DETAILED DESCRIPTION

[0099] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the invention are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.

[0100] In the most general form of the inventive concept the note directing device comprises two note feeders. However, in other embodiments the note directing device may comprise more than two note feeders, e.g. three note feeders. It should be understood that when features are described in an embodiment comprising only two note feeders the description is also applicable to embodiments comprising three note feeders.

[0101] In a first embodiment of the invention, shown in FIG. 1-3, the note directing device 1 comprises a first note feeder 11, a second note feeder 12 and a brushed roller 2. In a first operation mode the note directing device 1 is configured to control the movement of a bank note 10 such that the bank note 10 is transported from the first note feeder 11 to the second note feeder 12. The first note feeder 11 is configured to feed the bank note 10 along a direction A, tangential to a surface of the bank note 10, such that a leading edge 14 of the bank note 10 is presented to the brushed roller 2. The brushed roller 2 is configured to engage with the bank note 10 and rotate in a rotational direction B such that the leading edge 14 of the bank note 10 is directed towards the second note feeder 12. The second note feeder 12 is configured to accept the leading edge 14 of the bank note 10 and to feed the bank note 10 along a direction C, tangential to a surface of the bank note 10. FIG. 1-3 represents a time series, seen in a side view perspective, of the transport of a bank note 10. The time series start with FIG. 1 corresponding to a point in time when the bank note 10 is presented to the brushed roller 2. The first note feeder 11 has a feeding direction A such that the leading edge 14 of a bank note 10 is presented to the brushed roller 2. The time series continues with FIG. 2 corresponding to a point in time when the brushed roller 2 has started to bend the bank note 10 such that the leading edge 14 has started to move towards the second note feeder 12. The time series further continues with FIG. 3, corresponding to the point in time when the second note feeder 12 has started feeding the bank note 10.

[0102] A perspective view of one embodiment of the invention is seen in FIG. 4. Here, the bank note 10 is shown in a position corresponding to the point in time shown in FIG. 3.

[0103] FIG. 5 a-d show various embodiments of the brushed roller 2, seen in perspective view. The brushed roller 2 comprises an axis 4 and bristles 6, each bristle 6 being attached at one end to the axis 4 and extending radially from said axis 4, the distribution of bristles 6 extending along a longitudinal direction E of the axis 4. FIG. 5a shows an embodiment wherein the bristles 6 are distributed evenly along the longitudinal direction E of the axis 4. FIG. 5b shows an embodiment wherein the bristles 6 are arranged in a plurality of sets 8 of bristles 6, wherein the sets are arranged to be distributed along the longitudinal direction E of the axis 4. The sets 8 of bristles 6 may be arranged such that longitudinal gaps are formed between them. The sets 8 may be individually replaceable. For example, each set 8 may comprise a collar 9 with attached bristles 6. The collar 9 may be slid onto the axis 4 and fixed to the axis 4 using a set screw or another fastening means. The sets 8 of bristles 6 may of course also be attached directly to the axis 4 as seen in FIG. 5c. The sets 8 of bristles 6 do not have to be identical as exemplified in FIG. 5d. The extension of a set 8 along the longitudinal direction E of the axis 4 may vary from one set 8 to another set 8. Furthermore, the bristles 6 may vary from one set 8 to another set 8 in terms of length, stiffness, electrical conductivity etc.

[0104] FIG. 6 shows various embodiments of the brushed roller, seen in side view. The bristles 6 may be distributed evenly or unevenly around the axis 4. Circumferential gaps 20 may be provided between the bristles 6 such that the leading edge 14 of a bank note 10 may enter in between the bristles 6. The size of the circumferential gaps 20 may vary around the circumference of the brushed roller 2 such that bunches 22 of bristles 6 are formed. The circumferential gaps 20 between bristles within a bunch 22 may be small while the circumferential gap 20 between different bunches 22 may be large. The large circumferential gaps 20 may e.g. be configured to effectively accept the leading edge 14 of the bank note 10. The small circumferential gaps 20 may e.g. be configured to give a desired flexibility of the bunch 22 of bristles 6 by setting how densely the bristles 6 are spaced. The number of bristles 6 and the distribution around the circumference of the brushed roller 2 may e.g. be configured according to the intended rotational speed B of the brushed roller 2 or the bending stiffness of the individual bristles. For example, a faster rotational speed may require larger circumferential gaps 20. Furthermore, a bunch 22 of bristles 6 comprising a large amount of soft bristles 6 may have the same stiffness as a bunch 22 of bristles 6 comprising a small amount of stiff bristles 6.

