  By the way, as an automatic teller machine, there exists a thing which has the switch which switches the conveyance path | route of a banknote in a conveyance part. This switch is comprised by the blade which contact | abuts a banknote, for example, and determines the advancing direction of the said banknote, and the actuator which rotates the said blade and switches the advancing direction of a banknote. Among these, the actuator has a built-in solenoid coil, for example, generates a magnetic force based on the supplied electric power, and rotates the blade using this magnetic force.

  Here, when the magnetic field generated by the solenoid coil of the actuator reaches the magnetic sensor, it becomes magnetic noise, which may reduce the accuracy of detecting magnetism from the banknote. For this reason, in the automatic teller machine, for example, the influence of the actuator on the magnetic sensor is reduced as much as possible by covering the discrimination part with a housing made of a magnetic material and disposing the actuator at a location away from the discrimination part. .

  As a result, the magnetism generated by the actuator can be shielded by the magnetic shield separated from the surrounding members on the magnetic circuit, so that the magnetic sensor and the actuator are close to each other according to the arrangement of each roller. The influence on the magnetic sensor from the actuator can be minimized.

[3. Configuration of the identification section]
[3-1. Conveying path and differential conveying roller group configuration]
As shown in the enlarged left side view of FIG. 4, the discrimination section 14 is provided with a conveyance guide 30 so as to tie approximately the center in the vertical direction along the front-rear direction. The conveyance guide 30 includes an upper conveyance guide 30A on the upper side and a lower conveyance guide 30B on the lower side.

  The upper conveyance guide 30A and the lower conveyance guide 30B are both made of a resin material, and a gap of about 5 mm is formed between the lower surface of the upper conveyance guide 30A and the upper surface of the lower conveyance guide 30B, and this gap is conveyed. The route is W1.

  In addition, short conveyance paths W2 and W3 respectively extending in the vertical direction from the branch point P1, which is the front end of the conveyance path W1, are formed by the conveyance guide 30 at the front end portion in the discrimination unit 14. The transport path W2 is connected to the upper deposit / withdrawal unit 12 (FIG. 2) at the upper end. Further, the transport path W3 is connected to the reject container 16 (FIG. 2) at the lower end.

  A transport roller 31 is disposed near the upper end of the transport path W2. The transport roller 31 is a group of rollers each having a short cylindrical or disc-shaped roller with a central axis directed in the left-right direction and arranged in a discrete manner in the left-right direction, one group before and after the transport path W2. It arrange | positions so that a side surface may contact | abut on the said conveyance path | route W2, ie, the conveyance path | route W2 is pinched | interposed from the front-back direction. Incidentally, one of the roller groups is driven to rotate clockwise or in the opposite direction in the figure by supplying a driving force from a power source (not shown), and the other is driven to rotate.

  A transport roller 32 is disposed near the lower end of the transport path W3. The transport roller 32 is configured in the same manner as the transport roller 31, and each roller group is arranged so as to sandwich the transport path W3 from the front-rear direction.

  The conveyance guide 30 is provided with detection units, conveyance rollers, a switching unit, and the like so as to be sequentially arranged along the conveyance path W1. Specifically, a reject switching unit 23 is disposed in the vicinity of the front end (that is, the branch point P1) of the transport path W1. Behind the reject switching unit 23, in order from the front side along the conveyance path W1, the conveyance roller 33, the magnetic detection unit 34, the conveyance roller 35, the light emission detection unit 36, the conveyance roller 37, the thickness detection unit 38, and the conveyance A roller 39 is arranged. Further, the reject switching unit 23 is provided with a blade 42 that switches the banknote traveling direction at a position between the transport roller 31 and the transport roller 33 (details will be described later).

  The transport rollers 33, 35, 37, and 39 are configured similarly to the transport rollers 31 and 32, respectively. Further, between the transport rollers 33 and 35, between the transport rollers 35 and 37, between the transport rollers 37 and 39, between the transport rollers 33 and 31, and between the transport rollers 33 and 31, the transport path W1, W2 or W3 The distance along the length is shorter than the length along the traveling direction of the banknote, that is, the length of the short side.

