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 machines capable of memory reception are known. In this type of facsimile machine, the above two functions were thought to be independent, as is clear from the fact that the function to simultaneously record and output was not activated during memory reception, and conversely, the memory reception function was not activated when recording was output. .

[Problems in the background art] □For this reason, in the above-mentioned conventional facsimile machine, if there is a recording output failure such as a paper shortage or a paper jam during recording output, it is impossible to maintain the image signal at all, and the second signal must be retransmitted. I had no choice but to request it. For this reason, not only is the re-communication operation troublesome, but also when a recording/output failure occurs during recording/outputting, the same image signal is sent, resulting in wasted communication. 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.

[Object of the Invention] The present invention was devised in view of the drawbacks of conventional facsimile machines, and its purpose is to accurately cope with recording output failures during recording output, eliminate the need for troublesome operations such as retransmission, and
It is an object of the present invention to provide a facsimile device which can eliminate communication waste and can appropriately perform recording output after a recording output failure is cleared.

[Summary of the Invention] Accordingly, in the present invention, when a recording output failure is detected when recording output is performed based on the received image signal, the received image signal after the failure occurs is evacuated to the storage means, In preparation for recording output after the above-mentioned obstacle is cleared, recording output preparation processing is performed on the image signal stored in the storage means or the evacuated image signal, and predetermined data input is performed after the above-mentioned trouble is cleared. The above object is achieved by performing recording output based on the image signal subjected to the recording output preparation process.

As data other than the above, the CPU 20 is provided with incoming call data based on the detection of a calling signal and data indicating that communication is in progress based on the detection of DC loop formation with the line from the incoming communication detection circuit 7.

The facsimile device configured in this manner is capable of executing broadcast communication, mailbox communication, relay broadcast communication, 2-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 machine to a box with a desired number, the received image signal is stored in that box, and later sent to the box owner. This communication is designed to perform recording and output based on the received image signal when a predetermined operation input is made. 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 is stored in the memory, or the image signal is stored in the memory mentioned above. 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 can be performed after the problem is resolved. This is communication that makes it possible. Relay broadcast communication refers to the sequential broadcast communication of received image signals to destinations requested by the 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 the relay communication (transmission) 9 proxy reception communication, information indicating which type of communication is being sent and necessary information are provided from the other party's facsimile machine in the following manner.

One method is to include information in the NSS signal sent from the other party's facsimile machine (transmitter T), as shown in Figure 2 (A>).In this case, the necessary information is as follows.
In the case of relay communication, destination data is sent, in the case of mailbox communication, box order data is sent, and in the case of multi-copy communication, number of sheets data is sent. 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 machine send out the above information using a DTMF signal, as shown in FIG. 2(B). In other words, since the facsimile machine shown in FIG. 1 becomes the receiver R, the receiver 11R receives the CEDi, NSF. C3I and DIS signals are sent, and the transmission BIT
The operator hears this and operates the dial keys on the telephone, thereby transmitting the desired DTMF signal. For example, r#J rlJ is a mailbox, r*J rIJ is a relay broadcast, r#J r2
Set it to multi-copy by pressing J, enable the necessary information from the next 3rd digit using the numerical keys, and decide to indicate the end by "masu". This DTMF (number i) is received by the DTMF signal receiving circuit 81 via the NCU 4, and decoded data based on the DTMF signal is given to the CPLJ 20.C
When the PU 20 accepts this, it sends back an ACK via the NCLJ4, and when it does not accept it, it sends back a NACK. 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, receiver R to NSF, C3I.

When the DIS signal is sent out and the transmitter T side switches from the telephone to the facsimile machine and the send key is operated, the NSS and DO3 signals are sent out from the transmitter 111T, and the following is the same as in Figure 2 (A>). Transmission and reception of signals continues using the transmission control procedure.

Next, the CPLJ20 loads the RAM 13 or the disk 62.
FIG. 3 shows the relationship between the management table and files used to manage the data within. Here management table 10
1 is in RAM21, and file 102 is in RAM13.
or within 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. A flag column 107 is provided corresponding to each code data to indicate whether or not processing is required.
File N so that the file number data of the file to be further processed can be stored.