[0105] The bristles 6 may be made from a number of materials, regardless of how they are distributed around the axis 4. Examples of bristle 6 materials are polymers, nylon, polyamide, PVC, metal, or natural fibers. In one embodiment, bristles 6 are made from an electrically conductive material such as e.g. a polymer material (e.g. thermoplastic material or polycarbonate material) containing e.g. carbon powder or carbon fibers. Bristles 6 made of an electrically conductive material may be grounded, e.g. via an electrically conductive axis 4, such that charges may be removed from a bank note 10 as it passes. It should be understood that the bristles 6 do not need to be identical around the circumference the brushed roller 2. The bristles 6 may e.g. have different length or be made of different materials to provide a combined effect of improved directing of bank notes 10.

[0106] FIG. 7a-c show various types of note feeders, here exemplified as variations of the first note feeder 11 seen in a side view. However, it should be understood that these figures may represent a first note feeder 11, a second note feeder 12, or a third note feeder 13. Furthermore, all the note feeders in a note directing device 1 does not have to be of the same type. The note feeder may have an entry side and an exit side and may therefore act as either the first note feeder 11 or the second note feeder 12. Brushed rollers 2 may be arranged at both the entry side and the exit side such the note feeder may act simultaneously as a first note feeder 11 in relation to brushed roller 2 at one side (entry side or exit side) of the note feeder 11 and as a second note feeder 12 in relation to brushed roller 2 at an opposite side (exit side or entry side) of the note feeder 12. The note feeder may be configured such that the feeding direction may be reversed, e.g. by putting a driving mechanism in reversed gear. The note feeder may feed a bank note 10 in a direction tangential to the surface of the bank note 10. However, it may be the configuration of the note feeder which defines whether the direction tangential to the surface of the bank note 10 is horizontal, vertical or any other direction, i.e. by feeding the bank note 10 the note feeder may define which direction the bank note moves in. The note feeder may feed the bank note 10 by supplying a force tangential to the surface of the bank note 10, wherein the force may be transmitted to the bank note 10 through friction. It should be understood that the surface of the bank note refers to one of the two surfaces of the bank note 10. The bank note 10 being considered to be an essentially two-dimensional object.

[0107] The note feeder may comprise two co-acting belts 24 as illustrated in the embodiments in FIG. 7a and FIG. 7b. The belts 24 are comprised of any suitable material, including but not limited to, rubber. Each belt 24 may be connected to and rotate around at least two pulleys 26. At least one of the at least two pulleys 26 connected to a belt 24 may be powered such that the belt 24 is driven forward, other pulleys may be idling. The two co-acting belts 24 may be arranged adjacent to each other such that a bank note 10 may be sandwiched between them, both belts 24 being in contact with the bank note 10 simultaneously and pinching the bank note 10 between them. The bank note 10 may in this manner be fixed between the belts 24 such that it does not fall off. By rotating the pulleys 26 connected to the first belt 24 in a rotational direction opposite to the rotational direction of the pulleys 26 connected to the second belt 24 the two belts 24 may co-act and the bank note 10 may move together with the two co-acting belts 24, wherein direction of movement for the bank note 10 may be a direction A which is tangential to the surface of the bank note 10. By reversing the rotational direction of the powered pulleys 26 the direction of movement for the bank note 10 may be reversed. The powered pulleys 26 of the two belts 24 may be driven by individual power sources or by the same power source. Using the same power source may have the advantage that it is easier to achieve the same speed for the two co-acting belts 24. Driving the co-acting belts 24 with the same speed reduces the wear on the bank notes 10 and reduces the risk of jams.

[0108] The belts 24 may be wider than the width of the bank note 10 such that the belts 24 cover the entire bank note 10 surface, e.g. to fully protect the bank note 10 during transport. The belts 24 may also be more narrow than the bank note 10 such that part of the surface of the bank note 10 is exposed during transport. This may e.g. enable a detector to detect the denomination, origin or condition of the bank note 10 during transport. Furthermore, the note feeder may also comprise several pairs of co-acting belts, e.g. one pair of co-acting belts 24 arranged at one lateral edge of the bank note 10 and another pair of co-acting belts 24 arranged at the other lateral edge.

