規格に準拠した制御手順方式を採用している。2. Description of the Related Art Conventionally, in order to increase the transmission speed of a facsimile apparatus, the transmission speed of a modem has been increased, and the transmission speed of an image signal has been improved by improving the compression ratio of image information. . In this type of facsimile apparatus, in order to enable transmission and reception of signals between different models, a control procedure system conforming to the standard of CCITT Recommendation T30 is adopted prior to transmission of an image signal.

た後、受信機からの約1秒の受信準備確認信号CFRを
待って画信号の送信に移行するものである。The procedure will be described with reference to the sequence shown in FIG. 7. First, after a calling side and a called side are connected by a line, a calling station identification signal CNG is transmitted from the calling side to the called side. Then, from the called side to the calling side, the called terminal identification signal CE
After transmitting D for 2.6 to 4.0 seconds, an initial identification signal of about 2 seconds including a non-standard device signal NSF, a called terminal identification signal CSI, and a digital identification signal DIS is further transmitted. On the other hand, after detecting these signals, the calling side issues a reception command signal for about 2 seconds including the non-standard device setting signal NSS, the transmitting station identification signal TSI, and the digital command signal DCS, and then for about 1.5 seconds. After transmitting the training check signal TCF, the process waits for a reception preparation confirmation signal CFR of about 1 second from the receiver and shifts to transmission of an image signal.

ており、送受信の回数が増大するに従って、通信コスト
の面からも無視できない浪費時間となっている。Therefore, according to the CCITT recommendation, various control procedure signals are transmitted and received until the transmission of the image signal from the line connection is started. Since these signals are transmitted at a transmission rate of 300 dpi based on a low-speed modem, Approximately several tens of seconds are required before the image signal starts, and as described above, even if the transmission time of the image information is shortened by speeding up the modem or the like, the transmission and reception of the control procedure signal, which is only a preparation operation, takes an extremely long time. For example, in recent years, the time required to transmit one A4 standard document has been reduced to about 10 seconds. Therefore, when only one document is transmitted, the ratio of the procedure control time to the total required time Has reached 60% or more, and as the number of times of transmission / reception increases, waste time cannot be ignored from the viewpoint of communication cost.

ー186044)In order to solve such a drawback, a non-standard procedure shortening signal HUC is added to the control procedure signal CNG from the calling side using a non-signal section from the called side to the transmission of the CED signal after the line connection. And the called party sends the HU
When the C signal is identifiable, the time is reduced by transmitting the control procedure signals of TCF, TSI, and NSS as a high-speed modem signal from the calling side in response to the response signal (Japanese Patent Application Laid-Open No. H10-157572). No. 61-263359) or after connecting a line, a binary procedure signal is transmitted to the called side, and as soon as the binary procedure signal is received by the called side, the initial identification signal is transmitted at the speed used for transmitting the image signal. A technique has been proposed in which the control procedure is returned to thereby shorten the control procedure. (Japanese Unexamined Patent Publication No.

余儀なくされる。However, in each of the prior arts described above, an identification signal for shortening the control procedure is responded to the called side, and based on whether or not the identification signal has been identified by the called side. The facsimile uses a public line, which is susceptible to noise or the like. Despite the model being able to shift to the shortened procedure, there are many cases where transmission is performed by the normal control procedure, and in particular, in the former case, retransmission is inevitable.

Is established,
A technique has been proposed in which every time destination data is input, a transmission parameter corresponding to the destination data is read from the memory unit, and transmission with the other party facsimile is performed based on the transmission parameter.

Although such a configuration is not disclosed in practice, the above-mentioned disadvantage is solved because the shortening control procedure can be automatically selected based on the destination data regardless of the noise of the public line.

In general, facsimile machines are generally introduced into offices under lease contracts, and equipment is frequently replaced due to severe technological innovation, because such replacement is performed without notice to the other party. In addition, there is no way for the other party to change the contents of the memory storing the shortened control procedure. This is the same when there is a line change,
In particular, not only when the facsimile is moved in the office, but also when the local station number in Tokyo is changed in recent years, all the memories cannot be used, which is a serious problem.

It is preferable to insert and synthesize an FSK-modulated identification signal between CNG signals conforming to the T30 standard, so that it is not necessary to shorten the transmission time of the CNG signal itself, and it is also based on CCITT. Since the modulation scheme of the low-speed modem unit is FSK, the composite CNG signal can be transmitted from the low-speed modem unit in the same manner as a standard-compliant CNG signal.

つながる。Therefore, according to such technical means, in the case of a called terminal whose communication type is unknown for the first time, transmission is performed according to a communication procedure conforming to the G3 high-speed facsimile standard, and a response signal returned from the called side. By discriminating whether or not the model is a conforming model based on the data and recording it in the storage means, it is possible to automatically shift to the shortening procedure from the next communication, thereby saving the transmission speed.

If the data is abbreviated destination data, the abbreviated procedure is selected.
However, even after transitioning to the shortened procedure, since transmission is performed while always determining whether or not the machine is compliant, even if the called party is switched to a non-compliant machine due to a model change, etc., this is immediately determined. Since the contents of the memory in the storage means can be automatically rewritten or erased while shifting to a normal procedure, the latest model data can always be automatically stored in the storage means. As a result, it is possible to easily cope with a change of a local station number or the like as well as a change of a model or a movement of a facsimile in an office without a notice on the called side.
