8 to 13 show the relationship between the height guide 11, the width guide 50, the drive unit 60, and the movable cam 70, which are the main parts of the bill processing apparatus 100, and the outer shell of the case 1 and the bill Illustration of the storage unit 40 is omitted.

  As shown in FIGS. 1 to 7, the bill processing apparatus 100 has a bill insertion unit 10 for inserting a bill B (not shown) in the upstream U, and a bill storage unit 40 for stacking and storing the bills B in the downstream D. And a bill conveyance means 30 for conveying the bill B along the bill conveyance passage part 20. The bill B inserted into the bill insertion unit 10 is transported by the bill transport means 30 from the upstream U to the downstream D along the bill transport passage portion 20 under specific conditions, and under the specific condition, the bill transport means At 30, the paper sheet is transported from the downstream D toward the upstream U along the bill transport passage portion 20.

The bill processing apparatus 100 is inserted when the bill width of the bill B inserted from the bill insertion unit 10 is within a preset range in a region where a plurality of kinds of bills B having different bill widths circulate. The banknotes B are stacked and stored in the banknote storage unit 40.
For example, a combination of banknote types and banknote widths distributed as renminbi in China is 100 yuan bills (77 mm), 50 yuan bills (70 mm), 20 yuan bills (70 mm), 10 yuan bills (70 mm), 5 There are 5 square notes (59 mm) and 1 square note (52 mm) in addition to the original notes (63 mm) and 1 original note (63 mm), but the note processing apparatus 100 has a note width of 77 mm, 70 mm or 63 mm. Accept and store the original bill. That is, it is possible not to store without receiving a square bill whose bill width is less than 63 mm.

  The structure of the bill processing apparatus 100 will be described. Specifically, as shown in FIG. 1, the bill insertion unit 10, the bill conveyance passage unit 20, the bill conveyance means 30, and the bill storage unit 40 of the bill processing apparatus 100 are respectively It is supported by a case 1 and integrally assembled.

(Banknote insertion part)
The bill insertion portion 10 has a height guide 11 capable of reciprocating in the vertical direction and a receiving guide 12. The bill insertion portion 10 defines an insertion slot 10 a between the height guide 11 and the receiving guide 12 into which the bill B is inserted.

  As shown in FIG. 4, the dimension β in the height direction of the insertion slot 10 a defined by the bill insertion unit 10 stabilizes the posture toward the bill conveyance passage portion 20 located downstream of the insertion slot 10 a. In order to guide as it is, in the normal state, it is slightly larger than the thickness of the bill B and smaller than the dimension α in the height direction of the bill transport passage portion 20.

  The bill insertion portion 10 has the height guide 11 capable of reciprocating in the vertical direction, and the height guide 11 can reciprocate between the normal position and the insertion port enlargement position. The dimension (beta) of the height direction of the insertion opening 10a prescribed | regulated becomes variable between a normal state and the insertion opening enlarged state larger than a normal state. Therefore, for example, when sending out the bill B which is deformed in a bellows-like shape and the height dimension is increased, the bill B is set by enlarging the dimension β in the height direction of the insertion slot 10a from the normal state. Contact with the height guide 11 causes resistance to discharge, and as a result, clogging of the inside of the bill conveyance passage portion 20 can be suppressed, and the deformed bill B can be returned.

  The receiving guide 12 may be a part of the case 1 as shown in FIG. 13, or may be a separate body fixed to the case 1. The receiving guide 12 has a width slightly larger than the bill width of the accepted bill B. On the upper surface of the receiving guide 12, in order to reduce resistance to the bill B, a plurality of ribs 12r that extend along the direction of inserting the bill B and are curved toward the insertion port 10a are provided.

  The height guide 11 has a width equal to the largest bill width among the bills B used, as shown in FIGS. 13 and 18. The width of the height guide 11 is smaller than the width of the receiving guide 12 in order to make the whole bill processing apparatus 100 compact. In the state other than the insertion opening enlargement state, the height guide 11 includes the shaft support portion 11 a pivotally supported by the case 1, the height guide engagement portion 11 p engaged with the movable cam engagement portion 74 of the movable cam 70. And a stopper 11 s supported by the case 1. The bearing 11 a and the stopper 11 s are provided at both ends of the height guide 11. The stopper 11s pivots in the direction in which the insertion opening 10a expands (the direction indicated by the arrow θ in FIG. 11B) in a state where the height guide 11 is supported by the shaft support 11a. Although it is possible, it is engaged with the case 1 so that it can only swing to a predetermined position in the opposite direction. Therefore, in the height guide 11, in the state other than the insertion port enlargement state, that is, the state from the normal state to the passage width 71 mm state to the passage width 64 mm state, the axially supporting portion 11 a is supported with respect to the case 1, The stopper 11s is supported, and the position of the height guide 11 is maintained at the normal position.

