Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a memory transmission function.

[Conventional technology]

In the conventional memory transmission, the image memory is deleted regardless of whether the communication ends normally or an error. The main reason is to use limited memory efficiently.

 FIG. 6 shows a flow of the conventional example.

As shown in the flow chart of FIG. 6, the image data is deleted only when the communication is completed.

However, the image data having a communication error can be stored in the memory due to the large capacity of the memory. For example, as disclosed in Japanese Patent Application Laid-Open No. 61-276475, it is known that when a communication error occurs, image data is repeatedly read from a memory and retransmitted until normal transmission is possible.

[Problems to be Solved by the Invention] However, in the technique disclosed in the above publication, when a line is disconnected due to a communication error, the line connection is restarted immediately, and retransmission is repeated many times until the transmission ends normally. Therefore, not only other processing cannot be performed during that time, but also since the communication error occurs immediately, there is a high possibility that the same error will occur again and the number of retransmissions will increase.

An object of the present invention is to provide a facsimile apparatus in which the above-mentioned problems have been eliminated, and an object of the present invention is to improve the processing efficiency by retransmitting data having a communication error at an arbitrary time.

[Means for Solving the Problem (and Action)] In order to achieve the above object, the present invention provides a memory capable of storing a plurality of data, a means for assigning a reception code to the data stored in the memory, Transmitting means for transmitting the data in the memory to the destination, identifying means for identifying the transmission result transmitted by the transmitting means, and holding the data identified as a communication error by the identifying means in the memory; Control means for selecting, from a plurality of data in the memory, data which has caused a communication error due to manual input of the received reception code, and reading and retransmitting the data.

By adopting this configuration, data having a communication error can be selected from the memory by manual input of a reception code, read out, and retransmitted.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the facsimile apparatus of the present embodiment.

Reference numeral 1 denotes a control unit for controlling the entire apparatus, which includes a microcomputer and peripheral devices of the microcomputer such as a ROM and a RAM storing a control program. Reference numeral 2 denotes a recording unit for printing a received image, 3 denotes a reading unit for reading an original, and 4 denotes an operation unit for an operator to operate the apparatus. The operation unit includes a liquid crystal display and a key input switch. Reference numeral 5 denotes a transmission / reception unit, and reference numerals 6 and 7 denote storage units composed of RAMs. Reference numeral 6 denotes a storage for various management information. Reference numeral 7 denotes an image memory. .

Reference numeral 24 in FIG. 2 shows a data format in the storage unit A of this embodiment. A plurality of possible image memories are considered as one file, and a table of file management information corresponding to the number of existing files is created as shown in FIG.

21 shows the contents. The valid data bit of the head management flag is for determining whether the following data is valid.

The next reception number is a serial number given by the control unit 1 to each file.

When an operator stores a document in a memory, the document is displayed on a liquid crystal display (or a display such as an LED) of the operation unit 4.
It is set as management information. Thereafter, when the operator designates a desired file, this file is used.

The file storage destination information is the storage location of the image data, and if the actual address or the image area is divided into physically fixed-length blocks, the number of the block used is set. Reference numeral 25 denotes a data format in the storage section B in which actual image data is stored. As shown in FIG. 22, a file mode (total number of pages, etc.) is set at the head, and page information is set for each of the accumulated pages.

Details of the page information are shown in FIG. In the page mode, the width in the main scanning direction, the density in the sub scanning direction, and the like are set.

The unexecuted flag is set to “1” when the memory is stored, and when the page is transmitted normally (in the case of the T30 procedure of the CCITT recommendation, the procedure end EOP, message end EOM, and the Q signal of the multi-page MPS are executed in a post procedure) Is set to "0" (when a message confirmation MCF signal is received). That is, if the transmission is not performed normally, the unexecuted flag remains “1”.

Next is the value of the page. For example, the value 7 is set for the seventh page.

In the next page storage destination information, the head address of the page information of the next page is set, and then the image information is stored.

FIG. 3 is a flowchart showing the control operation of the control unit 1 of the present embodiment. Hereinafter, description will be given with reference to the flowchart of FIG.

 In this control, the following three control variables are used.

(Present in the storage unit A) P _all : Total number of pages P _CNT : Transmission page counter P _ok : Normal end page counter First, when an operator specifies a destination and stores the document in the memory, a reception number is given (for example, “ 1234 "), the file management information shown at 24 in FIG. 2 and the format file shown at 25 are created. Here, the 23 unexecuted flags are “1” for all pages.

First is substituted into P _all read the total number of pages from 22 file mode of the step S1 Figure 2.

Next, variables P _CNT and P _ok are cleared to zero in step S2.

Next, in step S3, the previously designated destination is dialed.

 Then, in step S4, the response of the other party is detected.

