Abstract

PURPOSE:To print out a received original in a real size by printing out received original data while eliminating sender data when the length of the received original data is longer than the length of recording paper by the sender data. CONSTITUTION:A facsimile signal from a telephone line 6 is demodulated by a MODEM 5 and stored in one-line buffer 10 of a work memory 9 one by one line each, and when a page end signal is detected, the number of lines forming one page is counted by a counter 11. A count value (a) and a printable maximum line number (b) set in advance in a program memory 3 are compared, and in the case of a>b, a control section 2 compares a difference between the data (a) and (b) with a line number (c) of a sender data area. In the case of a-b<=c, a print section 8 is controlled to record data except a c-line area of a print buffer 7. In the case of a-b>c, b-lines are printed on 1st recording paper and remaining lines are printed on a 2nd paper sheet. Thus, the printing in real size and a deformed drawing is eliminated and the recording paper is utilized effectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art At present, generally used facsimile machines use roll paper as recording paper. In such an apparatus, the received original can be printed on one continuous recording sheet, no matter how long the received original for one page in the sub-scanning direction is. Specifically, in the case of transmitting an A4 size document, for example, in a normal facsimile apparatus, the transmission source data is added to the head of the transmission data read from the A4 document and transmitted, so that the receiving side receives it. The size of the original in the sub-scanning direction is larger than the A4 size by the destination data, but in the device using the roll paper, the length to which the destination data is added is regarded as one page length and one continuous sheet is fed. Print on the recording paper. Therefore,
The size of one page of recording paper printed on the receiving side can be larger than the size of the transmitted original.

On the other hand, in recent years, a facsimile machine using a laser beam printer or the like as a recording means employs not a roll paper but a so-called cut paper which is cut in advance to a predetermined size called A4 size or B5 size.

For this reason, for example, when the transmitted original is A4 size and the recording paper on the receiving side is also A4 size cut sheet, the length of the received original is increased by the destination data, so that one page is received. The original cannot be printed on one sheet of recording paper.

[0005]

As a method for solving this problem, for example, as described in Japanese Patent Publication No. 4-12665, a method of reducing and printing a received document in the sub-scanning direction can be considered.

However, it sometimes happens that the printed received original is made smaller than the original transmitted original. For example, when a design drawing is transmitted, there is a problem that a transmission original on the transmission side and a received original have a difference in size, and as described in the above publication, when only the sub-scanning direction is reduced, the original is There is also the problem that the figure inside will be deformed (eg circle → ellipse).

As another solution, it is possible to divide one page of the received document into two recording sheets and print it. However, if the received document portion to be printed on the second recording sheet is In the case where it corresponds to the last margin portion of the transmission document, there is a problem that the recording paper is wasted as a result.

[0008]

The present invention has been made to solve the above-mentioned problems, and is characterized by means for storing at least one page of received document data and one page stored in the storage means. Means for counting the length of the received original document, means for comparing the length a of one page of the received original document obtained by the counting means with the length b of the recording paper on which this original document is to be printed, As a result of the comparison means, when a> b, means for controlling so as to selectively print only the data excluding the area of a predetermined length from the top line of one page of the received document is provided.

[0009]

According to this structure, when the length of the received original for one page becomes longer than the length of one sheet of recording paper, data for a predetermined length from the beginning of the received original is not recorded.

1 is a block diagram showing an embodiment of a facsimile machine (1) according to the present invention. In the figure, (2) is a control section composed of, for example, a microcomputer, and (3) is, for example, a semiconductor ROM (read only). The control section (2) controls each section described below based on the control program in the program memory (3). The control unit (2) and the other units are connected by a bus (4).

(5) is a modem, which demodulates the modulated facsimile signal sent through the telephone line (6), while modulating the facsimile signal sent to the telephone line (6). Then send it out.

Reference numeral (7) is a print buffer composed of, for example, a semiconductor RAM (random access memory), and at least one page of received manuscript data formed by compounding the facsimile signal demodulated by the modem (5) is stored in the memory. Is stored.

Reference numeral (8) is a printing section composed of, for example, a laser beam printer, and the printing section is the printing buffer (7).
The received original data inside is printed on the recording paper consisting of cut paper.

(9) is a work memory composed of a semiconductor RAM, and the memory has a 1-line buffer (10) and a reception line counter (1) necessary for the control operation of the control section (2).
Values such as 1) are stored.

FIG. 2 is a flow chart showing the control operation of the control unit (2) based on the control program stored in the program memory (3), and the operation of this embodiment will be described below based on this chart. .