  For this reason, the discriminating unit 14 rotates each of the transport rollers 31, 32, 33, 35, 37, and 39 (hereinafter collectively referred to as a discrimination transport roller group), so that the banknote is always one of the transport rollers. Can be transferred to each other while being sandwiched between them, and can be transported along the transport path W1, W2 or W3.

[3-2. Configuration of each detector]
In the magnetic detection unit 34, a magnetic sensor 34A is disposed above the transport path W1, and a contact roller 34B is disposed below the transport path W1. The magnetic sensor 34A detects magnetism from the banknote when a banknote transported along the transport path W1 by the differential transport roller group is pressed by the contact roller 34B, and the detection result is detected by the banknote control unit 11 (FIG. 2). To send.

  This magnetic sensor 34A has a relatively high sensitivity in order to detect weak magnetism contained in a bill. For this reason, when there is a member that generates magnetism or a member that rotates or moves in a magnetized state around the magnetic sensor 34A, the magnetic sensor 34A is affected by the magnetism and may not be able to correctly detect the magnetism of the banknote. .

  The light emission detection unit 36 includes optical modules 36A and 36B that are arranged so as to face each other with the conveyance path W1 interposed therebetween in the vertical direction. The optical modules 36 </ b> A and 36 </ b> B are configured similarly to each other, and incorporate a light emitting element that emits light, such as an LED (Light Emitting Diode), and a light receiving element that receives this light. The optical modules 36A and 36B are arranged so that one light emitting element and the other light receiving element face each other. Incidentally, the light receiving element is an imaging element formed linearly along the left-right direction.

  The light emission detector 36 detects transmitted light and reflected light on both sides of the banknote transported on the transport path W1 by simultaneously or sequentially performing light emission and light reception in both the optical modules 36A and 36B. The detection result is sent to the banknote control unit 11 (FIG. 2). In this connection, this detection result is obtained by imaging a banknote in a straight line along the left-right direction, and by connecting these along the transport direction, a planar image obtained by imaging the banknote can be obtained.

  The banknote control unit 11 is either a genuine banknote (so-called genuine note) or a counterfeit (so-called counterfeit) based on the detection results supplied from the magnetic sensor 34A and the light emission detection unit 36, respectively. And the denomination and degree of damage.

  The thickness detector 38 includes a movable roller 38A attached to the upper conveyance guide 30A so as to be movable in the vertical direction, a fixed roller 38B attached to the lower conveyance guide 30B and not movable in the vertical direction, and the vertical direction of the movable roller 38A. And a movement amount sensor 38C for detecting the movement amount to the.

  When the bill is transported by the transport roller 37 or the rear portion 21B, the thickness detection unit 38 sandwiches the bill between the movable roller 38A and the fixed roller 38B. At this time, the movable roller 38A moves upward by an amount of movement corresponding to the thickness of the sandwiched banknote. The movement amount sensor 38C detects the movement amount of the movable roller 38A and notifies the banknote control unit 11 (FIG. 2) of the detection result as the banknote thickness.

  Based on the detection result supplied from the thickness sensor, the banknote control unit 11 corresponds to the thickness of the banknotes being conveyed on the conveyance path W1, is equivalent to one sheet, or two sheets. It is judged whether it corresponds to the above. Thereby, the banknote control part 11 is not conveying a banknote, is normally conveying only one banknote, or is conveying two or more banknotes piled up (namely, is carrying out multiple feeding). Can be recognized.

  Here, the movable roller 38A and the fixed roller 38B are made of a material that is not easily deformed, for example, a metal material, in order to accurately detect the thickness of a very thin banknote such as about 0.1 mm. However, such a metal material often has magnetism, and there is a risk of changing the surrounding magnetic field with its rotation.

