[Industrial application field]

The present invention relates to a video facsimile device that combines a video control function with a facsimile device and transmits and receives the contents of a videotape.

[Conventional technology]

An example of a conventional facsimile machine is shown in FIG.
Under the control of the main control section 10, a panel control section 11-2 provided with an operation panel section 11-1 performs various function settings and dials the desired transmission destination using a numeric keypad, one-touch key, etc. - Dial connection is established. , the original is sent to the reading section 16-
1, optically read by line scanning, sent to the data processing section 15-1 and data conversion section 15-2 via the reading control section 15-2, and compressed using, for example, the MH (Modified Huffman) method. , - are stored in the data storage section 15-5. On the other hand, if the transmission destination has an automatic reception function, a pre-procedure check is performed with the line control section 16-3, and a function setting is performed on the modulation/demodulation section 16-2. Here, data storage section 15-
The transmission control unit 16- restores and compresses the image information stored in the
1, through the modem section 16-2 and the line control section 16-6.
The carrier wave is then modulated with image information and sent out onto the line. Note that the automatic calling section 16-4 has an automatic dialing function using a one-touch key or the like.

Conversely, when the line control section 16-3 receives a carrier wave modulated with image information from the line, it is demodulated by the modulation/demodulation section 16-2.
Under the control of the transmission control section, the data is first passed through the data processing section 15-1 and stored in the data storage section 15-5. Alternatively, the data is restored by the data conversion section 15-2 and printed out on recording paper by the recording section 14-1 via the recording control section 14-2. In addition,
A mechanism section 12-1 related to reading, recording, etc. is controlled by a mechanism control section 12-2 according to the processing program.

As mentioned above, input and output in conventional facsimile machines was carried out using original documents or recording paper, and there was no method of directly inputting the contents of a video tape or the like and displaying it on a television.

On the other hand, as is well known, the commonly used method is to record video tapes with a video camera, insert them into a video deck, and display the audio on a television screen.

[The problem that the invention attempts to solve]

Conventional facsimile machines have input and output connections as described above, which causes the following problems. That is, on the receiving side, unless all image information is checked, it is impossible to judge whether it is necessary or unnecessary, and information cannot be viewed without checking during transmission and reception. Furthermore, it is not possible to easily file a large amount of sent and received information.

Furthermore, in order to transmit video information taken at home or the like to a remote television, the present inventor considered combining the function of a conventional video deck for displaying video tapes on a television with a facsimile machine.

SUMMARY OF THE INVENTION An object of the present invention is to provide a video facsimile device whose video tape reading, sending and receiving functions are adapted to facsimile functions.

[Means for solving problems]

In order to achieve the above object, as shown in the principle explanatory diagram of FIG. 1, under the control of the main control section 100, a means 15 for reading image information at the time of transmission, a means 14 for recording received image information at the time of reception,
Compress image information according to sending and receiving.

A facsimile device 1 having a data conversion storage section 15 for restoration and a line control section 16 for controlling transmission and reception between device lines.
Under the control of a video control section 200 connected to the main control section 10, means 21 reads and transfers the contents of the video tape, and transmits the video image information received by the facsimile machine into an audio/video format.
Interface means 2 for connecting to a video display device
5.

[Operation] The content of the video tape is sampled at a predetermined frequency by the video reading unit 21, and sent to the data conversion storage unit 15 via the video control unit 20 and main control unit 10, which matches the frequency of converted data in the facsimile device. By doing so, it is possible to share the data conversion and storage function, and the data is sent to multiple lines from the line input/output unit 16, similar to facsimile. On the other hand, when a line-modulated carrier wave is transmitted to the line input/output unit 16, it is demodulated in the same way as a facsimile machine, restored in the data conversion storage unit 15, and transmitted via the main control unit 10 and video control unit 20. Then, it is sent from the AV interface section 26 to the television device and displayed. In this way, the contents of the videotape are transmitted using a facsimile machine.
