Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a recording control method, and particularly to a facsimile apparatus that records image information on a recording medium such as cut paper.

(Prior Art) Conventionally, in facsimile machines, roll-shaped thermal paper has often been used as a recording medium for recording visible images as hard copies. Generally, the size and resolution of document images that a facsimile device receives from a communication partner's facsimile device vary. For example, the paper size of the manuscript is, for example, l5O-
There are various sizes such as A4 standard and J15-84 standard. In conventional facsimile machines that use roll paper, original images of various sizes are recorded in a reduced size according to the size of the recording paper. The length of the original image in the sub-scanning direction also varies. For example, some manuscripts are of standard length, while others are longer than the standard length. Roll recording paper type facsimile machines are not limited in the length of recording paper in the sub-scanning direction, and can therefore accommodate any document length.

There is also diversity in resolution between the original image signal and the recording section of the facsimile machine. In some conventional facsimile machines, for example, when the resolution of the original image signal is lower than the resolution of the recording section of the apparatus, a plurality of scanning lines are printed with the same image information to adjust the difference in resolution. for example,
There was one in which a received original image of 8 dots)/1111 x 3.85 lines/open was scanned with the same image information for two sub-scanning lines and recorded at 8 dots)/am x 7.7 lines/i11.

(Problems to be Solved by the Invention) However, facsimile machines that have a recording section such as a laser printer or an LED printer and that record on plain paper cut to a predetermined size have problems with facsimile machines that use roll-type recording paper. There was the following problem.

Generally, these recording units record within a recordable area that is slightly narrower than the size of the recording paper, for example, approximately 5+ seconds inside from the periphery of the recording paper.

Therefore, when a received original is recorded in its original size, the upper, lower, left and right edges cannot be reproduced.

Additionally, since standard-sized recording paper is used, received manuscripts that are longer than the standard length cannot be recorded at their original size on a single sheet of recording paper.A method is used to record such manuscripts over multiple pages. , the part of the received document that cannot be accommodated on one page is recorded on the second page of recording paper, and this page becomes almost blank. This is because the document itself is longer than the standard length. Even if the document is of standard length, slipping occurs when the sending device reads the document, or if display of sender information or the like is added outside the page of the standard length document.

Furthermore, the recording section of conventional devices was configured to record at a constant resolution in both the main scanning direction and the sub-scanning direction.
Received originals are recorded at their original resolution. Therefore, the received image may be recorded in a reduced size and not reproduced as the original image.

Finally, in a facsimile machine that has communication functions in both the G3 communication mode and the G4 communication mode, the signal of the received document has a reception resolution in millimeters and inches, respectively. Therefore, when a received image with a resolution of millimeters received in G3 communication mode is recorded in a device that has a plain paper recording section with a resolution of inches, for example, some playback distortion such as a circle being recorded as an ellipse may occur. Occasionally this occurred. Conventionally, in such a printer, for example, 8 dots)/ff1m x 7.7 lines/
■ Receive images with a resolution of 200 dots/inch x 2
It was assumed that the image had a resolution of 0.00 dots/inch and was recorded without converting the resolution. To correct this reproduction distortion, a conversion device is required to convert the size and resolution of the received image.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile machine that can overcome the drawbacks of the prior art and can appropriately record a visible image on a cut sheet used in a recording section of a receiving device, regardless of the size and resolution of the original image. shall be.

The recording unit 6 records this on recording paper.

As you will see, the image data thus recorded on the recording paper by the recording unit 6 is used in the recording unit 6 of this apparatus in this embodiment based on the size and resolution of the original sent from the destination facsimile machine. The image is converted using an appropriate recording conversion rate selected based on compatibility with the size of the recording paper being used. Therefore, an appropriate image is recorded on a recording medium suitable for the recording section, regardless of the size and resolution of the original image.

In addition, in operations where reduced recording is not allowed, the recording conversion rate table 32a for full size recording is used, and in that case, when using the recording conversion rate of G3 mode (g1□19g1□1) or later, G3 communication and G4 communication This is the resolution conversion in the case of .
