Abstract

PURPOSE:To prevent communication cost and recording paper from being wasted by storing information showing the number of untransmitted originals together with untransmitted picture signals when transmission error is generated in the middle of communication, transmitting only untransmitted originals in the case of retransmission and adding a message to the first original based on the information showing the number of untransmitted originals. CONSTITUTION:A main body 1 of the facsimile store and forward exchange is connected through a line 15 to a network 20, and facsimile equipments 301-30n are connected to the network 20. On the other hand, a printer 12 and a CRT display device 13 are connected to the main body 1. In this case, when transmission error is generated in the middle of communication, the information showing the number of untransmitted originals is stored together with the untransmitted picture signals, the untransmitted originals are transmitted in the case of retransmission, and the first original is transmitted after being added the message based on the information showing the number of untransmitted originals so that the transmission of the untransmitted original can be clear on the reception side. Thus, the communication cost and the recording paper can be prevented from being wasted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile storage device that stores and then transmits image signals corresponding to a document image.

(Prior Art) Conventionally, in facsimile systems, when a failure occurs during transmission, the sending side displays the cause of the failure on an external display output means such as a CRT display device or a journal printer. - On the other hand, although the receiving side is aware that a disturbance has occurred, it is usually not noticed, especially when the automatic reception mode is set.

Therefore, a type of facsimile machine that reads all set originals, stores them in memory, and then sends them, or a facsimile machine that receives an image signal related to the original from the facsimile machine, stores it in memory once, and then delivers it to the other party at a predetermined time. A type of facsimile storage/exchange device uses image signals stored in a memory to transmit image signals for all pages.

However, such a facsimile storage device not only increases communication costs, but also causes the problem that recording paper is wasted because the receiving side receives and records the original of the page that has already been received again. was.

(Problems to be Solved by the Invention) As described above, according to the conventional facsimile storage device, even if a transmission error occurs during facsimile transmission, the image signal stored in the memory is used to start the process from the beginning. Since the image signals of all pages of the document are transmitted, problems arise in that communication costs increase and recording paper is wasted.

The present invention has been made to solve the problems of the conventional facsimile storage device, and its purpose is to eliminate the waste of communication costs and recording paper in the event that a transmission error occurs during the transmission of a document. To provide a facsimile storage device in which all pages of original documents can be collected and delivered to a recipient.

[Structure of the Invention] (Means for Solving the Problems) Therefore, the present invention provides a storage means for storing image signals corresponding to a document image, and a method for transmitting the image signals stored in the storage means during communication. A transmission error detection means detects a transmission error, and the transmission error detection means detects the number of untransmitted originals until the transmission error is detected, and the information on the number of untransmitted originals is transmitted together with the image signal of the unsent originals. a transmission error processing means for accumulating in the image signal accumulating means; when a transmission request occurs, detecting whether or not an image signal of a document related to the transmission request is accumulated together with information on the number of untransmitted sheets;
If the information has not been stored, the image signal of the original is transmitted, while if the information has been stored, the image signal of the message is created based on the information on the number of untransmitted pages and sent first. A facsimile storage device is provided with an image signal transmitting means for transmitting an image signal superimposed on the image signal of the first page of an untransmitted manuscript.

(Function) According to the above configuration, when a transmission error occurs during a call, the information on the number of untransmitted sheets is accumulated together with the unsent image signal, and when retransmitting, the unsent original is sent and the first original is sent. A message based on the information on the number of unfinished sheets is added and transmitted, and it becomes clear on the receiving side that an untransmitted manuscript has been sent.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 shows a facsimile system constructed using a facsimile storage and forwarding device as a facsimile storage device. The main body 1 of the facsimile storage and forwarding device receives If! via a line 15! ! Connected to 20! ! 420 includes facsimile machines 301 to 30. is connected. The communication system part 2 of the main body 1 is connected to the line 15. The communication control section 2 is connected to a main control section 3, and the main control section 3 is connected to an accumulation section 10 in which image signals are accumulated, and an interface 11 to which a printer 12 and a CRT display device 13 are connected. The main control unit 3 includes a CPU 4 that controls the entire device.
, a main memory 6 storing data and programs used by the CPU 4, a sub-memory 7 used as a working memory, a transmission error detection means 5 for detecting transmission errors during facsimile transmission, a counter 8, and a character generator 9. . As shown in FIG. 2, the communication control unit 2 of this facsimile storage and forwarding device is on the transmitting side, and after transmitting, for example, the CCITT recommendation T and series image signal PIX, it sends a control signal RTC (Return to Control). When one page of the original is completed, a control signal MPS (multi-page signal) indicating transportation is sent. Therefore, when the receiving side receives the signal normally, a control signal MCF (message conformation) is sent from the receiving side, so the transmission error detection means 5 detects this and performs error detection. The counter 8 is incremented to count the number of sheets to be transmitted. In addition, the main memory 6 also contains a message for sending the remaining originals if the transmission is incomplete, such as, ``There has been a problem with the serial number slot, so we will resend the remaining originals from Ropage. Please take a look at the manuscript that has already been sent.'' is stored. The character generator 9 converts the above code and the numerical code indicated by the mouth into an image signal and outputs the image signal.

