Description

DETAILED DESCRIPTION OF THE INVENTION Recently, 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.

Color scanners equipped with this kind of editing function are generally called layout scanners, and after inputting the original image, they can output the image by exposing it on film at a specified position and with specified trimming. .

In order to attach a document to such a layout scanner, it is necessary to make the document have a predetermined angle with respect to the base line of the document drum of the scanner according to the final layout. This is due to the following reasons.

In other words, as shown in FIG. 1, when the document C311 is attached to the document drum (to) straight with respect to the straight line c of the document drum, the film attached to the exposure drum (c) after being scanned is (The image is straight compared to the image C exposed at 34J (51 is also the linear width of the exposure drum).

Therefore, in order to fully utilize the function of this scanner to process color separation and color separation at the same time, as shown in Figure 2, the η of the image diagonal to the straight line (G) of the exposure drum is required. If the original G11-'& is attached to the original drum (3o), the straight line 0 of the original drum
It must be installed diagonally to 4. this is,
When such a scanner body scans a document and then exposes the film on the exposure drum, the scanner itself has a function that rotates the scanned image at an arbitrary angle relative to the document before exposing it. This is because there may be cases where it has not been done.

It is technically possible to perform angular rotation in the computer that processes information for page collection, and some have adopted it, but this is due to the increase in the capacity of the computer itself, the increase in processing time, or the rotation process. Since problems such as a decrease in resolution occur, there are disadvantages in terms of cost, time, and quality.

Further layout information is required to obtain the final edited output using the layout scanner. This layout information requires information that allows determining the position of the trimming frame and outputting the output image to a predetermined position within the trimming frame.

Conventionally, in order to obtain this layout information, the trimming frame and original image are reproduced on a monitor TV, the trimming frame and/or the original image are moved, the trimming frame is placed at a predetermined position, and the trimming frame is placed at a predetermined position within the trimming frame. It was common to obtain layout information by arranging the original image at the position.

The reason for adopting such a method is as follows. In other words, the finished size of a manuscript image is generally larger than the size of the manuscript itself, and the trimming position within the manuscript image is determined arbitrarily to some extent, while the trimming position and dimensions within the editing page are This is due to the fact that numerical processing is possible from the base point within, but numerical processing is difficult for the position of the image on the document. That is, the image of the original is generally smaller than the finished size, and it is difficult to numerically determine the trimming start and end points.

When obtaining layout information using the conventional method described above, it is generally necessary to operate expensive equipment for a long time in order to obtain layout information, which is one of the causes of reduced operating efficiency of the equipment. .

Furthermore, in the conventional method described above, it is also known that the layout position is determined by visually confirming the position of the image of the document within the trimming frame by displaying it on a monitor TV, and then comparing it with the position of the layout image on the layout specified paper. However, the accuracy of this method is not good.

The present invention eliminates the drawbacks of the conventional methods as described above, enables numerical processing of the layout position of images on a document, and also allows data necessary for layout to be obtained accurately and easily without using expensive equipment. The purpose is to improve the operating efficiency of expensive equipment.

The present invention will be explained in more detail below.

In the present invention, if necessary, an auxiliary piece (2) is attached to the original (1) as shown in FIG. If the original (1) has a part where a reference point or reference line can be placed, there is no need to attach this auxiliary piece (2).

However, since it is preferable not to perform any unnecessary processing on the original, we will explain the case in which the auxiliary piece (2) is attached below, but it is not limited to this. Lines may be applied. Any means Z can be used to attach the auxiliary piece (2) to the original (1), and as shown in FIG. 6, it is easy to use an adhesive tape (51) such as cellophane adhesive tape.

An appropriate position for attaching the auxiliary piece (2) may be selected in consideration of the output image.

The document +11 with the auxiliary piece (2) attached is attached to the transparent plate (3) as shown in FIG. This attachment can be carried out extremely easily by using an adhesive tape such as cellophane adhesive tape.

In this way, the original (1) was removed and attached to the transparent plate (3);
For the purpose of protecting the original (1), preventing the original (1) from warping, and for other purposes, the original (1) may be
) may be placed in between, and a transparent plate (4) may be further stacked.

In this way, the transparent plates (3) and (4) were attached to the original (1).
) is loaded onto the document rack (5) of the projection device as shown in FIG. The throwing device shown in FIG.
, a projection lens (8), and a projection plate (9) are arranged in this order. In the figure, the light source is covered by a cover (7) so as not to dazzle the operator.

When loading the transparent plate (3) to which the original (1) is attached as described above onto the original shelf (5), the transparent plate is attached so that the transparent plate () is always located at the predetermined position on the original shelf. Stop (6)
, +61' are provided.

Further, an arbitrary point on the original (1) or the auxiliary piece (2) is set as a starting point (P). (The position of P is original (
Although it may be done at one point on the draft, we will explain the case where it is done on an auxiliary piece for simplicity. ) In the present invention, the transparent plate (3) with the original (1) attached as described above is loaded onto the original shelf (5) and the image of the original is projected onto the projection plate (9).

The light source, document shelf (5), and projection lens (8) can be moved together in the direction of the projection plate (9), and the projection lens can also be moved independently in the direction of the projection plate (9). ing. This allows adjustment of projection magnification and focus.

On the other hand, the upper button of the projection plate (9) is used to place the layout designation paper (2), and set the projection magnification so that the layout image (21) applied to the layout designation paper (2 and adjust the position of the designated layout paper.

In this state, the finished magnification of the original is measured to obtain magnification information. Since an automatic magnification measuring device that can automatically measure magnification is known, magnification information can be easily obtained by employing this device.

