Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a banknote conveying device in a banknote handling device.

(b) Prior art As such a banknote conveying device, for example, the Jikkosho
As shown in Japanese Patent No. 57-47879, banknotes are generally conveyed by a belt stretched between a pair of pulleys. However, in this method, if the distance between the pulleys becomes long, the belt may meander, resulting in inaccurate conveyance and the bill becoming bent or jammed. Therefore, there is a method of correcting the movement of the belt by installing an idler roller between the pulleys as disclosed in Japanese Utility Model Publication No. 57-7090, but even in this case, the idler roller is perpendicular to the direction of movement of the banknote. If the belt is tilted in that direction, the belt will meander or come off. That is, FIG. 4 shows the relationship between the idler roller 3 and the belt 2 as seen from the moving direction of the endless belt 2. When the idler roller 3 is tilted in the direction of the arrow perpendicular to the moving direction, the cylindrical idler Since the contact surface of the roller 3 with the belt 2 is oblique, the contact area becomes small, and the belt 2, which should originally be at the position indicated by the dotted line, moves and easily comes off the idler roller 3.

(c) Problems to be Solved by the Invention As described above, in the conventional bill conveying device, the belt may come off due to meandering of the belt or the inclination of the idler roller, causing problems in conveying bills.

In view of the above points, the present invention provides a banknote handling device that can stably carry out banknote conveyance operations.

(d) Means for solving the problem The present invention includes an idler roller that rotates in contact with the belt between a pair of pulleys on which a banknote conveying belt is stretched, and an idler roller on one side of the idler roller. A locking member for locking the belt is provided, and an inclined portion for guiding the belt to the locking plate is formed on the surface of the idler roller that comes into contact with the belt.

(e) Effect With the above configuration, the belt during the conveyance operation is driven by being brought to a locking member provided on one side of the idler roller by the inclined portion.

(F) Embodiment FIG. 1 shows the configuration of a banknote processing apparatus equipped with a banknote conveyance device 5 according to the present invention. When a banknote is inserted through the insertion slot 6 and the sensor 7 outputs a detection signal, the rollers 8A and 8B rotate and the belt 9 takes in the banknote. The bill taken in by the belt 9 passes through an identification sensor 10, and an identification circuit (not shown) determines the suitability of the bill based on the detection signal of the sensor 10. If the banknote is invalid, the identification circuit controls the rollers 8A, 8B to reverse and return the banknote. On the other hand, if the bill is appropriate, the bill is introduced into the bill conveying device 5 and continuously transferred, and then stored in the bill storage section 11. The bill conveyance device 5 has an endless belt 2 stretched around a pair of pulleys 1A and 1B, and an idler roller 3 that contacts the belt 2 and rotates about a shaft 12 is arranged between the pulleys 1A and 1B. . Idler roller 3 is
It is attached to one end of a swinging member 13 rotatably supported on a shaft 22, and a spring 1 is attached to the other end of the swinging member 13.
4 is attached to urge the idler roller 3 toward the belt 2. The idler roller 3 is provided with a locking member 4 on one side as shown in FIG.
An inclined portion 3A that is inclined toward the locking member 4 is formed on the contact surface with the locking member 4. Therefore, the idler roller 3 according to the present invention has a conical shape such that the area of a cross-sectional circle cut in the banknote transfer direction becomes smaller as it approaches the locking member 4. Banknote storage section 11
1 is for stacking banknotes in a space between a guide wall 14 having an opening 13 and a bottom plate 15, in which banknotes 16 are stored in a partition plate 1 which is biased by a spring 17.
8 and is pressed and held toward the guide wall 14 side.
The bill moves on the guide wall 14 by the drive of the belt 2, and stops moving when it reaches the opening 13. By moving the stack plate 19 toward the opening 13 against the spring 17, the bill is moved. It is designed to be pushed into the banknote storage section 11.

With the above configuration, the belt 2 is guided by the inclined portion 3A of the idler roller 3, so that it comes into contact with the locking member 4 and moves. Therefore, since the belt 2 always moves on the same trajectory, meandering of the belt 2 is prevented and banknotes can be stably transferred. Furthermore, the idler roller 3 may be tilted as shown in FIG. For example, when pushing banknotes 21 into the banknote storage section 11 using the stack plate 19, the banknotes 21 are moving in close contact with the belt 2, and when the stack plate 19 performs a pushing operation, the belt 2 is pulled by the banknotes 21. , thereby idler roller 3
slopes inward. However, since the idler roller 3 is formed to be thicker in the direction away from the locking member 4, even if the idler roller 3 is pulled by the banknote 21 and tilts inward, the sloped portion 3A will not reach the belt as shown in FIG. Since it is in the same state as the contact surface of belt 2, that is, in a substantially horizontal state, the adhesion with belt 2 is not lost. Therefore, even if the idler roller 3 is tilted, the contact surface of the belt 2 with the inclined portion 3A will not become smaller, and the belt 2 will be prevented from being largely displaced from the idler roller 3 and will not come off.
In order to further ensure that the belt 2 is removed from the idler roller 3, a locking plate 4A is also provided on the inner side of the idler roller 3. This locking plate 4A is provided with a wall 20 whose peripheral edge protrudes from the idler roller 3, and the height t of the wall 20 is smaller than the thickness of the belt 2.

(g) Effects of the invention According to the invention, a locking member is provided on one side of the idler roller, and an inclined portion is provided on the contact surface with the belt to guide the belt to the locking member. The banknotes can be moved along a fixed trajectory, making the banknote conveyance operation stable. Even if the idler roller is tilted in the other direction, the belt will not come off the idler roller because the inclined portion makes it difficult for the belt to move in the same direction.
