Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a layout device for printing plate making, and more particularly to a layout device that layouts image data according to the contents of designated layout sheets.

(Prior art) In recent years, along with the color separation of documents using scanners, printed matter 1
2. Description of the Related Art A layout device for printing plate making that synthesizes image data for pages through computer processing is used in the field of printing plate making. This layout device is a scanner that is connected to a computer with a gorge editing function, and the image data captured by the scanner is fed to the above-mentioned computer, and after processing such as layout, it is output to the above-mentioned scanner. be.

FIG. 23 is a schematic diagram showing the configuration of a general layout device for printing plate making, and in the figure, 160 is a layout section;
70 is a tablet digitizer, 180 is a scanner section 0 As shown in the figure, the layout section 160 includes a computer 161 and a memo connected thereto.
3. Consists of a display 164, joystick 165 and keyboard 166, the tablet left digitizer 170 consists of a cursor 171, an input surface 172,
The input surface 172 has a mount area 173 and a menu area 174.
is set. The scanner section 180 is the input drum 18
1, output drum 182, and ink face 185.
186, and the ink faces 185 and 186 are connected to the combiator 161. Note that the computer 161 includes an input computer, a layout computer, and an output computer (all not shown).

In this layout scanner, editing work of image data is performed in the following manner based on various manuscripts, layout specification sheets, and other instructions. First, a document is pasted on the input drum 181 of the scanner section 180 at an angle specified by the layout designation paper, and the image data of the document is input to the input combinator (not shown) of the computer 161 via the interface 185 and stored in the memory 162. The 0 image data to be stored is captured from the manuscript in a range slightly larger than the actual trimming range based on the layout designation sheet (not shown), and accurate trimming is later performed using the layout computer (not shown) of the computer 161. .

A memory 162 in which image data has been written is separated from the input combinator and connected to the layout computer. As a result, the image data written in the memory 162 is displayed on the display 164. The operator observes this displayed image and moves the cursor by operating the joystick 165 while referring to the layout designation sheet to designate the trimming range, the position of the screen cover, etc. Further, the keyboard 166 is used to specify the magnification ratio, plate color, dot %, etc.

The data layout processed according to these specifications is written to the memory 163, so after the writing is completed, the data is laid out in the memory 163.
63 is disconnected from the layout computer and connected to an output computer (not shown) of computer 161. As a result, the data in the memory 163 is retrieved via the output computer and interface 186, and the trimmed and laid out image is output onto the film set on the output drum 182 of the scanner section 180.

Also, a joystick 165 and a keyboard 166
The above operations performed using the tablet can also be performed by operating the tab left digitizer 170. That is, the specified layout sheet is placed on the mount area 173 of the tablet digitizer 170, and the cursor 171 is operated to display the position data of the picture drawn on the specified layout sheet and various menus set in the menu area 174. Just select and enter.

Here, when capturing image data of a document from the input drum 181 of the scanner section 180, it is first necessary to paste the document onto the input drum 181 at an angle specified by the layout designation sheet. The pasting of this manuscript is carried out by the operator based on visual estimation. That is, the inclination angle of the figure drawn on the layout designation paper is measured with a protractor, and based on this measurement value, the angle of the document is confirmed using a protractor, etc., and the document is pasted on the input drum. Therefore, not only is the work complicated, but also the problem arises that it is not possible to paste the original at an accurate angle. In order to improve the work of pasting the original onto the input drum of this scanner, a magnification measuring machine with a function of projecting the original is used, and a data tablet is installed on the projection surface of this magnification measuring machine to mark the pasting line of the original. An apparatus for outputting a sheet on which a trimming range is drawn has been proposed by the present applicant as an invention in Japanese Patent Application No. 137434/1983.

Next, in the layout work using the computer 161, it is necessary to accurately trim the captured image data and give instructions for halftone dotting, etc. This layout work is performed by displaying the image on the display 164 and operating the twist stick 165, so the positioning of the trimming range tends to be inaccurate, which not only requires skill but also requires a long computer 161. There is a problem in that the expensive layout device for printing plate making cannot be used efficiently because it is occupied for a long time. Therefore, in order to improve this layout work, a patent application has been filed for a device that is equipped with a dedicated data input device, records various layout data on a recording medium, and provides the layout data to a computer via this recording medium to perform layout processing. Showa 5
This invention has been proposed by the present applicant as the invention of No. 9-213099.

