Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a facsimile apparatus having a storage means for storing image signals and capable of memory reception for storing received image signals in the storage means.

[Technical Background of the Invention] Conventionally, facsimile devices capable of memory reception are known. In this type of facsimile machine, the above two functions were considered to be independent, as is clear from the fact that the function of simultaneously recording and outputting was not activated during memory reception, and conversely, the memory receiving function was not activated during recording and output.

[Problems in the Background Art] For this reason, in the above-mentioned conventional facsimile apparatus, if there is a recording output failure such as a paper shortage or paper jam during recording output, the image signal cannot be preserved at all, and the image signal is requested to be retransmitted. I had no choice but to do it. For this reason,
Not only is the re-communication operation troublesome, but also when a recording output failure occurs during recording output, the same image signal is sent, resulting in wasted communications. Furthermore, since the memory receiving function and the recording output function were considered to be independent, no countermeasures against recording output failure when these two functions operate simultaneously have been considered. In other words, the memory reception function includes broadcast communication, etc., and when an evacuation function in the event of a recording output failure is added to this, when recovering from a recording output failure, it is possible to clearly distinguish image signals from other purposes. It has not been possible to accurately read out the image signals related to the above-mentioned shunting.

[Object of the Invention] The present invention was made in view of the drawbacks of conventional facsimile devices, and its purpose is to provide a system that can accurately deal with recording output failures during recording output, and eliminates the need for troublesome operations such as retransmission. , a facsimile device that can eliminate communication waste, easily and accurately identify image signals that have been saved in the event of a recording failure, and that can be read out clearly distinguishing them from image signals stored for other purposes. The goal is to provide the following.

[Summary of the Invention] Therefore, in the present invention, a facsimile device has a storage means for storing image signals, and a facsimile device stores received image signals in the storage means, and performs recording output based on the received image signals. In some cases, a recording output failure detection means detects a recording output failure, and when the recording output failure detection means detects a recording output failure, the image signal received thereafter is stored in the storage means for saving. a file containing information regarding the storage area of the image signal in the storage means with respect to the image signal stored in the storage means by the storage means;
A management table is created and stored in which information on this file number and a code indicating that the image signal is an image signal to be saved in the event of a recording output failure are stored in association with each other to prevent the recording output failure from occurring. The above object is achieved by providing a preparation processing means for preparing for recording output after restoration of the system.

A sensor (not shown) is connected to the paper shortage/paper jam detection circuit 82, and based on a signal from this sensor, the paper shortage/paper jam detection circuit 82 sends paper shortage/paper jam detection data to the CPU 20. Send. As data other than the above, the CPU 20 is given, from the incoming communication detection circuit 7, incoming data based on the detection of a paging signal and data indicating that communication is in progress based on the detection of the formation of a DC loop with the line.

The facsimile device configured in this manner is capable of performing broadcast communication, mailbox communication, relay broadcast communication, proxy reception communication, and multi-copy communication in addition to normal communication with the other party's facsimile device.
Here, broadcast communication refers to sequentially transmitting the same image signal to multiple destinations. Mailbox communication is a mailbox communication in which a box is provided to store the received image signal, and upon receiving a storage request from the other party's facsimile device to a box with a desired number, the received image signal is stored in that box. This communication is designed to perform recording and output based on the received image signal when a predetermined operation input is received. Substitute reception communication means that if a problem occurs due to a paper shortage while communicating with recording output immediately after receiving an image signal, the image signal after the problem occurs will be stored in memory, or the above-mentioned If a problem occurs in the recording output based on the image signal stored in the memory, the image signal stored in this memory can be used again, and the recording output based on the image signal in the memory is performed after the problem is resolved. It is a communication that enables Relay broadcast communication refers to sequential broadcast communication of received image signals to destinations requested by a sender. In this relay broadcast, the own station may be designated as the broadcast destination. Multi-copy communication refers to communication that allows the number of copies to be recorded and output based on a received image signal to be the number of copies requested by the source of the received image signal.

During the above communication, for communications other than broadcast communication (sending) and proxy reception communication, from the other party's facsimile device,
Information indicating which type of communication it is and necessary information are provided as follows.

One method is to include information in the NSS signal sent from the other party's facsimile device (transmitter T), as shown in FIG. 2A. At this time, the necessary information is destination data for relay broadcast communication, box number data for mailbox communication, and number of sheets data for multi-copy communication. Furthermore, although source data is sent in any communication, this transmission data may be unnecessary as appropriate.

