Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a layout method for input images in a layout scanner used in a plate-making process.

(Prior Art and Problems) Conventionally, layout work using a layout work machine has been performed according to the following procedure.

(1) First, as a preparation step, one or more original images are pasted on the input drum of the original image input section at the required angle, and the original images are photoelectrically scanned to create a margin for the image size that is considered necessary within the original image. The provided rectangular area is used as a trimming area for scanning the original image, and image data within that area is input to the storage device of the layout scanner.

(2) A layout trimming frame into which each image is to be fitted is displayed at a position corresponding to the designated layout position on the color monitor of the layout scanner.

(3) Load the image data in the trimming area on the scan of each original image onto the color monitor, move it while referring to the layout trimming frame corresponding to that image, fix it at the desired position, and calculate the position ( Layout position designation work (to be described later), layout image data within the trimming frame is recorded at the determined position in the output image storage device (final page creation).

By repeating these operations for all images, the layout operations for each image are completed.

The layout work performed by the layout scanner described above has the following problems.

(1) Since the trimming area for scanning the original image is wider than the area ultimately required, the original image storage capacity of the layout scanner increases accordingly.

(2) Since the positioning of each image to the layout cropping frame is performed on the color monitor, it is not possible to specify the position with an accuracy higher than the display resolution unit of the color monitor. This is particularly problematic when displaying and positioning layouts.

(3) The layout scanner is not a system for only doing layout work, but also changes the entire or partial tone of each image, changes the chromaticity, and partially corrects both images.
It is a very expensive system that can perform image processing such as combining two images and rotating both images.

Generally, the task is to read the input image data onto a color monitor, and while looking at the color monitor, refer to the layout trimming frame and specify where in the output image storage device it should be output (this will be used to specify the layout position from now on). Normally, a layout scanner is used to carry out the process (referred to as "work") using a layout scanner, and then the layout scanner is used to rearrange the image data group at a predetermined position (creating the final page).

However, the way to use such a layout scanner is to use another device to specify the layout position of the input image data, and then rearrange the image data group at a predetermined position based on the layout position data. The productivity of the layout scanner is lower than that in the case where only the final page (creating the final page) is performed by the layout scanner.

One method to overcome the drawbacks of layout work using such a layout scanner is disclosed in Japanese Patent Application Laid-Open No. 59-58.
This is proposed in Japanese Patent No. 430. However, this method has the following problems.

(1) Since feature points are set on the original image, operations are complicated.

(2) In the original image input section, by pasting the original image onto the input drum of the scanner and specifying only one feature point of the 1M image,
To give the original image position on the input drum.

For example, if the original image cannot be pasted onto the input drum at the correct angle, positioning accuracy will be significantly reduced. Furthermore, even if pasting is achieved at the correct angle, the coordinate resolution (especially in the rotational direction) on the input drum surface that the original image input section can provide depends on the resolution of the rotary encoder installed on the input drum rotation axis. Therefore, the accuracy is generally poor, and therefore, the positions of feature points cannot be given precisely.

(3) It is not possible to paste the original image onto the input drum with the required inclination.

(4) In general, one page of printed matter usually includes multiple original images, but with this method, it is necessary to specify the position on the input drum for each original image, so these can be printed all at once. Processing is complicated.

(Objective of the Invention) The present invention aims to eliminate the above-mentioned conventional drawbacks, and in particular, its main purpose is to improve the productivity of a layout scanner or reduce the cost of a layout scanner. .

(Means for solving the problem) When inputting image signals obtained by photoelectrically scanning an original image to the storage device of a layout scanner, a trimming area (hereinafter simply referred to as a trimming area) on the scan of the original image is input in advance. Then, when the original image is pasted directly or via an original image pasting sheet onto the input drum of the scanner, the position of the trimming area of the original image from the reference point is determined using an original image pasting device, etc., and the trimming area of the original image is determined. In addition to inputting the image data only for the inside, according to the layout specification sheet, also input the position data where the image data of the original image should be output within one page, and place each image at the position specified in the layout specification sheet etc. Make it possible to output to .

