BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus suitable for receiving documents larger than, for example, B4 size.

0002

[Prior Art] Conventionally, the size of paper set in a facsimile machine has been determined to be one or two types.
For example, it is A4 or B4 size. If the size of the received original matches these sizes, the original will be printed at its original size, but if the original is sent larger than these sizes, it will be automatically reduced and printed. be done.

0003

[Problem to be Solved by the Invention] For example, when receiving blueprints by facsimile where the dimensions of the drawing have important meaning, it may be desirable to print out the transmitted image data in its original size. . However, in such cases, if the size of the paper on the receiving facsimile machine is smaller than the size of the document on the sender's side, it will be automatically reduced, making it impossible to receive a document of the desired size. There's a problem. SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile device that can print out a document in its original size even when it receives a document larger than the size of the set paper.

EXAMPLES The present invention will be explained below with reference to illustrated examples. FIG. 1 shows the state of facsimile communication in this embodiment. In this example, the originating facsimile machine 20 is an A3
The facsimile machine 10 on the receiving side is configured to print out the received document on A4 size paper. In the state shown in the figure, the facsimile device 20 on the sending side is reading an A3-sized document B in the vertical direction, and the image data of this document B is divided into two by the facsimile device 10 on the receiving side. It is printed out on paper E and F.

FIG. 2 shows a document B on the sending side in this embodiment.
The relationship between the data and print paper E and F on the receiving side is shown. Original B on the sending side is A3 size, with a vertical length of 420 mm.
The horizontal length is 297mm. On the other hand, the print papers E and F on the receiving side are A4 size and have a vertical length of 2.
The length is 97mm, and the horizontal length is 210mm. That is, the document B is divided into two parts by a dividing line C extending horizontally through the center thereof. The print papers E and F corresponding to these parts correspond to the upper and lower half parts of the originating original B, respectively, and the vertical direction of the printing papers E and F corresponds to the horizontal direction of the originating original B. matches. That is, on the receiving side, the image data of document B is rotated by 90 degrees and output.

FIG. 3 shows a facsimile machine according to an embodiment of the present invention. A network control circuit (NCU) 11 is provided at the end of the facsimile apparatus and is connected to a communication line such as a telephone line 12. The modem 13 modulates and demodulates transmitted electrical signals, and is provided between the network control circuit 11 and the decoder 14. An image memory 15 is connected to the decoder 14, and received data is encoded and stored in the image memory 15. Image division rotation processing unit 1
6 is a circuit that divides the received image data and rotates it by 90 degrees as described later, and is a circuit that divides the received image data and rotates it by 90 degrees.
CPU). The image memory 17 is a memory that stores received image data in units of dots. The printer 18 is connected to the image division rotation processing section 16,
The image data that has been processed by the processing unit 16, which will be described later, is printed out.

FIGS. 4 and 5 are flowcharts showing the process for printing out the sent original on A4 size paper when the sent original is A3 size. 5 shows the processing for the upper half of the original B, and FIG. 5 shows the processing for the lower half of the transmitted original B, respectively.

In this process, a line counter, a dot counter, and a byte counter are used, and by controlling the values of these counters, the upper half and lower half of the document B are respectively read. Before explaining FIG.
Each counter will be explained with reference to . Note that FIG. 6 shows addresses of the image memory 17 (FIG. 3). Figure 6
corresponds to a state in which an A3 document is held vertically. In this figure, the image memory has data P0 to P296 arranged in the horizontal direction, and each of these data consists of 1 byte (8 bits). With these data P0 to P296, one strip-shaped portion extending in the horizontal direction is displayed. There are 210 such band-like portions in the upper half of the document. That is, each data P0 to P296 is vertically 1
The document is transmitted at a line density of 8 dots/mm in the horizontal direction and 1 dot/mm in the vertical direction. The line counter specifies a strip-shaped portion with a thickness of 1 mm extending in the horizontal direction, and the value of the line counter L1 at the uppermost portion in the figure is 0. The value of the line counter increases by one each time the line moves down. For each data P1 to P296, the dot counter
It specifies one bit out of 8 bits,
It is shown in octal notation. For example, as shown in FIG. 7, if only the most significant bit is 1 and the others are 0, it is 80H,
If only the second most significant bit is 1 and the others are 0, then 40
H, and if only the fifth bit from the higher order is 1 and the others are 0, it is 08H. Byte counter is data P0~P
The byte counter corresponding to the leftmost data in FIG. 6 is 0, and the byte counter corresponding to the rightmost data is 296.