[0109] The co-acting belts 24 may be arranged such that the feeding direction is the same at the entry side as at the exit side. Alternatively, the co-acting belts may be arranged such that the feeding direction at the entry side is different from the feeding direction at the exit side. For example, a bank note 10 may be accepted at the entry side and fed in a direction tangential to the surface of the bank note, the direction being a vertical direction, the route of the co-acting belts 24 may then be such that at the exit side the bank note 10 is fed in a direction tangential to the surface of the bank note, the direction being a horizontal direction. Such changes in the feeding direction may be implemented using additional pulleys 26.

[0110] The entry side and exit side of the note feeder may be arranged by placing the pulleys 26 of the opposite co-acting belts adjacent to each other as seen in the embodiment in FIG. 7a or separated as seen at the exit side in the embodiment in FIG. 7b. In another embodiment the note feeder may comprise two co-acting rollers 28 without any belts as seen in FIG. 7c. Such co-acting rollers 28 may be placed adjacent to each other and rotate in opposite direction to each other, thus operating in a manner analogous to co-acting belts 24.

[0111] In a preferred embodiment the bristles 6 of the brushed roller 2 are soft so that the brushed roller may be mounted in such a manner that the bristles conform to the surface of at least one of the note feeders by bending. FIG. 8a shows an example of such an embodiment wherein the bristles conform to the surfaces of both the first note feeder 11 and the second note feeder 12. A brushed roller 2 with soft bristles 6 may be mounted so that it reaches far into the corner formed by e.g. co-acting belts 24 at the entry or exit side of the note feeder. FIG. 8a illustrates, in a side view of one embodiment of the note directing device 1, how the bristles may reach all the way in to the point where the co-acting belts 24 of the first note feeder 11 release the bank note 10 as well as all the way in to the point where the co-acting belts 24 of the second note feeder 12 accepts the bank note 10. In contrast, FIG. 9a illustrates, in a side view, a note directing device according to prior art where a rubber wheel 30 is used instead of a brushed roller. The rubber wheel 30 may not reach as far into the corners of the note feeders.

[0112] It is also preferable with an embodiment wherein the bristles 6 of the brushed roller 2 are soft enough to flex and bend when in contact with the bank note 10. As seen in FIG. 8b, a side view of one embodiment of the note directing device 1, both the bristles and the bank note 10 may bend during the directing of the bank note 10. This means that the bristles 6 may bend more when a stiffer bank note 10 passes than when a softer bank note 10 passes. This may allow a stiff bank note to take a path with a slightly larger curvature. Bristles 6 that flex when in contact with the bank note 10 may also have the advantage that the brushed roller 2 may engage a longer segment of the bank note than a solid rubber wheel could. FIG. 9b illustrates, in a side view, a note directing device according to prior art where a rubber wheel 30 is used instead of a brushed roller 2 and wherein the segment of the bank note which is engaged by the rubber wheel 30 is much shorter than when a brushed roller 2 is used as in FIG. 8b.

[0113] The primary purpose of the note feeders may be to feed the bank note 10 and the primary purpose of the brushed roller 2 may be to direct the leading edge 14 of the bank note 10 during the transition from one note feeder to another. However, a note feeder may also be arranged to take part in directing the leading edge 14. FIG. 10 shows one embodiment, in a side view, wherein the first note feeder 11 and the second note feeder 12 comprise co-acting belts 24. In FIG. 10 the leading edge 14 of the bank note 10 has not yet reached the point where the co-acting belts 24 come together to start feeding the bank note 10. However, by providing support and friction to the bank note 10 one of the belts 24 of the second note feeder 12 may help directing the leading edge 14 towards the point where both belts 24 of the second note feeder 12 get a grip of the bank note 10 and feed it along. Furthermore, a brushed roller 2 may also be arranged to take part in feeding the bank note 10. Due to friction between the bristles 6 and the bank note 10 the brushed roller 2 may provide a force in a direction tangential to the surface of the bank note 10.

