Abstract

PURPOSE:To prevent a shutter opening/closing a paper money transportation path from moving by means of external force by constituting a gear transmission means with a worm gear fixed to the driving shaft of a motor and a worm wheel engaged with the worm gear. CONSTITUTION:A shutter means 60 consists of the worm gear 62 where the gear transmission means 61 transmitting the driving force of a shutter motor 57 is fixed to the driving shaft 57a of the shutter motor 57 and of the worm wheel 63 engaged with the worm gear. Since the shutter 54 opening/closing the paper money transportation path is driven by the motor 57 through the gear transmission means 61, a deceleration ratio viewed from a motor 57-side is large, friction force between the engaged gears is large and a gear deceleration device is laid. Even if the shutter is pushed up from a state where the paper money transportation path is blocked by external force, the motor 57 does not follow up and rotate, and the shutter 54 does not move up.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill processing apparatus used in automatic vending machines, currency exchange machines, pachinko ball lending machines, metal lending machines, and the like.

[0002]

2. Description of the Related Art Generally, in a main body of a vending machine or the like that handles banknotes, it is possible to discriminate the authenticity of the inserted banknotes and to store only the banknotes regarded as genuine banknotes. Is installed.

This banknote handling apparatus is roughly classified into a banknote transport path which is connected to a banknote insertion slot and guides the banknotes inserted from the banknote insertion slot into the main body of the apparatus, and the authenticity of the banknotes transported. It is composed of a bill discriminating means and a bill accommodating means for pushing bills regarded as genuine bills into the stacker and sequentially accumulating them.

On the other hand, the applicant of the present invention previously filed Japanese Patent Application No. 5-276.
In No. 592, in order to prevent the banknotes once inserted from the banknote slot from being forcibly pulled out from the banknote slot, the banknotes are connected to the banknote slot by a driving force of a motor. A proposal was made that a shutter means for forcibly opening and closing the conveying path was provided, and the shutter means closed the banknote conveying path after passing the inserted banknotes to prevent the banknotes from being forcibly pulled out from the banknote slot. .

FIG. 3 is a conceptual front view showing the shutter means 32 of the bill processing apparatus previously proposed by the applicant of the present application.

The shutter means 32 is a first plate 50 fixed to a front mask (which will be described later) having a bill insertion slot, and is vertically slid with respect to the first plate 50 via a rack and pinion mechanism 51. It is composed of a freely supported second plate 52, and is planted at a lower end 52a of this second plate 52 in a staggered manner with alternate postures as shown in FIG. 4 shown in the bottom view. A shutter 54 including a plurality of plates 53 is arranged.

Of the plurality of plates 53, the plate 53a planted in the center has a substantially V-shaped cross section, and the others have a substantially rectangular cross section.

Further, since the shutter 54 composed of the plurality of plates 53 is planted in such a manner that the postures thereof are alternately changed, when viewed from the front as shown in FIG. The whole area is covered with almost no space.

On the other hand, as shown in FIG.
Upper and lower chutes 5 that form a banknote transport path at a position facing each other
The plurality of plates 5 and 56 are arranged so that the plurality of plates 53 forming the shutter 54 can be projected and retracted.
A plurality of holes 55a, 5 having a shape corresponding to the cross-sectional shape of FIG.
6a is formed.

According to the shutter means 32 described above, as shown in FIG. 6 which is a sectional view of the main part of the front mask 22, the inside of the banknote transport path 27 is expanded to allow the inserted banknote A to be inserted in the direction B. In this case, the second plate 52 is moved upward by a predetermined distance by a rack and pinion mechanism 51 including a pinion 57a formed of a spur gear of the shutter motor 57 and a rack 52b formed on the second plate 52 that meshes with the pinion 57a. The plurality of plates 53 constituting the shutter 54 at the lower end of the second plate 52 are pulled out from the holes 56a formed in the lower chute 56, and the bill transport path 27 formed between the upper and lower chutes 55, 56 is expanded. Open.

On the other hand, after passing the inserted bill A, the bill conveying path 2
7 is closed, as shown in FIG. 7, the driving force of the shutter motor 57 pulls the second plate 52 downward by a predetermined distance via the rack and pinion mechanism 51, whereby the shutter 54 at the lower end of the second plate 52 is pulled down. A plurality of plates 53 constituting the hole 5 formed in the lower chute 56
The banknote transport path 27 formed between the upper and lower chutes 55 and 56 is closed by being inserted into the 6a.

When the banknote transport path 27 is closed by the shutter 54 as shown in FIG. 7, even if the inserted banknote A is forcibly pulled out in the direction of arrow C, the entire area in the widthwise direction of the banknote transport path 27 is covered by a plurality of plates 53. Since it is blocked by, the inserted bill A can be forcibly withdrawn.