The main memory 6 of the facsimile storage and forwarding device configured as described above stores a program shown in the flowchart shown in FIG. 3, and is executed at the time of transmission. In this facsimile storage and forwarding device, facsimile units W301 to 30
An image signal related to the original document and its destination are sent from n, so a serial number (communication number) is attached to the signal, destination information etc. are stored in the sub-memory 7, and the image signal is stored in the storage section 10. At this time, if a time is specified, a timer is set and a transmission request interrupt is made. In this way, image signals are received and received, and the flowchart of FIG. 3 starts when the system is started up, and the CPU 4 detects whether there is a transmission request interruption (301). When there is a transmission request, it is checked whether the document related to the transmission request is a new transmission based on the reset of the retry flag in the submemory 7 (302).

If it is a new transmission, a serial number is assigned to each destination (303), the communication control unit 2 is made to make a call based on the destination information in the sub-memory 7 (304), and it is detected whether there is a response (303).
05). If the process ends without a response, a serial number and a flag indicating a retry are set in the submemory 7, journal information is created, and the information is sent to the printer 12 via the interface 11.
output from and display on the CRT display device 13 (
306). On the other hand, when there is a response, the image signal of the first page is read out from the storage section 10 and given to the communication control section 2 for transmission (307). Then, reset counter 8.
08) Make the transmission error detection means 5 perform error detection (
309). If no error occurs, the end of transmission for one page is detected by the presence or absence of reception of the control signal MCF, the counter 8 is incremented by "1" (310), and it is detected whether one communication is completed (311).

If one communication is not completed and there is a document to be transmitted, the image signal of the next page of document is transmitted (312) and the process returns to step 309. When one communication is completed, journal information of the communication is created, output from the printer 12, and displayed on the CRT display device 13, and information in the sub-memory 7 and image signals in the storage unit 10 that are no longer needed are invalidated ( 313) End.

On the other hand, if an error is detected during document transmission (309), it is detected whether a retry is required (314), whether a retry is necessary, that is, whether a transmission error occurred after all image signal transmission has been completed, etc. If the attempt is not necessary, communication management information indicating an error is output to the printer 12 and CRT display device 13, and a journal indicating the end of transmission is output (315).

If a retry is necessary, information on the number of untransmitted sheets is created from the count number of the counter 8 and information on the number of original sheets in the submemory 7, a retry flag is set, and the submemory 7
A journal indicating the transmission results is stored in the printer 12,
It is output from the CRT display device 13 (316).

On the other hand, if the retry flag is detected to be set in step 302, which detects whether it is a new transmission after transmission request detection (301), information is retrieved from the submemory 7 (317), and the original is sent depending on the presence or absence of information on the number of untransmitted sheets. It is detected whether an error has occurred before the process starts (318). If it is detected that this is due to an error before sending the original, the process proceeds to step 304, and the same processing as for new sending is performed. On the other hand, when more than one page is being sent, the number (number of pages) indicated verbally for the above-mentioned message is calculated based on the information on the number of unsent pages and the information on all pages, and the number of pages in the main memory 6 is calculated. It is inserted into the code and given to the character generator 9, superimposed as an image signal on the upper end portion 401 of the image signal of the document 400 to be transmitted this time as a message M as shown in FIG. 4, and waits for transmission (319).

When such a document is transmitted, as is clear from FIG. 4, it can be seen that the remaining document that was relayed last time is being sent on the receiving side. Note that the sender, serial number, etc. may be included in the message M as before. Also message N
The insertion position (①) may be at the lower end or side end.

[Effects of the Invention] As explained above, according to the present invention, when a transmission error occurs during communication, information on the number of unsent images is accumulated together with unsent image signals, and when retransmitting, information on the number of unsent images is stored. Only the original is sent, and a message based on the information on the number of unsent pages is added to the first original before being sent. This makes it clear on the receiving side that this is a continuation of the original that has not been sent, and saves communication costs and recording paper. This makes it possible to eliminate waste.