  The height guide 11 reciprocates in accordance with the vertical movement of the movable cam 70. This will be described later.

  In addition, the bill insertion portion 10 has a width detection sensor (not shown) for detecting the width of the inserted bill B. Specifically, the width detection sensors are, for example, optical sensors that are arranged along the width direction on both sides of the insertion slot 10 a in the bill insertion unit 10. The width detection sensor may be disposed at an end of the bill conveyance passage unit 20 on the bill insertion portion side. The optical sensor has, for example, a light emitting unit and a light receiving unit, the light emitting unit is disposed on one side in the vertical direction in the insertion slot 10a, the light receiving unit is disposed on the other side, and light emitted from the light emitting unit is the insertion slot 10a. In the vertical direction to reach the light receiving unit. The optical sensors are arranged side by side in the lateral direction (passage width direction) at a pitch of 1 mm, for example. As described above, the width detection sensor is not disposed at the central portion of the insertion slot 10a in the bill insertion portion 10, but is collectively disposed on both sides, so that the bill widths differ even if many optical sensors are not disposed. While being able to identify a plurality of types of banknotes B, it is possible to identify banknotes and the like having a width not within the preset range.

(Banknote conveyance passage)
The bill conveyance passage portion 20 is a portion including a passage (space) through which the bill B inserted from the bill insertion portion 10 reaches the bill storage portion 40. The bill insertion portion 10, the bill transport means 30, and the bill storage portion 40 are provided along the bill transport passage portion 20. As schematically shown in FIG. 4, the bill conveyance passage part 20 includes a horizontal part 21 extending in the lateral direction from the bill insertion part 10, a bending part 22 curving upward from there, and a vertical part extending in the vertical direction. And 23. Here, the width direction of the passage in the lateral portion 21 and the curved portion 22 is variably defined by the width guide 50. The height direction of the passage in the bill transport passage portion 20 and the width direction of the vertical portion 23 are defined by the case 1.

(Note transfer means)
The bill conveying means 30 includes, for example, a drive source (not shown) and a rubber belt (not shown) which is wound around a pulley (not shown) connected to the drive source and has a large friction with the bill B. . The bill conveyance means 30 may use the drive unit 60 as a drive source. As shown in FIG. 4, the bill conveyance means 30 is provided along a part (horizontal part 21 or curved part 22) excluding a part (vertical part 23) along the bill storage part 40 in the bill conveyance passage part 20. As a result, the bill B transported from the upstream U to the downstream D receives a vertically upward force by the bill transport means 30, and when it reaches the vertical portion 23, the bill B is directed from the upper side to the upstream U of the bill B. The pulling force does not act, and a state in which only the lower end portion is supported in the passage of the bill conveyance passage portion 20, in other words, a state in which the bill B stands up is obtained. Therefore, when the bill B is deformed when the bill B reaches the vertical portion 23, the length of the bill B becomes shorter than the original length, so that the bill B is provided at a position where the original bill B reaches. Note that the bill B conveyed to the vertical portion 23 is not a prescribed bill because a part of the passage sensor 80 (for example, the left passage sensor 83L or the right passage sensor 83R in FIGS. 2 and 6) does not detect the bill B Can detect
Further, the bill conveyance means 30 may be provided also in a part along the bill storage part 40 in the bill conveyance passage part 20. As a result, the bill B transported from the upstream U to the downstream D receives the force in the vertically upward direction by the bill transport means 30 and reaches the vertical portion 23. Then, a force for pulling the bill B from the upper side of the bill B toward the upstream U acts from the bill transport means 30 provided in a portion along the bill storage portion 40, and the bill B becomes difficult to deform in the compression direction. The risk of clogging in the transport passage 20 is reduced. Therefore, the number of passage sensors 80 for detecting clogging of the bill B can be reduced.

(Relationship between drive unit and movable cam)
The bill processing apparatus 100 includes a drive unit 60 and a movable cam 70 that moves up and down according to the movement of the drive unit 60.
Then, the height guide 11 of the bill insertion portion 10 reciprocates in the vertical direction in accordance with the vertical movement of the movable cam 70. In addition, this reciprocating motion includes a lifting and lowering motion and a swing motion around the shaft support portion 11a. As described above, since the height guide 11 reciprocates in accordance with the up and down movement of the movable cam 70 accompanying the movement of the drive unit 60, the bill B is fed out from the downstream D to the upstream U by the bill transport means 30. By controlling the drive unit 60, the height guide 11 can be moved to the upper position in the vertical direction from the normal position, and the dimension in the height direction of the insertion port 10a can be made larger than the normal state. Therefore, it can suppress that the banknote B is clogged in the inside of the banknote conveyance passage part 20, and the changed banknote B can be returned.