(Operation) Before photoelectrically scanning the original image, use an original image pasting device to designate the layout position based on a layout specification sheet, etc., determine the trimming area of the original image and its position, and then photoelectrically scan the original image. Since the image data of only the trimming area of each original image is input into the storage device of the layout scanner along with the output position data of the image data, the work of specifying the layout position in the layout scanner can be omitted.

(Embodiment) FIG. 1 is a block diagram showing an example of a configuration when an original image pasting device (1) is added to a plate-making layout scanner (50) to which the present invention is applied.

One or more original images (19) (shown in FIG. 2) are transferred to the input drum (11) of the scanner of the original image input section (51) using an original image trimming area determining means such as an original image pasting device (1) to be described later. ) (shown in Figure 2) at a desired angle, and determine the trimming area (29) (shown in Figure 6), which is the desired scanning area of the original image (19), and its position data. is sent to the original image input section (51), and image signals within the trimming area of each original image (19) mounted on the input drum (11) are sequentially input to the original image storage device (52).

In the layout section (53), the system disk (56)
The original image storage device (52)
), converting the address of the image data of the original image stored in ) and reading out the image data as is, the photosensitive material corresponding to the predetermined position specified in the layout sheet (26) (shown in Figure 3) It is stored in the output image storage device (57) so that it can be stored in the upper position.

For example, after finishing this layout processing for all the images that make up one page, the output image storage device (57
) are sequentially read out and input to the image output section (58) to store the laid out image on the photosensitive material.

In this way, by adding the inexpensive original image pasting device (1) to the layout scanner (50).

Responsible for designating layout positions, and at most checking the results on a color monitor (54);
Based on the results, the layout scanner (50) only performs the work of repositioning the image data group to a predetermined position in the output image storage device (57) (creating the final page), thereby improving the productivity of the layout scanner (50). The purpose of this is to reduce the cost of the layout unit (53) of the layout scanner (50).

The procedure will be explained below.

First, a layout specification sheet is created that defines the position, shape, size, and angle (orientation) of the trimming frame corresponding to each image (picture) in accordance with the page layout desired by the print orderer.

The layout specification sheet can be roughly divided into, for example,
It can be classified into the following two types.

The first type is a numerical value that specifies which image should be duplicated, at what magnification, and at which position (and in some cases, the angle), such as the position at which a specific point of the image should be duplicated. .

The other is a rough sketch that specifies which image should be reproduced (what size and magnification), what shape, what angle, and where to copy it (fill in numerical values as necessary). It is.

If you want to match the pattern with the trimming frame on the layout designation sheet with rough accuracy, use the layout designation sheet as described above, but if more precision is required, use an automatic drafting machine based on the rough sketch. For example, a formal layout sheet (layout sheet) (26) shown by the solid line in FIG. 3 is created using a layout sheet creation means such as .

In this embodiment, a case will be described in which a formal layout sheet (26) is created, but of course data from the layout designation sheet can also be used.

At this time, the origin of the layout sheet (26), the center points (Q,) to (Q4) of the trimming compatible rectangular area (27), etc. are drawn as necessary.

The data that created these layout sheets (26) are
The information is input directly or via a floppy disk or the like to the system disk (56) of the original image pasting device (1) and layout scanner (50) shown in FIG.

Each trimming compatible rectangular area (27a) (27b) (27c) (27d) of this layout sheet (26)
is transferred onto the original image (19) in consideration of the reproduction magnification, and this is the trimming area ((29) in FIG. 6) of the original image, which becomes the desired scanning area of the original image (19).

The work of transferring the trimming-ready rectangular area (27) of the layout sheet (26) onto the 1M image (19) is performed by the original image pasting device (1), which will be described later.

When the trimming area (29) of the original image is obtained, the original image (19) is input to the original image input unit (input unit 051 of the scanner).
The input drum (also referred to as input cylinder) (11) to be attached to the input drum (shown in Figure 1) (shown in Figure 2) is pasted onto the input drum (shown in Figure 2), and the work of determining the position of the trimming area (29) of the original image is also performed. This is done using an original image pasting device (1) which will be described later.

