Description of the Related Art In a banknote depositing / dispensing machine that performs banknote depositing / withdrawing processing such as ATM installed in a financial institution such as a bank, a transport unit that transports banknotes is installed in the body. Banknotes transported by such a transport unit are stored in the storage cassette, but the width of the transport path of the banknotes in the transport unit is larger than the width of the opening of the storage cassette For this, it is necessary to bring the banknotes to be transported in the transport section to a predetermined position such as the center position in the width direction of the transport path. More specifically, there are a plurality of types of banknotes, and the sizes of banknotes differ depending on the issuing country and denomination. For this reason, when processing various types of banknotes, if an attempt is made to store banknotes in a storage cassette suitable for each type, the size of the opening of the storage cassette also varies depending on the type of banknote. In order to ensure that the bills enter the various storage cassettes, it is necessary to adjust the position of the bills in the width direction of the transport path to a predetermined position.

  As a device for adjusting the position of the banknote in the width direction of the transport path, Patent Document 1 discloses a banknote displacement apparatus including a skew roller that is skewed with respect to the direction in which the transport path extends. In such a bill displacement device, the bill is shifted in the width direction of the transport path when the bill is transported by the skew roller. Patent Document 2 discloses an attitude correction device including a roller whose angle with respect to a direction in which a conveyance path extends can be adjusted. In such a posture correction apparatus, when a banknote is conveyed by the roller in a state where the roller is skewed with respect to the extending direction of the conveyance path, the banknote is shifted in the width direction of the conveyance path.

  Patent Document 3 discloses a paper sheet transport apparatus in which a slide-type transport mechanism that is a combination of a roller and a guide member is slidable along the width direction of the transport path. In such a paper sheet transport apparatus, when the paper sheet is transported by the roller of the slide transport mechanism, the slide transport mechanism itself slides along the width direction of the transport path so that the paper sheet is transported. Can be shifted in the width direction.

  Next, details of the configuration of the first paper sheet shifting mechanism 20 will be described with reference to FIGS. 1 to 3. The first paper sheet shifting mechanism 20 shifts the paper sheet conveyed in a state sandwiched between the pair of upper and lower circulation belts 12 and 13 of the paper sheet conveying mechanism 10 in the width direction of the conveying path 2. ing. More specifically, as shown in FIGS. 1 and 2, the first paper sheet shift mechanism 20 is skewed in a direction skewed with respect to the direction in which the transport path 2 extends (that is, the vertical direction in FIG. 1). When the paper sheets conveyed between the pair of upper and lower circulation belts 12 and 13 come into contact with the skew rollers 22 and 24, the paper sheets are conveyed along the conveying path 2. It can be shifted in the width direction. Here, as shown in FIG. 1, the first skew roller 22 and the second skew roller 24 among the plurality of skew rollers 22 and 24 are different from each other in the skew direction with respect to the extending direction of the conveyance path 2. ing. Further, as shown in FIG. 1, a pair of left and right first skew rollers 22 are provided so as to be arranged along the width direction of the conveyance path 2, and a pair of left and right second lines are arranged along the width direction of the conveyance path 2. A skew roller 24 is provided, and each second skew roller 24 is provided downstream of each first skew roller 22 in the transport direction of the paper sheet in the transport path 2.

In the present embodiment, each first skew roller 22 and each second skew roller 24 can be positioned at the retracted position in the first paper sheet shift mechanism 20, and in this case In this case, the paper sheet transported by the paper sheet transport mechanism 10 is not shifted along the width direction of the transport path 2 by the first paper sheet shift mechanism 20. In other words, the first paper sheet shift mechanism 20 can selectively shift the paper sheets conveyed by the paper sheet conveyance mechanism 10 along the width direction of the conveyance path 2. In addition, each of the first skew rollers 22 and each of the second skew rollers 24 has a constant angle of skew with respect to the direction in which the conveyance path 2 extends. For this reason, when each first skew roller 22 and each second skew roller 24 are in contact with the paper sheet, the amount of movement of the paper sheet in the width direction of the conveyance path 2 (hereinafter also referred to as a shift amount). Is constant.

A gear 23c is attached to the other end of the rotating shaft 22a (the right end in FIG. 3). The right skew roller 22 of the pair of left and right skew rollers 22 is attached to the gear 23c. The gear 23e provided in the is connected through the gear 23d. For this reason, when the rotating shaft 22a is rotated, the right skew roller 22 is also rotated through the gears 23c, 23d, and 23e. In this way, the pair of left and right skew rollers 22 are rotated synchronously by the drive motor 23m.