(Problems with the prior art) However, the device of the above-mentioned Japanese Patent Application No. 137434/1982 and the data input device of the Japanese Patent Application No. 213099/1988 are separate devices, which not only makes the device expensive as a whole, but also There is a problem in that the magnification measurement work and the input work of various layout data are performed separately, and it is not always possible to perform the preparatory work efficiently before using the layout device for printing plate making.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and at the same time as measuring the magnification and angle of the original, it is possible to input various layout data specified by the designated layout paper, and based on this input data, the computer can layout the data. The purpose of this invention is to provide an apparatus that can perform the processing.

FIG. 1 is a schematic configuration diagram of an apparatus showing an embodiment of the present invention. In the figure, A is a document pasting sheet creating device, and B is a device for performing layout processing using data from the document pasting sheet creating device. This is a layout device. The original pasting sheet creation device A includes a magnification measuring device 1 and a magnification measuring device 1.
The CPU 14 includes a display 15, a keyboard 16, an XY plotter 17,

is a data tablet, 10 is an input surface of the data tablet 9, 11 is a cursor, and ■ is a projected image of a document.
A menu area 13b is set.

The projection lens 4, document holder 5, and lamp house 6 are held together by the support 3, and the magnification measurement is performed using the surface of the layout designated paper R3 placed on the surface of the workbench 2 as the projection surface of the document image. 1! The original placed in the original holder 5 is illuminated by a light source installed in the lamp house 6 through a suitable condenser lens, and the projected image of the image is assigned to the layout. It is designed to be projected onto the surface of paper R3.

Further, the projection lens 4, original holder 5, and lamp house 6 are configured to be movable up and down along the support 3, and are moved up and down by operating an operation switch (not shown). A projection image I obtained by reducing or enlarging the image of 1 to an arbitrary size over a predetermined range can be formed on the surface of the layout designated paper R5. At this time, the distance between the projection lens 4 and the layout designation sheet R5 is taken in by a linear encoder or the like, and the magnification is calculated through arithmetic processing and displayed on the magnification display 7.

Therefore, if a transparent original is placed in the original holder 5 and the projected image (■) is made to match the figure drawn on the designated layout sheet R3, the magnification will be automatically displayed on the magnification display 7.
Magnification measurement can be completed. Note that such an automatic magnification measuring device is well known.

Furthermore, data given from the magnification measuring device 1 is input to the CPU 14 via a signal input section (not shown).
At this time, the CPU 14 can import data and start arithmetic processing using the numeric keys provided in the first and second menu areas 13a and 13b of the data tablet 9, the keyboard 16, or the magnification measuring device 1. It is controlled by various operation switches (not shown), etc.

The input/output computer 27 and the layout computer 29 are connected to the fixed disk 28 via a connection switching device 33.

Next, the operation of the apparatus shown in FIG. 1 will be explained. Third
The figure is an explanatory diagram showing operations in the original pasting sheet creating apparatus A.

First, the layout designated paper R is placed on the mount area 12 of the data tablet 9.
5 (31), in the figure, layout designated paper R
3 and the mount area match. On this layout specification sheet R3, ruled lines indicating the range to be trimmed of the document and simple figures indicating the outline of the picture are drawn.

Therefore, the position data of the ruled line indicating the trimming range and various layout data are input using the cursor 11 (S2
) At this time, regarding the input of position data indicating the trimming range, a simple position data input method can be used if the trimming range is one of several predetermined shapes, for example, a rectangle. For example, the user selects "Rectangle" in the first menu area 13a with the cursor 11, and inputs only the two vertices of the rectangle, the upper left corner and the lower right corner, regarding the position. In addition, inputting various layout data is performed through the second menu area 13b;
The input through the second menu area 13b is data that will be used later in the layout device B (for example, document number, magnification, halftone coverage, etc.).In this way, the input using the data tablet 9 is performed via the CPU 14. The data is recorded on the floppy disk FD (33), and the floppy disk FD is transferred to the layout device B, where the recorded contents are used. Also, this recorded content is block 1
8 is given to the mask cutter 19 and used for character bridge shapes and burning, but since the characters are not particularly related to the trimming layout in the present invention, a detailed explanation will be omitted.

Next, an original such as a color film is set in the original holder 5 (S4), and an image I of the original is projected onto the surface of the layout designated paper B set on the data tablet 9 on the workbench 2.