  Therefore, in the discrimination unit 14, the light emission detection unit 36 is disposed between the magnetic detection unit 34 and the thickness detection unit 38, and the magnetic detection unit 34 and the thickness detection unit 38 are separated as much as possible in the front-rear direction, thereby moving the movable roller. The influence of magnetism on the magnetic sensor 34A of the magnetic detection unit 34 by the 38A and the fixed roller 38B is suppressed as much as possible.

[3-3. Configuration of reject switching unit]
As shown in FIG. 5, the reject switching unit 23 is roughly composed of a rotary actuator 41, a blade 42, and a magnetic shield 43.

  As shown in the enlarged side view of FIG. 6A, the rotary actuator 41 includes a solenoid coil 46 incorporated in a frame 45 that covers the periphery, and an output shaft 47 that penetrates the inside and outside of the frame. It has become the composition.

  The frame 45 is made of a metal material having magnetism, and is formed into a flat box shape that is relatively thin in the left-right direction by processing a plate-like member, and a space is provided therein. The solenoid coil 46 is a so-called electromagnet, and generates a magnetic force when supplied with electric power. That is, the frame 45 has a function of protecting the parts of the rotary actuator 41 from the outside and shielding the magnetism generated by the solenoid coil 46 to some extent.

  A power transmission mechanism (not shown) is incorporated in the frame 45. The power transmission mechanism incorporates a magnet that can move in the front-rear direction, a member that rotates according to the position of the magnet, and the like. For this reason, this power transmission mechanism converts the magnetic force generated in the solenoid coil 46 into a driving force in the rotational direction and transmits it to the output shaft 47.

  The output shaft 47 is formed in a relatively short columnar shape with the central axis directed in the left-right direction, and rotates around the central axis within a range of, for example, about 45 degrees by the driving force transmitted from the transmission mechanism. The right end of the output shaft 47 protrudes to the left of the left side surface of the frame 45, that is, outward.

  Further, as shown in FIG. 7, the rotary actuator 41 aligns the vertical position (that is, the height) of the center axis of the output shaft 47 with the substantially vertical center of the transport path W1.

  Furthermore, as shown in FIG. 8, the rotary actuator 41 has the solenoid coil 46 positioned almost directly below the output shaft 47. In other words, the solenoid coil 46 is located on the opposite side of the magnetic sensor 34A across the transport path W1. For this reason, the distance L2 from the magnetic sensor 34A to the solenoid coil 46 is longer than the distance L1 from the magnetic sensor 34A to the output shaft 47.

  The blade 42 (FIG. 5) is formed in a triangular prism shape with the central axis directed in the left-right direction as a whole, and has an isosceles triangle shape or wedge shape with the apex angle directed in the rear direction when viewed from the left-right direction. The blade 42 is penetrated in the left-right direction by the shaft 48 at a position near the center as viewed from the left-right direction.

  The shaft 48 is made of a magnetic metal material, and is formed in an elongated cylindrical shape with the central axis directed in the left-right direction. The shaft 48 is supported by the conveyance guide 30 via a bearing 49 at the right end.

  The shaft 48 is connected to the output shaft 47 through the connecting member 50 at the left end. For this reason, like the output shaft 47, the shaft 48 and the connecting member 50 are positioned so that the vertical position (that is, the height) is substantially aligned with the vertical center of the transport path W1 (FIG. 7). The connecting member 50 is made of, for example, a resin material, and is physically connected without directly contacting the output shaft 47 and the shaft 48, that is, in a state where they are separated on the magnetic circuit.

  As described above, the blade 42 is integrated with the shaft 48, the connecting member 50, and the output shaft 47. For this reason, the blade 42 can rotate around the shaft 48 together with the output shaft 47 of the rotary actuator 41.

  Specifically, as shown by the solid line in FIG. 7, the blade 42 is rotated so that the apex angle is positioned downward, so that the upper surface thereof is continuous with the upper surface of the lower transport guide 30B, and the transport path W1 and the transport path W2 And connect. Further, as shown by a broken line in FIG. 7, the blade 42 is rotated so that the apex angle is positioned upward, so that the lower surface thereof is continuous with the lower surface of the upper transport guide 30A, and the transport path W1 and the transport path W3 are connected. Connect.

