Description

Banknote handling device

The present invention relates to a banknote handling apparatus.

BACKGROUND ART Conventionally, in an automated teller machine called an ATM (Automated Teller Machine), banknotes bundled into an input port are separated one by one by a mechanism for delivering banknotes to the input port, and stored in an ATM.

Normally, the supplied bank-note bundles are separated one by one and conveyed. In the case where foreign matter other than banknotes is mixed or foreign matter is attached to the banknote, the foreign object may be mixed into the conveying path at the time of separating the banknote. In this case, there may be a case in which a bill with a foreign object attached or a bill after the foreign object is attached is clogged during transportation.

In order to avoid such a trouble, for example, Patent Document 1 discloses a technique of stopping the foreign object detecting sensor on the conveying path side when it is judged that a foreign object is attached to the foreign object detecting sensor on the banknote bundle.

Japanese Patent Application Laid-Open No. 2008-210303

As foreign matters, there are paper media other than paper money such as coins, paper other than paper money such as receipts. However, in many countries, banknotes are often put into a deposit / withdrawal port while being bundled with rubber strings, staples, money clips, or the like. Therefore, in addition to the medium or the paper medium, a holding medium for bundling such paper money can also be a foreign matter.

As a method of detecting these foreign objects, there is a method of photographing the entire banknote with a camera. However, since the shape of a banknote varies, it can not be determined whether it is a foreign object or a shape. Even if it is judged that the shape of the bill is not the shape of the bill, it may be a graffiti on the bill. Therefore, it is not easy to detect the foreign object from the image captured by the camera. For this reason, there has been a demand for a technique capable of accurately acquiring an image.

When the foreign object is detected by the sensor on the conveying path as in the technique disclosed in Patent Document 1, the bills and foreign objects are already in the conveying path at the time when it is detected that there is a foreign object. For this reason, even if the banknote transaction apparatus attempts to half-angle the banknote to the customer, the banknote can not be half-angle to the customer, and it may become necessary to take counterparts such as removal of the foreign object by the person in charge (taking out the banknote). Therefore, there has been a demand for a technique capable of detecting a foreign object before entering the conveying path and making it possible for the customer to half-fold the bill.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a bill handling apparatus capable of precisely acquiring an image at the time of forwarding a bill from a bill deposit / withdrawal port. Secondly, another object is to provide a bill handling apparatus capable of detecting a foreign object before entering the conveying path.

In order to solve the above-mentioned problems, in order to achieve the object, a banknote handling apparatus according to the present invention comprises a bill accommodating space for accommodating a bill inserted from a bill insertion slot, the bill accommodating space including a push plate, A conveying roller for conveying the banknotes on the conveying path provided in the forward direction to advance the banknotes from the banknote storage space or the gate rollers disposed at the opposed positions of the conveying rollers and the banknote stored in the banknote storage space Wherein a banknote clamping portion is formed by an end of the pressure plate on the paper catching side and an end of the front plate on the paper catching side in a space formed between the advance rollers leading to the conveying path, , The banknotes of the banknotes held by the advance roller and the pressure plate, the banknote holding portion, the conveying roller, or the gate roller And an image pickup section for picking up an image of the holding section.

According to the present invention, it is possible to precisely acquire an image at the time of withdrawing banknotes from a banknote deposit / withdrawal port. Further, the foreign object can be detected before entering the conveying path.