Data 1i 1108 (box number data is also stored in mailbox communication) is provided. When the RA) 113 or the disk 62 is accessed using the file number data as an address, the corresponding file can be read. In the head (first area) of the file 102,
Number of pages (number of original sheets).

The time to send, time to receive, sender ID (dial number), number of sheets to be recorded and output, trouble page, destination data, etc. are stored, followed by image signals. Therefore, when input for broadcasting, relay broadcasting, multi-copy, substitute reception, and mailbox communication are performed, the CPL 120 sets the flag in the corresponding flag column 107 and blanks the image signal, etc. The file number data of this file is stored in the corresponding file number.
Write to data column 10B. Further, the CPU 20 scans the flag column 107 at a predetermined period, reads the corresponding file number data when the flag is set, and accesses the file 102 based on this. Then, the CPU 20 immediately starts recording and outputting for multi-copy communication, and immediately starts communication for circular (including relay circular) communication if there is a time designation and if there is no time designation at that time. Regarding proxy reception communication and mailbox communication, if a predetermined operation is performed, recording and outputting is started. In addition, the management table 10 of the RAM 21
Areas other than 1 are used as registers and flags.

Next, referring to the flowcharts in FIGS. 4 to 6,
The specific operation of the CPU 20 will be explained.

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. The CPLJ20 receives the NSS signal from the other party's facsimile machine or the DTM
Information indicating which type of communication is being used and necessary information are obtained from the F signal.

Therefore, the CPU 20 refers to the information indicating which of the above communication types it is and checks whether it 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 read.

(204>. Next, CPLJ20 is the above file No.
Destination data, sender ID, etc. are stored in the file 102 corresponding to the data, and the image signal is transferred using the DMA 14.
(205>. If transmission time data is input, the CPtJ20 also saves that data to the file 102.
Store it in That is, the CPU 20 receives image signals from the modem control unit 5 and NCU 4 via buses 40, 50 and 70, except for receiving image signals! i Control signals are transmitted and received and necessary information is stored in the file 102 (when necessary, the path of the DTMF signal receiving circuit 81 and bus 90 is used). When it is time to receive an image signal, the CPU 20 activates the decoding section 10 and the DMA 14, passes the necessary data to the DNA 14, and transfers the necessary data to the bus 40.
The occupation of 50.70 is transferred to DMA14. by this,
The DMA 14 stores the image/signal decoded and expanded by the decoding unit 10 into a file 102 .

The CPL 120 also checks whether the own station is included in the destination data in the information obtained by any of the methods described in the explanation of FIG. 2 (206>, if the own station is included in the destination data). 2, the CPU 20 performs control so that recording output is performed based on the image signal of the file 102 (2).
07). In this case, the CPL 120 transfers control to the DMA 14 so that the image signal is 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 whether there is a paper shortage or paper jam based on the detection data sent from the paper shortage or paper jam detection circuit 82 (20B>. If there is a paper shortage or paper jam, the CPLI 2
0 sets the flag corresponding to the code data of 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 recording output is stored to the corresponding file number data Ill! i1
Register to 0B (209). In this way, CPLJ2
0 performs recording output preparation processing for the image signal stored in the file 102 for relay broadcasting in preparation for recording output after the recording output failure is cleared.

On the other hand, when the mailbox is received; the CPU 20 sets a flag in the management table 101 corresponding to the code data of the mailbox communication, and
Data (File No. Data) File No. Data 1
Write to li110B (210).

Next, the CPU 20 stores information such as the sender ID and destination name in the file 102 corresponding to the file number data, and causes the DMA 14 to transfer the image signal (211>. Next, the CPLJ 20 reads out necessary information from the head, creates box management data, sends it to the pattern generation circuit 12, generates a character pattern (image signal), and sends this character pattern (image signal) to the recording section 8. (212>. Recording output is performed in the recording unit 8 based on this character pattern (image signal). Fig. 7 shows a recording table 501 that is recorded and output. This recording table 501 includes, from the right side, source data, Mailbox No.

The destination, total number of pages, and reception time are printed.

This record sheet 501 is distributed to the recipient.

