control circuit 51.

  An identification sensor 41 composed of a light emitting diode 42 and a light receiving diode 43 is provided in the passage 24 on the downstream side of the inlet sensor 27 with the passage 24 interposed therebetween. The light emitting diode 42 is connected to the control circuit 51 and controlled.

  The output of the light receiving diode 43 is connected to the identification circuit 52 through a logarithmic amplifier 55, a linear amplifier 56, and an AD converter 57 in this order. The identification circuit 52 is connected to a memory 58 in which a reference value for identifying banknotes is stored.

  The detection data of the banknotes 10 and 11 detected by the light receiving diode 43 are amplified by the logarithmic amplifier 55 and the linear amplifier 56, converted into digital data by the AD converter 57, and compared with the reference value stored in the memory 58. Thus, the authenticity and type of the banknotes 10 and 11 are identified. The identification result is output from an output terminal 59 connected to the identification circuit 52. The identification circuit 52 and the control circuit 51 are also connected to each other, and the control circuit 51 controls based on the identification result output from the identification circuit 52. Here, the logarithmic amplifier 55, the linear amplifier 56, the AD converter 57, the identification circuit 52, and the memory 58 form the identification unit 45.

  The output of the control circuit 51 is connected to the variable path width motor 37 via the motor drive circuit 37a. The variable passage width motor 37 is mechanically connected to the movable walls 33a and 33b via a gear 36. Accordingly, the movable walls 33 a and 33 b are controlled by the control circuit 51 based on the output signal output from the input sensor 27.

  The operation of the bill validator 21 configured as described above will be described below with reference to FIG. First, when the banknotes 10 and 11 are inserted into the insertion slot 23, in step 61, the entrance sensor 27 works to detect the insertion of the banknotes 10 and 11. When the banknotes 10 and 11 are detected, the process proceeds to step 62 and the inserted banknotes 10 and 11 are transported at a low speed (80 mm / sec) by the transport means 31.

When the bill is transported by about 10 mm, the process proceeds to step 63 where the number of output signals from the inlet sensor 27 is detected again. The process proceeds to step 64 when detecting the number of output signals of the input mouth sensor 27. If the output of the entrance sensor 27 is 3 or less, it is determined that the inserted banknote is a narrow banknote 10. Then, the process proceeds to step 65, where the passage width varying means 32 is operated to make the passage width the narrow passage 24b.

  After the passage width is switched to the narrow passage 24b, the process proceeds to step 66, where the conveying means 31 is set to high speed conveyance (150 mm / sec). If it is determined in step 64 that the banknote 11 is wide, the process proceeds directly to step 66 and is conveyed at high speed.

  Next, the process proceeds to step 67 where the authenticity and denomination of the banknotes 10 and 11 are identified by the identification sensor 41 and the identification unit 45. Next, the process proceeds to step 68, and if it is determined that the banknote is a true banknote, the process proceeds to step 69, and a banknote type signal is output from the output terminal 59. Then, the process proceeds to step 70, and the banknotes 10 and 11 identified as true banknotes are conveyed to the stacker 46 and stacked and stored in the stacker 46.

  Then, the process proceeds to step 71. In step 71, if the width of the passage 24 is the narrow passage 24b, the routine proceeds to step 72. In step 72, the passage width varying means 32 is operated to turn the passage 24 into the wide passage 24a, and the process ends. If the wide passage 24a has already been reached in step 71, the process ends.

  In step 68, if the inserted banknote is a false banknote, the process proceeds to step 73, and the false banknote reverses the conveying means 31 and returns it to the insertion slot 23. Then, the process proceeds to step 71. In any case, the passage 24 becomes a wide passage 24a at the end stage.

  FIG. 7 is a timing chart of the transport motor 53 constituting the transport unit 31. FIG. 7A is a timing chart when the passage width needs to be switched. That is, when the entrance sensor 27 detects the bills 10 and 11 at the time 75, the transport motor 53 is pulse-driven 74a. By carrying out pulse drive 74a of conveyance motor 53, conveyance speed is conveyed at low speed. By controlling this pulse width, the number of rotations of the transport motor 53 driven by DC power is controlled. The conveyance speed is controlled by changing the pulse width. Thus, since the rotation speed is controlled by the pulse width, the control is easy and a low-cost control means can be realized.

  After the banknote is controlled by the inlet sensor 27, the number of output signals from the inlet sensor 27 is detected again at a time point 76 when the banknote is conveyed about 10 mm. Here, when it is determined that the banknote 10 is narrow, the passage width varying means 32 operates to make the banknote passage 24 a narrow passage 24b. Reference numeral 77 denotes an operation time of the passage width varying means 32. The low-speed conveyance is continued during the time 77 of this operation, and when a predetermined time 78 elapses, a DC voltage (pulse width 100%) 74b is supplied to the conveyance motor 53. By the supply of the DC voltage 74b, the transport means 31 becomes high-speed transport. The banknote 10 is identified in the middle of this high-speed conveyance.

  FIG. 7B is a timing chart when the wide banknote 11 is inserted. When a banknote is detected by the entrance sensor 27 at the time 75, the transport motor 53 is pulse-driven 74a to transport at low speed. Then, at the time point 76 when the bill is conveyed about 10 mm, the number of output signals of the inlet sensor 27 is detected again. Here, since it is determined that the banknote 11 is wide, the passage width varying means 32 does not operate and the wide passage 24a remains. In this case, when a predetermined time 79 elapses, a DC voltage (pulse width 100%) 74b is supplied to the transport motor 53, and the transport means 31 performs high-speed transport. The banknote 10 is identified in the middle of this high-speed conveyance.

