TECHNICAL FIELD OF THE INVENTION
The present invention relates to a double-sided printing facsimile apparatus having an image backup function.
[0002]
[Prior art]
Currently, information devices equipped with a double-sided printing function are increasing for resource saving. In order to save resources, users increasingly use backing paper that is already printed on one side. Under such circumstances, some conventional facsimile apparatuses have a double-sided printing function, and the user can use the backing paper.
[0003]
As a technical example similar to the present invention, there is a document reading and recording apparatus capable of recording in page order even when pages having different reading conditions are mixed (for example, see Patent Document 1). In addition, there is a facsimile apparatus that reliably records image data on a new sheet or on a back sheet (for example, see Patent Document 2).

[0005]
[Problems to be solved by the invention]
However, the two-sided printing and the use of the backing paper described above cannot be performed at the same time, and if the two-sided printing is performed from the paper supply tray where the backing paper is set, another new paper may overlap with the original printed side of the backing paper. Information is printed, so that the received information cannot be read. In particular, in a facsimile, the information from the other party is erased when the printing is completed, so it cannot be printed again just because it is printed on the backing paper.
[0006]
Further, in the above-mentioned prior art example, Patent Document 1 retains a stored image without erasing it, but the purpose is to insert image information with different reading conditions, and to mistakenly perform double-sided printing on the backing paper. It does not solve the case. [0013] of Patent Literature 1 states that "if a backing sheet (recording sheet on which single-side recording has been performed) is used as the recording sheet for the test recording, new recording paper will not be wasted." Not valid. In Patent Document 2, backing paper and blank paper are selected. However, since the inside and outside lines are distinguished and the mode on the transmission side is selected, and the target property does not have a function of printing on both sides, the case of double-sided printing is used. Is not valid.
[0007]
Therefore, when the use of the backing paper and the double-sided printing are performed simultaneously, the image information is backed up during the double-sided printing, the image information can be read and printed later, and the backed-up image information is not excessively accumulated. A double-sided printing facsimile apparatus capable of erasing and reducing the amount of information is desired.
[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0019]
FIG. 1 is a block diagram of a facsimile apparatus according to an embodiment of the present invention. The system control unit 1 performs a control process of each unit and a facsimile transmission control procedure. The system memory (DRAM) 2 is used when the system control unit executes a program, by recording necessary data and the like, and as a work area. The scanner 3 reads a document with a predetermined image. The plotter 4 prints images or list reports at a predetermined resolution. The read-only memory (ROM) 5 is an area for storing programs and various tables. The writable non-volatile memory (SRAM) 6 is linked with the image memory (SAF) 9 and stores parameters necessary for system control and registration data obtained by a user operation. The network control unit 7 connects to a public telephone line network and has an automatic calling function. The G3 FAX modem 8 realizes a group 3 facsimile modem function. The image memory (SAF) 9 stores a transmission image and a reception image as needed. The encoding / decoding unit 10 compresses a raw image into a predetermined code or decompresses an encoded image into an original raw image. The operation display unit 11 performs a communication operation, a registration operation, and the like, and includes various keys and a display.
[0020]
As the double-sided printing function of the multifunction peripheral, facsimile reception, printer, copy, report printing, and the like can be considered. The above-described facsimile apparatus shown in FIG. 1 relates to the relationship between the two-sided printing backing paper of facsimile reception, printer, copy, and report printing, which are main functions of the present invention.
[0021]
Further, the facsimile apparatus includes a back-side paper discharge machine that sequentially reads P1 and P2 while discharging paper, and a front-side paper discharge machine that sequentially reads paper from the last page to P1 while discharging paper. Now, the backside discharge machine will be described. Although the front-side discharge machine also has a different printing order on the front and back sides, the concept of dividing into a text part and an image part is the same.
[0022]
Next, the duplex printing mechanism of the facsimile machine will be described with reference to FIG. The double-sided printing mechanism includes a paper ejection sensor 13, a fixing roller 14, a photoconductor 15, a registration roller 16, a transfer roller 17, a branch sensor (integrated with a claw and a filler) 18, a conveyance roller 19, and a registration sensor 20. I have. The writing section is a system in which the recording paper is reversed after one-sided writing and the path is switched to return to the original path. The present invention is effective even in the case where the number of writing units is two, and the present invention is effective regardless of the writing speed.