  The right skew roller 24 of the pair of left and right skew rollers 24 is provided with a rotation shaft 24a, and the skew roller 24 rotates around the rotation shaft 24a. A rotating shaft 25a is connected to one end of the rotating shaft 24a (the right end in FIG. 3) via each screw gear 25b, and a driving motor 25m is connected to the rotating shaft 25a. ing. When the rotary shaft 25a is rotated by the drive motor 25m, the right skew roller 24 is rotated by rotating the rotary shaft 24a. A gear 25c is attached to the other end of the rotating shaft 24a (the left end in FIG. 3). The left skew roller 24 of the pair of left and right skew rollers 24 is attached to the gear 25c. The gear 25e provided in the is connected through a gear 25d. For this reason, when the rotating shaft 24a is rotated, the skew roller 24 on the left side is also rotated through the gears 25c, 25d, and 25e. In this way, the pair of left and right skew rollers 24 are rotated synchronously by the drive motor 25m.

Based on the paper sheet detection information sent from the exit side paper sheet detection sensor 54, the control unit 40 conveys the paper sheet by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30. It is determined whether or not it has been accurately moved to a predetermined position in the width direction of the path 2.

  Further, in the standby state of the paper sheet transport apparatus 1, the control unit 40 moves the skew rollers 22 and 24 of the first paper sheet shift mechanism 20 to the retracted positions as indicated by two-dot chain lines in FIG. It is supposed to be located at. Further, in the standby state of the paper sheet transport apparatus 1, the control unit 40 moves the upper guide part 32 and the lower guide part 34 of the second paper sheet shift mechanism 30 to the center position in the width direction of the transport path 2, respectively. It is supposed to be located at.

  Further, the control unit 40 presets the position of the paper sheet in the width direction of the transport path 2 before being sent to the first paper sheet shift mechanism 20 detected by the entrance-side paper sheet detection sensor 50. The transport path 2 by each of the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 based on the predetermined position (for example, the center position) of the paper sheets in the width direction of the transport path 2. The amount of movement of the paper sheet in the width direction (hereinafter also referred to as a shift amount) is calculated. Specifically, for example, the position of the paper sheet in the width direction of the transport path 2 before being sent to the first paper sheet shift mechanism 20 detected by the entrance-side paper sheet detection sensor 50 is the transport path. 2 in the width direction of the transport path 2 by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 when it is deviated by 10 mm from a predetermined position (for example, the center position) of the paper sheets in the width direction of 2. Is calculated by the control unit 40 so that the total amount of movement of the paper sheets (that is, the shift amount of the paper sheets by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30) is 10 mm.

  Here, in the present embodiment, as described above, the shift amount of the paper sheets by the first paper sheet shift mechanism 20 is constant, while the paper sheets by the second paper sheet shift mechanism 30 are constant. The shift amount can be adjusted. The first paper sheet shifting mechanism 20 is configured to selectively shift the paper sheet being conveyed in the width direction of the conveying path 2. Further, the upper limit value of the shift amount of the paper sheets by the second paper sheet shift mechanism 30 is determined in advance. That is, the movement amount when the upper guide part 32 and the lower guide part 34 move from the center position in the width direction of the transport path 2 to the end position of the transport path 2 is the amount of movement of the paper sheets by the second paper sheet shift mechanism 30. This is the upper limit of the shift amount. In addition, the control unit 40 calculates the paper sheets to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 calculated based on the detection result by the entrance-side paper sheet detection sensor 50. It is determined whether or not the shift amount is larger than the upper limit value of the shift amount of the paper sheets by the second paper sheet shift mechanism 30. Here, the shift amount of the paper sheet to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 calculated based on the detection result by the entrance-side paper sheet detection sensor 50 is: When the amount of shift of the paper sheets by the second paper sheet shift mechanism 30 is less than or equal to the upper limit value, the control unit 40 moves the paper sheets in the width direction of the transport path 2 by the first paper sheet shift mechanism 20. The paper sheets are shifted along the width direction of the transport path 2 only by the second paper sheet shift mechanism 30. Specifically, when the paper sheet is transported by the paper sheet transport mechanism 10, the first paper sheet shift mechanism 20 positions the skew rollers 22 and 24 at the retracted position indicated by the two-dot chain line in FIG. 2. Leave it alone. On the other hand, the shift amount of the paper sheet to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 is greater than the upper limit value of the paper sheet shift amount by the second paper sheet shift mechanism 30. If it is larger, the control unit 40 shifts the paper sheets along the width direction of the transport path 2 using both the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30. Specifically, when the paper sheet is transported by the paper sheet transport mechanism 10, each of the skew rollers 22 and 24 of the first paper sheet shift mechanism 20 is illustrated as one of the skew rollers. 2, the first paper sheet shift mechanism 20 shifts the paper sheets along the width direction of the transport path 2, and then the second paper sheet shift mechanism 30 moves the paper sheets. Is further shifted along the width direction of the transport path 2. As a result, the position in the width direction of the transport path 2 in the paper sheet after passing through the second paper sheet shift mechanism 30 is set in advance to a predetermined position of the paper sheet in the width direction of the transport path 2 ( For example, it is made to substantially coincide with the center position).