  In this way, the reject switching unit 23 rotates the blade 42 by the rotary actuator 41 to connect the transport path W1 and the transport path W2 or connect the transport path W1 and the transport path W3. The transport route is switched.

  On the other hand, the magnetic shield 43 is formed in a rectangular cylinder covering the front, rear, left and right of the rotary actuator 41, and the upper surface and the lower surface thereof are open. The magnetic shield 43 is configured by bending a metal plate member having magnetism, for example, a steel plate having a thickness of about 2 to 3 mm.

  As shown in FIG. 6B, the magnetic shield 43 has an upper end that is higher than the upper end of the frame 45 in the rotary actuator 41 and a lower end that is lower than the lower end of the frame 45. The actuator 41 is covered. That is, the magnetic shield 43 covers a range wider than the frame 45 of the rotary actuator 41 in the vertical direction.

  Further, an insertion hole through which the output shaft 47 is inserted is formed on the upper side of the left side plate of the magnetic shield 43. Incidentally, the inner diameter of the insertion hole is sufficiently larger than the outer diameter of the output shaft 47, and the magnetic shield 43 and the output shaft 47 are avoided from contacting each other on the magnetic circuit.

  The magnetic shield 43 is fixed to the left side surface of the frame 45 of the rotary actuator 41 via the attachment member 51 on the inner surface (right surface) of the left side plate. The attachment member 51 is made of a nonmagnetic resin material. Further, the magnetic shield 43 is fixed to the right side surface of the conveyance guide 30 on the outer surface (left surface) of the left side plate. As described above, the transport guide 30 is made of a nonmagnetic resin material.

  For this reason, the magnetic shield 43 is separated on the magnetic circuit from any of the conveyance guide 30, each member attached thereto, and the frame 45 of the rotary actuator 41.

[4. Deposit process and withdrawal process]
Next, the banknote depositing and dispensing process in the banknote depositing and dispensing machine 10 will be described in detail with reference to FIGS. 9, 10, and 11. 9, 10, and 11 are enlarged views of the deposit / withdrawal unit 12, the transport unit 13, the discrimination unit 14, and the temporary storage unit 15 in the upper block 10 </ b> U of the banknote depositing / dispensing machine 10. .

[4-1. Deposit processing]
First, a case where a customer (user) performs a deposit process for depositing banknotes into the automatic teller machine 1 will be described with reference to FIGS. 9 and 10. The banknote depositing / dispensing machine 10 performs a depositing counting process of counting the number of sheets while discriminating the denominations of the banknotes deposited in advance in the depositing process based on the control of the banknote control unit 11, and A deposit storage process is carried out for transporting to the storage location and storing.

  Specifically, for example, when the banknote control unit 11 receives an operation input for starting the deposit process via the operation display unit 6 (FIG. 1) by the customer, the bill control unit 11 starts the deposit counting process and the shutter 12 </ b> B of the deposit / withdrawal unit 12. Is opened and bills are inserted into the container 12A. Next, if the banknote control part 11 receives the operation input which starts taking in of a banknote via the operation display part 6, the shutter 12B will be closed and the banknote in the said container 12A will be isolate | separated into one sheet at a time by 12C Then, it is sequentially transferred to the first transport unit 21 of the transport unit 13 by the deposit / withdrawal transport unit 12E.

  The 1st conveyance part 21 delivers the banknote delivered from the deposit or withdrawal part 12 sequentially back by the rejection switching part 23 of the discrimination part 14. FIG. Moreover, the discrimination part 14 discriminates each banknote sequentially by each sensor, conveying a banknote back inside, and delivers the said banknote to the rear part 21B of the 1st conveyance part 21 from a back side, and the discrimination result is a banknote. It is sent to the control unit 11.

  The banknote control unit 11 first determines the degree of damage, denomination, or authenticity of each banknote based on the acquired discrimination result. Next, the banknote control unit 11 is a deposit acceptance banknote that can be recognized as a normal banknote for each banknote and can continue the subsequent processing, or is a deposit reject banknote that should be returned to the customer once because it cannot be recognized as a normal banknote. Determine whether.

