The third guide roller 89 is located on both sides of the second guide roller 88 in the axial direction, and is opposed to the first surface 36a of the tape 36 with a predetermined gap. The fourth guide roller 90 is at a position opposite to the position where the first guide roller 87 is removed in the width direction of the tape 36 and corresponds to the central portion of the bill 34 between the two tapes 36. Placed in position. The third guide roller 89 does not necessarily hold the tape 36, and therefore does not necessarily have to be a rubber roller.

  At the time of winding and rewinding the tape 36 with respect to the drum 37, the driving force is transmitted from the tape 36 that moves to the driving roller 85 that is in contact with the second surface 36b of the tape 36, and rotates integrally with the driving roller 85. The driving force is transmitted from the transmission roller 86 to the first guide roller 87, and the driving force is transmitted from the first guide roller 87 to the second to fourth guide rollers 88, 89, 90. Yes.

  The distance from the contact point between the drive roller 85 and the second guide roller 88 of the guide mechanism 84 and the contact point between the transmission roller 86 and the first guide roller 87 to the contact portion between the pair of belts 55a and 55b is as follows. The dimension is set to be shorter than the length of the bill 34 in the conveyance direction. As a result, the banknote 34 in the guide passage 44 is conveyed while being always held by at least one of the belts 55a and 55b and the guide mechanism 84. Further, from the contact point between the driving roller 85 and the second guide roller 88 of the guide mechanism 84 and the contact point between the transmission roller 86 and the first guide roller 87, the contact point P where the tape 36 is wound around the drum 37 is reached. The distance is set to a dimension shorter than the length of the banknote 34 in the conveyance direction. As a result, the banknote 34 wound and rewound on the drum 37 is always held by at least one of the drum 37 and the guide mechanism 84.

  A peeling claw 69 is rotatably attached to the roller shaft 93. The peeling claw 69 is provided with a plurality of ribs 69a for entering the gaps between the first to fourth guide rollers 87, 88, 89, 90 to guide the bill 34.

  In addition, the guide body 41 is provided with a banknote detector 95 that detects the banknote 34 in an area where the banknote 34 is conveyed together with the tape 36 in the swing passage 44. This banknote detection part 95 is comprised with an optical sensor, and detects the banknote 34 because sensor light is light-shielded when the banknote 34 passes.

  FIG. 8 shows a lower conveyance path 20 and a banknote storage and feeding device 23 that is a plurality of banknote storage units 21 arranged along the lower conveyance path 20. A timing sensor 97 that detects the banknotes 34 that are transported from the upper transport path 17 and stored in the banknote storage units 21 is disposed in the lower transport path 20.

  Note that the banknote storage and feeding device 23 used for the temporary storage unit 19, the banknote storage unit 21, and the banknote collection unit 22 has the same basic configuration and a different layout depending on the arrangement and orientation.

  Next, the operation of the bill storage / delivery device 23 will be described.

  First, the operation during bill storage will be described.

  In FIG. 8, the identified banknote 34 stored in the banknote storage unit 21 is transported from the upper transport path 17 to the lower transport path 20.

  When the banknote 34 conveyed to the lower conveyance path 20 is detected by the timing sensor 97, the branch lever 39 is connected to the lower conveyance path 20 in the banknote storage and feeding device 23 that is the banknote storage section 21 of the corresponding denomination that stores the banknote 34. The banknote 34 which advances and is conveyed is taken in the entrance / exit 35.

  At this time, the transport mechanism 40 of all banknote storage and feeding devices 23 is driven by the drive mechanism of the banknote handling machine 11 in the direction in which the banknotes 34 are stored. However, the motor 48 of the drum 37 of each bill storage / delivery device 23 is not driven unless the bill 34 is taken to a predetermined position in the bill storage / delivery device 23.

  The banknote 34 taken into the entrance / exit 35 is sandwiched between the belts 55a and 55b of the transport mechanism 40 and transported from the fixed passage 42 to the swing passage 44 in the guide body 41.