[0114] The leading edge 14 of the bank note 10 may be presented to the brushed roller 2 after it has left the first note feeder 11, as shown e.g. in FIG. 1. However, the leading edge 14 of the bank note 10 may also be presented to the brushed roller 2 while still in contact with the first note feeder 11, as shown in FIG. 10 b. In such a configuration the leading edge 14 may e.g. rest against one of the two co-acting belts 24 of the first note feeder 11. The brushed roller 2 may subsequently peel off the bank note 10 by dragging the bristles 6 over the surface of the belt 24 while the bristles 6 conform to the surface of the belt 24 by bending. Since the bristles 6 in such a configuration may engage a longer segment of the bank note 10 and the belt 24 than a solid rubber wheel 30 would, the redirecting of the bank note 10 may be more fault tolerant. Even if the bank note 10 is not redirected at the first impact with the first bristles of the rotating brushed roller 2 another bristle 6 may follow to make another attempt. Furthermore, if the bristles 6 may bend, the brushed roller 2 may allow the bank note 10 to take a slightly different path from the first note feeder 11 to the second note feeder 12 than a bank note 10 that is redirected at first impact without the bank note 10 being damaged. In contrast, if a solid rubber wheel 30 was used and the leading edge 14 was not redirected at first impact with the rubber wheel 30 it would possibly not be possible to redirect it once the leading edge has passed the contact point of the rubber wheel 30 and the belt 24 without the bank note 10 turning back on itself, thereby risking crumpling or folding.

[0115] The note feeders and the brushed roller 2 may be moving constantly or only when a bank note 10 is anticipated. The note feeders may be operated such that the feeding speed of the bank note 10 is the same for the first note feeder 11 and second note feeder 12. The feeding speed may also be slightly different. When the second note feeder 12 has accepted the bank note 10, the first note feeder 11 may go into an idling mode such that the bank note 10 is being pulled by the second note feeder 12. However, in a preferred embodiment both note feeders feed the bank note simultaneously at the same speed. The feeding speed may be considered to be the linear speed at which the note feeder's contact area to the bank note 10 is moving.

[0116] The brushed roller 2 may have a rotational speed such that the end of the bristle 6 that is furthest away from the axis 4 is moving with a linear speed that is faster than the speed of the bank note 10 being fed by the first 11 or the second note feeder 12. However, the rotational speed may also be such that the end of the bristle 6 that is furthest away from the axis 4 is moving with a linear speed that is the same or slower than the speed of the bank note 10 being fed by the first 11 or the second note feeder 12.

[0117] The speed of the note feeders and brushed roller 2, may be controlled by individual drivelines. However, the note feeders and brushed roller 2 may also be powered by the same driveline wherein the speed of the note feeders and brushed roller 2, relative to each other, may be set using e.g. gears. By using individual drivelines or a single driveline with gears one could e.g. set the rotational speed of the brushed roller 2 such that the end of the bristle 6 that is furthest away from the axis 4 is moving with a linear speed that is faster than the speed of the bank note 10. According to an embodiment, the rotational speed of the brushed roller 2 may be set such that the end of the bristle 6 that is furthest away from the axis 4 is moving with a linear speed that is 1.5 to 2 times faster than the speed of the bank note 10. The rotational speed may also be dependent on the bristle 6 length and the size of the circumferential gaps 20 between the bristles, in addition to the speed of the bank note 10. Thus the rotational speed could be set such that at least one bristle 6 engages the bank note 10 within the time it takes the bank note 10 to travel a distance, the distance being half the length of a bristle 6, after the bank note 10 being presented to the brushed roller 2.

[0118] In one embodiment the direction of the note feeders and the brushed roller 2 may be reversed such that the direction of movement of the bank note 10 may be reversed. For example, the feeding direction of the first note feeder 11, the second note feeder 12 and the brushed roller 2 may all be set individually by changing the direction of their individual drivelines or in the case of a common driveline changing gears individually. However, the direction of all the note feeders and the brushed roller 2 may also be simultaneously reversed by e.g. changing the direction of a common driveline or having the common driveline always drive in one direction and controlling how the power is transferred to the note directing device 1 with a reverse gear. FIG. 11 a-b show, in side view, an embodiment of a note directing device 1 wherein the direction of the bank note may be reversed.

[0119] FIG. 11a shows a note directing device in a first operation mode, wherein the bank note 10 moves along a first path F from the first note feeder 11 to the second note feeder 12. The first note feeder 11 has a feeding direction A such that the leading edge 14 of a bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the second note feeder 12. The second note feeder 12 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder. The second note feeder 12 further has a feeding direction C which allows the second note feeder 12 to accept the bank note 10 and feed it away from the brushed roller 2.

