Abstract

PURPOSE:To eliminate the need for an optical mark read head by recognizing the numeral zero of a mark field on a document as the absence of a mark and the numeral zero smeared as the presence of a mark. CONSTITUTION:A printing type numeral '0' readable by an OCR is printed or preprinted in a mark field 2. For example, captions 21, 22 and 23 show a printing type numeral '0' respectively, the captions 21, 23 indicate the absence of a mark and the caption 22 indicates the presence of a mark, which is realized by smearing away the inside of '0' by marking personnel with a writing tool. A mark recognition means recognizes the part recognized as the absence of a mark and the part recognized illegible or other than '0' code as the presence of a mark to provide a mark reading function without preparing a special mark-exclusive device.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to optical mark reading Jl! ! Regarding the 290,000 type, it is particularly concerned with the method of reading the L mark by using the Gengaku letter cyst detection device.

2. Description of the Related Art Conventionally, this type of mark reading system has generally used an optical mark reading head dedicated to reading marks.

However, in many cases, marks and characters are written on documents together, and a character reading device (hereinafter referred to as OCR) must be equipped with an optical mark reading head, which has the disadvantage of making it more complicated. Rarely.

Problems to be Solved by the Invention The purpose of the present invention is to address the above-mentioned drawbacks, namely, to solve the problem of having to install an entire optical mark reading head in addition to the OCR character recognition mechanism for forms that have both marks and characters. The object of the present invention is to provide a mark reading method that solves the problems.

In order to solve the above-mentioned problems, the present invention has an objective of solving the above-mentioned problems.In OCR, which is an all-optical reading system that includes at least the number zero, when the number zero is recognized, there is no mark, If a number other than zero is recognized, a mark recognition means is provided to mark the mark, and a means is adopted in which the number zero is printed on the form in advance and every other number is painted over as appropriate to form a mark. be.

Operation Since the present invention is configured as described above, the number zero in the mark field on the form is recognized as no mark, the painted number zero is recognized as marked, and the character field is recognized as the conventional character reading system. It can be performed.

Example Next, embodiments of the present invention will be described with reference to all the drawings.

In addition to the conventional character reading function, the character reading session B (ockL) according to an embodiment of the present invention has a mark recognition function in which, in addition to the conventional character reading function, there is no mark when the number zero is recognized, and there is a mark when the number other than zero is recognized. have the means.

The form in this example? In Figure 1, 1 indicates a form, 2 indicates a mark field, and OCR
We have pre-printed 10# printable numbers that can be read on the computer.

Figure 2 is an enlarged view of mark field 2, 21.2
2.23 indicates the printed numeral "'0#", 21.
23 indicates no mark entry, 22 indicates mark entry person υ,
The person filling in the mark filled in the inside of the 60# with a writing instrument.

When OCR recognizes mark field 2 of form 1 as a type field, OCR recognizes the unfilled printed number ``''0'' as '0'', and the unfilled printed digit ``''0''.
It is a well-known fact that a recognition result code other than '0' is readable or 'O' is transmitted.Therefore, in a place recognized as '0#' by the mark recognition means, there is no mark written, or it is unreadable or '10'. By determining that the person who wrote the mark 9 is in a location recognized by a code other than #, the mark reading function 9 can be provided without the need for a special mark-dedicated mechanism.

That is, in the case of a character field, it is possible to read both characters and marks by using the conventional method, and in the case of a mark field, by using a mark recognition means.

Effects of the Invention As explained above, according to the present invention, printed numbers that can be read by OCR are added to the mark field on the form.
0" is printed or preprinted, and when marked p, '
0", OCR recognizes all of the above fields, and when the recognition result is @0", mark is not entered, and when the recognition result is other than 0", mark entry is ND. By providing this, it is possible to read marks without providing a special mark reading mechanism.

Claims (1)

[Claims] In a character reading device that can optically read characters including at least the number zero, a mark recognition means is provided which recognizes that there is no mark when the number zero is recognized, and that there is a mark when the number other than zero is recognized. This mark reading method is characterized in that the presence or absence of a mark is determined based on whether or not the number zero is filled in on the form by using a method of printing the number zero in advance and filling it out as appropriate.