  In a direction corresponding to the banknote storage direction, the motor 48 of the banknote storage and feeding device 23 of the corresponding denomination that stores the banknote 34 after a predetermined time has elapsed since the banknote 34 being transported to the lower transport path 20 is detected by the timing sensor 97. The drum 37 is driven to rotate in the winding direction, and winding of the tape 36 is started by the drum 37.

  The rotation of the motor 48 is transmitted to the transmission mechanism to the reel shaft 49, but is not transmitted to the reel shaft 49 by the one-way clutch of the transmission mechanism. Therefore, the reel 38 attached to the reel shaft 49 via the torque limiter 50 does not rotate in the rewinding direction, and tension is applied to the tape 36 wound around the drum 37. Further, when the tension applied to the tape 36 becomes larger than the set torque value of the torque limiter 50, the torque limiter 50 slips and the reel 38 rotates in the rewinding direction. Therefore, the tape 36 is rewound from the reel 38 with a certain tension applied.

  The tape 36 rewound from the reel 38 in a tensioned state moves into the swing path 44 through the tape guide 73. At this time, as shown in FIG. 9C, when the position in the width direction of the tape 36 is normal with respect to the guide surface 75 of the tape guide 73, the center in the width direction of the tape 36 contacts the linear surface 75a. At the same time, both sides of the tape 36 in the width direction come into contact with the curved surface 75b, and the tape 36 is bent in the width direction. In this state, the tape 36 is subjected to contact resistance with the curved surfaces 75b on both sides in the width direction, the tape 36 is moved to the center by the tension of the tape 36, and the position of the tape 36 in the width direction is normal. Hold on. As shown in FIG. 9A, when the tape 36 is shifted to the left as shown in FIG. 9A, the frictional resistance between the left and left curved surfaces 75b of the tape 36 increases, as shown in FIG. 9B. Then, the tape 36 moves to the right side where the frictional resistance is small, and the position in the width direction of the tape 36 is corrected to a normal state as shown in FIG. 9 (c). Therefore, the tape 36 can be wound around the drum 37 with the position in the width direction of the tape 36 in a normal state.

  When the leading end of the banknote 34 in the conveyance direction reaches the guide mechanism 84, the tape 36 and the banknote 34 are sandwiched between the driving roller 85 and the second guide roller 88, and the tape 36 and the banknote 34 are joined together with the drum 37. Feed toward the outer peripheral surface of. Further, both side portions of the banknote 34 removed from the tape 36 are sandwiched between the transmission roller 86 and the first guide roller 87 and fed toward the outer peripheral surface of the drum 37. Further, the central portion of the banknote 34 removed from the tape 36 is fed toward the outer peripheral surface of the drum 37 by the fourth guide roller 90. Further, the tape 36 and the bill 34 fed by the second guide roller 88 are guided by the third guide roller 89 disposed on both sides in the axial direction of the second guide roller 88.

  The banknote 34 is sandwiched between the tape 36 and the outer peripheral surface of the drum 37 at a contact P at which the tape 36 contacts the outer peripheral surface of the drum 37, and the banknote 34 is wound around the drum 37 and stored together with the tape 36.

  When the banknote detection unit 95 detects the passage of the banknote 34 wound up and stored on the drum 37, the motor 48 is stopped to stop the rotation of the drum 37 and the storage of one banknote 34 is completed.

  Subsequently, when the banknote detection unit 95 detects the banknote 34 to be stored next, the motor 48 is rotationally driven again in a direction corresponding to the banknote storage direction, and the above-described storage operation is repeated.

  By performing such control, the banknote 34 can be wound around the drum 37 and stored at an appropriate banknote interval.

