CONSTITUTION:When a plurality of sheets, e.g., bills, are inserted, a plurality of the sheets are forcibly displaced in a conveying direction by means of a sheet displacing mechanism 20. The length of the displaced sheets is detected by a length detecting sensor S to detect the number of the sheets.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial field of application This invention relates to a paper sheet receiving system, such as a paper sheet receiving system, which is internally configured in an automatic bill payment machine that automatically delivers paper sheets such as bills, for example. The present invention relates to a control device, and more particularly, to a paper sheet capture control device that has excellent paper sheet capture performance.

(b) Conventional technology Generally, when paper sheets such as bills and paper strips are taken into the interior and processed, the paper sheets are held and conveyed one by one between rotating bodies such as conveyor rollers and conveyor belts. I'm taking it in.

If a plurality of paper sheets are mistakenly taken in at the time of this taking-in, there is a risk that the plurality of sheets may jam in the latter stage, causing a conveyance failure, or be erroneously cut by the cutting device in the latter stage.

Therefore, an optical detection sensor that optically detects paper sheets is used as a means for detecting multiple paper sheets.
This optical detection does not have problems with low reliability, such as erroneously detecting wrinkles or stains on paper sheets. To provide a paper sheet intake control device capable of accurately detecting the number of paper sheets taken in and stably controlling the intake one by one.

(d) Means for Solving the Problems The present invention provides a paper sheet intake control device that takes in paper sheets inserted through an insertion slot one by one and processes the paper sheets, which Multiple sheets of paper sheets are inserted at the starting end of the path by restricting the rotation of one of the opposing rotating bodies with an insertion interval wider than the thickness of one sheet and narrower than the thickness of two sheets. The paper sheet shifting mechanism is configured to shift paper sheets in a sashimi-like manner, and the paper sheet intake control device is equipped with a length detection sensor that detects the length of the paper sheets at the rear stage of this paper sheet shifting machine. be.

(e) Effect of the invention According to this invention, when a plurality of paper sheets are inserted,
A paper sheet shifting mechanism forcibly shifts multiple sheets of paper in the transport direction, and a length detection sensor detects the length of the shifted sheets to detect multiple sheets of paper. do.

(f) Effects of the invention Therefore, the ingestion of multiple sheets of paper can be reliably detected at the initial stage of ingestion of paper sheets, and it is possible to prevent multiple sheets of paper from being taken into the interior by mistake. It is possible to perform stable import processing without erroneous cutting in case of clogging.

In particular, the paper sheet sliding mechanism can forcibly shift the paper sheet itself into a state where multiple sheets can be detected, ensuring the detection of multiple sheets and eliminating wrinkles and wrinkles in the sheets. Highly reliable import processing that avoids false detections caused by dirt is possible.

(g) Examples An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 2 shows an external view of the automatic toll payment machine, and this automatic toll payment machine 11 has a CRT 12 on the front panel that also serves as a touch panel to guide the customer (payer) in operating the machine.
, a bill insertion slot 13 , a bill exit 14 and a coin exit 15 for inserting the payment fee, and a handling display 1
6, an attendant call button 17, an attendant key 18, and a customer approach detection sensor 19.

The bill used in the above-mentioned automatic toll payment machine 11 is, for example, a call charge bill that is mailed to the user from a public equipment company such as a telecommunications and telephone equipment company, and includes various payment information necessary for payment. ing.

FIG. 3 shows a schematic diagram of the internal structure of the automatic bill payment machine 11, in which a bill insertion slot 13 at the left end of the drawing is connected to a bill slip machine top 20, which will be described later. As an insertion path to the cutter 21 installed inside,
The bill conveyance path 22 formed by the upper and lower belt conveyors 22a and 22b is substantially linear.