Next, after inputting the original using the numeric keypad or keyboard 16 provided in the second menu area 13b (S5), operate the magnification adjustment switch (not shown) provided in the magnification measuring device 1 to specify the layout. The pattern of the original image (■) is made to be defeated against the layout designation figure drawn on the paper R3. Note that the positioning at this time is performed by shifting the layout designation sheet R3 on the workbench 2.

After this, the magnification measuring machine 10 magnification display switch (not shown)
When the operator operates , the magnification at that time is displayed on the magnification display 7, and the magnification data is taken into the CPU 14 and further recorded on the floppy disk FD (S6).

Note that, as already explained, the above operations are almost the same as in the case of a well-known magnification measuring machine, and the following operations are not necessary for documents that do not require angle setting or trimming range setting.

Next, when various positional data on the layout designation sheet R5 for calculating the original pasting angle and trimming range are input (
S? ) At this point, the CPU 14 starts processing the position data and the magnification data, and calculates the pasting line data and trimming range data of the original (58). Next, the sheet W of the pasting line and trimming range of this original is calculated. The above output position data is input and taken into the CPU 14 (39).

Here, when the sheet output switch (not shown) of the magnification measuring machine 1 or the keyboard 21 is operated, the CPU 1
The data from 4 is sent to the control circuit of the XY block 17, and the XY plotter 17 starts the graphic output operation. The copy is completed (SIO).

After this, when performing magnification measurement work for the next document, return to step S4 from step 311 and perform the operations up to step 310. In this case, when inputting the output position data in step S9, the sheet W is Since a figure indicating the pasting line and trimming line of the document inputted up to the operation is drawn, the desired output position data can be easily input by referring to this figure.

In this way, the work of measuring the magnification of a predetermined document is repeated, and when the series of work is completed, the end operation is performed (Sl
l).

FIG. 4 is an explanatory diagram of the menu setting operation performed prior to data input in step S2 of FIG.
1) Next, the menu area is divided and menu items are assigned to each divided area (S22).

FIG. 5 is an enlarged view of the input surface 1o of the data tablet 9.

As shown in the figure, a mount area 12, a first menu area 13a, and a second menu area 13b are set on the input surface 10. The mount area 12 is located at the cursor 1 according to the layout specification sheet RS.
It is set by inputting three points, A1, A2, and A3. The layout specification sheet R3 itself is used to input position data. In the first menu area 13a, frequently used figures on the data tablet 9 are set as items. Here, each item is a rectangle, a circle, a polygon, a straight line, etc.

The mount area 12 and first menu area 13a described above are provided in a normal data tablet.

In contrast, the second menu area 13b is newly introduced in the present invention. However, since the numerical input has been conventionally used, the part excluding the numerical area has been added according to the present invention. The menu items include layout items such as pattern number, magnification ratio (%), halftone dot %, lively color, plate color, specific point, and operational items such as terminator and end point. Color items C (cyan), Y (yellow), M (
magenta) and K (black). In order to provide an area for these items plus 0 to 9 for inputting numerical values, a decimal point, and TAB indicating the delimitation of numerical values, a second menu area 13b is set by points B1, B2, and B3, and this is divided. Assign each of the above items to each divided area.

Through this menu setting operation, the data tablet 9 having the functions required by the layout device B according to the present invention is set.

FIG. 6 is a flowchart showing the data input operation performed using the data tablet 9 on which the above-mentioned menu is set and the operations based thereon, and the data input in step S2 of FIG. 3 will be explained according to this flowchart.

First, the plate plane coordinates are input (331). The plate coordinates are the coordinates of the mount area, and refer to Al-A3 shown in Figure 3. Input these three points with the cursor 11. Next, input the plate color (332). The plate color is 10% cyan. in this case,
The cursor 11 is used to sequentially specify "plate color", rCJ, "1", rOJ, and rTABJ in the second menu area 13a.

After inputting the plate color, input the figure (S34).
, the figure refers to a figure indicating the trimming range and other figures drawn on the layout designation sheet R9, and is assumed to be a rectangle here. Therefore, following "Rectangle" in the first menu area 13a, the two vertices at the upper left and lower right of the rectangular trimming range on the layout designation sheet IIs are input using the cursor 11, respectively.

This figure can be either a picture or a mesh. In the case of a pattern, image data will be imported from the original later,
In the case of a rope tie, it will be filled in with the specified color.

