Abstract

(57) [Summary] [Purpose] To synthesize coded document data by voice, convert it to voice, and send the facsimile data as voice to terminals other than the facsimile. A CPU (Central Processing Unit) 1 that operates according to a program in a ROM 2 uses the data input from a keyboard 8 as document code data, and stores the RAM 3 or SR.
The data is stored in AM4 and communicates with the terminal having the telephone number input from the keyboard 8 through the NCU7. If the terminal on the other side is a facsimile, the document code data is converted into image data and transmitted according to the facsimile procedure. If the terminal is not a facsimile, the document code data is converted into voice by the voice synthesis processing circuit 6 and transmitted.

Regarding the conventional example configured as described above,
The operation will be described below. The data input from the keyboard 8 is processed by the CPU (Central Processing Unit) 1 and stored in the RAM 3 or SRA as code data of the document.
It is stored in M4.

According to the telephone number input from the keyboard 8, the NCU 7 connects to the other terminal.

The CPU (Central Processing Unit) 1 converts the document code data stored in the RAM 3 or SRAM 4 into bitmap image data and sends it to the other party according to the facsimile procedure.

As described above, the facsimile machine operates.

[0008]

However, the circuit configuration as in the above-mentioned conventional example has a problem that the receiving side cannot communicate with the communication device other than the facsimile device.

The present invention has been made in view of the above-mentioned problems of the conventional example, and an object thereof is to provide a communication device capable of transmitting a document even if the receiving side is a communication device other than a facsimile device. And

[0010]

To achieve the above object, the present invention provides a data communication device connected to a telephone line for transmitting and receiving image data and other data,
A CPU (central processing unit), which is mainly a microprocessor, is a ROM that stores a data processing program.
And a RAM and SRAM as a work area are connected via a bus, a keyboard for creating and inputting document data, a display device for displaying various data, a telephone number of the other party, image data and other data are sent and detected A modem, a voice synthesis processing circuit for synthesizing voice from a created document, and an NCU connected to an external telephone line are respectively connected to the bus, and the modem and the voice synthesis processing circuit are The communication device is characterized in that it is connected to the telephone line through the NCU, determines the data that can be received by the receiving terminal, and synthesizes the data and transmits the data to the terminal that cannot receive the image data.

That is, depending on the type of the voice synthesizing processing circuit for voice synthesizing the created document and the receiving device on the other side,
The communication device is configured by a switching unit that switches image data or sound.

[0012]

According to the present invention, with the circuit configuration described above, the document is transmitted as voice even if the receiving side is other than the facsimile machine.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a circuit configuration of a communication device according to an embodiment of the present invention.

In all the drawings, the same symbols represent the same or corresponding members. In FIG. 1, a CPU (Central Processing Unit) 1 is composed of a microprocessor and the like, and has a ROM 2 as a fixed storage means and a RAM as a work area.
A [dynamic RAM] 3 and an SRAM [static space RAM holds a memory for a time corresponding to a power failure] 4 are connected to control the operation of the entire device according to a program stored in the ROM 2.

The modem 5 detects transmission of telephone numbers, image data and the like and various signals, and the voice synthesis processing circuit 6 synthesizes voice from a document created by being coded. Then, the modem 5 and the voice synthesis processing circuit 6 use the NCU [netw
ork control unit] 7 is connected to the telephone line.

The keyboard 8 is an input device for creating a document and the like, and the display device 9 outputs various data.

The operation of the communication apparatus configured as described above will be described below with reference to the flowchart of FIG. FIG. 2 is a flowchart showing the operation of the communication device in the embodiment of the present invention.

The data input from the keyboard 8 is C
RA processed as PU1 code data
It is stored in M3 or SRAM4.

According to the telephone number [Step 21] input from the keyboard 8, the NCU 7 dials the terminal of the other party [Step 22], and when the terminal of the other party is connected, the CNG signal [colling tone signal] is transmitted. [Step 23].

The CPU 1 sends a CED signal [called station identificat] which is a signal for identifying the called terminal to the other terminal.
If the [ion signal] is transmitted [step 23] (Yes), it is confirmed to be a facsimile [step 24], and R
The document code data stored in the AM3 or SRAM4 is converted into bitmap image data [step 25] and transmitted to the other party according to the facsimile procedure [step 26].

The other terminal's terminal sends a called terminal identification signal (CE
If the D signal is not sent (No) [Step 24], it is confirmed that it is a telephone or an answering machine, and RA
The document code data stored in the M3 or SRAM 4 is converted into voice by the voice synthesis processing circuit 6 [step 27] and transmitted to the other party [step 28].

As described above, according to the present invention, coded document data can be switched between image data and voice depending on the type of terminal device on the other side and transmitted.

[0024]

As described above, according to the present invention, even if the other party's terminal is a communication device other than a facsimile, it can be transmitted by converting coded document data into voice, and its practical effect. Has a great deal. That is, according to the present invention, the document data (image data) on the transmission side
When the communication device on the receiving side cannot process the document data, it has a special effect that it can be communicated by synthesizing it into basic voice data to communicate with all the other parties.