  Next, the operation of the paper sheet transport apparatus 1 having such a configuration (specifically, a paper sheet transport method by the paper sheet transport apparatus 1) will be described. The operation of the paper sheet transport apparatus 1 as described below is performed by the control unit 40 controlling each component of the paper sheet transport apparatus 1.

  The paper sheets sent to the paper sheet conveying apparatus 1 according to the present embodiment are conveyed from the upper side in FIG. 1 to the lower side (that is, from the right side to the left side in FIG. 2). The kind detection sensor 50 detects the position of the paper sheet in the width direction of the transport path 2. The positional information of the paper sheet in the width direction of the transport path 2 may be, for example, the distance from one side edge 16 of the transport path 2 to the paper sheet, or from the center in the width direction of the transport path 2. The distance to the center of the paper sheet may be used as long as the information can identify the position of the paper sheet. Further, the entrance-side paper sheet detection sensor 50 may also detect the length of the paper sheet in the width direction. Information detected by the entrance-side paper sheet detection sensor 50 is sent to the control unit 40. The controller 40 detects the position of the paper sheet in the width direction of the transport path 2 before being sent to the first paper sheet shift mechanism 20 detected by the entrance-side paper sheet detection sensor 50, and is set in advance. The paper sheets to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 based on a predetermined position (for example, the center position) of the paper sheets in the width direction of the transport path 2. The shift amount is calculated.

  More specifically, the control unit 40 calculates the paper to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 calculated based on the detection result by the entrance-side paper sheet detection sensor 50. It is determined whether the shift amount of the leaves is larger than the upper limit value of the shift amount of the paper sheets by the second paper sheet shift mechanism 30. Then, the shift amount of the paper sheet to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 is larger than the upper limit value of the paper sheet shift amount by the second paper sheet shift mechanism 30. If it is larger, the control unit 40 shifts the paper sheets along the width direction of the transport path 2 using both the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30. Specifically, when the paper sheet is transported by the paper sheet transport mechanism 10, each of the skew rollers 22 and 24 of the first paper sheet shift mechanism 20 is illustrated as one of the skew rollers. 2, the paper sheet is shifted along the width direction of the transport path 2 by the first paper sheet shift mechanism 20. Here, when the first paper sheet shifting mechanism 20 shifts the paper sheets to the left in FIG. 1 along the width direction of the transport path 2, each first skew roller 22 is retracted by the solenoid 26. The second skew roller 24 is kept in the retracted position while being moved to the shift position. As a result, the paper sheet transported along the transport path 2 by the paper sheet transport mechanism 10 comes into contact with each first skew roller 22, and the paper sheet is shifted to the left in FIG. The On the other hand, when the first paper sheet shifting mechanism 20 shifts the paper sheets to the right in FIG. 1 along the width direction of the transport path 2, each second skew roller 24 is moved from the retracted position by the solenoid 28. While moving to the shift position, each first skew roller 22 remains in the retracted position. As a result, the paper sheet transported along the transport path 2 by the paper sheet transport mechanism 10 comes into contact with each second skew roller 24, and the paper sheet is shifted to the right in FIG. The In FIG. 1, it is the entrance side paper that the paper sheet (indicated by reference symbol P <b> 1 in FIG. 1) before being sent to the first paper sheet shift mechanism 20 is located near the left end of the conveyance path 2 in FIG. 1. When detected by the leaf detection sensor 50, the paper sheet is shifted rightward in FIG. 1 by the first paper sheet shift mechanism 20, and after passing through the first paper sheet shift mechanism 20, the reference symbol P <b> 2. The example which moved to the position shown by is shown.

