Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bill discriminating apparatus for discriminating whether a bill is a genuine bill or a fake bill.

[0002]

2. Description of the Related Art Conventionally, a bill discriminating apparatus of this type is known from Japanese Utility Model Publication No. 1-421010. In this bill identification device, a user inserts bills one by one into the bill identification device to identify the authenticity thereof, and an entrance for inserting a bill and an exit for inserting the bill inserted from the entrance. A transport mechanism for transporting the paper money to the entrance or returning it to the entrance, and a bill inspection mechanism having an optical sensor and a magnetic sensor for identifying the authenticity of the bill during the transportation by the transport mechanism. The transport mechanism is
A plurality of transport rollers, which are arranged at appropriate intervals in the transport direction of the banknotes and transport the banknotes sandwiched from above and below, and the banknotes that have passed through the banknote inspection mechanism, are sandwiched from the front and back to the exit. It is composed of a plurality of belts to be conveyed and a plurality of drive rollers for rotating these belts.

In this bill discriminating apparatus, the discrimination of bills from the authenticity and the subsequent conveyance are performed as follows. That is, first, when a bill is inserted into the entrance, the bill is conveyed toward the bill inspection mechanism by each conveying roller. When a bill passes through the bill inspection mechanism, the bill inspection mechanism identifies the authenticity of the bill. Then, when the bill is identified as a true bill, the bill is discharged from the exit to the outside while the transport direction of the bill is reversed by the belt of the transport mechanism. On the other hand, when the bill is identified as a fake bill, each transport roller rotates in the reverse direction to the rotation direction at the time of insertion of the bill, and returns the bill once stored in the device from the entrance to the outside. .

[0004]

In such a bill discriminating apparatus, when a bill is identified as a fake bill, as described above, each transport roller is rotated in the opposite direction to the insertion of the bill. At the time of rotation, the rotation speed of each transport roller and the timing of the rotation start, the slip between the transport roller and the bill, etc., cause wrinkles on the bill, and as a result, the bill may be jammed in the apparatus. is there. Further, in the above case, since the bill is returned to the outside from the entrance, the next bill cannot be inserted into the entrance unless the returned bill is once removed. For this reason, banknotes cannot be continuously applied to the banknote recognition device, and the efficiency of banknote recognition is extremely poor.

[0005] Of course, if the bill discriminating device is provided with an outlet for discharging a bill identified as a fake bill, in addition to an outlet for discharging a bill, the above problem can be solved. In this case, however, in this case, a mechanism for sorting the bills to the exit of the true bill or the exit of the fake bill must be provided in the bill transport path, which complicates the structure and increases the cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and can be manufactured at low cost, and can efficiently discriminate bills while preventing jamming of the bills inside. It is intended to provide a bill validating device.

The banknote S reaching the downstream end of the horizontal transport path 34 is transported by the transport belt 39 of the reverse transport section 22, the delivery roller 40, and the reverse pulley 35 so as to make a U-turn along the reverse transport path 41, and the bill outlet Guided to 5.

When the bill S is identified as a true bill by the discrimination mechanism 7, the bill S is discharged to the outside through the bill discharge port 5 by continuing the rotation of the conveyor belt 39. It is placed on the bill placement part 16 of the bill storage part 19. When a plurality of bills S are continuously inserted from the bill insertion slot 4 and all of them are identified as true bills, as shown in FIG. Are sequentially stacked.

On the other hand, when the bill S is recognized as a fake bill by the discrimination mechanism 7, the bill S reaches the downstream end of the horizontal transport passage 34, after a predetermined time has passed, or when the transport belt 39 Is fed out by a predetermined amount, the rotation of the conveyor belt 39 stops. Specifically, the control circuit controls a drive motor that rotationally drives the transport belt 39 (lower roller 38), and as shown in FIGS. 6 and 7, the bill S is approximately 2/3 from the bill outlet 5. When exposed,
In other words, the bill S is transferred between the transport belt 39 and the reverse pulley 3.
The drive motor is stopped so as to be sandwiched by about 1/3 by 5 and stay at the bill outlet 5. Accordingly, the user can easily recognize that the bill S that has not been completely discharged to the bill storage unit 19 and has remained at the bill outlet 5 has been identified by the identification mechanism 7 as a fake bill.

In this case, the case 3
The sounder (not shown) emits a warning sound. This allows
In addition to the bill S staying at the bill outlet 5, the sounding device emits a warning sound, so that the bill S is also a fake bill, appealing to the user's hearing, and further raising the user's attention,
The situation can be communicated reliably.

Further, in this case, the display 11 on the front of the case 3 displays characters indicating that the bill S has been identified as a fake bill. As a result, in addition to the fact that the banknote S has stayed at the banknote outlet 5, the display 11 displays that fact in characters,
It is possible to further appeal to the user's vision that the bill S is a fake bill, to further alert the user, and to surely convey the situation. Note that a lamp that emits light with a conspicuous color (for example, red) may be provided instead of or together with the display 11.

As described above, when the bill S stays at the bill outlet 5, the user can easily grasp the exposed portion of the bill S and pull it forward to easily move the bill S from the bill validator 1. Can be taken out. Further, when the user presses the switch 14 on the front of the case 3, the bill S can be automatically taken out. That is, when the switch 14 is pressed, the stopped drive motor operates again, whereby the transport belt 39 rotates, and the bill S is completely discharged from the bill outlet 5. As described above, the banknote S is automatically ejected only by operating the switch 14, so that the user does not need to pinch and pull out the banknote S, and the banknote S can be easily taken out from the banknote outlet 5. be able to.

As described in detail above, according to the bill validator 1, the user can easily determine the authenticity of the bill S by observing the discharge state of the bill S at the bill outlet 5. In addition, even when the banknote S is identified as a fake bill, unlike the conventional case, the banknote transport mechanism 6 transports the banknote S toward the banknote outlet 5 and reverses the banknote S to the banknote insertion slot 4. Since there is no bill, it is possible to prevent the bill S from being jammed inside the apparatus, and it is possible to continuously insert the bill S from the bill insertion slot 4. As a result, the authenticity of the bill S can be efficiently identified. . Further, regardless of the authenticity of the bills S, the bills S are discharged to the outside through one bill outlet 5, so that there is no need to provide a mechanism for sorting the bills S according to the authenticity of the bills S. It can be manufactured at a low cost.

The bill insertion slot 4 and the bill ejection slot 5
Are opened in the same direction and are connected by a bill transporting path including a curved reverse transporting path 41 and a horizontal transporting path 34, so that the entire apparatus is compared with a case where the insertion and discharge of the banknote S are performed in a straight line. Can be made compact and the usability of the device can be improved.

The present invention is not limited to the above-described embodiment, but can be implemented in various modes. For example, the present invention can be applied to a large-sized bill validator other than a tabletop type. Also, according to the bill to be identified,
By configuring the identification mechanism, it is possible to identify various bills of various countries. Furthermore, the bill identification device of the embodiment is one in which the user inserts the bills one by one into the bill insertion slot, but is provided with an auto feeder that automatically sends out a bundle of bills one by one near the bill insertion slot. Is also good.
