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 device 100, and the outer shell portion of the case 1 and the bills. The illustration of the storage unit 40 is omitted.

As shown in FIGS. 1 to 7, the banknote processing device 100 has a banknote insertion unit 10 for inserting banknotes B (not shown) in the upstream U, and a banknote storage unit 40 for stacking and storing banknotes B in the downstream D. The banknote transport passage portion 20 is provided, and the bill transport means 30 for transporting the bill B along the bill transport passage portion 20 is provided. The banknote B inserted into the banknote insertion section 10 is transported by the banknote transport means 30 from the upstream U to the downstream D along the banknote transport aisle section 20 under specific conditions, and under specific conditions, the banknote transport means. By 30, the banknotes are transported from the downstream D to the upstream U along the bill transport passage portion 20.

The banknote processing device 100 is inserted when the banknote width of the banknote B inserted from the banknote insertion unit 10 is within a preset range in an area where a plurality of types of banknotes B having different banknote widths are distributed. The banknotes B are stacked and stored in the banknote storage unit 40.
For example, the combinations of banknote types and banknote widths distributed as RMB in China are 100 yuan bills (77 mm), 50 yuan bills (70 mm), 20 yuan bills (70 mm), 10 yuan bills (70 mm), and 5 yuan bills. There are original bills (63 mm) and 1 original bills (63 mm). In addition to these, there are pentagonal bills (59 mm) and 1 square bills (52 mm), but the bill width is 77 mm, 70 mm or 63 mm depending on the bill processing device 100. Accept and store the original bills. That is, it is possible to prevent the banknotes having a width of less than 63 mm from being stored without being accepted.

Explaining the structure of the bill processing device 100, specifically, as shown in FIG. 1, the bill insertion portion 10, the bill transport passage portion 20, the bill transport means 30, and the bill storage portion 40 of the bill processing device 100 are respectively. It is supported by the case 1 and assembled integrally.

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

As shown in FIG. 4, the height dimension β of the insertion slot 10a defined by the bill insertion portion 10 stabilizes the posture of the bill B toward the bill transport passage portion 20 located downstream D of the insertion port 10a. 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 in order to guide the bills as they are.

Since the bill insertion portion 10 has a height guide 11 that can reciprocate in the vertical direction, the height guide 11 can reciprocate between the normal position and the insertion slot expansion position. The defined height dimension β of the insertion slot 10a is variable between the normal state and the insertion slot enlarged state larger than the normal state. Therefore, for example, when the banknote B that is deformed into a bellows shape and has a large height dimension is sent out, the banknote B can be made into a state in which the insertion port 10a is expanded in the height direction from the normal state. It is possible to prevent the height guide 11 from coming into contact with the height guide 11 and becoming a resistance to carry out, and as a result, to prevent clogging inside the bill transport passage portion 20, and to return the deformed bill B.

As shown in FIG. 13, the receiving guide 12 may be a part of the case 1 or may be a separate body fixed to the case 1. The receiving guide 12 has a width slightly larger than the width of the receiving bill B. In order to reduce the resistance with the bill B, a plurality of ribs 12r extending along the direction in which the bill B is inserted and curved toward the insertion port 10a are provided on the upper surface of the receiving guide 12.

As shown in FIGS. 13 and 18, the height guide 11 has a width equivalent to the largest banknote width among the banknotes B used. The width of the height guide 11 is smaller than the width of the receiving guide 12 in order to make the entire bill processing apparatus 100 compact. The height guide 11 includes a shaft support portion 11a that is pivotally supported by the case 1, a height guide engaging portion 11p that is engaged with the movable cam engaging portion 74 of the movable cam 70, and a state other than the insertion port enlarged state. It has a stopper 11s supported by the case 1. The shaft support portion 11a and the stopper 11s are provided at both ends of the height guide 11, respectively. The stopper 11s swings in the direction in which the insertion port 10a expands (the direction indicated by the arrow θ in FIG. 11B) while the height guide 11 is pivotally supported by the shaft support portion 11a. However, it is engaged with the case 1 so that it can swing only to a predetermined position in the opposite direction. Therefore, in the height guide 11, the shaft support portion 11a is pivotally supported with respect to the case 1 in a state other than the insertion port enlarged state, that is, in a state from the normal state to the passage width of 64 mm through the passage width of 71 mm. The stopper 11s is supported, and the position of the height guide 11 is maintained at the normal position.

