[0001]
BACKGROUND OF THE INVENTION
The present invention separates and stacks and stores two types of paper sheets such as banknotes, securities, and tickets having different dimensions, and separates and discharges paper sheets one by one from each storage unit. The present invention relates to a kind of storage and discharge device.
[0002]
[Prior art]
In a vending machine or the like, a storage device is incorporated that discriminates the type (amount of money, etc.) of a bill inserted into a bill insertion slot and transports it to a different storage unit for each type. In many cases, it is necessary to discharge the change for the inserted amount of banknotes. If this change includes banknotes, the banknotes of the denomination entered in the storage unit are calculated and returned to the discharge port. It is also necessary to make (ie discharge).
[0003]
2. Description of the Related Art Conventionally, a storage / discharge device that separates two types of banknotes and stores them in different storage units, and separates one of the banknotes from each storage unit and discharges them one by one. FIG. 12 shows a conventional apparatus. In this figure, reference numerals 200 and 202 denote storage units, which are arranged in two upper and lower stages, and store banknotes 204 of different denominations. The banknote 204 stored in the storage unit 200 is, for example, a 5,000 yen bill, and the banknote 204 stored in the storage unit 202 is, for example, a 1,000 yen bill.
[0004]
Between the storage units 200 and 202, billboards 206 and 206 are provided in the storage units 200 and 202, respectively, which support the bills 204 with a predetermined separation. First, the lower storage unit 200 will be described. A presser plate 208 that supports the bill 204 from below is provided in the storage unit 200 so as to be movable up and down. The holding plate 208 is biased upward by the coil spring 210.
[0005]
Reference numeral 212 denotes a bill presser arm which can be moved up and down to be positioned. The bill presser arm 212 is divided into left and right so as to engage with both edges parallel to the carry-in / out direction of the lower bill 204. The bill stand 206 faces the bill 204 from between the bill presser arms 212.
[0006]
Therefore, if the bill presser arm 212 is held in the lowered position, the bill 204 moves downward with the both edges engaged with the bill presser arm 212, and leaves the bill stand 206. On the other hand, if the bill presser arm 212 is held in the raised position, the bill 204 contacts or approaches the bill stand 206.
[0007]
A pair of protruding rollers 214 and 216 are provided between the bill bases 206 and 206. These protruding rollers 214 and 216 have their lower and upper edges facing the lower storage box 200 and the upper storage box 202 through windows provided in the billboards 206 and 206, respectively. Accordingly, when the bill presser arm 212 used in the lower storage unit 200 is in the raised position (position shown in FIG. 12), the ejecting rollers 214 and 216 come into contact with the lower bill 204.
[0008]
The configuration of the upper storage unit 202 is substantially symmetrical with the storage unit 200. Accordingly, corresponding parts are denoted by the same reference numerals and description thereof will not be repeated. The difference between the two is that the holding plate 208 is pushed up by the spring 210 in the storage unit 200, whereas the holding plate 208 is pushed down by the weight 216 on the storage unit 202.
[0009]
Rubber friction materials 214A and 216A are fixed to a part of the outer periphery of the protruding rollers 214 and 216, respectively. When the protruding rollers 214 and 216 rotate clockwise in FIG. 12 and the friction materials 214A and 216A come into contact with the upper surface of the bill 204, the uppermost bill 204 is moved leftward in FIG. 12 by the friction materials 214A and 216A. Sent. Similarly, in the upper storage unit 202, the contact / separation between the bill 204 and the ejection rollers 214 and 216 can be controlled by the vertical movement of the bill presser arm 212.
[0010]
Gate rollers 220 and 220 are provided outside the storage boxes 200 and 202 to separate and discharge the banknotes 204 sent out by the ejection rollers 214 and 216 one by one. Each gate roller 220 is formed by a feed roller 220A and a separation roller 220B, respectively.
[0011]
Note that belts are wound around these rollers with other rollers, and the bill 204 moves while being sandwiched between these belts. A one-way clutch is incorporated in the separation roller 220B and can be rotated only in the storing direction of the bills 204, and the rotation in the discharging direction is restricted.