If the other party's response signal (digital identification DIS signal in T30 procedure) is detected in step S4, the pre-procedure is performed in step S5, the page with the unexecuted flag = 1 is searched in step S7, and the page is searched in steps S8, S9, S10. Submit the page.

In the post-procedure of the next step S11, a response to the Q signal is detected, and when the MCF signal is received, in steps S12 and S13, it is assumed that the page has been successfully transmitted, and the unexecuted flag of the page is set to "0" ( In step S14), _Pok is _incremented by 1 (step S15). In step S16, it is determined whether or not the document is the last one. If there is a next page, the process returns to step S5 to transmit the next page. The storage location of the next page is the page information 23 in FIG.
I understand more.

In addition to excisional to P _all to calculate the error page number in the step S17, to erase the image memory as has been transmitted all pages successfully in the step S19 if the P _all is "0" at step S18.

To erase the image memory is to set the valid data bit of the file management information in FIG. 24 to "0". In addition, the image area of FIG. 25 may be filled with unintended data (for example, “0”). Redial count is over (Step S21)
Or the other party's procedure signal could not be detected (steps S6 and S1
2) If an error occurs, the process jumps to step S22, and the unexecuted flags of the pages not communicated are all set to "1" and the file is saved.

Here, on the Nth page, RTN rejection due to poor line
Is followed (step S13), the process of steps S14 and S15 is passed and the (N + 1) th page is transmitted. When other than the N-th page and was send successfully, P _all at step S17
= 1, and the total number of pages in the file mode is set to "1" in step S20.

To resend the file, the operator performs a key operation indicating his / her intention on the operation unit, and then inputs the reception number notified at the time of storage in the memory.

The control unit 1 searches the file management information table shown in FIG. 24 for a valid data bit = 1 and a reception number matching the key input number.

Then, file storage destination information is obtained from the management information, and transmission is executed again according to the flow of FIG. Here, the destination may be input again by the operator,
The destination at the time of first dialing may be stored.

In this transmission, since the unexecuted flag = 0 for the first page and the (N-1) th page, the process is successively passed on the basis of the next page storage location information in FIG. When the unexecuted flag = 1 is found, the page is transmitted. In step S8, the page No. = N obtained from the page information is added to the image as a header, so that the receiving side can easily arrange the received original. When this page is transmitted normally, P _ok = 1 in step S15, P _all = 01 in step S17, and the image is erased in step S19 according to the determination in step S18.

[Other embodiments]

Although the above description is for a single destination, it is also possible to manage error page information for each destination by broadcast transmission.

FIG. 4 is an example of a method for managing broadcast transmission. The destination bit map is assigned one bit per destination in the order of one-touch dial 01, 02, 03 ... speed dial * 00, * 01 ... ten-key dial. When a destination is specified, "1" is set to the corresponding bit. Is done. The ten-key storage area is an area for storing ten-key information that is keyed in each time. In this example, ten-key dialing can be specified for up to eight destinations. (They are managed for each file in the file management information in FIG. 2.) First, the area of the total number of pages in FIG. 22 and the area of the unexecuted flag in FIG. Just secure,
Use only the area of the specified destination.

Initialize the same as before at the time of accumulation, and set a one-touch key (0
If it is 5), the operation is performed according to the flow of FIG.

However, it is necessary to change the step S19 in FIG. 3 as shown in FIG.

In step S19-1, when all pages have been transmitted normally, the destination bit corresponding to the destination in the file management information is set to 0.

Then, in step S19-2, it is determined whether or not all the destination bit maps are zero.

If there is 1 bit in step S19-2, S19-3 is passed.

In step S19-3, if all the destination bit maps are 0, the image memory is erased. The destination bit is One Touch
Since the search is performed in the order of 01 bits and transmitted to the destination where 1 stands, the last bit T8 of the bit map is
Is completed, the broadcast transmission ends.

As a result, the file is retained without being erased until all destinations and all pages are transmitted normally.

As described above, by adding the function of managing the transmission memory by serial number, the function of managing the transmission result in page units, and the function of keeping the transmission memory in error without erasing it, Only pages that could not be sent due to an error by simply specifying them can be selected and resent.

Also, by adding a function for managing the transmission result in page units for each destination at the time of broadcast transmission, it is possible to automatically identify and retransmit an error destination and page by specifying a serial number.

This alleviates the need for the operator to search for and identify the original each time the document is resent.

Furthermore, the page number of the header of the transmission image at the time of retransmission is the same as the page number at the time of the first transmission, so that the reception side can easily arrange the reception image.

〔effect〕

As described above, according to the present invention, data having a communication error can be selected from a memory by inputting a reception code, read out, and retransmitted at an arbitrary time, thereby improving processing efficiency.