[0023]
However, in the case of the back side discharge, first, P2 is printed as the first side, and then P1 is printed as the second side. Therefore, a page memory for two pages is secured for double-sided printing in accordance with the determination of page division, and the pages are developed in the page memory in the order of P1 and P2 and double-sided printing is performed from P2.
[0024]
Next, the operation at the time of facsimile reception will be described focusing on the data path. FIG. 2 shows a data path for direct reception. The system control unit 1 reads the program from the read-only memory 5 and controls the whole while using the system memory (DRAM) 2 and the writable nonvolatile memory 6. During reception, the network control unit 7 detects an incoming call, closes the line, and connects the call. Thereafter, the protocol is exchanged, the image information (compression) is converted into a digital signal by the G3 FAX modem 8, the compressed data is stored in the image memory (SAF) 9, and the encoding / decoding section 10 converts the image information (raw) into the image signal (raw). The data is decrypted and developed in the page memory (PM) on the system memory (DRAM) 2, and the data is sent to the plotter 4 and printed. The image data is stored in the image memory (SAF) 9 so that the plotter 4 may go down on the way to guarantee the image information.
[0025]
Next, a data path for memory reception will be described with reference to FIG. Until storage in the image memory (SAF) 9 is the same as in the case of direct reception described above, but the data path beyond the encoding / decoding unit 10 is not passed. The image information (raw) is not sent to the plotter 4. This is because printing is performed after receiving the memory. After the line is disconnected, the image memory (SAF) 9 is read out, decoded by the encoding / decoding unit 10 into image information (raw), developed in the page memory (PM) on the system memory 2, and sent to the plotter for printing.
[0026]
Next, the data path of the buffer copy will be described with reference to FIG. The image information read by the scanner 3 is developed in a page memory (PM) on a system memory (DRAM) 2 and the data is sent to a plotter 4 for printing.
[0027]
Next, the data path of the buffer copy will be described with reference to FIG. After the data is stored in the image memory (SAF) 9, the data path is the same as the memory reception data path described above. Image information (raw) read by the scanner 3 is compressed by the encoding / decoding unit 10 and stored in the image memory (SAF) 9. The stored image information (compressed) is read from the image memory (SAF) 9, decoded into image information (raw) by the encoding / decoding unit 10, and expanded in the page memory (PM) on the system memory (DRAM) 2. To the plotter 4 for printing.
[0028]
Next, a receiving method for duplex printing will be described. Normally, both direct reception and memory reception can perform double-sided printing. In the case of direct reception, since image data (SAF) 9 is stored in the background in the background, image information (compression) is simultaneously decoded and converted into image information (raw), and page information on system memory (DRAM) 2 is stored. PM). The MCF is returned to the other party when the first page is received, and is not printed here. When the second page is received, the MCF is returned to the other party, and when the image information (raw) for two pages is accumulated in the PM, printing is performed in the duplex printing mode. Thereafter, printing is not performed on the odd-numbered pages, but is performed in the double-sided printing mode when the even-numbered pages are received. If the last page is an odd page, printing is performed in the simplex printing mode. However, if the user wants to keep the printing surface constant, even pages are printed with blank pages, and after passing through the duplex mechanism, odd pages are printed. By doing so, the printing surface of the odd-numbered pages becomes constant, and even if recording paper with a logo is used on one side, they are arranged in order. If the last print page is an even page, printing is performed in the duplex printing mode.
[0029]
On the other hand, in the case of memory reception, printing is started after all image information is received and the line is disconnected. The image information (compression) of the odd-numbered page and the even-numbered page is read from the image memory (SAF) 9, decoded into image information (raw) by the encoding / decoding unit, and developed in the PM on the system memory (DRAM) 2. When the image information (raw) for two pages is accumulated in the PM, the plotter 4 performs printing in the duplex printing mode. If the last page is an odd page, printing is performed in the simplex printing mode.
[0030]
Next, a copy method for duplex printing will be described. Normally, duplex printing can be performed for both buffer copy and memory copy. In the case of the buffer copy, the read image information (raw) is developed as it is in the page memory (PM) on the system memory (DRAM) 2. It does not print when the first page is read. When the image information (raw) for two pages is accumulated in the PM when the second page is read, printing is performed in the duplex printing mode. Thereafter, similarly, printing is not performed on the odd-numbered pages, but is performed in the double-sided printing mode when the even-numbered pages are read. If the last page is an odd page, printing is performed in the simplex printing mode. However, if it is desired to keep the printing surface constant, the even pages are printed with blank pages, and the odd pages are printed later through the duplex mechanism. By doing so, the printing surface of the odd-numbered pages becomes constant, and even if recording paper with a logo is used on one side, they are arranged in order. If the last page is an even page, printing is performed in the duplex printing mode.
