Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of linear variable magnification.

[0002]

2. Description of the Related Art In a conventional facsimile apparatus capable of linear scaling, scaling is performed on the assumption that the first received line information is recorded as the first one line of recorded information. It was It should be noted that the linear scaling refers to a process for scaling the main scanning direction and the sub-scanning direction of an image independently.

That is, the main scanning direction and sub-scanning direction in transmission correspond to the main scanning direction and sub-scanning direction in recording. More specifically, the received image information is in the same direction as it is. In the case where the recording is performed by, and the recording is performed by rotating the image by 90 degrees or by changing the vertical and horizontal directions, the linear scaling is not applied.

[0004]

For this reason, when the received image information is converted by 90 degrees and recorded, the received image information does not fit on the cut sheet and information is lost, or the received image information of one page is not recorded. There was a drawback that it was divided into multiple pages and recorded.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of performing proper linear scaling even when a received image is vertically / horizontally converted and recorded and preventing image loss and the like. And