[0012]
When the bill 204 is stored in the storage unit 200 or 202, the bill presser arms 212 and 212 move downward and upward, respectively, so as to be separated from each other. For this reason, the bill 204 is separated from the bill stands 206 and 206, and a space is formed between the bill 204 and the bill stand 206. The bills 204 that have passed between the lower gate rollers 220 and the bills that have passed between the upper gate rollers 220 are fed into the spaces formed in the storage units 200 and 202, respectively.
[0013]
  When the bills 204 are discharged one by one from the lower storage unit 200, the lower bill presser arm 212 is raised to the position shown in FIG. At this time, the banknote 204 in the storage unit 200 faces the rollers 214 and 216 and the presser plate facing the window of the billboard 206.208It is held between and. The banknote 204 is pressed against the protruding rollers 214 and 216 by the coil spring 210. For this reason, the tag presser arm 212 includes the protruding rollers 214 and 216 and the presser plate.208And move upward while squeezing both edges of the bill 204 held.
[0014]
When the banknote 204 is discharged from the lower storage unit 200, the ejection rollers 214 and 216 are synchronously rotated by a predetermined angle (for example, one rotation) clockwise in FIG. 12, and the uppermost banknote 204 is moved to the lower gate roller. Send to 220. At this time, due to the friction between the banknotes 204, the banknote 204 below the uppermost banknote 204 also moves in the same direction.
[0015]
When the uppermost layer and several lower bills 204 enter between the feed roller 220A and the separation roller 220B, only the uppermost bill 204 is fed in the discharge direction by the feed roller 220A, and the lower bill 204 is separated by the separation roller. Blocked by 220B. As a result, the banknotes 204 are separated one by one by the gate roller 220 and discharged.
[0016]
Similarly, when the banknote 204 of the upper storage unit 202 is discharged, the upper bill presser arm 212 is lowered. At this time, the lower bill presser arm 212 is also lowered to keep the lower bill 204 away from the ejection rollers 214 and 216. The banknote 204 is sandwiched between the protruding rollers 214 and 216 facing the window of the upper billboard 206 and the upper pressing plate 206, and is pressed by the protruding rollers 214 and 216 by the weight 218 placed on the upper pressing plate 208. The
[0017]
If the protruding rollers 214 and 216 rotate counterclockwise in FIG. 12 in this state, the bill 204 at the bottom layer of the storage unit 202 is sent to the upper gate roller 220. The banknotes 204 are separated by the gate roller 220, and only the lowermost sheet is discharged.
[0018]
[Problems to be solved by the invention]
The banknote storage / discharge device described above requires two sets of gate rollers 220 and 220 in order to store and discharge two types of banknotes 204. These gate rollers 220 and 220 need to be arranged in two upper and lower stages corresponding to the two storage parts 200 and 202 arranged in two upper and lower stages.
[0019]
For this reason, there is a problem that the number of rollers to be used and the number of belts when the belt is wound around the rollers increase, and the structure becomes complicated. If the gate rollers 220 and 220 are arranged in two upper and lower stages, the distance between the positions where the banknotes 204 of the gate rollers 220 and 220 are inserted becomes large. Since it is necessary to set the lower edge and the upper edge of the protruding rollers 214 and 216 to substantially the same height as the entrances of the bills 204 of these gate rollers 220 and 220, the diameters of the protruding rollers 214 and 216 are also large. Become. For this reason, the problem that the apparatus enlarges or the accommodation volume of the banknote 204 becomes small arises.
[0020]
Further, when the diameters of the protruding rollers 214 and 216 are increased, the distance from the contact point between the protruding rollers 214 and 216 and the bill 204 to the conveyance start position of the bill 204 of the gate rollers 220 and 220 is increased. The contact point between the ejection rollers 214 and 216 and the banknote 204 is a position where the banknote 204 is pushed out, and the conveyance start position of the gate rollers 220 and 220 is a position where the banknote 204 starts to be pulled out. Accordingly, when the distance between the two positions is increased, the leading end of the banknote 204 to be ejected buckles, and it becomes easy to generate a jam.
[0021]
Furthermore, the diameters of the feed rollers 220A and 220A are significantly smaller than the protruding rollers 214 and 216, and are almost half or less. For this reason, the protruding rollers 214 and 216 intermittently push the bill 204 into the small-diameter feed rollers 220A and 220A that are continuously rotating at a high speed. As a result, there is a problem that the front end of the banknote 204 is easily broken and a paper jam is likely to occur.