This bill conveyance path 22 has a bill insertion slot 1.
3 to the cutter 21, a tax office approved stamp unit 23, an OCR head 24, and a printer unit 2.
5. Each processing element is arranged in the order of the receipt and stored stamp unit 26, and the bill A inserted through the bill insertion slot 13 and the bill shifting mechanism 20 is first moved to the position of the OCR head 24. and the head is bill A.
The written contents are optically read and checked, and if this check is normal and the required fee has been inserted, a stamp is stamped on the receipt section with the tax office approved stamp unit 23, and after the stamp is stamped, the bill is processed. The document A is conveyed to the right in the drawing toward the receipt and storage stamp unit 26, and on the way there, the printer unit 25 prints the receipt date and storage date.

The aforementioned cutter 21 then cuts the bill A into three pieces, and after cutting, only the receipt portion is sent back to the bill insertion slot 13 via the bill conveyance path 22 and returned to the customer.

The other two bill parts pass through branch conveyance paths 27 and 28 after the cutter as storage paths, and then go to the upper and lower storage boxes 29 and 30.
The distribution is stored separately via the flapper f1.

Incidentally, since the customer may forget to take the receipt part sent back to the bill insertion slot 13, in that case, the receipt part is taken in again and stored in the collection box 31 via the flapper f2.

The above-mentioned bill shifting mechanism 20, as shown in FIG.
An upper gate roller 32 whose rotation in the taking-in direction is regulated and a lower feed roller 33 which rotates in the taking-in direction are vertically opposed to each other on the starting end of the insertion slot corresponding to the bill insertion slot 13. Both rollers 3
By setting and arranging the vertically facing interval of 2.33 at an interval wider than the thickness of one bill and narrower than the thickness of two bills, and setting it to such a q-ra interval, here. Allows one sheet of bill A to be taken in, and when multiple sheets are inserted in stacks, bill A... is shifted in the conveying direction like a sashimi by the rotation/non-rotation action of these rollers. By detecting this as an abnormal length with the length detection sensor S in the latter stage, it is possible to accurately detect that a plurality of bills A... have been erroneously inserted into the bill insertion slot 13, and take appropriate measures. The customer is notified of the insertion error and instructed to insert the sheets one by one again.

Therefore, it is possible to control and manage to always take in one sheet at a time, and to take precautions to prevent paper jams from occurring inside.

Next, a description will be given of the import processing operation when a bill is inserted into the automatic toll payment machine.

Now, when bill A is inserted into the bill insertion slot 13, if it is a regular one-sheet insertion, the bill shifter side 20 only applies a feeding action to bill A, and bill A is inserted into the bill insertion slot 13. It is taken inward via the conveyance path 22 and subjected to predetermined internal processing at a later stage.

By the way, there are multiple bills A in the bill insertion slot 13...
If A is inserted at the same time, multiple bills A...
As shown in FIGS. 4(A) and 4(B), the bill shifting mechanism 20 forcibly shifts the bills in the conveying direction, and the length of the shifted bills is taken as one sheet. The insertion of multiple bills is detected by the detection sensor S detecting an abnormality.

In addition, even if the length detection sensor S has an abnormality and cannot be detected, the bill A that has been captured in the form of sashimi
For ..., the contents of bill A are scanned by OCR head 2.
At step 4, an optical reading check is performed, and during this reading, it is not possible to read completely due to the overlapped portions that overlap like sashimi, and a reading failure occurs and it is possible to detect that multiple sheets have been inserted.

When the insertion of multiple coins is detected, the customer is informed, for example, via the CRT 12, that the transaction processing is inappropriate, and the customer is guided to insert the coins one by one.

As mentioned above, it is possible to reliably detect multiple invoices being taken in at the initial stage of invoice importing, preventing multiple invoices from being erroneously taken into the internal unit, and therefore ensuring stability with no paper jams or erroneous cuts. It is possible to perform import processing.

In particular, the bill shifter allows you to forcibly shift the bill itself to a state where multiple bills can be detected.
It is possible to reliably detect multiple invoices and perform highly reliable import processing that avoids false detections caused by wrinkles or dirt on the invoices.
