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 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. However, 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 is not cost-effective. This is because it is also disadvantageous in terms of time.

This 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 includes a projection plate provided with a reference line, a projection lens provided below the projection plate,
a display fixing plate provided below the projection lens and movable in a plane parallel to the projection plate; an adjustment mechanism for adjusting the distance between the projection lens and the display fixing plate; a color scanner provided on one side of the projection plate and supporting the color scanner drum so that its axis is parallel to the reference line of the projection plate; a nerd drum support device; a shaft provided parallel to the reference line of the projection plate;
One end is pivotally supported on the shaft, the other end has an original holding plate for holding a color original, and is provided so as to be movable along the shaft between the projection plate and the peripheral surface of the color scanner drum. The present invention provides a document pasting device for a color scanner drum, characterized in that it is equipped with a rotary arm having a rotary arm.

The present invention will be described below with reference to illustrated embodiments. In FIG. 3, reference numeral 11 is a projection plate made of glass or the like with a reflective surface of white color or the like, and a reference line 12 is drawn along one side of the projection plate. Note that the number of reference lines 12 is not limited to one, and a plurality of reference lines 12 may be provided in any direction. This projection plate 11 is fixed to a frame 13, and a projection lens 14 is also attached to the frame 13 below through a bellows 10. An appearance fixing plate 15 is provided below the projection lens 14 and parallel to the surface of the projection plate 11. A base line 16 parallel to the reference line 12 on the projection plate 11 is provided on the upper surface of the appearance fixing plate 15, and the base line 16 is parallel to the front and rear and left and right directions (that is, the XY plane) along a pair of shafts 17 and 18 that are perpendicular to each other. It is becoming possible to do so.

Further, a color scanner drum support device 19 held on the side surface of the frame body 13 is provided on one side of the projection plate 11, and a color scanner drum support device 19 is provided on one side of the projection plate 11.
is rotatably and detachably supported so that its axis (or reference line 28) is parallel to the reference line 12 on the projection plate 11. Note that the support device 19 is not limited to the illustrated example, and can be attached to the frame 13 at any other arbitrary position. Further, in front of the projection plate 11, a shaft 21 is provided, one end of which is fixed to a part of the frame 13 and extends to the front of the color scanner drum 20 in parallel with the reference line 12 of the projection plate 11. One end of the rotary arm 22 is pivotally supported on this. A document holding plate 23 is fixed to the other end of the rotary arm 22 for holding a color document by tape or suction. The rotating arm 22, the color scanner drum support device 19, the projection lens 14, and the projection plate 11 are integrally moved vertically in the direction of the presentation fixing plate 15, or the presentation fixing plate 1
5 up and down in the direction of the lens 14, or by moving both up and down, the distance between them can be adjusted, and the magnification for the format layout of the color original can be specified. Note that a pair of light sources 2 are provided diagonally above the appearance fixing plate 15.
4 is provided to illuminate the form fixed on the form fixing plate 15.

Next, the operation for pasting a color original onto a color scanner drum using this color scanner drum original pasting device will be described.

First, the format 25 is positioned on the format fixing plate 15 so that the pair of opposing register marks 26 are parallel to the base line 16, and fixed with tape or the like. The form 25 fixed in this manner is illuminated by the light source 24 and projected onto the projection plate 11 via the lens 14 (see FIG. 4). At this time, the pair of registration marks 26
is also parallel to the reference line 12 of the projection plate 11. Next, the color original 27 is placed on the projection plate 11, and the magnification of the color original 27 and the predetermined insertion section 25' in the projected appearance 25 is determined by vertically moving the appearance fixing plate 15 or the frame 13 that supports the lens 14. ,
While adjusting the focus, move the color original 27 onto the projection plate 1.
Adjust the angle etc. on 1 to make them match perfectly (5th
(see figure). Next, the rotating arm 22 is moved along the shaft 21, the color original holding plate 23 is then rotated onto the projection plate 11, and the color original 27 positioned as described above is held in that state by tape or suction. It is held by this holding plate 23 (see FIG. 6). Then, the rotary arm 22 is moved along the shaft 21 again to the color scanner drum 20.
The color original 2 is placed on a predetermined position on the circumferential surface of the drum 20 by moving it in a predetermined position and then rotating it at a predetermined position.
7 and fix it with tape etc. (7th
(see figure). This allows the color original 27 to be pasted onto the color scanner drum 20 in a state that accurately matches the angle of the layout.

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.
To simply and easily paste a color original onto a color scanner drum.

In the above embodiment, the format fixing plate 15 was described as being able to move in parallel only in the in-plane X and Y directions, but the present invention is not limited to this, and may be made to be able to rotate along the plane.