Therefore, it is necessary to judge whether or not the screen is closed (535), and an operation is performed accordingly.

If it is not a mesh, it is a picture, and in this case, input the picture number (536), input the magnification (S37), and input the specific point (S38).The picture number manually is the "picture number",
Perform the operation "1", rTABJ (in the case of picture number l), and input the magnification ratio "variable magnification", rlJ, "2",
rOJ, rTAB" (when the magnification is 120%), and the specific point input points to a predetermined point on the layout designation sheet R5 following "specific point".

Note that the picture number is the same as the original light input in step S5 of FIG. 3, and the input of the magnification ratio is omitted when measuring the magnification in step S6 of FIG. 3.

In addition, in the case of a net tie, input the color of the rope tie (S39).
), this is "Tsunafuse", rcJ, "1", "0", r
Perform TABJ, rYJ, "2", rOJ, rTABJ (in case of 010%, Y20%).

After this, please judge the presence or absence of living lines (frames for pictures, etc.).
40) If there is a living line, enter the color of the living line (S41), this is "lively", rMJ, "5",
"0", perform rTABJ (in the case of Ikigoiro M50%).

Subsequently, by instructing the "terminator" (S42), the flow returns to the repetition point. The above-described operations can be performed on a new figure unless an instruction is given to "end". Further, when "end" is instructed, the data input in step S2 in FIG. 3 ends.

In step S3 of FIG. 3, all of the data input in this manner are recorded on the floppy disk FD of the document pasting sheet producing apparatus shown in FIG.

Note that the order of arrangement of each step in the flowchart shown in FIG. 6 is an example, and it goes without saying that the order can be changed.

Further, the data input operations performed using the data tablet 9 are performed only for the plate plane coordinate input in step 331, the figure input in step 334, and the specific point input in step 338 shown in FIG. 6, and other operations are performed using a dedicated In inputting various layout data using a dedicated input device, which may be performed using a simple input device such as a personal computer, first, data is inputted using the data tablet 9 and recorded on the floppy disk FD. The position data is given to the dedicated input device and displayed on the attached display. This display is performed for each layout frame drawn on the layout designation sheet Its. Next, for each frame shape, data such as plate color, pattern number, magnification ratio (no need to input if input in step S6 of FIG. 3), halftone color, lively color, etc. is input. These input data are then recorded on the floppy disk F[l and provided to the layout device B.

The reason for inputting various layout data using a dedicated input device in this way is that many of the various layout data are not position data, and data other than these position data is input by operating the data tablet 9. than,
This is because it is more efficient to input using a dedicated input device. Furthermore, by using this dedicated input device, it goes without saying that the document pasting sheet creating device can be used efficiently.

FIG. 7 is an explanatory diagram of the input points on the data tablet 9 in step S7 of FIG.
On the data tablet 9 provided in the
is placed on the layout designation sheet R3, and a printing plate line H forming a rectangle and a layout designation figure E are placed on the layout designation paper R3. The projected image (■) is projected so as to match the figure E.

First, the position data of two points P1 and P2 on the printing plate line H drawn on the layout designation sheet R3 is input using the cursor 11.

This printing plate line H corresponds to the reference line when attaching the original to the input drum of the scanner.
Using the cursor 11, input position data of rectangular vertices R1, R2, R3, and R4 forming the rectangular vertices Q1, Q2, Q3, and
Input the position data of Q4 using the cursor 11. These position data can be input to the CP by operating the operation switch (not shown) of the magnification measuring device 1 or the keyboard 21.
Taken into U14.

FIG. 8 is an explanatory diagram showing the positional relationship of each point inputted from the data tablet 9 in step S7 of FIG. will be explained in detail.

Two points P1, P on the printing plate line H in the X-Y coordinates shown in the figure
If the coordinates of 2 are PI (a, b) and P2 (c, d), then the inclination θ of the plane line H with respect to the coordinate axis X is −b tan θ−□ ■ −a.

Here, if the origin is PO (w, z) and the new coordinates whose coordinate axes are the plane line H and the line orthogonal to this are X-y, the coordinate conversion formula from the X-Y coordinate to the x-y coordinate is It will look like this:

X=xcosθ+y sinθ+W Y=-xsinθ+ycosθ+2 Than this becomes.