  Thereafter, when the paper sheet is delivered from the paper sheet transport mechanism 10 to the second paper sheet shift mechanism 30, the paper sheets are continuously moved by the rollers 36 and 38 of the second paper sheet shift mechanism 30. In this case, the upper guide portion 32 and the lower guide portion 34 of the second paper sheet shifting mechanism 30 are along the width direction of the transport path 2. And slide. For this reason, even if the position in the width direction of the transport path 2 of the paper sheet before being sent to the second paper sheet shift mechanism 30 is shifted from a predetermined position (for example, the center position), the second paper sheet shift is performed. By moving the paper sheets along the width direction of the transport path 2 by the mechanism 30, the paper sheets discharged from the second paper sheet shift mechanism 30 are positioned at a predetermined position in the width direction of the transport path 2. It will be sent. Specifically, the paper sheet delivered from the paper sheet transport mechanism 10 to the second paper sheet shift mechanism 30 is interposed between the driving roller 36 and the driven roller 38 of the second paper sheet shift mechanism 30. When sent to a certain nip portion, the upper guide portion 32 and the lower guide portion 34 slide along the width direction of the transport path 2. As a result, while the paper sheet is sandwiched between the drive roller 36 and the driven roller 38 in the second paper sheet shift mechanism 30, the paper sheet approaches a predetermined position along the width direction of the transport path 2. It can be moved. When the shift amount of the paper sheet to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 is less than or equal to the upper limit value of the paper sheet shift amount by the second paper sheet shift mechanism 30 The control unit 40 shifts the paper sheets along the width direction of the transport path 2 using only the second paper sheet shift mechanism 30.

  Here, the shift amount of the paper sheet by the second paper sheet shift mechanism 30 is calculated based on the detection result by the entrance-side paper sheet detection sensor 50. Specifically, when the paper sheets are not shifted by the first paper sheet shift mechanism 20, the paper sheets in the width direction of the transport path 2 before being sent to the first paper sheet shift mechanism 20. And a predetermined shift position of the paper sheet in the width direction of the transport path 2 (for example, the center position) is set to the second paper sheet shift mechanism 30. This is the amount of shift of paper sheets. On the other hand, when the paper sheets are shifted by the first paper sheet shift mechanism 20, the first paper sheet shift mechanism 20 and the first paper sheets calculated based on the detection result by the entrance-side paper sheet detection sensor 50 are used. The value obtained by subtracting the shift amount of the paper sheet by the first paper sheet shift mechanism 20 from the shift amount of the paper sheet to be shifted by the two paper sheet shift mechanism 30 is obtained by the second paper sheet shift mechanism 30. This is the shift amount of paper sheets.

  In FIG. 1, the paper sheet (indicated by reference symbol P2 in FIG. 1) after passing through the first paper sheet shift mechanism 20 is further shifted rightward in FIG. 1 by the second paper sheet shift mechanism 30. An example is shown in which, after passing through the second paper sheet shifting mechanism 30, it has moved to the position indicated by the reference symbol P3.

  According to the paper sheet transport apparatus 1 of the present embodiment, the first paper sheet shift mechanism 20 roughly shifts the paper sheets along the width direction of the transport path 2, and then the shift amount of the paper sheets is changed. By shifting the paper sheet to a predetermined position along the width direction of the transport path 2 by the adjustable second paper sheet shift mechanism 30, the paper sheet is accurately shifted to a predetermined position in the width direction of the transport path 2. In addition, the configuration of the entire apparatus can be simplified and inexpensive even when the conveyance speed of the paper sheet is increased. More specifically, the first paper sheet shifting mechanism 20 is less accurate than the second paper sheet shifting mechanism 30 in shifting the paper sheet to a predetermined position, but the skew rollers 22 and 24 are used. Thus, paper sheets can be conveyed at a high speed with a simple structure. On the other hand, since the second paper sheet shift mechanism 30 can adjust the shift amount of the paper sheet, the second paper sheet shift mechanism 30 can accurately shift the paper sheet to a predetermined position in the width direction of the transport path 2. Since the two-paper sheet shift mechanism 30 is expensive and the amount of shift of the paper sheets is limited, the number of the second paper sheet shift mechanism 30 installed unless the first paper sheet shift mechanism 20 is provided. Therefore, the configuration of the apparatus becomes complicated and expensive. For this reason, in the paper sheet transport apparatus 1 of the present embodiment, the advantages of both shift mechanisms can be obtained by combining the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30. become.