  Further, the contact roller 67 directly contacts the bill 34 between the two tapes 36 on the downstream side in the winding direction from the contact point P of the drum 37, and presses the bill 34 against the drum 37. As shown in FIG. 10 (FIG. 10 shows a state in which a plurality of banknotes 34 are wound around the drum 37), when the banknotes 34 are wound around the drum 37 with the tape 36, the portion of the banknotes 34 that the tape 36 contacts is changed. Although it is tightened, the portion of the banknote 34 other than the tape 36 is in contact with it easily swells, and the winding outer diameter of the drum 37 increases at the swelled portion of the banknote 34. When the contact roller 67 contacts the swollen portion of the banknote 34, the relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is appropriately set according to the exact winding outer diameter of the drum 37. Further, the bulge of the banknote 34 can be suppressed to some extent.

  1 (a) shows the minimum winding state of the tape 36 on the drum 37 (the banknote 34 is not stored), and FIG. 1 (b) shows the maximum winding state of the tape 36 on the drum 37 (the maximum position of the banknote 34). Large storage state).

  As shown in FIG. 1 (a), in the minimum winding state of the tape 36 on the drum 37, the guide body 41 is separated from the reel 38 around which the tape 36 is wound and enters the winding space of the drum 37. It is in a state closer to the drum 37 than the reel 38. Of the contact rollers 67, the first contact roller 67a contacts the drum 37, and the relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is maintained appropriately.

  When the tape 36 and the plurality of banknotes 34 are wound around the drum 37, the outer diameter of the drum 37 in the wound state of the tape 36 increases. By increasing the outer diameter of the drum 37 in the winding state of the tape 36, the contact roller 67 is pushed in the outer diameter direction of the drum 37, and the guide body 41 resists the bias of the spring 68 around the fulcrum 41a. And swings from the drum 37 side toward the reel 38 side.

  As shown in FIG. 1B, when the maximum winding state of the tape 36 in the drum 37 is approached, the guide body 41 enters the winding space of the reel 38 and comes closer to the reel 38 than the drum 37. . Of the contact rollers 67, the second contact roller 67b contacts the drum 37, and the relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is maintained appropriately.

  Since the rotation amount detector 51 detects the rotation amount of the motor 48 from the start of winding the tape 36 around the drum 37, the outer diameter of the drum 37 is determined based on the rotation amount of the motor 48, The motor 48 is controlled so that the rotation speed of the outer diameter portion of the drum 37 is constant, that is, the storage speed of the bills 34 is constant. Based on the rotation amount of the motor 48, a full state in which the tape winding amount or the bill storage amount is maximized is determined, and control is performed so as to stop storing the bills 34.

  Next, the operation at the time of bill feeding will be described.

  At the time of banknote feeding, the transport mechanism 40 of all banknote storage and feeding devices 23 is driven by the driving mechanism of the banknote handling machine 11 in the direction in which banknotes 34 are fed out.

  Of the plurality of bill storage / delivery devices 23, the motor 48 of the drum 37 of the bill storage / delivery device 23 that stores the types of bills 34 to be fed is sequentially driven to feed the denominations one by one to the lower conveyance path 20.

  By rotating the motor 48 of the bill storage and feeding device 23 in a direction corresponding to the bill feeding direction, the drum 37 rotates in the rewinding direction, and the tape 36 starts to be rewound from the drum 37.

  At the same time, the rotation of the motor 48 is transmitted to the reel shaft 49 through the transmission mechanism and the one-way clutch, the reel 38 rotates in the winding direction through the torque limiter 50 together with the reel shaft 49, and the tape 36 is taken up by the reel 38. start.

  At this time, regardless of the ratio of the tape winding amount between the reel 38 and the drum 37, the tape winding speed by the reel 38 is faster than the tape winding speed from the drum 37, and the tension is applied to the tape 36 wound by the reel 38. Take it.

  When the tension applied to the tape 36 becomes larger than the set torque value of the torque limiter 50, the torque limiter 50 slips, and the reel 38 moves in the same tape winding direction at a lower rotational speed than the reel shaft 49 with a constant torque applied. Rotate. Therefore, the tape 36 is wound around the reel 38 with a certain tension applied.

  Then, by rewinding the tape 36 from the drum 37, the banknote 34 is rewound together with the tape 36. The banknote 34 to be rewound from the drum 37 is peeled off from the peripheral surface of the drum 37 by the peeling claw 69 and sent to the guide mechanism 84 through the space between the tape 36 and the peeling claw 69.

