The pressed rollers 72d and 76d (see FIG. 7) are rotatably attached to the side, and these pressed rollers 72d and 76d are selectively selected by a first cam 82 and a third cam 86 of the cam mechanism 80 described later. It comes to be pressed.

  The cam mechanism 80 changes the types of driven rollers 62, 64, and 66 that are pressed by the driving rollers 52, 54, and 56. Specifically, the cam mechanism 80 presses one type of driven roller among the first driven roller 62, the second driven roller 64, and the third driven roller 66 toward the drive roller and another type of driven roller. The driven roller is separated upward from the driving roller. More specifically, the cam mechanism 80 includes a first cam 82, a second cam 84, and a third cam that are provided to face the pressed rollers 72d, 74d, and 76d of the driven roller support portions 72, 74, and 76, respectively. 86. Here, in the cam mechanism 80, two first cams 82, two second cams 84, and two third cams 86 are arranged along the width direction of the bill conveyance path in the bill shift device 50. A plurality of sets (specifically, four sets in the examples shown in FIGS. 2 to 4) are provided so that the combination of the first cam 82, the second cam 84, and the third cam 86 is aligned in the bill conveyance direction. Yes. Further, as shown in FIG. 5, when the banknote shift device 50 shown in FIG. 2 is viewed from the front side, the second cam 84, the first cam 82, the third cam 86, the second cam 84, the first, A cam 82 and a third cam 86 are arranged. In each combination of the first cam 82, the second cam 84, and the third cam 86, each cam 82, 84, 86 has one cam shaft 88 (see FIGS. 4 and 5, see FIGS. 2 and 3). (Not shown) is rotatably supported. The cam mechanism 80 is provided with a drive motor (not shown) such as a stepping motor that rotates the cam shaft 88 in both forward and reverse directions. The drive motor rotates the cam shaft 88 in both forward and reverse directions. It has become. Further, a plurality of cam mechanisms 80 (four in the example shown in FIGS. 2 to 4) are provided so as to be aligned along the bill conveyance direction, and the cam shaft 88 of each cam mechanism 80 is a cam of another cam mechanism 80. It rotates independently of the shaft 88. In addition, the banknote shift apparatus 50 of this Embodiment is not limited to such an aspect. In the bill shift device 50 according to the modification, the cam shafts 88 of the cam mechanisms 80 may be rotated in synchronization by being connected to each other by a connecting portion such as a gear (not shown). In this case, the cam shaft 88 of each combination is rotated synchronously by one drive motor, so that all the cams 82, 84, 86 shown in FIG. 2 are rotated synchronously. In the following description, a mode in which the cam shaft 88 of each cam mechanism 80 rotates independently from the cam shaft 88 of the other cam mechanism 80 will be described.

  Further, in the present embodiment, each of the cams 82, 84, 86 has a generally disk shape, and concave portions 82a, 84a, 86a are formed in part of the outer peripheral edge thereof. Here, as shown in FIG. 6, the phase of the concave portion 84 a formed on the outer peripheral edge of the second cam 84 is different from the phase of the concave portion 82 a formed on the outer peripheral edge of the first cam 82. That is, in the clockwise direction of FIG. 6, the phase of the concave portion 84 a formed on the outer peripheral edge of the second cam 84 is positioned downstream of the phase of the concave portion 82 a formed on the outer peripheral edge of the first cam 82. ing. The phase of the recess 86 a formed on the outer peripheral edge of the third cam 86 is the phase of the recess 82 a formed on the outer peripheral edge of the first cam 82 and the phase of the recess 84 a formed on the outer peripheral edge of the second cam 84. Is different. That is, in the clockwise direction of FIG. 6, the phase of the recess 86 a formed on the outer peripheral edge of the third cam 86 is positioned upstream of the phase of the recess 82 a formed on the outer peripheral edge of the first cam 82. ing. As a result, the driven roller support portion provided corresponding to the cam only in the concave portion of one of the three types of cams 82, 84, 86 depending on the rotational phase of the cam shaft 88. The roller comes in, and the driven roller supported by the driven roller support portion is pressed against the driving roller. On the other hand, since the pressed roller of the driven roller support portion provided corresponding to the other type of cam does not enter the concave portion of the cam, the pressed roller is pressed downward by the cam. The driven roller supported by the support part is separated upward from the driving roller. In this way, depending on the rotational phase of the cam shaft 88, any one of the first driven roller 62, the second driven roller 64, and the third driven roller 66 is pressed toward the drive roller and the others. This type of driven roller is spaced upward from the drive roller.

