The first feed roller 8 is provided on the outer surface of the gate roller 10.
Of the first feed roller 8 at the position corresponding to the recess of
A concave portion is provided at a position corresponding to the convex portion, and therefore the first feed roller 8 and the gate roller 10 do not contact each other, and sandwich the banknote 3 between them and convey it. 1
The first feed roller 8 and the gate roller 10 of the pair are
As shown in FIG. 2, it is provided at the center of the storage unit 2, that is, at a position where it contacts the center of the banknote 3.

The gate roller 10 is held via a one-way clutch at the tip of a gate holder 12 that rotates about a shaft 11 as a fulcrum, and is biased in a fixed direction by a spring 14. Therefore, the gate roller 10 separates the banknote 3 taken out from the storage section 2 by the pickup roller 19.

An adjusting screw 1 is provided at the lower end of the gate holder 12.
3 is provided, and the adjusting screw 13 is pressed against the fixing portion 32 by the spring 14. Therefore, by rotating the adjusting screw 13, the gate holder 12 can be rotated about the shaft 11 as a fulcrum, and the distance between the gate roller 10 and the first feed roller 8 or the overlap amount can be finely adjusted.

The banknote 3 is held by a pair of the first feed roller 8 and the gate roller 10 while being held therein.
Is fed out from the sheet, separated into one sheet by the gate roller 10 and conveyed to the second feed roller 15.

The structure and operation after the second feed roller 15 are the same as those of the conventional example shown in FIG.

Pickup roller 19 and sensor 26
The configuration and operation of are also the same as those of the conventional example of FIG.

A shaft 27 is provided above the belt 5, and an arm 28 is rotatably held on the shaft 24. Two rollers 30 (FIG. 2) are provided on the arm 28 and one end.
Are provided, and the two rollers 30 face the left and right positions of the rear end of the banknotes 3 stacked on the floor 4 of the storage section 2. A spring 29 is provided at the other end of the arm 28, and the roller 30 is pressed against the bill 3 by the force of the spring 29.

Next, the operation of the bill feeding device constructed as described above will be described.

When the floor 4 rises, the bills 3 mounted on the floor 4 come into contact with the pickup roller 19 and the roller 30 to pick up the pickup holder 20 and the arm 2.
8 is further raised while rotating 8, and the sensor 26 is stopped by being operated by a light shielding plate provided on the pickup holder 20.

When one bill 3 is fed out, the floor 4 rises and the sensor 26 operates to stop, and the next feeding operation is performed. In this feeding operation, the pressing force of the roller 30 is applied to all the bills below the highest bill until the end of the highest bill passes the line EE in FIG. When the uppermost banknote passes through the line E-E, the pressing force of the roller 30 is applied only to the second and subsequent banknotes and not to the uppermost banknote. Therefore, the frictional force between the second and subsequent banknotes is larger than the frictional force between the uppermost banknote and the second banknote, and the second and subsequent banknotes are dragged by the uppermost banknote and together. It is prevented from being paid out.

According to the results of the experiment, it is suitable that the pressing force of the roller 30 is 100 to 200 grams on the left and right respectively. If the pressing force is lower than that, there is no effect, and if it is higher than that, the resistance is too large and a pick miss occurs. Or skewing is likely to occur when the circulating bills are paid out.