[0022]
The present invention has been made in view of such circumstances, and enables the downsizing of the apparatus and the enlargement of the banknote accommodation volume, thereby making it possible to make it difficult for paper jams to occur when paper sheets are discharged. An object of the present invention is to provide a storage / discharge device.
[0023]
[Structure of the invention]
  According to the present invention, the object is to horizontally store different types of paper sheets in a pair of storage units arranged in two upper and lower stages, and to separate and discharge the paper sheets one by one from each storage unit. In a storage and discharge device of the same type, two upper and lower paper sheets arranged horizontally with a predetermined interval between the two storage parts, and upper and lower peripheral edges of the upper and lower edges from the windows respectively provided on the two paper sheets. A projecting roller that faces the inside of the unit, a pair of upper and lower paper sheet pressing arms that lifts and lowers the paper sheets of both storage units to contact and separate the paper sheet from the projecting roller, and 2 from the outside of both storage units. One feed roller that faces between the sheets and rotates in the same speed and in the same direction as the protruding roller, and rotates in the discharge direction of the sheets facing the feed roller from above and below Is controlled and a pair of upper and lower sides allowed to rotate in the reverse direction And the release roller,A pair of free rollers that are coaxially held on each separation roller and rotatable in both directions, a belt wound around the feed roller, and a belt wound around each free roller and wound around the feed roller A pair of belts that carry paper sheets between them;The center of the feed roller and the center of the two separation rollersDroopingStraight lineAWhile located on the topThe belt wound around the feed roller and each free roller sandwiches the leading edge of the paper sheet at the same height before the vertical line A and generates a tensile force,By selectively raising and lowering the paper sheet holding arm and controlling the rotation direction of the feed roller and the protruding roller, the paper sheets are selectively stored in the storage units and separated and discharged from the storage units. This is achieved by a paper sheet storing and discharging device characterized by the above.
[0024]
  Here, the paper sheets are securities such as banknotes and checks, tickets, and the like. The feed roller and the protruding roller have almost the same diameter.do it, These are rotated in the same direction at the same speedRuTherefore, these drive mechanisms are simplified. For example, pulleys having the same diameter or substantially the same diameter may be fixed to these, and these pulleys may be belt-driven.
[0025]
The paper presser arm (note presser arm) engages near both edges parallel to the loading / unloading direction of the paper sheet, and the paper stand (the bill stand) supports the paper sheet inside the paper presser arm. Can be. In this case, both edges of the paper sheet can be squeezed (handled) as the paper pressing arm moves up and down, and the paper sheet can be more easily separated.
[0026]
The feed roller and the separation roller are arranged so as to deviate in the axial direction and overlap in the radial direction, and paper sheets are bent between the feed roller and the separation roller to prevent double feeding. it can.
[0027]
  A free roller that can rotate in both directions is provided on the same axis as the separation roller, and a sheet can be sandwiched between the free roller and the feed roller and conveyed in the storage / discharge direction. In this case, the paper sheet is sandwiched and conveyed between the belt wound around the feed roller and the belt wound around the free roller.At the same time, the center of the feed roller and the center of the two separation rollers are positioned on the vertical line A, and the belt sandwiches the leading edge of the paper sheet at the same height as that of the vertical line A to generate a tensile force. Therefore, the tip is not easily broken during discharge, and smooth discharge is possible.
[0028]

FIG. 5 is a side view of a storage / discharge device according to an embodiment of the present invention, and FIG. 6 is a plan view showing the drive system of the gate roller and the protruding roller. 7 and 8 are a rear view and a front view of the storage / discharge device, FIG. 9 is a view showing a state in which the bill is discharged from the storage portion, FIG. 10 is a view showing the feed roller drive mechanism, and FIG. It is a figure which shows the state to do. In addition, let the surface which has the insertion discharge port of a banknote in FIGS. 1-3 be a front here.