The height guide 11 reciprocates according to the ascending / descending motion of the movable cam 70. This will be described later.

Further, the bill insertion unit 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 arranged on both sides of the insertion slot 10a in the bill insertion portion 10 so as to be arranged along the width direction. The width detection sensor may be arranged at the end of the bill transport passage portion 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 arranged on one side in the vertical direction of the insertion port 10a, the light receiving unit is arranged on the other side, and the light emitted from the light emitting unit is arranged in the insertion port 10a. It straddles the vertical direction and reaches the light receiving part. The optical sensors are arranged side by side (passage width direction) at a pitch of 1 mm, for example. As described above, the width detection sensors are not arranged in the central portion of the insertion slot 10a in the bill insertion portion 10, but are arranged together on both side portions, so that the bill widths are different even if a large number of optical sensors are not arranged. A plurality of types of banknotes B can be identified, and banknotes and the like having a width not within a preset range can be identified.

(Banknote transport passage)
The bill transport 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 section 10, the bill transport means 30, and the bill storage section 40 are provided along the bill transport passage section 20. As schematically shown in FIG. 4, the bill transport passage portion 20 includes a horizontal portion 21 extending laterally from the bill insertion portion 10, a curved portion 22 curved upward from the horizontal portion 21, and a vertical portion extending in the vertical direction. 23 and. 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.

(Banknote transport means)
The bill transporting means 30 includes, for example, a drive source (not shown) and a rubber belt (not shown) that is wound around a pulley (not shown) connected to the drive source and has a large friction with respect to the bill B. .. The bill transporting means 30 may use the drive unit 60 as a drive source. As shown in FIG. 4, the bill transporting means 30 is provided along a portion (horizontal portion 21 or curved portion 22) of the bill transport passage portion 20 excluding the portion along the bill storage portion 40 (vertical portion 23). As a result, the bill B transported from the upstream U toward the downstream D receives a vertically upward force by the bill transporting means 30, and when it reaches the vertical portion 23, the bill B is directed from the upper side of the bill B toward the upstream U. The pulling force does not act, and the bill B is supported only from the lower end portion in the passage of the bill transport passage portion 20, in other words, the bill B is standing. Therefore, if 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 length of the bill B reaches. Since 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, the bill B conveyed to the vertical portion 23 is not a specified bill. Can be detected.
Further, the bill transporting means 30 may also be provided at a portion of the bill transporting passage portion 20 along the bill storage portion 40. As a result, the banknote B transported from the upstream U to the downstream D receives a vertically upward force by the banknote transport means 30 and reaches the vertical portion 23. Then, a force that pulls the banknote B from the upper side of the banknote B toward the upstream U acts from the banknote transport means 30 provided along the portion along the banknote storage unit 40, making it difficult for the banknote B to be deformed in the compression direction, and the banknote B becomes difficult to deform. The risk of clogging in the transport passage portion 20 is reduced. Therefore, the number of passage sensors 80 for detecting the clogging of the bill B can be reduced.

(Relationship between drive unit and movable cam)
The banknote processing device 100 includes a drive unit 60 and a movable cam 70 that moves up and down in response to the movement of the drive unit 60.
Then, the height guide 11 of the bill insertion portion 10 reciprocates in the vertical direction according to the ascending / descending motion of the movable cam 70. The reciprocating motion includes an ascending / descending motion and a swing motion centered on the shaft support portion 11a. In this way, the height guide 11 reciprocates in response to the ascending / descending motion of the movable cam 70 accompanying the motion of the drive unit 60, so that the bill B is sent out from the downstream D to the upstream U by the bill transporting means 30. By controlling the drive unit 60, the height guide 11 can be moved from the normal position to the upper position in the vertical direction so that the height dimension of the insertion port 10a is larger than the normal state. Therefore, it is possible to prevent the bill B from being clogged inside the bill transport passage portion 20, and the deformed bill B can be returned.

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

The banknote processing device 100 includes pulse sensors 61s (see FIGS. 10 and 11) that generate pulses in response to changes in the rotation position (rotation angle) of the electric motor 61. Then, the control device controls the rotation position (rotation 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 rotate in conjunction with each other.

