Abstract

PURPOSE:To print out a data unable to be recorded after power application among data received before power interruption by transferring the received data of a prescribed range including the received data not printed out in a volatile memory to a nonvolatile memory. 4 CONSTITUTION:A received data is inputted from a line input terminal 10, demodulated by a transmission/reception section 2, decoded by a decoding section 5, inputted to a recording section 6 and printed out on recording paper 7. When the recording paper 7 is short on the way of reception in this state, a sensor 8 detects it. When the page received at present is received to its end, a control section 7 terminates the communication. Thus, all the picture data of the page received at a point of time when the recording paper is in shortage is written in the volatile memory 3. On the end of communication, a control section reads the demodulated data by the page written finally from the volatile memory 3 and writes it into the nonvolatile memory 4. When new recording paper is set and the power is applied, the data in the nonvolatile memory 4 is read and decoded and printed out by a recording section 6.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Field of Industrial Application) The present invention has a function of temporarily storing received information and outputting the stored information that has not been recorded and output after replacing the recording paper. The present invention relates to a facsimile machine equipped with a facsimile machine.

(Prior Art) Conventionally, this type of facsimile apparatus includes a volatile memory such as a RAM and a non-volatile memory such as a hard disk, and received image data is simultaneously stored in both the volatile memory and the non-volatile memory. If the recording paper runs out during such a reception operation, the power is turned off when replacing the recording paper, so the contents stored in the volatile memory are lost, but the contents stored in the nonvolatile memory are retained. Therefore, after replacing the recording paper, the recorded contents of the non-volatile memory are read out, and the received data that could not be recorded and output due to the lack of recording paper is recorded and output on a newly set recording paper.

However, in the conventional configuration as described above, received data is stored in both volatile memory and non-volatile memory at the same time, resulting in a complicated data output/output circuit and a complicated data writing control program. there were. Therefore, it is conceivable that only non-volatile memory can be used5, but non-volatile memory is difficult to read/write in short cycles like RAM, so it is not practical from a performance standpoint to have only non-volatile memory. It wasn't.

(Problem to be Solved by the Invention) Conventionally, in this type of facsimile machine, received data is simultaneously stored in both volatile memory and nonvolatile memory, so the data writing circuit and data writing program are complicated. There was a drawback that the cost was correspondingly high. SUMMARY OF THE INVENTION Accordingly, the present invention aims to eliminate the above-mentioned drawbacks, and provides a facsimile device that records and outputs the portion of received data that was not recorded and outputted before the power is turned off using a simple circuit and program configuration after the power is turned on. Write the purpose.

[Structure of the Invention] (Means for Solving the 0! Problem) The present invention provides a facsimile machine that temporarily stores received data in a volatile memory and then sequentially reads the stored data and records and outputs it from a recording unit. a non-volatile memory for storing data; a detection means for detecting whether or not it is possible to record and output data from the recording section; and during reception, the detection means makes it impossible to output data from the recording section. a reception control means that receives received data up to a predetermined portion and stores the received data in the volatile memory, and then terminates the communication; A data transfer means for transferring a predetermined range of received data, including at least received data that has not been recorded and outputted, to the nonvolatile memory, and a notification that data can be output from the recording section by the detection means. Then, the recording control means reads out the received data transferred to the nonvolatile memory and causes the recording section to record and output the received data.

(Function) In the facsimile apparatus of the present invention, when the reception control means is notified by the detection means that output of data from the recording section is no longer possible, the reception control means receives the received data up to a predetermined portion and converts these received data. After storing in the volatile memory, communication is terminated and this is notified to the data transfer means.

When the communication is completed, the data transfer means transfers a predetermined range of received data in the volatile memory, including at least received data that has not been recorded or outputted, to the nonvolatile memory.

When the recording control means is informed by the detection means that data conversion is possible from the recording unit, the recording control means reads out the received data transferred to the nonvolatile memory,
This will be transferred from the recording section.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus of the present invention. 1 is a control unit that controls each part such as transmission/reception control and memory control, and controls the entire device; 2 is a transmission/reception unit that performs data transmission/reception processing; and 3 is a control unit that performs data reading/reception processing.
4 is a non-volatile memory in which data is read/written only when necessary; 5 is a decoding unit that decodes demodulated data; 6 is a recording unit that prints data on recording paper and outputs it. , 7 is a recording paper on which data is printed, 8 is a sensor that detects the presence or absence of the recording paper, 9 is a common bus through which control signals and data are transmitted, 10 is a line input terminal for connecting a telephone line, and 11 is a This is a display unit that displays dial information, device status, etc.

Next, the operation of this embodiment will be explained. At the time of reception, received data is input from the line input terminal 10, demodulated by the transmitting/receiving section 2, and passed to the demodulating/decoding section 5. Decoding section 5
decodes the passed data and sends it to the recording unit 6. The recording unit 6 prints the input data on a recording paper 7 and outputs it. Therefore, the data received by the transmitting/receiving section 2 is sequentially printed on the recording paper 7 and output. In such a state, if the recording paper 7 runs out during reception, the sensor 8 detects this and notifies the control section 1 of this. The control unit 1 is connected to the recording paper 8
When it learns that the page has run out, it displays a message indicating this on the display section 11 and controls the transmitter/receiver section 2 to end the communication when the page currently being received is received to the end.

Therefore, the volatile memory 3 contains at least all the image data of the pages that were being received at the time when the recording paper ran out. Therefore, when the control section 1 ends the communication, it reads demodulated data for the last page loaded and outputted from the volatile memory 3 and outputs it to the nonvolatile memory 4. When the operator sees the display indicating that recording paper B is out on the display unit 11, he turns off the power to the apparatus, replaces the recording paper B, sets a new recording paper, and then turns on the power to the apparatus. by this,
When the control unit 1 becomes operational again and receives a recording paper presence detection signal from the sensor 8, it reads out one page of demodulated data transferred to the nonvolatile memory 4 and decodes it. After decoding in the encoding unit 5, the recording unit 6 prints out the data. As a result, the operator can remove 1q of the received data that was not printed out in the middle of the page by checking the recording paper. Therefore, the sending side only has to start sending the document again from the next page.

According to this embodiment, when communication is temporarily interrupted, such as when the recording paper runs out during reception, after the communication is interrupted, the received data that has not been printed and outputted to the volatile memory 3 is The received data is written in the non-volatile memory 4, and then when the device is restored, the received data transferred to the non-volatile memory 4 is read out and printed out from the recording unit 6, so the received data is transferred to the volatile memory 3. It is not necessary to write to both of the nonvolatile memories 4 at the same time, simplifying the writing circuit and writing program, improving the reliability of the device, and reducing the cost of the device. Furthermore, the non-volatile memory 4 only needs to be able to store at least the received data that has not been printed out in the volatile memory 3, and a small capacity memory can be used to reduce costs accordingly. Note that if the volatile memory 3 has sufficient capacity, it is also possible to store a plurality of pages of received data and then interrupt the communication from the time when the recording paper runs out.

[Effects of the Invention] As described above, according to the facsimile apparatus of the present invention,
There is an effect that the part of the received data before the power is turned off that was not recorded and outputted can be used for recording after the power is turned on by using a simple circuit and program configuration.