[0029]
1-3, the code | symbol 10 is a banknote conveying apparatus as a paper sheet conveying apparatus, and this is accommodated in vending machines, such as a tobacco and a drink can. The banknote transport apparatus 10 is assembled in a vertically long casing 12, and one side surface (left side surface) of the casing 12 is a door 14 that can be opened and closed. On the front surface (front surface) of the housing 10, a horizontal banknote insertion port 16 and a banknote discharge port 18 are arranged in parallel vertically.
[0030]
In the housing 12, an identification unit 22 that determines the type of the banknote 20 inserted from the insertion slot 16, and a transport unit 30 that leads to different storage units 24, 26, and 28 for each type of banknote 20 identified. And a temporary holding / discharging unit 32 for discharging the banknote 20 to be changed. The storage unit 24 stores “10,000 yen bills”, the storage unit 26 stores “5,000 yen bills”, and the storage unit 28 stores “1,000 yen bills”.
[0031]
The type of the banknote 20 inserted from the insertion slot 16 is identified by the identification unit 22. The conveyance unit 30 feeds the banknote 20 downward with the conveyance belt interposed therebetween, and flappers 34 and 36 provided in the middle change the course of the bills and guide them to the respective storage units 24, 26 and 28 (see FIGS. 2 and 3). . Since “5000 yen bills” and “1000 yen bills” are used as the change, the 1,000 yen / 5,000 yen payout unit 38 provided between the banknote storage units 26, 28 is the storage unit 26. , 28, and the banknotes 20 are extracted one by one and sent to the transport unit 30. The transport unit 30 is sent to the temporary storage / discharge unit 32 by the flappers 34 and 36 and the flapper 40. That is, the conveyance unit 30 performs storage conveyance for guiding the banknote 20 to the storage units 24, 26, 28 and discharge conveyance for guiding the banknote 20 from the storage units 26, 28 to the banknote discharge port 18.
[0032]
Here, as shown in FIG. 2, the 1,000 yen / 5,000 yen payout section 38 accommodates the storage section 26 by pushing down the 5,000-yen bill one by one from the top and taking out one by one from the top. To the transport unit 30. Further, the 1,000 yen bills are pushed up and stored one by one from below in the storage unit 28 and taken out from the bottom one by one and guided to the transport unit 30.
[0033]
The banknotes 20 for discharge pass through the flappers 34, 36, and 40, and are temporarily stored in the temporary storage / discharge unit 32. When all the banknotes 20 to be changed remain here, they are discharged together into the discharge port 18. That is, a presser roller 32A is provided on the upper surface of the banknote 20 guided here so as to be movable up and down. The presser roller 32A normally takes in the banknote at the raised position, and a predetermined type and a predetermined number of banknotes to be changed are accumulated. The presser roller 32A descends and presses the banknote 20 from above, and discharges a plurality of banknotes 20 together.
[0034]
Note that the banknote 20 guided from the 1,000 yen / 5,000 yen payout unit 38 to the transport unit 30 is detected by the double feed detection sensors 42 and 42 as to whether or not it is double fed (FIG. 2). That is, it is detected whether or not two or more banknotes 20 are sent while being overlapped. When it is determined to be double feed, the flapper 40 prevents the banknote 20 from entering the temporary storage / discharge unit 32 and the other flapper 44 on the downstream side rotates to guide the banknote 20 to the reject unit 46.
[0035]
A banknote detection sensor 48 that detects the passage of the banknote 20 at an appropriate position is attached to the transport unit 30. The banknote detection sensor 48 and the double feed detection sensor 42 are optical ones, and are composed of a light emitting element and a light receiving element that face each other across the path of the banknote 20. A blade 50A having elasticity on the rotary shafts 50, 52, and 54 of the discharge ports for discharging the bills 20 from the transport unit 30 to the storage unit 24 of the 10,000 yen bill, the temporary storage / discharge unit 32, and the reject unit 46, respectively. , 52A, 54A are attached (FIG. 2). These blades 50 </ b> A, 52 </ b> A, 54 </ b> A hold the banknote 20 discharged from the transport unit 30 from above and prevent its floating.