In this way, using the original image pasting device (1), the required number of original images (19) are placed onto the input drum (11) as shown in FIG. The developed drawing is shown), and the trimmed areas (29) of each original picture (19a) to (19d) are
a) Two points on ~(29d) ((Pl', P2'), (
pa', P4'), (P5', P6'), (pt'',
The positional data from the origin (0'') of Pa'') is determined and sent to the original image input section (51), and is used as a signal to select only the image in the required area.

Returning to Figure 1, in this example, there are four original paintings (19
The input drum (11) on which a) to (19d) have been pasted is removed from the original image pasting device (1) and placed in the original image input section (51).
), photoelectrically scans each original image (19a) to (19d), and trims the trimming areas (29a) to (29d) of the original image.
9d) Based on the position information of the above two points, the image data of only the trimming areas (29a) to (29d) of each original image is subjected to scaling processing according to the desired reproduction magnification.
M images are stored in both image storage devices (52).

Note that which original image data is stored in the original image storage device (52
) can be stored anywhere on the original image storage device (52) or on the system disk (56). ) may be input.

Each image data stored in the original image storage device (52) is
Trimable rectangular area of layout sheet (26) (
27), the area in which it is stored is known, and the position on the film at which it will be recorded when creating the layout sheet (26) is also known.

Therefore, an address for reading image data in one original image (19) from the original image storage device (52),
What is the relationship with the address for recording the image data in a predetermined position of the output image storage device (57)?

It is only necessary to add or subtract a constant value for each image in the horizontal and vertical directions.

In other words, although the original image storage device (52) and the output image storage device (57) are separate devices, both devices are usually magnetic disk devices and handle the same two-dimensional image data group. Since the only thing to be determined is which area of the original image storage device (52) is stored in which area of the output image storage device (57), address correction at the time of image data transfer can be performed both horizontally and vertically.

Only addition/subtraction correction of a fixed value is required.

In this way, the image data in the original image trimming area (29) of each original image (19) is transferred to the layout sheet (26).
The process of storing the image in the area of the output image storage device (57) corresponding to the position specified by is completed. However, if you output it to the image output section (58) as it is, the layout sheet (2
Since all the image data within the trimming compatible rectangular area (27) specified in 6) will be exposed and recorded, unnecessary parts of each image will be masked and only the image data within the trimming frame (28) will be exposed. need to be recorded.

For this purpose, when transferring image data from the original image storage device (52) to the output image storage device (57).

Either transfer the image data only within the trimming frame (28) of each image, or temporarily store the image data within the trimming compatible rectangular area (27) of each original image in the output image storage device (57), and then When outputting the image data from the storage device (57) to the image output section (58), it is masked so that the image data is only within the trimming frame (28) of each image, or when the image data is output from the original image input section (51). When storing the output in the original image storage device (52), it is conceivable to select and store image data only within the trimming frame (28) of each image.

These are basically the same concept, and the only difference is at what stage image data only within the image cropping frame (28) is selected (masked), so we will explain the above one case. do.

For example, to explain the first example, based on the data of the trimming frame (28) of each image drawn using an automatic drawing machine, one image is stored on the system disk (56) etc. as shown in Figure 5. It has a memory area corresponding to the effective recording area of the recording drum of the output section (58), and has a memory area corresponding to the effective recording area of the recording drum of the output section (58).
``'' ) to (28d'''), that is, within the trimming frame of each image, is set to 1, all other areas are set to O, and this is used as master data.

As mentioned above, each image has a rectangular area (27) that can be cropped.
(In Figure 5, (Pi"', Pt"), (p, #
#-P4"), (Ps"', Pt"), (Pt
", P, "')) are stored in distinct separate areas of the original image storage device (52), and an automatic drafting machine is used to create a cropping frame (28) for each image.
As shown in FIG. 5, the desired recording positions of the trimming frames (28a'') to (28d'') on the output film are known from the data drawn on the original image storage device (52). The address and the address of the output image storage device (57) have a 1:1 correspondence.