Another method is to have the other party's facsimile device send out the above information using a DTMF signal, as shown in FIG. 2B. In other words, the first
Since the facsimile device in the figure is receiver R, the CED signal, NSF, CSI, and DIS signals are sent from receiver R, and the operator of transmitter T listens to these signals.
The desired DTMF signal is transmitted by operating the telephone's dial keys.
For example, "#" and "1" are mailboxes, "*"
Decide that "1" is for relay broadcast, "#" and "2" are for multi-copy, and from the next third digit, the necessary information can be accessed using the numeric keys, and the end is indicated by "*". . This DTMF signal is sent to DTMF via NCU4.
The signal is received by the signal receiving circuit 81, and decoded data based on the DTMF signal is provided to the CPU 20.
When the CPU 20 accepts this, it sends back an ACK via the NCU 4, and when it does not accept it, it sends a NACK.
to be sent back. Here, ACK is, for example, a continuous tone at a predetermined frequency, and NACK is an intermittent tone at a predetermined frequency. Hearing this tone, the operator can confirm whether the data has been accepted. Next, NSF, CSI, and DIS signals are sent from receiver R, and when the transmitter T side switches from a telephone to a facsimile device and operates the transmit key,
NSS and DCS signals are sent from the transmitter T, and the transmission and reception of signals continues in the same transmission control procedure as in FIG. 2A.

Next, FIG. 3 shows the relationship between the management table and files used by the CPU 20 to manage data in the RAM 13 or the disk 62. Here, the management table 101 is located in the RAM 21, and the file 102 is located in the RAM 13 or the disk 62. The management table 101 is divided into code data 103 indicating broadcast communication, code data 104 indicating multi-copy communication, code data 105 indicating proxy reception communication, and code data 106 indicating mailbox communication. Flag column 10 indicating whether or not processing is required corresponding to each code data
7 is provided, and a file number data column 108 (in the case of mailbox communication, box number data is also stored) is provided so that file number data of the file to be processed can be stored.
RAM13 using file No. data as address
Alternatively, by accessing the disk 62, the corresponding file can be read. The head (first area) of the file 102 contains the number of pages (number of originals), time to send, time to receive, sender ID (dial number), number of pages to be recorded and output, trouble pages,
Destination data and the like are stored, followed by image signals. Therefore, when input for broadcasting, relay broadcasting, multi-copy, substitute reception, and mailbox communication are performed, the CPU 20 sets the corresponding flag in the flag column 107 and also saves the image signal etc. to an empty file. Store the file number data of this file in the corresponding file number data column 10.
Write to 8. In addition, CPU20 is flag column 1
07 at a predetermined cycle, and when the flag is set, the corresponding file number data is read out, and the file 102 is accessed based on this. Then, the CPU 20 immediately starts recording output for multi-copy communication, and starts communication for broadcast (including relay broadcast) communication at that time if there is a time designation, or immediately if no time is designated. Regarding proxy reception communication and mailbox communication, if a predetermined operation is performed, recording output is started. In addition, the management table 10 of RAM21
Areas other than 1 are used as registers and flags.

Next, the specific operation of the CPU 20 will be explained with reference to the flowcharts of FIGS. 4 to 6.
The programs of the flowcharts shown in FIGS. 4 to 6 are stored in the ROM 22.

(Reception Operation) The flowchart in FIG. 4 is a flowchart at the time of reception. As described in the explanation of FIG. 2, the CPU 20 obtains information indicating which type of communication and necessary information from the other party's facsimile device using the NSS signal or the DTMF signal.

Therefore, the CPU 20 refers to the information indicating which of the above communications is being used and checks whether the communication is relay broadcast communication, mailbox communication, or multi-copy communication (201, 202, 203). If it is a relay broadcast communication, a flag in the management table 101 corresponding to the code data of the relay broadcast communication is set, and the file number data in which the image signal is to be stored is written (204).
Next, the CPU 20 sends the destination data and sender ID to the file 102 corresponding to the above file No. data.
etc., and transfers the image signal using DMA1.
4 to do it 205. If transmission time data is input, the CPU 20 also stores that data in the file 102. That is, except for receiving image signals, the CPU 20 transmits and receives control signals from the modem control unit 5 and NCU 4 via the buses 40, 50, and 70, and stores necessary information in the file 102 (when necessary, the DTMF signal receiving circuit 81, bus 90
route. ) When receiving the image signal,
The CPU 20 starts the decoding unit 10 and the DMA 14, passes the necessary data to the DNA 14, and the bus 40,
The occupation of 50 and 70 is transferred to DMA14. Thereby, the DMA 14 stores the image signal decoded and extended by the decoding unit 10 into the file 102.