  In the present embodiment, as shown in FIG. 7A, the cam shaft 88 is such that the pressed roller 72d of the first driven roller support portion 72 enters the recess 82a of the first cam 82 in a normal state. The rotation phase is maintained. In this case, the first driven roller 62 is pressed against the first drive roller 52 and the second driven roller 64 and the third driven roller 66 are separated upward from the second drive roller 54 and the third drive roller 56. become. On the other hand, when the cam shaft 88 is rotated in the clockwise direction in FIG. 7 by a drive motor such as a stepping motor (not shown), the cam shaft 88 is in the recess 86a of the third cam 86 as shown in FIG. The rotation phase is such that the pressed roller 76d of the third driven roller support portion 76 enters. In this case, the third driven roller 66 is pressed by the third drive roller 56, and the first driven roller 62 and the second driven roller 64 are separated upward from the first drive roller 52 and the second drive roller 54. become. When the cam shaft 88 is rotated in the counterclockwise direction in FIG. 7 by a drive motor such as a stepping motor (not shown), the cam shaft 88 is recessed in the second cam 84 as shown in FIG. The rotation phase is such that the pressed roller 74d of the second driven roller support portion 74 enters 84a. In this case, the second driven roller 64 is pressed by the second drive roller 54, and the first driven roller 62 and the third driven roller 66 are separated upward from the first drive roller 52 and the third drive roller 56. become.

  Further, as shown in FIG. 3, in the banknote shift device 50, a first detection sensor such as a line sensor is located upstream of the drive rollers 52, 54, 56 and the driven rollers 62, 64, 66 in the banknote transport direction. 90 is provided. The position in the width direction of the banknote before being sent to each drive roller 52, 54, 56 and each driven roller 62, 64, 66 by the first detection sensor 90 (that is, before being shifted in the width direction) is determined. It is to be detected. Further, in the bill shift device 50, a second detection sensor 92 such as a line sensor is provided on the downstream side of the drive rollers 52, 54, 56 and the driven rollers 62, 64, 66 in the bill conveyance direction. Such a second detection sensor 92 detects the position in the width direction of the banknotes discharged from the drive rollers 52, 54, 56 and the driven rollers 62, 64, 66 (that is, after being shifted in the width direction). It has come to be.

  Next, the operation of the bill shift device 50 having such a configuration (specifically, the operation of selectively shifting the bill in the width direction by the bill shift device 50) will be described.

  The banknote sent from the transport unit 16 to the banknote shift device 50 is first detected in the width direction by the first detection sensor 90. Then, based on the position in the width direction of the banknote detected by the first detection sensor 90, the banknote shift device 50 calculates the direction and amount (shift amount) for shifting the banknote in the width direction. Specifically, when the banknote shift device 50 shifts the banknote to, for example, the center position in the width direction of the transport path, the position in the width direction of the banknote detected by the first detection sensor 90 and the width direction of the transport path. The distance between the center position of the banknote is an amount by which the banknote shift device 50 shifts the banknote in the width direction. In addition, when the position in the width direction of the banknote conveyed by the conveyance part 16 can be detected by the identification part 18, it is not the position in the width direction of the banknote detected by the first detection sensor 90, but the identification part 18 Based on the position in the width direction of the banknote detected by, the direction and amount of shifting the banknote in the width direction by the banknote shift device 50 may be calculated.

