Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an OCR character printing system, and more particularly to an OCR character printing system for automatically converting OCR characters such as barcodes from ordinary character data to print OCR characters such as barcodes. Regarding the system.

Conventional technology Conventionally, when an OCR character is printed using a character output device, a method of re-editing text data is mainly used as a method of converting a specific character in the text data into the OCR character. The disadvantages are the complicated re-editing routine, maintainability of OCR character data, and slow processing speed.

Separately from this, for example, as disclosed in Japanese Patent Laid-Open No. 60-163154, there is provided means for converting the input data inputted from the keyboard into a bar code, and the bar code obtained by the conversion means is stored in a card. A word processor that is adapted to record is known. In addition, JP-A-59-1320
As disclosed in Japanese Patent No. 30, a document creating apparatus is known in which it is easy to associate a print image of a document including a modified character (or a character string) with the display screen content.

However, considering these technologies in combination,
There is no idea that data should be unified and the amount of data should be reduced by combining character data and OCR character data and using both of them as the case may be.

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the problems as described above in a conventional OCR character printing system, to have a combination of character data and OCR character data, and to provide an OCR character The present invention is to provide an OCR character printing system capable of unifying data and reducing the amount of data by automatically converting and printing from normal character data, and selectively using both depending on the case.

Configuration The above-mentioned object of the present invention has a host computer and an image processing terminal connected thereto, and uses a character output device.
In the OCR character printing system that prints OCR characters, on the image processing terminal side, the data to be OCR printed in the standard document is added with a code indicating that and transmitted to the host computer. The database is searched according to the information, and the corresponding OCR character data, the flag indicating whether to change to the OCR character at the time of printing, and the data corresponding to the coordinates indicating the print character are returned, and the image processing terminal side returns the returned data. When the normal character data exists at the print position, the normal character data is output at the time of display and the OCR character is output at the time of printing based on the data. This is achieved by the OCR character printing system characterized by giving priority to the display output by.

In the present invention, a document is created on the terminal side capable of performing image processing. This document has a blank space for the character string sent from the host. An index key to be transmitted to the host as a text data internal code (a special code not displayed on the screen) is contained in this blank part. When this index key is sent to the host, the host side searches the database based on the received index key and sends the obtained data to the terminal.

The contents of this data are as follows: (1) Character string corresponding to the index key that fills the blank of the terminal document (2) Flag indicating whether or not to convert each character into OCR characters (3) Absolute vertical and horizontal OCR characters for each character Includes specified values (coordinates).

When the terminal receives this data, it inserts the character string (1) into the corresponding position (blank part) of the data. When this document is displayed, only the characters are displayed, and when printing, the characters with the OCR character designation (the flag of 2) are replaced with the OCR characters,
Printing is performed by adjusting the vertical and horizontal positions according to the coordinates of (3).

Hereinafter, the configuration of the present invention will be described in more detail based on examples. In the embodiment described below, a printing operation of a fixed form document based on an operator's input in a system including a host computer and an image processing terminal connected thereto will be described.

The host computer stores data corresponding to the standard document in a storage device attached to the host computer. As described above, this data is composed of a character string that fills the blank of the terminal document corresponding to the index key, a flag indicating whether or not to convert each character into an OCR character, and the coordinates of the OCR character for each character.

The index key exists in the text data in the fixed form document as a special key that can be distinguished from the character data. For example, a code that is not used as character data, ES
It exists with the C code added to the beginning and ending.

<Character data><ESC><Indexkey><ESC>
<Character data> (1) In this case, since the index key is not recognized as character data, it is not displayed on the screen or printed at the time of printing. The index key is the record number of the OCR character data database record that accompanies the host computer.
It corresponds to.

FIG. 2 is a diagram showing an example of a display screen of the above-mentioned fixed form document,
FIG. 1 is an operation flowchart of processing performed by the terminal and the host computer based on the input from the screen of the fixed form document. As shown in FIG. 2, a character string (×
There is a blank part surrounded by a frame between the marks. The blank area contains the index key.

When the terminal side searches for this index key and sends it to the host in the form of (1) above (steps 11 and 12),
The host side searches the database based on the received index key (steps 21 and 22) and transmits the obtained data to the terminal (step 23). The format of the data at this time is as follows: <Character data><ESC><OCR character data><ESC><Characterdata> (2), and the data is documented based on this data on the terminal side. Merge in (steps 13 and 14).

Next, the terminal displays it as a normal character when displaying it with the flag that indicates whether to print it in the above OCR character data (steps 15 and 16), and when printing it displays it as an OCR character. Printing is performed (steps 15 and 17).

OCR corresponding to the index key by the above process
The character is obtained. In the OCR character data, O
There is a flag that indicates whether or not to display / print as CR characters, which makes it easy to print / display documents with and without OCR characters.

According to the above-described embodiment, there is an effect that a character code that is difficult for human beings to recognize, such as an OCR character, can be displayed and confirmed as a normal character. Also, in one document,
Since both normal characters and OCR characters can be registered as one character, it is possible to achieve a reduction in the amount of data compared to the case of using two documents, a conventional normal character document and an OCR character document. You can

If normal character data exists on the X and Y coordinates of the OCR character display, by giving priority to the OCR character, the normal character is displayed at the place where you want to display the OCR character when the OCR character is not displayed. It becomes possible to do.

That is, if you choose to display in OCR characters,
The effect is that you can always check the presence or absence of OCR characters on the display screen at a glance.If you choose not to display OCR characters, you can display only normal characters to see if there are OCR characters. If you don't need to check
Since the display screen configuration includes only normal characters, it is possible to obtain the effect that the display content can be confirmed reliably and easily.

Needless to say, the above-mentioned embodiment is shown as an example, and the present invention should not be limited to this.

Effects As described above, according to the present invention, in the OCR character printing system that has the host computer and the image processing terminal connected to the host computer and prints the OCR characters using the character output device, the image processing terminal side Then, OCR in the standard document
A code indicating that fact is added to the data to be printed and sent to the host computer, and the host computer searches the database according to this information, and the corresponding OCR character data, whether or not to change to the OCR character at the time of printing The data corresponding to the flag indicating and the coordinates indicating the print position are returned,
On the image processing terminal side, based on the returned data, normal characters are output at the time of display and OCR characters are output at the time of printing, so data is unified and the amount of data is reduced. In addition to enabling, OCR characters are automatically converted from ordinary character data and printed.
This has the remarkable effect of realizing an OCR character printing system.