  Moreover, the banknote control part 11 carries out the rejection store | warehouse | chamber 16 about the reject banknote with a large degree of damage about a receipt banknote, each banknote storage 17 for every denomination about a normal and reusable banknote, and a fake ticket. Are determined as final transport destinations, respectively.

  Next, the 1st conveyance part 21 switches the conveyance path | route by the 1st switching part 24, and as shown by arrow Q1, the banknote delivered from the discrimination part 14 is conveyed back by the rear part 21B, and is temporarily hold | maintained switching part 20 Sequentially delivered to.

  The temporary hold switching unit 20 switches to the conveyance path according to the discrimination result for each banknote based on the control of the banknote control unit 11. Specifically, the temporary holding switching unit 20 advances and stores the deposit acceptance banknote and the counterfeit bill to the upper temporary holding unit 15 as indicated by the arrow Q2, and indicates the deposit reject banknote BL by the arrow Q3. In this way, it is advanced into the second transport unit 22 and stored in the transport path storage unit 22S.

  Eventually, when the banknote control unit 11 finishes taking in all banknotes from the container 12A of the deposit / withdrawal unit 12, if the deposit reject banknote BL is stored in the transport path storage unit 22S, this is indicated by an arrow Q4. It is conveyed to the deposit / withdrawal unit 12 (that is, reversely sent), returned to the customer, and confirmed and re-entered. On the other hand, the banknote control unit 11 completes the deposit counting process if the deposit reject banknote BL is not stored in the transport path storage unit 22S.

  At this time, the banknote control unit 11 calculates the deposit amount based on the total result of the denomination and the number of the banknotes taken in from the deposit / withdrawal unit 12 and displays a predetermined operation instruction screen on the operation display unit 6. The amount of money is presented to the customer and the customer is allowed to select whether or not to continue the deposit process.

  Here, the banknote control unit 11 sequentially receives all banknotes held in the temporary holding unit 15 by the temporary holding switching unit 20, the first transport unit 21, and the discrimination unit 14 when the customer instructs to stop the deposit process. It is conveyed forward and returned into the container 12A of the deposit / withdrawal unit 12, and the shutter 12B is opened and returned to the customer.

  On the other hand, when the continuation of the deposit process is instructed by the customer, the banknote control unit 11 starts the deposit storage process as shown in FIG. Specifically, the banknote control unit 11 first starts the maneuvering process in the temporary storage unit 15 to sequentially feed out the stored banknotes (payment acceptance banknotes) as indicated by the arrow Q5, and the temporary temporary storage switching downstream. Delivered to part 20.

  Moreover, the banknote control part 11 switches the conveyance path | route of the temporary holding | maintenance switching part 20 according to the conveyance destination for every banknote determined in the money_receiving | payment count process. That is, the temporary hold switching unit 20 delivers the banknote to the downstream first transport unit 21 if the transport destination is the reject store 16 or the banknote storage 17A, and the transport destination is the banknote storage 17B-17E or the fake ticket store 18. If there is, the transport path is switched so that the banknote is delivered to the second transport section 22 downstream.

  Furthermore, the banknote control part 11 conveys the said banknote to the said conveyance destination, and each accommodates it by controlling suitably each switching part of the 1st conveyance part 21 and the 2nd conveyance part 22 according to the conveyance destination of each banknote. . Thereby, the banknote control part 11 stores the reject banknote which should not be reused in the rejection store | warehouse | casing 16 as shown by arrow Q7, and classifies the normal banknote which should be reused for every money type as shown by arrow Q6. The banknotes stored in each banknote storage 17 and banknotes determined to be counterfeit can be stored in the counterfeit storage 18.

  In this way, the banknote depositing / dispensing machine 10 stores the banknotes in the temporary storage unit while determining the transport destination of each banknote when the banknotes are identified in the preceding deposit counting process in the depositing process, and is instructed to continue the depositing process. In the subsequent deposit storage process, each banknote is transported to a transport destination that has already been determined.

