BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a function of printing data stored in an image memory, which is transmitted after a transmission original is stored in an image memory.

0002

[Prior art] Figure 5 shows, for example, MEL of Mitsubishi Electric Corporation.
This is a hardware block diagram for printing data stored in memory in a conventional facsimile machine shown in the FAS6700 series service manual. In the figure, 1 is a thermal head, 2 is an image sensor, and 3
, 4 is a selector, 5 and 6 are reduction circuits, 7 and 8 are line memories, 9 and 10 are code circuits, 11 is a decoding circuit, 12 is an image memory, 13 is a G3 communication control unit, and 14 is a data bus. .

Next, the operation will be described. In FIG. 3, the image data stored in the image memory 12 is first sent to the decoding circuit BE11 and decoded. The decoded image data is reduced as necessary by the reduction circuit F2IM15 and sent to the line memory LM17. The image data sent to the line memory LM17 is sent to the thermal head TH1 via the reduction circuit F2IM15 and selectors SEL4 and SEL3, where it is recorded and printed. At this time, the reduction circuit F2IM15 does not edit the image data. As described above, in this method, the image memory 12
The image data stored in the image data cannot be recorded individually by selecting only a specific page when a plurality of original pages are read.

[0004] In addition, in this method, once a recording error occurs, the printing process ends without knowing the page of the image data at the time of the error, so the user checks the recorded image and then prints from the page of the image data where the error occurred. When recording and printing is performed again, recording and printing starts from the first page, and the previously outputted recording images are also output again.

FIG. 6 shows a schematic flowchart of this operation. According to this flowchart, first, the decoding circuit BE,
The reduction circuit F2IM1 and the thermal head TH are activated to transfer data from the image memory 12 to the decoding circuit. Next, once the data transfer is complete, the image data is decoded, reduced, and printed using a thermal head.
When all the data in the image memory have been subjected to the above processes, the image data processing ends.

[0006]

[Problems to be Solved by the Invention] Since the conventional facsimile machine is configured as described above, the image memory 12
When multiple sheets of scanned original image data are stored in the , it is not possible to select a specific page and simply record and print only the specific page, and the scanned document image data of multiple sheets of one scan is always stored in one batch. In addition, if a recording error occurs, unnecessary pages must be recorded and printed again, causing problems such as unnecessary recording paper being ejected.

The present invention has been made to solve the above-mentioned problems, and it is possible to select and record only an arbitrary specified page from among the plurality of read original image data stored in the image memory 12. The object of the present invention is to obtain a facsimile device capable of printing, and further to leave only the accumulated image data after the page where a recording error occurs in the above-mentioned image memory 12 and record and print only the page after the error occurrence page again.

[0008]

[Means for Solving the Problems] A facsimile device according to the present invention is a facsimile device that executes transmission processing after storing image data of a read document in an image memory. an editing memory that stores only the image data of a specified specific page; a data transfer means that transfers only the user-specified specific image data in the image memory to the editing memory; and a data transfer means that reads the image data from the editing memory and performs data processing. The device is equipped with data reading means for providing data.

[0009]

[Operation] According to the present invention, the data transfer means first transfers the image data of the selected designated page from the image memory to the editing memory, and sends the image data on the editing memory all at once to the decoding circuit for decoding. After digitizing, record and print only the designated pages at any time. Further, in the editing memory, image data of pages that have been normally recorded and printed are sequentially erased page by page.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a thermal head, 2 is an image sensor, 3 and 4 are selectors, 5 and 6 are reduction circuits, 7,
8 is a line memory, 9 and 10 are encoding circuits, 11 is a decoding circuit, 12 is an image memory, 13 is a G3 communication control unit, 14 is a data bus, and 15 stores read original image data of a selected specific page. Edit memory 16 is a direct memory access controller DMAC.

Next, the operation will be explained. In FIG. 1, among the image data stored in the image memory 12, DM
The AC 16 transfers only the read original image data of the selected specific page to the editing memory 15. At this time, DMAC
It is assumed that setting data information regarding a specific page selected by the user is stored and managed in a part of the table area of the editing memory 15 in FIG. 1 in the format shown in FIGS. 4 and 5.

Next, the read original image data of the specific selected page stored in the editing memory 15 is sent to the decoding circuit BE11.
is sent to and decrypted. The decoded image data is F
2IM15 reduces the data as necessary and sends it to the line memory LM17. Line memory LM1
The image data sent to 7 is F2IM1 5, SEL
4. The image is sent to the thermal head TH1 via SEL3 and recorded and printed. Therefore, among the image data of the read original on the image memory 12, the image data of only a specific page selected by the user can be arbitrarily recorded and printed without directly affecting the image data stored on the image memory 12. be done.

FIGS. 7 and 8 show schematic flowcharts of this operation. First, FIG.
After that, the head address table of the information for each page in FIG. 4 is created in the format shown in FIG. 5. Next, after sequentially setting the data on the head address information table in FIG. 5 for the DMAC16,
Start C16. Image memory 12 by DMAC16
After completing the DMA data transfer of the read original image data of the selected specific page from to the editing memory 15, the editing memory 1
5 to the decoding circuit BE11 on a line-by-line basis, and thereafter, all the image data of the specific page on the editing memory 15 is recorded and printed by the thermal head TH1 via the reduction circuit F2IM15.

Furthermore, in the above embodiment, setting data information regarding a specific page selected by the user as shown in FIGS. 4 and 5 is stored in a part of the table area together with the corresponding specific page in the dedicated editing memory 15. Although the information is stored all at once, the setting data information regarding the specific page may be stored and managed in the conventional image memory 12, as shown in FIG. At this time, as shown in FIG. 4, an information table for the total number n of specified pages includes setting data information in which each start address and data length on the image memory 12a for a specific specified extraction page selected by the user is set as one set. From this information table, only the specific page on the image memory 12a is recorded and printed based on the setting data for each designated extraction page.

[0015]

As described above, according to the present invention, the editing memory for storing image data of a specific page specified by the user extracted from the image data of a plurality of scanned originals stored in a normal image memory can be used in a conventional facsimile machine. By adding it to the device, reading the image data from the editing memory and printing it, it is possible to extract only an arbitrary specific page from all the read original image data on the image memory and then record and print it.
