Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] An object of the present invention is to provide a facsimile device that can store and transmit voice information as well as image information while suppressing cost increases.

[Prior art]

As a conventional facsimile device, for example,
There is one shown in the figure. This facsimile device includes a reading section 1 that scans an original image for transmission using a CCD or the like and extracts changes in shading as electrical signals, an image signal processing section 2 that amplifies the image signal from the reading section 1 and performs necessary corrections, and an image signal processing section 2 that amplifies the image signal from the reading section 1 and performs necessary corrections. a buffer memory 3 that temporarily stores the image signal from the signal processing unit 2; a modulator (MOD) 4 that encodes the image signal read out from the buffer memory 3 and then modulates it in a predetermined mode;
A line network control unit (NCU) 5 that sends the modulated image signal to the line or transmits the signal from the line to the receiving unit, and demodulates the modulated image signal received from the other party via the NCU 5. A demodulator (DEM) 6 and a buffer memory 7 that temporarily stores the image signal from the demodulator 6 after decoding it.
, a recording conversion unit 8 that converts the image signal from the buffer memory 7 into energy in the form necessary for recording (for example, voltage in the discharge destruction method), and a recording conversion unit 8 that converts the image signal from the buffer memory 7 into energy in the form necessary for recording (for example, voltage in the discharge breakdown method), and converts the energy obtained by the conversion unit 8 into reading and scanning on the transmitting side. and a recording scanning section 9 that applies the image to the recording paper at the same speed.

In the above configuration, when transmitting an image to a specific party via a telephone line, etc., the image is read by an image sensor such as a CCD while conveying the document at a constant speed, and signal processing is performed by the image signal processing section 2. After that, it is stored in the buffer memory 3. Next, the data is read from the memory, subjected to FM modulation, etc. using MOD4, and then sent to the line via NCU 5, and transmitted to the other party's facsimile machine via the line.

During reception, the image signal from the other party is received by the NCU 5 via a line, demodulated by the DEM 6, and then temporarily stored in the buffer memory 7, and the recording converter 8 generates a voltage to be applied to the sliver head. Furthermore, the voltage generated by the recording conversion section 8 is applied to the stylus head by the recording scanning section 9 at the same speed as the reading scanning on the transmitting side (in the above transmission/reception operation, the image signal is encoded,
(Description of decoding is omitted). As described above, images can be transmitted and received in a short time using a transmission line.

However, with conventional facsimile machines,
Since it only targets the transmission of image information,
It was not possible to send and receive voice information via the facsimile transmission system.

In addition, as a method for transmitting and receiving voice information via a facsimile transmission system, for example,
As described in Publication No. 50665, the voice data obtained by analyzing the voice signal from the microphone with a voice analyzer is sent to the transmission system via the buffer memory, and the received signal is sent to the voice synthesizer via the buffer memory. A method has been proposed in which the audio signal is obtained by transmitting the audio signal. However, since this method requires a large amount of audio data, a high-speed IC memory must be used as the buffer memory, making it expensive.

In addition, as shown in Japanese Patent Application Laid-Open No. 55-15135, a code reading device converts an audio signal into a stored image, sends it as an image signal to a normal facsimile transmission system, and converts the received image data into an image. Methods for converting audio data into audio signals have also been proposed in An operation is required to send this image signal by facsimile, and the receiving side also requires a means to convert the image signal into an audio signal, and an operation to record the received image signal on a hard copy. This requires an operation to convert the image signal into an audio signal, which not only makes the device expensive but also complicates the operation.

[Object and structure of the invention]

The present invention has been made in view of the above-mentioned problems, and in order to be able to handle audio information in a facsimile transmission system in the same way as image information while suppressing cost increases, it uses audio data obtained by analyzing audio signals to be transmitted. The received audio data is stored in the secondary memory for transmission via the primary memory for transmission, and the received audio data is stored in the secondary memory for reception via the primary memory for reception.Speech synthesis is performed through the primary memory for reception. The present invention provides a facsimile device that performs the following operations.

〔Example〕

Hereinafter, a facsimile apparatus according to the present invention will be explained in detail.

FIG. 2 shows an embodiment of the present invention, and the same parts as in FIG. A voice analyzer 11 generates voice data by analyzing the voice signal waveform picked up by the voice signal waveform and extracting features, and a buffer memory 3 (high-speed
a secondary storage memory (a floppy disk or hard disk is used to reduce cost increase) 12 which stores data via an IC memory (IC memory) and transfers it to a buffer memory 3 as necessary;
Through buffer memory 7 that uses IC memory
A secondary storage device 13 such as a floppy disk or hard disk stores the voice data of the other party from the DEM 6 and transfers it to the buffer memory 7 as necessary, and a secondary storage device 13 such as a floppy disk or hard disk stores the voice data of the other party from the buffer memory 7 and recognizes and synthesizes the voice data of the other party from the buffer memory 7 to generate an audio signal. Voice synthesizer 14 to obtain and voice synthesizer 14
An amplifier 15 for amplifying the audio output signal and a speaker 16 driven by the amplifier 15 are added. Although not shown, image information and audio information are not used at the same time, and only one of them is handled by switching.

In the above configuration, the transmission of image information is as described above, so the explanation will be omitted.
Voices such as messages from the microphone are analyzed by a voice analyzer 11, converted into voice data, and then sent to a buffer memory 3. The audio data stored in the buffer memory 3 is sent to the MOD 4, or is stored in the secondary storage device 12, read out at a desired time, and sent to the MOD 4 via the buffer memory 3. The modulated audio data is sent from the MOD 4 to the line via the NNU 5. On the other hand, voice data from the other party is received by the NCU 5, demodulated by the DEM 6, and stored in the buffer memory 7. The data is immediately sent from the buffer memory 7 to the voice synthesizer 14, or it is stored in the secondary storage device 13, and then sent from the secondary storage device 13 to the voice synthesizer 14 via the buffer memory 7 at the desired playback time.
Send data to. The voice synthesizer 14 that receives the voice data synthesizes voice based on the data and restores normal voice. voice synthesizer 1
Since the voltage level of the audio signal output from 4 is small, it is amplified to a predetermined level by amplifier 15,
Drive the speaker 16.
