Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character reading device that can also read special characters that are different in size from ordinary characters, such as lowercase letters, voiced marks, and half-voiced marks.

FIG. 1 is a diagram for explaining a conventional device of this kind. In the figure, 1 and 2 are examples of character pattern strings recorded on a reading form. 4 is the same pattern.

In conventional devices of this type, special characters were distinguished by the absolute size of the characters, so example 1 of the character pattern string above was read as ``bus'' and example 2 of the character pattern string was read as ``Harris.'' The drawback was that it was impossible to separate them.

This invention is characterized by distinguishing between ordinary characters and special characters by examining the difference in size between adjacent characters5, and its purpose is to prevent misreading.

FIG. 2 is a diagram showing an embodiment of the present invention, in which 5 is a detection means for detecting the size of a character pattern, and 6 is a memory for storing the size of the character pattern detected by the detection means 5. Means 1 is a comparison means for comparing the size of the character pattern detected by the detection means and the size of the character pattern stored in the storage means, and 8 is a data line from the detection means to the comparison means. , 9 is a data line from the detection means to the storage means, 10 is a data line from the storage means to the comparison means, and 11 is an output means from the comparison means. The size of the character pattern detected by the detection means 5 is sent to the comparison means 20 stages □ and the storage means 6 through the data line 819.

At the same time, the size of the character pattern stored in the storage means is sent to the comparison means T through the data line 10. The comparing means □ determines whether the detected character pattern is a special character by determining the difference in size 25 between the characters input through the data line 8110. Because it is structured like this, special characters.

Since it can be distinguished by looking at the difference in size from the ``Nari'' character pattern, it is possible to prevent erroneous recognition with ordinary characters by 30%. Note that although the case of a voiced mark has been described above as an example of a special character, the present invention is not limited to this, and may be used to distinguish other special characters, for example, lowercase letters such as gear, kyyu, and kiyo.

35 As mentioned above, according to the present invention, general characters and special characters are distinguished by checking the difference in the size of Tonawagoura characters, so errors in character strings written entirely in small characters can be avoided. It has the advantage of preventing recognition.

[Brief explanation of drawings]

Figure 1 is a diagram showing an example of a character string to explain a conventional device of this type. FIG. 2 is a diagram showing an embodiment of the invention. 1 in the figure is an example of a character string written as "bus". 2 is an example of a character string written as "Harris", and 3 is a special character, a voiced mark. 4 is the same pattern as 3 above, but a character pattern of "ri", 5 is a detection means for detecting the size of the character pattern,
6 is a storage means 67 is a comparison circuit, and 8, 9, and 10 are data lines. 11 is the output.

Claims (1)

[Claims] 1. In a character reading device that also reads special characters that are different in size from ordinary characters, such as lowercase letters, voiced marks, and half-voiced marks, there is a detection means for detecting the character string written on the reading form and the size of the characters, and the above-mentioned detection means. storage means for storing the size of the characters detected by the detection means, and comparison means for comparing the size of the characters detected by the detection means with the size of the characters stored in the storage means, A character reading device configured to be able to distinguish between general characters and the special characters by determining the difference in size between adjacent characters using the comparison means.