  In the guide mechanism 84, the tape 36 and the bill 34 are sandwiched between the drive roller 85 and the second guide roller 88, and the tape 36 and the bill 34 are fed into the swing passage 44 together. Further, both side portions of the banknote 34 removed from the tape 36 are sandwiched between the transmission roller 86 and the first guide roller 87 and fed into the swing passage 44. Further, the central portion of the banknote 34 removed from the tape 36 is fed into the swing passage 44 by the fourth guide roller 40. Further, the tape 36 and the bill 34 fed by the second guide roller 88 are guided by the third guide roller 89 disposed on both sides in the axial direction of the second guide roller 88.

  At the time of rewinding the banknote 34 from the drum 37, as shown in FIG. 11A, a torn portion 34a that is torn at the front end in the rewinding direction of the banknote 34 is formed at the side part of the banknote 34 that is detached from the tape 36. If so, the torn portion 34a of the banknote 34 does not enter the swing passage 44 of the guide body 41 and is caught outside the guide body 41, and the banknote 34 may be further torn. Moreover, even if the banknote 34 is fed out without being severely broken, there is a problem that the banknote 34 is caught in the transport path and is likely to be jammed. Note that the torn portion 34a of the banknote 34 has the extension 64a of the first guide member 64, and therefore does not protrude from the surface of the banknote 34 on the extension 64a side, but the second guide member 65 side has a space. Therefore, since the curl wound around the drum 37 is attached, the second guide member 65 is likely to protrude from the surface of the banknote 34.

  Since the first guide roller 87 that is rotationally driven in the rewinding direction is disposed at the end of the second guide member 65 at a position deviated in the width direction of the tape 36, FIG. As shown in (c), when the surface of the torn portion 34a of the banknote 34 comes into contact with the first guide roller 87, the first guiding roller 87 reverses the direction to unwind the torn portion 34a of the banknote 34. Forcibly folded to the side, the torn portion 34 a of the bill 34 is sandwiched between the first guide roller 87 and the transmission roller 86, and is fed into the swing passage 44. Alternatively, as shown in FIGS. 11D and 11E, when the tip of the torn portion 34a of the bill 34 comes into contact with the first guide roller 87, the torn portion 34a of the bill 34 is moved by the first guiding roller 87. Is forcibly fed in the rewinding direction, sandwiched between the first guide roller 87 and the transmission roller 86, and fed into the swing passage 44.

  Further, since the fourth guide roller 90 that is rotationally driven in the rewinding direction is disposed at the end of the second guide member 65 at a position deviated in the width direction of the tape 36, Even if there is a broken portion in the central portion, the broken portion of the banknote 34 can be fed into the swing passage 44 as in the case of the first guide roller 87.

  Therefore, even if the tip of the banknote 34 to be rewound from the drum 37 is torn, the torn portion of the banknote 34 can be guided to the swing passage 44, and the banknote 34 can be greatly broken or 34 can be prevented from clogging.

  Of the tape 36 and the bill 34 which are rewound from the drum 37 and conveyed in the swing passage 44, the tape 36 is pulled out from the swing passage 44 via the guide roller 72 and wound on the reel 38, and the bill 34 is a pair of bills 34. The belts 55a and 55b are sandwiched and held, conveyed to the entrance / exit 35, and fed to the lower conveyance path 20.

  Further, the tape 36 drawn out from the swing passage 44 via the guide roller 72 is wound around the reel 38 through the tape guide 73. At this time, as shown in FIG. 9C, when the position in the width direction of the tape 36 is normal with respect to the guide surface 75 of the tape guide 73, the center in the width direction of the tape 36 contacts the linear surface 75a. At the same time, both sides of the tape 36 in the width direction come into contact with the curved surface 75b, and the tape 36 is bent in the width direction. In this state, the tape 36 is subjected to contact resistance with the curved surfaces 75b on both sides in the width direction, the tape 36 is moved to the center by the tension of the tape 36, and the position of the tape 36 in the width direction is normal. Hold on. As shown in FIG. 9A, when the tape 36 is shifted to the left as shown in FIG. 9A, the frictional resistance between the left and left curved surfaces 75b of the tape 36 increases, as shown in FIG. 9B. Then, the tape 36 moves to the right side where the frictional resistance is small, and the position in the width direction of the tape 36 is corrected to a normal state as shown in FIG. 9 (c). Therefore, the tape 36 can be wound around the reel 38 with the position in the width direction of the tape 36 in a normal state.