Further, the CPU 20 checks 206 whether or not the own station is included in the destination data in the information obtained by any of the methods described in the explanation of FIG. When the destination data includes the own station, the CPU 20 performs control 207 so that recording and output are performed based on the image signal of the file 102. In this case,
The CPU 20 transfers control to the DMA 14, and the DMA 14
This allows the image signal to be transferred between the RAM 13 or the disk 62 and the recording section 8. The recording unit 8 performs recording output based on the image signal. During this time
The CPU 20 checks 208 whether there is a paper shortage or paper jam based on the detection data sent from the paper shortage/paper jam detection circuit 82 . If there is a paper shortage or paper jam,
The CPU 20 sets a flag corresponding to the code data of the proxy reception communication in the management table 101, and also sets the file number data of the file 102 in which the image signal related to the recording output is stored in the corresponding file number data column 108. Register to 209. In this manner, the CPU 20 performs recording output preparation processing for the image signals stored in the file 102 for relay broadcasting in preparation for recording output after the recording output failure is resolved.

On the other hand, during mailbox communication, the CPU
Step 20 sets a flag in the management table 101 corresponding to the code data of the mail box communication, and writes the received box number data (file number data) into the file number data field 108 (step 210). Next, the CPU 20 stores information such as the source ID and destination name in the file 102 corresponding to the file No. data, and transfers the image signal to the DMA 1.
4 to do 211. Next, the CPU 20 reads the necessary information from the head of the file 102,
Box management data is created and sent to the pattern generation circuit 12, a character pattern (image signal) is generated, and this character pattern (image signal) is sent to the recording section 8 (212). The recording section 8 performs recording output based on this character pattern (image signal). FIG. 7 shows a record table 501 that has been recorded and output. In this record table 501, from the right side, sender data, mailbox number, destination, total number of pages, and reception time are printed. This record sheet 501 is distributed to the recipient.

In communication between the relay broadcast and the mailbox, the CPU 20 checks 213 whether or not the information sent from the other party's facsimile machine includes data indicating a request for a reception list. When there is data indicating a request in the reception table, at the end of the reception operation,
The CPU 20 sends out a control signal indicating that an image signal is to be transmitted via the modem control unit 5 and the NCU 4,
A transmission control procedure for transmitting an image signal from the facsimile device to which the CPU 20 belongs begins (such reverse transmission is hereinafter referred to as reverse polling). and,
Based on a predetermined format, the CPU 20 sends character data indicating the reception status (for example, all pages received, up to the second page received, etc.) to the pattern generation circuit 12, and the character pattern (image signal) generated here is sent to the pattern generation circuit 12. is sent to the encoding unit 11.
The CPU 20 sends back the image signal indicating the reception status encoded and compressed by the encoding unit 11 via the modem control unit 5, modem 6, and NCU 4 (214). This allows the sender who communicated with the relay broadcast and the mailbox to grasp the message reception status at a glance.

Furthermore, during multi-copy communication, CPU2
0 sets the flag in the management table 101 corresponding to the multi-copy code data, and sets the file number data in which the received image signal should be stored.
Write 215 to the data column 108. Next CPU2
0 is file 1 corresponding to the above file number data
02 stores information such as the sender ID and the number of copies, and causes the DMA 14 to transfer the image signal (216). The CPU 20 enters a recording operation for the copy number data stored in the head of the file 102 (217). In other words, the CPU 20 stores the copy number data in the register of the RAM 21,
The DMA 14 is activated and controlled in the same way as in the case of the DMA 207. However, the CPU 20 receives end data from the DMA 14 every time one image signal transfer ends.
Decrease the data in the register by 1 and continue the same operation until the data becomes 0. During this time,
The CPU 20 checks 218 whether there is a paper shortage or a paper jam in the same manner as in the case 208 . In this way,
When there is no paper shortage or paper jam, and the recording output for the copy number data stored in the file 102 is completed, the flag corresponding to the code data of multi-copy communication in the management table 101 is reset, and the corresponding file number data is , the image signal is invalidated 219. As a result, the file 102 whose file number has been invalidated is made empty and can be used thereafter.

