[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. In the following, a description will be given with paper sheets represented by banknotes.
[0008]
FIG. 1 is a schematic diagram showing an example of a configuration of a bill automatic transaction apparatus 1 (hereinafter, ATM1) of the present invention. The ATM 1 is composed of several modules, and FIG. 1 shows a bill handling device 2 and an input / output device 3. The bill handling device 2 performs processing for handling bills, for example, processing for depositing and dispensing bills. A more detailed configuration and operation will be described later. The input / output device 3 is, for example, a combination of a monitor and a push button, or a touch panel in which both are combined. Through the input / output device 3, the operator of the ATM 1 selects and inputs processing such as deposit and withdrawal, or instructs the operator on the operation procedure. In addition, a module for handling cards, a module for handling passbooks, a module for handling coins, and the like may be provided.
[0009]
When depositing banknotes, the operator selects a depositing process from the input / output device 3. The shutter of the deposit and withdrawal port 4 is opened, and the bills are inserted in a bundle. The deposit / withdrawal port 4 draws out the banknotes one by one by a mechanism such as a payout roller around which rubber is provided, and sends out the banknotes to the transport path 5. The transport path 5 includes, for example, a belt and a roller, and transports the banknote by sandwiching the banknote and moving and rotating the belt and the roller. The discrimination unit 6 determines the authenticity of the conveyed bill from the optical or magnetic characteristics of the bill. Here, a banknote determined to be unsuitable for a transaction, such as a small banknote area due to a counterfeit note or torn, is switched to the gate 7 and returned to the deposit / withdrawal port 4. On the other hand, the banknotes determined to be transactable are stored in the temporary stacking unit 8. After the amount of money is confirmed between the operator and the input / output device 3, the banknotes are pulled out from the temporary stacking unit 8 and are conveyed to the stacking unit 9 via the conveyance path 5. When there are a plurality of stacking units 9, the gate 7 is switched to store, for example, banknotes for each denomination.
[0010]
On the other hand, when dispensing bills, the operator selects a dispensing process using the input / output device 3. The stacking unit 9 pulls out the designated number of bills and sends them out to the transport path 5. When it is determined that the banknote is inappropriate for dispensing when passing through the discrimination section 6, the gate 7 is switched and stored in the temporary accumulation section 8. Appropriate bills are stored in the cash slot 4. After storing a predetermined number of sheets, the shutter of the deposit / withdrawal port 4 is opened to bring the banknotes to the operator. The banknote B determined to be inappropriate is pulled out from the temporary stacking unit 8 and stored in the reject stacking unit 10.
[0011]
The ATM 1 performs the deposit and withdrawal processing by the above-described general operations. For this reason, the discriminating unit 6 needs to have a mechanism capable of discriminating in both directions, that is, the direction in which the sheet is conveyed from the deposit / withdrawal port 4 to the temporary stacking unit 8 and the direction in which the sheet is conveyed from the temporary stacking unit 8 to the stacking unit 9.
[0012]
Next, a side view of the identification unit 6 is shown in FIG. In the discriminating section 6, the bill is conveyed in both directions while being pressed and held between the conveyance guide 11a and the conveyance guide 11b by the driving roller 12 and the driven roller 13 which is in contact with the driving roller. In the middle of the transport, several kinds of bill information acquiring means 14 are provided, and the information acquiring means 14 acquires information for denomination and authenticity of the bill. The information acquisition unit 14 is, for example, a shape sensor that acquires the external shape of a bill using a CCD line sensor, a magnetic sensor that acquires magnetic information of a bill, a fluorescent sensor that acquires a fluorescent paint pattern of a bill, and the like. In the present embodiment, an information acquisition unit 14 using a magnetic sensor for acquiring magnetic information of a banknote will be described below as an example.
[0013]
FIG. 3 shows a conventional transport mechanism around the information acquisition means 14. The transport mechanism includes upper and lower transport guides 11a and 11b, a drive roller 12, a driven roller 13 in contact with the drive roller 12, and a roller 15 rotating in the transport direction. In this configuration, the height h2 of the conveyance path from the information acquisition unit 14 before and after the height of the conveyance path h1 from the information acquisition unit 14 immediately below the center of the roller 15 is larger. For this reason, if a certain section for acquiring bill information is set as the detection section A1, fluctuations up to h2 occur in the detection section A1, and bill information cannot be accurately acquired. In order to make h2 close to h1, the diameter of the roller 15 must be increased, which is difficult to mount.