  When it is determined by the bill shift device 50 that it is not necessary to shift the bill in the width direction based on the position in the width direction of the bill detected by the first detection sensor 90 or the identification unit 18, The cam shaft 88 is maintained in the rotation phase as shown in FIG. 7A without being rotated by a drive motor such as a stepping motor. As described above, in the normal state, as shown in FIG. 7A, the cam shaft 88 is in a rotational phase such that the pressed roller 72 d of the first driven roller support portion 72 enters the recess 82 a of the first cam 82. To be maintained. In this case, the arm portion of the first driven roller support portion 72 is biased counterclockwise in FIG. 7 about the support shaft by the torsion spring, whereby the first driven roller 62 is moved to the first drive roller 52. Will be pressed. On the other hand, the recessed rollers 84a and 86a of the second cam 84 and the third cam 86 do not enter the pressed rollers 74d and 76d of the second driven roller support portion 74 and the third driven roller support portion 76. The rollers 74 d and 76 d are in contact with the outer peripheral edges of the second cam 84 and the third cam 86. In this case, in the second driven roller support portion 74 and the third driven roller support portion 76, the arm portion is urged in the clockwise direction in FIG. 7 around the support shaft against the urging force of the torsion spring. As a result, the second driven roller 64 and the third driven roller 66 are separated from the second drive roller 54 and the third drive roller 56. Moreover, since the 1st driven roller 62 faces the conveyance direction (namely, left direction in FIG. 3) of the banknote in the banknote shift apparatus 50, in the banknote shift apparatus 50, it is the 1st drive roller 52 and the 1st driven. The bills conveyed between the rollers 62 are not shifted in the width direction.

  Moreover, when it is judged that it is necessary to shift the banknote to the right side in the width direction by the banknote shift device 50 based on the position in the width direction of the banknote detected by the first detection sensor 90 or the identification unit 18. In the cam mechanism 80, the cam shaft 88 is rotated in the counterclockwise direction in FIG. 7 by a drive motor such as a stepping motor. Specifically, the amount of shift (shift amount) in the width direction by the banknote shift device 50 calculated based on the position in the width direction of the banknote detected by the first detection sensor 90 is shown in FIG. The number of cam shafts 88 of the cam mechanism 80 that is rotated in the clockwise direction is determined. As shown in FIG. 7C, the cam shaft 88 rotated in the counterclockwise direction in FIG. 7 by the drive motor is moved to the recessed portion 84a of the second cam 84 by the second driven roller support portion 74. The rotation phase is such that the pressing roller 74d enters. In this case, the arm portion of the second driven roller support portion 74 is biased counterclockwise in FIG. 7 by the torsion spring around the support shaft, whereby the second driven roller 64 is moved to the second drive roller 54. Will be pressed. On the other hand, the depressed rollers 82a and 86a of the first cam 82 and the third cam 86 do not enter the pressed rollers 72d and 76d of the first driven roller support portion 72 and the third driven roller support portion 76. The rollers 72d and 76d come into contact with the outer peripheral edges of the first cam 82 and the third cam 86. In this case, in the first driven roller support portion 72 and the third driven roller support portion 76, the arm portion is urged in the clockwise direction in FIG. 7 about the support shaft against the urging force by the torsion spring. As a result, the first driven roller 62 and the third driven roller 66 are separated from the first drive roller 52 and the third drive roller 56. Moreover, since the 2nd driven roller 64 has faced the direction which makes a predetermined angle on the right side with respect to the conveyance direction of the banknote in the banknote shift apparatus 50, in the banknote shift apparatus 50, the 2nd drive roller 54 and the 2nd driven roller The bills conveyed to 64 shift to the right side in the width direction.

  In the bill shift device 50 according to the modification in which the cam shafts 88 of the cam mechanisms 80 are connected to each other by a connecting portion such as a gear (not shown), the bill shift device 50 is rotated. After the bill has passed through the second driven rollers 64 corresponding to the number of cam shafts 88 determined by the amount (shift amount) by which the bill is shifted in the width direction, each cam shaft 88 is illustrated by a drive motor such as a stepping motor. 7 is rotated in the clockwise direction to return to the rotational phase as shown in FIG. In this case, since the pressed roller 72d of the first driven roller support 72 enters the recess 82a of the first cam 82, only the first driven roller 62 is pressed by the first drive roller 52. Therefore, the banknote is no longer shifted in the width direction.

