Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a banknote holding device used in a vending machine, a money changer, or the like.

(B) Prior Art Generally, it is desired that banknote holding devices used in automatic vending machines, currency exchange machines, etc. be as small and thin as possible. However, as shown in Japanese Utility Model Publication No. 55-27632, this type of banknote holding device has a large gap between the lower surface of the pressing piston and a holding member that guides and holds the banknotes transferred by the conveyance means. Since the device is constructed so that banknotes from the device can be easily introduced onto the holding member, the device has the disadvantage of being large in size.
In addition, as shown in FIG. 8, in this type of device, as the number of banknotes T held between the guide rail 40 and the holding plate 41 increases, an opening is formed in the center between the guide rails 40. Since it is bent and protrudes in the direction of the opening 42, there is a drawback that it obstructs the introduction of the banknote _T1 transferred onto the guide rail 40. This drawback can be overcome by making the thickness of the guide rail 40 larger than the deflection dimension of the bill T, but in this case, the device would be thick and large.

(c) Object of the Invention In view of the above, the present invention provides a thin banknote holding device that does not obstruct the introduction of banknotes onto the guide rail.

(d) Structure of the Invention The present invention provides a pair of conveyor belts that transport banknotes that have been determined to be appropriate by contacting both ends of the banknotes so as to reach a predetermined position, and a pair of conveyor belts provided corresponding to each of the conveyor belts. a guide rail, a holding box located corresponding to the guide rail and provided on the opposite side of the conveyor belt across the guide rail, and a banknote transferred to a predetermined position by the conveyor belt while being guided by the guide rail. A stack plate that is pushed into the holding box through an opening formed between the guide rails, and a stack plate that receives the banknotes pushed in by the stack plate and is attached so that the ends of the banknotes are held between the guide rails. A pressing member is provided between the pair of conveyor belts, the pressing member is inclined in the direction of transporting the banknotes and protrudes in the opposite direction to the opening, after the banknotes are stored in the holding box. provided corresponding to the ends, so that the intermediate portion between both ends of the banknotes transferred by the conveyor belt is bent in the opposite direction to the opening at a position corresponding to the rear end of the banknotes stored in the holding warehouse. It is composed of

(E) Embodiment FIGS. 1 and 2 show a side sectional view and a front sectional view, respectively, of a bill holding device according to the present invention.
Reference numeral 1 denotes a banknote identification unit that determines whether the banknotes inserted through the insertion slot are appropriate while being conveyed by the belt 2 and conveys the banknotes that have been determined to be appropriate to the banknote holding device 3 . 4 and 4' are drive shafts 6 that are linked to the deceleration motor 5.
A conveyor belt 9, 9' is stretched between pulleys 8, 8' mounted on the driven shaft 7. 10 is a guide plate having a pair of guide rails 10a, 10b provided corresponding to the conveyor belts 9, 9', and an opening 11 slightly smaller than the size of one banknote is provided between the guide rails 10a, 10b. The banknotes are formed to support the ends of banknotes that are transported together with the conveyor belts 9, 9'. 12 is the guide rail 10
a, 10b, and is provided opposite to the conveyor belts 9, 9', and is provided with a holding plate 14 that is biased toward the guide rails 10a, 10b by a spring 13, and the guide rail 10a , 10b, and hold the banknotes T between them. Holding plate 14
is attached and supported together with a spring 13 to a storage door 16 whose lower part is pivoted to a housing 15 so that it can be opened and closed rearward, and by opening the storage door 16, the banknote storage 12 can be opened. I can do it. Reference numeral 17 denotes a stack plate provided with a slidable guide portion 19 that fits into a guide pin 18 fixed to the housing 15, and is positioned corresponding to the opening 11, and extends through the opening 11 to the storage storage 12 side. It is installed so that it can move freely forward and backward.
Normally, the elasticity of the spring 20 urges it in a direction away from the banknote storage 12 side and holds it in a retreated state. Stack cams 21a and 21b move the stack plate 17 into the holding warehouse 12 against the elasticity of the spring 20, and are fixed to a drive shaft 23 and a driven shaft 24, respectively, which are connected to a deceleration motor 22. The drive shaft 23 and the driven shaft 24 are connected to pulleys 25 and 26.
A belt 27 is stretched between the pair of pulleys 25 and 26 so that they interlock. With one rotation of the stack cams 21a, 21b in the counterclockwise direction in FIG. The banknotes whose ends are clamped are pushed into a banknote storage 12 through an opening 11. 2
Reference numeral 8 denotes a pressing member provided at the upper part between the conveyor belts 9 and 9', which is formed so as to be inclined toward the banknote transfer direction and protrude in the opposite direction to the opening 11, and whose lower part is connected to the holding box 12. Banknotes T stored inside
It is located near the upper end of the banknote, which is the rear end.

The operation of the above configuration will be explained. When the tip of the banknote T that has been determined to be appropriate reaches the sensor 29 consisting of a set of LEDs and a phototransistor, the deceleration motor 5 is driven, and the banknote T is moved between the conveyor belt 9 and the guide plate 1.
0. Then, the banknote T is transferred while being bent in the opposite direction to the opening 11 by the pressing member 28 at the intermediate portion between the two ends supported by the guide rails 10a and 10b. Therefore, as shown in FIG.
Banknotes being transferred, even if they protrude in the direction
The leading end of T ₁ is transferred without being stopped by the upper end, which is the rear end of the banknote T stored therein. When the rear end of the banknote T ₁ passes through a sensor 30 consisting of a set of LEDs and a phototransistor, the deceleration motor 5
is stopped, and the banknote _T1 is transferred and stopped at a predetermined position. On the other hand, when the deceleration motor 5 is stopped, the deceleration motor 22 is driven, and the operation of pushing the banknotes into the holding warehouse 12 is started. In the standby state shown in FIG. 4, the stack plate 17 has withdrawn from the opening 11. The stack cam 2 is driven by the deceleration motor 22.
When the stack plate 17 is pressed in the direction of the opening 11 by the rotation of the stack plates 1a and 21b, the stack plate 17 advances into the holding warehouse 12 through the opening 11 and springs up. Bill T against 13
Push in. And stack cams 21a, 21b
When the cam 31 fixed to the driven shaft 24 and the position detection switch 32 confirm that the motor has made one rotation and returned to the standby position, the deceleration motor 22 is stopped.

(F) Effects of the Invention Since the present invention is configured as described above, even if the banknotes stored in the holding warehouse are bent, the transferred banknotes will not be stopped by the bending. Transfer can be carried out reliably. Furthermore, the thickness of the guide rail can be reduced, and a thin and small banknote holding device can be provided.