In communication between relay circulars and mailboxes, CPt
J20 is the information sent from the other party's facsimile machine (
, check whether there is data indicating a request in the reception list (2
13>. When there is data indicating a request in the reception list, the CPU 20 sends the modem controller 5. N.C.
A control signal indicating that the image signal is to be transmitted is sent via the LI 4, and a transmission control procedure for transmitting the image signal from the facsimile machine to which the CPLJ 20 belongs is entered (such inversion transmission is hereinafter referred to as inversion polling). And C.P.L.
Based on a predetermined format, J20 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 encodes the character pattern (image signal) generated here. conversion part 1
Send to 1. The CPU 20 sends the image signal indicating the reception status encoded and compressed by the encoding unit 11 to the modem control unit 5.
Modem 6 returns via NCLI 4 <214>.

This allows the sender who communicated with the relay relay and mailbox to grasp the message reception status at a glance.

Furthermore, during multi-copy communication, the CPU 20 stores the management table 101 corresponding to the multi-copy code data.
flag and writes the file number data in which the received image signal should be stored to the file number data l1108 (215>.Next, the CPU 20 writes the sender ID, number of copies, etc. to the file 102 corresponding to the above file number data. DMA1 stores the information and transfers the image signal.
4 (216>.CPU 20 executes file 10
The CPLJ 20 starts the recording operation for the number of copies stored in the head of No. 2 (217>. In other words, the CPLJ 20 stores the data of the number of copies stored in the register of the RAM 21, and writes the DMA
14 and performs the same control as in the case of 207. However, the CPU 20 uses the DMA 14 after each image signal transfer is completed.
The end data is received from , the data in the register is decreased by 1, and the same operation is continued until the data becomes O.

During this time, the CPLI 20 checks whether there is any paper shortage or paper jam in the same manner as in 208 (218). In this way, when there is no paper shortage or paper jam and the recording output for the number of copies 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, Processing is performed to invalidate the corresponding file number data and image signal (219>. As a result, the file 102 with the invalidated file number is made empty and becomes usable thereafter.

Check whether there is a jam in the relay broadcast, mailbox, or multi-copy (220>), and if there is any paper shortage or paper jam,
As explained in 09, the proxy reception operation is performed (221>).

In other words, the received image signal without being recorded is stored in a predetermined file 102, and the necessary management table 102 is stored.
1 is created (222), thus the CPU 20
When a recording output failure is detected before starting normal reception operation, the received image signal is saved to the file 102 and the necessary management table 101 is created, so that the recording after the recording output failure is cleared. This means that recording output preparation processing is performed in preparation for output. Furthermore, if there is no paper out or paper jam at 220, normal facsimile reception operation begins (2
23). For example, under the control of CPU U20, DMA1
4 directly transfers the image signal output from the decoding section 10 to the buffer 1 in the recording section 8, and the recording section 8 performs recording output based on this image signal. Check whether there is a paper shortage or paper jam (224), and if there is a paper shortage or paper jam, after detecting this, the received image signal will be substituted for reception as described in 221 (225). . Here, the CPU 20 performs normal reception operation. After that, if a recording output failure is detected, the image signal after the recording output failure is saved to file 1.
02 and the necessary management table 101.
By creating this, a recording output preparation process is performed in preparation for recording output after the recording output failure is resolved.

As described above, 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,
It works like this: .

Determine whether to perform memory reception or normal reception (2
01-203).

When normal reception is being performed, the received image signal after the failure occurs is saved in the storage means (RAM 13, disk 62) (222, 225>).

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

When such a receiving operation is being performed, a recording operation, which will be described next, may also be performed. In addition, in FIGS. 4 and 5, when relay communication, mailbox communication, or multi-copy communication occurs, when a paper shortage or paper jam is detected, or when proxy reception occurs, the corresponding LE0
27 to 32 are lit.

(Recording Operation) The flowchart in FIG. 5 is a flowchart at the time of recording. The CPLJ 20 executes the program shown in this flowchart both during the reception shown in FIG. 4 and after the reception is completed.