[0036]
Next, a part of the transport unit 30 will be described with reference to FIG. FIG. 4 shows a portion for guiding the stacked banknotes 20 from the transport unit 30 to the reject unit 46. The banknote 20 returned to the transport unit 30 from the 1,000 yen / 5,000 yen dispensing unit 38 is lifted by being sandwiched between a longitudinal belt 56 shown in FIGS. . As shown in FIG. 4, the belt 62 wound around the rotating shaft 54 and the rotating shaft 60 is in contact with the long belt 56. A belt 68 wound around a rotating shaft 64 and a rotating shaft 66 that support the flapper 44 so as to be freely movable is in contact with the belt 62 from above. A one-way clutch is incorporated in the rotating shaft 54.
[0037]
The belts 56, 62, and 68 change in the traveling direction in both directions. That is, when storing and conveying the banknote 20, the belt 56 runs downward and the belt 62 runs counterclockwise in FIG. 4, and when the banknote 20 is discharged, the belt 56 runs upward and the belt 62 runs clockwise. . Therefore, the rotating shaft 60 rotates forward and backward corresponding to the conveyance direction of the banknote 20.
[0038]
Next, the 1,000-yen / 5,000-yen payout unit 38 and the storage units 28 and 26, which are the banknote separating and discharging apparatus according to the present invention, will be described. In this embodiment, the 1,000 yen / 5,000 yen dispensing section 38 takes in the 1,000 yen / 5,000 yen banknotes 20 and separately stacks and stores them in the storage sections 28, 26. 26, the banknotes 20 are separated and discharged one by one.
[0039]
The dispensing unit 38 is configured in substantially the same manner as the apparatus described in FIG. A significant difference from that of FIG. 12 is that the feed roller 104A and the feed-side separation roller 104A ′ are arranged on one shaft. As shown in FIG. 5, a pair of protruding rollers 100 and 102 having friction members 100 </ b> A and 102 </ b> A and a gate roller group 104 are provided. The gate roller group 104 is formed of one feed-side separation roller 104A ′ and two separation rollers 104B and 104C in a side view.
[0040]
A feed-side separation roller 104A ′ is fixed near the axial center of the feed roller 104A. A rubber friction member 104A ″ is attached to a part of the outer periphery of the feed side separation roller 104A ′ (see FIG. 9). The feed side separation roller 104A ′ and the separation rollers 104B and 104C are as shown in FIG. In the vicinity of the center, they are alternately displaced with a gap so as to deviate from each other in the axial direction and overlap in the radial direction, and the banknote 20 is bent so as to wave when passing the banknote 20 through the gap.
[0041]
The feed roller 104A is a pulley around which the belt 106A (see FIG. 7) is wound, and is held on the shaft of the feed-side separation roller 104A ′ and can freely rotate in both directions. Free rollers 104D and 104E that can rotate in both directions are provided at both ends of the separation rollers 104B and 104C, and belts 106B and 106C are wound around these free rollers 104D and 104E. FIG. 7 is a view of the gate roller group 104 as viewed from the left side in FIG.
[0042]
The reason why the banknotes 20 are waved in the gaps between the feed-side separation rollers 104A ′ and 104B and 104C is to make it easy to separate the banknotes 20 and prevent their double feed. As described with reference to FIG. 12, the separation rollers 104B and 104C can be rotated only in one direction (banknote storing direction) by the one-way clutch, and the rotation in the discharge direction is restricted.
[0043]
Here, the feed-side separation roller 104A 'and the protruding rollers 100 and 102 have substantially the same outer diameter, and these rotate in the same direction at the same speed by driving the belt. That is, as shown in FIG. 6, the feed-side separation roller 104A ′ is driven in both forward and reverse directions by another drive system shown in FIG.
[0044]
The drive system of the feed side separation roller 104A ′ includes one motor 105 capable of forward and reverse rotation as shown in FIG. The rotation of the motor 105 is transmitted to the pulley 105C via the timing belt 105A and the clutch 105B, and is also transmitted to the feed-side separation roller 104A ′ via the timing belt 105D and the electromagnetic clutch 105E. Here, the pulley 105C is wound with the belt 106A wound around the feed roller 104A.