As shown in FIG. 15, the worm wheel 63 has a wheel engaging portion 63p protruding in a direction along the rotation center axis at a position eccentric from the rotation center axis. The wheel engaging portion 63p engages with the horizontally long cam engaging groove 72 provided in the movable cam 70.
As a result, when the worm wheel 63 rotates, the wheel engaging portion 63p acts on the cam engaging groove 72 to move the movable cam 70 in the vertical direction. Since the guide groove 73 of the movable cam 70 is engaged with a guide rail (not shown) provided in the case 1, the movable cam 70 is in the vertical direction in conjunction with the rotation of the worm wheel 63. Moves in parallel to and moves up and down.

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

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

Specifically, when the wheel engaging portion 63p of the worm wheel 63 is located substantially at the center of the worm wheel 63 in the vertical direction, that is, when it is located to the left or right of the rotation center of the worm wheel 63, the movable cam 70 Is the normal position (see FIG. 11 (a)), and when the wheel engaging portion 63p is located above the worm wheel 63 in the vertical direction, the movable cam 70 is in the insertion port enlarged position (see FIG. 11 (b)). When the wheel engaging portion 63p is located slightly below the worm wheel 63 in the vertical direction, the movable cam 70 is located at a passage width of 71 mm (see FIG. 11C), and the wheel engaging portion 63p is the worm wheel 63. When the movable cam 70 is located further downward in the vertical direction, the movable cam 70 is located at a passage width of 64 mm (see FIG. 11D).

In this way, 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, an external force other than that due to the drive unit 60 from the height guide 11 and the width guide 50 can move. Even if it acts on the cam 70, the movable cam 70 is difficult to move due to the unidirectional frictional resistance between the worm shaft 62 and the worm wheel 63. Therefore, the height guide 11 and the width guide 50 that are interlocked with the movable cam 70 are difficult to move. Therefore, fraudulent acts such as withdrawal of bill B can be suppressed.

The cam groove 71 of the movable cam 70 is, in detail, a continuous oblique groove 70S and a vertical groove 70L, as shown in FIGS. 12A to 12D and FIG. Specifically, the cam groove 71 has a symmetrical shape in the rear view, and has a pair of vertical grooves 70L and a pair of oblique grooves 70S on the left and right sides. The pair of oblique grooves 70S are inclined at, for example, approximately 45 degrees with respect to the vertical direction. The uppermost portions of the respective inclined grooves 70S in the pair of inclined grooves 70S may or may not be connected to each other and continuous.

The left width guide engaging portion 51p and the right width guide engaging portion 52p are engaged with the cam groove 71, and the left width guide engaging portion 51p and the right width guide engaging portion 52p approach or separate from each other. Since the movable cam 70 moves in parallel in the direction of movement, 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 as the movable cam 70 moves up and down. , The left width guide engaging portion 51p and the right width guide engaging portion 52p come close to each other and separate from each other.

As described above, since the cam groove 71 has a symmetrical shape, the left width guide engaging portion 51p and the right width guide engaging portion 52p can be moved left and right by simply moving the movable cam 70 in parallel in the vertical direction and moving it up and down. It can be moved symmetrically.

The movable cam engaging portion 74 is provided on both side ends of the movable cam 70 in front of the movable cam 70. The movable cam engaging portion 74 has a bulging portion 74a that bulges from the back surface to the front surface and a bulging portion 74a that bulges from the back surface to the front surface as shown in FIGS. A recess 74b is provided continuously with the bulge 74a at the lower part of the dent and the bulge 74a, and a recess 74b is continuously provided at the lower part of the recess 74b. It has a protruding portion 74c and a protruding portion 74c.

(Relationship between movable cam and height guide)
The height guide engaging portion 11p of the height guide 11 is a movable cam when the movable cam 70 is between the normal position (see FIG. 11A) and the insertion opening enlarged position (see FIG. 11B). It moves relative to the movable cam 70 that moves up and down while being in contact with any of the bulging portion 74a, the recess 74b, or the protruding portion 74c of the engaging portion 74.

Specifically, when the movable cam 70 is in the normal position (see FIG. 11A), the height guide engaging portion 11p is in contact with the bulging portion 74a of the movable cam 70, and the height guide 11 is inserted. 10a is the normal position where the normal height dimension is obtained. When the movable cam 70 is in the insertion port enlarged position (see FIG. 11B), that is, when the movable cam 70 moves vertically upward from the normal position, the height guide 11 moves the height guide engaging portion 11p. When the stopper 11s is no longer supported in contact with the protruding portion 74c of the cam 70 and the movable cam 70 further moves vertically upward, the height guide 11 swings around the shaft support portion 11a and the height guide engages. The insertion port enlarged position where the portion 11p swings in the rear direction and comes into contact with the recess 74b of the movable cam 70, the entire height guide 11 swings by a predetermined angle θ, and the insertion port 10a becomes 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 position (see FIG. 11D), that is, the movable cam 70 moves vertically downward from the normal position. However, since the height guide 11 is supported by the shaft support 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. 11 (a)), the passage width 71 mm position (see FIG. 11 (c)), and the passage width 64 mm position (see FIG. 11 (d)). Become a posture.