[4-2. Withdrawal processing]
Next, the case where the customer performs a withdrawal process for withdrawing banknotes from the automatic teller machine 1 will be described with reference to FIG. In the withdrawal process, the banknote depositing and dispensing machine 10 performs a withdrawal process for dispensing a denomination and the number of banknotes according to the designated amount based on the control of the banknote control unit 11.

  Specifically, the banknote control unit 11 first receives a predetermined operation input including a withdrawal amount from the customer via the operation display unit 6 (FIG. 1), and determines the denomination and the number of banknotes according to the withdrawal amount. Subsequently, the banknote control unit 11 pays out the banknotes stored in a state of being accumulated in each banknote storage 17 according to the determined denomination and number, and separates the banknotes one by one for downstream first conveyance. The paper is sequentially transferred to the unit 21 or the second transport unit 22.

  At this time, the banknote control unit 11 appropriately forwards the banknotes stored in the banknote storages 17B to 17E by appropriately switching the switching units of the second transport unit 22 as indicated by an arrow Q8, and temporarily holding the banknotes. The first transfer unit 21 is transferred via the switching unit 20. Further, the banknote control unit 11 stores the banknote stored in the banknote storage 17A once in the temporary storage unit 15 via the temporary storage switching unit 20, as indicated by the arrow Q9, and then as indicated by the arrow Q10. Next, the temporary storage unit 15 is sequentially advanced to advance forward in the first transport unit 21.

  Next, the banknote control part 11 discriminate | determines the banknote which advances the inside of the 1st conveyance part 21 by the discrimination part 14, and sends the discrimination result to the banknote control part 11 (FIG. 2). In response to this, the banknote control unit 11 determines the transport destination as the deposit / withdrawal unit 12 or the reject box 16 according to the discrimination result of the banknote.

  Specifically, if there is no problem in the running state of the banknote, the banknote control unit 11, as shown in FIG. 13, the upper deposit / withdrawal unit 12 and the rear discrimination unit in the reject switching unit 23 of the first transport unit 21. 14 is formed, and as shown by an arrow Q11, the banknote is conveyed to the downstream depositing / dispensing portion 12 and discharged into the container 12A.

  On the other hand, if there is a problem in the running state of the banknote, for example, the banknote control unit 11 is double-feeded, the reject switching unit 23 connects the rear discrimination unit 14 and the lower reject box 16. A path is formed, and the bill is conveyed to and stored in the downstream reject box 16 as indicated by an arrow Q12.

  By the way, the discrimination unit 14 detects the running state by the thickness detection unit 38 located on the upstream side, sends the detection result to the banknote control unit 11 (FIG. 2), and then the light emission detection unit 36 located on the downstream side. And the detection result by the magnetic detection part 34 is sent to the banknote control part 11. FIG. That is, the banknote control part 11 acquires the detection result by the light emission detection part 36 and the magnetic detection part 34, after determining the conveyance destination of each banknote according to a driving | running state by the thickness detection part 38. FIG.

  Therefore, when the bill control unit 11 detects that the bill is not normal and should not be dispensed by the light emission detection unit 36 and the magnetic detection unit 34, as shown by an arrow Q13 in FIG. The banknote being conveyed is stopped immediately, that is, in the middle of being conveyed by the depositing / dispensing conveyance unit 12E of the discrimination unit 14 or the depositing / dispensing unit 12. Further, as shown by an arrow Q14 in FIG. 14B, the banknote control unit 11 reversely feeds the banknote to reach the rear side of the discrimination unit 14, and then sets the transport destination of only the banknote in the reject box 16. Then, the reject switching unit 23 is switched and conveyed to the reject box 16 as indicated by an arrow Q15.

  Eventually, when the banknote control unit 11 finishes releasing all the banknotes corresponding to the withdrawal amount into the container 12A of the depositing and dispensing unit 12, the shutter 12B is opened and the customer takes out the banknotes.

