Abstract

PURPOSE:To omit a procedure signal between pages by sending information corresponding to two pages as consecutive picture information when the operator makes transmission operation to apply main scanning of an original of size B5 in the lengthwise direction. CONSTITUTION:When the operator sets information by 4 pages to apply main scanning to an original of size B5 in the lengthwise direction and makes transmission operation, whether or not a page is a final page is discriminated at the point of time of the end of subscanning by one page and the information corresponding to 2 pages is sent successively as one page. Since the picture signals corresponding to 2 pages are sent at once continuously, the processing time required for a procedure signal between pages is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to facsimile equipment, and more particularly to a transmitter capable of transmitting 84 format data. BACKGROUND ART Conventionally, facsimile machines with 84-size transmission capability have been known to transmit one page in a B5-size document when the operator sets the document in such a way that the main scan is performed on the long side of the document, which is equivalent to a B5-size document.
When transmitting multiple pages, the sub-scanning length is 179 mm, which is equivalent to the short side length of the format.
J) for each page, and MCF (CCITT
-' MessageC as indicated in the T30 Recommendation
The time "L1" in FIG. 4, which corresponds to onfirsation Signal J (a signal indicating that the other receiver has definitely finished receiving one page), exists between all pages. On the other hand, if the other party's receiver uses 84-size cut paper, there are recorded images on the first half of the B4-size received paper, but
The remaining half will be blank space. As an example, Figure 5 shows the case where four pages are sent consecutively. S is 4 on the sending side
R2 indicates a 4-page recorded image on the receiving side, with a blank space in the remaining half of each page. Problems to be Solved by the Invention The above-mentioned conventional facsimile machine that complies with the CCITT-T4 and T30 recommendations and has the ability to transmit B4-size originals has a problem in that the operator is able to When a document is set to be scanned and a transmission operation is performed, "L1" in FIG. 4 appears between all pages.
This method has the disadvantage that wasted time is generated due to mere confirmation that has nothing to do with the transmission of image information corresponding to ``.''. Furthermore, tl=
It is around 2.5 seconds. On the other hand, if the other party's receiver uses 84 size cut paper as recording paper,
In addition to the wasted time of L+J, there is a drawback that half of the receiving recording paper becomes a blank space. The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new facsimile transmitter that can overcome the above-mentioned drawbacks inherent in the prior art. Means for Solving the Problems In order to achieve the above object, a facsimile transmitter according to the present invention is a facsimile device that complies with CCITT-T30 and T4 recommendations and is capable of transmitting originals in any size of B or A. In the transmission part, there is a means for detecting the sub-scanning length, and an operator sets the original so that the long side of the original corresponding to a lower size following any size of B or A is scanned in the main scan, and performs a transmission operation. and a means for controlling the transmission of the two pages of the lower size as one page of the arbitrary size when the lower size is transmitted. That is, in the case of 84 size and B5 size as a specific example, the present invention can be applied when the main scanning length of the transmitted document is 256 am, that is, 84 mm and B5 size.
A means for detecting the sub-scanning length when it is determined that the long side length of 5 size or the short side length of 84 size, and a means for detecting the sub-scan length when it is determined that the short side length of 85 size is equivalent to the short side length of 85 size. B4 size 1
It has a means for transmitting continuous image information for pages. Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the transmitting side of a facsimile apparatus according to the present invention. Referring to FIG. 1, reference numeral 1 denotes a reading system, which performs detection of the presence/absence of a transmitted original, sub-scanning control and main scanning control (image information reading control) of the transmitted original. Reference numeral 2 indicates an image signal compression section, 3 a buffer memory for temporarily storing compressed image information, 4 a modulation section, 5 a network control section, and 6 a main control section. on the other hand,
7 is binary image information obtained by main scanning the original;
Reference numeral 8 indicates compressed image information, 9 indicates an output signal of the buffer memory, 10 indicates modulated image information, and 11 indicates a signal sent to the line. In addition, l2 is the control of each part of each element 1 to 5,
Since everything is controlled by the main control unit 6, signal lines for exchanging control information between them are shown. The present invention is realized by the control method of the main control section shown in 6 of FIG. 1, and this control method will be explained with reference to the flowchart of FIG. In order to realize the present invention, in FIG. 1, the presence/absence of a document is detected using the signal 13, the sub-scanning length is detected based on how many main scanning lines are compressed using the signal 14, and the sub-scanning length is detected using the signal 15. It is necessary to instruct the modulator to send a next page continuation procedure signal (MPS) or a final page end procedure signal (EOP). Figure 2 is a control flowchart showing one embodiment of the present invention. be. Referring to FIG. 2, after the start of the transmission operation, a parameter a, which determines whether or not to continue transmitting two pages as one page, is set to Tl. After that, after determining the main scanning length J of the original to be sent, the process enters judgment block 2l and determines whether 1 r ''265 + a + s (equivalent to the long side of 85 size, or equivalent to the short side of B4 size). 11・
265+u+> is determined, and if this is the case, the process proceeds to decision block 22 in which it is determined whether or not it is the final page at the end of sub-scanning for one page. Here, if there is a next page instead of the final page, the sub-scanning length 12 for the previous page is determined, and then the process goes to judgment block 24, and it is determined whether 12≦179±α■ That is, it is determined whether the length is equal to or less than the length of the short side of the BS size. If so, the process proceeds to decision block 25. The judgment block 25 determines that when two pages are sequentially transmitted as one page, a=1 for the preceding one of the two pages, but a=1 for the succeeding page.
2, the process moves to processing block 26, terminates the page, and sends the next page continuation procedure signal (14Ps). On the other hand, in the case of the preceding page <<a=1>>,
Change the parameter to a=2 and return to the beginning of the control flow. Note that the value of α of the judgment block 24 is normally within 3 mm. Furthermore, if it is determined in judgment block 22 or 23 that the page is the last page, the process univocally moves to processing block 27, sends out a final page end procedure signal (EOP), and ends the communication sequence.

FIG. 3 shows the facsimile procedure when the operator sets four pages of a B5-sized document so as to main-scan the long side of the document and performs a transmission operation using the facsimile transmitter according to the present invention. S indicates the sending side, R indicates the receiving side, and CH

N indicates a line release signal. According to the facsimile transmitter according to the present invention, since image signals equivalent to two pages are continuously transmitted at once, compared to the conventional method shown in FIG. 4, the image signals correspond to the procedure signals between pages. Time t1 is L, X2
Considerably less.

R1 in FIG. 5 shows a recorded image when transmitted from the transmitter according to the present invention.

In this embodiment explained above, B4 size and 85 size are described, but 85 size and 86 size, or A3 size and A4 size are described.
It is clear that the present invention is similarly applicable to A4 size, A5 size, etc.

Effects of the Invention As explained above, according to the present invention, when the operator performs a transmission operation to main scan the long side direction of an 85-size original, two pages worth of image information can be sent as continuous image information. By transmitting the information, the procedure signals between pages can be omitted, and, for example, when four pages of B5 size are continuously transmitted, the effect can be reduced by about 5 seconds. Furthermore, if the receiver uses 84-size cut paper as recording paper, the image information for four pages of 85-size paper can be transferred to B4 without creating any margins, as shown in R1 in Figure 5.
The effect of making it possible to record with only two pages can also be obtained.
