Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a facsimile system.

(B) Conventional technology In a facsimile machine, a control signal is transmitted and received before and after transmission of image information data, but it takes several seconds before the transmission and reception of the control signal is started. Therefore, when transmitting a plurality of originals, there is a problem in that the control signal transmission / reception time for each sheet is considerably long, and the communication time is long, so that the communication fee is increased.

Therefore, as shown in Japanese Patent Laid-Open No. 57-3470, a mode is provided in which transmission / reception of control signals is omitted, and control signals are transmitted / received only at the beginning when transmitting a plurality of originals, and control signals for each original in the middle A technique has been proposed in which the communication time is shortened by omitting the transfer of information.

This method can significantly reduce the communication time when the number of originals to be sent is large, but in this case it is necessary to send all originals in the same transmission mode. In this case, it is necessary to transmit in the mode for transmitting and receiving the control signal, and there is a problem that the communication time cannot be shortened.

(C) Problems to be Solved by the Invention The present invention has been made to solve the above problems.
It is an object of the present invention to provide a facsimile system capable of omitting transmission / reception of a control signal even when transmitting a plurality of originals by changing the transmission mode on the way.

(D) Means for Solving Problems The present invention is a means for inputting transmission mode data of a transmission original to a transmission side, a means for storing the input data, and a means for transmitting the input data to the reception side. And means for transmitting the read original data based on the transmission mode data stored in the storage means, while means for storing the transmitted transmission mode data on the receiving side and the stored transmission mode data It is constituted by means for receiving and recording based on the above.

(E) Operation Due to the configuration of the present invention as described above, when transmitting a plurality of originals, data for instructing the transmission mode is input and stored for each original in advance, and also transmitted to the receiving side for storage. With this setting, the transmission / reception process is performed based on the stored transmission mode data, so that the transmission / reception of the control signal during transmission can be omitted, and the communication time can be shortened.

Incidentally, FIG. 1 (a) shows a facsimile machine on the transmitting side, and FIG. 1 (b) shows a facsimile machine on the receiving side.

 Next, the operation of the present invention having such a configuration will be described.

First, when one document is transmitted when the communication mode key of the keyboard (6) is set to the normal mode, as shown in FIG. 2, the transmission side is dialed to the reception side to establish a line connection. Phase B decided by the standard when carried out
After the control signal (a) is transmitted and received, the document data read by the reading section (3) is transmitted, and at the end of the transmission, the control signal (b) is transmitted and received in the phase E to connect the line. Disconnect and end transmission.

Next, a case where, for example, two originals are transmitted in different modes will be described.

In this case, the transmission of the first original is performed in the same manner as described above, and during reading and transmission of the first original, the mode data of the second original is displayed on the keyboard (6) as shown in FIG. When input, for example, when the fine mode in which the sub-scanning speed is halved of the standard is selected, the control circuit (1) that has detected the mode change causes the control circuit (1) of the first document to read When the transmission is completed, the control signal (a) in phase B is sent and received again to instruct the receiving side to change the mode.
The second original is read and transmission is performed in a mode different from that of the first original. When the transmission of the second document is completed, the control signal (b) is given and received, and the transmission is completed.

Although the above explanation was for the case of transmitting two originals,
The transmission can be performed in the same manner even when the number of sheets is larger.

Next, regarding the operation when the communication mode key of the keyboard (6) is set to the omission / reception mode of the control signal, the fourth operation will be described.
A description will be given based on the figure.

The case of transmitting three originals will now be described. Before transmission, the mode data input state is set with the keyboard (6), and the transmission mode data for each original is displayed according to the input instructions sequentially displayed on the display (7). Enter. The control circuit (1) that takes in the input data writes and stores the data for each document in a predetermined area in the data memory (5). When the transmission mode data of all the originals have been input in this way, the originals to be transmitted are set in the reading unit (3) and transmission is started in the same manner as described above, but the first control signal (a) is sent and received. Control circuit (1) is NS
The transmission mode data stored in the data memory (5) is transmitted to the reception side by the S signal. The control circuit (1) 'on the receiving side which has received the transmission mode data writes and stores the transmission mode data in a predetermined area of the data memory (5)'.

Therefore, when the control signal (a) is exchanged, the transmission and reception of the document data is started, but before that, the control circuit (1)
(1) 'reads the transmission mode data relating to the first original document stored in the data memories (5) and (5)', respectively, and sets the mode such as the sub-scanning speed based on the read data. When the setting of the transmission mode is completed, the control circuit (1) controls the reading unit (3) to read the first document data, and starts the transmission in the set transmission mode. On the other hand, the control circuit (1) 'on the receiving side, which has received the data transmitted from the transmitting side, controls the recording section (4)' according to the set mode to perform reception recording.

When the transmission of the first original data is completed in this way, a signal (EO
M signal) is transmitted, and a reception confirmation signal (MCF signal) is returned from the receiving side that receives this signal, transmission / reception of the first document is completed, and transmission of the second document is started. When transmitting and receiving the second original, the control circuits (1) and (1) 'read the transmission mode data relating to the second original from the data memories (5) and (5)' as described above, and set the mode. To do. After that, the transmission / reception is performed in the same manner as described above, and the transmission / reception is similarly performed for the third document. Then, at the end of all the original data, the control signal (b) is transmitted and received, the line is disconnected, and the transmission is completed. Thus, when sending multiple originals while changing the send mode,
It is not necessary to send and receive the control signal for each document, and the communication time can be shortened.

In the above description, it was necessary to input the transmission mode data for all originals. However, if the number of originals is large, it takes a considerable time to input the data. If you input the, and configure it to send and receive other originals in the preset standard mode, and change the mode when the number of stored originals is reached, you can input the transmission mode data. It will be easy.

(G) Effect of the Invention As described above, the facsimile system of the present invention inputs the transmission mode data for each page of a document consisting of a plurality of sheets before transmission, and transmits this data collectively when the first control signal is transmitted / received. By storing the data on the receiving side, even if transmission / reception of a control signal for changing the transmission mode is omitted during transmission, the transmission mode data stored in advance can be changed into a mode and a multi-page original can be stored. Since the data can be transmitted and received, the communication time can be shortened even when the transmission mode is changed on the way.
