If the recording paper cassette with the selected size is not loaded in this case, the recording paper cassette of the required size is displayed on a display section 10 and a buzzer 9 is energized to inform it to the operator that the replacement of the recording paper cassette is required. Thus, the waste of the recording paper is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile machine that uses recording paper of a standard size such as A3 size or A4 size.

(Prior Art) Conventionally, there are facsimile machines that record images on standard size records such as A3, 84, and A4, but these types of facsimile machines have a recording width (Δ3 Edition, 84th edition.

Recording paper that is compatible with A4 size, etc.) must be used.

Therefore, for example, in a facsimile machine set to the recording width of A3 size, if the Q of the received image signal, that is, the R of the image to be recorded is small, a lot of blank space will be created, and the recording paper will be wasted. A problem has occurred.

Therefore, a method has been considered in which information indicating the recording size is inserted into the width of the communication control procedure and a recording paper of a size suitable for the R of the image signal is selected, but this method is not compatible with the commonly used G3 machine. There is a problem that communication becomes impossible and versatility is lost.

An object of the present invention is to provide a versatile facsimile machine that can eliminate waste of recording paper.

[Structure of the Invention] (Means for Solving the Problems) The present invention selects an optimal size of recording paper according to the amount of image signals stored in a page memory that stores decoded image signals in page units. The above object is achieved by providing a recording paper selection means for recording.

(Function) In the communication control procedure, for example, the recording width of A3 size is set, but the number of strokes stored in the page memory is less than that of A3 size, and for example, when the width of the image is that of A4 size, the recording width of A4 size is set. Recording paper is selected.

Therefore, it is difficult to eliminate waste of recording paper, and
Since no recording paper →noise information is inserted during the communication control procedure, communication with general G3 aircraft is also possible.

Embodiment FIG. 1 is an overall block diagram showing an embodiment of the present invention, which includes a network control section 2 connected to a subscriber line 1, a demodulation section 3, a code memory 4, a demodulation section 5, and a page. Memory 6, printer interface 7, printer 8, buzzer 9, display section 10.
A page memory control unit 11 (111) is installed in the network control unit 2.
is connected.

In this configuration, the image signal received from the subscriber line 1 is demodulated by the demodulator 3 via the network controller 2. The demodulated image signal is stored in the code memory 4, then restored to an image signal corresponding to the original image transferred to the demodulation section 5, and stored in the page memory 6 in units of pages. page memory 6
The image signal is transferred to the print interface 7 and converted into a print signal compatible with the recording method of the printer 8. That is, if the printer 8 is a rask scan type printer, the image signal read from the page memory 6 is converted into a print signal for each line in the main scanning direction. The print signal is then input to the printer 8 and reproduced as an image on the recording paper 13.

Here, the page memory control unit 11 detects cloudiness in the image signal stored in the page memory 6 before recording the image, and when the Q of the image signal is less than 0 set in the communication control procedure, the n Select the optimal size recording paper cassette.

At this time, if the paper cassette of the selected size is not installed, the display unit 10 displays the paper cassette of the required size, and the buzzer 9 sounds, requiring the operator to replace the paper cassette. Notify that it is coming.

FIG. 3 shows the automatic recording paper selection system of the page memory control unit 11.
l(l) This is a flow chart showing the outline of 9 works. First, the recording width (A
3.84. An address value corresponding to any A4 size is set in the line pit address counter 111 for the first time (Sl). Next, the decoded image signals are sequentially input to the page memory 6 and stored (S2). When the input of image signals for one page is completed, the contents of the line address counter 110 (the number of sub-scanning lines for one page) are transferred to the control circuit 110.
12.

For example, for page memory 6, A3.84. When an A4 size image signal is stored, the storage state of the page memory 6 is as shown by diagonal lines in FIGS. 4A to 4C. Therefore, for an image signal of an A4 size sheet having a vertical size of 297 mm, if the scanning line pitch in the sub-scanning direction is 8 lines/mm, the total number of scanning lines is 2376.

When an image signal of size A41N is stored in the page memory 6, the value of the line address counter 110 is r237.
6J, which is read into the control circuit 112.

Once the control 611 circuit 112 has read the 1-value of the line address counter 110, it checks whether the current value is greater than or equal to a specified value (S5), and if it is greater than or equal to the specified value, it is Select a recording paper cassette (86), and if it is less than the specified value, select a recording paper cassette that vibrates in the sub-scanning direction (S7).

For example, when the recording width of A3 size is set in the communication control procedure, the total number of lines of the image signal stored in the page memory 6 is constant, as shown in FIG. If there are many, select an A3 size recording paper cassette. However, as shown in FIG. 5(b), if the number of lines for each machine is less than the specified value, A4 size recording paper is selected. At this time, A
The 4th edition recording paper is usually inserted in the longitudinal direction, so
The image corresponding to the image signal stored in the page memory 6 is 9
It is rotated by 0° and recorded.

This also applies to other sizes, such as A3°S4.
Regarding the size combinations of A/1 version, A3 version (vertical),
A3 version (horizontal), 84 version (vertical), 84 version (horizontal), A4 version (
You can select from a total of six types of usage formats: U), A4 version (vL), and A4 version (vL).

Next, if the recording paper cassette corresponding to →noise corresponding to the received signals is selected, it is checked whether or not this recording paper cassette is actually installed in the printer 8 (88).
If it is not 8th place, sound buzzer 9 (810)
, and further displays the size of the required recording paper cassette on the display unit 10 (511), and requests the operator to replace the recording paper cassette. In S3, the image signals received until the recording paper cassette is replaced are stored in the disk memory 113. Further, the size of the recording paper cassette can be easily recognized by detecting a protrusion or magnetic material indicating the size on a part of the cassette.

Therefore, when the recording paper cassette is replaced, the control circuit 11
2, the printer 8 is informed of the recording paper size via the printer interface 7 , and then the image signals stored in the disk memory 113 are sequentially read out page by page, and sent to the printer 8 via the page memory 6 and the printer interface 7 . to be transferred and recorded.

In this way, by selecting the optimal recording paper size according to the amount of image signals stored in the page memory 6, waste of recording paper can be eliminated.

Furthermore, since information on the recording paper size is not inserted into the communication control procedure, communication with general G3 machines can be performed without any problems.

In the embodiment, it is assumed that the printer 8 has a printer structure that can accommodate only one type of recording paper cassette.
If the structure is such that other types of recording paper cassettes can be installed at the same time, there is no need to use the buzzer 9 or the display unit 10 to issue an instruction to replace the recording paper cassette.

[Effects of the Invention] As explained above, this Komei allows recording of images by selecting the optimal size of recording paper according to the 0 of both signals stored in the page memory, thereby reducing the waste of recording paper. It is possible to eliminate this and reduce operating costs.