  Moreover, when it is judged by the banknote shift apparatus 50 that it is necessary to shift a banknote to the left side in the width direction based on the position in the width direction of the banknote detected by the 1st detection sensor 90 or the identification part 18, In the cam mechanism 80, the cam shaft 88 is rotated in the clockwise direction in FIG. 7 by a drive motor such as a stepping motor. Specifically, the timepiece in FIG. 7 is determined by the amount (shift amount) of the bill shifted by the bill shift device 50 calculated based on the position in the width direction of the bill detected by the first detection sensor 90. The number of cam shafts 88 of the cam mechanism 80 that is rotated in the rotating direction is determined. As shown in FIG. 7B, the cam shaft 88 rotated in the clockwise direction in FIG. 7 by the drive motor is pressed by the third driven roller support portion 76 in the recess 86a of the third cam 86. The rotation phase is such that the roller 76d enters. In this case, in the third driven roller support portion 76, the arm portion is biased in the counterclockwise direction in FIG. Will be pressed. On the other hand, the depressions 82a and 84a of the first cam 82 and the second cam 84 do not enter the pressed rollers 72d and 74d of the first driven roller support portion 72 and the second driven roller support portion 74. The rollers 72d and 74d come into contact with the outer peripheral edges of the first cam 82 and the second cam 84. In this case, in the first driven roller support portion 72 and the second driven roller support portion 74, the arm portion is urged in the clockwise direction in FIG. 7 around the support shaft against the urging force of the torsion spring. As a result, the first driven roller 62 and the second driven roller 64 are separated from the first drive roller 52 and the second drive roller 54. Moreover, since the 3rd driven roller 66 has faced the direction which makes a predetermined angle on the left side with respect to the conveyance direction of the banknote in the banknote shift apparatus 50, in the banknote shift apparatus 50, the 3rd drive roller 56 and the 3rd driven roller The bills conveyed to 66 shift to the left in the width direction.

  In the bill shift device 50 according to the modification in which the cam shafts 88 of the cam mechanisms 80 are connected to each other by a connecting portion such as a gear (not shown), the bill shift device 50 is rotated. After the bills pass through the third driven rollers 66 corresponding to the number of cam shafts 88 determined by the amount of shift of the bills in the width direction (shift amount), each cam shaft 88 is driven by a drive motor such as a stepping motor. 7 is rotated in the counterclockwise direction to return to the rotational phase as shown in FIG. In this case, since the pressed roller 72d of the first driven roller support 72 enters the recess 82a of the first cam 82, only the first driven roller 62 is pressed by the first drive roller 52. Therefore, the banknote is no longer shifted in the width direction.

  The banknotes discharged from between the drive rollers 52, 54, 56 and the driven rollers 62, 64, 66 in the banknote shift device 50 are detected by the second detection sensor 92 in the width direction. Then, based on the position in the width direction of the banknote detected by the first detection sensor 90 and the second detection sensor 92 (or the identification unit 18 and the second detection sensor 92), the banknote shift device 50 shifts the banknote to a desired level. It is determined whether or not it has been shifted in the width direction by the amount.

  According to the banknote shift device 50 of the present embodiment configured as described above, the second drive roller 54 and the third drive roller 56 are oriented in the banknote transport direction, while the second driven roller 64 and the third drive roller 56 are oriented. The driven roller 66 is oriented in a direction that forms a predetermined angle with respect to the bill conveyance direction, and the friction coefficient of the outer peripheral surface of the second driven roller 64 and the third driven roller 66 is the second drive roller 54 and the third drive roller 66. The friction coefficient of the outer peripheral surface of the drive roller 56 is larger. In this case, the bills to be conveyed can be shifted in the width direction of the conveyance path with a simple configuration at low cost and at high speed.

