Abstract

PURPOSE:To execute printing with a higher resolution than the resolution of a character defined in the inside of taking OR of a picture element for constituting an enlarged character and a correcting picture element, and storing it in a character memory for an enlargement. CONSTITUTION:A control device 5 enlarges an internal character 10 stored in an internal character memory 1, by a magnification required by an equipment, and stores this enlarged character 11 in the enlarged character memory 2. Subsequently, a conversion to the character 12 for the enlarged charactor is executed by taking OR of the enlarged character 11 stored in the enlarged character memory 2, and a character 12 for a converted enlarged printing is stored in the character memory 3 for the enlarged printing. Finally, the control device 5 supplies the character 12 for the enlarged printing stored in the character memory 3 for the enlarged printing, to the printing device and prints it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine having an enlarged printing function.

[Conventional technology]

Conventional facsimile machines, when enlarging and printing internal characters, are able to print quantitatively at a fixed magnification rate in the vertical and horizontal directions, despite the low resolution of the internally defined characters. It was vast.

[Problem that the invention seeks to solve]

For this reason, conventional facsimile machines have low resolution for the character size when enlarging and printing.
There was a problem in that printing was performed using an unnatural font.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a facsimile device that is capable of printing at a higher resolution than the internally defined character resolution.

[Means for solving problems]

The principle of the present invention will be explained with reference to FIG. Figure 2 (1
) shows a part of the character stored in the internal character memory, pixels A and B are located diagonally next to each other and both are black.

When this character is enlarged (in this case, enlarged by a factor of 2), both pixels A and B are enlarged by a factor of 2 and become pixels A' and B', respectively, as shown in FIG. 2 (2). Among the pixels of this enlarged character, blue pixels a and b located diagonally next to each other are both black, so a correction pixel C is created that includes the intersection X of these blue pixels a and b. , B, ---1 of the enlarged character and the correction pixel C (FIG. 2 (3)) is printed.

Figure 3 (1) is an example in which the character "A" is printed by simply enlarging it twice as in the conventional method, but when the above-mentioned invention is applied, it is printed with a high resolution as shown in Figure 3 (2). You can see that it is printed.

That is, the facsimile apparatus of the present invention enlarges characters stored in an enlarged character memory, an enlarged printing character memory, and an internal character memory to create an enlarged character, stores this in the enlarged character memory, and Among the pixels constituting the enlarged character, when blue pixels located diagonally next to each other are both black, a black correction pixel containing the intersection of these blue pixels is created, and the pixels constituting the enlarged character are and a control device that calculates the logical sum of the correction pixels and stores this as an enlarged printing character in the enlarged printing character memory.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a facsimile apparatus according to the present invention.

The facsimile apparatus of this embodiment enlarges characters stored in an internal character memory 1, an enlarged character memory 2, a character memory 3 for enlarged printing, and an internal character memory 1 to create enlarged characters, and enlarges the characters. , is stored in the character memory 2, and when blue pixels located diagonally adjacent to each other among the pixels constituting the enlarged character are both black, a black correction pixel containing the intersection of these blue pixels is created. and a control device 5 for calculating the logical sum of the pixels constituting the enlarged character and the correction pixels to create a character for enlarged printing and storing it in a character memory 3 for enlarged printing, and a printing device 4. The operation of this embodiment will be described in order of zero.

The control device M5 enlarges the internal character 10 stored in the internal character memory 1 at a magnification required by the device, and stores this enlarged character 11 in the enlarged character memory 2. 5 is a character 12 for enlarged printing obtained by taking the logical sum of the enlarged character 11 stored in the enlarged character memory 2 and the correction pixels.
The converted enlarged printing character 1
2 is stored in the character memory 3 for enlarged printing. Finally, the control device 5 causes the printing device 4 to supply the enlarged printing character 12 stored in the enlarged printing character memory 3. Then, in response to the control signal 13 from the control device 5, the printing device 4 prints the supplied enlarged printing character 1.
Print 2.

Note that the enlarged printing character memory 2 can also be used in common with the enlarged character memory 2 or the internal character memory 1.

〔Effect of the invention〕

The present invention enlarges a character stored in an internal character memory to create an enlarged character, and when blue pixels located diagonally adjacent to each other among the pixels composing this enlarged character are both black, the blue A black correction pixel centered at the intersection of the pixels is created, and the logical sum of the pixels constituting the enlarged character and the correction pixel is calculated and this is printed as an enlarged print character, so it is defined internally. It is possible to print at a resolution higher than that of Yayarakuta.

Claims (1)

[Claims] In a facsimile machine, an expanded character memory,
An enlarged character is created by enlarging the characters stored in the enlarged printing character memory and the internal character memory, and this is stored in the enlarged character memory, and the pixels constituting the enlarged character are arranged diagonally adjacent to each other. If both pixels located at are black, a black correction pixel containing the intersection of these two pixels is created, and the logical OR of the pixel forming the enlarged character and the correction pixel is performed and this is enlarged and printed. 1. A facsimile apparatus comprising: a control device for storing a character for enlarged printing in the character memory for enlarged printing.
