The storage part is shown.
FIG. 2 shows the DTMF pattern character conversion table 11 described above.
An example of the contents of is shown. The DTMF pattern character conversion table 11 shown in this embodiment is constructed so as to correspond to a combination of two-digit numeral keys. The contents of the above-mentioned reserved word table 12, which is another table, are shown in FIG.
As illustrated in FIG. Hereinafter, the operation of data communication using the facsimile apparatus shown in this embodiment will be described in detail. First, the control information used in the facsimile apparatus according to this embodiment will be described. The control information referred to here is information used when the facsimile machine of the transmission destination is called from the outside and then the character information is controlled to be transmitted.

Here, the above-mentioned control information is defined as follows. "7": Set to the DTMF pattern acceptance mode. "* 1": Accept the following information as "numbers". "#": End of one division. "* 2": In the following information, up to "#" is accepted as hiragana or uppercase letters. "* 3": In the information that follows, up to "#" is accepted as Katakana or lowercase letters. "* 4": For the information after that, up to "#" is further converted as a predetermined reserved word. "* ##": DTMF pattern acceptance mode is terminated. Hereinafter, a specific operation will be described with reference to operation flow charts shown in FIGS. 4 and 5, taking as an example a case where a facsimile apparatus at home is contacted from outside. (1) Dial home from a public phone. Here, it is assumed that the home facsimile apparatus is set to the automatic reception mode.

(2) When the ring is detected (step 2

The facsimile machine side displays that it is in the "DTMF pattern acceptance mode" (step 23). (3) Hereafter, message data is input (steps 24-28). For example, when "* 2 # 326382812191 #" is input, this is converted into "from Shibuya (Shibuya)" by the conversion table 11 described above. Next, if you enter "* 4 # 03 #", this will result in the reserved word table 12

Even for a healthy person, the effect that the facsimile device can be used instead of the answering machine can be obtained. In the above description, an example is shown in which the sender operates the push-button telephone by himself to perform the transmission operation, but this is done efficiently by using a portable calculator-type autodialer. It goes without saying that it is also possible. As for the reception time, the reception time and the output time (when different from the reception time) in the facsimile machine may be automatically output. Furthermore, in the operation flow charts shown in FIGS. 4 and 5, if the facsimile device receives a response of "7" of the DTMF signal, a response is returned, which increases the sense of security of the sender (operator). effective. Next, another embodiment of the present invention will be described. In addition,
The present embodiment corresponds to the above-mentioned second invention.

FIG. 6 is a block diagram for explaining the configuration of a communication terminal device showing an embodiment of the present invention. In the figure, symbols 4, 6, 8 and 9 respectively indicate the same components as those of the previous embodiment shown in FIG.
Reference characters a, 2a, 3a, and 10a respectively represent components according to the components of the previous embodiment shown in FIG. The RAM 3a has a function of storing code information corresponding to character data input via the operation control unit.
Is a sampling data storage unit for storing sampling data corresponding to the character code, and 16 is a D / A converter. The operation of the communication terminal apparatus according to this embodiment configured as described above will be described below with reference to the operation flow chart shown in FIG. In addition, in the example shown below, the case of transmitting “Shibuya (Shibuya) will be returned” by key input will be taken as an example. First, the operator
For example, input is made from the operation unit by inputting Roman characters, and then dialing is performed to the transmission destination (step 41). The input data (character code) is stored in the RAM 3a as described above.

In the communication terminal device according to the present embodiment, the NSF
When / DIS is received, it is determined based on the received / DIS whether or not the facsimile machine of the other side has the function according to the present embodiment (steps 42 and 43). Needless to say, if the facsimile machine on the other end is not equipped with the function according to the present embodiment, the normal communication method is used (step 45). If the facsimile machine on the other end is equipped with the function according to the present embodiment, the NSS and DCS signals indicating the use of this function are transmitted (step 44).
Here, it is assumed that the performance of the device itself is set up with, for example, A4 size, transmission rate 9600 bpm, and encoding method MH method. After that, the TCF signal (continuous transmission of 0) is transmitted and the CFR signal reception process is performed (steps 46 and 47), and the preparation for transmission is completed. When the CFR signal is received, the communication terminal device according to the present embodiment retrieves the data of the input characters stored in the RAM 3a one by one as described above, and then responds to this from the sampling data storage unit 15 described above. The sampling data is taken out and sent to the facsimile machine on the other side (step 48).

The above-mentioned sampling data usually corresponds to a facsimile signal obtained by encoding the image data read by the scanner by the encoding / decoding device (DCR). Here, this corresponds to this. The feature is that it is obtained by sampling a character facsimile signal. When the sending of the sampling data corresponding to all the inputted character data is completed (step 49), the data end sampling signal is sent and then the EOP signal is sent (step 50). After that, when the MCF / RTN signal is received (step 51), the DCN signal is transmitted and the communication is ended (step 52). If necessary, the transmission contents are printed out from the own device (step 53). FIG. 8 shows an example of output according to the above embodiment. According to the above example,
Since the input characters can be converted into the corresponding sampling data and sent to the other communication terminal device, it is possible to realize a communication terminal device that can transmit image data without using a scanner. The effect is obtained.

Although not described in the above description, during operation based on this function, by setting up so that line errors are ignored, even if some line errors occur, the processing is interrupted. Without it, it is possible to create an image that is substantially harmless. It is needless to say that the above embodiments are examples of the present invention and the present invention should not be limited thereto.