5 is a configuration diagram of the banknote deposit / withdrawal port 103 or its periphery. In the upper portion of the banknote deposit deposit / withdrawal port 103, there is provided a deposit / withdrawal port cover 202 for restricting access to the banknote deposit / withdrawal port 103. The bank note deposit and withdrawal port 103 has a front plate 205, a pressure plate 204, and side walls (not shown) that form a banknote storage space of the banknote deposit and withdrawal port 103. The pressure plate 204 forms a surface facing the front plate 205 and is moved toward the front plate 205 by a driving source (not shown) when the banknotes are discharged. The front plate 205 is configured so as to face the accumulating surface of the paper currency stacked in the pressure plate 204 or the pressure plate 204 in the direction of the paper currency deposit / (204) or in a direction away from the accumulation surface. A gap is provided on the surface of the front plate 205, and the advance roller 208 contacts the paper currency from the gap (see FIG. 6). A conveying roller 209 for conveying the banknotes that have been passed from the deposit / withdrawal port 103 by the outflow roller 208 to the conveying destination, and a conveying roller 209 A gate roller 210 is further disposed at a position opposite to the gate roller 210. [ The gate roller 210 rotates in a direction opposite to the conveying direction, thereby suppressing the double feeding of banknotes.

A camera 207 for photographing the inside of the banknote deposit / withdrawal opening 103 or the inserted banknote (including the shadow of the unevenness of the surface of the banknote) is provided at or around the banknote deposit / The pressure plate 204 and the front plate 205 constitute a paper currency holding portion A in which paper currency is sandwiched and held between the lower ends of the paper currency holding portion A and the front plate 205. The camera 207 functions as a paper currency holding portion A, (In the vertical direction in Fig. 5 or on the conveying surface of the banknote, also referred to as the banknote conveying direction) of the banknote holding portion A or the banknote holding portion A have. The banknote holding portion A may be provided between the conveying roller 209 or the gate roller 210 and the vertically extending direction of the leading roller 208. [ That is, the banknote gripping portion A is disposed in the space formed between the conveying roller 209 or the gate roller 210 and the leading roller 208, Of the banknote counterpart side. The vertical direction may also be referred to as a forward direction in which the banknotes are successively advanced.

The camera 207 can also be arranged between the vertical direction of the banknote paper nip portion A and the advance roller 208 even when the position of the lens portion B serving as the image pickup portion is disposed at a position different from the above- It is possible to pick up the paper money to be conveyed / ejected at a position held by the paper currency holding portion A. 5, the lens portion B serving as an image pickup portion of the camera 207 is directly moved between the advance roller 208 and the conveying roller 209 so as to directly contact the banknote gripping portion A However, one or a plurality of mirrors may be provided between the advance roller 208 and the conveying roller 209 to pick up the paper currency holding portion A through the mirror (the camera 207 'in Fig. 5) ). The image of the banknote gripping portion A can be picked up even if there is a physical restriction that the lens can not be directly directed to the banknote gripping portion A by imaging the banknote gripping portion A via the mirror .

5, the camera 207 is provided on the side of the front plate 205, but the camera 207 may be provided on the side of the pressure plate 204 (camera 207 "of FIG. 5) or both. Although a single camera 207 is provided in Fig. 5, a plurality of cameras 207 may be provided to increase the accuracy of the camera 207. When the camera 207 is provided on the side of the pressure plate 204, The banknote gripping portion A is imaged by pointing the lens portion B which is an image pickup portion of the camera 207 between the outward side end portion of the pressure plate 204 and the gate roller 210, The camera 207 may be disposed over the pressure plate 204 and the front plate 205. When the lens serving as the image sensing unit is disposed above the banknote It may be directed to the branch portion A.

In the present embodiment, the image sensing unit is provided at a position sandwiched between the banknote catching unit A and the advance roller 208 or the banknote catching unit A, or the image of the position is captured, It is possible to suppress the shift of the image due to the vibration or the like generated at the time of the succession. In the case of between the banknote gripping portion A and the forwarding roller 208, a part of the banknote gripping portion A, a rotary shaft of the forwarding roller 208, or the banknote gripping portion A are held in contact with the banknote Between the nipping position and the succeeding position where the leading roller 208 comes into contact with the banknote. The camera 207 has a structure in which the lens portion B serving as an image pickup portion is positioned between the vertical direction of the conveying roller 209 or the gate roller 210 and the leading roller 208 as described above . Therefore, the image pickup section is provided between the conveying roller 209 or the gate roller 210 and the leading roller 208, or the image of the position is picked up, and in the vertical direction, the banknote is held in the state shown below It is possible to suppress the shift of the image due to the vibration or the like at the time of conveyance from the succeeding time. The rotating shaft of the conveying roller 209 or the rotating shaft of the gate roller 210 and the rotating shaft of the leading roller 208 or between the rotating shaft of the conveying roller 209 and the gate roller 210, Is a concept that includes a position where the conveying roller 209 comes in contact with the banknote or a position where the gate roller 210 comes in contact with the banknote and a position where the succeeding roller 208 comes in contact with the banknote.

