〔Example〕

FIG. 1 is a system diagram showing one embodiment of a facsimile apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a main control unit for controlling the entire facsimile apparatus using a microprocessor, and 2 denotes a main control unit which is connected to the main control unit 1 so that the main control unit 1 controls transmission and reception of the facsimile apparatus. A line corresponding unit 3 for performing connection / disconnection processing is connected to the main control unit 1, a line memory for temporarily storing image information of one line from a page memory 9 described later, and 4 is connected to the main control unit 1. , A line memory 3 is a recording unit for printing image information, 5 is connected to the control unit 1, a reading unit for reading an original and generating image information at the time of transmission, 9 is connected to the main control unit 1, 1
A page memory 10 for storing image information of pages is a boundary line generator connected to the main control unit 1 and generating a boundary line (for example, a dotted line, a dashed line, etc.) 8a (see FIG. 8).

Next, the operation at the time of reception will be described. The image information received from the partner device is sent to the main control unit 1 through the line corresponding unit 2. The main controller 1 manages the page memory 9 using a page memory management table (hereinafter, simply referred to as “management table”) shown in FIG. The operation of the main controller 1 when two short originals that can be printed on one cut sheet are received will be described with reference to FIGS. 2 (a) to 2 (c). At the start of reception, “1” is stored in the page number storage section P of the management table, an address counter (not shown) indicating an address for transferring image information to the page memory 9 is cleared, and the value is set to 1 in the management table. It is stored at the page start address A1 (steps 100 and 101). Until image information for one line is received, the image information is transferred to the page memory, and the address counter of the page memory 9 is increased by that amount (steps 102 to 1).
04). If the page memory is not full and the page reception has not ended, the contents of the address counter are stored on the one-page end address B1 (step 107). The above processing (steps 102 to 104, 107) is continued until the page memory 9 is full or one page has been received. In the case of the present embodiment, one page reception ends. When the reception of one page is completed, it is determined whether the communication has been completed (step
106, 108), if the communication is not completed, "1" is added to the page number storage section P of the management table to become "2", and one page stored in the page memory 9 is stored in the one page end address B1. The end address of the received image information is entered. Next, it is determined whether or not there is an area of the page memory 9 in which the next page is to be entered. When the area is full, the boundary pattern generated by the boundary generator 10 is transferred to the page memory 9,
The address counter is incremented by that amount.
(Steps 112 and 113). The value of the address counter is stored in the two-page start address A2 of the management table. Thereafter, the above processing (steps 102 to 104, 107) is continued until the page memory 9 becomes full or one page is received. When the reception of one page is completed, the end address of the image information of the second page stored in the page memory 9 is stored in the second page end address B2 of the management table. In the present embodiment, the N-page print subroutine is called because the communication has been completed at the same time as the reception of two pages (steps 105, 106 to 108, 114).

The operation of the main control unit 1 by the N page print subroutine will be described with reference to FIG. This subroutine operates based on the management table shown in FIG. First, M = “1” is stored in a page number storage unit different from the number storage unit P (step 115), and is sequentially transferred to the line memory 3 from the one page start address A1 to the one page end address B1 on the page memory 9. Then, the recording unit 4 prints on the cut sheet (step 116). Next, "1" is stored in another page number storage unit.
Is added to "2" (step 117), and it is determined whether or not N ≧ M. (Step 118). Page memory 9
Since there is image information of the next page at the top, the process returns to step 116, and the start address of page 2 and the end address of page 2
The data is sequentially transferred to the line memory 3 up to B2, and the recording unit 4 prints on a cut sheet. Also, at this time, it is assumed that the next transferred to the last of the page memory 9 returns to the first.
The contents of the page number storage section P of the management table are determined, and when there is no more image information to be printed on the page memory 9, cut sheet discharge processing is performed (steps 118 and 119). Therefore, two short documents that can be printed on one cut sheet are printed together on one cut sheet.

When the above process (steps 102 to 105) is continued and the page memory 9 becomes full, the image information is printed on the cut sheet until the page in the page memory 9 is completed. The value of the start address of the currently received page is stored in the start address A1 of one page of the management table, and the value of the page number storage section P of the management table is set to “1” (steps 120 to 123). The processing (steps 102 to 105) is continued. Therefore, all the image information previously stored in the page memory 9 is printed on the cut sheet and discharged. The currently received image information is subsequently stored in the page memory 9.

In the above embodiment, the line memory 3 is provided. However, the line memory 3 may be included in the recording unit 4. Further, the boundary line generator 10 may store the boundary line pattern in a ROM or a RAM, and include the boundary line pattern in the main control unit 1.

〔The invention's effect〕

As described above, according to the present invention, a page memory for storing image information for one page of recording paper is provided, the empty area is determined, and based on the determination result of the empty area, the image information of the next original is stored in the page memory. Until it is determined that storage is not possible, the received plural originals are sequentially stored in the page memory with the respective image information and the discriminating information inserted after the image information of each of the originals. If it is determined that the image information of the next original cannot be stored in the page memory on the basis of the image information, the image information stored in the page memory is recorded on one sheet of recording paper, so that it is possible to print on one page of cut paper. Short pages of a plurality of pages can be collectively printed on one page of cut paper, so that there is an effect that a facsimile apparatus in which waste of cut paper is eliminated and boundaries between the cut sheets are clear is obtained.
