Abstract

PURPOSE:To read out handwriting characters written with an optional character pitch by specifying character pitch data in format control data on the unit of length. CONSTITUTION:The user of an OCR specifies a character pitch in a character field through an input device in an external controlling device 1. When the leading bit S of a data F3 indicating the character pitch of format control data FCD is ''1'' and ''0'' respectively, the pitch is specified at every bit S1-S3 in milimeters and inches respectively on one digit basis. After completing the specification, the FCD from the device 1 is stored in a format data storing circuit 3. When a reading-out command is applied from the device 1 to a control circuit 2, the circuit 2 reads out the FCD from the circuit 3 and sends the information of a line to be recognized to a recognition circuit 4. The circuit 4 takes out a character pattern on one character basis by the character pitch specifying data based upon the data F3 to recogniza the character and the recognized result is temporally stored in an answer recording circuit 5 to send to the device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical character reading device that optically reads lip characters written or printed on a form.

[Technical background of the invention]

Conventionally, when reading characters with an optical character reading device (hereinafter referred to as OCR), in the field to be read in the line to be read, the character spacing (character pitch) in the field is selected from among those registered in advance. Reading is performed by specifying one with a code. Generally, this character pitch is 4 characters/inch for Kosho hot character reading p, S
Characters/inch, 6 characters/inch, 6.5mm/character, etc. are too large, and in the case of printed characters, %lO due to printing equipment.
Character/inch is often used.

[Problems with background technology]

Therefore, especially in the case of handwritten characters, it is only possible to read handwritten characters with several pre-registered character pitches such as f: 9, and when printing a character entry frame on a form, the above 9. Printing must be done to match several character pitches.

[Purpose of the invention]

This invention was made in view of the circumstances described in E.
The fin and handle of handwritten characters written at arbitrary character pitch.
An object of the present invention is to provide an optical character reading device that is slow depending on the operation.

[A chest of inventions]

The present invention is an optical character reading device for reading characters written or printed on a form, in which character pitch data in format control data can be specified in units of length.

[Embodiments of the invention]

Hereinafter, a dormitory embodiment of the present invention will be explained with reference to one drawing. FIG. 1 is a schematic diagram of an OCR according to an embodiment of the present invention. In this figure, 1 is an external control device, and this O
We are waiting for a function to manage the entire CC control. Reference numeral 2 denotes a control circuit, which has the function of performing main control of the present invention under the control of the external control device 11. J is format day 11
41gl path, an external device has a function of storing the format control data sent in this way. 4 is a recognition circuit, and under the control of the control circuit 2, a photoelectric switching system (not shown) is It has the function of cutting out and recognizing the photoelectrically converted character patterns of the forms sent from the computer.

5 is the answer memory circuit, and the am circuit 4 is V! The recognized result (answer) is temporarily stored, and this answer is supplied to the external control device 1.

Next, prior to explaining the operation of the above embodiment, FIGS.
Let me explain aQ. FIG. 2 shows the character field of form 1 for reference. In FIG. 2, CF indicates a character frame to be filled in as a reference for writing, DC indicates characters written in the character frame CIF, and P indicates a character pitch.

tig3 is a diagram showing the contents of an example of format control data. In other words, the tt(a
: Integer) The format control data for the character field on the 1st line is data JFI indicating the 1st line position and data ! indicating the reading start position. r! and data F3 indicating the character pitch.

It consists of data F4 indicating the type of character written, data y5 indicating the number of digits, and data y6 indicating the font.

Furthermore, FIG. 4 is a diagram showing the pitch II configuration of data F3 indicating the character pitch in the format control data shown in FIG. In other words, the data F3 indicating the character pitch is composed of 13 bits, and when the first bit B is 11', the character pitch is specified in dmm (t millimeter) units, and the character pitch is specified in units of 10" and 11" inches. is now specified.In addition, the following 12
Bits specify the actual number.

In terms of heel body, each 4 bits in 12 bits are 81.82
．． A 1-digit number is specified for each 83, and the first 4 digits) 81
It is now specified that there is a decimal point after the .

A user of the OCR shown in FIG. 1 first specifies or registers a character pitch in a two-character field using an input device (not shown) of the external control device 10. For example, when specifying 4 characters/inch, data F3 indicating the character pitch is rOJrOloooJrOoooJrooo
oJ, and when specifying a 354 ma theory pitch, it becomes rlJrOOllJrOlolJrOlooJ. For example, when registering the character pitch of &03m grave, the user enters the registration mode using the input device in the external control device 1, and presses the numerical keys rlJ, rsJ, r
Crop in the order of OJ and rsJ and register.

When the user finishes specifying the format control data I shown in FIG. 1st ki foo! The control data is stored. After this, the external control device [
When a read command is given to the control circuit 2 from the control circuit 2, the control circuit 2 reads FO! It performs a compile 9 of nine format control data stored from the data storage circuit 5, and sends information on the line to be recognized from now on to the recognition circuit 4. wml
When path a is given the colored information to be read, it starts recognizing the photoelectric conversion pattern of the bottle line S and sent from a photoelectric conversion system (not shown) controlled by the control circuit 2.

That is, the recognition circuit # uses the character pitch instruction data based on the data F3 indicating the character pitch in the format control data sent from the control circuit #.
1: The light distribution/electrical conversion pattern is cut out into a character pattern of one character, and the characters are recognized. The control circuit 2 provides the recognition circuit 8 with character pitch designation data up to two digits below the decimal point. Also, the unit of this character pitch designation data is unified to either metric or inch. By doing this, the open weaving circuit only needs to output the character tFJn in either inch or meter. . The recognition result in the recognition circuit 4 is temporarily stored in the response record circuit 5 and sent to the external control device 1. In this external control device j.

The sent recognition results are edited.

〔Effect of the invention〕

Therefore, such OCR can read handwritten characters written at any character pitch.

Furthermore, when printing a character entry frame on a form, it is possible to print a text entry frame with an arbitrary character pitch.