  The drive unit 60 includes an electric motor 61 having an output shaft 61a, a worm shaft 62 interlocked with the rotation of the output shaft 61a, and a worm wheel 63 interlocked with the rotation of the worm shaft 62.

  The bill processing apparatus 100 includes a pulse sensor 61s (see FIGS. 10 and 11) that emits a pulse according to a change in the rotational position (rotational angle) of the electric motor 61. The control device controls the rotational position (rotational angle) of the electric motor 61 by the pulse generated by the pulse sensor 61s.

  When the electric motor 61 rotates, the output shaft 61a, the worm shaft 62, and the worm wheel 63 interlock and rotate.

As shown in FIG. 15, the worm wheel 63 has a wheel engagement portion 63p that protrudes in the direction along the rotation center axis at a position eccentric from the rotation center axis. The wheel engagement portion 63 p engages with a laterally long cam engagement groove 72 provided on the movable cam 70.
Thus, when the worm wheel 63 rotates, the wheel engagement portion 63p acts on the cam engagement groove 72 to move the movable cam 70 in the vertical direction. And since the guide groove 73 of the movable cam 70 is engaged with the guide rail (not shown) provided in the case 1, the movable cam 70 is interlocked with the rotation of the worm wheel 63 to be vertical. Move parallel to and move up and down.

As shown in FIGS. 13 and 14, the movable cam 70 has a cam groove 71 with which the left width guide engaging portion 51p and the right width guide engaging portion 52p engage, and a cam connector with which the wheel engaging portion 63p engages. A guide groove 73 which is engaged with and guided by a guide rail (not shown) provided in the case 1 and extends in the vertical direction, and a height guide engaging portion 11p of the height guide 11 And a movable cam engaging portion 74 to be engaged. The movable cam 70 has a cam groove 71 on the back and a cam engagement groove 72 on the front.
The movable cam 70 moves in parallel in the vertical direction because the guide groove 73 is engaged with and guided by the guide rail of the case 1.

  The cam engagement groove 72 is a laterally long groove and has a groove width slightly larger than the vertical dimension of the wheel engagement portion 63p. When the worm wheel 63 rotates, the position of the wheel engagement portion 63p rotates in a front view, and while the wheel engagement portion 63p pushes the upper or lower side of the inner wall of the cam engagement groove 72, it moves laterally in plan view. The movable cam 70 moves up and down.

  Specifically, when the wheel engagement portion 63p of the worm wheel 63 is positioned substantially at the center of the worm wheel 63 in the vertical direction, ie, positioned to the left or right of the rotational center of the worm wheel 63, the movable cam 70 Is the normal position (see FIG. 11 (a)), and when the wheel engagement portion 63p is positioned above the worm wheel 63 in the vertical direction, the movable cam 70 is in the insertion port enlargement position (see FIG. 11 (b)). When the wheel engagement portion 63p is positioned slightly below the worm wheel 63 in the vertical direction, the movable cam 70 has a passage width of 71 mm (see FIG. 11C), and the wheel engagement portion 63p corresponds to the worm wheel 63. When the movable cam 70 is positioned further downward in the vertical direction, the movable cam 70 has a passage width of 64 mm (see FIG. 11D). That.

  Thus, since the drive unit 60 moves the movable cam 70 up and down via the worm shaft 62 and the worm wheel 63, for example, external forces other than those by the drive unit 60 from the height guide 11 and the width guide 50 are movable. Even if it acts on the cam 70, the movable cam 70 is difficult to move due to the unidirectionality of the frictional resistance between the worm shaft 62 and the worm wheel 63. Therefore, the height guide 11 and the width guide 50 interlocked with the movable cam 70 are difficult to move. Accordingly, it is possible to prevent fraudulent acts such as pulling out the bill B.

  More specifically, the cam groove 71 of the movable cam 70 is a continuation of at least the oblique groove 70S and the vertical groove 70L as shown in (a) to (d) of FIG. 12 and FIG. Specifically, the cam groove 71 has a left-right symmetrical shape in rear view, and has a pair of vertical grooves 70L and a pair of oblique grooves 70S on the left and right. The pair of oblique grooves 70S is, for example, inclined at approximately 45 degrees with respect to the vertical direction. The uppermost portions of the respective oblique grooves 70S in the pair of oblique grooves 70S may or may not be connected and continuous with each other.