The distance in the vertical direction between the conveying roller 209 or the gate roller 210 and the leading roller 208 may be shorter than the length in the conveying direction of the banknote to be conveyed. This makes it possible to sandwich the bill that is advanced in the conveying direction at three points of the take-out roller 208 and the pressure plate 204, the banknote holding portion A, the conveying roller 209, or the gate roller 210 . Therefore, as compared with the case where the distance in the vertical direction is longer than the length in the conveying direction of the banknote to be conveyed from the time of the succession of the banknotes to the completion of succession of the successive rollers 208, It is possible to suppress misalignment of the picked-up image by the camera 207,

6A, the two advance rollers 208 are arranged in the widthwise direction of the banknote 401 in the transverse direction of the banknote 401, as shown in Fig. 6A, (In a direction perpendicular to the conveying direction of the banknote on the conveying surface of the banknote), as shown in Fig. This makes it easy to detect the operation of the banknote when foreign objects are present, so that foreign objects can be easily determined. A concrete foreign matter determination method will be described later.

6 (a), the camera 207 may be disposed at the position where it is fitted in the lateral direction of the banknote to the advance roller 208 and the conveying roller 209. Further, as shown in Fig. Thus, by disposing the lens portion B, which is an image pickup portion, between the conveying roller 209 and the advance roller 208 and picking up the position, the banknotes are held in the lateral direction of the banknote, It is possible to suppress image shift due to vibration in the width direction or the like.

As described above, the front plate 205 may have a space for the camera 207 to pick up the banknote. In addition, the banknote deposit-and-withdrawal port 103 or the periphery thereof is provided with an illumination 206 constituted by an illumination device such as an LED. The illumination 206 may be in a position to irradiate light at an acute angle to the conveyed or outgoing bill between the conveying roller 209 or the gate roller 210 and the advance roller 208. [ For example, as shown in Fig. 5, the illumination 206 may be arranged such that the angle a formed by the conveying surface C of the banknote and the optical axis D of the illumination 206 becomes an acute angle. In the case where the bill deposit / withdrawal outlet lid 202 is transparent, or when foreign objects can be determined as described below by using external light, the bill 206 may be omitted. In the following, the still image is primarily described with respect to the foreign object determination method, but the image to be captured may be a moving image. In this case, the still picture may be extracted from the moving picture at predetermined intervals.

Next, the operation of the deposit-and-withdrawal port 113 will be described. The deposit and withdrawal port cover 202 slides to the closed position 203 and the pressure plate 204 contacts the front plate 205 under the control of the control unit 112 after the banknote 201 is inserted in the deposit- The banknote 201 is inserted. The foreign object determination mechanism section 120 turns on the illumination light 206 in accordance with an instruction from the control section 112 and the camera 207 starts imaging the banknote gripping section A. [ Thereafter, the advance roller 208 and the conveying roller 209 are driven to rotate by a driving source (not shown), and the banknote 201 is delivered to the conveying path 211. The pressure plate 204 and the front plate 205 may be provided with protrusions at contact portions of the banknotes 201 to enhance the suppression. By providing such a protruding portion E (see Figs. 5 and 6), it is possible to further reliably suppress misalignment of the image and shift of the focus. 5 and 6, the projecting portion E shows the case where the delivery roller 208 and the banknote are in the same position (in Fig. 5, the extension roller 208 and the projection overlap each other) The position may be shifted in the conveying direction of the banknote.

