Abstract

PURPOSE:To perform a reading process in one lot on various kinds of diversified slips, by issuing an ID reading command plural times to one slip and, at the same time, supplying an optical character reader (OCR) with the document format information (IDFC) of the row of relevant data from the ID reading results. CONSTITUTION:Upon receiving IDFC from a system control section 17, an OCR control section 15 starts the reading of ID rows. At this moment the IDFC of ID=10 is first transferred from the system control section 17. The OCR control section 15 reads the ID row in accordance with the IDFC and, when the reading results are those other than '10', the system control section 17 transfers the IDFC of ID=20. Upon receiving new IDFC, the OCR control section 15 surely saves the previous IDFC in a memory. When all data rows are read, the system control section 17 designates a pocket number and discharges the slip to a sorter section 16 through the OCR control section 15. Therefore, the necessity of prior hand sorting works can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a character reading device that can process the characters all at once even when a large number of I-type slips are mixed.

(Prior Art) In a conventional optical character reading device (hereinafter referred to as OCR), as shown in the flowchart of FIG. 3(B),
When reading forms of the same size and different reading formats, an identification number (hereinafter referred to as ID) is placed at a predetermined position at the beginning of the line.
After reading this ID, the reading format was determined.

However, as the types of documents become more diverse, it becomes difficult to limit the ID to a specific location, and it becomes necessary to set the ID in a different location.
When processing with CR, first manually classify the forms into those with the same ID, and then use OCR to classify the forms into L? , had to be processed.

(Problems to be Solved by the Invention) As mentioned above, in conventional OCR, as the types of documents become more diverse, it becomes necessary to manually classify the documents in advance before the OCR reading operation. If there are a mixture of items with different row positions, batch processing cannot be performed, which poses a problem in that business efficiency decreases.

The present invention solves the above-mentioned conventional problems, and the number of documents is 1/L1.
To provide a character reading device capable of batch processing even when a variety of forms with 10 line positions coexist and greatly improve business efficiency of form processing.

[Structure of the Invention] (Means for Solving the Problems) A character reading device according to the present invention includes means for storing a plurality of identification number a7t pick-up # information and a plurality of form format information corresponding to the information. , an il+ν separate number reading means for reading the identification number for each form based on the information, and a 7e for this identification number.
and a character reading means for reading the characters on the form according to the form format information that is transmitted to the IC according to the reading result of the reading means, and a form in which a plurality of forms with different recording positions of identification numbers are mixed. It is characterized by reading characters in groups.

(Function) According to the present invention, the OCR control unit that controls the entire OCR receives document format information (hereinafter referred to as IDFC) and ID reading commands multiple times, and when the Nth IDFC is received. I for the N-1st time in
Save the DFC, and then store multiple IDFCs in the system control unit, issue multiple IDUe retrieval commands for one form, and retrieve the IDFC of the corresponding data line based on the ID reading result. By providing the information to the OCR, the conventional prior manual classification work is no longer necessary, and it is possible to collectively read a wide variety of documents with different ID line positions.

(Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment in which the present invention is applied to OCR, in which 10 is a photoelectric conversion section that reads characters/4' turns by optical scanning, and 11 is a photoelectric conversion section that reads characters/4' turns. A line buffer section stores read characters/4' turns in line units; 12 is a character cutting section that cuts out the character pattern for each line one character at a time; 13 is a dictionary section that stores the character pattern cut out one character at a time. 14 is a dictionary unit that stores standard character patterns, J5 is responsible for controlling the entire OCR, and accepts IDFC and ID reading commands multiple times, as well as accepting the Nth IDFC. The QCR control unit 16, which has a function of saving the N-1 IDFC, stores the read form, for example, in the I
A sorter section with multiple pockets for sorting documents into D units;
12 provides reading commands, IDFCs, data files, etc. to OCR, and also provides V&F for multiple IDFCs.
This is a system control unit that has the function of issuing a command to read the ID multiple times for one form, and providing the OCR with the IDFC of the corresponding data line based on the ID a and the reading result.

FIG. 2 is a diagram showing an example of a form for 34Jf class prisoners e (B) and (C) with different ID setting positions 1 in an embodiment of the present invention, and the diagonal portion in the diagram indicates the ID line. , (D) shows a hypothetical diagram in which three types of ID rows, prisoner to (C), are combined and vomited.

FIG. 3(A) is a diagram showing the operation flow of the OCR control section in FIG. 1.

The operation of the embodiment of the present invention shown in FIG. 1 will be explained. When an OCRVC reading command is issued from the system control unit urj:s17, the OCR control unit 15 starts FEED of the form, receives the IDFC from the system control unit 17, and starts reading the ID line. At this time, OCR has Ki 2
Assuming that the three types of forms shown in FIGS. (A) to (C) are mixed, IDF'C with ID=10 is first transferred from the system control unit J2. OCR? The l1ll arrival unit 15 reads the ID line according to this IDFC and transfers the result to the system control unit 17. If the read result is blank data or data other than "10", the system control iJ7 next transfers IDFC of ID=20. Similarly to the above, if the reading result is other than “20#”, the next ID=

When the R control control unit receives an IDFC, it is sure to save the previous IDFC in the memory. This occurs because it is necessary to compare the line position of the new ID with the previous line position, check whether they are in the same line position, and perform conveyance control.

When all data rows have been read, the system control unit J7
For example, the pocket number is specified to the sorter section 16 via the OCR control section 15, and the form is ejected.

The above is an explanation of the basic operation in one embodiment of the present invention. However, by adding a sheet size detection function at the leading edge of the form to the above embodiment, it is possible to handle cases where sheets of different sizes coexist. It is also possible to perform batch processing. In this case, the ID is largely determined by sheet size detection, and then the so-called multi-ID processing according to the present invention is performed, thereby making it possible to read, classify, etc. a wide variety of documents.

[Effects of the Invention] According to the present invention, even when a large number of various forms are mixed together, there is no need for prior manual classification work, and even when a plurality of forms with different ID line positions are mixed. The reading process can be performed all at once, and this brings about excellent effects such as greatly improving business efficiency such as processing for classifying forms.