  In the present embodiment, instead of calculating the paper sheet shift amount by the second paper sheet shift mechanism 30 based on the detection result by the entrance-side paper sheet detection sensor 50, the intermediate paper sheet detection is performed. It may be calculated based on the detection result by the sensor 52. In particular, when the first paper sheet shift mechanism 20 has a simpler structure at the expense of the accuracy of shifting the paper sheets to a predetermined position, the shift amount by the first paper sheet shift mechanism 20 varies. There is a case. In this case, the shift amount of the paper sheet is calculated based on the detection result by the intermediate paper sheet detection sensor 52 immediately upstream of the second paper sheet shift mechanism 30, so that the second paper sheet The shift mechanism 30 makes it possible to bring the paper sheets to a predetermined position in the width direction of the transport path 2 with higher accuracy. Further, an exit-side paper sheet detection sensor 54 that detects the position of the paper sheet discharged from the second paper sheet shift mechanism 30 in the width direction of the transport path 2 may be provided. Information detected by the exit-side paper sheet detection sensor 54 is sent to the control unit 40. Based on the paper sheet detection information sent from the exit side paper sheet detection sensor 54, the control unit 40 conveys the paper sheet by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30. It is determined whether or not it has been accurately moved to a predetermined position in the width direction of the path 2.

  Moreover, in this Embodiment, the identification part which identifies paper sheets is provided in the upstream of the paper sheet conveyance mechanism 10 in the banknote depositing / dispensing machine etc. in which the paper sheet conveyance apparatus 1 is installed, The type and transport state of the paper sheet before being sent to the leaf transport mechanism 10 (specifically, the length in the width direction of the paper sheet, the position of the paper sheet in the width direction of the transport path 2, etc.) are detected. It may come to be. Specifically, the identification unit installed on the upstream side of the paper sheet transport mechanism 10 includes, for example, an image sensor, and based on the image of the paper sheet imaged by the image sensor, The length in the width direction, the position of the paper sheet in the width direction of the transport path 2, and the like are detected. In this case, the shift amount of the paper sheet to be shifted by the first paper sheet shift mechanism 20 and the second paper sheet shift mechanism 30 is the detection result of the paper sheet by the entrance-side paper sheet detection sensor 50. Instead of this, calculation is performed based on the detection result of the paper sheet by the identification unit. For this reason, it becomes possible to omit the installation of the entrance-side paper sheet detection sensor 50 on the upstream side of the first paper sheet shift mechanism 20. In the present embodiment, it is assumed that such an identification unit is also included in the paper sheet transport apparatus 1. Further, such an identification unit functions as a first paper sheet detection unit that detects the position of the paper sheet in the width direction of the transport path 2.

  In addition, the first paper sheet shift mechanism provided on the upstream side among the plurality of types of paper sheet shift mechanisms is not limited to the structure shown in FIGS. 1 to 3. As the first paper sheet shifting mechanism, a structure as shown in FIG. 6 may be used. FIG. 6 is a top view showing another configuration of the first paper sheet shifting mechanism in the paper sheet conveying apparatus according to the present embodiment. 6 is provided with a paper sheet transport mechanism 10 having the same configuration as that of the paper sheet transport apparatus 1 shown in FIG. 1. In FIG. 6, such a paper sheet transport mechanism is provided. The ten constituent members are indicated by the same reference numerals as in FIG.

  The first paper sheet shift mechanism 60 of the paper sheet conveying apparatus according to the modification shown in FIG. 6 is inclined in a direction inclined with respect to the extending direction of the conveying path 2 (that is, the vertical direction in FIG. 6). When the paper sheets conveyed between the pair of upper and lower circulation belts 12 and 13 come into contact with the skew rollers 62 and 64, the paper sheets are conveyed to the conveying path 2. Can be shifted in the width direction. Here, as shown in FIG. 6, among the plurality of skew rollers 62, 64, the first skew roller 62 and the second skew roller 64 are different from each other in the skew direction with respect to the extending direction of the conveyance path 2. ing. Further, as shown in FIG. 6, a pair of left and right first skew rollers 62 are provided so as to be aligned along the width direction of the transport path 2, and a pair of left and right second lines are aligned along the width direction of the transport path 2. A skew roller 64 is provided, and each second skew roller 64 is provided on the downstream side of each first skew roller 62 in the transport direction of the sheets in the transport path 2. The first skew rollers 62 and the second skew rollers 24 are rotated by drive motors (not shown).