  As mentioned above, since the conveyance motor 53 rotates continuously from the time of detecting the banknotes 10 and 11 with the entrance sensor 27, the banknotes 10 and 11 are continuously conveyed. That is, the width of the banknotes 10 and 11 is detected during conveyance, and the width of the passage 24 is switched to the wide passage 24a or the narrow passage 24b. Therefore, even if the banknote inserted is the narrow banknote 10 or the wide banknote 11, it will be drawn continuously, and there is no sense of incongruity at the time of banknote insertion.

Moreover, since the detection of the banknotes 10 and 11 and the operation | movement of the passage width change means 32 are conveyed at low speed, a passage width can be switched by a short conveyance distance. Therefore, it is the this to narrow the width of the insertion direction of the bill validator 21 (depth direction), and thin in the bill validator 21.

  Further, by detecting the time detected by the entrance sensor 27 twice at a predetermined time interval, the insertion detection of the banknotes 10 and 11 and the detection of the banknote width are performed together. Therefore, a low-cost entrance sensor 27 can be realized.

  Furthermore, since the pressing force (banknote holding force) of the roller 30a on the inlet sensor 27 side that constitutes the conveying means 31 is weaker than the pressing force (banknote holding force) of the rollers 30b and 30c, the vicinity of the insertion port 23 The bills 10 can be quickly aligned.

  FIG. 8 shows how the banknote width is detected when the banknotes 10 and 11 that are not bent are inserted into the insertion slot 23. In FIG. 8A, when the wide banknote 11 is inserted into the insertion slot 23, detection signals of the banknote 11 are output from all the inlet sensors 27 of the inlet sensors 27a, 27b, 27c, and 27d.

  On the other hand, when the narrow banknote 10 is inserted in the insertion slot 23, the detection signal of the banknote 10 is output from the two entrance sensors 27 located in the center of the entrance sensors 27b and 27c.

  FIG. 8B shows how the banknote width is detected when the narrow banknote 10 is inserted near one end of the insertion slot 23. In FIG. 8B, when the banknote 10 is inserted along the upper end (in the drawing) of the passage 24, the detection signal of the banknote 10 from the three inlet sensors 27b, 27c, and 27d. Is output. Conversely, when the banknote 10 is inserted along the lower end (in the drawing) of the passage 24, the detection signal of the banknote 10 is output from the three inlet sensors 27 of the inlet sensors 27a, 27b, and 27c.

  Thus, when the detection signal is output from all of the input sensors 27, it is determined that the wide banknote 11 has been input. When the output signal of the input sensor 27 is three or less, it determines with the narrow banknote 10 having been input.

  FIG. 9 shows a state of determination when the banknote 11 having a bent corner is inserted. FIG. 9A shows a case where a banknote 11 in which both ends 11c and 11d of the wide banknote 11 are bent is inserted.

  In this case, the detection signals of the two inlet sensors 27b and 27c are output first. However, thereafter, detection signals from the four inlet sensors 27a, 27b, 27c, and 27d are output in detection after a distance of about 10 mm has been reached. Therefore, it can be determined that the banknote 11 is wide.

  FIG.9 (b) is an example at the time of the banknote 11 bent only in one side being inserted. When only the end 11c of the banknote 11 is bent, the detection signals of the three entrance sensors 27a, 27b, and 27c are output first. However, thereafter, detection signals from the four inlet sensors 27a, 27b, 27c, and 27d are output in detection after a distance of about 10 mm has been reached. Therefore, it can be determined that the banknote 11 is wide.

  Similarly, when only the end 11d of the banknote 11 is bent, the detection signals of the three entrance sensors 27b, 27c, and 27d are output first. However, since the detection signals of the four inlet sensors 27a, 27b, 27c, and 27d are output after detection of a distance of about 10 mm, the wide banknote 11 can be determined.

  In this way, in the present embodiment, as shown in FIG. 7, the entrance sensor 27 detects the predetermined time indicated by the time points 75 and 76, so that even the banknote 11 that is bent is detected. Can do.

  FIG. 10 shows a state of determination when the folded banknote 10 is inserted. FIG. 10A shows the case of the banknote 10 in which both ends 10c and 10d of the narrow banknote 10 are folded.

  In this case, the leading edge of the banknote 10 may not be detected by the entrance sensor 27. However, the detection signals of the two inlet sensors 27b and 27c are output next. Thereafter, the detection signals of the two inlet sensors 27b and 27c are output in detection after traveling a distance of about 10 mm. Therefore, it can be determined that the banknote 10 is narrow.

  FIG. 10B shows an example in which a banknote 10 folded only on one side is inserted. When only the end 10c of the banknote 10 is bent, the detection signals of the two entrance sensors 27b and 27c are output first. Thereafter, detection signals of three inlet sensors 27b, 27c, and 27d are output in detection after about 10 mm. Therefore, it can be determined that the banknote 10 is narrow.

  Similarly, when only the end 10d of the banknote 10 is bent, the detection signals of the two entrance sensors 27b and 27c are output first. However, after that, in the detection after a distance of about 10 mm, the detection signals of the three inlet sensors 27a, 27b, and 27c are output. Therefore, it can be determined that the banknote 10 is narrow.

  As described above, in the present embodiment, detection is performed at two predetermined time points 75 and 76 as illustrated in FIG. 7, so that even the banknote 10 that is bent can be detected.

  Accordingly, it is possible to realize a banknote identification device that can correctly determine the insertion detection of the banknotes 10 and 11 and the detection of the banknote width without being affected by the bending of the corner portion.

  The banknote recognition apparatus of the present invention continuously draws even banknotes with different banknote widths without stopping for banknote width detection, so there is no sense of incongruity of insertion in banknote insertion, and banknotes that handle wide and narrow banknotes.