Also, since sin θ and cos θ are expressed as follows from the equation For example, the X-Y coordinate values of point R1 are replaced with the coordinate values of (XRI, YRI), ! -7 coordinate values are (xRl, yRl). Similarly, all points R2-R4 and Q1 to Q4 are obtained in xy coordinates.

Next, drawing coordinate values for drawing with the XY plotter 17 are calculated from these coordinate values.

The magnification obtained in the magnification measurement work is multiplied by m, the coordinate values obtained as a result of the above calculation are (x, y), and the drawing coordinate value is (Dx
SDy), then it becomes.

Therefore, the drawing coordinate values to be drawn in the XY block 17 can be obtained from the formulas (1), (2), and (2).

Figures 9, 10 and 11 are step S of Figure 3.

is displayed based on the document pasting line data calculated in step S8, and the trimming line 252 is displayed based on the document pasting line data calculated in step S8.
This is displayed based on the trimming range data calculated in . Further, the figure SA displayed on the display 15 can be moved arbitrarily within the outer frame 250 by operating a cursor movement key (not shown) provided on the keyboard 16.

Therefore, by operating the keyboard 16 and moving the figure SA to a desired position, the output position data in step S9 is input. This movement of the figure SA can be carried out, for example, by moving the figure SA to the position a1 indicated by the broken line in FIG.
This is done by moving the . Note that the predetermined position a
O is not limited to the lower right corner as shown in the figure, but can be set arbitrarily.

In addition, since the outline, trimming line, etc. of the document whose output position has been inputted up to the previous operation are displayed on the display 15, when inputting the output position data in step S9, the figure displayed at position aO may be moved to a desired position by referring to these display figures into which output position data has already been input.

19, 20, and 21 (al to tgl are flowcharts showing the contents of data processing by the layout computer 29, and this data processing positions the image data captured on the fixed disk 28. The processing contents of the layout computer 29 will be explained in detail below based on FIGS. 19 to 21.

First, the operator instructs the number of the image to be positioned using the display keyboard 30 (S51), and then
The image with the designated number is displayed in its entirety on the display 32 (S52).The floppy disk FD records the disk number in which the image is stored when it is input from the scanner unit 20, so it You can search for the desired image. Further, a thinning rate for displaying the entire image on the display 32 is calculated. Here, since various modes are displayed on the screen of the display 32, the various modes are selected by operating the mouse 31.

FIG. 20 graphically shows the modes that can be selected with the mouse 31, and the modes M1 to M7 corresponding to each graphic form a menu with the following contents.

hl: Menu for specifying a specific point on the display 32? 12: Menu for specifying the range you want to display without thinning out and performing split display? 13: Menu for measuring the dot percentage of the point specified on the display 32 R4: Layout specification sheet R of the point specified on the display 32
Menu 5 for measuring the coordinates on 3: Menu R6 for restoring the split-displayed image to the whole image: To end the display of the currently displayed image and move on to the image with the next document number. Menu R7: Menu for ending the display of the currently displayed image.The process moves to the keyboard with display 30. Therefore, first, mode Ml is set in order to make it possible to specify a specific point on the display 32. (S53) 0 Next, in step 352, it is determined whether the positioning of the image displayed on the display 32 has been completed (35
4) This judgment is made by checking the flag in the floppy disk FD.The 0 positioning is completed.
That is, when the specific point designation on the display 32 has been completed, the trimming range of the image on the display 32 is calculated based on this specific point (355).

Also, if positioning is not completed, display 3
The trimming range of the image on 2 is calculated so as to be in the center of the entire displayed image, and a specific point is calculated based on this (356).

Once the specific point and trimming range have been determined in this way, these are displayed superimposed on the entire image on the display 32 (357), and in this state, the mouse 31
It will wait for input from (558).

Input with the mouse 31 is performed by specifying a point on the screen of the display 32, but if the instruction with the mouse 31 is within the image area, it means that the specific point movement mode has been set (S59), and the instruction with the mouse 31 If it is a menu area outside the image area, one of modes M2 to M7 will be set.

FIGS. 21 fa) to 1gl are flowcharts showing the processing contents of modes A2 to M7, and the processing contents of each mode will be explained below based on the figures.

FIG. 21 (al indicates the specific point movement mode in step 359. In this case, when a point in the display image is specified with the mouse 31, the specified point becomes a new specific point and is displayed on the display 32. The specific point has moved (S60), and a new trimming range is calculated based on this new specific point (S61), and step 35
Return to 7.