  Further, since the guide surface 75 of the tape guide 73 is curved so that the first surface 36a of the tape 36 wound around the reel 38 becomes a concave surface, even if the tape 36 reaches the reel 38 while being displaced in the width direction, Since the grounded side of the tape 36 is first grounded within the width of the reel 38, the grounding point of the reel 36 shifts from the side of the tape 36 displaced to the opposite side. Can be wound up normally.

  If the banknote 34 is fed out by one sheet, the banknote detection unit 95 detects the passage of the banknote 34 to be fed out, and then detects the leading edge of the banknote 34 to be fed out the next time by the banknote detection unit 95. Is stopped, and the rotation of the drum 37 is stopped. As a result, the leading end of the banknote 34 to be fed out next time is stopped at a predetermined feeding standby position in the swing passage 44, and the banknote 34 can be quickly fed out when the banknote 34 is next fed out.

  Also, when feeding out a plurality of banknotes 34, the motor 48 is continuously driven until the banknote detection unit 95 detects the passage of the banknotes 34 for the number of banknotes to be fed, and the banknote detection of the last banknote 34 to be fed out is detected. After the detection by the unit 95, when the banknote detection unit 95 detects the leading end of the banknote 34 to be fed out next time, the motor 48 is stopped and the feeding out of the plurality of banknotes 34 is completed.

  Further, when the tape 36 is rewound from the drum 37 and the banknote 34 is fed out, the outer diameter of the drum 37 in the wound state of the tape 36 becomes smaller. When the outer diameter of the drum 37 in the wound state of the tape 36 is reduced, the guide body 41 swings from the reel 38 side toward the drum 37 side around the fulcrum 41a by the bias of the spring 68.

  As shown in FIG. 1 (a), when approaching the minimum winding state of the tape 36 in the drum 37, the guide body 41 enters the winding space of the drum 37 and comes closer to the drum 37 than the reel 38. . Of the contact rollers 67, the first contact roller 67a directly contacts the banknote 34 wound around the drum 37 through the two tapes 36, and according to the outer diameter of the drum 37 being accurately wound, The relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is appropriately maintained.

  Since the rotation amount detection unit 51 detects the rotation amount of the motor 48 from the start of rewinding the tape 36 from the drum 37, the outer diameter of the drum 37 is determined based on the rotation amount of the motor 48, The motor 48 is controlled so that the rotation speed of the outer diameter portion of the drum 37 is constant, that is, the feeding speed of the banknote 34 is constant.

  As described above, in the bill storage / delivery device 23 of the present embodiment, the fulcrum 41a of the guide body 41 is in the region A parallel to the imaginary line L connecting the rotation center of the drum 37 and the rotation center of the reel 38. In the region A between the virtual line L2 orthogonal to the virtual line L1 from the rotation center of the drum 37 and the virtual line L3 orthogonal to the virtual line L1 from the rotation center of the reel 38, The rotation angle of the guide body 41 between the drum 37 and the reel 38 can be increased, and the winding space of the drum 37 and the reel 38 can be effectively used to increase the number of stored bills 34.

  For example, when the fulcrum 41a of the guide body 41 is arranged on the entrance / exit 35 side outside the region A, the guide body 41 interferes with the reel 38, and the rotation angle of the guide body 41 cannot be increased. On the other hand, by arranging the fulcrum 41a of the guide body 41 in the region A, the rotation angle of the guide body 41 between the drum 37 and the reel 38 can be increased.

