Abstract

PURPOSE:To darw the attention of a reception side by transmitting main-scanning-directional data at a mark part provided at the left edge of an original while performing black-and-white inversion. CONSTITUTION:At the left edge of an original 1, a black mark is provided and when main-scanning-directional data at this part is processed by run-length encoding, the run length of white is repleaced by run-length encoding of black and the run length of black is replaced by run-length encoding of white. Then, a main-scanning-direction part marked at the left edge of the original is inverted with regard to black and white, and recorded.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile apparatus that utilizes a conventional skip function to reverse the main scanning direction line marked at the left end of a document.

The closest thing to invention is the distinction between red and black.

In addition, the facsimile IJ device has the function of marking important parts by printing in red and black.

There it is.

However, this method is expensive and cannot be easily added to a conventional facsimile machine. However, in this case, the conventional 11° skip function can be used as is.

By changing the software (microcomputer-mounted facsimile machine), important parts of the document can be easily inverted and recorded.

The purpose of the present invention is to solve the above-mentioned complexity of the prior art,
It refers to software technology that enables immediate response to needs.

Using the conventional mark skip function, the 111-minute black part at the left edge of the document specified for mark skipping is detected when encoding the line in the main scanning line direction, and the run length of the edges beyond that is detected. is transmitted with black and white reversed.

This method can be easily implemented by simply adding software processing on the transmitting side. 1. As shown in Figure 1, by adding a black mark to the left edge of the document 1, that part was conventionally used as a skin.

However, I did not allow it to be recorded.

For example, in the case of 84 machines, main 1. (If there is a black run length specified within a certain bit from the first bit of 2048 bits of data for one line in the scanning line direction, the white run length is the same as the black run length for the subsequent run lengths.) For run-length encoding, replace black run-length 5 with white run-length encoding.

By doing so, the portion in the main scanning direction marked at the left end of the document is inverted in black and white to form the recording surface 2 in FIG.

This can be provided at a low cost by modifying the software (ROM) of a conventional facsimile machine.

Claims (1)

[Claims] 1. Use the skip function used in FAX.
A black-and-white reversal recording method uses a specific carrier sheet or uses the skip mark method of conventional 5 as is, and inverts the data in the main scanning direction of the marked portion to draw the attention of the receiving side.
