DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed-size original that can be obtained at a destination even when a fixed-size original is transmitted. The present invention relates to a fixed size transmission / reception facsimile apparatus capable of receiving a document as an original.

[0002]

2. Description of the Related Art When an original is transmitted by using a facsimile apparatus, the original is optically read by a transmission source facsimile apparatus to be digital data, and the digital data is transmitted to a transmission destination via a communication line. On the other hand, the facsimile machine of the transmission destination obtains the original by recording the received data on a sheet. At that time, usually, the facsimile machine of the transmission source also transmits data on the transmission source together with the document data. Therefore, when an original of a standard size (for example, A4 size or B4 size) is transmitted from the transmission source facsimile device to the transmission destination facsimile device, if the transmission destination facsimile device uses roll paper, The original was larger than the standard size.

[0003]

As described above, in the conventional facsimile apparatus, when roll paper is used for paper,
There is a drawback that the received document becomes larger than the standard size and protrudes from the file of the standard size, which is inconvenient to handle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of receiving a document of a fixed size regardless of transmission / reception.

[0005]

In order to achieve the above object, a facsimile apparatus according to the present invention reads and transmits a document every predetermined line, and converts the data of a predetermined line from the vicinity of the last line of the document to all white data. Sometimes, after transmitting a certain number of lines of all white data, the original transmitting unit transmits only data other than all white data without transmitting all white data, and receives an image signal transmitted for each predetermined line. When the image signal is near the last line of the original and the data of the predetermined line is all white data, the whole white data following the reception of the certain number of all white data is not received,
A document receiving unit that receives only data other than the all-white data.

[0006]

With this configuration, it is possible to ignore all white after the last line at the time of transmission.
A fixed size original can be obtained at the transmission destination. Also,
Even when a document larger than the standard size is received, a received document of a standard size can be obtained by ignoring all white data after the vicinity of the last line at the time of reception.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments.

FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention.

A facsimile apparatus shown in FIG. 1 includes a document transmitting unit 1 for outputting digital data as transmission data such that a receiver can receive a document of a fixed size even if the document is read and transmission source data is transmitted; A document receiving unit 2 that can receive a document larger than a standard size by adding transmission source data to the digital data as a standard size document
And a communication device 4 that connects the original transmitting unit 1 and the original receiving unit 2 to the telephone line 3 to transmit and receive data.

The document transmitting section 1 includes a scanner 11, a line counter 12, an all-white detecting section 13, a transmission control section 14, and an encoding section 15. When the data of the predetermined number of lines is all white data in the vicinity of the line, all the all white data is not transmitted, and after transmitting all the white data of a fixed number of lines (at least one line), the remaining all white data is not transmitted. ,
It is configured to transmit only data other than all white data. The scanner 11 reads an original optically and converts it into digital data. The output of the scanner 11 is connected to a line counter 12, and the output data is input to the line counter 12. Similarly,
The output of the scanner 11 is connected to the transmission control unit 14 via the all-white detection unit 13, and transmits the original data to the transmission control unit 14.
To supply. The line counter 12 is a scanner 11
The scanning line is counted, and the position of the document being scanned can be detected, and the transmission control unit 14 can read the count value. The transmission control unit 14 is formed of a computer, and by executing the flowchart of FIG. 2, forms data that can be received by a receiving facsimile machine at a fixed size. The transmission control unit 14 is provided with an all-white flag. The data formed by the transmission control unit 14 is input to the encoding unit 15. The encoding unit 15 encodes the data for transmission and sends it to the communication device 4.

In the communication device 4, the modem 41 is
The transmission data from 5 is used as data for the telephone line 3 and transmitted to the telephone line 3 by the network control unit (NCU) 42. On the other hand, in the communication device 4, the data received by the network control device 42 is converted into data for a facsimile device by the modem 41 and can be supplied to the document receiving unit 2.

The original receiving section 2 includes a decoding section 21, a line counter 22, an all-white detecting section 23, a receiving control section 24, and a printer 25, and receives an image signal sent every predetermined line. If the image signal is in the vicinity of the last line of the original and the data of a predetermined number of lines is all white data, after receiving a certain number of lines (at least one line) of all white data, it does not receive all white data. Receive only data other than data. The output of the decoding unit 21 is connected to a line counter 22, and the output data is input to the line counter 12. Similarly, the output of the decoding unit 21 is connected to the reception control unit 24 via the all-white detection circuit 23, and supplies the original data to the transmission control unit 14. The line counter 12 counts the number of decoded lines so that the position of the currently decoded original can be detected, and the count value can be read by the reception control unit 24. The reception control unit 24 is constituted by a computer, and operates by executing the flowchart of FIG. 3 so that the received document has a standard size. Further, the reception control unit 24 is provided with an all-white flag. The data formed by the reception control unit 24 is input to the printer 25. The printer 25 records the received data on a sheet.

The operation of the embodiment configured as described above will be described.

First, two modes of communication between facsimile apparatuses according to the present invention and communication between the facsimile apparatus of the present invention and another facsimile apparatus are conceivable. In either case, a document transmitting section 1 and a document receiving section 2 are provided. It is sufficient if either of them performs the operation of the present invention, but if both of them are provided, it is possible to transmit and receive a fixed-size original regardless of the transmission and reception with any facsimile machine.