  In this way, the banknote depositing / dispensing machine 10 deposits / withdraws banknotes according to the withdrawal amount from each banknote storage 17 while switching the transport path by the reject switching unit 23 based on the discrimination result by the discrimination unit 14 in the withdrawal process. It is transported to the section 12 and delivered to the customer.

[5. Operation and effect]
In the above configuration, the banknote depositing and dispensing machine 10 of the automatic teller machine 1 incorporates the discrimination unit 14 in the first transport unit 21 located on the front side of the transport unit 13. In the discrimination unit 14, a discrimination conveyance roller group and a plurality of detection units are arranged, and in addition to this, a reject switching unit 23 is arranged.

  In particular, in the discrimination unit 14, the thickness detection unit 38 is arranged on the rearmost side in order to detect an abnormality in conveyance such as double feeding at the earliest stage in the withdrawal process. Moreover, in the discrimination part 14, in order to suppress the influence of the magnetism from the thickness detection part 38, the magnetic detection part 34 is arrange | positioned at the front side which is the other side. As a result, in the discrimination unit 14, the rotary actuator 41 of the reject switching unit 23 and the magnetic sensor 34 </ b> A that may be affected by magnetic noise are arranged at relatively close positions.

  In addition to this, in the banknote depositing / dispensing machine 10, in order to keep the overall longitudinal length short, the length in the longitudinal direction of the first conveyance unit 21 of the conveyance unit 13 is set in the discrimination unit 14 in order to meet the demand for minimization as much as possible. The reject switching unit 23 is arranged in the area.

  For this reason, in the discrimination unit 14, the rotary actuator 41 of the reject switching unit 23 is disposed at a location relatively close to the magnetic sensor 34 </ b> A of the magnetic detection unit 34. Therefore, the magnetic sensor 34A may detect the magnetism generated by the solenoid coil 46 in the rotary actuator 41 as magnetic noise.

  In this respect, in the discrimination unit 14, a magnetic shield 43 is disposed so as to surround the front, rear, left and right of the rotary actuator 41 in the reject switching unit 23 (FIG. 5). Thereby, the discrimination part 14 can shield effectively the magnetism which generate | occur | produces with the solenoid coil 46 with the magnetic shield 43, and can reduce significantly possibility that it will influence magnetic sensor 34A as a magnetic noise.

  From another point of view, the discrimination unit 14 can arrange the rotary actuator 41 and the magnetic sensor 34A closer to each other by arranging the magnetic shield 43. This can contribute to downsizing and further downsizing of the banknote depositing and dispensing machine 10 and the automatic teller machine 1.

  In the discrimination unit 14, the magnetic shield 43 is provided by the mounting member 51 so as to be spaced apart from the frame 45 of the rotary actuator 41 by a certain distance. For this reason, the discrimination part 14 can suppress the fall of the magnetic shielding effect by making it hard to generate | occur | produce magnetic saturation in the magnetic shield 43. FIG.

  Further, in the discrimination unit 14, the magnetic shield 43 is directly brought into contact only with the resin conveyance guide 30 and the mounting member 51, and is not brought into contact with other members, particularly a metal member having magnetism. For this reason, the discrimination part 14 can isolate | separate the magnetic shield 43 from another member on a magnetic circuit, and can suppress effectively that the magnetism of the solenoid coil 46 leaks outside.

  By the way, the discrimination unit 14 inevitably determines the position of the blade 42 with respect to the transport paths W1, W2, and W3, and accordingly, the positions of the shaft 48 and the output shaft 47 are also determined. Moreover, in the discrimination part 14, the rejection switching part 23 is arrange | positioned in the front end, and as mentioned above, from a viewpoint of restraining the front-back length of the banknote depositing / withdrawing machine 10 as short as possible, the solenoid coil is located in front of the shaft 48 and the output shaft 47. 46 is difficult to arrange.

  Therefore, in the discrimination unit 14, the solenoid coil 46 is positioned almost directly below the output shaft 47 in the rotary actuator 41. This means that the solenoid coil 46 is disposed at a position farthest from the magnetic sensor 34A among positions that can be disposed under various restrictions in the discrimination unit 14. For this reason, the discrimination part 14 can suppress the influence of the magnetism exerted on the magnetic sensor 34A from the solenoid coil 46 to the minimum.