Therefore, the system disk (56) corresponds to the address of the area shown in FIG. 5 of the output image storage device (57) with 1=1.
) is sequentially read out from the beginning to the end, and the original image storage device stores only the portion where the numerical value is 1 (within the trimming frames (28a'') to (28d'') of each image). The image signal at the address (52) may be read out and stored at the predetermined address of the output image storage device (57).

The layout-processed image signal obtained in this way is
The image may be output as is to the image output section (58) and exposed and recorded on film, or directly using a cable or communication means, or indirectly via a magnetic disk back or magnetic tape. It is also possible to transfer the image to an image output unit other than the system and record the exposure on film there.

Next, an original image pasting device, which is an embodiment of the original image trimming area determining means, will be described.

This original image trimming area determining means is not limited to this embodiment, but in any case, according to the specified layout, the trimming area which is the desired scanning area of the original image is determined, and each of the trimming areas is determined to be a desired scanning area of the original image, and is applied to each original image mounting section of an original image input section such as an input drum of a scanner. Any means can be used as long as the original image can be mounted at a desired angle and position data specifying from where to where image data of the original image is required can be obtained from the 1M image input section.

In FIG. 2, a transparent glass stand (3) is fixed to an original image attachment part (2) located at the upper right corner of the main body (original image pasting device) (1).

An optical system (5) for projection imaging having an optical axis (R) that intersects with the glass table (3) at a proper point includes a light source (6) and a condenser lens (7) arranged above the glass table (3). It consists of a zoom lens (8), etc. arranged below the glass stand (3).

The input drum (11) of the scanner, which has been removed from the scanner body, is rotatably installed in the recess (9) formed on the left side of the original image attachment section (2).
A rotary encoder (13) that measures the amount of rotation of the input drum (11) from a reference point is disposed on the bearing (12) of (1). This input drum ('11) is removed from this device after pasting of the original image (19) is completed.
It is used by being attached to the scanner body.

When installing the input drum (11) to the scanner body, the rotational position of the input drum (11) must be completely aligned with the position where it is fixed in the bearings (12) and (12') of the original image pasting device (1). Installed to match. this is.

For example, a positioning groove is provided on the shaft of the input drum (11), and a bearing (12) (12') of the original image pasting device (1) is provided.
) and the input drum of the scanner body can be attached by providing a straight protrusion on the bearing that perfectly matches this groove).

A rear end portion of a first slide member (15) extending in the front-rear direction is attached to a left-right guide rail (14) fixed to the upper rear portion of the main body (1) so as to be slidable in the left-right direction.

The first slide member (15) has a second slide member extending in the left-right direction.
The right end portion of the slide member (16) is attached so as to be slidable in the front-back direction. On the left side of the second slide member (16), an arm (17) for attaching an original image is rotatably mounted around a single rotation part (S).

The original image is attached by attaching the 1M image (19) to the rear edge of the arm (17) using adhesive tape or the like and holding it by a member (21).

The amount of movement of the first slide member (15) in the left-right direction is measured by a rotary encoder (22) disposed near the guide rail (14). Second slide member (16
) in the front-rear direction is the amount of movement of the first slide member (15).
It is measured by a rotary encoder (23) disposed at.

A layout sheet stand (25) is supported by a rail (not shown) on the bottom plate (24) below the main body (original image pasting device) (1), and is disposed so as to be movable in the left-right direction and front-back direction. .

A layout sheet (26) shown in FIG. 3 is mounted on the layout sheet stand (25). As shown in FIG. 3, this layout sheet (26) includes a trimming frame (26) that defines the desired size, magnification, shape, position, and orientation (angle) of one or more original drawings (19) to be reproduced.
28), the y-axis circumscribing this, or a rectangle parallel to the y-axis (referred to as the trimming-compatible rectangular area (27)), the center point of the trimming-compatible rectangular area (27), and the origin are set in advance by an automatic drawing machine. It is drawn using etc.

Therefore, the coordinates of the four corners and the center of the rectangular region (27) for trimming are known in advance.