[0120] FIG. 11b shows a note directing device in a second operation mode, wherein the bank note 10 moves along a second path G from the second note feeder 12 to the first note feeder 11. The feeding directions A and C as well as the rotational direction B are reversed as compared to FIG. 11a. The second note feeder 12 has a feeding direction C such that the leading edge 14 of a bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the first note feeder 11. The first note feeder 11 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder. The first note feeder 11 further has a feeding direction A which allows the second note feeder 12 to accept the bank note 10 and feed it away from the brushed roller 2.

[0121] In one embodiment the note directing device 1 may act as a route selector for a bank note 10. FIG. 12 a-d show an embodiment wherein a first note feeder 11, a second note feeder 12, a third note feeder 13 and a brushed roller 2 are configured such that at least four different paths may be selected. The note directing device 1 in FIG. 12 a-d has note feeders comprising co-acting belts. In this embodiment the first and the third note feeder has a common belt 32. A common belt 32 may improve the accuracy of the note directing device 1 as the common belt 32 may facilitate the directing of the leading edge 14 from one note feeder to the other. However, it should be understood that other embodiments, not comprising a common belt, also are possible.

[0122] FIG. 12a shows a note directing device in a first operation mode, wherein the bank note 10 moves along a first path F from the first note feeder 11 to the second note feeder 12. The first note feeder 11 has a feeding direction A such that the leading edge 14 of the bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the second note feeder 12. The second note feeder 12 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder. The second note feeder 12 further has a feeding direction C which allows the second note feeder 12 to accept the bank note 10 and feed it away from the brushed roller 2.

[0123] FIG. 12b shows a note directing device in a second operation mode, wherein the bank note 10 moving along a second path G from the second note feeder 12 to the first note feeder 11. The feeding directions A and C as well as the rotational direction B are reversed as compared to FIG. 12a. The second note feeder 12 has a feeding direction C such that the leading edge 14 of the bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the first note feeder 11. The first note feeder 11 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder. The first note feeder 11 further has a feeding direction A which allows the second note feeder 12 to accept the bank note 10 and feed it away from the brushed roller 2.

[0124] FIG. 12c shows a note directing device in a third operation mode, wherein the bank note 10 moving along a third path H from the first note feeder 11 to the third note feeder 13. The first note feeder 11 has a feeding direction A such that the leading edge 14 of a bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the third note feeder 13. The third note feeder 13 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder 13. The third note feeder 13 further has a feeding direction which allows the third note feeder 13 to accept the bank note 10 and feed it away from the brushed roller 2.

[0125] FIG. 12d shows a note directing device in a fourth operation mode, wherein the bank note 10 moves along a fourth path I from the third note feeder 13 to the first note feeder 11. The feeding directions A and J as well as the rotational direction B are reversed as compared to FIG. 12c. The third note feeder 13 has a feeding direction J such that the leading edge 14 of a bank note 10 is presented to the brushed roller 2. The brushed roller 2 has a rotational direction B which directs the leading edge 14 of the bank note towards the first note feeder 11. The first note feeder 11 is positioned such that the leading edge 14 approaching from the brushed roller 2 may enter the note feeder. The first note feeder 11 further has a feeding direction A which allows the first note feeder 11 to accept the bank note 10 and feed it away from the brushed roller 2.

[0126] It should be understood that the first note feeder 11, the second note feeder 12, and the third note feeder 13 may have various orientations relative to each other. In FIG. 12 a-d the note feeders are oriented such that a bank note 10 may move from the first note feeder 11 to the second note feeder by making a 90° left turn and move from the first note feeder 11 to the third note feeder by travelling straight. However, a configuration as shown in FIG. 13 is also possible. In FIG. 13 the note feeders are oriented such that a bank note 10 may move from the first note feeder 11 to the second note feeder by making a 90° right turn and move from the first note feeder 11 to the third note feeder by making a 90° left turn.

[0127] In one embodiment of the invention a note directing device 1 is a part of a cash recycling apparatus 34, as seen in FIG. 14. In such an apparatus a note access opening 36 may be provided in the form of e.g. a slit in the casing of the cash recycling apparatus 34. A bank note 10 which is inserted into the note access opening 36 may e.g. be transported along a first path F to a note storage unit 38. The bank note inserted into the note access opening 36 may e.g. enter in between two co-acting belts of a first note feeder 11. In a first operation mode the first note feeder 11 may transport the bank note 10 to a brushed roller 2 which directs the bank note 10 to a second note feeder 12. The second note feeder 12 may then transport the bank note 10 to a note storage unit 38 wherein the bank note may be stored. Thus the first operation mode may perform a bank note 10 deposit into the note storage unit 38. Analogously, the bank note 10 may, in a second operation mode, be transported from the note storage unit 38 to the note access opening 36 by e.g. reversing the feeding direction A of the first note feeder, the rotational direction B of the brushed roller and the feeding direction C of the second note feeder, as compared to the first operation mode, so that the bank note 10 travels along a second path G. Thus the second operation mode may perform a bank note 10 withdrawal from the note storage unit 38.