The CPL 120 detects whether there is a paper shortage or paper jam, whether there is any unoutput in multi-copying, whether there is proxy reception, or whether there is mailbox communication (301 to 304). Here, if a paper shortage/paper jam is detected, the CPLJ 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 ED in the same manner as described above, and performs recording output in the same manner as in the case of 217 in FIG. 4 (307). Furthermore, since 30B and 310 are the same as 218 and 219 in FIG. 4, respectively, their explanation will be omitted. Furthermore, when the CPU 20 detects a paper shortage or a paper jam, it turns on the corresponding LED, and when there is no paper shortage or paper jam and all the records have been output, it performs invalidation processing (310) for the corresponding management table 101, image signal, etc. At this time, the LED indicating multi-copy is turned off.

In addition, when it comes to proxy reception, the CPU 20 turns on the corresponding LED.
lights up (311) and checks whether the copy switch is turned on (3'12>. In other words, the CPU 20 scans the input operation data of the switch provided in the operation section 23 and turns on the copy switch. Detection. If the copy switch is not turned on, the CPU 20 will wait until it is turned on. The reason for doing this is as follows. Proxy reception is performed when there is a paper shortage or a paper jam. For this reason, if you start recording and outputting without any intervention from the operator, the recording will be output when the paper shortage/paper jam has not been completely repaired, and the paper shortage/paper jam may occur again. It is from.

When the copy switch is turned on, the CPU 20 searches the management table 101 and selects the file number (corresponding) based on the file number data in which the substituted image signal is stored.
The image signal is read out from the filter 102 (313), and recording output is performed based on this image signal (314). C during this time
The operation of Pu20 has already been described, so a description thereof will be omitted. Thus, in this embodiment, by executing recording output on the condition that the copy switch is turned on, it is possible to output recording after complete repair. For this reason, it is more preferable to take into account the case where the leading edge of the recording paper is distorted due to paper shortage, paper jam, etc., and after turning on the copy switch a predetermined number of times.
The data is recorded and output when the copy switch is turned on after a predetermined data is manually operated (for example, by operating a key switch).

During this time 1. CPLI20 checks whether there is any paper shortage or paper jam (315). I am completely confident that there is no paper shortage or paper jam.
When the recording output of the number is completed, the flag in the management table 101 regarding proxy reception communication is reset, each data is invalidated (316), and the LED indicating that there is proxy reception is reset.
turns off (, 317). Furthermore, based on the image signal that has been received as an alternative, if there is a paper shortage or a paper jam during recording output, an LED is lit to indicate this.

Furthermore, if the communication is a mailbox communication, an LED indicating that the communication is a mailbox communication is lit (31
9). Next, the CPU 20 has input of predetermined data (3
20) Here, the predetermined data refers to data input by manually pressing a specific number key from the operation unit 23, or by inserting a magnetic card in the case of a facsimile machine that can read magnetic cards.

When predetermined data is input, the CPU 20 compares this data with the box number data related to mailbox communication and checks whether they match (321).

When the data match, the DMA 14 executes a process of reading out the image signal of the file 102 corresponding to the corresponding box number data and transferring it to the recording unit 8 (322), so that the recording output is performed based on this image signal. (32
3). 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 and output of the commands related to the mailbox communication is completed, the corresponding flag in the management table 101 related to the mailbox communication is changed. , reset, and invalidate each data in the corresponding file 102 (325), and turn off the ED display indicating that a message via mailbox communication has been received (326). Further, in the case of a paper shortage or paper jam during recording output based on an image signal received through mailbox communication, an LED indicating the fact is lit. Furthermore, in the above, if the predetermined data is input but does not match the box number (321>, the CPLJ 20 controls the driver 24 to display an input error on the LCD 26 of the display unit 25 ( 327).If there is no paper out, paper jam, or any of the special communications (302-304), normal reception recording is performed (32B>).This normal reception recording operation is performed at 223.3 in FIG. 224, 22
This is the same as 5 and has already been described, so the description will be omitted.

As described above, in this embodiment, when a predetermined data is input (in this embodiment, the copy switch is turned on) after the recording output failure is cleared, the CPLI 20, DMA 14, and recording unit 8 perform recording output based on the image signal that has been subjected to recording output preparation processing. It functions as it does.

(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 to detect dial requests based on transmission time data while detecting dial requests input from the operation unit 23, checks flags for broadcast communications, and determines whether the flags are set. Sometimes, the head of the file 102 is searched based on all the corresponding file number data (401
). Since transmission time data is set in the head of the file 102, the CPLJ 20 detects whether or not there is a dial request based on this data. Here, the transmission time data is given from the other party's facsimile machine using the method explained in FIG. 2 in the relay call, and is input from the operation unit 23 in the call to the own station. At this time (401), if there is no dial request, it is detected whether there is a facsimile transmission request during normal transmission (
402>.