[0014]
In this embodiment, in order to read magnetic information, as shown in FIG. 4, for example, a read point P and magnetization points Q1 and Q2 are provided. The transported banknote is magnetized at the magnetization point, and the magnetic information of the magnetized banknote is read at the reading point, thereby obtaining information on the banknote. The magnetizing points Q1 and Q2 are provided on both sides of the reading point P in order to cope with bidirectional conveyance, and the two magnetizing points Q1 and Q2 and the reading point P located between the magnetizing points are provided. At a total of three points, the distance between the bill and each point must be kept within a certain distance. In the mechanism shown in FIG. 4, when the bill 16 is conveyed, a variation of h2 occurs at the maximum between the bill and the magnetization point Q1, and it is impossible to uniformly magnetize the entire bill surface. At that time, even if the height at the reading point P is suppressed within h1, it is difficult to obtain accurate information of the bill 16.
[0015]
As a method that can solve this problem, for example, a mechanism using blade-like rollers as disclosed in JP-A-2-50289 and JP-A-2000-11268 can be considered. When the transport direction is reversed, the blades must be deformed in the opposite direction, and a large load is applied to the blade-shaped rollers, and durability is increased. There is a problem.
[0016]
In these information acquisition means 14, in order to obtain information accurately and with little variation in the detection section A1 on the information acquisition means 14 in the transport direction, the magnetization points Q1, Q2 and the reading point P and the transported bills are It is necessary to reduce the interval.
[0017]
In many cases, the bill information acquiring unit 14 has a configuration in which a plurality of information acquiring elements are arranged in a direction orthogonal to the transport direction in order to acquire information written on the entire bill surface. Several embodiments in which the above-mentioned problem is solved with respect to such a format of the bill information acquiring means 14 will be described below.
[0018]
FIGS. 5 and 6 show a banknote information acquisition unit 14 which is a first embodiment of the information acquisition device unit of the present invention.
FIG. 5 shows an example in which a movable roller whose position changes according to the transport direction is used to support bidirectional transport.
This mechanism moves the movable roller 18 to the upstream side in the bill conveying direction. Since the fluctuation of the bill passing through the roller 17 is suppressed by the roller 17 as compared with before the passage, the fluctuation of the height is suppressed on the information acquisition unit 14 even with a folded bill or the like.
[0019]
In the mechanism shown in FIG. 5, bills are rotated by rotating upper and lower transport guides 11a and 11b, two pairs of drive rollers 12, a driven roller 13 pressed and held between driven rollers 12, and a roller 17 on an upper part of the information acquisition means 14. Is being transported. Here, the movable roller 18 has a roller shaft 19 on the upper part of the information acquisition means 14, a rotatable fulcrum 21 of a link 20, and a point where a shaft 23 of a solenoid 22 is mounted on the opposite side of the roller shaft 19 with respect to the fulcrum 21. 24, three points on the link, the link 20, and the roller 17. By moving the solenoid 22 in the direction A of FIG. 5, the movable roller 18 is moved and the position of the roller 17 can be shifted. The driving force of the roller 17 is transmitted from a motor (not shown) via a gear 25, a gear 27, and a drive belt 26.
[0020]
Here, the movable roller 18 refers to a roller as a guide unit constituting the information acquisition unit 14 and a roller moving mechanism described above. The roller 17 is an example of the movable roller 18 in a case where bills are conveyed in the direction of arrow B as shown in FIG. 5, for example.
[0021]
When the banknote is transported in the direction B shown in FIG. 5 (left direction in this case), the solenoid 22 is moved in the transport direction B (left direction in this case). As a result, the movable roller 38 is inclined in a direction opposite to the transport direction B (in this case, on the right side). Thereby, the rotating roller 17 can be shifted in the direction opposite to the transport direction (in this case, rightward), and the height of the bill from the unit 14 can be suppressed by the first half on the information acquiring unit 14.
