Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device, and in particular,
The present invention relates to a facsimile device that can record not only text information but also sound information.

Conventionally, facsimile devices have been widely known as devices for recording and reproducing figures and characters on paper, but it is also being considered to use these facsimile devices to record and reproduce sound information as well.

However, since the conventional method was to transmit electrical signals of images such as figures and characters (analog signals) and electrical signals of sounds (analog signals) sequentially in time, it was difficult to distinguish between the two in terms of time. An intermediate signal was required (Special Publication No. 49-25605).

In addition, since both image and sound signals are transmitted as analog signals, it is difficult to compress the transmitted data and the line cost increases, especially for signals with complex waveforms such as audio signals. In order to transmit this analog waveform as a facsimile signal, a large amount of data was required.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile device that can easily compress transmitted data and that can transmit, record, and reproduce sound information easily and inexpensively.

To achieve this object, the present invention provides means for inputting and digitally encoding sound information, means for converting the digitally encoded sound information into a bit image of a digital signal, and a means for converting the digital signal into a bit image on paper. a means for reading the bit image of the digital signal recorded on paper; a means for inputting the bit image of the digital signal and converting it into digitally encoded sound information; The apparatus is provided with means for decoding the sound information and reproducing the sound information.

As a result, in the present invention, data transmission within the facsimile device and between the other party's terminal is performed using digitally encoded signals, making it easy to compress the data.On the other hand, recording on paper is performed using bit images of the converted digital signals. Since the signal is recorded directly on paper, it can be clearly distinguished from the image signal.

An embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram of a facsimile terminal device according to the present invention, and FIG. 2 is a diagram showing recorded contents recorded on a sheet of paper by the facsimile terminal device according to the present invention. This will be explained with reference to the figures.

First, a case will be described in which a user records audio on paper via his/her own recording unit and then reproduces the audio via his/her own reading unit. Instructions are issued to the microcomputer 3 using a well-known method such as operating a telephone key to enable this operation, and the relay PB and its contacts are
pb is working. In this state, the voice generated by the operator (not shown) is converted into digital code on the path of microphone 1 - voice coder 2 - contact PB - facsimile decoder 4 - head 5 based on an algorithm stored in microcomputer 3. (for example, converted into a PARCOR system code), the signals are converted into bit images of digital signals, and sequentially recorded on the recording paper 6. The recording sheets 6 are sequentially fed by a well-known method in which a motor 7 is operated under the control of the microcomputer 3. The end of recording the audio is determined by the microcomputer 3, for example, when recording for one A4 sheet of recording paper 6 is completed, and the LED (light emitting diode) 8 is activated.
At the same time, motor 7 and relay PB
This is done using a well-known method such as restoring the . Next, the operator sets this recording paper 6 in the reading section, issues a reading instruction to the microcomputer 3 using a well-known method such as electronic recording, and turns on the relay.
Assume that PB and its contact pb operate. By the operation of the microcomputer 3, the bit image of the digital signal on the recording paper 6 (for example, the audio pattern 103 after the audio identification mark 101 in FIG. 2) is generated.
Based on the algorithm stored in the microcomputer 3, the bit image of the digital signal is converted into a digital code (e.g. PARCOR code) on the path of sensor 9 - facsimile recorder 10 - contact PB - voice decoder 11 - speaker 12.
The data is converted into audio, which is further decoded and reproduced into audio, which is sequentially output from the speaker 12.
The recording sheets 6 are sequentially fed by a well-known method in which a motor 7 is operated under the control of the microcomputer 3. The end of the reading is, for example,
The microcomputer 3 determines that reading for 1 A4 sheet has been completed, and the process is executed by a well-known method such as igniting the LED 8 and restoring the motor 7 and the relay PB. Subsequently, when the terminal devices connected via the line 18 communicate with each other, the terminal device A side outputs audio information, and the terminal device B (not shown) side outputs audio information as the audio pattern 103 on the recording paper 6.
This section describes the case of recording. Terminal device A and terminal device B have exactly the same configuration, so FIG. 1 will be used in common for explanation. It is assumed that in terminal device A, the operator is instructing microcomputer 3 by a well-known method such as operating a telephone key to send voice information to terminal device B, and that relay S and its contacts s are operating. Establishment of a communication link between terminal device A and terminal device B and mutual synchronization between terminal device A and terminal device B are performed by microcomputer 3, modulator 13, demodulator 14, hybrid transformer 15, and network control unit 1.
It is assumed that the process ends with the well-known operation of step 6. In this state, the voice generated by the operator (not shown) is transmitted to the microphone 1 - voice coder 2 - contact S - modulator 13 - hybrid transformer 15 - network control unit 16 - based on the algorithm stored in the microcomputer 3.
Line 18, (Terminal A) Line 18 - Network control unit 16 - Hybrid transformer 15 - Demodulator 14 - Contact S - Contact PB - Facsimile decoder 4 - Head 5 - Recording paper 6, (Terminal B) The audio is encoded (for example, converted to PARCOR code) through the
Modulated by the modulator 13 (terminal device A)
Thereafter, the signals are demodulated by the demodulator 14, converted into digital signal bit images by the facsimile decoder 4, and sequentially recorded on the recording paper 6. Note that the recording sheets 6 are sequentially fed by a well-known method such as by operating a motor 7 under the control of the microcomputer 3. (Terminal device B) To end the recording, the microcomputer 3 of the terminal device A determines that a time equal to the recording of 1 A41 page has elapsed, lights the LED 8, restores the relay S, and then closes the line 13. This is carried out by a well-known method such as cutting off the modulated signal that was being sent out. In the terminal device B, the microcomputer 3 detects the interruption of the modulation signal and stops the motor 7, for example, by a known method.

As described above, according to the present invention, since the sound information is transmitted as a digitally encoded signal, the transmission data can be easily compressed, and the sound information can be transmitted, recorded, and reproduced easily and inexpensively.