  As shown in FIG. 6, the pair of left and right first skew rollers 62 are pivotally supported by the same rotation shaft 63, and when the rotation shaft 63 rotates, the first skew rollers 62 rotate in synchronization. It has become. Further, a drive motor (not shown) is connected to the rotation shaft 63, and the rotation shaft 63 is rotated by the drive motor. Further, the rotating shaft 63 swings in the direction of the arrow in FIG. 6 around an axis 63a provided at the right end of the rotating shaft 63 in FIG. More specifically, the rotation shaft 63 is provided with an angle adjustment mechanism (not shown) that adjusts the angle of the rotation shaft 63 with respect to the width direction of the conveyance path 2. 63 swings about a shaft center 63a between a first position as shown by a solid line in FIG. 6 and a second position as shown by a two-dot chain line in FIG. A friction member such as rubber is disposed on the outer peripheral surface of each first skew roller 62. Accordingly, when the rotation shaft 63 is positioned at the first position as indicated by the solid line in FIG. 6, each first skew roller 62 is placed on the surface of the paper sheet conveyed along the conveyance path 2. Contact with each other, the paper sheets are inclined with respect to the direction of each first skew roller 62 (that is, the direction in which the conveyance path 2 extends) by the frictional force acting between the paper sheet and each first skew roller 62. (The direction of the line). As a result, the conveyed paper sheets shift to the left in FIG. 6 along the width direction of the transport path 2. On the other hand, when the rotating shaft 63 is located at the second position as shown by a two-dot chain line in FIG. 6, the direction in which the conveyance path 2 extends and the direction of each first skew roller 62 are substantially matched. Thus, even if each first skew roller 62 comes into contact with the surface of the paper sheet transported along the transport path 2, the paper sheet is not shifted along the width direction of the transport path 2. In the example shown in FIG. 6, the angle adjustment mechanism is configured so that the rotation shaft 63 is at an arbitrary position between a first position as shown by a solid line in FIG. 6 and a second position as shown by a two-dot chain line in FIG. 6. It can be stopped with. For this reason, it becomes possible to adjust the angle of the direction of each first skew roller 62 with respect to the direction in which the conveyance path 2 extends, so that the shift amount of the first paper sheet shift mechanism 60 can also be adjusted. become.

  As shown in FIG. 6, the pair of left and right second skew rollers 64 are pivotally supported by the same rotation shaft 65, and when the rotation shaft 65 rotates, each second skew roller 64 rotates in synchronization. It is like that. Further, a drive motor (not shown) is connected to the rotation shaft 65, and the rotation shaft 65 is rotated by the drive motor. Further, the rotating shaft 65 swings in the direction of the arrow in FIG. 6 about an axis 65a provided at the left end of the rotating shaft 65 in FIG. More specifically, the rotation shaft 65 is provided with an angle adjustment mechanism (not shown) that adjusts the angle of the rotation shaft 65 with respect to the width direction of the transport path 2. 65 swings about a shaft center 65a between a first position as shown by a solid line in FIG. 6 and a second position as shown by a two-dot chain line in FIG. Further, a friction member such as rubber is disposed on the outer peripheral surface of each second skew roller 64. Accordingly, when the rotary shaft 65 is located at the first position as shown by the solid line in FIG. 6, each second skew roller 64 is placed on the surface of the paper sheet conveyed along the conveyance path 2. When the sheet is in contact, the frictional force acting between the paper sheet and each second skew roller 64 causes the paper sheet to be inclined with respect to the direction of each second skew roller 64 (that is, with respect to the direction in which the conveyance path 2 extends). (The direction of the line). As a result, the conveyed paper sheets shift to the right in FIG. 6 along the width direction of the transport path 2. On the other hand, when the rotation shaft 65 is located at the second position as shown by a two-dot chain line in FIG. 6, the direction in which the conveyance path 2 extends and the direction of each second skew roller 64 are substantially matched. Thus, even if each second skew roller 64 comes into contact with the surface of the paper sheet transported along the transport path 2, the paper sheet is not shifted along the width direction of the transport path 2. In the example shown in FIG. 6, the angle adjustment mechanism is configured so that the rotation shaft 65 is at an arbitrary position between a first position as shown by a solid line in FIG. 6 and a second position as shown by a two-dot chain line in FIG. 6. It can be stopped with. For this reason, it becomes possible to adjust the angle of the direction of each second skew roller 64 with respect to the direction in which the conveyance path 2 extends, so that the shift amount of the first paper sheet shift mechanism 60 can also be adjusted. become.