If the communication is not relay broadcast, mailbox, or multicopy, it is normal facsimile communication. At this time, the CPU 20 checks 220 whether there is a paper shortage or a paper jam, and if there is a paper shortage or a paper jam, a proxy reception operation is performed 221 as described in 209. In other words, the received image signal without being recorded is stored in a predetermined file 102, and the necessary management table 101 is created in the file 22.
2. In this way, when a recording output failure is detected before starting the normal reception operation, the CPU 20 saves the received image signal to the file 102 and creates the necessary management table 101 to resolve the recording output failure. This means that a recording output preparation process is performed in preparation for later recording output. Furthermore, if there is no paper shortage or paper jam at step 220, normal facsimile reception operation begins at step 223. For example, under the control of the CPU 20, the DMA 14 directly transfers the image signal output from the decoding section 10 to a buffer in the recording section 8, and the recording section 8 performs recording output based on this image signal. During this time, the CPU 20 checks 224 whether there is a paper shortage or a paper jam in the same way as in the case of 208, and if there is a paper shortage or paper jam, after detecting this, the CPU 20 processes the received image signal on behalf of the user as described in 221. 225, which becomes a receiving operation. Here, CPU
When a recording output failure is detected after the normal receiving operation is started, the image signal 20 saves the image signal after the recording output failure has occurred to the file 102, and creates the necessary management table 101. This means that a recording output preparation process is performed in preparation for recording output after the output failure is resolved.

In this way, in this embodiment, when the CPU 20 detects a recording output failure such as a paper shortage or a paper jam during normal reception when the own station is the destination in relay broadcast communication, the CPU 20 performs the following processing. It's functioning like.

Steps 201 to 203 determine whether to perform memory reception or normal reception.

When performing normal reception, the received image signal after the occurrence of a failure is stored in the storage means (RAM 13, disk 6).
2) to evacuate to 222, 225.

In preparation for recording output after the recording output failure is resolved,
209, 221, and 225 perform recording output preparation processing (creation of a management table) for image signals related to memory reception or image signals to be saved;

When such a receiving operation is being performed, a recording operation, which will be described next, may also be performed. Also, in Figures 4 and 5, when relay broadcast communication, mailbox communication, and multi-copy communication are used,
When a paper shortage or a paper jam is detected, and when substitute reception is started, the corresponding LEDs 27 to 32 are turned on.

(Recording Operation) The flowchart in FIG. 5 is a flowchart during recording. The CPU 20 executes the program shown in this flowchart both during the reception shown in FIG. 4 and after the reception end.

Is CPU 20 running out of paper or jammed?
Steps 301 to 304 to detect whether there is any unoutput in multi-copy, proxy reception, or mailbox communication. Here, there is a shortage of paper.
If a paper jam is detected, the CPU 20 controls the driver 24 to turn on the LED indicating the paper shortage/paper jam on the display unit 25, and waits for operator intervention.
Further, when there is unoutput in multi-copying, the CPU 20 lights up the corresponding LED in the same manner as described above, and performs recording output 307 in the same manner as in the case of 217 in FIG. 4. Also, 308 and 310 are the fourth
Since they are similar to 218 and 219 in the figure, their explanation will be omitted. Furthermore, when the CPU 20 detects a paper shortage or a paper jam, it lights up the corresponding LED, and when there is no paper shortage or paper jam and all the records have been output, the corresponding management table 101 and image signal invalidation processing 31 are performed.
0, and in this case indicates multi-copy
Turn off the LED.

Furthermore, when it comes to proxy reception, the CPU 20 turns on the corresponding LED (311) and checks (312) whether the copy switch is turned on. In other words, CPU2
0 detects whether the copy switch is turned on by scanning the input operation data of the switch provided in the operation section 23. If the copy switch is not turned on, the CPU 20 waits until it is turned on. The reason for doing this is as follows. Substitute reception occurs when there is a paper shortage or paper jam. For this reason, if recording and outputting is started without any intervention by the operator, recording and outputting may occur when the paper shortage or paper jam has not been completely repaired, and the paper shortage or paper jam may occur again.

