JPH098960A - Sender information addition system in facsimile equipment - Google Patents

Abstract

PURPOSE: To add sender information to a read original while minimizing loss of image information of the read original without revising the length of the read original. CONSTITUTION: The sender information addition system in the facsimile equipment is provided with a means, in which a sender information font registered in advance in the facsimile equipment is a ternary special pattern consisting of black level picture elements (a), 1t white level picture elements (b) and 2nd white level picture elements (c), the 2nd white level picture elements (c) of the image information pattern of the sender information corresponding to picture elements of the read original are left as they are and only the black picture elements (a) and the 1st white level picture elements (b) are overwritten onto the read original when the image information pattern of the sender information is superimposed on a head of the read original.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sender information adding method in a facsimile apparatus for sending sender information such as a sending date and a sending time to a read original.

[0002]

2. Description of the Related Art Conventionally, in this type of source information addition method, when the source information is added to the read original, whether the image information pattern of the source information is overwritten and added to the beginning of the read original. Or, the image information pattern of the sender information was added to the beginning of the read original.

[0003]

Generally, all the image information is processed as line data in a unit of one line in the main scanning direction. As shown in FIG. 3, the image information pattern d of the source information is completely overwritten on the read document e, and the output document f after the addition of the source information has the complete image of the leading portion of the read document. It had the drawback of being lost.

In the latter process, as shown in FIG. 4, the number of lines in the sub-scanning direction is increased by adding the image information pattern d of the transmission source information to the beginning of the read original e, so that the recording paper is not printed. Since the length is longer than the fixed size, a portion g protruding from the fixed size is generated, and there is a drawback that two sheets of recording paper are output when a cut sheet is used in the receiving device.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and provide a sender information adding system for adding sender information with minimal loss of image information of a read document, waste of paper, and addition of sender information. That is.

[0006]

According to the present invention, in a facsimile apparatus for transmitting source information such as date of transmission and time of transmission to a read document, the image information of the read document is displayed in black and white. Storage means for storing the original image information represented in the memory, and registered sender information in JIS
Source information output means for outputting code information, and the JI
Image information pattern generating means for generating an image information pattern of the sender information from S code information and a font for the sender information registered in advance, and an image for superimposing the image information pattern of the sender information on the head of the read document. There is provided a sender information adding method in a facsimile, which has an information pattern superimposing means and adds the sender information to the read original without damaging the image of the read original.

Further, according to the present invention, the source information font and the image information pattern of the source information are specially represented by three values of black pixels, first white pixels, and second white pixels. A source information addition method in a facsimile characterized by being a pattern can be obtained.

Further, according to the present invention, when the black pixel and the first white pixel are superposed on the read original,
The corresponding pixel of the read original is overwritten and the second
As a white pixel, the corresponding pixel of the read original document is left as it is, so that the sender information adding method in the facsimile can be obtained.

[0009]

1 is an example of a character font for source information according to the present invention, which is represented by three values of a black pixel a, a first white pixel b, and a second white pixel c. When superposed, the black pixel a and the white pixel b are completely overwritten, and the white pixel c leaves the pixel of the read document at the position to be superposed as it is.

When a document is input to the facsimile machine,
The image information of the read document is stored in the memory as original image information represented in black and white. At the same time, the date of origination, the time of origination, the originating telephone number, etc. are output from the calendar information as JIS code information, and the source information font and the JIS code information shown in FIG. An image information pattern is generated. The image information pattern of the transmission source information is the same as that of the transmission source information font.
Of the white pixel b and the second white pixel c.

When the image information pattern of the source information and the read original are superimposed, processing is performed bit by bit in the main scanning direction, and the second white pixel portion of the image information pattern of the source information is shown in FIG. As shown in, the corresponding pixels of the read original appear transparently, and an image in which only the black pixel portion and the first white pixel portion of the image information of the source information are overwritten on the read original is output. Therefore, the image of the read document is not completely lost.

Further, since the black pixels of the source information font are surrounded by the first white pixels, the image of the source information appears even when it overlaps with the black pixel portion of the read original, and Information can be read clearly (see Fig. 2).

[0013]

As described above, according to the transmission source information adding method of the present invention, the transmission source information can be transmitted without damaging the image of the read original as much as possible and without changing the length of the original. There is an effect that it can be added to the read original.
