Abstract

PURPOSE:To prevent skip-printing and double-printing by accurately confirming 'line shift printing information' without mistakes, by judging whether line printing information is 'normal printing information' or 'line shift printing information ' by comparing line searching information analytical results before and after a line. CONSTITUTION:In searching the final printed line of a passbook 3, final printed line information by an optical detection means is compared with the final printed line information stored on a magnetic stripe 27 and, when both informations coincide, said final printed line is determined as it is and the line under said line is set in front of a printing head 8 and processing advances to the next printing processing. Even if both informations do not coincide, a message 'the dealing of this passbook is impossible' is issued and, without interrupting processing, the final printed line magnetically recorded on the magnetic stripe 27 of the passbook 3 is again scanned by an optical detection means 2 to calculate the number of black spot bits which are, in turn, compared with that of the final printed line obtained by actually scanning the passbook 3 by the optical detection means 2 to reexamine and determine the final printed line.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a process of searching for the presence or absence of information such as letters and numbers printed on a printing medium (hereinafter abbreviated as printing). For example, the present invention relates to a search processing method for detecting the presence or absence of printed information in which the presence or absence of printed information printed on a particular line of a bankbook is detected and processed by an optical detection means in an automatic teller machine that handles bankbooks, a bank teller machine, etc.

[Background of the invention]

In a conventional device, the presence or absence of printed information on a printing medium is searched by an optical detection means 2 having dozens to hundreds of inexpensive line sensors 1 arranged on the side, as shown in FIG. 5(a). Printed information on 3 (Business handling processing department 81. Processing month 8
2. Processing date 83. Haiphong mark 84) Up arrow x1
Each line sensor 1 sequentially scans the line sensor 1 in the direction (as shown in FIG. 5(b), while the print medium 3 is conveyed at a constant speed in the direction of the arrow ) The search principle is as shown in Figure 5 (
As shown in c), each line sensor 1 sequentially receives the reflected light after the light emitted from the optical detection means 2 hits the printed information 81, 82, 83, 84, etc. on the printing medium 3, and this The amount of reflected light is waveform-shaped and converted into sunspot bit information.
The search information is sequentially stored in the memory mentioned above.

After all the search information from the top to the bottom of the print medium 3 has been stored in the memory, the search information on the memory is divided into equal parts corresponding to each row, and the search information divided into equal parts (hereinafter referred to as black dot bits) is divided into equal parts. Information) is added for each line, and when the added number of black dot bits reaches a uniform predetermined number of black dot bits or more, it is determined as a "line with print information". I was doing a search.

Then, the final printed line information obtained by the optical detection means 2 obtained in this way and the final printed information magnetically stored on the magnetic stripe (to be explained in detail later) attached to the spine of the passbook 9. The information on the last printed line is conveyed (the reason for conveying is to prevent line skipping and double printing), and only when the last printed line information on both sides match, the information below the last printed line is conveyed. A predetermined printing process is performed after the line. If there is a mismatch, the process will be interrupted and
After giving guidance such as "This passbook cannot be used for transactions" to the end user, the passbook is released to the end user and the process is completed.

However, with this conventional search processing method for checking the presence or absence of printed information, there is no problem when printed information 81, 82, 83, 84, etc. are printed neatly near the center of the line as shown in Figure 6. Not though.

Printed information 81.8 as shown in the 3rd line printing in Figure 7
2, 83, 84, etc. are printed beyond the 3rd line, which is the original printing line, and are printed across the 4th line, depending on the amount of protrusion, it is recognized that it is originally printed. There is a high probability that the line below the right line, that is, the fourth line, will be recognized as the last printed line, and therefore, as described above, the last printed line information obtained from the optical detection means 2 and the magnetic stripe This tends to cause a mismatch with the stored last printed line information.

"Cannot be handled with this passbook" occurs frequently, and the subsequent processing cannot proceed, so it is necessary to switch from automatic processing to manual processing, and there is a high probability that the acquisition will be intervened in the middle of the processing, which is troublesome. there were.

