Abstract

<P>PROBLEM TO BE SOLVED: To provide a paper sheet processor which processes a header card and paper sheets in batch by recognizing the header card even when both of the header card and paper sheet are taken. <P>SOLUTION: With respect to the standard thickness Ts of paper sheets, the standard thickness Hs of header cards is set to be 1.5Ts. The header cards are inserted to the breaks of respective batches to form a batch P1 and a batch P2, e.g. to be supplied to a supplying part 10, and taking out of the paper sheets is started. The paper sheets are taken out in order from the paper sheet P of the batch P1. When the both of the two of the paper sheet P1n and the header card H1 are taken, a header card detector 8 does not detect the header card H1 but a paper sheet discrimination device 19 detects it. As the result of the discrimination, the front surface of the stacked sheets is a paper sheet and the rear surface thereof is a header card, so that they can not be discriminated in discriminating the kinds of paper sheets and discriminating authenticity. However, thickness in a prescribed range is classified into a class D by thickness detection, so that the taken sheet is discriminated as the header card. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention relates to a paper sheet processing apparatus capable of batch processing for sorting and discriminating paper sheets such as securities using a header card, and relates to a header card when both the header card and the paper sheet are taken out. It is related with the paper sheet processing apparatus which can detect.

A paper sheet processing apparatus for processing paper sheets such as securities takes out and transports a batch of paper sheets that are input at a time, one by one, and the type of the paper sheet is determined by a paper sheet discrimination device. (Hereinafter referred to as ticket type) Discrimination, conveyance direction discrimination, authenticity discrimination (whether genuine or counterfeit) and correctness determination (whether recirculated or non-reflowable) This is a device that sorts paper sheets on the basis of the determination result and distributes the paper sheets to a processing device such as a sealing device or a stacking device.

At this time, in a paper processing apparatus capable of batch processing, when performing small batch processing, it is called header card processing in which a header card is inserted at the end of the paper sheet for each batch processing unit and processed separately. The method is known. In addition, there is also a method of using a dummy card at the beginning of the paper sheet, inserting a paper sheet to be processed after that, and inserting and sorting a header card at the end,
Basically, the same method is used.

Since the header card is different from the paper sheet to be processed, the header card is handled as a later-excluded ticket and is collected in the rejected ticket accumulating unit. At that time, it is understood that the paper sheets sandwiched and accumulated between the header cards are the paper sheets excluded by the batch processing. Therefore, an identification code such as a barcode is printed on this header card.

In this header card processing, processing steps are performed in three stages (pre-processing, device processing, and rejected ticket processing).

The first stage is a pre-processing stage, which is a stage before paper sheets are processed by the paper sheet processing apparatus. In this phase, the operator accepts paper sheets and issues a header card, and sets the header card, paper sheets, header card, paper sheets,. The header card is for distinguishing a set of one paper sheet and a set of the other paper sheet, and a combination of the header card and the paper sheet forms one batch. Therefore, a plurality of batches exist in the processing box.

The second stage is an apparatus processing stage. Paper sheets and header cards in the processing box set by an operator (hereinafter, the paper sheets and header cards are collectively referred to as a medium) are paper sheet processing apparatuses. This is the phase for sorting. When the operator sets the medium in the processing box in the take-in section of the paper sheet processing apparatus and issues a count start command, the paper sheet processing apparatus takes out the set paper sheets one by one at regular intervals. The paper sheet discriminating apparatus detects the type of paper sheet and the header card.

The taking-in unit is provided with detecting means for detecting the header card, and means for temporarily stopping the taking-in process when the header card is detected by the detecting means.

The third stage is a rejection ticket processing stage in which the operator processes the rejection ticket. In this phase, the operator inputs a paper sheet that has been excluded from the paper sheet processing apparatus, using the identification number printed on the header card as a key. On the other hand, when header cards and paper sheets are taken out at the same time, it is difficult to identify them with the header cards. Therefore, a method of adding barcodes to both sides of the header cards is known (see, for example, Patent Document 1). .
Japanese Patent No. 2798979 (Page 3, FIG. 2)

However, in the paper sheet processing apparatus described in Patent Document 1, when the barcode on both sides of the header card can be recognized, it is recognized as a header card, but if only one side is recognized, it is considered that overlap has occurred. The paper sheet handling machine was stopped. That is, there is a problem that the header card cannot be correctly recognized, and the batch separation of the front and rear batches with the header card as a boundary may not be performed correctly.

The present invention has been made to solve the above-described problem. A paper sheet processing apparatus that can correctly recognize a header card and perform batch processing even when two header cards and paper sheets are taken. The purpose is to provide.

In order to achieve the above object, a sheet processing apparatus according to claim 1 of the present invention takes out one sheet at a time from a supply unit that collectively supplies sheets sorted by card for each processing unit by using a takeout means. A sheet processing apparatus that sorts and processes the card and the paper sheet, and is inserted into a rear end of the paper sheet divided for each processing unit, and identifies the processing unit A card provided with a code, a card detection means for detecting the card, a discrimination means for discriminating the paper or the medium made of the card, a reading means for reading the identification code, and the medium to be conveyed Thickness is detected, and based on the detection result, the first classification that the paper sheet is one thickness, the second classification that the card is one thickness, the two paper sheets The third category of thickness and the paper sheets and the card Thickness detecting means for detecting which is one of the fourth classification, and the card based on the detection results from the card detecting means, the determining means, the reading means and the thickness detecting means. And control means for determining whether or not.

