Description

[Detailed Description of the Invention] This invention is capable of pasting a color original onto a scanner drum at a predetermined accurate angle, and at the same time, accurately arranging necessary images in the color 1 original at a predetermined position within the format. The present invention relates to a method and apparatus for doing so.

Conventionally, color scanners have been known that have a so-called Kiri Shihino function, that is, a full-wave four-plate function, which performs both color separation and final layout at the same time.

In order to load the original into a scanner that processes color separation and full-hage collection simultaneously, the scanner must be placed at a predetermined angle with respect to the baseline of the scanner's gap drum according to the final layout. It is necessary to have the following.

The reason for this is that when the original 2 is attached to the original drum 1 straight with respect to the thread line 3 of the original drum as shown in FIG. The image 6 exposed on the film 5 also becomes a straight image with respect to the base line 7 of the exposure drum 4.

Therefore, in order to fully utilize the function of this scanner to process color separation and layout at the same time, the second
As shown in the figure, if an image 8 diagonal to the base line 7 of the exposure drum 4 is required, when the document 2 is attached to the document drum 1, the image 8 is diagonally to the base line 3 of the gap drum I. Must have 4 strands. This is because when such a scanner body scans a document and then exposes the film on the exposure drum 4, the scanner itself has a function that rotates the scanned image at an arbitrary angle relative to the document before exposing it. Even if the angle rotation is performed by the computer that processes the information for the page collection, problems such as an increase in the capacity of the computer itself and an increase in processing time will occur, so it is not possible in terms of cost and time. This is because it is also disadvantageous.

Furthermore, the above-mentioned edit] 4 with a color scanner with functionality!