[0013]

By the way, according to the above-mentioned shutter means 32, the driving force of the shutter motor 57 is transmitted to the second plate 52 via the rack and pinion mechanism 51 as shown in FIG. The second plate 52 is pulled down by a predetermined distance, and the vertical chutes 55, 56
Although the banknote transport path 27 formed between the racks and the pinion mechanism 51 is closed, the second plate 52 has a small reduction ratio when viewed from the motor 57 side and a small frictional force between the meshed gears. Since it is connected to the shutter motor 57 via the shutter motor 57, if the second plate 52 is forcibly pushed upward from the state in which the banknote transport path 27 is closed, the motor 57 follows and rotates, so that the second plate 52 moves upward. There is a risk that the bill transport path 27 may be opened and the bill transport path 27 may be expanded.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a bill processing apparatus in which a shutter that opens and closes a bill transport path does not move due to an external force.

[0015]

In order to solve the above-mentioned problems, according to the present invention, a banknote conveying path connected to a banknote slot is opened and closed by a shutter, and the shutter is driven by a motor via gear transmission means. In the bill processing apparatus configured as described above, the gear transmission means is composed of a worm gear fixed to the drive shaft of the motor and a worm wheel meshing with the worm gear.

[0016]

According to the above-described bill processing apparatus, the shutter for opening and closing the bill transport path is driven by the motor through the gear transmission means including the worm gear fixed to the drive shaft of the motor and the worm wheel meshing with the worm gear. Therefore, a gear reduction device with a large reduction ratio seen from the motor side and a large frictional force between gears that mesh with each other is interposed, so that the shutter conversely closes the bill conveyance path by an external force. Even if an attempt is made to push it up from above, the motor does not follow and rotate, and therefore the shutter does not move upward.

The above-mentioned first spur gear 64 meshes with the second spur gear 66 disposed below the worm wheel 63, and further, the third spur gear 66 is coaxial with the second spur gear 66. The spur gear 67 is fixed. This third spur gear 6
7 and the second spur gear 66 through the shaft 68 to the first plate 50
It is rotatably supported by.

On the other hand, a rack 69 is fixed to the second plate 52 constituting the shutter 54, and the third spur gear 67 meshes with the rack 69.

According to the gear transmission means 61 having the above-mentioned structure, when the shutter motor 57 rotates in one direction as shown in FIG. 2, the driving force thereof is the worm gear 62, the worm wheel 63, the first spur gear 64, and the second spur gear 64. Spur gear 66, third
The second plate 5 via the spur gear 67 and the rack 69.
2, and as a result, the second plate 52 is pulled upward by a predetermined distance, widens the banknote transport path 27 shown in FIG. 6, and allows the inserted banknote A inserted in the direction of arrow B to pass.

On the other hand, the shutter motor 57 rotates in the other direction, and the driving force of the shutter motor 57 is the same as the above-mentioned path, and the gear transmission 6
When it is transmitted to the second plate 52 via 1, the second plate 52 is pulled down by a predetermined distance and closes the banknote transport path 27 as shown in FIG. 7, thereby resisting the force acting in the arrow C direction. To prevent the inserted bill A from being pulled out.

On the other hand, according to the shutter means 60 having the above-mentioned gear transmission means 61, as shown in FIG. 1, the second plate 52 is forcibly forced from the state in which the bill conveying path is closed.
When a force in the direction of arrow D is applied from the outside in order to push the upper part upward, a gap between the motor 57 and the second plate 52 shown in FIG.
As shown in FIG. 5, a gear reduction mechanism including a worm gear 62 and a worm wheel 63 having a large reduction ratio and a large frictional force between gears meshing with each other when viewed from the motor 57 side is interposed, so that the bill conveyance path is closed. Even if an attempt is made to push up the second plate 52 from above, the force is not transmitted as a large gear resistance between the worm gear 62 and the worm wheel 63, and therefore the motor 57 does not follow and rotate. 54 will not move upward.

Therefore, since the second plate 52 constituting the shutter 54 does not move upward due to the external force, the banknote transport path 27 is expanded by the external force after the banknote transport path 27 is closed by the shutter 54. Therefore, it is possible to further improve the effect of forcibly pulling out the inserted bill A.

[0027]

As described above, in the bill processing apparatus of the present invention, a gear including the worm gear having the shutter for opening and closing the bill transport path fixed to the drive shaft of the shutter motor and the worm wheel meshing with the worm gear. Since it is driven via the transmission means, the gear transmission means, which has a large reduction ratio and a large frictional force between the meshing gears when viewed from the motor side, is intervened. Even if the shutter is forcibly pushed upward from the state where the road is blocked, the gear transmission means becomes a great resistance and the motor does not follow and rotate, so the movement of the shutter is blocked as much as possible and the inserted bills. It is possible to further improve the effect of preventing the pulling out.