[0022]
When the transport direction is reversed (rightward), the solenoid 22 is moved in the banknote transport direction (rightward), and the gear 25 is turned clockwise to incline the movable roller 18 to the left, thereby causing the roller 17 to rotate. Rotate counterclockwise. As described above, by moving the solenoid 22 and changing the rotation direction of the gear 25, the height of the bill on the information acquisition unit 14 can be suppressed, and a mechanism for obtaining more accurate information can be obtained.
[0023]
As described above, by moving the roller 17 to the upstream side in the transport direction of the banknote, there is also an effect that the height of the banknote on the information acquisition unit 14 can be suppressed even when the banknote is transported in both directions.
[0024]
FIG. 6 shows a mechanism similar to the mechanism shown in FIG. 5, but in which the solenoid 22 can be omitted. In this mechanism, the movable roller 18 includes a roller shaft 19 on the upper part of the information acquisition unit 14, a fulcrum 21 of the link 20, the link 20, and the roller 17. Here, the position of the movable roller 18 is changed by the gear 25. For this purpose, a friction generating means such as a torque limiter is inserted between the gear 27 and the fulcrum 21, and a part of the driving force from the gear 25 is used as the rotational force of the link 20. In the mechanism of FIG. 6, when the bill is conveyed in the direction B shown in FIG. 6, by rotating the gear 25 counterclockwise for conveyance, the drive belt 26 rotates in the direction of arrow C, and the roller 17 It is rotating clockwise. The drive belt 26 also rotates in the direction of arrow C, and the fulcrum 21 of the link 20 also rotates clockwise. Here, since the link 20 and the fulcrum 21 of the link are fixed, when the fulcrum 21 of the link rotates clockwise, the link 20 itself also tilts rightward. Similarly, when the transport direction is reversed, the rotation direction of the gear 25 is clockwise, so that the drive belt 26 rotates counterclockwise, and the fulcrum 21 of the link rotates counterclockwise. Thereby, the link 20 tilts to the left.
[0025]
Thereby, similarly to the mechanism of FIG. 5, the height of the banknote can be suppressed in the detection section on the banknote information acquisition unit 14, and it is possible to cope with a change in the transport direction.
[0026]
Further, the circumferential position of the movable roller 18 at which the position with the bill information acquiring unit 14 is minimum (hereinafter, the minimum circumferential position) is between the magnetization point Q1 (or Q2) and the reading point P. Driven to move the position. The optimal position of the movable roller 18 is appropriate when the minimum circumferential position is near the intermediate point between the magnetization point Q1 (or Q2) and the reading point P. In the case of a banknote that is easily magnetized, it is possible to read accurate information at the reading point P by shifting the minimum circumferential position in the direction of the reading point P. The optimal position of is corrected.
[0027]
A second embodiment is shown in FIGS.
FIG. 7 is a perspective view of the bill information acquiring means 14, wherein a step is formed on a surface close to the bill, and a convex surface is defined as a surface 31 and a concave surface is defined as a surface 32. In this figure, the pitch of the surface 32 is d. The surface 31 and the surface 32 do not have to be flat, and any mechanism may be used as long as a step can be formed. At this time, the information acquisition element is arranged on the convex surface 31 to acquire information on the bill. As shown in FIG. 8, the roller 15 attached to the shaft 33 at a pitch d is disposed above the banknote information acquisition unit 14 so as to face the concave surface 32 in the horizontal direction. In the vertical direction, a space is provided between the roller 15 and the concave surface 32.
[0028]
FIG. 9 shows a side view of the entire mechanism including the paper sheet information acquisition means 14. The bill is pressed and held between the upper and lower transport guides 11a and 11b by two pairs of drive rollers 12 and driven rollers 13. The sheet is conveyed by rotating a roller 15 above the information acquisition unit 14. FIG. 10 shows a section taken along section F in FIG. 8 to describe the details of this mechanism. In FIG. 10, a roller 15 is provided so as to enter the information acquisition unit 14 from the convex surface 31. Here, the distance between the outer periphery of the roller 15 and the convex surface 31 is defined as an overlap amount OV.
[0029]
When the bill is conveyed on the information acquiring means 14, the bill 16 is deformed into a waveform as shown in FIG. 10, and the bill 16 is conveyed while being pressed against the information acquiring surface 14 on the information acquiring means 14. . Therefore, in FIG. 9, in the section A2 where the information acquisition unit 14 and the roller 15 overlap, the height of the banknote 16 can be suppressed on the information acquisition unit 14, so that the information acquisition of the banknote 16 can be performed accurately. Can be. This section A2 corresponds to a detection section, and has a magnetization point and a reading point in the section A2.