First, in step S1, telephone line (6)
Prior to the start of reception of the facsimile signal sent via the control unit (2), the control unit (2) clears the print buffer (7) and resets the content of the counter (11) to "0". In the subsequent step S2, the 1-line buffer (10) is cleared, and the process proceeds to step S3.

In step S3, the control unit (2) starts reception, sends a facsimile signal for one line which is sent via the telephone line (6) and demodulated by the modem (5) to the work memory (9). The data is stored in the 1-line buffer (10). The facsimile signal for one line has the configuration shown in FIG. That is,
MH or M for the original for one line read by the sender
There are a configuration (a) in which only one EOL signal is added after the R-coded encoded data and a configuration (b) in which six EOL signals are added after the encoded data.
As shown in the structure of (a), the EOL signal is 1 after the encoded data.
In the case of only one, this EOL signal simply indicates the end of one line, and when there are six consecutive EOL signals after the encoded data as in the structure of (b), the end of one line and the end of the page are indicated. Show. In the following, six consecutive EOL signals will be referred to as RTC signals.

Therefore, the control unit (2) determines the break of the facsimile signal for one line by the EOL or RTC signal.

When the facsimile signal for one line is fetched into the one-line buffer (10) in step S3, the control unit (2) continues to the counter (1 in step S4).
The value of 1) is incremented by "1". Then S
In 5 steps, the received document data obtained by decoding the encoded data in the 1-line buffer (10) is stored in the print buffer (7) as print data.

Next, in step S6, the control unit (2) determines whether or not the signal following the encoded data in the 1-line buffer (10) is an RTC signal.

When it is determined that the signal is not the RTC signal in this determination, the control unit (2) returns the processing to step S2,
The same processing as described above is repeated for the facsimile signal for one line sent next.

The above steps S2 to S6 are repeated until the RTC signal appears in the facsimile signal for one line received in step S3. When the RTC signal appears, the control unit (2) detects it in step S6. Then, the process proceeds to step S7.

At the time of proceeding to step S7, the received original data corresponding to the facsimile signal received so far is stored in the print buffer (7) for one page, and the number of lines constituting the data for one page is Counter (1
1) It is a value.

In step S7, the counter (11) is
The value is stored again as a variable a in the work memory (9),
In the subsequent step S8, the variable a is compared with the first constant b preset in the program memory (3). The first constant b indicates the maximum number of lines that can be printed on the recording paper on which the received document data is printed.

When it is determined in step S8 that "a≤b", the control section (2) advances the process to step S9. In step S9, the print unit (8) is controlled to read all the received document data stored in the print buffer (7) and record it on one recording sheet.

On the other hand, if it is determined in step S8 that "a>b", the control section (2) advances the processing to step S10. In step S10, the difference between the variable a and the first constant b, and the second value preset in the program memory (3).
The comparison with the constant c is performed. The second constant c is, for example, a value based on the number of lines in the area estimated to be the transmission source data on the upper end side in the received document data.

Accordingly, in step S10, "ab≤c".
If it is determined that the control line (2) is c from the first line in the received document data consisting of a lines in the print buffer (7).
Up to the line is regarded as the source data as shown in Fig. 4, and S
In the 11th step, the printing unit (8) is controlled so as to limit the data of the received original data stored in the print buffer (7) except for the c lines from the uppermost line to one recording sheet.

When it is determined in step S10 that "ab>c", the control unit (2) stores a in the print buffer (7).
From the last line in the received document data consisting of lines (a
It is considered that the line-b) has not only the blank space but also the data to be printed as shown in FIG. 4, and the process proceeds to step S12.

In step S12, only b lines from the uppermost line of the received originals stored in the print buffer (7) are printed on the first recording sheet as shown in FIG.
The printing unit (8) is controlled so that the remaining lines after the (b + 1) th line are printed on the second recording sheet. That is, S1
In step 2, the received document data in the print buffer (7) is divided into two recording sheets and printed.

At this time, when all the data after the (b + 1) line to be printed on the second recording paper is blank, it is possible to control not to print on the second recording paper. .

When the processing of S9, S11 or S12 is completed, the control section (2) advances the processing to step S13. In step S13, whether or not there is a subsequent page is confirmed based on the control signal (MPS, EOM or EOP) sent from the facsimile machine of the other party via the telephone line (6). The process is returned to step S1 and the above-described operation is performed again. On the other hand, when there is no subsequent page, the process is terminated.

In this embodiment, steps S8 and S10 are performed.
Although the step is determined by the number of lines, it may be determined by the length data corresponding to this number of lines.

[0033]

According to the present invention, when the length of the received original data becomes longer than the recording paper length by adding the source data, the source data in the received original data is excluded. Since only the print sheet is printed, even if the received recording paper is a cut sheet, all the necessary received originals can be printed in actual size.