  More specifically, conventionally, as a banknote shift device that adjusts the position of the banknote in the width direction of the transport path to a predetermined position, the drive roller is oriented in a direction that forms a predetermined angle on the right side with respect to the banknote transport direction. And a driven roller, and a drive roller and a driven roller that are each directed in a direction that forms a predetermined angle on the left side with respect to the banknote transport direction are known. Here, in the conventional banknote shift device, each driven roller is selectively pressed by the corresponding driving roller. And when shifting the banknote conveyed in the width direction of a conveyance path, either driven roller is pressed by the corresponding drive roller, and a banknote is conveyed between these drive rollers and a driven roller. By doing so, the position of the banknote in the width direction of the transport path can be changed. However, in such a conventional banknote shift device, a drive roller that faces in a direction that forms a predetermined angle on the right side with respect to the banknote transport direction and a direction that forms a predetermined angle on the left side with respect to the banknote transport direction. Each drive roller is provided with a facing drive roller, so that each drive roller is provided with a drive source, or when a plurality of drive rollers are driven by one drive source, the drive shaft of each drive roller is a gear or the like. There is a problem that the structure of the apparatus becomes complicated because it is necessary to connect them. On the other hand, in the banknote shift apparatus 50 of this Embodiment, since the 2nd drive roller 54 and the 3rd drive roller 56 are suitable for the conveyance direction of a banknote, these 2nd drive roller 54 and the 3rd drive roller 56 Can be driven by a single drive shaft 58, so that the above-mentioned problems of the conventional banknote shift device can be solved.

  Further, in other conventional bill shift devices, the angle of the direction of the drive shaft supporting the drive roller and the direction of the shaft supporting the driven roller with respect to the width direction of the transport path can be changed. Yes. And when shifting the banknote to be conveyed in the width direction, the direction of the driving roller and the direction of the driven roller make a predetermined angle with respect to the conveyance direction of the banknote, respectively. By transporting banknotes between them, the position in the width direction of the transported banknotes can be changed. However, in such other conventional bill shift devices, a stepping motor, a pulley, a belt, a one-way clutch, and the like are required to swing the drive shaft that supports the drive roller with respect to the width direction of the conveyance path. There is a problem that the structure of the apparatus becomes complicated. On the other hand, in the banknote shift apparatus 50 of this Embodiment, since the 2nd drive roller 54 and the 3rd drive roller 56 are suitable for the conveyance direction of a banknote, these 2nd drive roller 54 and the 3rd drive roller 56 The direction of the drive shaft 58 for driving the can be fixed, so that the above-mentioned problems of the other types of bill shift devices of the related art can be solved.

  Moreover, according to the banknote shift apparatus 50 of this Embodiment, the some driven roller 62, 64, 66 from which the angle of the direction with respect to a conveyance direction mutually differs is provided corresponding to each drive roller 52, 54, 56. The driven rollers 62, 64, and 66 are selectively pressed by the driving rollers 52, 54, and 56, respectively. Each driven roller 62, 64, 66 is configured to convey bills between the driven rollers 52, 54, 56 when pressed by the drive rollers 52, 54, 56. A cam mechanism 80 is provided corresponding to each driven roller 62, 64, 66, and the driven roller 62, pressed against the driving rollers 52, 54, 56 by the rotational phase of the cam shaft 88 of the cam mechanism 80, 64 and 66 types can be changed. As described above, the cam mechanism 80 provided corresponding to each driven roller 62, 64, 66 has the driven rollers 62, 64, 66 pressed against the drive rollers 52, 54, 56 by the rotational phase of the cam shaft 88. Since the types are changed, it is possible to shift the banknotes to be transported in the width direction of the transport path with a simple configuration at low cost and at high speed.

  More specifically, in the conventional banknote shift device, each driven roller is driven by a solenoid or the like on each driven roller support that supports each driven roller so that each driven roller is selectively pressed by the corresponding drive roller. Department was established. However, in this case, there is a problem that the structure of the bill shift device becomes complicated. On the other hand, in the banknote shift device 50 according to the present embodiment, the types of the driven rollers 62, 64, and 66 that are pressed against the driving rollers 52, 54, and 56 can be changed by the rotational phase of the cam shaft 88. The configuration of the shift device 50 can be simplified.