[0030]
FIG. 12 shows a mechanism in which a low-rigidity brush 35 is attached to the outer periphery of the roller 15. The structure of the bill information acquiring means 14 has irregularities on the bill contact surface as in FIG. 7, and the information acquiring element is arranged on the convex surface 31 to acquire information on the bill 16. Further, as shown in FIG. 11, the transport method is the same as the above-described transport method except that a brush 35 is provided on the outer periphery of the roller 15. However, in the upper part of the banknote information acquiring means 14, the roller 15 attached to the shaft 33 at a pitch d is arranged such that the outer periphery of the brush 35 has a convex surface 31 in the vertical direction so as to coincide with the position of the concave surface 32 in the horizontal direction. The brush 35 is configured to be pressed so as not to cause a problem in the durability of the brush 35 from the point where it enters the information acquisition unit 14.
[0031]
The operation is the same as the operation of the above-described mechanism, and the height of the banknote 16 can be suppressed on the information obtaining unit 14, so that the information of the banknote 16 can be obtained accurately. Further, since the brush 35 has a lower rigidity in the diameter direction than the roller 15, as shown in FIG. 12, it is possible to softly hold the banknote and reduce breakage. Further, since there is an overlap, the pressing amount may be small, and there is no problem in the durability of the brush 35.
[0032]
The overlap amount OV is determined firstly by the bending stiffness of the banknote handled by the information acquisition means 14, and secondly by the distance between the convex surface 31 and the roller 15 at the magnetization point in the relationship with the magnetization point Q1 or Q2. . The first point is considered from the viewpoint of preventing jamming of bills, and the second point is considered from the viewpoint of ensuring the accuracy of information to be acquired. Note that in the relationship with the reading point P1, if the overlap amount OV ≧ 0, the banknote information can be read at the reading point.
[0033]
In the two mechanisms described with reference to FIGS. 9 and 11, a step is formed between the surfaces 31 and 32 which are the acquisition units of the bill information acquisition unit in FIG. 7, and the rollers 15 or the brush 16 press the bills above the surface 32. Thus, the mechanism is such that the height of the bill from the information acquisition means on the surface 31 which is the information acquisition surface is suppressed.
[0034]
Further, in the cross-sectional view of the mechanism shown in FIG. 13, the brush 35 is attached to the shaft 33 and the brush 35 is attached to the entire outer periphery of the second roller 36 having a smaller diameter than the roller 15 with respect to the position of the surface 31 on which the information acquisition element is arranged. . The second roller 36 is effective in suppressing the distance of the bill conveyed onto the information acquiring unit 14 from the surface 31.
Further, the brush 35 is configured at a position where the second roller 36 attached to the shaft 33 at a pitch d is spaced from the position of the convex surface 31 in the horizontal direction, and durability is a problem in the vertical direction. By configuring the paper money in such a range that the paper money is pressed to a certain extent, the effect of suppressing the distance of the bill conveyed onto the information acquisition unit 14 from the surface 31 can be further increased. The transfer method is the same as the transfer method using the mechanism shown in FIGS. 9 and 11 described above.
[0035]
The operation is the same as the operation of the mechanism described above.
Thereby, the same effect as the effect obtained by the mechanism of FIGS. 9 and 11 can be obtained. Furthermore, even the banknotes that have been deformed, for example, bent on the surface 31 in the transport direction, are pressed by the brush 35 on the surface 31 so that the height of the banknote 16 on the surface 31 at the information obtaining position from the information acquisition unit is reduced. This also has the effect of improving information acquisition accuracy.
Further, as another mechanism, a roller may be used instead of the brush 35 on the surface 31 to keep the distance between the surface 31 and the roller so that the bill 16 is not jammed.
[0036]
A third embodiment is shown in FIGS.
FIG. 14 is a diagram showing a mechanism in which an information proximity surface which is a detection section of the bill information obtaining means 14 is an arc surface 38 and information acquisition elements, that is, magnetization points and read points are arranged on the arc surface 38.