7 is a view showing the periphery of the banknote gripping portion A by the camera 207 when the advance roller 208 is rotated. The image photographed by the camera 207 includes a shadow formed by the unevenness of the surface of the banknote by aligning the illumination 206 with the banknote at an acute angle in addition to the shape printed on the surface of the banknote. Therefore, even if there is no shape, there is a certain pattern. In addition to the visible light, the wavelength of the illumination 206 may be light of other wavelengths such as infrared light or ultraviolet light, if the pattern on the banknote can be picked up.

In the present embodiment, the camera 207 continuously picks up paper money in the succeeding banknote. Therefore, when the image 301 captured at the timing before the preceding one is compared with the image 302 captured at the next timing, the pattern of the position 303 at the center of the image 301 picked up in front of the image 301 becomes the next To the position 304 in the image 302 picked up by the image pick-up device. This is because the banknote moved from the central position 303 to the position 304 during image capture, and the movement amount of the pattern coincides with the movement amount of the banknote. The pattern is a characteristic of a change in lightness or color. For example, there is a shadow of the surface of the paper currency printed on the surface of the paper currency, the unevenness of the surface of the paper currency caused by the contamination of the paper currency,

The movement of the pattern can be detected on all or a part of the image captured by the camera 207 during rotation of the advance roller 208 and the moving amount of the paper money can be obtained by accumulating the amount of movement. For detecting the movement of the pattern, for example, a known method such as optical flow can be applied. This method includes known methods such as a block matching method and a gradient method.

6 (a) is a perspective view of a banknote deposit / withdrawal port 103 at the time of conveying foreign matter-bills. In the case of foreign matter-free banknotes, the paper currency holding portion A, in which the pressure plate 204 and the front plate 205 sandwich the paper currency 201, is rotated by the forward roller 208 The banknote holding portions A of the two positions are positioned at the positions of the banknote holding portions A in the width direction of the banknote 401, And moves in the same direction as the banknote conveying direction.

6 (b) is a perspective view of the paper currency deposit and withdrawal port 103 at the time of conveyance of paper currency in the presence of foreign matter. When the clip 402 is attached to the banknote 201, the copper line X 'of the banknote 403 being conveyed, which is detected by the camera 207 disposed on the left and right outside the widthwise direction of the advance roller 208, , A difference occurs in the length of the left and right copper lines. Therefore, by comparing the detected copper wire X ', the rotation of the banknote can be detected, and foreign matter can be detected without directly recognizing the foreign matter from the image. That is, the presence or absence of foreign matter can be determined by detecting the operation of the banknote. A specific example thereof will be described with reference to Fig.

8, the details of the foreign object detection at the time of insertion of the bill will be described. Fig. 8 is a flowchart showing a processing procedure of a foreign object detection process at the time of inputting a bill. When the deposit / withdrawal port 103 receives the banknote inputted from the user (S801), the control section 112 closes the deposit / withdrawal port cover 202 (S802) and lights the light 206 (S803).

After the camera 207 picks up an image of the banknote gripping portion A at the initial timing (S804), the advance roller 208, the conveying roller 209, and the gate roller 210 are rotated, And the banknotes are introduced into the apparatus one by one (S805). The banknote motion detection program 124 of the image processing unit 123 captures the image of the banknote catching unit A captured at this timing by the camera 207 at the following timing (S806) The image is compared with the image picked up at the preceding timing, and the movement of the bill is calculated as shown in Fig. 7 (S807). The banknote motion detection program 124 determines whether or not the motion stop time is equal to or less than the threshold value (S808). If it is determined that the motion stop time is equal to or smaller than the threshold value (Y in S808) And accumulates the bill (S809). The movement trajectory of the paper currency can be grasped by calculating the cumulative value of the movement of the paper currency as described above.

