Abstract

PURPOSE:To inform the receipt of a transmission picture to a sender by providing a means informing the end of an output of a memory reception picture to the sender side. CONSTITUTION:A procedure signal and a picture data sent through a line 6 are demodulated by a communication control section 4 and decoded/analyzed by a main control section 1. In case of memory reception, the result of decoding is used only for the discrimination of the propriety of reception and the main control section writes a demodulation data as it is together with other control information obtained by the procedure signal in a picture memory 20 as a file. The file is closed when a control flag 20a is set at the end of communication. Then the line is once interrupted, a sender station stored in the file is called, the communication line is connected again to check whether or not a flag A is set. When the flag is set, the normal reception is noticed and if not set, the abnormal reception is informed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a communication device for image data, coat data, etc., which has a memory reception function.

[Prior Art] Conventionally, in communication with this type of memory receiving device, even in the case of memory reception, reception is performed using the same procedure as normal recording paper reception, and the sending side receives a page end signal ( M.P.S.

Receiver response signal (MCF, EOM, EOP)
(RTP, RTN), it is only determined whether the transmitted image has been correctly stored in the memory.

[Problem to be solved by the invention] However, in the above conventional example, only the result of memory reception is notified to the sending side, so it is impossible to determine whether the information was printed on the recording paper and transmitted to the recipient. there were.

In addition, receivers also have the disadvantage that if a period of time passes without printing, the available image memory decreases and new memory cannot be received.

[Means and effects for solving the problems] The present invention is capable of notifying the sender of the reception of the transmitted image by providing a means in the receiver for notifying the transmitting side of the end of outputting the memory received image. The purpose is to provide communication equipment.

Another aspect of the present invention is to provide a communication device capable of notifying the sender of non-delivery of the transmitted image by providing a means for notifying the transmitting side when the received image is not output after completion of reception in the receiver. It is an object.

[Embodiment] FIG. 1 shows an embodiment of the present invention, and 1 to 8 are main components of a facsimile machine. 1 is a main control unit consisting of CPU control memory, etc., 2 is a reading unit, 3 is a recording unit, 4 is a communication control unit, 5 is this telephone, 6 is a communication line, 7 is an operation unit such as a keyboard, 8 is an LCD This is the display section by et al. Reference numeral 20 denotes an image storage memory (hereinafter referred to as image memory), which clearly represents the features of the present invention. Figure 2 shows the details.

The image memory is stored as one file for each communication,
Each file includes a file control flag 20a that indicates whether the file is valid/invalid and the file type, a transmitter reception number register 20b, a confidential box number register 20c for confidential reception, a transmitting station telephone number register 20d, and a reception date and time register. 20e, and a received image storage 20f.

Next, in the reception operation in the above configuration, the procedure signal and image data transmitted through the line 6 are demodulated by the communication control section 4, and decoded and analyzed by the main control section 1. In normal recording paper reception, the main control section 1 directly sends the decoding result of image data to the recording section 3 for recording. On the other hand, in the case of memory reception, the decoding result is only used to determine whether the reception is good or bad, and the main control section stores the demodulated data as it is in the image memory 20 along with other control information obtained from procedure signals, etc. write to file. The file is closed by setting the communication end control flag 20a.

Confidential flag 20a and transmitter reception number 2 as control information
0b, the confidential box number 20c is set to the NSC signal, and the transmitting station telephone number 20d is set to the proxy flag 2 by the TSI signal.
0a, 20e at the receiving port depends on the state of the receiver.

When outputting the memory-received image, the operator specifies an output file by operating predetermined keys for confidential and proxy files on the operation unit 7. The main control section 1 searches for a specified file, decodes the image data, and outputs it to the recording section 3 for recording.

In the conventional example, the file is cleared when memory image output ends. In this embodiment, processing at the time of outputting a memory image is performed as follows.

■ Creating reply image data as shown in Figures 3 and 4 ■ Making a call based on the transmitting station phone number ■ Sending a reply image ■ Clearing the memory image file When multiple files are output at once For each file Perform ■～■.

Furthermore, in a device in which image data is stored in a volatile memory and file control information is stored in a nonvolatile memory, if the image data is lost due to a power cut, each transmitting station may be notified accordingly.

Figure i5 shows a control flowchart of this embodiment. A control program for executing the flow shown in FIG. 5 is stored in the ROM in the main control section l shown in FIG.

In FIG. 5, in step Sl, control data such as the transmitting station telephone number, confidential box number, transmission date and time, and the image signal are stored in a file.

Then, in step S2, M
Send CF or RTN and temporarily disconnect the line.

Then, in step S3, a timer is started, and in S4, it is determined whether or not there is a memory copy instruction for each file. If memory copy is not instructed even after a predetermined period of time,
Alternatively, the flag A is reset if the memory copy instruction has been issued within a predetermined time, but the memory contents have been erased, the printer is malfunctioning, or the printing has not been performed normally. On the other hand, if it is printed on the main room, flag A
is set (S5). Then, in step S6, a call is made to the transmitting station stored in the file, and the communication line is reconnected. In step S7, it is checked whether flag A is set, and if it is set, a notification of normal reception as shown in Fig. 4 is given, and if it is not set, a notification of abnormal reception is given as shown in Fig. 3. be. When the notification ends, S
Step 8 to clear the file, step S9 to disconnect the line.

In this embodiment, the memory is cleared even when the printer is abnormal, but it is also possible to retain the memory contents when the printer is abnormal, and after the printer returns, print and issue a normal reception notification.

Further, if the recipient's name is registered in correspondence with the confidential box, that item may be added to the reply image.

Further, when notifying the end of output, information may be transmitted only by a procedure signal without transmitting an image, and the transmitter a may display and print the information based on the information.

As explained above, the performance of confidential transmission/reception/proxy reception can be easily improved by sending the end of output of memory reception back to the transmitter.

Furthermore, by clearing a received image file that has passed a certain period of time since it was received in the memory and notifying the corresponding transmitting station, there is an effect that effective use of the memory in the receiver and research on information transmission at the transmitting station can be realized at the same time.

Note that the present invention is applicable not only to image communication but also to communication devices capable of character code data communication and the like.

[Effects] As described above, according to the present invention, it is possible to notify the sending side at the time of memory reception whether or not the contents received from the memory have been accurately printed out.
