Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus which employs an electrophotographic recording system in which recording data such as received data is printed out on a normal recording paper in page units.

[0002]

2. Description of the Related Art Conventionally, in a facsimile machine, a roll-shaped thermal recording paper or a normal recording cut into a fixed size such as A4 or letter size has been used as a recording paper used for printout of recording data such as received data. Paper is used.

In a facsimile machine using a roll-shaped thermal recording paper, the thermal recording is carried out by a cutter which is operated in response to each original length detection signal from the transmitting side after printing the recording data on the thermal recording paper by the printer. The paper is cut, and the thermal recording paper is used in an amount corresponding to the capacity of the recorded data.

For example, in a facsimile apparatus adopting an electrophotographic recording system using a standard recording paper of A4 size or the like, one page of recording data is stored in a page memory, and the recording data stored in this page memory is electronically stored. A photo recording type printer prints out one page at a time on ordinary recording paper. Even if the recording data for one page is considerably smaller than the capacity that can be recorded on one sheet of normal recording paper,
One piece of plain recording paper is used. On the other hand, if the length of paper for which the print data for one page is longer than the standard size A4 is used as the transmission document, the amount of data that can be recorded on one sheet of normal recording paper is larger. In the case of (1), the recording data that cannot be recorded on one normal recording paper is recorded on the second normal recording paper, and the recording data for one page is divided into two by using two normal recording papers.

[0005]

In a conventional facsimile machine adopting the electrophotographic recording system, a standard plain recording paper such as A4 is used for recording the recording data.
If the recording data for one page is considerably smaller than the capacity that can be recorded on one sheet of ordinary recording paper, there is only a printed portion on the leading edge side of the ordinary recording paper, and there is a margin in most of the rest. Occurs, and normal recording paper is wasted.

On the other hand, in the case of received data using a long original paper, the recording data for one page is larger than the capacity that can be recorded on one normal recording paper, and one A4 normal recording. The recording data that cannot be recorded on the paper is recorded on the second ordinary recording paper, two ordinary recording papers are used, and the recording data for one page is divided into two. Also in this case, if there is a small amount of recording data to be recorded on the second ordinary recording paper, a large amount of blank space is generated and the ordinary recording paper is wasted.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to effectively use paper by using ordinary recording paper wound in a roll shape in a facsimile apparatus adopting an electrophotographic recording system. And

[0008]

According to the present invention, a page memory for storing recording data such as received data, and one page of recording data stored in the page memory are printed out on a normal recording paper page by page. A printer unit of an electrophotographic recording system, a paper feeding unit that feeds a roll of plain recording paper toward the printer unit while detecting the pull-out feed amount, and a plain recording paper fed by the paper feeding unit. The cutter means for cutting the sheet along the width direction, the capacity determining means for determining the capacity of the recording data for one page stored in the page memory, and the recording data for one page determined by the capacity determining means. A paper length control means for feeding the normal recording paper by the paper feeding means by a length corresponding to the capacity is provided.

[0009]

According to the present invention, at the time of printing output, the capacity of the recording data for one page stored in the page memory is judged, and the ordinary recording paper wound in a roll shape by the length corresponding to the capacity of the recording data. Is sent to the printer unit and cut by cutter means, and the print data is printed on the cut normal recording paper by the printer unit and output.

Can be selectively set by the keyboard 36.

Next, the operation of this embodiment will be described.

First, the case where the variable paper length mode is set and the received data is printed out at the time of facsimile reception will be described with reference to FIG.

When the receiving process is started, the received recording data is written in the page memory area of the RAM 24 (step).

The print data for the first page of the transmission original is stored in the RAM.
When the writing to the page memory area of 24 is completed (step), the capacity of the recording data for one page written in the page memory area is judged by the function of the capacity judging means of the CPU 21, and the paper length control means of the CPU 21 is also judged. With the function of, the required paper length is obtained corresponding to the capacity of the recording data for one page (step).

Then, the stepping motor 7 of the paper feeding means 5 is driven to feed the plain recording paper P, and the feed amount (length) of the plain recording paper P is detected from the number of steps of the stepping motor 7 (step). .. The initial position of the front end of the ordinary recording paper P delivered by the paper delivery means 5 is the position cut by the cutter means 8 at the time of paper setting or the previous printing. The front end of the ordinary recording paper P sent out is
It is sent to the portion of the reversing roller 3 through the cutter means 8.

When the feeding amount of the plain recording paper P corresponding to the step number of the stepping motor 7 reaches the obtained paper length (step), the paper feeding means 5 is stopped and the feeding of the plain recording paper P is stopped. Then, the cutter means 8 is operated and the plain recording paper P is cut along the width direction (step).

Then, as shown in FIG. 4, for example, when the print amount of the received record data is small, when a standard plain recording paper P1 such as A4 having a length shown by a two-dot chain line in the figure is used, Although a large margin portion is generated, since the normal recording paper P is used after being cut to a paper length corresponding to the capacity of the recording data, no blank portion is generated and the normal recording paper P can be saved. On the contrary, when a long transmission original is used, even if the printing amount of the received recording data for one page is large, the original length for one page is detected and the normal recording paper P is lengthened for one page and cut. By doing so, it is possible to print on one sheet.

After the second page of the transmission original, a roll-shaped ordinary recording paper is pulled out and cut into a paper length corresponding to the capacity of the recording data for each page, as in the case of the first page of the transmission original. After that, it may be conveyed to the printer unit 9 and printed out.

As described above, the roll-shaped ordinary recording paper P is cut to a length corresponding to the capacity of one page of the recording data written in the page memory area, and the recording data is printed on the ordinary recording paper P. Therefore, the ordinary recording paper P can be saved and effectively used.

In the variable paper length mode as described above, not only reception but also recording data such as communication report and copy can be printed out.

The paper length variable mode and the paper length constant mode can be selectively set by the keyboard 36.

Further, the printer unit 9 is not limited to the laser system, but an electrophotographic recording system such as an LED system is used.