  Since the fixed passage 42 is provided from the entrance / exit 35 toward the drum 37 and the swing passage 44 swinging around the fulcrum 41a located on the fixed passage 42 side is provided, the fulcrum 41a of the swing passage 44 is connected to a portion other than the entrance / exit 35. Since it can be arranged at an arbitrary position, the rotation angle of the swing passage 44 between the drum 37 and the reel 38 can be increased, and the winding space of the drum 37 and the reel 38 can be effectively used. Thus, the number of stored bills 34 can be increased.

  The fulcrum 41a of the guide body 41 and the swing passage 44 is outside the maximum outer diameter portion 37a in the maximum winding state in which the winding amount of the tape 36 and the banknote 34 to the drum 37 is maximum, and the maximum outer diameter portion. Since the distance to the rotation center of the reel 38 is smaller than the distance to the rotation center 37a and located at a substantially intermediate position between the maximum outer diameter portion 37a and the entrance / exit 35, the rotation angle of the guide body 41 and the swing passage 44 The number of stored bills 34 can be increased by effectively using the winding space of the drum 37 and the reel 38.

  Since the guide body 41 and the swing passage 44 are formed in a curved shape along the maximum outer diameter portion 37a in the maximum winding state in which the winding amount of the tape 36 and the banknote 34 to the drum 37 is maximized, The rotation angle of the guide body 41 and the swing passage 44 can be increased, and the number of stored bills 34 can be increased by effectively using the winding space of the drum 37 and the reel 38.

  Since the contact roller 67 of the guide body 41 contacts one of the tape 36 and the banknote 34 wound around the drum 37 and the downstream side in the winding direction with respect to the contact point P between the drum 37 and the tape 36, the guide The distance between the fulcrum 41a of the body 41 and the swing passage 44 and the contact point P toward the drum 37 is increased, the number of stored bills 34 is increased, and the minimum and maximum winding amounts of the tape 36 and the bills 34 by the drum 37 are increased. Even when the difference between the winding diameter of the drum 37 and the swinging angle of the guide body 41 is always properly maintained, the banknote 34 can be reliably wound and unwound from the drum 37. In particular, even if the winding outer diameter of the drum 37 changes, the change in the angle of the tip of the peeling claw 69 provided in the guide body 41 can be reduced with respect to the outer peripheral surface of the winding state of the drum 37, The rewinding of the banknote 34 from the drum 37 can be ensured.

  Further, since the contact roller 67 of the guide body 41 is in direct contact with the banknote 34 wound on the drum 37 with the tape 36, the winding outer diameter of the drum 37 and the guide are determined according to the exact winding outer diameter of the drum 37. The relationship with the rocking angle of the body 41 can always be kept appropriate, and the banknote 34 can be reliably wound and unwound from the drum 37.

  Since the contact roller 67 contacts the downstream side in the winding direction with respect to the contact point P of the tape 36 wound around the drum 37, the banknote 34 is wound around the drum 37 with the tape 36, and then the contact roller 67 contacts the banknote 34. 67 comes into contact, and it is possible to prevent the banknote 34 from being displaced due to contact with the contact roller 67.

  Since the contact roller 67 contacts the bill 34 between the two tapes 36 wound up at intervals in the axial direction of the drum 37, the bill 34 is in contact with the deviation of the tightening of the two tapes 36. In addition to being able to be pressed by the roller 67, the bulging portion of the banknote 34 between the two tapes 36 can be pressed by the contact roller 67 to suppress the bulging of the banknote 34.

  The first contact roller 67a of the contact roller 67 is wound around the drum 37 when the outer diameter of the tape 36 and the bill 34 wound around the drum 37 is smaller than the predetermined outer diameter. The second roller of the contact roller 67 when the outer diameter of the tape 36 and the banknote 34 wound around the drum 37 is larger than the predetermined outer diameter. The contact roller 67b comes into contact with the banknote 34 wound around the drum 37. Therefore, even if the winding amount of the drum 37 changes, the relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is The banknote 34 can be reliably wound and rewound on the drum 37 at all times.

