Abstract

PURPOSE:To reduce a useless space on which original information is not recorded to reception paper by comparing the size of reception paper with that of an original when the reception paper is cut paper and combining plural pages of original information when the former is larger than twice the latter and sending the result. CONSTITUTION:An original size detection section 1 detects an original size when it reads an original and stores the read data in a storage memory, and a reception paper size detection section 2 detects the size of reception paper set to an opposite equipment by means of a protocol with the opposite equipment. Then a size comparison section 3 compares the original size detected by the original size detection section 1 with the reception paper size detected by the reception paper size detection section 2 and when the size twice the former is larger than the latter, a one-page transmission section is started and the information by one original page is sent to the opposite equipment. Thus waste of the recording paper is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile recording paper saving method, and more particularly to a facsimile recording paper saving method that eliminates waste of recording paper.

(Prior Art) Some conventional facsimile machines use standard paper (cut paper) as recording paper for received information. C
A normal facsimile machine that complies with the CITT recommendations is designed to be able to set A4 size or B4 size paper.

When receiving faxes on standard paper, it is important to ensure that the received information can be neatly finished when bound and distributed or stored, that high-quality paper can be used, and that the paper will not discolor over time. There are various advantages.

(Problem to be Solved by the Invention) Now, as shown in FIG. 5(a), a plurality of documents, for example A5 size, are sent from the sending facsimile machine in the horizontal direction (in the direction of the arrow a shown in the figure). ) to the reading unit, read it, and transmit it. It is assumed that an A4 size cut sheet is set in the facsimile machine on the receiving side, and the transmission information is received using the cut sheet. Then, as shown in FIG. 6(b), the received document information is recorded in half the area (hatched area) of the cut sheet, and the second half is blank, and multiple sheets are received. It turns out.

In a facsimile machine in which a cut sheet is set as a received sheet in this way, if the size of the original information sent from the sending side and the size of the set cut sheet do not match, the size of the original information may be is smaller than that of the cut paper, there is a problem in that a large amount of recording paper is wasted.

The object of the present invention is to eliminate problem G;1 of the conventional device,
To provide a recording paper saving method for facsimile capable of preventing waste of recording paper as much as possible even if the size of original information sent from a sending side and the size of the set cut paper do not match. It is in.

(Means and Effects for Solving the Problems) In order to achieve the above object, the present invention provides a document size detection unit that detects the size of a transmitted document, and a received paper size detector that detects the size of a received paper based on a protocol. a detection unit, a size comparison unit that compares the original size and the received paper size, and a one-page transmission unit that transmits one page of the original when the size of the received paper is smaller than twice the original according to the comparison; When the size of the received paper is twice or more that of the original, the present invention is characterized in that it includes a combined page transmitter that combines and transmits a plurality of pages of the original.

The document size detection section detects the size of the document when reading the document and storing the document in the storage memory. The received paper size detection section detects the size of the received paper set in the other party's machine according to a protocol with the other party's machine. The size comparison unit compares the original size detected by the original size detection unit and the received paper size detected by the received paper size detection unit, and when the former is twice larger than the latter, the one page transmission unit It is activated and information for one page of the original is sent to the other party's machine. On the other hand, when twice the former is less than or equal to the latter, the combined page transmitter is activated. The combined page transmitting unit combines the plurality of pages of the document information and transmits the combined page to the partner machine.

As a result, waste of received paper can be reduced.

(Example) The present invention will be described in detail below with reference to the drawings.

First, the principle of the present invention will be explained with reference to FIG. A facsimile machine on the sending side is provided with a document size detecting section 1 for detecting the size of the document to be sent, and a receiving paper size detecting section 2 for detecting the size of the received paper possessed by the facsimile machine on the receiving side. It is being The received paper size detection section 2 detects the received paper size in a protocol performed prior to transmission and reception of document information between the sending and receiving facsimile machines.

The size comparison unit 3 compares the original size X detected by the original size detection unit 1 and the received paper size Y detected by the received paper size detection unit 2. Then, when twice the document size X is thicker than the received paper size Y (2X>Y), the one-page transmitter 4 that transmits one page of document information is activated.

On the other hand, when twice the document size X is smaller than or equal to the received paper size Y (2X≦Y), the combined page transmitter 5 that combines and transmits a plurality of pages of document information is activated. Note that the selection of whether or not to use the function of the combined page transmitter 5 can be made by the combined page instruction unit 6 provided on the panel of the facsimile machine.

Therefore, according to the present invention, for example, when the size of the received paper is A4 and the original size is half of that size, A5, the combined page transmitter 5 combines the two pages of the original. Since the A4 version of the received paper will be sent with
Two pages of manuscript information for the 5th edition are recorded, eliminating waste of received paper.