[0045]
When the electromagnetic clutches 105B and 105E are connected and the motor 105 rotates in the direction of arrow A (clockwise) in FIG. 10, the pulley 105C rotates in the clockwise direction. Therefore, the belt 106A and the feed roller 104A run and rotate in the direction of arrow A, and the feed-side separation roller 104A ′ also rotates in the same direction. When the electromagnetic clutches 105B and 105E are connected and the motor 105 rotates in the direction of arrow B (counterclockwise) in FIG. 10, the belt 106A travels in the direction of arrow B, and feed roller 104A and feed-side separation roller 104A ′. Rotates in the direction of arrow B. The electromagnetic clutches 105B and 105E are provided so that the start / stop timing of the feed roller 104A can be set independently of the start / stop timing of the feed-side separation roller 104 ′ and the ejection rollers 100 and 102. It is. For example, banknotes can be separated and sent one by one in the feeding direction without being continuous.
[0046]
The rotation of the feed roller 104A is transmitted to the protruding rollers 100 and 102 by the belts 110 and 112, and these rotate at the same speed in the same direction. Since the feed roller 104A can freely rotate in both directions with respect to the axis of the feed-side separation roller 104A ′, both the rollers 104A and 104A ′ rotate separately.
[0047]
A holding plate 116 is horizontally supported on the bottom surface of the storage portion 26 of the 5,000-yen banknote 20 via coil springs 114 and 114. On the upper surface of the presser plate 116, a laminated body L of 5,000 yen bills 20₁Is placed.
[0048]
Laminate L₁The laminated body L is located above the protruding rollers 100 and 102 in the width direction outside.₁A tag presser arm 118 that can be engaged with both edges in the width direction is attached to be movable up and down. The tag presser arm 118 is located above the lower edges of the protruding rollers 100 and 102 in the raised position shown in FIG. For this reason, the laminated body L pushed up by the coil spring 114₁The upper surface of the roller contacts the protruding rollers 100 and 102.
[0049]
On the inner side in the width direction of the bill presser arm 118, a bill stand 120 that is long in the length direction of the bill 20 is attached to prevent the bill 20 from wavy. The billboard 120 is divided into a total of three parts between the two split rollers 100 and 102 and both outer sides in the width direction (see FIG. 8).
[0050]
When the bill presser arm 118 is lowered, as shown in FIG.₁The laminated body L is engaged with both edges in the width direction of the sheet from above and compressing the spring 114₁Press down. In this state, the laminate L₁The laminate L is separated from the protruding rollers 100 and 102.₁The banknote 20 sent by the conveyance unit 30 and the gate roller 104 enters the gap between the protruding rollers 100 and 102. FIG. 2 shows this state. At this time, the feed roller 104A rotates counterclockwise.
[0051]
After the banknote 20 is taken into the storage unit 26 in this way, when the banknote 20 is discharged, the bill presser arm 118 rises. 5 and 9 show this state. While the bill holder arm 118 is being lifted,₁The banknote 20 located on the upper surface of the banknote 20, that is, the banknote 20 taken in the state shown in FIG. 2, is pressed against the ejection rollers 100 and 102. When the bill presser arm 118 is further raised, the arm 118 is moved to the laminated body L pressed by the protruding rollers 100 and 102.₁The uppermost banknote 20 is moved above the banknote 20 while handling both edges of the banknote 20 with the bill stand 120. Therefore, if the protruding rollers 100 and 102 rotate clockwise in this state, the laminate L₁The banknotes 20 located in the uppermost layer can be discharged one by one.
[0052]
The payout device 38 stores and discharges the 5,000 yen bill from the lower storage portion 26, and also stores and discharges the 1,000 yen bill from the upper 1,000 yen bill storage portion 28. L in FIGS.₂Indicates a stack of 1,000 yen bills. This mechanism is substantially symmetrical with the above-described mechanism of the storage unit 26 of the 5,000 yen bill. Therefore, the description is not repeated by attaching the same reference numerals to the corresponding portions of the storage portion 26. The difference between the two is that the holding plate 116 is pushed up by the coil spring 114 in the storage portion 26, whereas the holding plate 116 is pushed down by the weight 122 placed on the holding portion 28.
[0053]
Accordingly, when the bill 20 is taken into the upper storage portion 28, the upper bill pushing arm 118 is raised as shown in FIGS. 5, 9, and 11 and is carried in between the feed roller 104A and the free roller 104E. The bill 20 is guided to a space below the bill pushing arm 118.
