Describe for effect according to the depositing bank paper let-off gear(stand) of above-mentioned formation.

In addition, the below action of Shuo Ming each one is based on that the program (software) that is stored in not shown storage part controls by not shown control part.

Fig. 4 is that expression has used the bank note (medium) of the impeller mechanism of present embodiment to pile up the lateral plan of let-off gear(stand), (a) is the state when deriving, the state when (b) being depositing bank paper.

At first, when deriving bank note 10, be fixed in the detected portion 7a of the position detection component 7 of rotating shaft shown in Figure 14, at the impeller 1 that stops to drive by position-detection sensor 8 detected positions, the impeller 1 that drives and blade 1a, the 2a of slave end impeller 2, shown in Fig. 4 (a) with the periphery that is positioned at rotating shaft 4 almost half scope and do not enter the mode of carrying road 18 and keep out of the way.

Bench board 12 is risen, behind uppermost bank note on the bench board 12 10 and selection roller 14 butts, when feed roller 13 being rotated along clockwise direction by not shown electrical motor, then the rotation of feed roller 13 is passed to selection roller 14 by rotating band 16, because selection roller 14 is rotated in a clockwise direction, so feed roller 13 is derived and be sent to bank note 1 from bank note containing portion 11.

At this moment, because the rotation that mono-directional overrun clutch 6 does not transmit above-mentioned electrical motor to the rotating shaft 4 that drive side impeller 1 and slave end impeller 2 and reverse roll 17 are installed, thereby drive side impeller 1 and slave end impeller 2 and reverse roll 17 do not rotate, so blade 1a, the 2a of drive side impeller 1 and slave end impeller 2 keep keeping out of the way state.

Therefore, bank note 10 is sent to conveying road 18 by the rotation of feed roller 13, and is carried by not shown supply unit.

When piling up bank note, bench board 12 detecting sensor 21 in the above detects the position standby of uppermost bank note 10, and passes through not shown electrical motor feed roller 13 is rotated in the counterclockwise direction.

At this moment, because rotation to the above-mentioned electrical motor of rotating shaft 4 transmission that drive side impeller 1 and slave end impeller 2 and reverse roll 17 have been installed, thereby drive side impeller 1 and reverse roll 17 are rotated in a clockwise direction, therefore pass through the rotation of this drive side impeller 1, then as in Fig. 3 explanation, blade 1a, the 2a of drive side impeller 1 and slave end impeller 2 crosses over launching radially in full week of rotating shaft 4.

And because the protruding 1b of drive side impeller 1 collides with the protruding 2b of slave end impeller 2 and engages, therefore slave end impeller 2 also rotates with drive side impeller 1 shown in Fig. 4 (b).

In this state, when bank note 10 was transferred road 18 conveyings, this bank note that transports 10 is fed roller 13 and reverse roll 17 is seized on both sides by the arms, and be admitted in the bank note containing portion 11 by the rotation of feed roller 13 and reverse roll 17.

And, be admitted to the bank note 10 in the bank note containing portion 11, collide bottom drg 20 and stop and falling, yet the rear end of bank note 10 is shown in Fig. 4 (b) at this moment, the blade 1a, the 2a that are driven lateral lobe wheel 1 and slave end impeller 2 pat, be pressed on the bank note 10 on the bench board 12, thus can be in the mode of the accumulation that do not hinder follow-up bank note 10 and arrange.

When pile up finishing, in the position of the detected parts 7a of the position detection component 7 that utilizes position-detection sensor 8 to detect to be fixed in rotating shaft 4, so that the mode that the drive side impeller stops and stopping electrical motor.

Go into thus Fig. 3 explanation like that, slave end impeller 2 is rotated in a clockwise direction by deadweight, blade 1a, the 2a of drive side impeller 1 and slave end impeller 2 is positioned at almost half scope of the periphery of rotating shaft 4, and carries the mode in the road 18 and keep out of the way not enter.

In addition, consider after the accumulation processing of bank note 10 finishes that therefore the situation that also exists the slave end impeller not rotate because of deadweight increases following processing under these circumstances.

Fig. 6 is the lateral plan of expression with the example of the situation of slave end impeller 2 pressure rotations.

After the accumulation processing of bank note 10 finishes, under the situation that slave end impeller 2 does not rotate because of deadweight, shown in Fig. 6 (a), because the blade 2a of slave end impeller 2 is in the state of carrying in road 18 and the bank note containing portion 11 that enters, therefore before the accumulation processing of bank note 10 finishes the back or derives processing, shown in Fig. 6 (b) by bench board 12 is risen, end with the bank note 14 piled up on the end of bench board 12 or the bench board 12, be pressed into after the blade 2a that enters the slave end impeller 2 in the bank note containing portion 11, bench board 12 is descended.

Make its rotation forcibly owing to apply rotational force thus to the slave end impeller, therefore the blade 2a of slave end impeller 2 is also same with the blade 1a of drive side impeller 1, be positioned at almost half scope of the periphery of rotating shaft 4, and carry the mode in the road 18 and keep out of the way not enter.

So by before the accumulation processing end back or derivation processing of bank note 10, increase is with the processing of bench board 12 liftings, even therefore after the accumulation processing of bank note 10 finishes, under the situation that slave end impeller 2 does not rotate because of deadweight, also can make 2 rotations of slave end impeller forcibly, thereby blade 2a is kept out of the way reliably not enter the mode of carrying in the road 18.

Impeller mechanism according to the embodiment of above explanation, owing to constitute impeller with drive side impeller and slave end impeller, therefore in the device that the derivation of carrying out medium is piled up, under the situation about using as the impeller mechanism of the rear end of patting accumulation volume medium, because the rotation of a drive side impeller and slave end impeller, the blade that just can make two impellers is in the mode of the derivation that do not hinder medium and keep out of the way, and, therefore can obtain the effect that just can realize at an easy rate with simple formation owing to need not to be used to make definite-purpose motor that impeller keeps out of the way and chain etc.

In addition, owing to be to constitute impeller with drive side impeller and slave end impeller, when making the rotation of drive side impeller, the blade of drive side impeller and slave end impeller is to cross over launching radially in full week of rotating shaft, therefore be not subject to material, thickness and the temperature traverse of rotative speed or blade and through the influence of annual variation etc., the effect of the action that acquisition can all-the-time stable.

In addition, the present invention is not limited to the above embodiments.

For example, the above embodiments are to make a slave end impeller 2 and drive side impeller 1 combination, yet also can make two slave end impellers 2 and drive side impeller 1 combination.

In addition, in the above embodiments, engage with the protruding 2b of slave end impeller 2 by the protruding 1b that makes drive side impeller 1, make slave end impeller 2 with 1 rotation of drive side impeller, yet also can be drive side impeller 1 when halted state has been rotated certain angle, make 2 rotations of slave end impeller again, and so long as when drive side impeller 1 stops, slave end impeller 2 can be by the engaging unit that rotate of deadweight, also can adopt the engaging unit of the combination etc. of protruding and groove.

In addition, it can also be following mode, promptly, make the rotating shaft 4 that is embedded in slave end impeller 2 barrel off centering and produce off-centre, perhaps by the mode that hammer is rotated reliably because of the deadweight of slave end impeller 2 is installed, by like this, before also the back can being finished in the accumulation processing of medium or deriving processing, omit the processing that makes worktable lifting.

In addition, impeller mechanism of the present invention is not limited to carry out the device of the accumulation and the derivation of bank note, also goes for handling the device of media such as bond, certificate, also goes for just carrying out the device of the accumulation of these media.