[0128] It should be understood that the paths which the bank note 10 travels in the first and the second operation mode do not necessarily need to be opposite to each other. For example, the bank note 10 may travel along one path from the note access opening 36 via the first 11 and second note feeder 12 to the note storage unit 38 for a deposit but then travel along another path from the note storage unit 38 via the second note feeder 12 and a third note feeder 13 to the note access opening 36. The brushed roller 2 may be used to select which path the bank note takes. It should also be understood that a cash recycling apparatus 34 comprising a note directing device 1 with a first 11, a second 12 and a third note feeder 13 may further comprise additional note storage units 38. For example, if the first note feeder 11 is connected to the note access opening 36 the second 12 and third note feeder 13 may be connected to different note storage units 38. Furthermore, the third note feeder may also be connected to a fourth and a fifth note feeder via a brushed roller 2. Thus, even further note storage units may be connected. These may e.g. be used for notes of different denominations or different origins. Some of the note feeders may also be connected to detection routes where various features of the bank notes 10, e.g. denomination, origin etc., may be determined.

[0129] A note directing device 1 may also or alternatively be used for selecting whether a bank note 10 is to be transported towards a storage of bank notes 10 in the apparatus 34 or transported to be output from the apparatus 34 if the bank note is rejected.

[0130] The note storage unit 38 may be implemented in many ways. One way is illustrated in FIG. 15. A first film 40 and a second film 42 are wound around a note storage drum 44. Bank notes 10 may be fed in between the first 40 and the second 42 film and thus spooled onto the note storage drum 44. Thus the first 40 and a second 42 film acts both as a note feeder and as a part of the note storage drum 44. The first 40 and the second 42 films may be fed onto the note storage drum 44 from film storage drums 46. A further description of note storage drums 44 may be found in EP1466303.

[0131] FIG. 16 illustrates a method for directing a bank note 10 in a note directing device 1, wherein the bank note 10 can be directed along a path by controlling a first note feeder 11, a brushed roller 2, and a second note feeder 12, wherein the brushed roller 2 comprises an axis 4 and bristles 6, each bristle 6 being attached at one end to the axis 4 and extending radially from said axis 4, the distribution of bristles 6 extending along a longitudinal direction E of the axis. The method comprises receiving a path selection signal 102 and in response: set the first note feeder 104, set the brushed roller 106, and set the second note feeder 108. If the note directing device 1 further comprises a third note feeder 13, the method may further comprise the step of setting the third note feeder 110.

[0132] The path selection signal may be e.g. a transistor-transistor logic (TTL) signal, a RS-232 serial signal, or a USB signal. The signal may emanate from a processor unit e.g. as a response to a user request to e.g. withdraw cash. It may also emanate from a bank note validation unit. The bank note validation unit may e.g. detect that a bank note 10 has a certain denomination, wherein the denomination requires a certain path. The bank note validation unit may also or alternatively detect whether a bank note 10 is to be accepted or rejected by the apparatus 34, wherein an accepted bank note 10 may be transported for storage of the bank note 10 and a rejected bank note 10 may be transported to be output from the apparatus 34. The path selection signal may also be a combination of several signals.

[0133] If the path selection signal indicates a desired bank note 10 movement along a first path F from the first note feeder 11 via the brushed roller 2 to the second note feeder 12 then the first note feeder 11 may be set 104 such that the first note feeder 11 presents the leading edge 14 to the brushed roller 2. This may be done by setting the feeding direction A such that the bank note 10 moves towards the brushed roller 2 and setting a suitable feeding speed such that the brushed roller 2 may direct the leading edge 14. The feeding speed may be generic and preselected, e.g. a single feeding speed suitable for bank notes 10 of different origin and condition may be used always. However, the feeding speed may also be specific to the bank note 10 approaching the brushed roller 2, e.g. a detector signal may indicate that the approaching bank note 10 is of a specific type, requiring a specific feeding speed.

