Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for pasting a color original onto a scanner drum at a predetermined accurate angle, and at the same time accurately arranging necessary patterns in the color original at a predetermined position within the format. METHODS AND APPARATUS.

Conventionally, color scanners are 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 such color separation and full-page collection simultaneously, the document must be placed at a predetermined angle with respect to the baseline of the scanner's document drum according to the final layout. It is necessary to have the following.

To explain the reason for this, when the document 2 is attached to the document drum 1 immediately relative to the base line 3 of the document drum as shown in FIG. 1, the film 5 attached to the exposure drum 4 after being scanned is
The image 6 exposed to light also becomes a straight image with respect to the base line 7 of the exposure drum 4.

Therefore, in order to fully utilize the functions of this scanner for simultaneously processing color separation and layout, an image 8 oblique to the base line 7 of the exposure drum 4 is required, as shown in FIG. In this case, when the original 2 is attached to the original drum 1, it must be attached obliquely to the base line 3 of the original drum 1. This is because the scanner itself has a function that rotates the scanned image at an arbitrary angle with respect to the document before exposing it when exposing the film on the exposure drum 4 after the scanner body has scanned the document. Even if the angle rotation is performed by the computer that processes the information for the page compilation, 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 would be disadvantageous.

Furthermore, when editing with a color scanner that has the above-mentioned editing function, if there is an error in the placement position of the format, and the positional relationship of the images in the color document is edited to match the format, the images will be missing. There are cases. In that case, use a magnification device to project the color manuscript onto the format (or block copy), correct the position or magnification, rewrite the projected image correctly, etc. to find the correct positional relationship, and then use the editing device or drawing device to determine the correct positional relationship. There was a problem with having to re-enter data using a digitizer.

This invention was made in view of the above circumstances, and allows a color document to be accurately and easily pasted onto a color scanner drum at an angle according to the format, and furthermore, it is possible to mount a color document on a color scanner drum at an angle according to the format, and also to avoid errors in the placement position of the format in the pre-processing process. To provide a method and a device capable of accurately positioning a necessary picture in a color manuscript at a predetermined position according to its appearance in a later editing process even when there is a difference in color.

That is, the color original is set along a certain reference line on the projection means of a projection device that includes a digitizer board for placing the format, and a projection means for projecting the color original onto the board; The color original is projected onto the digitizer board while adjusting the magnification, so that the picture image of the color original and the corresponding image in the format match in angle and size; position indicating means arranged on the digitizer board; reads an arbitrary point in the picture image as a coordinate position from an arbitrary origin in the format; then, while keeping the angular relationship with the format as it is, move the color document parallel to the fixed reference line. The image is then moved and pasted onto the surface of the scanner drum, which is set up as a scanner drum; later, in the editing system, the coordinate position read above and a corresponding point in the picture image in the color original pasted on the scanner drum are determined. The present invention provides a method for positioning a document for a color scanner drum, characterized in that the documents are collated and matched.

Furthermore, the present invention provides a projection device that includes a document rack for setting color originals along a certain reference line, a projection lens, and a digitizer board for setting the appearance along a certain reference line in sequence. ; a collar which is pivotally supported on a shaft provided close to the digitizer board, has an original holding piece attached to its tip, moves in parallel along the shaft, and holds the color original through the original holding piece; a rotating arm that is moved to the peripheral surface of the scanner drum; a support that supports the color scanner drum so that the axis or reference line of the color scanner drum is parallel to the reference line of the digitizer board or the reference line of the document rack; The present invention provides a document positioning device for a color scanner drum, characterized by comprising:.

A color original adhering piece 27 is provided on the other side opposite to this. Note that the ruler 20 can be moved to any position within a plane parallel to the board 15 while maintaining a predetermined angle by fixing the screw 24.

A rotary arm 29 is provided on the side of the board 15, the base end of which is pivotally supported on a shaft 28 provided parallel to the reference line of the document rack 14, and movable along the shaft 28. . A document holding piece 30 is fixed to the tip of the rotary arm 29 for holding a color document 12 and transferring it to the surface of a color scanner drum, which will be described later. Further, when the original holding piece 30 is in the lower position (that is, the position where the color original 12 is received from the arm mechanism 19) as shown in FIG.
A shaft 31 that supports the rear surface of the shaft 28 is provided substantially parallel to the shaft 28. Note that this arm 29 is expandable and retractable to match the diameter of the drum.

Slightly diagonally above the rotary arm 29, the color scanner drum is mounted so that its axis is parallel to the reference line of the document rack 14, and the peripheral surface of this drum is in contact with the upper surface of the document holding piece 30. A scanner drum support frame 32 is provided. Therefore, when the color scanner drum 33 is attached to the support frame 32 and the rotating arm 29 rotates and stands up about the shaft 28 as shown in FIG. The upper portion comes into contact with the circumferential surface of the drum. or,
This drum support 32 rotatably holds the drum 33. Note that the drum support frame 32 is not limited to the illustrated example, and can be attached to the board 15 at any other arbitrary position.

Next, an explanation will be given of the operation when the color scanner drum document positioning device is used to adhere the color document 12 to the color scanner drum circumferential surface at a predetermined angle according to the appearance.

First, the color original 12 is properly fixed upside down on the upper surface of the transparent glass plate 35 with tape or the like, and then another transparent glass plate 34 is placed on top of it, and then turned left and right and placed on the original shelf 1. Set to . In other words, if the color original 12 is arranged as an upright image on the digitizer board 15, it is set in an inverted image state. In this case, the transparent glass plate 35
is set so that one side thereof is completely in contact with the reference line of the document rack 14, for example, the innermost straight portion 13, so that one side thereof remains parallel to this reference line.

Next, the form 25 is attached to the ruler 20 using the form attachment pin 26 so that the registration mark 36 marked thereon is parallel to the side surface of the ruler 20. Next, project the color original 12 onto the format 25, adjust the magnification and adjust the angle of the ruler 20 to match the projection to the layout of the format 25, and then use the screw 24 to connect the ruler 20 and the second arm 22. Fix the angle between