(Relationship between movable cam and width guide)
By the way, the bill transport passage portion 20 includes a pair of opposite width guides 50 provided on both side portions of the bill transport passage portion 20. The distance between the pair of width guides 50 and the passage width W of the bill transport passage portion 20 are steplessly variable according to the drive of the drive portion 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 allow the left width guide 51 to move in parallel in the lateral direction, for example, a rack 51 g is provided along the lateral direction in the left width guide 51. The right width guide 52 is provided with a rack 52 g facing the rack 51 g along the lateral direction. Two pinions (not shown) are provided between the rack 51 g and the rack 52 g, for example, in order to enable smooth relative movement with low frictional resistance while maintaining the distance between the rack 51 g and the rack 52 g. Have been placed.

Further, as shown in FIGS. 12A to 12D, the left width guide 51 is provided with a left width regulating portion 51w, and the right width guide 52 is provided with a right width regulating portion 52w. The left width regulating portion 51w and the right width regulating portion 52w define the passage width W (see FIG. 12) of the bill transport passage portion 20.
The cross sections of the left width regulating portion 51w and the right width regulating portion 52w have a uniform shape orthogonal to the transport direction. Further, the cross sections of the left width regulating portion 51w and the right width regulating portion 52w are laterally rotated 90 degrees in the letter U of the alphabet, as represented by (a) to (d) of FIG. It has a shape in which one end is open and the other end is closed, as if it were tilted down. The open portion at one end of each of the left width regulating portion 51w and the right width regulating portion 52w is substantially parallel with the inner surfaces facing in the vertical direction, and the closed portion at the other end has the inner surface in the vertical direction. It is straightened to. The left width regulating portion 51w and the right width regulating portion 52w are arranged so that the open portions at one end in each cross section face each other in the width direction (horizontal direction). The left width regulating section 51w and the right width regulating section 52w are part of the bill transport passage section 20, and the bill B is guided by the inner surface of the left width regulating section 51w and the inner surface of the right width regulating section 52w. Is to maintain. The dimension from the left end on the inner surface of the left width regulating portion 51w to the right end on the inner surface of the right width regulating portion 52w is the passage width W.

The pair of width guides 50 each have a left width guide engaging portion 51p and a right width guide engaging portion 52p that are engaged with the cam groove 71 of the movable cam 70. Specifically, the left width guide 51 and the right width guide 52 have a left width guide engaging portion 51p and a right width guide engaging portion 52p that are engaged with the cam groove 71 of the movable cam 70, respectively. The left width guide engaging portion 51p and the right width guide engaging portion 52p are, for example, columnar protrusions as shown in FIGS. 13, 16 and 17.

Then, the left width guide 51 and the right width guide 52 are engaged with the movable cam 70. Therefore, when the movable cam 70 moves in parallel in the vertical direction, the left width guide 51 and the right width guide 52 move in parallel in the direction of approaching or moving away from each other.
As described above, the pair of width guides 50 and height guides 11 are moved by a common movable cam 70 that moves up and down by the drive unit 60. In this way, a pair of width guides 50 and height guides, which are two functional parts having different movement directions, are generated by one-way movement by the movable cam 70, which is a single component corresponding to the movement of the single drive unit 60. Since both of the eleven can be moved, the motion transmission mechanism from the drive unit 60 to each functional unit can be simplified, and the entire device can be made compact.

(Aisle sensor)
As shown in FIGS. 2 and 6, the passage sensor 80 is provided along the bill transport passage portion 20. The passage sensor 80 has a plurality of a pair of left passage sensors 80L and right passage sensors 80R in the same horizontal position (horizontal position) arranged side by side from the upstream U to the downstream D.