  Further, the magnetic shield 43 is arranged in the discrimination portion 14 to be configured as small as possible so as to be spaced apart from each other in the front, rear, left, and right directions from the frame 45 of the rotary actuator 41 (FIG. 5). For this reason, the magnetic shield 43 is less likely to cause magnetic saturation as compared with the case where the magnetic shield 43 is disposed in the immediate vicinity of the frame 45, and a part of the magnetism can be returned to the frame 45 side without reaching the magnetic shield 43. it can.

  Accordingly, the magnetic shield 43 does not require a structure that enhances the magnetic shielding effect more than necessary, such as using a material with high magnetic permeability or processing a plate-like member having a large thickness. The required cost can be kept low.

  According to the above configuration, the banknote depositing and dispensing machine 10 of the automatic teller machine 1 incorporates the discrimination unit 14 in the first conveyance unit 21 located on the front side of the conveyance unit 13, and the discrimination conveyance roller group in the discrimination unit 14. In addition, a plurality of detection units are arranged, and in addition to this, a reject switching unit 23 is arranged. In the reject switching unit 23, a magnetic shield 43 is disposed so as to surround the front, rear, left and right of the frame 45 in the rotary actuator 41. As a result, the discrimination unit 14 is forced to place the rotary actuator 41 at a location relatively close to the magnetic sensor 34A of the magnetic detection unit 34 due to size and arrangement restrictions. However, the magnetism generated by the solenoid coil 46 is magnetically shielded. 43 can be effectively shielded, and the possibility of affecting the magnetic sensor 34A as magnetic noise can be greatly reduced.

[6. Other Embodiments]

  However, the present invention is not limited to this. For example, the solenoid coil 46 may be disposed at a position substantially off from directly below the output shaft 47, or the solenoid coil 46 may be located above the transport path W1, that is, the same as the transport path W1. It may be arranged on the side. In this case, the distance L2 may be smaller than the distance L1. In these cases, it is only necessary that the magnetic shield 43 can sufficiently reduce the influence of magnetism from the rotary actuator 41 to the magnetic sensor 34 </ b> A.

Said. However, the present invention is not limited to this. For example, a hollow prismatic mounting member that fills a gap with the magnetic shield 43 on each of the front, rear, left, and right sides of the frame 45 is configured, and the frame 45 is connected to the frame 45 via the mounting member. On the other hand, the magnetic shield 43 may be fixed. In this case, the magnetic shield 43 may not be fixed to the transport guide 30.

The case where the lower end of the magnetic shield 43 is made lower than the lower end of the frame 45 has been described. However, the present invention is not limited to this. For example, when the magnetic shielding effect by the magnetic shield 43 is high, the magnetic field generated by the solenoid coil 46 is shielded only by the magnetic shield 43 by configuring the frame 45 with a nonmagnetic material. In addition, the upper end of the magnetic shield 43 may be lower than the upper end of the frame 45, and the lower end of the magnetic shield 43 may be higher than the lower end of the frame 45.

  Furthermore, in the above-described embodiment, the case where the upper and lower portions of the magnetic shield 43 are opened and the magnetism is shielded only on the front, rear, left and right side surfaces has been described. However, the present invention is not limited to this. For example, the upper and lower portions of the magnetic shield 43 may be closed.

Further, in the above-described embodiment, the case where the shaft 48 is made of a magnetic material and is connected by the connecting member 50 made of a nonmagnetic material so that the shaft 48 and the output shaft 47 are not in direct contact with each other has been described. However, the present invention is not limited to this. For example, the shaft 48 may be made of a nonmagnetic material, and the shaft 48 and the output shaft 47 may be connected by the connecting member 50.

  Furthermore, in embodiment mentioned above, the case where this invention was applied to the automatic teller machine 1 which performs transaction processing of a banknote between users was described. However, the present invention is not limited to this.
