Abstract

PURPOSE:To enable exact patching of an original to the angle conforming to a format by adjusting the original fixed to a freely rotatably provided transparent original supporting plate to a specified angle with a reference line, projecting original onto a format attaching table and moving parallel the resulted image to a drum supported in parallel with the reference line by a rotating arm. CONSTITUTION:A color original ''a'' is fixed in a positive image facing forward on an original supporting plate 20 and a transparent plate 22 is superposed thereon and is set to an original frame 14. On the other hand, a format 25 with the top side down is fixed atop a format attaching table 15 in such a position where the register marks 34 of the format 25 parallel with the horizontal line of grid-like lines 24 and thereafter the original ''a'' is projected onto the format attaching table. The magnification of a projecting lens 9 is matched and at the same time the angle of the plate 20 is adjusted to make both images coincident with each other. An original rotating plate 12 is then taken out of the frame 14 and one side thereof is brought into tight contact with a backing plate 23 for the original rotating plate in parallel therewith. The plate 22 is removed and the color original ''a'' is transferred and fixed at the same angle to the bottom surface of an original holding table 30 by a rotating arm 29.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for applying a color document to a color scanner drum at a predetermined precise angle. Conventionally, color scanners are known that have a so-called editing function, that is, a full-page collection function, which performs color separation and layout at the time of final finishing. In order to load a document into a scanner that processes color separation and full-page collection at the same time, it is necessary to place the document in a predetermined position relative to the baseline of the scanner's document drum according to the final layout. It is necessary to have a certain angle. The reason for this is that when the original s2 is mounted on the original drum 1 straight with respect to the base line 3 of the original drum as shown in FIG. The image 6 exposed on the exposed film 5 also becomes an image that is straight with respect to the base line 7 of the exposure drum 4. 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 diagonal with respect to the base line 7 of the exposure drum 4 is required, when loading the document 2 on the document drum 1, the document 2 must be mounted diagonally with respect to the base line 3 of the document drum 1. There must be. 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 computer that processes the information for the page compilation performs angular rotation, problems such as an increase in the capacity of the computer itself and an increase in processing time will occur, so it will be costly and time consuming. This is because it is disadvantageous. This invention has been made in view of the above circumstances, and it is an object of the present invention to provide a document pasting device for a color scanner drum that can accurately and easily paste a color document onto a color scanner drum at the desired angle. purpose. That is, the present invention provides an original rotating plate that includes a transparent plate and a transparent original support plate that is rotatably provided within a plane on the transparent plate; a light source; and a document rotating plate that is set at a constant angle.