Specifically, the passage sensor 80 has a left passage sensor 81L or a right passage sensor 81R, a left passage sensor 82L or a right passage sensor 82R, and a left passage sensor 83L or a right passage sensor 83R in order from the upstream U. The left passage sensor 83L or the right passage sensor 83R located at the most downstream D is provided at a position separated by a specified length of the bill B from the bill transport means 30 in the vertical portion 23 of the bill transport passage portion 20. Although the passage sensor 80 is provided in the vertical portion 23 in the present embodiment, it may be provided in the horizontal portion 21 or the curved portion 22.

As a result, the control device does not pass through the pair of left passage sensors 80L and right passage sensors 80R at the same horizontal position at the same time, or even if the banknote transport means 30 is driven for a certain period of time, the left passage sensor located at the most downstream D If either the 83L or the right passage sensor 83R does not detect the bill B, it can be determined that the bill B has not been transported in the correct posture or the bill B is deformed and is not a specified bill. In particular, when a plurality of pairs of left passage sensors 80L and right passage sensors 80R are provided along the bill transport passage portion 20, the control device detects by all the plurality of pairs of left passage sensors 80L and right passage sensors 80R. It can be judged using the result. In this case, the control device can detect the clogging of the bill B at an early stage when the bill B is on the upstream U side, and can accelerate the timing of discharging the non-standard bill B.

(Action)
Next, the operation of the banknote processing device 100 when the banknote B is inserted into the banknote insertion unit 10 will be described. Here, a case where the banknote width is set in the range of 63 mm to 77 mm will be described on the assumption that the banknote is used in an area where the Chinese yuan is distributed.
(1) First, the initial state of the bill processing apparatus 100 is a normal state, the passage width W is the largest state (see FIG. 12A), and the insertion slot 10a is a narrow state (FIG. 11 (a)). )).
When the bill B is inserted into the insertion slot 10a, a part of the plurality of optical paths by the plurality of optical sensors in which the bill B is arranged is blocked, and some optical sensors detect that the optical path is blocked. do.
(2) The control device (not shown) calculates the bill width or the parameter corresponding to the bill width of the bill B based on the number and arrangement of the detected optical sensors.
(3) The control device raises and lowers the movable cam 70 by controlling the rotation position (rotation angle) of the electric motor 61 of the drive unit 60 based on the calculated bill width of the bill B, and a pair of width guides. The distance between the 50s, that is, the passage width W of the bill transport passage portion 20 is adjusted.
(4) At this time, if the banknote width of the banknote B is within a preset range as a result of the calculation of the banknote width of the banknote B or the parameter corresponding to the banknote width, the control device uses the banknote transport means 30. The banknote B is driven and transported along the banknote transport passage portion 20, and as a result of the calculation, the banknote transport means 30 is not driven unless the banknote width of the banknote B is within the preset range.
Since the banknote width of the banknote B is set in the range of 63 mm to 77 mm in advance, the control device drives the banknote transport means 30 and passes through if the banknote B is a 100 yuan bill having a banknote width of 77 mm. The position of the width guide 50 is maintained in the initial state (normal state) so that the width W is 78 mm, which is obtained by adding a margin of about 1 mm to the width of the bill (see FIG. 12 (a)). If the bill B is a 50 yuan bill, a 20 yuan bill, or a 10 yuan bill having a bill width of 70 mm, the bill transporting means 30 is driven, and the passage width W is 71 mm, which is the bill width plus a margin of about 1 mm. As described above, the position of the width guide 50 is controlled (see FIG. 12 (c)). Similarly, if the bill B is a 5-yuan bill or a 1-yuan bill having a bill width of 63 mm, the bill transporting means 30 is driven so that the passage width W becomes 64 mm, which is the width of the bill plus a margin of about 1 mm. In addition, the position of the width guide 50 is controlled (see FIG. 12 (d)). If the inserted bill B is a pentagonal bill or a single-square bill having a bill width of less than 63 mm, or if the inserted paper piece is a card, the bill transporting means 30 is not driven and the width guide 50 is controlled. do not.
In this way, since the passage width W is adjusted according to the bill width of the inserted bill B, the bill processing device 100 conveys the bill B along the bill transport passage portion 20 when the bill B is transported along the bill transport passage portion 20. The banknotes can be transported to the downstream D of the banknote transport passage 20 and stored in the banknote storage section 40 while being maintained in the correct posture without being tilted obliquely with respect to the transport direction in the section 20.
(5) Here, when the inserted banknote B is deformed due to wrinkles, creases, water wetting, deterioration, etc., the control device is a passage sensor 80 provided along the banknote transport passage portion 20 (FIG. 2 and FIG. Based on the detection result (see FIG. 6), it is determined that the banknote B is not a specified banknote. For example, in the control device, even if the inserted banknote B does not pass through the pair of left passage sensors 80L and the right passage sensor 80R at the same horizontal position at the same time, or even if the banknote transport means 30 is driven for a certain period of time, the most downstream D If either the left passage sensor 83L or the right passage sensor 83R in the above 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 the specified bill.
(6) When the control device determines that the inserted banknote B is not a specified banknote, the control device drives the banknote transport means 30 so as to carry out the inserted banknote 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 expansion position. Then, the movable cam 70 lifts the height guide 11 from the normal position to the insertion port enlarged position. That is, the insertion port 10a changes from the normal state to the insertion port enlarged state (see FIG. 11B). As a result, the insertion slot 10a, which is narrow in the normal state, is enlarged, so that the deformed bill B can be easily carried out.