When the copy switch is turned on, CPU20
searches the management table 101, reads out the image signal from the corresponding file 102 based on the file number data in which the substituted received image signal is stored (313), and performs recording output based on this image signal (314). The operation of the CPU 20 during this time has already been described, so it will be omitted. Thus, in this embodiment, recording output is performed on the condition that the copy switch is turned on, thereby making it possible to output recording after complete repair. For this reason, it is more preferable to take into account cases where the leading edge of the recording paper is distorted due to paper shortages, paper jams, etc., and copy after the copy switch is turned on a predetermined number of times or after a predetermined data input (for example, key switch operation). Recording is performed by turning on the switch. During this time, the CPU 20 is checking 315 whether there is any paper shortage or paper jam.
When the recording output of the full image signal is completed without any paper shortage or paper jam, the management table 101 regarding proxy reception communication is displayed.
The flag is reset and each data is invalidated (316). Turn off the LED indicating that there is interception reception 317. Furthermore, in the event of a paper shortage or paper jam during recording output based on the image signal that has been received on behalf of the user, an LED is lit to indicate this.

Also, in the case of mailbox communication,
The LED indicating mailbox communication is lit (319). Next, the CPU 20 waits 320 for input of predetermined data. Here, the predetermined data refers to data input by keying in a specific number from the operation unit 23, or by inserting a magnetic card in the case of a facsimile device capable of reading magnetic cards. When predetermined data is input, the CPU 20 compares this data with box number data related to mail box communication and checks 321 whether or not they match. When the data match, the DMA 14 executes processing to read out the image signal of the file 102 corresponding to the corresponding box No. data and transfer it to the recording unit 8 (32).
2. Recording output is performed based on this image signal 323. During this time, the CPU 20 checks whether there is a paper shortage or a paper jam (324), and if there is no paper shortage or paper jam and the recording output of all the image signals related to the mailbox communication is completed, the corresponding flag in the management table 101 related to the mailbox communication is reset,
Invalidate each data in the relevant file 102 (325), and turn off the LED display indicating that a message via mailbox communication has been received.3
26. Furthermore, in the event of a paper shortage or paper jam during recording output based on an image signal received through mailbox communication, an LED indicating this fact is lit.
Furthermore, in the above, if the specified data is input but does not match the box number, 32
1. The CPU 20 controls the driver 24 to display an input error message on the LCD 26 of the display unit 25 (327). Further, if there is no paper shortage or paper jam, and if there is no special communication 302 to 304, normal reception recording is performed 328. This normal reception recording operation is similar to steps 223, 224, and 225 in FIG. 4, and has already been described, so a description thereof will be omitted.

In this example, CPU20, DMA1
4. When a predetermined data is input (copy switch is turned on in the embodiment) after the recording output failure is cleared, the recording unit 8 functions to perform recording output based on the image signal subjected to recording output preparation processing.

(Transmission Operation) Next, the operation at the time of transmission will be explained with reference to FIG. The CPU 20 constantly scans the flags in the management table 101 in order to detect dial requests based on transmission time data while detecting dial requests input from the operation unit 23, checks the broadcast communication flag, and checks whether the flag is set. If so, the head of the file 102 is searched based on all the corresponding file number data (401). Since transmission time data is set at the head of the file 102, the CPU 20 detects whether or not there is a dial request based on this data. Here, the transmission time data is given by the method explained in FIG. 2 from the other party's facsimile device in relay broadcasting, and is given by the operation unit 23 in local broadcasting
It is input from. At this time, if there is no dial request (401), it is detected (402) whether there is a facsimile transmission request during normal transmission.

In the above, when there is a dial request, the CPU
20 controls the NCU 4 via the modem control unit 5;
Connection between NCU 4 and line 1 is established 403. Next, the CPU 20 uses the management table 10
1 and the transmission source data of the head of the file 102 to check whether it is local broadcast communication or not. Here, if it is not a self-station broadcast communication, it is similarly checked from the destination data whether it is a relay broadcast communication or not (405). If it is not a relay broadcast communication, the automatic dialing circuit 3
0 so that the dial signal is transmitted 407. As a result, the automatic dialing circuit 30 automatically dials the NCU based on the above-mentioned dialing data.
407 for outputting a dial signal via 407; When this is completed, the CPU 20 detects whether there is a facsimile transmission request (402). When the CPU 20 receives a facsimile transmission request, the dial signal has already been sent either by the dial key operation on the telephone 2 or by the operation in step 407, so the CPU 20 shifts to the normal facsimile communication operation (step 406).
In normal facsimile communication operation, the CPU 20 confirms that the other party has responded via the modem control unit 5 and NCU 4, sends and receives control signals via the NCU 4, and then sends and receives control signals to the reading scanning unit 9 and the encoding unit 11. ，
The DMA 14 is activated, and the image signal output from the reading scanning section 9 is sent to the encoding section 11 under the control of the DMA 14.
is transferred to, encoded and compressed, and then sent to the modem control unit 5,
Transmission is made via modem 6 and NCU 4.

