Abstract

PURPOSE:To improve efficiency for editing read data by hardly generating key input errors. CONSTITUTION:An image extracting part 22 stores a ruled line 12 and a ruled line frame 13 on a form 11 in an image storage part 23 as images. A coordinate extracting part 24 transforms the position of an end point 15 of the ruled line/ ruled line frame to the coordinate code of a display with a left edge 14 of the paper 11 as a reference and stores it in an image position storage part 25. A character identifying part 26 identifies a character on an identifying character object slip and stores its character code in an identified character storage part 27. The coordinate code is extracted from the image position storage part 25, and that image is displayed on a display 31 by an image display part 28. Based on display position identification information previously registered on an identified character position storage part 29, the identified character is displayed at the designated position of that image by an identified character display part 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical character reader, and more particularly to automatic editing control of identification characters of an optical character reader.

[0002]

2. Description of the Related Art In a conventional optical character reader, when an identification character is edited and displayed on a display, the position at which the identification character is displayed and the position of a ruled line or a ruled line frame decorating the identification character are displayed on the display. Key input settings were made based on the coordinates designated in advance, and the identification characters, ruled lines, and ruled line frames were displayed on the display.

[0003]

In the conventional optical character reader, when the identification characters are edited and displayed on the display, the positions of the identification characters and the end points of the ruled lines are set in advance on the display. In addition, since it was set finely by key input, it is easy to make a mistake in editing the identification character due to a key input error or a setting error.

[0004]

An optical character reader according to the present invention comprises a photoelectric conversion means for photoelectrically converting a ruled line or a ruled line frame printed on an arbitrary sheet of paper and a ruled line or a ruled line frame from the left end of the sheet. Coordinate extraction means for extracting the position to the end point, storage means for storing the extracted position information, character identification means for identifying the characters entered in the character identification form, and display position identification on the display registered in advance It is characterized by having a display display means for displaying a ruled line, a ruled line frame and an identification character on a display based on information.

[0005]

Embodiments of the present invention will now be described with reference to the drawings.

Referring to FIG. 1, in one embodiment of the present invention, an image extraction unit 22 in a photoelectric conversion unit 21 is used to read an arbitrary sheet 11 before reading a character on an identification character target form.
Is scanned and the ruled lines 12 and the ruled line frame 13 on the paper 11 are stored in the image storage unit 23 as images. Coordinate extraction unit 24
Converts the positions of the ruled lines 12 and the ruled line frame 13 of the image into the coordinate code of the display based on the left end 14 of the paper 11, and the image position storage unit 2
Store in 5.

Next, the character identification unit 26 identifies the character on the identification character target form and stores the character code in the identification character storage unit 27.

After the characters entered in one identification character form have been identified, the coordinate code of the image is extracted from the image position storage unit 25 and the image display unit 28 displays the image on the display 31. Next, the display position identification information registered in advance in the identification character display position storage unit 29 is extracted, and the identification character display unit 30 displays the identification character at the designated position of the image.

[0009]

As described above, in the present invention, when the read data is displayed on the display, the read data and the display positions of the ruled lines and the ruled line frame are automatically set, so that a key input error occurs. To improve the efficiency of editing read data.