[0054]
When the banknote 20 is discharged from the storage unit 28, the bill presser arm 118 is lowered to bring the banknote 20 into contact with the upper edges of the rollers 100 and 102. If the feed-side separation roller 104A ′ and the ejection rollers 100 and 102 are rotated counterclockwise in this state, the banknote 20 is reliably separated into one sheet by the gate roller 104, and the free roller above the feed roller 104A. It is conveyed by the belt 106 wound around the roller 104E.
[0055]
That is, the banknote 20 is fed by the ejection rollers 100 and 102, and the leading edge of one banknote 20 separated by the feed side separation roller 104 </ b> A ′ and the separation roller 104 </ b> C is detected by the banknote detection sensor 48. After the leading edge is detected, the conveying force of the belt 106A is transmitted to the banknote 20 from the position P where the belts 106A and 106C come into contact with the leading edge of the banknote 20.
[0056]
After a predetermined time has elapsed after the sensor 48 detects the leading edge of the banknote 20, and after the conveying force of the belt 106A is transmitted to the banknote 20, the electromagnetic clutch 105E (FIG. 10) is disconnected and stops transmitting the driving force. . Accordingly, the feed-side separation roller 104A ′ and the protruding rollers 100 and 102 are stopped. Thereafter, the banknote 20 is discharged while being sandwiched between the belts 106A and 106C while being rubbed against the feed-side separation roller 104A ′ and the protruding rollers 100 and 102. At this time, the feed-side separation roller 104A ′ and the friction members 104A ″, 100A, 102A of the protruding rollers 100, 102 are not in contact with the banknote 20, and the metal surface of the rollers 104A ′, 100, 102 is on the banknote 20. Since it will contact, the banknote 20 slips smoothly and is discharged | emitted.
[0057]
Here, based on FIG. 9, the operation | movement at the time of discharge | emission of the lower accommodating part 26 is demonstrated in detail. In FIG. 9, the centers of the feed roller 104A and the separation rollers 104B and 104C are located on the vertical line A. The amount of meshing between the feed-side separation roller 104A ′ and the separation rollers 104B and 104C (the amount of overlap on the outer periphery) is maximized near the straight line A. Accordingly, the separating action for preventing the banknotes 20 discharged by the protruding rollers 100 and 102 from overlapping is maximized in the vicinity of the straight line A.
[0058]
On the other hand, at the front end of the banknote 20, a tensile force is generated by the belt 106 in the vicinity of the position P where the belts 106A, 106B, and 106C contact before the straight line A. Therefore, in order to separate and discharge the banknote 20 smoothly, this position (position where the tip of the banknote 20 is gripped) P is as close as possible to the straight line A, and the banknote 20 separation position (the straight line where the pulleys 104A ′, 104B and 104C overlap). It is desirable that the height is the same as the position on A).
[0059]
According to this embodiment, the feed roller 104A can be made larger in diameter than that of the conventional device (FIG. 11) and the radius of curvature thereof can be increased, so that the position P can be brought closer to the straight line A, and The height can be made to approach the height of the separation position of the banknote 20. For this reason, the front-end | tip of the banknote 20 cannot be bent easily, and it becomes possible to perform separation discharge | emission smoothly.
[0060]
【The invention's effect】
  According to this invention, there is one feed roller, and the number of rollers in the gate roller groupAnd belt numberTherefore, it is possible to reduce the size of the apparatus. Further, since the diameter of the protruding roller can be reduced, the storage capacity of the paper sheets can be increased. In addition, by reducing the diameter of the protruding roller, the center distance between the protruding roller and the feed roller can be narrowed, and the leading edge of the paper sheet is less likely to be broken during discharging, and clogging during discharging is less likely to occur.
[0061]
Furthermore, since the diameter of the feed roller can be increased as compared with the conventional apparatus, the position (P) where the feed roller grips the leading edge of the paper sheet is brought close to the position (A) where the overlap of the paper sheets is separated and the height thereof is increased. The difference can be reduced. For this reason, the leading edge of the paper sheet can be surely guided to the position (P) where the tensile force is generated to prevent the leading edge from being bent, and smooth discharge can be achieved.