According to the present invention, even when two header cards and paper sheets are taken, the header card can be correctly recognized, so that batch processing is possible.

FIG. 4 is a diagram showing the state of the paper sheets loaded in the processing box. The illustrated example shows a state in which two batches of the paper sheet group P1 and the paper sheet group P2 are stacked on the processing box. The first batch P1 includes the paper sheets P11... The paper sheets P1n and the header card H1. The next batch P2 is composed of a sheet P21... A sheet group P2n and a header card H2, and is supplied to the supply unit 10 so as to be taken out first from the sheet P11. A barcode H1B is printed on the header card H1. Similarly, a barcode is printed on the header card H2. Since the barcode H1B and the barcode H2B (not shown) are barcodes for distinguishing between the batch P1 and the batch P2, different data are printed.

FIG. 5 illustrates a state where the paper sheet group P1 and the paper sheet group P2 illustrated in FIG. 4 are supplied to the supply unit 10 of the paper sheet processing unit 1. As shown in the drawing, sheets are taken out one by one from the paper sheet P11 of the paper sheet group P1.

The discrimination unit 83 receives this electrical signal and detects the header card by comparing it with a predetermined discrimination level. Although the case where a green light emitting LED is used for the light emitting unit 81 is shown, a white LE is used for the light emitting unit 81.
The same result can be obtained by using D and using the optical filter matched to the background color of the header card for the light receiving unit 82.

FIG. 6 shows a state in which two header cards H1 and paper sheets P1n are taken and conveyed in the direction of the arrow B shown in the figure. In this case, the header card detection device 8 uses the header card H1.
Since the background color cannot be detected, the header card H1 is not detected.

FIG. 7 is a diagram showing the relative thicknesses of the paper sheets and the header card. Here, as a specific example, it is assumed that two sheets P1m, sheets P1n, and header cards H1 of the batch P1 are taken, and a method for detecting the header card H1 in that case will be described.

First, set the standard thickness for paper sheets and header cards. In this embodiment, when the standard thickness of one sheet P is Ts, and the standard thickness Hs of one header card is set to 1.5 Ts, the sheet and the header card are singly or two. When it is removed, the thickness becomes a value shown in the following formulas (1) to (4).
Standard thickness of one sheet of paper: Ts ... (1)
Standard thickness of one header card: Hs = 1.5Ts (2)
Standard thickness of two paper sheets: 2Ts (3)
Standard thickness of 1 header card + 1 sheet of paper: Ts + Hs = 2.5Ts (4)
Next, when the thickness t detected by the thickness detection device satisfies the following expression, the paper sheets are classified into a classification A (first classification) and a classification B (second classification) using the above expressions (1) to (4). ), Classification C (third classification) and classification D (
(4th classification).
Classification A (one sheet of paper): Ts−Δt ≦ t ≦ Ts + Δt (5)
Classification B (one header card): 1.5Ts−Δt ≦ t ≦ 1.5Ts + Δt · (6)
Classification C (two paper sheets): 2Ts−Δt ≦ t ≦ 2Ts + Δt (7)
Category D (1 header card + 1 paper sheet):
2.5Ts−Δt ≦ t ≦ 2.5Ts + Δt (8)
FIG. 8 is a diagram for explaining the classification of the thickness according to the combination of the paper sheet and the header card shown in FIG. At this time, the allowable value Δt needs to be set so that, for example, the upper limit value of class A is equal to or lower than the lower limit value of class B. The same applies to other classifications. As described above, by setting the standard thickness Hs of one header card and setting the allowable value Δt, it is possible to classify even when two conveyed paper sheets and header cards are taken. it can.

Next, a batch process when two sheets and a header card are taken based on the above-described method will be described. In FIG. 5, the batch P1 and the batch P2 are supplied to the supply part 10, and extraction is started. When the sheets P1n and the header card H1 are taken out in order from the sheets P11 of the batch P1, the header card detection device 8 described above does not detect the header card H1, and one sheet of paper is obtained. The paper sheet is discriminated by the paper sheet discriminating device 19. As a result of the determination, the two sheets of paper sheets that have been taken are paper sheets on the front side and header cards on the back side, and therefore cannot be determined by ticket type determination and authenticity determination as paper sheets. However, since the thickness in a predetermined range is classified into the above-mentioned classification D by the thickness detection, it is determined as a header card. By this determination, the sheets of the batch P2 are continuously taken out and determined. The paper sheet P1n conveyed together with the header card H1 is removed together with the header card H1 in the rejected ticket stacking unit 80.
Is accumulated.

When the batch P1 and batch P2 co-determination processing is completed in this way, the third-stage exclusion ticket processing is performed for both the batch P1 and the batch P2 by the operator from the above-described registration information PC 130 for rejection ticket input. The detection area for detecting the thickness investigates the characteristics of the paper sheet to be processed, and uses the portion where the thickness fluctuation of the paper sheet is small with printing ink or the like, thereby obtaining the allowable value Δt shown in FIG. A large value can be set, which is preferable.