The image to be displayed is an image without thinning, and up to three points can be specified. This means that four points in the largest image, including the specific point, have been designated. Then, the image is displayed on the display 3 centering on the specific point and the specified point.
This image is displayed in each quadrant on the display 32 without being thinned out.

Next, a specific point and a trimming range on the split display 32 are calculated (S73), and the specific point and trimming range obtained by this calculation are superimposed on the split display image in step 372. is displayed (374). After this, the M1 mode is set in preparation for specifying a specific point (S75), and the state waits for input from the mouse 31 (S76).

If the instruction of the mouse 31 is within the image area, the display 3
Is the specific point moving on S7? ), a new crop range is calculated (578), and the process returns to step 374.

On the other hand, if the instruction with the mouse 31 is a mode M3 to M7 outside the image area, the instructed mode will be set.

FIG. 21 (C1 shows a menu for measuring the dot percentage in mode M3. When mode M3 is designated by operating the mouse 31, the system first waits for coordinate input from the mouse 31. (S81), if the coordinates input from the mouse 31 are within the image, the halftone percentage of each color is displayed in CSM, Y, on the display 32 (582).
, return to step 581. This displayed dot percentage is calculated by the pixels (
For example, it is the average value of the values of 9 pixels).

On the other hand, when mode M1 for specifying a specific point is specified using the mouse 31 in step 381, step 35B in FIG. 19 or step 35B in FIG. (Proceeds to step S76 in BL 583) and waits for input from the mouse 31. Furthermore, in step S81, the menu for performing split display in mode M2 is valid only when full display is being performed, and the menu for returning to the full picture in mode M5 is only available when split display is being performed. Needless to say, it is effective.

FIG. 21 (dl is mode M4, that is, display 32
This shows a menu for measuring the coordinates of the point specified above on the layout designation sheet R3. When this mode M4 is designated by operating the mouse 31, the system first waits for an input from the mouse 31 (S91). If the coordinates input from the mouse 31 are within the image, the coordinate values of the point designated by the mouse 31 on the layout specification sheet R5 are displayed (592), and the process returns to step 391.

In the 0 diagram where the point indicated by PM is expressed as PM, the specific point p
The coordinates on the image data corresponding to s (xp, yp) are shown in FIG. 19 and FIG.
1, and further steps S71 to S37 in FIG. 21 (bl)
The result of positioning according to No. 8 is already clear. Therefore, based on the coordinate values of this specific point PS, the coordinate values (xs, ys) of the point PM on the layout specification sheet RS are calculated,
The results will be displayed on the display 32.

On the other hand, when the old mode for specifying a specific point is specified using the mouse 31 in step S91, step 35B in FIG. 19 or step 35B in FIG. The process moves to step 376 in step Cb) (593) and waits for input from the mouse 31. Also, in step 391,
The menu for performing split display in mode h2 is valid only when full display is being performed, and the menu for returning to the whole image in mode gate 5 is valid only when split display is being performed. Needless to say.

Figure 21+61 shows the mode M5, that is, the menu for returning the split-displayed image to the whole image.
When mode M5 is instructed by operating the mouse 31, the screen that is being split into parts is returned to the full display (5IOI);
Ml mode is set in preparation for specific point instruction (S102)
, the process returns to step S57 in FIG.

Figure 21+61 shows a menu for mode h6, that is, for ending the currently displayed image and moving on to the image of the next document number.When mode H6 is designated by operating the mouse 31, the current Search the information on the floppy disk FD for the number next to the number of the displayed manuscript, and
The number of the next positioning image is 5ill), and the process returns to step S52 in FIG.

Figure 21 (illustration shows a menu for ending the currently displayed image in mode M7; when mode M7 is designated by operating the mouse 31, the layout work for the currently displayed image is This ends, and the processing of the layout computer 29 moves to the keyboard with display 30 side.

When the trimming or positioning of the captured image data is completed, the layout combiator 29 processes the data recorded on the floppy disk FD, such as plate color, tethering, lively color, etc., and the processed data is After being stored in the fixed disk 28 again, it is output onto the output drum 22 of the scanner 20 via the input/output computer 27 and the interface 26, and film exposure is performed to create Y, M, and CSK film originals. The Rukoto.

(Effects of the Invention) As described above, in the present invention, it is possible to input various layout data specified by layout designation sheets at the same time as measuring the magnification and angle of the manuscript, and to create a manuscript pasting sheet.
