• the note transport unit 1 can be carried with a handle 3 while e.g. transported within a note handling system (not shown).
• Inside the housing 2 there is inter alia a note storage drum 5, on which input notes can be stored by being spooled around a central hub, between first and second film layers 8a and 8b provided by film drums 9a and 9b.
• the note storage drum 5 has a first and a second side wall 6a and 6b, respectively, rotateable around a central axis of the note storage drum 5, for spooling the first and second films 8a and 8b around the central hub when rotating in a first direction, and for spooling off the first and second films 8a and 8b when rotating in a second opposite direction.
• Note drum motor 7 is arranged to drive the note storage drum 5
• film drum motors 10a and 10b are arranged to drive the film drums 9a and 9b, respectively, when the note transport unit 1 is connected to e.g. a note handling unit for receiving or dispensing operations.
• the note transport unit 1 further has a note coloring system 11 comprising inter alia ink containers 12 and a cartridge 13.
• the ink containers 12 can provide their ink content into the first side wall 6a.
• Ink triggering parameters which may be detected by the sensor can for instance be temperature, pressure, linear momentum, fluid etc.
• the note coloring system 11 may at unauthorized access receive an ink triggering signal from a processor coupled to the sensor and in response thereto provide a high pressure gas injection via the cartridge 13, triggering the injection of ink from the ink containers 12 into the first side wall 6a via a nozzle 14.
• the nozzle 14 provides ink into the first side wall 6a, in which ink distribution grooves are arranged, via an opening 19 (see Fig. 3) in the first side wall 6a, the opening being 19 located around the central axis of the note storage drum 5.
• the ink is subsequently distributed inside the first side wall 6a, whereby ink is injected from ink outlet openings 16 of the first side wall 6a, in between the first and second side walls 6a and 6b, dyeing notes stored between first and second layers of film 8a and 8b spooled onto the drum.
• the ink outlet openings 16 are so distributed along the surface of an inner side 21 (see Fig. 4) of the first side wall 6a facing the second side wall 6b as to provide ink circumferentially between any layer of first and second films 8a and 8b spooled on the note storage drum 5.
• the ink reaching the first and second films 8a and 8b may have a high speed and being relatively cohesive due to the short distance for the ink to travel from the ink outlet openings 16 to the first and second films 8a and 8b spooled onto the note storage drum 5.
• the effect of more ink penetrating deeper between the layers of film may be achievable compared to if ink outlet openings 16 would have been positioned farther away from the films.
• ink dyeing of the notes may be enhanced, i.e.
• FIG. 2 shows another perspective view with parts broken away of the note transport unit 1 in Fig. 1. More specifically, in this illustrative example, the inner side 21 of the first side wall 6a is shown, on which a plurality of the ink outlet openings 16 can be seen. The ink outlet openings 16 are facing towards the second side wall 6b. Thereby notes stored between the first and second films 8a and 8b spooled on the central hub 15 may efficiently be ink dyed upon unauthorized access to the notes.
• the first side wall 6a having the ink outlet openings 16 can be rotateable around the central axis of the note storage drum 5. Each ink outlet opening 16 may thus be seen as orbiting around the central axis of the note storage drum 5 when the first side wall is rotating, i.e. when the note storage drum 5 is rotating.
• Fig. 3 shows a side view of the side wall 6a of the note storage drum 5 according to the invention.
• the first side wall is shown without its cover plate, whereby an intermediate side 21 can be seen, with an opening 19 extending through the side wall 6a, around its central axis, which is also the central axis of the note storage drum 5.
• the nozzle 14 is introduced into opening 19, as shown in Fig. 1.
• the first side wall 6a further comprises first radially extending ink grooves 20, for distributing ink provided centrally into the opening 19 by the nozzle 14, to a peripherally extending groove 17.

• This distribution of the ink can allow further distribution of the ink to a plurality of at least partly radially extending ink distribution grooves 18, each of which is connected with a plurality of ink outlet openings 16.
• the ink outlet openings 16 can be evenly distributed along each of the at least partly radially extending ink distribution grooves 18.
• the peripherally extending groove can also comprise ink outlet openings 16.
• the flow direction of ink may in one embodiment be radially outwards when having been provided centrally by the nozzle 14 into the first side wall 6a, followed by peripheral flow directions for further distribution of the ink to thereafter flow radially inwards for feeding the ink at high pressure through the ink outlet openings 16 of the at least partly radially extending grooves 18 for ink dyeing of notes between the first and second films 8a and 8b.
• the at least partly radially inwards extending grooves 18 can end at a distance d from the central axis of the note storage drum 5, thereby enabling higher pressure for the ink leaving the ink outlet openings 16.
• the distance d may in one embodiment be substantially equal to the radius of the central hub 15.
• the peripherally extending distribution groove 17 can be positioned at a distance D from the central axis of the note storage drum 5.

• the first side wall 6a can comprise gears along its circumference, which, when the first side wall 6a is arranged in the note transport unit 1, can be coupled to gears of the note drum motor 7 (see Fig. 1), thus forming part of the rotateable note storage drum 5.
• the inventive note transport unit 1 may thus provide efficient ink dyeing of notes stored between films 8a and 8b on the rotateable drum therein.
• the at least partly radially extending distribution grooves 18 are in fact radially extending, however, the at least partly radially extending distribution grooves 18 may, within the scope of the invention, also be at least partly radially extending.

• the short distance between the first side wall 6a and the notes N1-N3 stored on the note storage drum 5, may enable the ink I to penetrate sufficiently deep between each layer of the first and second films 8a and 8b spooled onto the note storage drum 5 and thereby ruining the notes stored thereon.
• Fig. 6 shows a flowchart illustrating a method of ink dyeing notes in the note transport unit in Fig. 1.
• the following steps may be carried out in the note transport unit 1:
