Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile device using a telephone network, such as a sending-only type, a receiving-only type, a dual-purpose sending and receiving type, or a broadcasting device.

BACKGROUND TECHNIQUES Conventional facsimile equipment of this type has the ability to detect an abnormality caused by line conditions or malfunctions in procedures during communication, notify the operator via an alarm sound or an alarm lamp, and try again. There are known devices that have a function to prevent non-delivery by resending the correct original.

By the way, there are various cases of the abnormality, and there are cases where the receiving side is normal but the transmitting side is judged to be abnormal. In this case, since the receiving side does not have a function to determine whether or not the transmitted original has been correctly received, it is normal to start the facsimile call again and resend the original. Therefore,
In this case, there is a waste of recording paper for duplicate messages being ejected to the receiving side.

Problems to be Solved by the Invention As described above, although conventional facsimile devices are equipped with means for detecting abnormalities during communication, if a malfunction (abnormality) in the procedure is detected on the transmitting side, the receiving side In addition to the problem of not being able to avoid the generation of wasted paper due to duplicate records due to the lack of a function to check the status, in the case of important messages, it is necessary to contact the other party via telephone etc. based on duplicate records. In order to prevent confusion and accidents, there were problems such as cross-checking and other actions being required each time.

Therefore, the present invention was developed in view of the above-mentioned problems. When the transmitting side outputs a signal (retransmission signal) to the receiving side to retransmit the original after detecting an abnormality, the retransmission signal is received. The receiving side checks whether the reception status immediately before the abnormality is detected is from the same sender and whether it has ended normally, and if it has ended normally,
By starting the normal reception operation from the next page without recording the page in question, it is possible to prevent wasted paper due to duplicate recording as in the past, and when the retransmission signal is sent, the retransmission document ( To provide a facsimile device which eliminates the need for conventional acts such as cross-checking by both the sender and the receiver by adding characters and images to the front page of the reception record sheet to the effect that it is a retransmission. The purpose is to

Means for Solving the Problems In order to achieve the above-mentioned object, the present application provides a sending means for sending a retransmission signal notifying the retransmission of a document after detection of a transmission abnormality, and a first page of the retransmitted document when the retransmission process is started. a transmitter having a character pattern generating means for generating characters, images, etc. indicating that the retransmission is to be recorded in the transmission side; a detecting means for detecting the retransmission signal sent from the transmitting side; and a received message immediately before the retransmission signal is detected. A storage unit stores reception status including the transmission source, and upon detection of the retransmission signal, checks the reception status stored in the storage unit, and checks whether this is the same transmission source and normally received the received message immediately before the retransmission signal was detected. In this case, the present invention is characterized by comprising a receiving section having a control means for adding characters, images, etc. indicating retransmission to the next page and for starting normal reception operation from the next page.

Operation The receiving unit checks the reception status immediately before the abnormality was detected by the retransmission signal from the transmission unit, and if the reception status is from the same source and has ended normally,
Start recording from the next page without recording that page. Therefore, it is possible to prevent the generation of wasted paper due to duplicate recording as in the prior art.

Furthermore, when a retransmission number is sent out, if text and images indicating retransmission are added to the first page of the retransmission original, there is no need for conventional actions such as cross-checking by both parties.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

In order to simplify the explanation, a facsimile broadcasting device including a transmitter (a facsimile device for sending only), a facsimile device for receiving a receiver (a facsimile device only for receiving), and a transmitting/receiving function will be described below.

FIG. 1 is a schematic configuration diagram of a transmission-only facsimile device as an embodiment of the transmission section of the present invention, in which numeral 1 indicates a transmission control section consisting of, for example, a control microcomputer for controlling the entire device; Reference numeral 2 denotes a reading unit for originals (including resent originals), 3 a switch sensor, and 4a, 4b, 4c...4n a group of switches for mode selection, status selection, etc. provided on the panel. By operating these switches, Various functions are displayed on the panel via the switch sensor 3. This switch group 4a, 4b, 4c...
A retransmission instruction switch (for example, 4b) is additionally provided in 4n as a means for sending a retransmission signal to notify retransmission of a document after an abnormality is detected.

5 is a character generator, and this character generator 5 is connected to the retransmission instruction switch 4b.
When is pressed and the retransmission process is started, an additional note is added to the first page of the retransmitted manuscript (received message) (normally, the date and time the page was received, caller number, page number, etc. are automatically written). It has a function to generate text and images indicating that the transmission is being retransmitted.

Reference numeral 6 denotes a communication unit having a function of transmitting communication data (including retransmitted originals) to the receiving side (receiving unit).

The facsimile device having the above configuration has a known function of detecting an abnormality in the line condition or the like during communication.

FIG. 2 is a flowchart for explaining the operation of FIG. 1, and in the figure, ST1 to ST10 indicate steps of each operation process.

First, in ST1, switch groups 4a, 4b, 4c...
It is determined whether or not 4n has been pressed, and if any one has been pressed (YES), it is then determined in ST2 whether or not the retransmission instruction switch 4b has been pressed.

Here, if the retransmission instruction switch 4b is not pressed (NO), a normal facsimile procedure is executed. (ST3).

On the other hand, if the retransmission instruction switch 4b is pressed (YES), a retransmission facsimile procedure is executed. (ST4). That is, at the same time as the transmission control unit 1 starts communication with the other party's receiver (receiving-only facsimile device described later), it displays on the panel that it is a retransmission in the procedure, and starts the image sending phase (retransmission of original document). to go into. At this time, the retransmission indicator bit is set.

At the same time as entering the image sending phase, the transmission control section 1 first reads out text and images indicating retransmission from the character generator 5, and transmits them via the communication section 6 (ST5).

Thereafter, the same phases as before are executed. That is, in ST6, one page of images is transmitted, and it is determined whether this is normal or not. (ST7).

Here, if it is not normal, that is, if an abnormality is detected (NO), abnormal transmission termination processing is performed (ST8), and the process returns to ST1.

On the other hand, if it is normal (YE), it is determined whether there is a next page of the transmitted original (ST9).
If there is a next page (YES), the process returns to ST6 and repeats the process. If there is no next page (NO), normal transmission end processing is performed in ST10, and the process returns to ST1.

In this way, the transmitter (facsimile device for sending only)
When the retransmission instruction switch 4b is turned on, the retransmission bit is set and at the same time, characters and images indicating retransmission are read out from the character generator 5 and transmitted to the receiving side together with the transmission data.

These transmission data are received by the receiving section.
FIG. 3 shows a receiving-only facsimile device as an embodiment of this receiving section.

In FIG. 3, 7 is a reception control unit consisting of a control microcomputer, etc., for controlling the entire apparatus, and 8 is reception data (including retransmitted originals).
The recording unit 9 is a memory for storing the reception status immediately before abnormality detection, and is updated and recorded every time a received message or transmission source is received. Reference numeral 10 denotes a communication unit having a function of receiving retransmission indicator bits (retransmission signals) and other transmission data.

The operation of the apparatus having the above configuration will be explained with reference to the flowchart shown in FIG. Incidentally, in the figure, ST11 to ST21 indicate steps of each operation/process.

In ST11, the reception control unit 7 determines whether reception has started. If reception has started, then in ST12 it is determined whether the retransmission indicator bit is set. In other words, the retransmission indication (retransmission indication bit) displayed on the procedure is transmitted to the communication unit 10.
detects this and notifies the reception control unit 7 (YES), then in ST13 the reception control unit 7
reads the reception status immediately before the detection of the abnormality from the memory 9, and determines whether or not the previous communication (received telegram) has been normally received.

If the previous (previous) reception status has ended normally (YES), then in ST14, the contents of the memory 9 are checked to see if the previous transmission source and the current (at the time of retransmission) transmission source match. If they match (NO), reception processing is performed from the next page without recording the first page of the transmitted document at the time of retransmission (ST15). Here, duplicate recording is prevented, and the generation of wasted paper as in the conventional method is prevented.

If the retransmission indicator bit is not detected in ST12 (NO), or if normal reception was not performed previously in ST13 (NO), or if it is determined that the transmission source is different in ST14 (YES),
At the same time, the first page of the currently transmitted original (including when retransmitted) is received (ST16).

Next, in ST17, the reception control unit 1 determines whether or not the reception process has ended normally, and if it has ended normally (YES), information such as the status of the normal end and the transmission source is received. The information is stored and recorded in the memory 9 via the control unit 1 (ST19).

On the other hand, if it is determined in ST17 that the process has ended abnormally (NO), the fact that the transmission side has been notified of the abnormal end is recorded in the memory 9 (ST18), and the process returns to ST11.

Furthermore, when the process of ST19 is finished, then
It is determined whether there is a next page of the transmitted manuscript (ST20), and if there is a next page (YES),
Returning to ST16, the above-mentioned processes are repeated. On the other hand, if it is determined that there is no next page (NO), normal termination processing is performed (ST21), and ST11
Return to

In this way, by checking whether the retransmission indicator bit is set, the receiving section can determine whether the retransmission instruction switch provided in the transmitting section has been operated, that is, whether the received message currently being received is to be retransmitted. will be judged.

In addition, in the case of a retransmission original (telegram), the previous reception state read from the memory 9 and the current reception state are compared, and if the reception state (received telegram and transmission source) are the same, the retransmission original Waste of recording paper is avoided by discarding only the first page of the page without printing it out.