  The left width guide engagement portion 51p and the right width guide engagement portion 52p are engaged with the cam groove 71, and the left width guide engagement portion 51p and the right width guide engagement portion 52p approach or separate from each other. As the movable cam 70 moves up and down, the positions of the left width guide engaging portion 51p and the right width guide engaging portion 52p with respect to the cam groove 71 change, and accordingly, the movable cam 70 moves up and down. The left width guide engaging portion 51p and the right width guide engaging portion 52p approach and separate.

  As described above, since the cam groove 71 is symmetrical in the left-right direction, each of the left width guide engaging portion 51p and the right width guide engaging portion 52p can be moved left and right simply by moving the movable cam 70 in parallel in the vertical direction. It can be moved symmetrically.

  The movable cam engaging portion 74 is provided on the front end of the movable cam 70 at both ends of the movable cam 70. The movable cam engaging portion 74 is, as shown in detail in (a) to (d) of FIG. 11 and FIG. 14, a bulging portion 74 a that bulges from the back to the front, and from the front to the back The recess 74b is provided in the lower part of the bulging part 74a continuously with the bulging part 74a, and the recess 74b is continuously provided in the lower part of the recess 74b, and the front side from the bulging part 74a And a protruding portion 74c protruding to the

(Relationship between movable cam and height guide)
When the movable cam 70 is between the normal position (see FIG. 11 (a)) and the insertion port enlarged position (see FIG. 11 (b)), the height guide engaging portion 11p of the height guide 11 is the movable cam While in contact with any of the bulging portion 74a, the concave portion 74b, and the projecting portion 74c in the engaging portion 74, the movable cam 70 moves relative to the movable cam 70 that moves up and down.

  Specifically, when the movable cam 70 is in the normal position (see FIG. 11A), in the height guide 11, the height guide engaging portion 11p is in contact with the bulging portion 74a of the movable cam 70, and the insertion opening 10a becomes a normal position which becomes a usual height size. When the movable cam 70 is in the insertion opening enlargement position (see FIG. 11B), that is, when the movable cam 70 moves vertically upward from the normal position, the height guide engaging portion 11p of the height guide 11 is movable. When the movable cam 70 further moves vertically upward in contact with the projecting portion 74c of the cam 70 and the movable cam 70 further moves vertically upward, the height guide 11 is caused to swing about the pivot portion 11a to engage the height guide The portion 11p swings in the back direction to contact the recess 74b of the movable cam 70, the entire height guide 11 swings by a predetermined angle θ, and the insertion port enlargement position where the insertion port 10a is larger than the normal height dimension become.

  On the other hand, when the movable cam 70 is between the normal position (see FIG. 11A) and the passage width 64 mm (see FIG. 11D), that is, the movable cam 70 moves vertically downward from the normal position. Also, since the height guide 11 is supported by the bearing portion 11a and the stopper 11s, the height guide 11 maintains the same position as the normal position. That is, the height guide 11 is the same at the normal position (see FIG. 11A), at the passage width of 71 mm (see FIG. 11C), and at the passage width of 64 mm (see FIG. 11D). It becomes an attitude.

(Relationship between movable cam and width guide)
By the way, the bill conveyance passage portion 20 includes a pair of facing width guides 50 provided on both sides of the bill conveyance passage portion 20. The distance between the pair of width guides 50 and the passage width W of the bill conveyance passage portion 20 are steplessly variable according to the drive of the drive unit 60.

  Specifically, the width guide 50 includes a left width guide 51 and a right width guide 52 as shown in FIGS. 13, 16 and 17. The left width guide 51 and the right width guide 52 have substantially symmetrical shapes except for a part, and in order to be able to move parallel to each other in the lateral direction, for example, a rack 51g is arranged along the lateral direction in the left width guide 51 The right width guide 52 is provided with a rack 52g along the lateral direction so as to face the rack 51g. In addition, between the rack 51g and the rack 52g, for example, two pinions (not shown) are provided to enable smooth relative movement with low frictional resistance while maintaining the distance between the rack 51g and the rack 52g. It is arranged.