αJ in FIG. 4 is this automatic magnification measuring device, and the magnification is automatically displayed on this device. Alternatively, the magnification information may be obtained separately by any other arbitrary means.

In the present invention, the input start point (P
) of the projected image (PY) (see FIG. 5).

Note that the trimming frame 1, (
The position information of Bl, (C1, (Dl) is obtained in advance.

The positional information of the original input starting point IP+ on the layout designated paper is determined as the positional information of the projected image (Pr) as described above.

It is possible.

When obtaining position information using an XY digitizer, position information can be obtained by moving a cursor to a location to be measured.

The obtained input starting point on the manuscript (position information, magnification information, and position information of the trimming frame on the specified layout paper of pi controls the input to the layout scanner of the manuscript and the output from the layout scanner, which will be described later). used for

As already mentioned, it is convenient if the original is attached at a predetermined angle beforehand to the original drum, since there is no need to rotate the input image information.

Means for attaching a document to a document drum at a predetermined angle are disclosed in Japanese Patent Application Laid-Open No. 55-21033 and Japanese Patent Application Laid-Open No. 55-33.
No. 15, JP-A-55-50235, JP-A-Sho 5
It is described in Japanese Patent No. 5-64238, etc., and may be selected as appropriate. By the way, the registration mark marked on the layout designation sheet is often used as a coordinate reference for plate making, so an example of using it to create a reference line for attaching to the document drum is as follows. Become. The facing registration mark (inside, (151 or (16)
, (16) are applied. When the projected image and layout image match, these facing registration mark marks (15
), (19 or (16), (In) and the straight line obtained by connecting the transparent plate locking portion (6) or (6F') is determined in advance.

Next, remove the transparent plate (3) from the document shelf (5), and with the document (1) still attached, press the transparent plate locking part (
6) or +61' so that the angle formed by the parallel or perpendicular straight line is the angle formed by the straight line obtained by connecting the facing register marks found above and the transparent plate locking part. Then, a reference line (43) is drawn on the auxiliary piece (2). Any means can be used to determine the angle, and any known means may be used as appropriate, but as shown in FIG. Product name: Universal ruler Q (l) called Drafter
It is convenient to use.

To apply the reference line (4) to the auxiliary piece (2), first find the angle using a universal ruler, and then use the original retaining part (6) on the transparent plate.
), +61' are in contact with the document locking part (6), (
The transparent plate locking part (Il
It can be easily applied by placing the transparent plate on a transparent plate mounting table aε having 1, tut', and flll''Y and using the front symbol maaw.

The top of the transparent plate mounting stand (I81 is a light table (121)
This makes it easy and convenient to work with.

As already explained with reference to FIGS. 1 and 2, this reference line (43) is a standard for determining how much the original should be tilted with respect to the straight line of the original drum when the original is attached to the original drum. The document is attached to the original drum so that the reference line (43) is parallel or perpendicular to the straight line of the original drum.The reference line (43 is parallel to the straight line of the original drum) Whether it is set at a right angle or at a right angle depends on the required layout information, so it is determined as appropriate.

After the original (1) is mounted on the original drum in this way, the original image is input to the layout scanner and the layout scanner based on the input starting point (P) on the original as determined above, the position information on the designated 9-layout paper, and the magnification information. Controls the output position of the output image.

Furthermore, by using the input cropping position information, it is possible to determine the cropping of the output image.

Control of input and output of the layout scanner is performed as follows.

First, after attaching the manuscript to the manuscript drum, input start point tp+
Start inputting from , and store the image information in the storage device. In this case, the input image is wider than the required cropping area. The stored image information is called up and displayed on a monitor television, and after undergoing necessary processing such as checking the layout and correcting the tone, it is stored again in the storage device.

The image information that has been subjected to the necessary processing and stored is outputted by an output scanner with its output position controlled based on the positional information of the input starting point (Pl) on the layout designated paper.

Output control is performed as follows. First, the coordinate system X'-Y' on the exposure drum is set, and the position of the film (340) mounted on the exposure drum is controlled by the coordinate system x/y/ (see Figure 6). '
The y/coordinate system corresponds to the X-Y coordinate system of the layout designation sheet, and is set so that, for example, the X' axis is in the axial direction of the exposure drum, and the Y' axis is in the circumferential direction of the exposure drum.

The positional information of the input starting point tP on the manuscript on the layout designated paper is obtained in advance as the positional information of the projected image (pr), so it is stored in the first storage location of the inputted and stored image information. , the image information x′
It becomes possible to correspond to the point (PF) in the -Y' coordinate system. Actually, since this information is outside the trimming area, no output is performed in this area. The actual output is based on the position information of the trimming frame ((B), tc+, CI)), and the corresponding trimming frame (Af, (Br, tc'r, (D)) in the X'-Y' coordinate system, respectively.
An arithmetic unit determines whether or not the image is within the region r, and outputs the image at the required position with the necessary trimming.

As described above, according to the present invention, output according to the final finished layout can be extremely easily obtained using a layout scanner.

Further, according to the present invention, the output position and trimming position of an output image can be easily numerically processed without using an expensive layout scanner, and the operating efficiency of the expensive layout scanner can be improved.

In other words, since the trimming information and layout information are obtained in advance separately from the layout scanner, the layout scanner can create the required layout simply by automatically performing arithmetic processing according to the predetermined values. The processing is now complete, and there is no longer a need to perform layout processing on the monitor TV as in the past.
Operational efficiency will improve.