Note that if the reception status is different, text and an image indicating retransmission are added to the first page of the retransmitted document, and this is output from the recording unit 8.

FIG. 5 shows a schematic diagram of a facsimile broadcasting device according to another embodiment of the present invention.

This broadcasting device is equipped with a function to automatically send the same manuscript received by the sending side to multiple terminals, and when receiving a retransmitted manuscript from the sending side, it can also be used as a receiving unit and multiple terminals. When transmitting the received retransmitted manuscript to a location, each of these functions as a transmitting section.

In FIG. 5, reference numeral 11 denotes a broadcast control section comprising, for example, a control microprocessor system for controlling the entire apparatus, and has both the functions of a receiving section and a transmitting section. Reference numeral 12 denotes a reading section for image information (including resent originals) transmitted from the sending side, and 13 is an accumulation section for image information read by the reading section 12. This accumulation section 13 discards abnormal information based on errors. It has a function of selectively storing only normal information (in other words, it is possible to prevent wasted paper or duplicate recording). 14 starts the retransmission process,
It has a function to generate text and images that are added to the first page of the retransmission manuscript (received telegram) to indicate retransmission. Reference numeral 15 denotes a communication unit which handles calls to specified destinations, transmission of communication data to terminals, etc., and is equipped with a function of setting a retransmission indicator bit upon re-calling (means for sending a retransmission signal to notify retransmission of a document).

The operation of the broadcasting device having the above configuration will be explained with reference to the flowchart shown in FIG.
In the figure, ST22 to ST33 indicate steps of each operation and process.

If it is determined in ST22 that broadcast communication has started (YES), then in ST23 the reading section 12 reads the transmission data (image) from the transmitting side and stores all of this transmission data in the storage section 13. Next, the broadcast control unit 11 calls the specified destination (terminal) via the communication unit 15 (ST24). After that, the broadcast control section 11 reads the transmission data from the storage section 13, transfers it to the communication section 15, and transfers it to the communication section 15.
The pages are first broadcasted (ST25).

Next, it is determined whether the broadcast transmission for one page has been normally completed (ST26).

If it has ended normally (YES), it is determined whether this is the final page (ST27),
If it is not the final page (NO), the process returns to ST25, and the next page and subsequent pages are broadcasted. If it is the last page, normal termination processing is performed in ST28, and the process returns to ST22.

On the other hand, if it is determined in ST26 that the communication has not terminated normally, that is, if an abnormality during communication is detected (NO), the broadcast control unit 11 automatically performs abnormal termination processing (ST29). Next, the broadcast control unit 1
1 calls the abnormal termination destination via the communication unit 15 (ST30) and executes retransmission processing (ST31).
In other words, at this point, the same state as when the retransmission instruction switch 4b in FIG. death,
Enter the image sending phase (resending the original).

At the same time as entering the image sending phase, the broadcast control section 11 first reads the text and image indicating retransmission from the character generator 14, transfers them to the communication section 15, and sends them to each terminal (receiving section). Equivalent to)
(ST32).

Next, the broadcast control unit 11 reads the normal information (abnormality end page) immediately before the abnormality detection from the storage unit 13, and broadcasts it via the communication unit 15 (ST33). As a result, a recording paper (received telegram) with text and an image indicating retransmission added to the first page (abnormally ended page) of the retransmitted original is output to each terminal.

In this way, when the broadcast transmission of the abnormally ended page is completed (ST33), the process returns to ST26 and the process returns to ST3.
A judgment is made as to whether or not the process in step 3 has ended normally. If it has ended normally (YES), then ST27
If it is determined that it is not the final page (NO), the process returns to ST25, and the broadcast transmission of the next page and subsequent pages is executed in the same manner as described above.

Although FIG. 1 shows a sending-only facsimile device as a transmitting section, and FIG. 3 shows a receiving-only facsimile device as a receiving section, it goes without saying that the present invention can be applied to a facsimile device for both sending and receiving purposes. be.

Effects of the Invention As is clear from the above explanation, the present invention includes a transmitting unit equipped with means for transmitting a retransmitted signal, a receiving unit equipped with a retransmitted signal detecting means, and a means for checking the receiving state immediately before the detection to determine whether the signal is normal. If so, we added a means to start the normal reception operation from the next page (including the abnormally ended page), which prevents duplicate recording of received messages due to retransmission, saves wasted paper, and improves administrative processing. This has the effect of contributing to preventing mistakes.

Furthermore, if text and images indicating retransmission are added to the first page of the received message during the retransmission process, it is possible to eliminate the troublesome effort of verification by both the sender and the receiver.