Further, the bank note motion detection program 124 calculates the rotation angle of the banknote from the cumulative value calculated for each of the right and left sides, and determines whether or not the calculated rotation angle is equal to or larger than the threshold value (S810). When the bank note motion detection program 124 determines that the skew has been detected and determines that the skew has been detected, the control unit 112 determines that skew has been detected and determines that the skew is detected by the advance roller 208, the conveying roller 209, The rotation of the roller 210 is stopped to stop the succession of banknotes (S811).

The rotation angle ?? can be obtained by the following equation using the accumulated value l _L of left motion, the accumulated value l _R of right motion, and the distance D _LR between the left and right cameras.

[Formula 1]

The foreign substance judging program 125 judges whether or not the cumulative value of the left and right stars calculated in S809 is larger than the threshold value. If judged that the cumulative value is larger than the threshold value (S812: N) And terminates the processing abnormally. On the other hand, when judging that the accumulated value is equal to or smaller than the threshold value (Y in S812), the foreign substance judging program 125 judges that the degree of entry of the foreign object into the conveying path is small, The conveying roller 209 and the gate roller 210 are rotated in the direction opposite to the conveying direction so as to half-turn the banknotes in the outgoing slot 103 (S814) The cover of the deposit-and-withdrawal port 103 is opened (S815), the bill is reintroduced to the user, and the process is repeated.

When the banknote movement detection program 124 judges that the rotation angle is less than the threshold value (N in S810), the bill detection unit 124 continues the foreign object detection until the banknote disappears in the deposit-and-withdrawal opening 103 (Y in S817).

Further, when it is judged that the movement stop time is larger than the threshold value (S808: N), the bill movement detection program 124 judges that all the bills have been transported, and after the accumulation value is initialized, 125 continues the foreign object detection until the banknote is removed from the deposit-and-withdrawal port 103 (S817: Y). That is, when the stopping time of the motion is larger than the threshold value, it can be considered that the next accumulated banknote is picked up with one bills conveyed. Therefore, in such a case, the banknote motion detection program 124 initializes the cumulative value to calculate the motion of the next banknote, and continues the foreign object detection until the accumulated banknote disappears.

The determination as to whether or not there is a banknote in the deposit-and-withdrawal port 103 is made so that a fixed pattern is printed on the camera 207 when no banknote is present and when the pattern is picked up, It may be determined that the pattern imparted to the banknote is exposed and no banknote is present, or another sensor may be used.

If the foreign object determining program 125 determines in step S517 that the banknote to be transported is gone (S817: N), the control unit 112 determines whether the banknote to be transported is missing (S818), and the banknote charging process ends normally (S819).

By detecting the movement of one sheet of paper money by the above constitution and operation, it is possible to quickly detect the foreign object in the middle of the paper currency in the succeeding step of the paper currency, and stop the foreign object before entering the conveyance path. Therefore, it is possible to prevent the foreign object from being mixed into the conveying path by mistake, thereby preventing clogging of the foreign object. Further, even when the foreign object enters the conveying path, it is possible to detect the foreign object at an early stage of the conveying path, so that it is possible to shorten the time until recovery.

The detection of the foreign object is not limited to the case where the foreign object is bundled by the foreign object and the foreign object is located just in front of the banknote and the foreign object can not be distinguished from the banknote or the foreign object exists between the banknote and the banknote, The foreign object can be detected if the foreign object is caught by either one of the left and right outward rollers 208 and the banknote is conveyed by the one of the forward rollers 208.

Fig. 9 is a configuration diagram of the banknote deposit and withdrawal port 103 or its vicinity in the second embodiment. 9, in Embodiment 2, a member such as a plate 602 is provided so that the camera 207 can be fixed to the front plate 205, the light 206 is fixed to the front plate 205, And the spring 601 presses the banknotes while the banknotes are continuously being discharged by a control device such as a solenoid. Since the front plate 205 follows the surface of the banknote, the distance between the camera 207 and the illumination 206 can be kept constant with respect to the surface of the banknote, so that the deviation of the focus can be suppressed, It is effective.