In the above, when there is a dial request, the CPU 20 controls the NCU 4 via the modem control section 5 to establish a connection between the NCU 4 and the line 1 (403). Next, the CPLJ20 has a management table 101 and a file 102.
It is checked whether or not it is local broadcast communication by referring to the transmission source data of the head of (aOa).

Here, if it is not a relay broadcast communication to the own station, it is similarly checked from the destination data whether it is a relay broadcast communication (405>).

If this is not a relay communication, the automatic dial circuit 30 is controlled based on the dial data input from the operation unit 23, so that a dial signal is sent (
407). Thereby, the automatic dialing circuit 30 outputs a dialing signal via the NCLJ4 based on the dialing data (407). When this is finished, the CPU
20 detects whether there is a facsimile transmission request (4
02).

When the CPU 20 receives a facsimile transmission request,
Since the dial signal is sent either by the dial key operation of the telephone 2 or by the operation at 407,
The routine then proceeds to normal facsimile communication operation (406). In normal facsimile communication operation, the CPU 20 operates the modem control unit 5. Check that the other party has responded via NCLJ4,
After transmitting and receiving control signals via the NCU 4, the reading operation section 9, the encoding section 11. Start DMA14, and
The image signal output from the reading operation section 9 is transferred to the encoding section 11 under the control of the modem control section 5.4, where it is encoded and compressed. Transmission is made via the modem 6 and NCU 4.

When the analysis result (404, 405) indicates whether or not it is a broadcast communication, the CPLJ 20 reads one destination data from the head of the file 102 based on the corresponding file number data, and gives it to the automatic dialing circuit 30 for dialing. A signal is sent out (408). Next, C.P.
LJ20 is the modem 1lJIj section 5. It checks whether it is busy based on the presence or absence of a busy tone via NCLJ4 and waits for a response from the other party's facsimile device (409).
). When there is a response, the CPU 20 controls the modem control unit 5. NCU
At the same time, the DMA 14 is activated to read an image signal from the corresponding file 102 in the RAM 13 or the disk 62, and transfer it to the encoding unit 11 for encoding and compression. The image signal is transmitted via the modem control unit 5, modem 6, and NCU 4 (410, 411, and the CPU 20 detects transmission errors based on control signals sent from the other party's facsimile machine, etc.) while the transmission operation is being performed. Check whether there is one (4)
13). When a transmission error occurs, the trouble page is stored as management data (413). Also,
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 whether there is an interrupt input by operating the reset key (415). In other words, in this embodiment, in the case of broadcast communication, transmission (
A series of pages are sent successively without allowing any interruption by the reset key unless a communication (1 communication) is completed, which is convenient when managing recording output on the receiving side.

Next, the CPU 20 checks whether all pages have been transmitted to the destinations of all destination data stored in the head of the file 102 (416).

If the transmission is not made to all destinations, CPLI2
0 checks whether or not a predetermined number of calls have been made to a destination to which complete transmission has not yet been made (417).

If the predetermined number of calls have not been made, the process returns to 408 and continues the operation. Furthermore, when the predetermined number of transmissions have been completed, the CPLJ 20 performs recording processing based on the management data (41B>.Furthermore, the CPU 20 records the image signal of the first page that should have been sent to the untransmitted destination. Read and record output (419).The record output of this image signal and the record output of the management data indicating that it has not been sent are combined to 1.
It is convenient to record and output the first page that has not been sent.

In the embodiments described above, it is ensured that the RAM 13 and the disk 62 can sufficiently store image signals, contributing 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, CPU20
monitors the amount of free space in the memory, and when the amount of space below the predetermined capacity is empty, it will not accept mailbox communications or relay notifications, and will not accept notifications related to its own station. Please refrain from doing this, and
It is convenient to warn the operator and prompt him to take appropriate action by lighting up the ED 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 dither 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 on -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. Moreover, there is an effect that the recording output after the recording output failure is cleared can be appropriately performed after inputting the predetermined data.