Next, the present invention will be explained more specifically.

FIG. 2 is a system block diagram showing the general node configuration of the transmitting section of the facsimile machine.

The transmitted original is read by the reading section 11, converted into an electrical signal, and sent to the information compression section 12.

The information compression unit 12 compresses the document information using the most efficient compression method and stores it in the storage memory 13. When all of the document information to be transmitted is stored in the storage memory 13, the system control unit 16 starts the transmission operation.

The storage memory 13 based on instructions from the system control unit
The document information read out from the original information is recompressed by the information compression section 12 into a format suitable for the receiving facsimile machine, and is transmitted via the modulation section 14 and the communication control section 15.

In the present invention, the system unit 16 is provided with the functions described in the above principle, and one embodiment of the functions will be described with reference to FIG. 3.

When transmitting document information using storage memory, the document is read before calling the other party's machine. At this time,
The size (width and length) of the document is detected (step Sl
). As a result of this detection, the width (W) of the document is determined to be the same size as the short width (210 mm) of A4 size paper (i.e., W
= A4) and the length (L) is l mm (i.e. L-
1).

Next, twice the length of the document l ma+ and the length of A4 size l A4 (297o+m) are compared (step S2), and when 2R>lA4 (step S2 is negative)
In this case, the process proceeds to step S3, where it is determined that the size p of the document is A4, and the document is sent page by page as usual (step S4). Here, if Z>lA4, the document information can also be reduced by 2'/f times and transmitted so that l<=fA4.

On the other hand, when the judgment in step S2 is affirmative, that is, 2
When it is determined that 9<lA4, the size D of the document is changed to A4.
It is determined that it is the 5th edition (horizontal) (step S5).

Next, the receiving side facsimile is called (step 8.6), and if the connection with the other party is successful (
Step S7 is affirmative), communication based on the protocol is started. System control unit 16 of the sending facsimile machine
is the NSF sent from the receiving facsimile machine.
(non-standard function) (see FIG. 4) to detect the size of the received paper (steps S8, S9).

If the size of the received paper is A5 (horizontal), proceed to step SIO, display A5 transmission using NSS (non-standard function settings) (see Figure 4), and send page by page normally as an A5 original (step SIO).・Whelk 511).

On the other hand, when it is determined that the size of the received paper is not A5 (horizontal) (step S9 is negative), A4 transmission is displayed according to the N5SC non-standard function setting (step 512).
. Next, it is determined from the panel of the facsimile machine whether or not the operator has given an instruction to combine pages (step 513). If the page combination instruction has not been given, the process advances to step S4 and normal transmission is performed. At this time, the A5 manuscript information is
The information will be recorded on four sizes of received paper.

When the instruction to combine the pages is given (Ste knob S1
3 is affirmative), the process advances to step S14.

In step 514, a certain register! 0 to lA4(2
97ma+) is entered, then manuscript information (image information) 1
Transmission for the pages is performed (step 515). next,
It is determined whether or not there is manuscript information for the next page (step 516), and if there is (step S16 is affirmative),
The calculated value of C1O-1) is set in the register IO (step 517). Next, a comparison is made between the value set in the register 20, that is, the remaining space of the received paper, and the length 2 of the next page (step 818), and if the former is larger (step 818 is affirmative). , the process returns to step S15 and the document information for the next page is transmitted. As a result, two pages of document information are recorded on the received paper. On the other hand, when the former is smaller (step 818 is negative), an MPS (multi-page signal) is transmitted to request an update of the received paper (step 51).
9).

When the step S16 is negative, an EOP (end of procedure) is sent (step 520), and when an MCF (message confirmation) is received (step S21 is affirmative), the DCN
(a line disconnection command) is sent (step 522), and the line is restored (step 523).

As is clear from the above description, according to the present embodiment, if a page combination instruction is given, and the size of the sent document is A5 (horizontal) and the size of the received paper is A4,
Two pages of document information are recorded on each received sheet, eliminating waste of received sheets.

Although the above embodiment has been described with reference to the case where the received paper is A4 size, the present invention is not limited thereto, and it is clear that the present invention can be applied even when the received paper is 84th size.

FIG. 4 is an explanatory diagram of the protocol. Since this protocol is well known, its explanation will be omitted.

(Effects of the Invention) As described above, according to the present invention, when the received paper is a cut paper, the sizes of the received paper and the original are compared, and the former is the same as the latter.
If the number is larger than twice, multiple pages of the document information are combined and transmitted, which has the great effect of reducing the wasted space on the received paper where the document information is not recorded.

Furthermore, according to the present invention, the receiving side can be a normal facsimile machine, and there is no need to add any special equipment.
It also has the effect of being easy to implement.