[0031]
Next, the operation of the facsimile apparatus according to the embodiment of the present invention will be described in detail with reference to FIGS. 6 to 10 showing the operation display unit 11 of the facsimile apparatus.
[0032]
First, a first embodiment will be described. Set two-sided printing as a machine in advance. As a setting method, the right arrow key is pressed after the display of FIG. 6A, and the setting key is pressed after the display of FIG. 6B. Also, ON / OFF of double-sided printing is set for each paper feed stage. The setting method is to press the right arrow key after the display of FIG. 7A and press the setting key after the display of FIG. 7B. Select duplex printing or single-sided printing. At this time, it is possible to add restrictions such as double-sided printing only by the other party or double-sided printing only at a certain paper feed stage. Here, only the case where all of the two-sided printing is set as a representative is described.
[0033]
Here, it is assumed that double-sided printing is ON at a certain paper feed stage, but back paper is present. In the conventional apparatus, when a certain job has been printed on both sides, the image information is deleted. However, in this assumption, the image information is printed on the already printed surface of the backing paper. In this case, there is a possibility that the image information cannot be read, which is very troublesome for the user.
[0034]
Therefore, a backup is made when double-sided printing is performed. In the case of this assumption, readable image information can be obtained by recalling the backed-up image information and performing one-sided printing again or replacing the recording paper with a blank sheet and printing on both sides again. Since the area to be backed up needs to record not only the backup but also the transmission image information, it is limited to a part of the entire memory area.
[0035]
Next, a second embodiment will be described. In the case of the first embodiment described above, there is a possibility that the image information area overflows by backing up all the image information during double-sided printing. Therefore, the second embodiment is improved so that only the received document is backed up. The reason is that the printer, copy, manual start report, and the like are jobs that are executed by the user's intention, but are received by the other party's intention and cannot be created again by the receiving side. In addition, since the system automatically outputs the report of automatic startup and erases the information, back it up and print it once again if necessary, or replace the recording paper with blank paper from the backing paper and retry it if necessary. By performing double-sided printing, readable image information can be obtained.
[0036]
Next, a third embodiment will be described. In the first and second embodiments described above, it is not necessary to make a backup when absolutely no backing paper is used in each paper feed stage. Therefore, the third embodiment provides a method for setting ON / OFF of the backup at the time of double-sided printing. As shown in FIG. 8, the user's operation is to press the right arrow key after the display of FIG. 8A, and press the setting key after the display of FIG. 8B. When the backup is turned off, the received document is not backed up and the image information capacity is not used, so that a limited memory can be efficiently used for the image information of the transmission reservation.
[0037]
Next, a fourth embodiment will be described. In the above-described first and second embodiments, the memory capacity is consumed unless the backed up information is erased. Thus, the fourth embodiment provides a method for erasing image information that has been normally printed by duplex printing. If the user wants to keep the image information as it is after the display of FIG. 9A, the user presses the confirmation button in FIG. 9B, and presses the delete button when the deletion is OK. The method is not limited as long as, for example, only the head of the image information is printed on the report, the image information to be deleted can be selected and the image can be deleted by a method similar to this. In this case, a message asking whether to delete the backup file is always displayed on the LCD or the like, and the user is prompted to delete the file.
[0038]
Next, a fifth embodiment will be described. In the above-described fourth embodiment, if the user manually deletes the image information, the capacity may be full. Therefore, in the fifth embodiment, the oldest image information recorded is automatically deleted. If the image information still does not fit in the backup image information area, a plurality of old image information are sequentially deleted.
[0039]
Next, a sixth embodiment will be described. In the sixth embodiment, in the fourth embodiment described above, if the user manually deletes the image information, the capacity may be full. In that case, the job for which duplex printing is specified returns an error. In the fourth embodiment, since the display in which the backup image information remains is displayed, it can be seen that the backup image information is deleted. When the information is automatically erased, there is a possibility that image information printed on the already recorded surface of the backing paper may be erased. In order to solve this problem, it is made impossible to delete automatically.
[0040]