  In particular, since the tip of the peeling claw 69 is worn by friction with the tape 36, when the winding outer diameter of the drum 37 is increased, the angle between the tip of the peeling claw 69 and the outer surface of the drum 37 being wound is small. Therefore, a gap may be generated between the tip of the peeling claw 69 and the outer surface of the drum 37 in the wound state, and the bill 34 may be peeled off and the tip of the claw 69 may not be reliably peeled off from the drum 37. Therefore, when the winding outer diameter of the drum 37 is large, the second contact roller 67b comes into contact with the banknote 34 wound around the drum 37, so that the tip of the peeling claw 69 is in contact with the outer surface of the drum 37 being wound up. The guide body 41 is swung so that the angle of the drum does not become small, the gap between the tip of the peeling claw 69 and the outer surface of the drum 37 in the wound state is prevented, and the bill 34 is peeled off to remove the drum at the tip of the claw 69. Can be reliably peeled off from 37.

  As shown in FIG. 10 by a two-dot chain line, the contact roller 67 is in contact with the bill 34 on the outer side of the two tapes 36 wound at intervals in the axial direction of the drum 37. It may be. In this case as well, the outer portion of the banknote 34 that swells away from the two tapes 36 can be pressed by the contact roller 67 to suppress the banknote 34 from bulging. In this case, the contact roller 67 may be brought into contact with only one side of both side portions of the banknote 34 that is outside the tape 36, or may be brought into contact with both sides. Even when the contact roller 67 is brought into contact with only one side of both side portions of the banknote 34 that is outside the tape 36, the contact roller 67 is located downstream of the contact point P of the tape 36 wound around the drum 37 in the winding direction. The contact roller 67 comes into contact with the banknote 34 after the banknote 34 is wound on the drum 37 with the tape 36 by the contact, so that the banknote 34 can be prevented from being displaced due to contact with the contact roller 67. . Further, the contact roller 67 may be in contact with the banknote 34 both between the two tapes 36 and on both outer sides of the tape 36.

  Further, the tape 36 is moved to the end of the guide passage 43 facing the drum 37 on the first surface 36a side of the tape 36 and deviated in the width direction of the tape 36. Since the first guide roller 87 that is rotationally driven in the direction corresponding to the direction is disposed, even if the leading end of the banknote 34 to be rewound from the drum 37 is torn, the torn part of the banknote 34 is It can be guided to the guide passage 43, and the tearing of the banknote 34 can be increased, and the banknote 34 can be prevented from being jammed in the transport path.

  The second guide roller 88 rotates coaxially and integrally with the first guide roller 87 and contacts the first surface 36a of the tape 36, and contacts the second surface 36b of the tape 36 to provide a second guide. A driving roller 85 that sandwiches the tape 36 between the roller 88 and transmits the driving force from the tape 36 is provided. Since the driving force is transmitted from the driving roller 85 to the first guide roller 87, the driving force of the tape 36 is used. The first guide roller 87 can be driven to rotate.

  A transmission roller 86 that rotates coaxially and integrally with the drive roller 85 is provided at a position off the width direction of the tape 36, and this transmission roller 86 contacts the first guide roller 87. A driving force can be transmitted to the first guide roller 87, and a portion where the tip of the banknote 34 in the rewind direction is torn between the first guide roller 87 and the transfer roller 86 is forcibly folded, and the guide It can be guided to the passage 43 to increase the tearing of the banknote 34 and prevent the banknote from being jammed in the transport path.

  Since the first guide roller 87 is in point contact with the transmission roller 86, it is possible to prevent the banknote 34 from winding and rewinding with respect to the drum 37 from being meandering and to easily extend wrinkles and swelling of the banknote 34.

  Since the second guide roller 88 makes point contact with the tape 36, it is possible to prevent the tape 36 winding and rewinding from the drum 37 from meandering. In addition, it is possible to prevent the banknote 34 from winding and rewinding with respect to the drum 37 from meandering and to easily extend wrinkles and swelling of the banknote 34.