Further, as shown in (a) to (d) of FIG. 12, the left width guide 51 is provided with a left width restricting portion 51 w, and the right width guide 52 is provided with a right width restricting portion 52 w. The left width restricting portion 51w and the right width restricting portion 52w define the passage width W (see FIG. 12) of the bill conveyance passage portion 20.
The cross sections of the left width restricting portion 51 w and the right width restricting portion 52 w have uniform shapes orthogonal to the transport direction. In addition, the cross-sections of the left width restricting portion 51w and the right width restricting portion 52w are each formed by rotating the letter U of the alphabet by 90 degrees as shown in FIG. 12 (a) to (d) as a representative. One end is open and the other end is closed. The inner open end of each of the left width restricting portion 51w and the right width restricting portion 52w is substantially parallel to the upper surface with the inner surface facing in the vertical direction, and the inner surface is vertical in the closed end of the other end. It is straight to The left width restricting portion 51 w and the right width restricting portion 52 w are disposed such that the open portions at one end in each cross section face each other in the width direction (lateral direction).

Here, assuming that it is used in a region where Chinese renminbi is in circulation, the case where the bill width is set in the range of 63 mm to 77 mm will be described.
(1) First, the initial state of the banknote handling apparatus 100 is normal, the passage width W is the largest (see FIG. 12A), and the insertion port 10a is narrow (FIG. 11A) ))).
When the bill B is inserted into the insertion slot 10a, a part of a plurality of optical paths by a plurality of optical sensors in which the bills B are lined is blocked, and a part of the optical sensors detect that the optical path is blocked Do.
(2) The control device (not shown) calculates a parameter corresponding to the bill width or the bill width of the bill B based on the detected number and arrangement of optical sensors.
(3) The control device raises and lowers the movable cam 70 by controlling the rotational position (rotational angle) of the electric motor 61 of the drive unit 60 based on the calculated bill width of the bill B, and the pair of width guides The distance between the two 50, that is, the passage width W of the bill conveyance passage portion 20 is adjusted.
(4) At this time, if the control device determines that the bill width of the bill B falls within a preset range as a result of the calculation of the parameter corresponding to the bill width of the bill B or the bill width, the bill conveying means 30 The bill B is driven to be conveyed along the bill conveyance passage portion 20, and as a result of the calculation, the bill conveyance means 30 is not driven unless the bill width of the bill B is within the preset range.
Then, since the bill width of the bill B is set in advance in the range of 63 mm to 77 mm, the control device drives the bill conveying means 30 if the bill B is a 100 bill having a bill width of 77 mm. The position of the width guide 50 is maintained in the initial state (normal state) so that the width W becomes 78 mm obtained by adding a margin of about 1 mm to the bill width (see FIG. 12A). If the bill B is a 50 bill, a 20 bill or a 10 bill having a bill width of 70 mm, the bill transport means 30 is driven to make the passage width W 71 mm obtained by adding a margin of about 1 mm to the bill width. Thus, the position of the width guide 50 is controlled (see FIG. 12 (c)). Similarly, if the bill B is a 5 bill or 1 bill having a bill width of 63 mm, the bill transport means 30 is driven so that the passage width W is 64 mm obtained by adding a margin of about 1 mm to the bill width. Control the position of the width guide 50 (see FIG. 12 (d))). If the inserted bill B is a pentagon tag or single bracket tag having a bill width of less than 63 mm, or if the inserted paper piece is a card, the width guide 50 is controlled without driving the bill transport means 30. do not do.

(5) Here, when the inserted bill B is deformed due to wrinkles, creases, water wetting, deterioration or the like, the control device is a passage sensor 80 provided along the bill conveyance passage portion 20 (FIG. 2 and FIG. Based on the detection result according to FIG. 6), it is determined that the bill B is not a prescribed bill. For example, when the inserted bill B does not simultaneously pass through the pair of left passage sensor 80L and right passage sensor 80R at the same horizontal position, or when the bill conveying means 30 is driven for a certain time, the control device is most downstream D If either the left passage sensor 83L or the right passage sensor 83R does not detect the bill B, the bill B is inserted as if it was not conveyed in the correct posture or was not conveyed to the normal position. It is determined that the bill B is not a prescribed bill.
(6) If the control device determines that the inserted bill B is not a prescribed bill, it drives the bill transport means 30 so as to carry out the inserted bill B from the downstream D in the upstream U direction.
(7) At this time, the control device drives the electric motor 61 to raise the movable cam 70 from the normal position to the insertion port enlargement position. Then, the movable cam 70 lifts the height guide 11 from the normal position to the insertion port enlargement position. That is, the insertion port 10a changes from the normal state to the insertion port expansion state (see FIG. 11B). As a result, the insertion port 10a, which is narrowed in the normal state, is expanded, so that it becomes easy to carry out the deformed bill B.
