Abstract

PURPOSE:To receive picture information to be sent without fail even in a condition that the information can not be recorded during reception by always storing a update page in a storage part simultaneously with record processing during the reception. CONSTITUTION:In correspondence to the instruction of a control part 7, a switcher S1 is operated and the received information are passed through a line input part 1 and line control part 2 and demodulated in a demodulation part 3. While the information are stored to a storage part 6, the information are recorded through a decoding part 4 to a recording part 5. When the recording is normally finished, the information in the storage part 6 are erased. When the recording can not be executed, the contents of the storage part 6 are not erased but a signal from the demodulation part is successively stored in the storage part 6. Then, communication is finished. When it is detected that the possibility of the recording is recovered, the control part 7 makes a reproducing instruction signal 'H' and the switcher S1 is changed over. Then, the signal stored in the storage part 6 is read and recorded through the decoding part 4 io the recording part 5. After that, the number of originals requested from an opponent terminal is recorded without fail.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to facsimile devices.

[Conventional technology]

In conventional facsimile apparatuses, if a recordable state occurs during reception, communication is interrupted and subsequent image information cannot be received until the terminal becomes recordable. Therefore, when such a situation occurs, it takes time to receive all the requested number of sheets from the other party's terminal.

FIG. 2 is a block diagram of an example of a conventional facsimile device.

As shown in FIG. 2, the image information received via the line input section 1 and the line control section 2a is demodulated into a coded image signal by the demodulation section 3, and is decoded in a predetermined manner by the decoding section 4. The recorded signal is recorded by the recording section 5.

In this way, since the image signal is directly transferred to the decoding section 4, the control section 7 detects when the recording section 5 runs out of recording paper during recording. If this is detected, recording of the image signal cannot be continued after that, so reception is immediately interrupted, and the line control unit 28 notifies the transmitting side that reception is not possible, and the line is disconnected.

Therefore, it was not possible to receive all the requested number of sheets from the other terminal until the unreceivable state was recovered.

[Problem to be solved by the invention]

The above-mentioned conventional facsimile machines are designed to interrupt reception if it becomes unrecordable during reception, so it may not be possible to receive all the number of sheets requested by the other party's terminal, and if the terminal is in a recordable state. The disadvantage is that the remaining information cannot be received until the

[Means to solve the problem]

The facsimile apparatus of the present invention includes a line input section for connecting a telephone line, a line control section for receiving image information, a demodulation section for demodulating the image information and outputting an image signal, and a demodulating section for demodulating the image information and outputting the image signal in units of pages. a storage section for storing, a switch for switching outputs of the storage section and the demodulation section according to a reproduction instruction signal, a decoding section for decoding the image signal, and a recording section for recording the decoupled signal. , and a control section that outputs the reproduction instruction signal when detecting recovery from the unreceivable state.

〔Example〕 Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

As shown in Figure 1, a line input section 1 for connecting a telephone line
and a line control unit 2 that receives image information obtained by modulating a predetermined encoded image signal at a rate corresponding to the line transmission speed;
A demodulation section 3 demodulates image information and returns it to an image signal, a storage section 6 that stores the image signal in page units, and a storage section 6 that decodes the image signal using a decoding method corresponding to the encoding method and outputs a recorded image signal. A decoding unit 4, a recording unit 5 that records a recorded image signal, and a recording unit 5.
a control unit 7 which outputs a reproduction instruction signal when it detects that the image signal has recovered from the unrecordable state, and instructs to clear the recorded image signals page by page; It includes a switch S1 that switches between the output and the output of the storage section 6.

In this embodiment, the latest page is always stored in the storage unit 6 at the same time as the recording process is performed during reception between facsimile machines. When that page is recorded normally, the storage section 6 is cleared and the above process is continued again.

Now, if there is no recording paper during reception, the image signals being stored in the storage section 6 will not be cleared and will continue to be stored in the storage section 6 thereafter. Thereafter, when the unrecordable state is recovered, the storage unit 6
The image signal is leaked and recorded.

In this way, by temporarily accumulating image signals, it is possible to reliably receive the number of images requested by the other party's terminal without omitting any images.

Next, the operation of the embodiment shown in FIG. 1 will be explained.

In the recordable state (during normal operation), the switch S1 supplies the image signal from the demodulator 3 to the decoding unit 4 in response to a low-level reproduction instruction signal from the control unit 7. The image information received via the line control section 2 is demodulated by the demodulation section 3, stored in the storage section 6, decoded via the decoding section 4, and recorded by the marking section 5. When the recording is completed normally, the image information in the storage section 6 is erased.

Now, when the recording section 5 is in a state where it cannot record, the image signals sent from the demodulation section 3 are stored in the storage section 6 one after another without erasing the contents of the storage section 6, and then the communication is carried out. Terminate it.

When detecting that the recording unit 5 has recovered to a recordable state, the control unit 7 sets the reproduction instruction signal to a high level and switches the switch S1.
receives a high-level reproduction instruction signal and switches to supply the output of the storage section 6 to the decoding section 4, and the image signals stored in the storage section 6 are successively output and decoded by the decoding section 4. , by recording in the recording unit 5, the number of sheets requested by the other party's terminal is reduced to 1.
It is possible to record without missing a page.

〔Effect of the invention〕

As explained above, the present invention constantly stores the latest page in the storage unit at the same time as the recording process during reception.
Even if it becomes impossible to record during reception, it is possible to reliably receive the image information that is subsequently sent, which has the effect of improving line usage efficiency.