If the analysis results 404 and 405 indicate whether or not it is a broadcast communication, the CPU 20 reads out one destination data from the head of the file 102 based on the corresponding file number data, and sends it to the automatic dialing circuit 30 for dialing. A signal is caused to be sent 408. Next, the CPU 20 controls the modem control unit 5,
It is checked via the NCU 4 whether or not it is busy based on the presence or absence of a busy tone, and it waits for a response from the other party's facsimile device (409). If there is a response
The CPU 20 sends and receives control signals for transmission control procedures via the modem control unit 5 and NCU 4, and
The DMA 14 is activated to read out an image signal from the corresponding file 102 in the RAM 13 or the disk 62, and is transferred to the encoding unit 11, and the encoded and compressed image signal is sent to the modem control unit 5, modem 6,
410, 411 transmitted via NCU4. CPU
20, while the transmission operation is being performed, it is checked 413 whether there is a transmission error based on a control signal or the like sent from the other party's facsimile device. When there is a transmission error, the trouble page is stored as management data 413. Further, if the image signals for all pages are correctly transmitted to one destination without any transmission errors, the transmitted data is stored as management data (414).

Next, the CPU 20 checks 415 whether or not there is an interrupt input by operating the reset key. In other words, in this embodiment, in the case of broadcast communication, interruption by the reset key is not allowed until one transmission communication to one destination is completed, and a series of pages are read and sent, and the receiving side records and outputs them. This is convenient when managing.

Next, the CPU 20 checks 416 whether all pages have been transmitted to the destinations of all the destination data stored at the head of the file 102. If transmission is not done to all destinations, CPU2
0, it is checked 417 whether transmission has been made a predetermined number of times to a destination to which complete transmission has not yet been made. If the predetermined number of calls have not been made, the process returns to 408 and continues the operation. Further, when the predetermined number of calls have been completed, the CPU 20 performs recording processing based on the management data (418). Further, the CPU 20 reads and records the image signal of the first page that should have been sent to the destination that has not been sent yet (419). If the recorded output of this image signal and the recorded output of the management data indicating the fact that the data has not been sent are combined to be recorded and output on one page, the first page that has not been sent will be clearly visible, which is convenient.

In the above embodiment, it is guaranteed that the RAM 13 and the disk 62 can sufficiently store image signals,
In other words, it contributes to the realization of various functions. Moreover, it is desired that various functions be realized in transmission and reception, so by separating the image signal storage area for transmission and the image signal storage area for reception (for example, in half), it is possible to perform only reception. It is preferable to avoid the situation where the entire area is used by the image signal and functions related to transmission cannot be realized. Also,
The CPU 20 monitors the amount of free space in the memory, and when the amount of space below a predetermined capacity is empty, it does not accept mailbox communications, relay broadcasts, etc., and does not accept local broadcasts. It would be convenient to prevent such reception and to warn the operator and prompt him to take appropriate action by lighting an LED or sounding an alarm.
Furthermore, when an area with a predetermined capacity or less is empty, it is possible to obtain the same effect as described above by not accepting image signals related to dithered halftones. At this time, a non-halftone image signal may be received and recorded and output.

In addition, each management data is managed collectively, and it is also possible to have it output as a consolidated record sheet, for example, by inputting specified data by an operator, or automatically (by program) at a specified time of the day. be.

[Effects of the Invention] As explained above, according to the present invention, it is possible to accurately deal with recording output failures during recording output, eliminate the need for troublesome operations such as retransmission, and eliminate wasteful communication. There is an effect. Furthermore, the image signal saved in the event of a recording failure can be easily and accurately identified, and can be read out and recorded while clearly distinguishing it from image signals stored for other purposes.