Note that the trimming frame (28) on the layout sheet (26)
) The reason for drawing the trimming compatible rectangular area (27) circumscribing the area is that since a scanner normally scans a rectangular area, the desired scanning area (trimming area) of the original image (19) in Fig. 6 is drawn.
This is to obtain (29).

Next, the operating procedure of the original image pasting device configured as described above and the coordinate relationship between the positions of the original image, the layout sheet, the input drum, etc. will be explained.

Returning to Figure 2, first attach the original picture (19), and attach the adhesive tape to the appropriate place on the ruler (17) to attach the original picture to the member (21).
Paste it with.

If the original picture (19) is of the transmission type, the film side should face downward, and in principle, the upper part (top) of the picture should be on the far side (negative side of the Y axis) of the original picture pasting device (1) in Figure 1. Paste it so that it is located in the direction). At this time, layout sheet (2
6) It is preferable that the image of the original image (19) projected onto the image is an erect normal image. Therefore, the optical system (5) for projection image formation is
The image of the original picture (19) is once imaged with a zoom lens (8) and then re-imaged with another lens (not shown).

If the original image (19) is a reflective type, the operating procedure will be different and will be explained later. First, a commonly used transmission type original image will be explained.

The layout sheet (26) is placed on the layout sheet stand (2
5) is fixed to the layout sheet stand (25) by vacuum suction or the like so that even if the layout sheet (26) and the layout sheet stand (25) are moved, the positional relationship between the layout sheet (26) and the layout sheet stand (25) is always constant.

During the operation, the center point (Q, ~Q
2) (hereinafter represented by Q) are sequentially made to coincide with the optical axis (R) of the main body (1).

If the positioning is to be performed automatically, first align the origin of the layout sheet (26) mounted on the layout sheet stand (25) with the origin of the main body (1), and then use an automatic drafting machine etc. to position the layout sheet (26). ) is performed by the driving means using the coordinate values of the center point (Q) of the trimming corresponding rectangular area (27) at the time of creation.

If the positioning is to be performed manually, the position of the optical axis (R) is at a fixed position with respect to the main body (1), so it is performed by projecting a pinhole or using a pointer as a reference.

In this way, among the one or more trimming-compatible rectangular areas (27) of the layout sheet (26), the first
The center point (Q) of the trimming corresponding rectangular area (27) (corresponding to the original image (19) attached to the arm (17) in the original image attachment) is aligned with the optical axis (R).

In this state (as shown in Figure 6), the 1M image is attached to the arm (1
7) and project the yX image (19) onto the layout sheet (26) at the desired magnification, the original image (19) projected within the trimming compatible rectangular area (27) of the layout sheet (26) This portion becomes the desired original image scanning area (JJK image trimming area) of the scanner.

In this device, if the magnification at which the original image (19) is to be reproduced is determined in advance, the desired reproduction area (29) of the original image (19) is created by adjusting the magnification at that magnification, or by adjusting the projection magnification if the magnification is not determined. Layout sheet cropping frame (2)
Place the original picture on the arm (17) so that it is positioned exactly within the
) by adjusting its position and angle.

Trimable rectangular area of layout sheet (26) (
27), the desired scanning area of the scanner (trimming area of the original image) can be determined.

In addition, the original image installation at this position is the X coordinate of the arm (17),
Rotary encoder (22), (23) to change the Y coordinate value
Read the values of its X and Y coordinates.

It is temporarily stored manually or automatically in a storage device (memory, floppy disk, etc.) in a computing device (30) provided in the main body (1). This can be placed on the scanner's input drum (11) or on the scanner's input drum (11).
This is data for determining the desired scanning area (29) of the original image (19) on the original image pasting sheet attached to the scanner.

Next, a method for determining the desired scanning area (trimming area) (29) of the original image (19) by the scanner will be described.

Let the coordinates of the center point (Q) of the trimming-compatible rectangular area (27) on the layout sheet (26) be (X□, yl).

Since the distance between the point (Q) and the two diagonal points (PL-pt) of the trimming corresponding rectangular area (27) is equal, the X-direction component and the y-direction component of this distance are expressed as ΔX,
Assuming Δy, the coordinates of points p, , p, are as follows (
(See Figure 7).