Although the preferred embodiment of the present invention has been described in detail above, the bill processing apparatus 100 according to the present invention is not limited to the above-described embodiment, but is within the scope of the gist of the present invention described in the claims.

The banknote transport passage portion 20 is provided, and the bill transport means 30 for transporting the bill B along the bill transport passage portion 20 is provided. Since it has a flexible height guide 11, it is easy to return the deformed bill B.

According to the bill processing apparatus 100 of the present invention, the bill transport passage portion 20 includes a pair of width guides 50 facing each other provided on both sides of the bill transport passage portion 20, and the distance between the pair of width guides 50 is driven. Since it is steplessly variable according to the movement of the unit 60, if the banknote width of the banknote B used is within a predetermined range, a pair of width guides 50 are finely tuned according to the banknote width that differs depending on the type of the banknote B. The distance between the bills can be adjusted, and the inserted bill B can be transported in the correct posture.

According to the bill processing device 100 of the present invention, the movable cam 70 that moves up and down according to the movement of the drive unit 60 is provided, and the height guide 11 reciprocates in the vertical direction according to the movement of the movable cam 70. The height guide 11 can make a motion similar to the motion of the movable cam 70 converted from the motion of the drive unit 60, that is, the motion of the drive unit 60, that is, the rotation position (rotation angle) of the electric motor 61. The movement of the height guide 11 can be easily controlled only by controlling it.

According to the bill processing apparatus 100 of the present invention, the movable cam 70 has at least a cam groove 71 in which the oblique groove 70S and the vertical groove 70L are continuously provided, and a movable cam engaging portion 74, and a pair. The width guide 50 has a left width guide engaging portion 51p and a right width guide engaging portion 52p that are engaged with the cam groove 71, respectively, and the height guide 11 engages with the movable cam engaging portion 74. Since the height guide engaging portion 11p is provided, the height guide 11 can be reciprocated in the vertical direction and the width guide 50 can be moved in the lateral direction simply by moving the movable cam 70 in parallel and moving it up and down. .. That is, the height guide 11 and the width guide 50 share the movable cam 70, and the movement of the height guide 11 and the movement of the width guide 50 can be combined with the movement of a single movable cam 70.

According to the bill processing device 100 of the present invention, since the cam groove 71 has a symmetrical shape, the left width guide 51 and the right width guide 52 can be moved symmetrically only by raising and lowering the movable cam 70. ..

According to the bill processing device 100 of the present invention, the drive unit 60 includes an electric motor 61 having an output shaft 61a, a worm shaft 62 interlocking with the rotation of the output shaft 61a, and a worm wheel 63 interlocking with the rotation of the worm shaft 62. Since the movable cam 70 moves up and down in conjunction with the rotation of the worm wheel 63, the drive unit 60 is combined with a spur gear due to the unidirectional frictional resistance between the worm shaft 62 and the worm wheel 63. The movable cam 70 is more difficult to move than the one configured by the above. Therefore, the height guide 11 and the width guide 50 are difficult to move. Therefore, fraudulent acts such as withdrawal of bill B can be suppressed.

According to the bill processing device 100 of the present invention, the pair of width guides 50 and the height guides 11 are moved by a common movable cam 70 that moves up and down by the drive unit 60, so that the pair of width guides 50 and the height guides 11 respond to the movement of the single drive unit 60. By moving in one direction by the movable cam 70, which is a single component, both the pair of width guides 50 and the height guides 11, which are two functional parts having different movement directions, can be moved from the drive unit 60. The motion transmission mechanism to each functional part can be simplified, and the entire device can be made compact.