Referring to FIG. 4, in step 51, the image data of the document D stored in the image memory 15 (FIG. 3) is decoded by the decoder 14 (FIG. 3), and expanded into the image memory 17 dot by dot. be done. Next, in step 52, the byte counter is set to 0, in step 53, 80H is placed in the dot counter, and in step 54, the line counter is set to 209. Therefore, the most significant bit D of the lowermost and leftmost data P0' in the upper half of the document
7 is identified. That is, the lower left point of the upper half of the document is specified.

At step 55, the 8-bit data G in the image memory 17 addressed, ie, specified, by each counter is read out and input to the X register. An example of the contents of this X register, that is, the 8-bit data G that has just been read, is shown in FIG. 8. In the document, black parts are represented by 1 and white parts are represented by 0. In step 56, the X register (FIG. 8) and the dot counter (FIG. 7) are ANDed. As a result, if the value of the bit set to 1 in the dot counter is 0, data 0 is transferred to the buffer of the printer 18 (FIG. 3) in step 57, and the value of the bit set to 1 in the dot counter is transferred to the buffer of the printer 18 (FIG. 3). is 1, data 1 is sent to the printer 18 (
The data is transferred to the buffer shown in Figure 3). Thus, the data of only the bits set to 1 in the dot counter are retrieved from the image memory 17 and transferred to the printer 18.

In step 59, the value of the line counter is decremented by one. As a result, a band-shaped portion located 1 mm above the previously specified portion is specified. When the value of this line counter is still 0 or more,
Returning to step 55, the same process as described above is repeated. The data is transferred to the printer 1 in step 57 or 58 until the line counter value goes from 209 to 0.
8, the buffer of the printer 18 stores the data of the line extending from bottom to top (in the direction of arrow I) for the upper half of the original (sign E). In step 61, this one line of data is output by the printer 18. In this way, dividing line C
The image data in the image memory 17 (FIG. 3) is read out by scanning in a perpendicular direction, and printed out line by line.

In step 62, the dot counter is rotated once to the right, causing the bit that is set to 1 to be moved down one position. For example, if the value of the dot counter has been 80H until now, it becomes 40H by the process of step 62 (see FIG. 7). Also, so far 0
If it is 1H, the value of the dot counter returns to 80H by the process of step 62. Next, in step 63, it is determined whether the most significant bit D7 of the dot counter has returned to 1, that is, whether it has returned to 80H. 80H
Steps 54 to 63 are repeated until the
If it returns to 80H, the byte counter is incremented by 1 in step 64. As a result, the data one position to the right is specified. This step 6
In the process of step 4, if the byte counter is smaller than 296, the process returns to step 53 and steps 53 to 64 are repeatedly executed. On the other hand, if the byte counter reaches 297 in step 64, the data P
296 has also been read and the printout of the upper half of the image data has been completed, so the process advances to step 72 (FIG. 5) to print out the lower half of the image data.

The process in FIG. 5 is basically the same as the process in FIG. 4, and the steps corresponding to the steps in FIG. 4 are numbered by adding 20 to the step number in FIG. For example, step 72 corresponds to step 52 in FIG. Note that in step 74 of FIG. 5, unlike step 54 of FIG. 4, the line counter is set to 410 in order to identify the lowest part of the document. Since the other steps are completely the same as those in FIG. 4, their explanation will be omitted.

As described above, in this embodiment, the received image data is divided into two, and each of the divided image data is divided into nine parts.
It is configured to be rotated by 0° and printed out. Therefore, even if the received image data is larger than the print paper, it can be printed out without being reduced. Note that in the processing of FIGS. 4 and 5, the image data is output in its original size, but it may be reduced at a desired ratio if necessary. Further, the number of divisions of image data may be three or more. moreover,
For example, a broken line or a mark may be drawn at the parting line C to facilitate joining a plurality of printed sheets to obtain the same original document. This is easily accomplished by slightly modifying the flowcharts of FIGS. 4 and 5.
