When the above method is performed, the facsimile communication system in the mobile unit shown in FIG. 2 operates as follows.

In the method (3), when the predetermined key 1b-1 of the telephone 1b is pressed, the start signal S1 assigned to the predetermined key 1b-1 is input to the cellular modem 2a. Then, the cellular modem 2a is activated and the controller section 2b is notified of it. Upon receiving the notification, the controller section 2b causes the station line section 2d to generate a calling signal S2 and output it to the facsimile apparatus 3. The facsimile device 3 responds to the calling signal S2 by
This can be done by operating the hook switch or the start key in the above method (4). As a result, the facsimile machine 3
Becomes an off-hook state by forming a loop with the adapter 2 via the cable B.

This state is Phase A (call setup) of the CCITT recommended T.30 transmission control procedure. Continuously communicate between the facsimile device 3 and the G3 communication control unit 2b-1 according to the procedures of phase B (pre-message procedure), C (message procedure), D (post-message procedure) and E (call cancellation). Is done.

(Problems to be Solved by the Invention) However, the above-described facsimile communication method has the following problems.

Following the pressing of the predetermined key 1b-1 of the telephone 1b at the end of conversation shown in the method (3), it is necessary to operate the hook switch or the start key of the facsimile apparatus 3 of the method (4) twice. Therefore, there is a problem that the operability at the time of transmitting the document becomes complicated.

Moreover, when it is necessary to lay out the facsimile device 3 in a place out of reach such as a rear seat in a state where the telephone 1b is mounted on the periphery of the driver's seat of a car, for example, the predetermined number of the telephone 1b at the end of the conversation is set. When the hook switch or the start key of the facsimile device 3 is operated after pressing the key 1b-1, the predetermined key 1b-1 of the telephone 1b is pressed, and then the facsimile device 3 is moved to a certain position and the hook switch or start is operated. Since it is necessary to operate the key, there is a problem in that the operability at the time of transmitting the document is further complicated.

The present invention provides a facsimile communication method in a mobile body, which solves the problem that the operability is complicated as a problem that the above-described conventional art has, by only changing the protocol without changing the hardware configuration. is there.

(Means for Solving the Problems) In order to solve the above problems, the present invention uses a wireless telephone device in a mobile body having a predetermined key for transmitting a start signal to call a receiving side, and then the predetermined A facsimile device having an automatic response function and a polling transmission function, which has an automatic response function and a polling transmission function, is set off in advance based on the start signal by operating a key, and the contents of the transmission document are sent to the receiving side. In a facsimile communication method in a mobile device for transmitting, a mode is set to the automatic response function, and a mode is set to the polling transmission function using a predetermined default value, and then the predetermined key is operated to automatically operate the facsimile apparatus. It is designed to be off-hook.

(Operation) In the present invention, since the facsimile communication method in the mobile body is configured as described above, after setting the mode of the facsimile apparatus to the automatic response function and also to the polling transmission function using a predetermined default value. By operating a predetermined key of the wireless telephone device, the facsimile device is automatically put off hook. As a result, it becomes unnecessary to operate the facsimile device when transmitting the document, and the operability is improved.

 Therefore, the above problem can be solved.

(Embodiment) FIG. 1 is a diagram showing a communication sequence for explaining a facsimile communication method in a mobile body according to an embodiment of the present invention, from a phase A of a calling signal S2 to a phase C image data transmission. It represents a communication sequence. The abbreviations used in this figure are based on CCITT Recommendation T.30. It should be noted that this facsimile communication method in the mobile unit is carried out by using the communication system having the same configuration as in FIGS. 2 and 3 only by changing the protocol without changing the hardware configuration.

In order to make a call from the telephone 1b of the wireless telephone device 1 to a specific receiving side and have the facsimile device 3 transmit a document after conversation, the following methods (1) to (3) are sequentially carried out. .

(1) The transmission original is set on the facsimile device 3 and the automatic response mode for automatically connecting the line is set by calling from the other party. After that, the polling transmission mode is preset (step 10). Here, normally, the polling transmission mode is to transmit a transmission original document set in advance by the transmission side in response to a request from the reception side in which the ID numbers for identifying the other party match. The transmitting side informs the registered ID number to the receiving side in advance, and the same ID number is input and collated. However, in the present embodiment, when the polling transmission mode is set, the ID number on the receiving side is not set, and the predetermined default value (value that does not register the ID number) remains set.