  In the paper sheet transport apparatus provided with such a first paper sheet shift mechanism 60, the first paper sheet shift mechanism 60 uses the paper sheet detection result by the entrance-side paper sheet detection sensor 50. The shift amount of the paper sheet is adjusted. Therefore, in addition to the second paper sheet shift mechanism 30, the first paper sheet shift mechanism 60 also adjusts the shift amount of the paper sheets so that the paper sheets can be more accurately positioned in the width direction of the transport path 2. Can be sent to.

  In addition, the second paper sheet shift mechanism provided on the downstream side among the plurality of types of paper sheet shift mechanisms is not limited to the structure shown in FIGS. 1, 2, and 4. As the second paper sheet shifting mechanism, a structure as shown in FIGS. 7 to 9 may be used. FIG. 7 is a perspective view showing another configuration of the second paper sheet shifting mechanism in the paper sheet conveying apparatus according to the present embodiment, and FIG. 8 is an upper surface of the second paper sheet shifting mechanism shown in FIG. FIG. 9 is a side cross-sectional view of the second paper sheet shift mechanism shown in FIG.

  The second paper sheet shift mechanism 70 shown in FIGS. 7 to 9 is different from the second paper sheet shift mechanism 30 shown in FIGS. 1, 2, and 4 in that an upper guide portion (not shown) and a lower guide are provided. The portion 74 is not slidable and is fixed in position, and the driven roller (not shown) and the driving roller 76 are respectively along the width direction of the transport path 2 with respect to the upper guide portion and the lower guide portion 74. And is slidable. Specifically, the second paper sheet shift mechanism 70 includes an upper guide portion (not shown) and a lower guide portion 74 that are fixedly disposed so as to be spaced apart from each other in the vertical direction at a slight distance. The conveyance path 2 through which the paper sheets are conveyed is formed between the upper guide portion and the lower guide portion 74. Further, as shown in FIGS. 7 to 9, the lower guide portion 74 is provided with a pair of left and right drive rollers 76 along the width direction of the transport path 2, and each upper guide portion includes A pair of driven rollers (not shown) are provided along the width direction of the transport path 2 so as to face the driving roller 76. Each drive roller 76 is provided with a drive shaft 79 for rotating the drive roller 76.

  Further, in the second paper sheet shift mechanism 70 shown in FIGS. 7 to 9, a substantially rectangular opening 74 a is formed in the lower guide portion 74 so as to correspond to each drive roller 76, and each drive roller 76. Protrudes upward from the upper surface of the lower guide part 74 through the corresponding openings 74a (see FIG. 9). In addition, a drive roller support portion 75 that supports each drive roller 76 is installed below the lower guide portion 74. Here, the driving roller support portion 75 is made of a substantially rectangular plate-like member, and is slidable along the width direction of the conveyance path 2 (that is, the left-right direction in FIG. 8). As a result, each drive roller 76 supported by the drive roller support portion 75 can also slide along the width direction of the transport path 2.

  Further, although not shown, a substantially rectangular opening is formed in the upper guide portion so as to correspond to each driven roller, and each driven roller passes through the corresponding opening and extends downward from the lower surface of the upper guide portion. It is designed to protrude. Further, a driven roller support portion for supporting each driven roller is installed above the upper guide portion. Here, the driven roller support portion is formed of a substantially rectangular plate-like member and is slidable along the width direction of the transport path 2. Accordingly, each driven roller supported by the driven roller support portion can also slide along the width direction of the transport path 2.

  In the second paper sheet shift mechanism 70 shown in FIG. 7 to FIG. 9, the paper sheet can be moved along the transport path 2 by the drive roller 76 and the driven roller along the width direction of the transport path 2. The conveyance member which conveys is comprised. Further, the upper guide portion and the lower guide portion 74 constitute a guide member in which the transport path 2 is formed therebetween. As described above, the guide member is fixed in position, and the conveyance member composed of the driving roller 76 and the driven roller moves along the width direction of the conveyance path 2 with respect to the guide member fixed in position. It can slide.