[0134] In further response to the first path selection signal the brushed roller 2 may be set 106 to have a rotational direction B and a rotational speed such that it engages the bank note 10 presented by the first note feeder 11 and directs the leading edge 14 of the bank note 10 towards the second note feeder 12. A suitable rotational direction B may be a direction wherein the interaction between the bank note 10 and the brushed roller 2 together with the interaction between the bank note 10 and gravity forces the leading edge 14 to move from the first note feeder 11 to the second note feeder 12. A suitable rotational direction B may also be the rotational direction B which directs the leading edge along a short path, rather than a long path, from the first note feeder 11 to the second note feeder 12. A suitable rotational speed B may be a speed adapted to the inertia of the bank note 10, allowing the bank note 10 to change direction in a controllable manner. A suitable rotational speed B may also be a speed which ensures that the leading edge 14 starts to be redirected before it passes the axis 4 of the brushed roller 2.

[0135] The rotational speed may be generic and preselected, e.g. a single rotational speed suitable for bank notes 10 of different origin and condition may be used always. However, the rotational speed may also be specific to the bank note 10 approaching the brushed roller 2, e.g. a detector signal may indicate that the approaching bank note 10 is of a specific type, requiring a specific rotational speed.

[0136] In further response to the first path selection signal the second note feeder 12 may be set 108 such that it accepts the leading edge 14 of the bank note 10 from the brushed roller 2. This may be done by setting the feeding direction C such that the accepted leading edge 14 of the bank note 10 moves away from the brushed roller 2 and setting a suitable feeding speed. A suitable feeding speed for the second note feeder 12 may e.g. be a speed which do not put unnecessary strain on the bank note 10 if it is still being fed by the first note feeder 11. The feeding speed may be generic and preselected, e.g. a single feeding speed suitable for bank notes 10 of different origin and condition may be used always. However, the feeding speed may also be specific to the bank note 10 approaching the brushed roller 2, e.g. a detector signal may indicate that the approaching bank note 10 is of a specific type, requiring a specific feeding speed.

[0137] In one embodiment the method additionally allows the bank note 10 to be directed along a second path G by controlling the first note feeder 11, the brushed roller 2, and the second note feeder 12. When a second path selection signal is received 102, the second path selection signal indicating a desired bank note 10 movement along the second path G from the second note feeder 12 via the brushed roller 2 to the first note feeder 11, the first note feeder 11 may be set 104, the brushed roller 2 may be set 106, and the second note feeder 12 may be set 108. Setting the first 104 and second 108 note feeder and the brushed roller 106 may be done in analogy to their setting in response to the first path selection signal but with the bank note 10 moving along a second path G which has the opposite direction of the first path F. The feeding direction of the first 11 and second 12 note feeder in response to the second path selection signal may be opposite to the feeding direction of the first 11 and second 12 note feeder in response to the first path selection signal. The rotational direction of the brushed roller 2 in response to the second path selection signal may be opposite to the rotational direction of the brushed roller 2 in response to the first path selection signal.

[0138] In one embodiment the method additionally allows the bank note 10 to be directed along a third H and a fourth I path by setting 110 a third note feeder 13 in addition to setting 104 the first note feeder 11, setting 106 the brushed roller 2, and setting 108 the second note feeder 12. A third path selection signal may indicate a desired bank note 10 movement along the third path H from the first note feeder 11 via the brushed roller 2 to the third note feeder 13. A fourth path selection signal may indicate a desired bank note 10 movement along the fourth path I from the third note feeder 13 via the brushed roller 2 to the first note feeder 11. The setting of the first 11 and third 13 note feeders and the brushed roller 2 in response to the third or fourth path selection signal may be conducted analogously to the setting of the first 11 and second 12 note feeders and the brushed roller 2 in response to the first or second path selection signal.

[0139] It should be understood that whenever a path selection signal is received the note feeders and the brushed roller involved in the path may be set either simultaneously or sequentially. The timing of setting the note feeders and the brushed roller may be such that the movement direction and speed of each component has reached its set value before the leading edge 14 of the bank note 10 reaches the component in question. The timing of setting the note feeders and the brushed roller 2 may also be such that whenever two note feeders are feeding the bank note 10 the note feeders have the same feeding speed.

[0140] In the above the inventive concept has mainly been described with reference to a limited number of examples. However, as is readily appreciated by a person skilled in the art, other examples than the ones disclosed above are equally possible within the scope of the inventive concept, as defined by the appended claims.