(2) The telephone 1b of the wireless telephone device 1 makes a call to a specific person and calls the person to talk (step 11).

(3) After the conversation with the other party is completed, the predetermined key 1b-1 of the telephone 1b is pressed (step 12). Then, the start signal S1 assigned to the predetermined key 1b-1 is transmitted via the cable A to the wireless device.
It is sent to the 1a side. At this time, the cellular modem of adapter 2
2a reads the data from the upstream serial signal line of the cable A, interprets the data as the data of the key, and notifies the controller unit 2b of the interpretation result. Immediately thereafter, the cellular modem 2a outputs an off-hook signal to the upstream serial signal line in order to hold the automobile telephone line. Upon receiving the notification, the controller section 2b outputs a control signal to the central line section 2d. Based on this control signal, the central line 2d
The S2 is output to the facsimile device 3.

The facsimile apparatus 3 receives the calling signal S2 from the adapter 2 and also receives the calling signal S2 to operate the automatic answering function to enter the off-hook state. Furthermore, the response signal (2100Hz) and DIS (R; Receive) from the silent state for 2 seconds
The signal (Digital Identification Signal) is transmitted continuously. On the other hand, adapter 2
Waits for the input of the response signal and the DIS (R) signal after transmitting the DIS (S / R; Send / Receive) signal in advance. After receiving the response signal and the DIS (R) signal, the adapter 2 sends a DTC signal (digital transmission command) to the facsimile device 3. With the above, the negotiation is completed, and the adapter 2 recognizes that the facsimile apparatus 3 is in the transmission mode.

Then, a training TCF signal (Training Check) is sent from the facsimile device 3 to the adapter 2, and the receiving side receives the training TCF signal.
Via CFR (Confiration to Receive, reception preparation confirmation)
When the signal is sent, the pre-communication procedure is established, so the transmission original is read from the facsimile apparatus 3 side, and the sequence shifts to the transmission of the image data of the content.

When the image data is sent from the sending side facsimile apparatus 3 to the receiving side, the image data is compressed by a predetermined compression method.
In addition to the MH method (Modified Huffman code, one-dimensional coding method) and MR method (Modified Read code, two-dimensional coding method) recommended by CCITT,
Original mode MMR method (Modified Modified Read code)
Etc. Image data is transferred to the adapter 2 using these methods.
To the receiving side via.

After the image data transmission is completed, the facsimile device 3 receives the RTC (control return) signal and the EPO signal (End of Procedu
Re, end of procedure). Then, the receiving side transmits an MCF (Message Confirmation) signal (not shown). Further, when a DCN (Disconnect, line disconnection command) signal (not shown) is sent out from the transmitting side facsimile apparatus 3, the communication line is disconnected and the transmission of the original document ends.

The present embodiment is completely different from the generally used method of polling transmission of a facsimile machine, but since the facsimile machine 3 is automatically off-hook, one touch of the predetermined key 1b-1 is performed. The contents of the transmission original can be transmitted by operation.

Note that the present invention is not limited to the illustrated embodiment, and various modifications are possible. For example, there are the following modifications.

(A) In the above embodiment, the moving body is an automobile, but may be a moving body such as a train. Further, the present invention is applied not only to the case where the receiving side is called and the original document is transmitted by the facsimile device 3 after conversation, but also to the case where the receiving side is called and the original is transmitted without conversation.

(B) The predetermined key 1b-1 for transmitting the start signal S1 is the start signal S1.
A call-dedicated key may be used, or a key assigned with another function may be used to make a call.

(Effects of the Invention) As described in detail above, according to the present invention, if the polling ID number is set to a predetermined default value, the sending side can send to any other party. Then, the facsimile machine is set to the automatic response function and the polling transmission function is set to the predetermined default value, and then the predetermined key of the wireless telephone device is operated to automatically make the facsimile machine off-hook. Therefore, when transmitting the content of the transmission original, the operation of the facsimile device is not required at all, and the transmission can be performed by one-touch operation of a predetermined key in the wireless telephone device. As a result, it is possible to improve the operability at the time of transmitting an original by only changing the protocol without changing the hardware configuration.