  Next, a mechanism for sliding the drive roller support portion 75 along the width direction of the transport path 2 will be described with reference to FIGS. As shown in FIGS. 7 and 8, below the lower guide portion 74, two guide rails 80 and 81 extending in parallel along the width direction of the transport path 2 are provided. A first lower member 75a is attached to the center position of one side edge of the drive roller support 75, and second positions are provided at both ends of the other side edge of the drive roller support 75, respectively. The lower member 75b and the third lower member 75c are attached. The first lower member 75 a is provided with a cylindrical member, and the first lower member 75 a is guided in the horizontal direction along the guide rail 80 by the guide rail 80 passing through the cylindrical member. It is like that. The second lower member 75b and the third lower member 75c are also provided with cylindrical members, respectively, and the guide rail 81 passes through these cylindrical members, so that the second lower member 75b and the third lower member 75b. The lower members 75c are guided in the horizontal direction along the guide rails 81, respectively.

  Further, an endless drive belt (not shown) disposed along the horizontal direction is provided below each guide rail 80, 81, and this drive belt includes a drive pulley (not shown). It is stretched around a plurality of pulleys (not shown). Further, in the second paper sheet shift mechanism 70, a drive motor (not shown) such as a stepping motor for rotating the drive pulley in both forward and reverse directions is provided. The second lower member 75b attached to the side edge portion of the drive roller support portion 75 is provided with a belt attachment portion (not shown), and this belt attachment portion is attached to the drive belt. According to such a configuration, when the drive motor rotates the drive pulley, the drive belt stretched around the drive pulley circulates and this causes the belt mounting portion to move in the horizontal direction. The lower member 75 b and the third lower member 75 c move along the guide rail 81. In this case, the first lower member 75a also moves along the guide rail 80, and the drive roller support portion 75 slides along the width direction of the transport path 2. In this way, each drive roller 76 supported by the drive roller support portion 75 also slides along the width direction of the transport path 2 within each opening 74 a of the lower guide portion 74. In the second paper sheet shift mechanism 70 shown in FIGS. 7 to 9, the rotation drive of the drive pulley by the drive motor is controlled by the control unit 40.

  Although not shown, the mechanism for sliding the driven roller support portion along the width direction of the transport path 2 is the same as the mechanism for sliding the drive roller support portion 75 described above along the width direction of the transport path 2. It has a configuration.

  In the second paper sheet shift mechanism 70 shown in FIGS. 7 to 9, compared with the second paper sheet shift mechanism 30 shown in FIGS. 1, 2, and 4, the upper guide portion and the lower guide portion 74 themselves. Need not be slid along the width direction of the conveyance path 2, and only the driving roller support portion 75 that supports each drive roller 76 and the driven roller support portion that supports each driven roller are aligned along the width direction of the conveyance path 2. Just slide it. For this reason, the weight of the member to be slid in the width direction is reduced, and thus the load on the drive motor that drives the drive roller support portion 75 and the driven roller support portion is also reduced. This improves the response when the drive rollers 76 and the driven rollers are slid along the width direction of the transport path 2 and the life of the drive motor that drives the drive roller support 75 and the driven roller support. Can be lengthened.

  In addition, the paper sheet transport apparatus 1 shown in FIG. 1 and the like includes an upper guide portion 32, a lower guide portion 34, a pair of left and right drive rollers 36, and a pair of left and right driven rollers 38 in the second paper sheet shift mechanism 30.

Further, each of the driving rollers 36 of the two sets of first combinations and each of the driving rollers 37 of the two sets of second combinations are rotated synchronously by a single driving motor. According to such a second paper sheet shift mechanism 30b, since the length of the second paper sheet shift mechanism 30b in the paper sheet conveyance direction can be further increased, the paper sheet is conveyed at a high speed. Even in this case, the shift amount of the paper sheets by the second paper sheet shift mechanism 30b can be further increased.

  Further, as the second paper sheet shifting mechanism, a structure as shown in FIG. 12 may be used. In the second paper sheet shift mechanism 30c shown in FIG. 12, on the upstream side and the downstream side of the combined body comprising the upper guide portion 32, the lower guide portion 34, the pair of left and right drive rollers 36, and the pair of left and right driven rollers 38, respectively. An upstream combination 90 and a downstream combination 95 are provided. The upstream combination body 90 includes an upper guide portion (not shown), a lower guide portion 91, a pair of left and right drive rollers 92, and a pair of left and right driven rollers (not shown).