[Purpose of the invention]

An object of the present invention is to provide a search processing method for the presence or absence of printed information that can correctly recognize ``misaligned printing information'' as ``misaligned printing information'' in order to eliminate such interlayer points in the prior art. There is a particular thing.

[Summary of the invention]

When a human visually recognizes misaligned printing, the misaligned printing is recognized based on the weight balance of the amount of protrusion from the relevant line.The present invention uses optical detection based on the same recognition standard as the human visual recognition standard. applied to the algorithm of the means,
Compare the search information analysis results of the lines before and after the line with the search information results of the line to determine whether the printing information of the line is "normal printing information" or "misaligned printing information", and check for skipped lines and double printing. This is a search processing method for the presence or absence of printed information that prevents this.

Scanning information (number of black point bits a.

b, c...).

A feature of the present invention is that when searching for the last printed line of the passbook 3, as a means to increase the search reliability, the last printed line information is stored on the magnetic stripe 27 and the last printed line information by the optical detection means 2 described above. If the surface information matches the last printed line information, that line is determined to be the last printed line, and the line below that line is set in front of the print head 8 for next processing. It is natural that the process will proceed to the printing process, but if there is a discrepancy, the magnetic stripe 2 of this passbook 3 will be printed again without issuing a message "This passbook cannot be used" and interrupting the process.
The number of black dot bits when the optical detection means 2 scans the last printed line magnetically recorded on the passbook 7 and the last printed line obtained by actually scanning the passbook 3 with the optical detection means 2. Its main feature is that it compares the number of black dot bits and re-examines and determines the final printed line.

In other words, to explain this major feature with reference to FIG. 3, the printing on the third line protrudes downward from the third line and extends to the fourth line. When such printing is detected by the optical detection means 2, the print information is originally printed on the third line, but there is a high probability that the last printed line is determined to be the fourth line. Therefore, in the present invention, when the last printed line detected by the optical detection means 2 and the last printed line stored on the magnetic stripe 27 do not match, the optical detection means 2 detects the line as the last printed line. The black dot bit number d of the fourth line is compared with the black dot bit number C when the optical detection means 2 searches for the third line, which is the last printed line recorded on the magnetic stripe 27. If C≧d, print information 81'
, 82', 83', and 84' are recognized as printed information shifted from the third line to the fourth line toward the opening, and the printed information 81', 82' is printed.

83' and 84' are considered to be printed on the third line. In other words,
Weight balance processing is performed on print information using line sections as boundaries. Then, print head 8 prints the fourth line of one passbook 3.
The print head 8 is set before printing, and a printing process, which is a primary process, is performed using a known print head 8.

If c < d, if the same process as the above method is executed, the print information 81', 82', 83'' on the third line will be printed.
84'' etc. and the print information that is about to be printed on the 4th line overlaps, which is the so-called double printing. It cannot be handled with a passbook.”
After notifying the end user of the above using known voice guidance, film guidance, etc., the passbook 3 taken into the passbook handling bag w90 is released into the insertion slot 91, and such passbook 3 is manually processed at the counter. Provide a message to the end user informing them that they will receive a call, and switch to the counter guidance.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be implemented with various modifications. For example, in this embodiment, based on the last printed line information (third line) stored on the magnetic stripe 27, the black spot bit number C obtained by scanning that line with the optical detection means 2 and the optical The target detection means 2 scanned the line recognized as the last printed line, that is, the fourth line, and compared it with the number of black dot bits d to determine the last printed line. The last printed line may be searched by using a search algorithm.

〔Effect of the invention〕

As described in detail above, according to the present invention, even if the printing is slightly shifted from the printing line that should be printed, it is not only possible to recognize which line the misaligned printing is, but also to make it possible to By attachment.

Algorithm-wise, it is possible to correct the misaligned printing to a normal printing state, and prevent false detection of the presence or absence of printed information, thus increasing the reliability of automatic teller machines, bookkeeping machines, etc., which are the automatic machines to which the present invention is applied. , which has the effect of achieving faster processing.
