Abstract

PURPOSE:To obtain arbitrary field data from a general purpose form by distinguishing character string data and blank data from read out data and by obtaining a separation control signal of a field from the blank data. CONSTITUTION:An OCR10 reads out characters on a form and stores them in buffer memory. When read out data 101 are character data, a data deciding circuit 11 outputs a signal 113 and a character data 114 to a field data editing circuit 13. When they are blank data, the data deciding circuit 11 outputs a signal 112 to a blank data selecting circuit 12, which outputs a signal 121 when a signal 241 is ''1'' and counts up a counter 23 sequentially. As a result the number of blank data appearing after effective characters is set in the counter 23. The blank data between character data are stored in a data buffer 21. A comparator circuit 14 compares a register 22 with the counter 23, and when they are coincident, said circuit 14 outputs a signal 141, activates an output circuit 15 through an OR circuit 33. The output circuit 15 outputs a field data 151.

Description

[Detailed Description of the Invention] (Technical Field) The present invention is a character reading control device, particularly a writing character extraction device that recognizes rounded characters written on a form, which defines a reading target area from the format information of the form. , relates to a character acquisition system [phase] device for obtaining reading results.

(Prior art) A character reading device detects characters written on a form by the position of a line, the position of a character entry area (hereinafter referred to as a field),
The area to be read is determined based on form information such as the number of characters, the size of the character frame, and the character type, and the characters are g-neezed and the result is obtained.

In order to obtain m sentences 'T-' from a certain field as field data using a character reading device in the promotion field, format information that specifies the number of characters as m is required; To obtain a field, format information specifying that the number of fields is in was found in the heart wall.

Therefore, since the field data from a Ruru form is defined in advance as format information and has a fixed number of fields and characters, even if you design a form with versatility, it will not be possible to create a format from the basics. The drawback is that arbitrary field data cannot be obtained.

(Object of the Invention) The present invention eliminates the above-mentioned drawbacks by obtaining field separation tl+lJ from blank data on a form. Registration @ l 1 Itk to provide p
c.meru.

(Structure of the Invention) According to the invention Means to obtain a signal and AI self-separation price 1g
There is also a means for separating and outputting character string data according to the symbol, and a character sample control display for displaying the t word and the t g symbol.

(Example) Next, an embodiment of the present invention will be described with reference to the drawings.

Figure 1 is a block diagram of an embodiment of the present invention. Refer to Figure 1.
A data determination circuit 11 separates rank data k and Ml.

A blank data selection circuit 12 that selects the mth blank that obtains all 1H numbers, a ratio that generates a separate fbll n signal, a px unit 14, and a field data edit that is stored separately in the character string data sound data buffer 21 circuit 13
and an output circuit 15 that outputs the character string data of the engineering data buffer 21 as field data to the separation-side OR signal.
It is composed of fL.

Gengaku character coffin device (hereinafter abbreviated as OC) 10 removes the characters on the 1st period vote and stores them in the buffer memo 'J' in UC BIO.
Store K read data.

The data determination circuit 11 determines whether the data 101 outputted from 0CRto is character data or blank data. For character data, signal 113 and character data 1
14 to the field data output circuit 13, and in the case of blank data, a signal 112τ is output to the blank data selection circuit 1.
I will appear in 2.

The blank data selection circuit 12 outputs the signal 121 when the signal 241 is "1", and the counter 23
Count up by 1. When the signal 241 is in the 0'' state, the signal 121 is not output and the counter 23 is not incremented. The 1g signal 241 is initially adjusted to the o'' state by the free lag flop 24. , when character data appears, '1#' is output by signal 113.
changes to the state of Sokubar No. 16 241t, if blank data appears before a valid character, the temperature will remain at 0'', and if it appears after an M effective character and 7ζ, the state will remain at ``l'', so the counter 23 The number of blank data that appeared after the character is set in f'L.

When the field data editing circuit 13 outputs the data No. 15 113 from the constant circuit 111Jh, the counter 231
/c The blank data for the individual characters being set is stored in the data buffer 21. The character data 23τ (=7) is erased, and the character data 114τ data buffer 21 &C are calculated. In this case, the 7-rank data is not output, and only the character data 114 is stored in the data buffer 21.The counter 23 stores the number of blanks before the character data 114 appears, that is, the number of blanks between valid characters. Since the number is about to be set, the data buffer 21 stores IIr blank data fL between the two character data.

10,000, the comparison circuit 14 compares the register 22 and the counter 23, and outputs No. 46 141 if they match. The register 22 contains the field data τ min 1; ``The number of blanks between the M effect characters or L:) is set to 2, and then (N-1141 is the field data separation 111'' signal) 1g'□ No. 141 touches the OR circuit 33 and becomes a signal 331, which activates the output circuit 15.

The output circuit 15 outputs the character data (1 data) stored in the data buffer 21 in sequential order and outputs it as field data 151.

Signal 331 is sent by flip 70 knob 24 @241
(Since the state of r"0" is initially sized, the blank data is equal to or larger than the opening value of the register 22.) It is possible to limit the field data even if it is uniform.

In addition, since the counter 23t of the input number j31 is initialized, the blank data L data buffer 21 for storing field data is not stored therein.

Note that when the end 1 go number 111 of the read data is output from the data judgment circuit 11, also in this case, the OR circuit 33 outputs the go number 331, so the output circuit 15 operates in the same manner.

An example of separating the field data when two or more blanks are specified, that is, setting 12# in the register 22 and yc, is shown in which the field data is separated into one small block and output! Sign.

In this way, by setting the number of blanks between valid characters that separate fields in the VC register 23,! ;
+ It is possible to obtain any field data from the captured data.

(Effects of Investigation) As described above, the present invention makes it possible to obtain arbitrary field data for the same form without having to read all the format information of the form. Since as many as 74 fields of field data can be obtained from a single glaze type slip, it is easy to design a versatile form.