  Moreover, in the banknote shift apparatus 50 of this Embodiment, as mentioned above, the driven roller support parts 72, 74, and 76 that rotatably support the driven rollers 62, 64, and 66 are provided. The roller support portions 72, 74, and 76 are rotatable about a support shaft and the support shaft, and an arm portion that rotatably supports the driven rollers 62, 64, and 66, and the driven rollers 62, 64, and 66 are driven. A torsion spring as a biasing member that biases the arm portion in a predetermined rotational direction so as to be pressed by the rollers 52, 54, and 56, and a pressed portion that is provided on the arm portion and is selectively pressed by the cam mechanism 80 As the pressed rollers 72d, 74d, and 76d are pressed by the cam mechanism 80, the arm portion has a predetermined rotation direction. Driven roller 62, 64, 66 is adapted to be separated from the driving roller 52, 54, 56 by rotating in the direction. In this case, the types of driven rollers 62, 64, and 66 that are pressed against the driving rollers 52, 54, and 56 can be changed with a simple configuration. In this case, in the cam mechanism 80, cams 82, 84, 86 are attached to the cam shaft 88 corresponding to the driven rollers 62, 64, 66, and the cams 82, 84, 86 is configured to selectively press the pressed rollers 72d, 74d, and 76d of the driven roller support portions 72, 74, and 76.

  Moreover, in the banknote shift apparatus 50 of this Embodiment, as above-mentioned, several driven roller 62,64,66 is with respect to the 1st driven roller 62 and the banknote conveyance direction which are suitable for the banknote conveyance direction. The second driven roller 64 is directed to a direction that forms a predetermined angle on the right side, and the third driven roller 66 is directed to the direction that forms a predetermined angle on the left side with respect to the bill transport direction. In this case, it is selected whether the bill is shifted along the width direction of the transport path by the bill shift device 50, and whether the bill is shifted to the right side or the left side in the width direction when the bill is shifted. Will be able to. Moreover, in the banknote shift apparatus 50 of this Embodiment, the cam mechanism 80 rotates the cam shaft 88 from the rotation phase shown to Fig.7 (a), and shows the rotation phase shown in FIG.7 (b), or FIG.7 (c). With the rotational phase shown in FIG. 4, the driven roller pressed by the driving roller is selectively switched from the first driven roller 62 to the second driven roller 64 or the third driven roller 66. In this case, the first driven roller 62 is pressed against the first drive roller 52 when the rotational phase of the cam shaft 88 of the cam mechanism 80 is at a predetermined fixed position as shown in FIG. Thus, when the cam shaft 88 rotates in the forward direction or the reverse direction from the state where the rotational phase is at the fixed position, the second driven roller 64 or the third driven roller 66 becomes the second drive roller 54 or the third drive roller 56. Will be pressed. Moreover, in the banknote shift apparatus 50 of this Embodiment, as mentioned above, the cam mechanism 80 is the 2nd driven roller 64 or 3rd at the timing when the 1st driven roller 62 is spaced apart from the 1st drive roller 52. The types of driven rollers 62, 64, 66 pressed by the driving rollers 52, 54, 56 are changed so that the driven roller 66 is pressed by the second driving roller 54 or the third driving roller 56.

  Moreover, in the banknote shift apparatus 50 of this Embodiment, as above-mentioned, the 1st driven roller 62, the 2nd driven roller 64, and the 3rd driven roller 66 are arrange | positioned so that it may line up along the width direction of a conveyance path.

Compared to the case where the paper money is shifted in the width direction while being sandwiched between 54 (or one third driving roller 56), the bill can be stably shifted in the width direction. Further, in the bill shift device 50 according to the modified example in which the cam shafts 88 of the respective cam mechanisms 80 are connected to each other by a connecting portion such as a gear (not shown), the cam mechanism 80 includes: The driving rollers 52, 54, 56 are driven so that the plurality of driven rollers 62, 64, 66 provided at different positions in the conveying direction are simultaneously pressed by the corresponding driving rollers 52, 54, 56 in the conveying direction. The type of the driven rollers 62, 64, and 66 pressed by 56 can be changed.

  Moreover, in the banknote shift apparatus 50 of this Embodiment, as above-mentioned, the driven rollers 62, 64, 66 with the same direction with respect to a conveyance direction have multiple (specifically, two in the width direction of a conveyance path). ) Is provided.
