Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention has a function of temporarily storing received information and outputting stored information that has not been recorded and output after exchanging recording paper. The present invention relates to a facsimile machine provided.

(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 receiving operation, the power is turned off when the recording paper is replaced, so that the storage content of the volatile memory is lost, but the storage content of the nonvolatile memory is retained. For this reason, after the recording paper is exchanged, the recorded contents of the non-volatile memory are read, and the received data, which could not be recorded and outputted due to the absence of the recording paper, is recorded and outputted on a newly set recording paper. However, in the conventional configuration as described above, since the received data is simultaneously stored in both the volatile memory and the nonvolatile memory, the data writing circuit becomes complicated and the data writing control program becomes complicated. . Therefore, it is conceivable to provide only a nonvolatile memory, but it is difficult to perform read / write in a short cycle like a RAM, and it is not practical in terms of performance to provide only a nonvolatile memory. Was.

(Problems to be Solved by the Invention) Conventionally, in this type of facsimile apparatus, since the received data is simultaneously stored in both the volatile memory and the nonvolatile memory, the data writing circuit and the data writing program become complicated. There was a disadvantage that the cost was increased accordingly. Therefore, the present invention eliminates the above disadvantages,
It is an object of the present invention to provide a facsimile apparatus that records and outputs after reception of power by using a simple circuit and a program configuration a portion of the reception data that is not recorded and output before the power is turned off.

[Means for Solving the Problems] The present invention relates to a facsimile apparatus for temporarily storing received data in a volatile memory, sequentially reading the stored data, and recording and outputting the data from a recording unit. A non-volatile memory for storing, a detecting unit for detecting whether or not data can be recorded and output from the recording unit;
When it is notified that the output of the data from the recording unit is disabled by the detecting means, the received data is received at least until the end of the page being received, and the received data is stored in the volatile memory. Receiving control means for ending communication, data transfer means for transferring received data of a page including received data not recorded and output in the volatile memory to the nonvolatile memory when the communication is completed, and the detecting means A recording control unit for reading out the received data transferred to the nonvolatile memory when notified that data can be output from the recording unit and recording and outputting the data from the recording unit. Have.

(Operation) In the facsimile apparatus of the present invention, when the reception control unit is notified by the detection unit that data output from the recording unit has become impossible, the reception control unit receives the received data at least to the end of the page being received. After storing the received data in the volatile memory, the communication is terminated, and this is notified to the data transfer means. When the communication is completed, the data transfer means transfers the received data of the page including the received data not recorded and output in the volatile memory to the nonvolatile memory.
When the recording control unit is notified by the detection unit that data can be output from the recording unit, the recording control unit reads the received data transferred to the nonvolatile memory and causes the recording unit to output the data.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of the facsimile apparatus of the present invention. 1 is a control unit that controls each unit such as transmission / reception control and memory control, and controls the entire apparatus. 2 is a transmission / reception unit that performs data transmission / reception processing. 3 is a volatile memory from / to which data is read / written. Non-volatile memory from / to which data is read / written only when necessary, 5: a decoding unit for decoding demodulated data, 6: a recording unit for printing and printing data on recording paper, 7: a record for printing data Paper, 8 is a sensor for detecting the presence or absence of recording paper, 9 is a common bus for transmitting control signals and data, 10 is a line input terminal for connecting a telephone line, and 11 is dial information and device status. It is a display unit to perform.

Next, the operation of this embodiment will be described. At the time of reception, received data is input from the line input terminal 10, demodulated by the transmission / reception unit 2, and passed to the decoding unit 5. Decoding section 5
Decrypts the passed data and sends it to the recording unit 6. The recording unit 6 prints and outputs the data recording paper 7 that is input. Therefore, the data received by the transmission / reception unit 2 is sequentially printed on the recording paper 7 and output. In such a state, when the recording paper 7 runs out during the reception, the sensor 8 detects this and notifies the control unit 1. The control unit 1 includes a recording paper 8
When it is determined that the page has disappeared, a message indicating this is displayed on the display unit 11 and the transmission / reception unit 2 is controlled to terminate the communication when the current page is completely received. Therefore, at least the image data of the page received at the time when the recording paper runs out is completely written in the volatile memory 3. Therefore, when the communication is completed, the control unit 1 reads out the demodulated data for the last page written from the volatile memory 3 and writes the demodulated data to the nonvolatile memory 4. When the operator sees the display indicating that there is no recording paper on the display unit 11, the operator turns off the power of the apparatus and replaces the recording paper, and turns on the power of the apparatus when a new recording paper is set. As a result, when the control unit 1 becomes operable again and receives the detection signal of the presence of the recording paper from the sensor 8, it reads out the one-page demodulated data transferred to the nonvolatile memory 4 and decodes it. After the decryption by the converting unit 5, the recording unit 6 prints out. As a result, the operator can obtain the received data that is not printed out in the middle of the page due to the absence of the recording paper. Therefore, the transmitting side only has to start transmitting the original again from the next page.

According to the present embodiment, when the communication is temporarily interrupted such as when the recording paper runs out during reception or the like, the communication is interrupted, and then the non-printed received data written in the volatile memory 3 is stored in the nonvolatile memory 3. Write it to memory 4 and then
When the device is restored, the received data transferred to the nonvolatile memory 4 is read out and printed out by the recording unit 6, so that it is necessary to write the received data to both the volatile memory 3 and the nonvolatile memory 4 simultaneously. In addition, the writing circuit and the writing program can be simplified, the reliability of the device can be improved, and the cost of the device can be reduced. In addition, the nonvolatile memory 4 only needs to be able to store the received data of the volatile memory 3 that is not printed out at a minimum, and the cost can be reduced by using a small capacity memory. If there is enough space in the volatile memory 3, the communication may be interrupted after storing the received data of a plurality of pages from the point when the recording paper runs out.

[Effects of the Invention] As described above, according to the facsimile apparatus of the present invention, it is possible to record and output the received data before power-off that has not been recorded and output after power-on with a simple circuit and program configuration. There is. Further, since recording and output are performed in page units, it is possible to easily determine where transmission should be started again.