<Transmission Operation> First, the transmission operation will be described. After the original is set and the necessary items for transmission are input, transmission starts. First, the transmission control unit 14 clears the all white flag (sets “0”) (step
(S201), the line counter 12 is cleared (set to 0) (step S202). Next, the transmission control unit 14 transmits the transmission source data such as the transmission source telephone number and the transmission source name stored in advance (step S203). Next, the transmission control unit 14 sets an offset value of, for example, +14 in the line counter 12 (step S12).
S204). As a result, a space for adding the source information to the document is secured. Thereafter, the scanner 11 reads the original for one line. The data for one line is transmitted to the encoding unit 15 by the transmission control unit 14, and is transmitted to the transmission destination via the communication device 4 and the telephone line 3 (step S205). When the transmission of the image data for one line is completed, the line counter 12 is incremented (LP = LP + 1), so that the transmission control unit 14 reads the count value of the line counter 12, and this reads the substantially final line portion of the predetermined standard document. (For example, 1
(100 counts) is determined (step
S206). When it is determined that the document is small (step S206), the process returns to the one-line transmission process (step S205) because the document is in the middle of the document. When it is determined that the document is large (step S206), it approaches the final line of the standard document. Therefore, one line of the scanner image signal is read (step S207), and the all-white detecting unit 13 detects whether the read one line is all-white. At this time, if the signal from the all-white detecting unit 13 is not all-white (step S208), the transmission control unit 14 sets the all-white flag to “1” (step S209), and transmits one line (step S209). S210). Then, the transmission control unit 14 determines whether one page has been completed (step S211), and if not completed, the process proceeds to the process of causing the all-white detection unit 13 to read one line of the scanner image signal (step S207). .

When the signal from the all-white detector 13 is all-white (step S208), the transmission controller 14
Checks the all-white flag, and if this is "0" (step S212), sets the all-white flag to "1" (step S213), and transmits the data (step S21).
0). Then, the transmission control unit 1 determines whether one page has been completed.
The determination is made in step 4 (step S211), and if not completed, the process proceeds to the process of causing the all-white detection unit 13 to read one line of the scanner image signal (step S207).

Further, when the signal from the all-white detector 13 is all-white (step S208), the transmission controller 1
4 checks the all-white flag, and if this is "1" (step S212), it is determined that the previous one line has been transmitted, and the data for that line is not transmitted, and one page is immediately completed. The process proceeds to a determination process (step S211).
As a result, the final line with a standard size (11 in the embodiment)
00), after sending one line of white,
Ignore white data until there is data other than white. As a result, data for a fixed size original can be sent to the destination.

<Reception Operation> Next, the reception operation will be described. When there is an incoming call, after performing the initial operation necessary for reception,
Start receiving. First, the reception control unit 24 clears the all white flag (sets “0”) (step S30).
1) The line counter 22 is cleared (set to 0) (step S302). Next, the reception control unit 24 receives the transmission source data transmitted from the transmission source (step S3).
03). Next, in the line counter 22, an offset value in a state of, for example, +14 is set by the reception control unit 24 (step S304). As a result, a space for recording the transmission source information is secured. Thereafter, the received data for one line is decoded by the decoding unit 21,
The data is received by the reception control unit 24 via the line counter 22 and the all-white detection unit 23 (step S205). When the reception of the image data for one line is completed, the line counter 22 is incremented (LC = LC + 1), so that the reception control unit 24 reads the count value of the line counter 22, and this reads the almost final line portion of the predetermined standard document. (For example, 1100 counts) (step S306). When it is determined that the document is small (step S306), the process returns to the one-line receiving process (step S305) because the document is in the middle of the document. However, when it is determined that the document is large (step S306), the final size of the standard document size is determined. Since this means that the last line has been approached, the all-white detecting unit 23 is operated to read one line of the scanner image signal by the all-white detecting unit 23 (step S307). At this time, the reception control unit 24 sets the all-white detection unit 2
If the signal from 3 is not all white (step S308), the all white flag is set to "0" (step S309), and one line is received (step S310). Then, the reception control unit 24 determines whether one page has been completed (step S31).
1) If the processing has not been completed, the scanner image signal is read for one line by the all-white detection unit 23 (step S3).
Go to 07).

When the signal from the all-white detector 23 is all-white (step S308), the reception controller 24
Checks the all-white flag, and if this is "0" (step S312), sets the all-white flag to "1" (step S213), and receives the data (step S31).
0). The reception control unit 2 determines whether one page has been completed.
The determination is made in step 4 (step S311), and if not completed, the process proceeds to the process of causing the all-white detection unit 23 to read one line of the scanner image signal (step S307).

Further, when the signal from the all white detector 23 is all white (step S308), the reception controller 2
4 checks the all-white flag. If this flag is "1" (step S312), it is determined that the previous one line has been received, and the data for that line has not been received. The process proceeds to a determination process (step S311).
As a result, the final line with a standard size (11 in the embodiment)
00), after receiving one line of white,
Ignore white data until there is data other than white. As a result, data for a fixed-size original can be received. In the processing during reception (steps S205 and S210), the printer 25 is driven by the transmission control unit 14.

There is no problem if the transmission operation and the reception operation according to the present invention are performed at the same time. However, it is preferable that the operation is switched according to the model of the other party and the operation according to the present invention is performed in either the transmission or the reception. Is also possible. Further, it is possible to provide a margin for binding to a file by setting the offset value of 14 counts to a larger count value.

[0022]

As described above, according to the present invention, an original of a fixed size can be obtained at the transmission destination by ignoring all white near the last line at the time of transmission, or all white data near the last line at the time of reception. By ignoring the above, a received document of a standard size can be obtained, and the handling of the document becomes convenient, and there is an effect that a part of the transmission information is not lost.