On the other hand, the coordinates of the point where the optical axes (R) intersect on the original image are (X'F

17), two points on the diagonal of the trimming area (29) of the original image (19) (Pt'*pg'
) (hereinafter abbreviated as point P F, p, j) are as follows.

P'(X'--,y'-grains) (3) ΔX m m p, z (xy + "w y' + "')
(4) m m Here, m is the replication (projection) magnification, ΔX, Δy are (1)
, has the same value as equation (2).

Thereby, the trimming area (z9) on the original image (19) can be calculated from the trimming-compatible rectangular area (27) of the layout sheet (26).

The above is a layout sheet (
26) The center point of the trimming compatible rectangular area (27) is
This is an example where the image is aligned with the optical axis (R), but if it is an image forming area of the projection imaging optical system (5), one image (9) and the trimming frame (28) of the layout sheet (26) Since the correspondence relationship is calculated, it can be matched anywhere.

For example, one corner of the trimming-compatible rectangular area (27) of the layout sheet (26) may be aligned with the optical axis (R).

Next, the original image (19) is pasted onto an appropriate position on the input drum (11) of the scanner, and the position of the trimming area (29) of the original image (19) on the input drum (11) is determined.

As mentioned above, the original image is attached by adjusting the angle and position of the arm (17) while projecting the original image (19) onto the layout sheet (26) at the desired magnification, and then attaching the original image (19).
is pasted onto an appropriate position on the input drum (11) of the scanner, and the position of the trimming area (29) of the original image (19) on the input drum (11) is determined.

As mentioned above, while projecting the 1M image (19) onto the layout sheet (26) at the desired magnification, the original image is attached by adjusting the angle and position of the arm (17) to place the desired reproduction area (19) on the original image (19). trimming area) on the layout sheet (2

2) Store the reading (xo = Yl+) of (23) in the storage device within the computing device (30).

Next, as shown in FIG. 8, the original image (19) is moved onto the input drum (11) of the scanner, and an arbitrary area on the input drum that is not pasted (original image (19)) is moved. )
In addition to pasting the original picture (19) with adhesive tape,
Rotary encoder (22) (23) at that position (

Generally, when moving the image (19) onto the input drum (11), the optical axis (R) and the extension line of the axis of the input drum (11) intersect, or in a close positional relationship. This will improve workability. Note that when using the apparatus shown in FIGS. 2 and 9, both a transmission type original image and a reflection type original image are pasted onto the input drum (11).

The former positional relationship is preferable.

Let (C) be the rotary encoder (22)
It is preferable that the reading of the unit movement amount in (23) and the reading of the unit movement amount of the rotary encoder (13) regarding the rotational movement of the input drum (11) are the same, and the explanation will be given assuming that they are the same, but they are different. If so, you can convert it.

Two points (pz't PI") on the diagonal of the trimming area (29) of the original picture (19) shown in FIG.
The coordinates of p,' (omitted) are as follows. In addition, when the optical axis (R) and the extension line of the axis of the input drum (11) intersect, the amount of movement of the rotary encoder (23) (

Therefore, as mentioned above, the coordinate values of the two points (p1=pg) of the trimming-compatible rectangular area (27) of the layout sheet (26), the readings of the rotary encoders (13) (22) (23), and the replication magnification ( m) is input, and the calculation device (30) calculates the trimming area (29) of the original image (19) to be obtained.

Note that a calculation device other than the original image pasting device (1) may be used.

The above description has been made regarding a transmission type original image that is commonly used, but the present invention can also be applied to a reflective type original image by changing the primary part.

That is, in the apparatus shown in FIG. 2, two light sources (6') are provided on the left and right sides of the layout sheet (26) at appropriate positions approximately 45 degrees to the optical axis (R). In addition, as shown in Fig. 9, the input drum (11) is connected to the reflection original image bearing (
12').

When the original image (19) is a reflection type original image, the input drum (11) is arranged so that the lower end of the drum is on the moving plane of the arm (17) for attaching the original image, as shown in FIG.

