Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for applying a color original onto a color scanner drum at a predetermined precise angle.

Conventionally, color scanners have been known that have a so-called editing function, that is, a full-page collection function, which performs color separation and final layout at the same time. In order to load a document into a scanner that processes color separations and full-page collections at the same time, the document must be predetermined in relation to the baseline of the scanner's document drum according to its final layout. It is necessary to have a certain angle.

The reason for this is that when the document 2t-11A Tachibana drum is attached to the document drum 1 straight with respect to the base line 3 as shown in FIG. image 6 exposed to film 5
The image is also straight with respect to the base line 7 of the g-source drum 40.

Therefore, in order to make full use of this scanner's ability to process color separation and layout at the same time, the second
As shown in the figure, if an image 8 that is oblique to the base line 7 of the exposure drum 4 is required, when the original 2 is mounted on the original drum 1, the original 2 must be mounted diagonally to the base line 3 of the original drum 1. υ must be added. This is because when the main body of the scanner scans a document and then exposes the film on the exposure drum 4, it has a function that rotates the scanned image at an arbitrary angle relative to the document and then exposes the film. In some cases, the scanner itself has this, but even if the computer that processes the information for the Peno collection performs angular rotation, the capacity of the computer itself will increase,
This is because problems such as an increase in processing time occur, which is disadvantageous in terms of cost and time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a document pasting device R for a color scanner drum, which can accurately and easily paste a color document on a color Φ yarner drum at an angle according to its appearance. With the goal.

That is, the present invention includes a projection plate having a reference line gold film, a projection lens provided below the projection plate, and a presentation fixing plate provided below the projection lens and movable in a plane parallel to the projection plate. , ``a projection device comprising an adjustment mechanism for adjusting the distance between the projection lens and the display fixing plate; and a light source for illuminating the upper surface of the display fixing plate; a color scanner drum support device that supports the color scanner drum so that its axis is parallel to the reference line of the projection plate; a shaft provided parallel to the reference line of the projection plate; and one end of the shaft; a rotary arm that is pivotally supported, has an original holding plate for holding a color original at the other end, and is provided so as to be movable along the shaft between the projection plate and the peripheral surface of the color scanner drum. A document pasting device for a color scanner drum is provided.

The present invention will be described below with reference to illustrated embodiments.