[0037]
As shown in FIG. 15, a shaft 33 is installed above the bill information acquiring unit 14 such that the roller 15 is concentric with the arc surface 38 of the information acquiring unit 14. Note that the diameter of the roller 15 is smaller than the diameter of the circle including the arc surface 38 of the information acquisition unit, and the distance between the roller 15 and the arc surface 38 is set to be larger than the thickness of the banknote so that the conveyed banknote is not jammed. Deploy. FIG. 16 shows a side view of the entire mechanism including the information acquisition means 14. The bill 16 is formed by two pairs of drive rollers 12 and driven rollers 13 with the upper and lower transport guides 11 a and 11 b and the information acquisition means 14 interposed therebetween. It is pressed and held, and is further conveyed by rotating a roller 15 above the information acquisition means 14.
[0038]
In the mechanism of FIG. 16, when the transported banknote 16 is transported onto the information acquisition unit 14, the banknote 16 is transported in the gap between the arc surface 38 of the information acquisition unit 14 and the rotating roller 15.
In this mechanism, by forming the arc surface 38 on the information acquisition surface, the height at which the bill is conveyed from the information acquisition surface is limited to a certain height or less over a wider range than the information acquisition means 14 having a flat information acquisition surface. it can.
[0039]
In this arc surface 38, it is desirable that the magnetized points Q1 and Q2 are arranged at an end of the arc surface 38, that is, at a corner R formed by forming the arc surface 38 (see FIG. 14). . The corner R is a boundary between the arc surface 38 and the horizontal plane, and the transported bill is guided by the roller 15 so as to be in contact with the corner R when moving on the information acquisition unit 14. Therefore, by arranging the magnetization points at the corners R, stable magnetization is possible.
[0040]
As in the second embodiment, a low-rigidity brush 35 may be attached to the entire surface of the roller 36 around the shaft 33 as shown in FIG. 17 so that the brush 35 comes into contact with the bill information acquiring means 14. Also in this mechanism, the distance of the bill from the bill information acquiring means 14 can be reduced by making the brush contact the arc and having no problem in durability, and the same effect as described above can be obtained.
[0041]
Further, as shown in FIG. 18, the positional relationship between the arc surface 38 and the roller 15, which has been described as concentric circles in the above description, is changed. By making the diameter of the arc surface 38 of the information acquisition means 14 larger than that of the concentric circle, the center 39 of the arc is set above the center of the roller 15 while maintaining the shortest distance between the roller 15 and the information acquisition device 14. it can. As a result, at the entrance of the arc, the distance between the arc surface 38 and the roller 15 is larger than the distance between the arc surface 38 and the roller 15 in the case of a concentric circle, so that the bill can easily enter smoothly. The banknotes can be transported on the acquisition device 14 without being clogged.
[0042]
In the third embodiment, the range of movement of the banknote can be maintained by the roller 15 on the arcuate surface 38. Further, by overlapping the outer peripheral portion of the roller 15 so that it is located on the information acquisition device position side from the line connecting both ends of the arc surface 38 of the information acquisition device 14, as shown in FIG. The distance between the acquisition device 14 and the bill can be reduced so that the bill is almost conveyed.
[0043]
According to the three embodiments described above, it is possible to maintain the height of the bill over a predetermined section. Therefore, even when using two types of points, such as a magnetic sensor, a point for magnetizing the magnetism of a bill, a reading point, and a reading point, both points can maintain the height of the bill, and information can be stored. Can read stably.
[0044]
Further, when a CCD sensor that captures an image of a banknote is used as the information acquisition device, the depth of the subject can be set to a certain value or less. In the above description, bidirectional is a prerequisite. However, even in the case of acquiring information in one direction, the above three embodiments can of course be used.
[0045]
Furthermore, although the embodiments have been described using banknotes as paper sheets, these embodiments can be applied to other paper sheets. Here, the information acquisition means of the automatic bill transaction apparatus has been described, but the invention is also applicable to, for example, an optical system for image capture in a paper sheet handling apparatus such as a copy and a scanner. As a result, the distance between the paper sheet and the optical sensor can be reduced, and a stable image can be captured.
[0046]
【The invention's effect】
According to the present invention, recognition accuracy can be improved by keeping the distance of a bill conveyed at high speed in both directions within a certain section from the information acquisition means within a predetermined distance, and a durable paper leaf A class information acquisition device can be provided.
