Abstract

PROBLEM TO BE SOLVED: To provide a facsimile communication method, which requires only a half of conventional communication time at the time of communication in a normal mode by providing two picture modes, reading an original through normal scanning and transmitting it to an opposite machine type as picture data of fine scanning. SOLUTION: The original is set, a transmission mode is selected and the transmission mode of a FAX mode and the like is selected. Since 'Is it normal mode?' is displayed on a liquid crystal display, a 'NO' key is depressed. Then, 'Is it high speed normal mode?' is displayed. When 'YES' key is depressed, a transmitter-side reads the original in normal scanning and it is transmitted to an opposite machine after picture data in fine scanning is transmitted to the opposite machine. Then, the opposite machine restores transmission data in normal scanning at the scanning time of the fine node. Thus, scanning time becomes about half the normal time and communication terminates in time half the conventional normal picture transmission time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a G3 facsimile communication method.

[0002]

2. Description of the Related Art The G3 facsimile currently most commercially available has a normal image mode of normal mode (sub-scan 3.85 Line / mm).
And fine mode (the sub-scan is 7.7 Li).
ne / mm) is standard equipment.

In this type of G3 facsimile, the method of minimizing the communication time is for the manufacturer of the G3 facsimile to communicate in its own mode. This communication method may be that of the same manufacturer, but there is a drawback that communication cannot be realized between different models. Therefore, in practice, normal communication that can support any model is G
This is the shortest communication method when 3 facsimiles are used.

By the way, most of the G3 facsimiles are models having a minimum scanning line time capability in the fine mode which is ½ of that in the normal mode.
These models are fine mode (7.7 Line / m
m), the minimum step of the drive motor is also 7.7 Line / mm. Therefore, when the normal mode is selected and transmitted using such a model, as shown in FIG. 3, the image is read in the normal mode (3.85 Line / mm) and one line is transmitted. Then, since the receiving side cannot print in the normal mode, the same line data is fined (7.
7 lines / mm) step, 2 lines are printed and restored as a normal image, and in normal reception, a scanning line time which is twice as long as in fine reception is required.

An object of the present invention is to provide a facsimile in which two kinds of image modes, a normal mode and a fine mode, are prepared and which has a minimum scanning line time capability which is about one half of the normal mode when the fine mode is selected. It aims to provide a facsimile communication method that is compatible with any type of facsimile regardless of manufacturer, and is designed so that communication time in normal mode requires half the communication time of conventional ones.

[0006]

In order to achieve the above-mentioned object, the present invention prepares two kinds of image modes, a normal mode and a fine mode. High speed normal mode can be selected when normal mode is selected between facsimiles with minimum scanning line time capability, in which case the original is read by normal scanning and transmitted as image data by fine scanning to the partner model. It is characterized by that.

Further, according to the present invention, even when the high-speed normal mode is selected, if the mode is canceled, the original can be read by normal scanning and can be transmitted to the partner model as image data in normal scanning.

[0008]

According to the present invention, since the normal scanning data is printed in the fine mode, the restoration is completed in about half the time and space as compared with the conventional one.

According to the second aspect of the present invention, the normal scanning data is printed in two fine lines to restore a normal image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a communication method according to the present invention, in which a facsimile on the transmission side is normally scanned (3.85).
The original is read in Line / mm), and this is transmitted to the facsimile on the receiving side as image data in fine scanning. Then, the receiving side receives the data on the transmitter side in the normal scanning as the image data in the fine scanning and restores the data in the scanning line time in the fine mode.

FIG. 3 is a flow chart showing the operating procedure at that time. A document is set on the platen, a transmission mode is selected, and a transmission mode such as TEL mode or FAX mode is selected. Then, when the FAX number of the other machine is input, for example, "Start button?" Is displayed on the liquid crystal display, so the Yes button is pressed. Then, "Normal mode?" Is displayed. If the No button is pressed here, the process returns to the step of displaying "Start button?" Again. When the Yes button is pressed, "High-speed normal mode?" Is displayed this time, and the communication method according to the invention of the present application described later is performed.

Next, when the No button is pressed when the "Normal mode?" Is displayed, the next "Fine mode?" Is asked. When the No button is pressed further, the FAX control signal is issued. Subscan 15.4Lin
Scan the original at e / mm and send it to the recipient. When the transmission is completed, a control signal to that effect is transmitted and then the communication is terminated.

As described above, when the Yes button is pressed when the "high speed normal mode?" Is displayed, after the image data of the fine scan of the sub-scanning 7.7 Line / mm is transmitted to the partner machine, At the transmitter side, 3.8
A document is read by normal scanning of 5 Line / mm and transmitted to the other device. Then, the other machine
Since the normal scan transmission data of 3.85 Line / mm is restored in the fine mode scan time, the scan line time is half that in the normal mode, which is about half the conventional normal image transmission time. Communication will end in time. When the reading of the document is completed, a message indicating that the transmission is completed is made, and the communication is completed.

Next, when the "High-speed normal mode?" Is displayed, if the No button is pressed, the fact that the image data is normal scanning (3.85 Line / mm) is transmitted to the other device, and normal scanning is performed. Will read the original and send it to the other device. In this case, as described above, the receiver side is in the normal mode (3.85 Li
Since it is not possible to print at the ne / mm), two lines of the same line data are printed at the fine step (7.7 Line / mm) to restore a normal image.

[0015]

As described in detail above, the present invention is
When the high speed normal mode is selected, the original is scanned by the normal scanning (3.85 Line / mm) on the transmitter side, and the fine scanning (7.7L) is sent to the other device to start image transmission.
Since the other device restores the normal scanning image with the scanning line time in the fine mode, the scanning line time in the normal mode is about half the scanning line time. Therefore, the communication is simply completed in half the transmission time compared to the conventional normal image transmission time, and the communication time can be shortened.

Further, since the transmission data of the normal scanning is restored and printed in the fine mode, it is not necessary to print the same data in two lines, so that the recording paper on the receiver side can be saved. Is.

Next, if the No button is pressed when "High speed normal mode?" Is displayed, conventionally known normal communication can be performed.
