Abstract

(57) Abstract: In a form having a dropout color portion to be read by an optical device, the color limitation of the dropout color portion is eliminated, and the problem that the color is thin and difficult to see is solved. SOLUTION: A character 1 is formed by using a thermochromic ink having a property of being reduced in color by heat from a light source of an optical device for reading a form 10.
1, the dropout color portion such as the character frame 12 and the ruled line 13 is printed. Since the color of the dropout color part is reduced before passing through the sensor part, there are no restrictions on the color and density of printing, and it is possible to print in a color that is much easier to see than the dropout color ink.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a FAX-OCR form, an OCR / OMR form, and a form for a device for optically recognizing characters, symbols, marks, bar codes, etc. other than a dropout color portion. It is about.
The dropout color means a color that cannot be read by an optical device such as a FAX, and is generally used when printing characters, character frames, ruled lines, etc. in the area to be read. Is.

[0002]

Conventionally, for example, FAX-
The dropout color portion of the OCR form is printed using dropout color ink having a wavelength near the wavelength of the sensor. Further, with respect to the dropout color ink, each company is eagerly researching the color, the visibility and the like. However, the dropout color ink currently used in FAX-OCR forms has a light source wavelength of around 540 to 570 nm in the sensor part of a normal fax machine, and is generally green-based or blue-based. If you do not lower it, you will not be able to completely drop out, so there is the disadvantage that the characters, etc. are very difficult to see. Also, with regard to forms such as bank transfer request forms that are absolutely desired to be printed in red, we operate with a special fax with a different light source, but fax costs considerable money when replacing . In addition, since such a fax machine uses a light source that drops out red ink, it cannot take an imprint.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the dropout collar portion of a document having a dropout collar portion read by an optical device. The purpose of the present invention is to provide a form that solves the problem that colors are difficult to see because the colors are not restricted.

[0004]

In order to achieve the above object, the present invention relates to a form having a dropout color portion, which is a thermochromic material having a property of being discolored by heat from a light source of an optical device for reading the form. It is characterized in that the dropout color portion is printed using ink.
Here, the color reduction of a thermochromic ink refers to a change from colored to colorless, or from colored to dropout color (concentration sufficient to drop out with an optical device used for reading), and the change is reversible and irreversible. It can be either target.

[0005]

Next, an embodiment of the present invention will be described.

FIG. 1 shows a FAX-OCR form as a transfer request form used by a financial institution. This type of FAX-OCR form 10 has a character 11 and a character frame 1.
2. The ruled lines 13 and the like are the dropout color portions, which are usually printed in the inconspicuous color dropout colors such as green and blue. However, in the present embodiment, these dropout color portions are Print in a noticeable color (red, black, etc.) using a thermochromic ink that has the property of being discolored by the heat of the fax light source. If you fill in the required fields in the transfer request form in which the dropout color part is printed using this thermochromic ink and send it by fax to the office centralized center over a normal fax, the light source of the fax before passing through the sensor part Due to the heat from the thermochromic ink, the color of the thermochromic ink drops and drops out, and only the handwritten characters can be read.

[0007] FAX-OCR forms include, in addition to the above-mentioned transfer request form, order forms and daily reports used for distribution, reply forms for communication correction, etc. Can be used.

FIG. 2 shows an OCR / OMR form used as a questionnaire postcard. Usually, in the OCR / OMR form 20 of this type, the character 21, the mark portion 22 and the like are the dropout color portion. OC
Compared to FAX-OCR, R / OMR has more sensors and more dropout color inks can be used, but the density is limited, and the appearance is inevitably thin. In this embodiment, the dropout collar portion is
Printing is performed in a conspicuous color (red, black, etc.) using a thermochromic ink that has the property of being discolored by heat from the light source of OCR / OMR. Respondents to the questionnaire fill in the selected mark portion of the OCR / OMR form 20 printed with the dropout color portion with this thermochromic ink with a pencil and send it to the questionnaire source. Postcards sent by the questionnaire O
When applied to CR / OMR, the thermochromic ink is reduced in color by the heat from the light source of OCR / OMR and drops out, so that only the marked portion can be read.

As OCR / OMR forms, there are various answer sheets including the above-mentioned questionnaire postcards,
The present invention can be applied to any of them.

Further, the application to the bar code form is also OCR /
It can be developed in the same way as the OMR form. Other, characters, symbols,
It can be applied to general forms for optical devices that optically recognize marks, barcodes, etc.

[0011]

As described above, the form of the present invention is
Since the dropout color part is printed using thermochromic ink that has the property of being discolored by the heat from the light source of the optical device that reads the form, the dropout color part is exposed to heat before passing through the sensor part of the optical device. Since the colors are reduced, there are no restrictions on the colors and densities of printing, and printing can be performed with colors that are much easier to see than with dropout color inks. In the case of FAX-OCR forms,
By using red and black thermochromic ink, it is possible to read the form with an existing fax without using a special fax.
