Further, when the guide 10 is manually rotated in the opposite direction to that described above, the latch piece 41 is rotated in the opposite direction to that described above by the locking piece 36, and is tilted to the position shown by the solid line 41 in FIG. The piece 36 and the latch piece 41 are engaged to prevent the guide 10 from rotating.

In this device, when a banknote is fed from the transport mechanism 1, the endless belts 8, 8 are driven in synchronization with the transport mechanism 1, and the banknote is transported either to the first transport mechanism 2 or to the second transport mechanism 3. do.

At this time, the pulling mechanism 4
6a is located between the endless belt 8.8 and the dry rollers 3a, 3a, so it acts as a guide for banknotes, and the pinch rollers 3b, 3b of the second conveyance mechanism 3 are separated from the drive rollers 3a, 3a. .

Therefore, the banknote is transported by the first transport mechanism 2 toward the second transport mechanism 3, and when passing through the sides 26a and 26a, the central part is bent by the protrusion 10a of the guide 10 as shown in FIG. Ru.

When the leading end of the bill comes into contact with the stopper 28, the leading end stops moving, and only the trailing end is further transported by the first transport mechanism 2.

In this case, in the illustrated example, the photo sensor 16 and the stopper 28
Since the interval is approximately the same as the length of the banknote in the conveying direction, the rear end of the banknote passes under the photo sensor 16 almost at the same time when the leading end contacts the stopper 28 .

However, if the interval is shorter than the length of the banknote, the trailing end of the banknote comes into contact with the stopper 28 and only the rear end side is transported by the first transport mechanism 2.
6, and if it is long, the tip will stop at the stopper 28.
The photo sensor 16 passes under the photo sensor 16 before coming into contact with the photo sensor 16 .

A banknote is held between the pinch rollers 3a and 3b, and then the second rotating mechanism described above operates and the picking mechanism 4 rotates once.

While the retrieval mechanism 4 is rotating, the rear end side of the banknote is
Although the banknotes are being transported by the transport mechanism 2 toward the second transport machine 3, almost the center side of the banknotes does not reach the roller 3at3.
b, and as the drag mechanism rotates 40 times, the bottom surface of the endless belt 6.6 and the drag mechanism 40
Since a space is created between them, the rear end of the banknote first bends downward, and then the rear end of the banknote comes off from the endless belts 8, 8, so that the rear end of the banknote hangs downward, and then the retrieval mechanism 4 By returning to the original position, the rear end side of the bill is bent along the curved portion of the guide 27.

When the retrieving mechanism 40 rotates, the endless belt 6.degree. 6 and the guide 10 prevent the rear end of the bill from bending upward.

When the retracting mechanism stops rotating 40 times, the solenoid lateral groove 23
The pinch rollers 3b, 3b are separated from the drive rollers 3a, 3a.

In this state, almost the front half of the bill is in the guide 2.
Since it is in contact with 7, it does not move.

After the retrieving mechanism 4 has rotated once, when the transport mechanism 1 also feeds the next banknote, the transport mechanisms 2, 3, retrieval mechanism 4, and solenoid mechanism 23 operate in the same manner as described above, and the first banknote (
The second banknote (the banknote fed next) is stacked on top of the banknote fed first.

Thereafter, each mechanism 2 each time a banknote is fed, whether it is the transport mechanism 1 or the transport mechanism 1.
, 3, 4, and 23 operate in the same manner and stack the banknotes in sequence,
Temporarily store it in that state.

In order to collect the banknotes stored in such a stacked state into the safe, the solenoid mechanisms 23 and 30 are energized to move the pinch rollers 3b and 3b to the drive rollers 3a and 3a.
K, the stopper 28 is moved below the guide 27, and then the second transport mechanism 3 and the transport mechanism 5'
T! :'Just rotate it in the normal direction.

In addition, when returning the temporarily stored banknotes, the solenoid mechanisms 23 and 30 are energized and the transport mechanisms 3 and 5 are operated until the rear end of the banknote reaches near the second transport mechanism 3 as described above. After normal rotation, the retracting mechanism 4 is first rotated through the plate body 26.
26 until the sides 26a, 26a reach the position shown by the two-dot chain line in FIG.
．． 2, 3, and 5 should be reversed.

In this way, the temporarily stored banknotes can be stored in the board 26,
26, the banknotes are conveyed from the second conveyance mechanism 3 toward the first conveyance mechanism 2, and further conveyed back to the bill insertion slot from the conveyance mechanism IK.

Note that the pinch rollers 3 b t 3 b are ejected toward the drive rollers 3 a, 3 a, and the pinch rollers 3 b t 3 b are ejected from the drive rollers 3 a, 3 a only from the time when the photo sensor 16 detects the leading edge of the banknote to the time when the trailing edge is detected. They may be spaced apart.

Note that the present invention is not limited to the above embodiments,
For example, when returning banknotes, instead of feeding the banknotes back toward the insertion slot, the banknotes may be fed to another return slot.

In addition, the present invention can be applied not only to banknote sorting devices such as automatic vending machines, but also to banknote sorting devices of other banknote handling devices such as automatic money changers that exchange high-value banknotes to low-value banknotes, and automatic teller machines. I can do it.

When the present invention is used in an automatic money changer, the &east conveying mechanism 1 may be used as a banknote sending device, and the aligned banknotes may be conveyed to a receiving slot by the conveying mechanism 5.

As described above, the present invention provides a pulling mechanism that deflects the trailing edge of the banknotes transported downward from the first transport mechanism using at least a pair of upper and lower endless belts to the second transport mechanism using a drive roller and pinch rollers. At the same time, a stopper is provided on the opposite side of the first conveyance mechanism with respect to the second conveyance means, and this stopper is made to protrude into the banknote conveyance path by the second conveyance means when the banknotes are aligned, and the pinch roller of the second conveyance mechanism is at least Since the banknotes are separated from the drive rollers when they are transported from the first transport mechanism to the second transport mechanism, it is possible to reliably stack the banknotes that are sequentially fed.
