Abstract

PURPOSE:To make all of the characters read from a slip as an output characters by designting the number of output characters apart from the character frame number that shown the number of read characters. CONSTITUTION:The slip 11 in which characters are written is transferred to a photoelectric conversion part 13 by a paper feeding control part 12. In the photoelectric conversion part 13, the ship is optically scanned, and the characters are converted to binarization patterns. The binarization patterns are segmented into the unit of one character by a character segmenting part 14, and collated with a standard pattern in a dictionary memory 16 by a character recognition part 15, and thus the character recognition is executed. The result of the reading by the part 15 is outputted to an external device via a flexible disk device 20, or a communication line 21 and a channel 22. The numbers of character frames of the characters 40 on the slip and the output characters 41 are designated through a keyboard 18 respectively.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an optical character reading device, and in particular, the reading result when voiced/semi-voiced katakana characters are written in a frame is displayed in two frames. The present invention relates to an optical character reading device suitable for.

[Conventional technology]

In conventional optical character reading devices, when reading a form in which voiced and semi-voiced katakana characters are written in one frame, the reading result is configured to display the voiced and semi-voiced katakana characters in two frames. That is, as shown in FIG. 7, the characters 30 entered on the form are voiced/semi-voiced katakana characters in one frame, but the output characters 31 representing the reading results are divided into katakana, voiced/semi-voiced sounds. are displayed in two frames.

Incidentally, as an optical character reading device capable of reading a form in which the above-mentioned voiced and semi-voiced katakana characters are written in one frame, the one disclosed in Japanese Patent Application Laid-Open No. 58-97783 is known.

[Problem that the invention seeks to solve]

In conventional optical character reading devices, the number of output characters indicating the reading result is configured to match the number of reading frames of the form, so as shown in Figure 6, there is a situation where all the read characters are not displayed. was occurring. In FIG. 6, the last character "ji" is not displayed as the output character 31.

The present invention was made in view of the problems of the prior art described above, and reads the voiced and half-voiced katakana characters written in one character frame without writing only the voiced and half-voiced marks in one character frame. In an optical character reading device that outputs the reading results to the outside via an external device such as a flexible disk device (displayed on a CRT, or a communication line or channel), it is possible to convert all read characters into output characters. The purpose is to provide an optical character reading device.

[Means for solving problems]

The optical character reading device of the present invention includes a first means for specifying the number of character frames indicating the number of characters to be read on a form, and a second means for specifying the number of output characters output from the optical character reading device. It is characterized by the presence of

[Effect]

According to the present invention, it is possible to specify the number of output characters separately from the number of character frames indicating the number of read characters, so that it is possible to provide an optical character reading device that can output all characters read from a form. Can be done.

[Example] Hereinafter, the present invention will be described in more detail with reference to Examples shown in the accompanying drawings.

FIG. 2 is a block diagram of an optical character reading device showing one embodiment of the present invention. The form 11 on which characters have been written is sent to the photoelectric conversion section 13 by the paper feed control section 12 . The photoelectric conversion unit 13 optically scans the form and converts the characters into a binary pattern. The binarized pattern is cut out character by character by the character cutting section 14, and the character recognition section 15 performs character recognition by comparing it with a standard button in the dictionary memory 16. The reading result read by the character recognition unit 15 is (
The data may be displayed on the CRT 19 or output to an external device via the flexible disk device 20 or the communication line 21 or channel 22. These flows are controlled by the control section 17. Further, numeral 18 in the figure indicates a keyboard.

FIG. 1 is a diagram showing an example of input characters 40 and output characters 41 of a form according to the present invention. In this case, the number of character frames for reading is specified as eight, and the number of output characters is specified as ten using the keyboard 18 shown in FIG.

As a result, all characters 40 written on the form are displayed as output characters 41. That is, since "ga" and "ji" in the entered characters 40 are each displayed in two frames, it is sufficient to set the number of output characters in excess of that amount.

FIG. 3 is a diagram showing another example of input characters and output characters of a form according to the present invention. In this case, the number of character frames for reading is specified as 10 using the keyboard 18, and the number of output characters is the same (specifying 10 results in output character 51. In this case, the last two characters of input character 50 are not displayed. become.

Further, if the number of output characters and numbers is specified as 20 using the keyboard 18, an output character 52 is obtained. In this case, the last eight characters of output characters 52 are blank.

Furthermore, if the number of output characters is specified as 10 using the keyboard 18, the reading result will exceed the number of output characters. In this case, it is conceivable to output an abnormal digit code "!" indicating that the frame has been exceeded, as shown in the output character 53, by a command from the keyboard 18, for example. The abnormal digit code can be any code, and all digits may be made into an abnormal digit code to notify that the data in the field is suspicious.

FIG. 4 is a diagram showing a specific example of the form 11 shown in FIG. 1. As shown in the figure, when specifying the reading field of the form 11, a vertical position 61, a start position 62, and the number of character frames 63 are specified as the position of the character frame to be read. The number of character frames 63 can also be determined by specifying the end position 64. Also, at this time, the reading type, whether voiced or semi-voiced characters are filled in the box, is specified at the same time. Furthermore, the number of output characters is also specified at the same time.

The above specification contents can be specified for each field when complex fields are defined in the form 11.

Also, to specify the number of output characters, use the ratio to the number of character frames,
It is also possible to perform as follows: l:1.5.1:2.

FIG. 5 is a diagram showing an example of a format on the CRT 19 for each of the above specifications. As shown, vertical position 61
At the same time, the reading type 65 indicating whether or not the voiced sound/half voiced sound character is to be filled in the box is designated, and the number of output characters 66 is designated.

FIG. 6 shows an example of a field table 70 created for each field on the form 11 according to the specified contents.

By performing the above specification processing, the character cutting unit 14 and character recognition unit 15 shown in FIG. Performs cutout recognition. The control unit 17 outputs the reading results received from the character recognition unit 15 according to the number of output characters 66.

〔Effect of the invention〕

As detailed above, according to the present invention, the number of output characters can be arbitrarily specified in addition to the number of frames, so if you do not want to change from the conventional output format, you can specify the same number as the number of frames, and
This has the advantage of being able to be specified according to the purpose, such as when writing a half-voiced sound in one frame and outputting more characters than the number of frames, it is only necessary to specify a value larger than the number of frames.