This is a reflective original painting (19) that is upside down on a glass stand (3) (with the image surface facing downward), the original painting is held on an arm (17), and a reflective light source (6') is used. After projecting onto the layout sheet (26) and positioning it, the reflection type original image (19) can be projected onto the layout sheet (26) and then pasted onto any position on the input drum (11) while maintaining that angle. This is to ensure that pasting is achieved while maintaining an accurate position of the image surface facing outward with respect to the input drum (11).

For this purpose, an input drum bearing (12'') for the reflective original (19) is provided.

Of course, the rotation amount of the input drum bearing (12') for the 1 reflection type original image (19) is the same as the rotation amount of the input drum (11) bearing (12) for the transmission type original image (19). (13), the origins of the bearings (12) (12') of both quad drums are made to coincide, and the amount of rotation thereof is always made to be the same.

If the original picture (19) is a reflective type, as will be described later, when holding the original picture (19) on the arm (17),
As a general rule, the top and bottom of the pattern are reversed.

However, it is desirable that the image projected onto the layout sheet (26) be an erect image. Therefore, it is necessary to insert a dope prism or the like into the optical system only when pasting a reflective original image. Then, the heaven and earth of the statue (
(up and down) is required.

After making such changes, the same as the transparent original.

Desired reproduction area (trimming area) of the original picture (19) (
Adjust the projection magnification equal to the duplication magnification and the position and angle of the original mounting arm (17) so that the image 29) is exactly located within the trimming frame (28) of the layout sheet (26).

To attach the original image, lock the arm (17) in that position.

To attach the original image at that position, after determining the X and Y coordinates of the arm (17), the original image attachment holding the original image (19) moves the arm (17) to the empty area of the input drum (11) (the original image ( 19) and paste it to any area where it is not pasted.

At this time, the reflective original image (19) is attached so that its image surface faces outward with respect to the input drum (11).

This means that the image pickup of the scanner is on the input drum (1
This is because it is carried out from outside of 1).

Afterwards, the reflective original image (1) on the input drum (11) surface
The position of the trimming area (29) in 9) can be calculated in the same manner as in the case of a transmissive original.

When pasting the reflective original 1i (19), the transparent original (1
There is another point that must be considered in distinction from 9).

This is because when pasting the reflective original image (19) on the input drum (11), the top and bottom of the original image will be the same as the top and bottom when pasting the transparent original image, so the fjk image is attached to the arm (17). When attaching the reflective original picture (19) to the
Do as shown. In addition, when pasting the original picture (19) on the original picture pasting sheet attached to the input drum (11), for example, in FIG. 2, instead of the input drum (11),
On the same plane as the glass stand (3), a flat stand that can vacuum adsorb the original image pasting sheet and a register pin for positioning are installed.
When the original image pasting sheet is attached to the input drum (11), a register pin for positioning is installed so that the origin of the input drum (11) and the origin of the original image pasting sheet attached to the input drum (11) match. All you have to do is set the position of .

Note that the position in the Y-axis direction of the trimming area (29) of the original image (19) on the input drum (11) is calculated from the readings of the two rotary encoders (13) (23); The position of the trimming area (29) of the original image (19) on the sheet in the Y-axis direction can be calculated only from the reading of the rotary encoder (23).

Further, when an original image is pasted on an original image pasting sheet, it is also possible to input image data of 1M image using a plane scanning type scanner.

(Effects of the invention) (1) The layout scanner can lay out the image data group at a predetermined position based on the layout position data obtained by the R image embedding device, so the layout position designation work in the layout scanner is omitted. I can do it,
The productivity of the layout scanner improves accordingly.

(2) Since image signals only within the trimming area, which is the desired scanning area of the original image, are stored in the storage device of the layout scanner, the capacity of the storage device can be reduced compared to the conventional art.

(3) The original image trimming area determining means optically projects the original image onto the corresponding trimming frame on the layout sheet, as shown in FIG. Also, when determining the reproduction magnification as necessary, more accurate position data is required than when determining the position data of the original image to be reproduced by specifying the layout position while looking at a color monitor.
