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 final layout at the same time. In order to load a document into a scanner that simultaneously processes color separations and full-page collections, the document must be predetermined relative to the baseline of the scanner's document drum according to its final layout. It is necessary to have a certain angle.

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 mounted on the original drum 1, it must be mounted diagonally with respect 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 to the film 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 will be disadvantageous.

The present invention has been made in view of the above circumstances, and provides a document pasting device for a color scanner drum that can accurately and easily paste a color document onto a color scanner drum at an angle according to its appearance. The purpose is to

That is, the present invention provides a projection device in which a light source, a document rack having a reference line for setting a document at a certain angle, a projection lens, and a presentation mount rotatable within a plane are arranged in sequence; It is pivotally supported by a shaft provided near the presentation mount, has a document holding piece attached to its tip, moves in parallel along the shaft, and connects the document holding piece to the top surface of the presentation mount and a color scanner drum (described later). a rotating arm that reciprocates and rotates the color scanner drum; and a support that supports the color scanner drum so that its axis or reference line is parallel to the reference line on the document rack. The present invention provides a document pasting device for a color scanner drum.

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

FIG. 3 shows the main parts of a document pasting device for a color scanner drum according to the present invention.
The projection device 10, which constitutes a part thereof, includes a box 11 containing a light source (not shown), a document rack 14 having a reference line for setting the document "a" at a certain angle, for example, the innermost straight part 13, lens 9
and a display mount 15 on a disc, for example, which is rotatable within the plane of the device main body 12 and movable in parallel in the left, right, front, and back directions, are arranged in sequence. Further, the projection lens 9 is vertically movable along with the box 11 and document shelf 14 toward the presentation mount 15 via a groove 17 provided on one side of the column 16. The magnification relationship with the format placed above can be adjusted. Note that this magnification is displayed on the display device 18 immediately as the projection lens 9 moves up and down. As shown in the figure, a sand glass pad 15a and a reference line 15b parallel to the sand glass pad 15a are placed on the top surface of the appearance mount 15.
may be provided.

A shaft 20 is provided upwardly along one side of the formatting mount 15 on the support 16 side, preferably parallel to the reference line (or the innermost straight portion 13) of the document rack 14, and the base end is pivotally supported on this shaft 20. A rotating arm 19 is provided. A document holding piece 21 is rotatably attached to the tip of the rotary arm 19, and the document holding piece 21 holds a color document "a", which is turned over as shown in FIG. The color scanner drum 222 can be transferred to the surface of the color scanner drum 222 in this state. The rotary arm 19 can be expanded and contracted in the axial direction according to the position and diameter of the drum 22.

A drum support 23 is provided via a frame 24 on the side of the presentation mount 15 and along the shaft 20, and the color scanner drum 22 is attached to the shaft or surface of the drum support 23. The document shelf 14 is rotatably supported so that the reference line 22a is parallel to the innermost straight portion 13 of the document shelf 14.

Note that the positions of the shaft 20 and the drum support 23 are not limited to the illustrated example, and may be provided at any position near the presentation mount 15.

Next, a description will be given of the operation for pasting a color original "a" onto the circumferential surface of the color scanner drum 22 at a predetermined angle according to its appearance using this color scanner drum original pasting device.

First, for example, the color document "a" shown in FIG. 5a is turned over as shown in FIG.
Then, turn it upside down and fix it correctly with tape "C" etc. on one sand glass "b", and then stack the other sand glass "b'" on top of it, then turn it left and right as shown in Figure 5 c. Turn it over. In this state, as shown in FIG. 3, the sand glasses "b" and "b'" are set on the document rack 14 so that one side of the sand glasses "b" and "b'" abuts parallel to the innermost straight portion 13.

On the other hand, as shown in FIG. 6, the format 25 is set on the format mount 15 so that its positioning register marks 25a are parallel to the format reference line 15b, and the format 25 is fixed with adhesive tape or the like.

Next, project the color original “a” onto the format 25,
The lens 9, document shelf 14, etc. are moved up and down, and at the same time, the format mounting table 15 is rotated, and the magnification and angle are adjusted so that the color document "a" and the image in the format 25 completely match. After the rotation of the appearance mount 15 is fixed with tape or other stopper means (not shown) at the time when they match in this way,
Take out the sand glasses "b" and "b'" from the document shelf 14, turn them over to the left and right so that they are in the state shown in FIG. Set on the display mount 15 so that one side of "b" and "b'" are aligned.

Next, remove one side "b'" of the sand glass, move the rotary arm 29 above the color document "a", and tape the color document "a" from above the sand glass b to the bottom surface of the document holding piece 21 at the same angle. Or transfer and fix by any other adsorption means.

Next, the rotary arm 19 holding the color document "a" is moved along the shaft 20 in the direction of the color scanner drum 22, and as shown in FIG. 4, the rotary arm 19 is rotated in the direction of the color scanner drum 22. Then, the color document "a" is turned over and pasted onto an arbitrary position on the circumferential surface of the color caster drum 22 via tape or the like. As a result, the color document "a" can be pasted onto the color scanner drum 22 accurately at the desired angle.

As described in detail above, according to the present invention, it is possible to measure the magnification for the appearance of a color original, and at the same time, it is possible to directly paste the color original onto the color scanner drum at an accurate angle according to the appearance.
A color original can be simply and easily pasted onto a color scanner drum.
