Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet conveying apparatus for conveying paper sheets such as banknotes, and more particularly, a paper sheet conveying apparatus capable of illuminating the vicinity of a sensor that detects a jamming failure of a paper sheet. It relates to the device.

[0002] Recently, an automatic teller and payment machine (Automatic Tel) that dispenses and processes banknotes one by one in banks and the like.
ler Machine: ATM) and Cash Dispense
r: hereinafter referred to as CD) etc. are widely used.

In such an apparatus, a plurality of banknotes to be handled may be fed out (double feed), skewed, or broken or broken to prevent normal transfer, causing jamming in the transfer path. So, we have installed jam sensors at various points in the transport path to detect the occurrence of jams,
The operation of the device is stopped to notify the occurrence of the jam failure and the location of the occurrence of the jam failure.

However, when a jam failure occurs, bills may be torn and scattered, and the inside is dark and narrow even when the door of the device is opened to process it, which makes it difficult for maintenance personnel to find it. Because leakage may occur,
There is a need for a method that can completely remove jammed bills and restore them.

[0005]

2. Description of the Related Art An example of a bill handling device incorporated in a CD will be described with reference to FIG. As shown in the figure, the banknotes 1a are stored by denomination, the storage boxes 2a and 2b provided with the feeding mechanisms 3a and 3b, the reject box 2c for rejecting double-feed and bad banknotes, and the fed banknotes 1a are conveyed. Transport path
4a, a double feed of the bill 1a, a discrimination counter 5 for discriminating right / wrong, denomination and counting the amount to be dispensed, a pool 6 for temporarily pooling the dispensed bill 1a, and a dispensing port 7.

A gate G is arranged at the branch point of the transport path 4a, and jam sensors S1, S2, (not shown) for detecting jam jam of the transported banknote 1a (not shown) are provided at important points (see FIG. 7). It is provided.

As shown in the side views and front views of FIGS. 7 (a) and 7 (b), the conveying path 4a is composed of a plurality of conveying belts 8a and 8b which are in contact with each other. Pulley shaft of conveyor belt 8a
Both ends of 80a, 80b are rotatably supported by the frame 9, both ends of the pulley shaft 80c of the conveyor belt 8b are rotatably supported by the frame 9 and the open frame 10, and both ends of the pulley shaft 80d of the conveyor belt 8b are open frame. It is rotatably supported by 10.

The pulley shaft 80a is connected to a drive source (not shown), the conveyor belt 8a is driven by the rotation of the pulley shaft 80a, and the conveyor belt 8b is driven by the rotation of the conveyor belt 8a, so that the conveyor belts 8a and 8b are driven. The bill 1a is conveyed in the direction of arrow A.

An engaging portion 11 is formed at the lower end of the open frame 10 on the pulley shaft 80d side, and is engaged by horizontal movement of a lock pin 91 slidably inserted in an elongated hole 90 formed in the frame 9. The joint part 11 is engaged and the open frame 10
The upward rotation of the pulley shaft 80c is restricted.

Further, the sensors S1, S2, .. are arranged with the light emitting element and the light receiving element facing each other above and below the conveyor belts 8a, 8b of the conveyor path 4a, and detect the shielding due to the passage of the bill 1a. For example, the sensor S1 and the sensor S2 are arranged at intervals in the conveyance direction of the conveyor belts 8a, 8b of the bill 1a, and the time from when the leading edge of the conveyed bill 1a is detected by the sensor S1 to when it is detected by the sensor S2. Is counted and when it is not detected within a predetermined time, it is determined that a jam has occurred in the transport path 4a between the sensor S1 and the sensor S2.

Below, the jam detection between the sensors S1 and S2 is detected as a sensor.
It is called S1 detection. The same is true between the sensor S2 and the sensor S3. Even normal banknotes 1a may cause jams due to double feed and skew during feeding.
If there are defects such as folds, wrinkles, and tears, even if they are slightly bent, a jam occurs due to skewing during feeding or during transportation.

With this structure, the bills 1a of the amount requested by the customer are stored in the storage boxes 2a, 2b by the feeding mechanisms 3a, 3b.
Are sequentially fed out, are conveyed along the conveying path 4a, are discriminated by the discrimination counting unit 5, and are sent to the pool unit 6.

The counted amount is displayed on a display (not shown), and the banknote 1a of the pool section 6 is sent to the dispensing port 7 and dispensed by the customer's confirmation button input. If there is a double feed or a discrimination failure during this period, the gate G at the branch point of the transport path 4a operates and the reject box 2c rejects it.

Further, when a jam occurs in the bill 1a being conveyed and is detected by one of the jam sensors S1, S2,
The operation of the device is stopped, and the occurrence of a jam is notified by a warning lamp or a buzzer, and the location of the jam is displayed on the display.

Then, the maintenance personnel opens the door of the device and
As shown in FIG. 11, the lock pin 91 that locks the engaging portion 11 of the open frame 10 near the jam occurrence point on the transport path 4a.
Is moved to the left in the figure to unlock the engaging portion 11 and rotate the open frame 10 around the pulley shaft 80c in the direction of arrow B to remove the jammed jam bill and restore it. Then, the open frame 10 is closed and locked with the lock pin 91.

In this way, the jam processing is performed.

[0017]

According to the above-mentioned conventional method, when the occurrence of the jam jam of the bill is notified, the maintenance staff opens the door of the apparatus and opens the open frame to remove the jam bill at the jam occurrence location. Although it has been removed, bills may be torn and scattered when a jam occurs, and since the conveyance path is generally dark and narrow, it is difficult to find and take out bill fragments, so open by removing the fixing tool of the conveyance path. I try to take it out.

However, the illumination may be particularly dark depending on the installation location of the device, and if sufficient illumination is not obtained inside the device, if the bill fragments are left behind, the remaining fragments lead to the next jam failure. There is a problem that there is a possibility.

It is an object of the present invention to provide a paper sheet transporting device capable of brightly illuminating a jam occurrence location and facilitating the processing of jam banknotes.

[0020]

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, 1 is a paper sheet, 4 is a transport path, 12 is at least one at a predetermined location of the transport path 4, and abnormality detection means for detecting a transport abnormality of the paper sheet 1 transported through the transport path 4, Reference numerals 13 are illumination means provided in the vicinity of the position where the abnormality detection means 9 is arranged, respectively.

Therefore, based on the detection output of the abnormality detecting means 12, the conveying abnormality is notified and the corresponding illuminating means 13 is turned on.

[0022]
