It is assembled together with the fixed finger 15b into a bracket 24 attached to the longitudinally movable part 21 shown in FIG. 4 fb). This banknote alignment mechanism 23 includes a movable stopper 25 that is a first alignment member and a side alignment plate 2 that is a second alignment member.
The movable stoppers 25 are located facing the direction in which the banknotes 14 enter the gripping part 15 during the alignment operation, and the side alignment plates 26 are arranged so that the movable stoppers 25 face the direction in which the banknotes 14 enter the gripping section 15 during the alignment operation. The alignment members 25 and 26 serve to align the ends of the banknotes 14 from multiple directions (three directions in this example).
It is located in a position that is evacuated from 4, and is arranged so as not to interfere with the transfer of banknotes.

The drive mechanism for these alignment members 25 and 26 is constructed as follows. A base 25a of the movable stopper 25, which is a first alignment member, is connected to a support portion 24a on the bracket 24 via parallel links 27a and 27b, and a link 27b
The upper cam follower 28 is a movable stopper driving cam 29
is in contact with The cam follower 28 operates by following the rotation of the cam 29 by a spring guard (not shown).

The side alignment plate 26 is attached to the support part 24a so as to be able to swing around a fulcrum shaft 30 parallel to both sides of the banknote 14, and its lower end (cam follower 31,
11 is in contact with the side alignment plate drive cam 32.

The movable stopper 25 moves in parallel in the direction indicated by the outline arrow R. Since the cam crest of the movable stopper drive cam 29 is formed in two stages, the movable stopper 25 operates in two stages, and in the first stage of operation, the movable stopper 25 faces the direction in which the bill 14 enters the gripping portion 15 from the retracted position. It moves to a position and becomes a stopper that receives the banknotes 14, and in the second stage of operation it pushes the banknotes 14 together.

Further, as the side alignment plate driving cam 32 rotates, the side alignment plate 26 repeatedly swings in the direction shown by the outline arrow S via the cam follower 31, thereby pushing both sides of the banknote 14 together.

Two movable stoppers 25 facing the direction in which banknotes 14 enter
is operated in the same direction by two movable stopper drive cams 29 of the same shape, and the two side alignment plates 26 facing both sides of the banknote J4 are operated by two side alignment plate drive cams of the same shape. From the 32nd stage, they move in unison in opposite directions.

Next, the alignment operation during banknote transportation will be explained with reference to FIG.

As shown in FIG. 4A, the gripping section 15 that grabs and receives the unaligned bills 14 from the bill exit tray 7b of the appraisal/counting section 2 in a batch is rotated in the direction of the arrow.

At this time, the movable stopper 25 and the side alignment plate 26 are still in the retracted position. As shown in FIG.
When the movable stopper 25 rotates approximately 90 degrees, the movable stopper 25 operates one drive. Next, by opening the movable fingers 15a of the gripping section 15 which have turned in two directions and releasing the grip, the bill 1 is removed.
4 falls onto the movable stopper 25 in the first operating position, and the lower end of the banknote 14 is aligned with the movable stopper 25. At the same time, the side alignment plate 26 operates, and the banknotes 14
Align both sides. When both sides of the banknotes 14 are aligned, the movable stopper 2 is moved as shown in FIG.