  Since the third guide roller 89 that rotates integrally coaxially with the first guide roller 87 and guides the first surface 36a of the tape 36 is provided, the tape 36 can be reliably guided.

  Since the first guide roller 87 includes a fourth guide roller 90 that rotates coaxially and integrally with the first guide roller 87 at a position opposite to the position where the first guide roller 87 is disengaged in the width direction, Even if the tip of the banknote 34 in the unwinding direction is torn in the portion of the banknote deviated from both sides of the tape 36 by the first guide roller 87 and the fourth guide roller 90, the torn portion of the banknote 34 is guided through the guide path. Thus, it is possible to prevent the banknote 34 from being broken and to prevent the banknote from being jammed in the transport path.

  Since the first guide roller 87 and the transmission roller 86 are rubber rollers, the transmission of the driving force can be ensured and the leading end of the banknote 34 in the rewind direction is torn between the first guide roller 87 and the transmission roller 86. This makes it easy to forcibly fold the part.

  Since the second guide roller 88 and the fourth guide roller 90 are rubber rollers, the broken portion of the tip of the banknote 34 in the rewind direction can be reliably guided to the guide passage 43.

  In addition, since the tape 36 is curved in the width direction between the drum 37 and the reel 38 by the guide surface 75 of the tape guide 73, a shift in the width direction of the tape 36 moving between the drum 37 and the reel 38 can be prevented. Even if a deviation occurs, it can be automatically corrected.

  Since the guide surface 75 of the tape guide 73 is curved so that the first surface 36a of the tape 36 wound around the reel 38 becomes a concave surface, even if the tape 36 is displaced in the width direction, the displaced side of the tape 36 is the first side. The tape 36 can be normally wound within the width of the reel 38 by being grounded within the width of the reel 38.

  Since the guide surface 75 of the tape guide 73 has a central linear surface 75a and curved surfaces 75b curved from both sides of the linear surface 75a, an action of bringing the tape 36 toward the center of the guide surface 75 occurs, and the width direction of the tape 36 occurs. Can be made constant, and even if the tape 36 is displaced in the width direction, it can be automatically corrected.

  The tape guide moving means 77 moves the tape guide 73 in accordance with the winding amount of the tape 36 on the reel 38, and appropriately maintains the relationship between the winding amount of the tape 36 on the reel 38 and the position of the tape guide 73. Can do.

  Since the spring 80 of the tape guide moving means 77 urges the guide surface 75 of the tape guide 73 against the tape 36, the position in the width direction of the tape 36 can be kept constant, and the tape 36 is displaced in the width direction. Can also be corrected automatically.

  As shown in FIG. 12, when the outer diameter of the tape 36 and the banknote 34 wound around the drum 37 is larger than the predetermined outer diameter, the contact member 99 of the guide body 41 is larger than the predetermined outer diameter. May come into contact with the banknote 34 wound around the drum 37. The contact member 99 may be formed integrally with the first guide member 64, or may be formed separately from the first guide member 64 and attached to the first guide member 64.

  When the outer diameter of the tape 36 and the bill 34 wound on the drum 37 is smaller than the predetermined outer diameter, the contact roller 67 contacts the banknote wound on the drum 37. In addition, when the outer diameter of the tape 36 and the banknote 34 wound around the drum 37 is larger than the predetermined outer diameter, the contact member 99 of the guide body 41 is wound around the drum 37. Even if the winding amount of the drum 37 changes, the relationship between the winding outer diameter of the drum 37 and the swing angle of the guide body 41 is always maintained appropriately so that the banknote 34 with respect to the drum 37 is contacted. 34 winding and rewinding can be ensured.

  Further, instead of the first contact roller 67a and the second contact roller 67b, contact members corresponding to the first contact roller 67a and the second contact roller 67b may be provided in the first guide member 64. Good.

  In the above-described embodiment, the number of tapes 36 is not limited to two, and the banknotes 34 can be wound and rewound onto the drum 37 with only one tape 36.
