Abstract

PURPOSE:To efficiently operate a layout scanner by outputting simultaneously the variable power ratio of an original, the mounting line of the original and a trimming range at the desired position of an original bonding sheet. CONSTITUTION:The position data of two points P1, P2 on a printing plane line H drawn in an arrangement designating paper B is inputted by a cursor 11, and further, the position data of the tops Q1, Q2, Q3, !r of a rectangular shape indicating the trimming range in a projection image I is inputted. When the position data on the arrangement designating paper B is inputted, at this time, an arithmetic control part 20 starts to process the position data and magnification data, calculates the mounting line data and the trimming range data of the original and stores in a memory 23. The inclination of the mounting line to a reference line or the set angle data of the original F is simultaneously displayed on an angle display device. Then, the cursor of an XY block 30 with a digitizer is operated to input the output position of an XY plotter 31.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for creating a document pasting sheet for a scanner, which is used when performing color separation of various documents using a scanner, particularly a layout scanner.

(Technical background) In recent years, along with the color separation of originals using scanners, printed matter 1
Layout scanners that synthesize pages of image data through computer processing are used in the field of printing plate making.

This layout scanner is a scanner connected to a computer with a page editing function, and image data captured by the scanner is fed to the computer, and after processing such as layout, is output to the scanner.

FIG. 9 is a schematic diagram showing the configuration of a general layout scanner. In the figure, 160 is a layout section, 170 is a tablet digitizer, and 180 is a scanner section. As shown in the figure, the layout section 160 includes a computer 160
The tablet digitizer 170 consists of a memory 162, 1636, a display 164, a joystick 165, and a keyboard 166 connected thereto.
consists of a cursor 171 and an input surface 172;
2, a mount area 173 and a menu area 174 are set. The scanner section 180 includes an input drum 181, an output drum 182, a linear encoder 183, a rotary encoder 184, and ink faces 185 and 186, and interfaces 185 and 186 are connected to the computer 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 X-direction position data PX is sent from the linear encoder 183 and the Y-direction position data P is sent from the row encoder 184.
Along with Y, the image data of the original is taken into the input computer (not shown) of the computer 161 via the ink face 185 and stored in the memory 162. Image data is imported from the manuscript for an area slightly larger than the actual trimming area based on the layout specification sheet (not shown), and is later imported into the layout computer of the computer 161 (
(not shown) for accurate trimming.

The memory 162 in which image data has been written is separated from the input computer 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 operates the joystick 165 while referring to the layout designation sheet to move the cursor and specify the trimming range, the position of the netting, etc.
Further, the keyboard 166 is used to specify the magnification, plate color, line percentage, etc.

Since these data are written to the memory 163, after the writing is completed, the memory 163 is disconnected from the layout computer and connected to an output computer (not shown) of the computer 161. As a result, the data in the memory 163 is taken out via the output computer and the ink face 183, 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 digitizer 170 can also be performed by operating the tablet digitizer 170. That is, the above layout designation paper is set on the mount area 173 of the tablet digitizer 170, and the cursor 171 is operated to select the position data of the picture drawn on the layout designation paper and various menus set in the menu area 74. Just enter it.

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 scanning drum. Therefore, there has been a problem that not only the work is complicated, but also the original cannot be pasted at an accurate angle.

Next, in layout work using the computer 161, it is necessary to accurately trim the captured image data. This trimming work is performed by displaying an image on the display 164 and operating the joystick 165, so the positioning of the trimming range tends to be inaccurate, which not only requires skill but also requires a long time on the computer 161. There was a problem in that expensive layout scanners could not be used efficiently.

Therefore, in order to improve the above-mentioned work, a patent application was made in 1973 for a device that uses a magnification measuring machine with an original projection function to measure the magnification and output the original angle gauge.
It has been devised by the present applicant as an invention of No. 9-162108.

However, the device that outputs the angle gauge of the document described above cannot specify the trimming range, and the reality is that the trimming range is complicated to perform by displaying the image on the display 164. It is.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and it is possible to efficiently use a layout scanner by simultaneously outputting the magnification ratio of the original, the pasting line of the original, and the trimming range at a desired position on the original pasting sheet. The purpose is to provide a device that operates well.

(Summary of the Invention) To achieve this objective, the present invention provides a magnification measuring device that measures the magnification of the original by projecting the original into a specified size, and data that inputs the position data of the reference line and pattern on the designated layout paper. a tab left, an arithmetic control device that performs calculations based on magnification data from the magnification measuring device and position data from the data tab left, and calculates data of a document pasting line and a trimming range; and a calculation result of the arithmetic control device. The present invention provides an apparatus for creating a document pasting sheet for a scanner, which is equipped with an output device capable of outputting the document pasting line and the trimming range based on the above, and manually inputting the output position.

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 a projected image of the image is displayed. It is designed to be projected onto the surface of designated paper B.

Furthermore, the projection lens 4, document holder 5, and lamp house 6 are configured to be movable up and down along the support 3, and can be moved up and down by operating a switch on the operation control panel 7. The projected image I, which has been reduced or enlarged to an arbitrary size within a predetermined range, is placed on the layout designated paper B.
It is now possible to form an image on the surface of Then, at this time, the distance between the projection lens 4 and the layout designation paper B is taken in by a linear encoder or the like, and the magnification is calculated through arithmetic processing and displayed on the magnification display 8.

Therefore, if you set a transparent original on the original holder 5 and match its projected image (■) with the figure marked on the designated layout sheet B, the magnification will be automatically displayed on the magnification display 8 and you can measure the magnification. It can be terminated. Note that such an automatic magnification measuring device is well known.

The XY plotter 30 with digitizer has an XY block 31.
It is equipped with a digitizer surface 32 and a cursor 33, and can be controlled so that the output position of the XY plotter 31 comes to the position on the digitizer surface 32 that is input using the cursor 33.

FIG. 2 is a block diagram showing an example of a signal processing system in an embodiment of the present invention, in which data given from the magnification measuring device 1 and the data tab left lO is sent to the arithmetic and control unit 20 via the signal input section 15. However, the acquisition of data and the start of arithmetic processing by the arithmetic control unit 20 at this time are controlled by the numeric keys, push button switches, or keyboard 21 provided on the operation control panel 7. A drive signal is output to the block 30, a display signal is output to the angle display 9 and the magnification display 8, and the like.

Next, operations for setting the magnification ratio, angle adjustment, and trimming range of a document according to this embodiment will be explained.

FIG. 3 is an explanatory diagram showing the measurement procedure in the above operation.

First, after setting the layout designation paper B (or its copy) on the data tablet 10 on the workbench 2 (Sl),
When setting an original such as a color film in the original holder 5 (S2), an image of the original is placed on the surface of the designated layout paper B set on the data tablet 10 on the workbench 2! to be projected.

Next, place the original on the operating side? Entered using the numeric keypad or keyboard 21 provided on the 11ffi7 (
After S3), the magnification adjustment switch provided on the operation control panel 7 is operated to match the pattern of the original image (2) with the layout designation figure drawn on the layout designation sheet B. Note that the matching of the positions at this time is performed by shifting the layout designation paper B on the workbench 2.

After this, if the operation IIJ control panel 70 magnification display switch is operated, the magnification at that time is displayed on the magnification display 8, and the magnification data is taken into the arithmetic and control unit 20 (S
4).

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, various position data on the layout designation sheet B are input (S
6).

FIG. 4 is an explanatory diagram of input points on the data tablet 10. In FIG.
On the top, a plate line H forming a rectangle and a figure E for designating layout are drawn. The projected image I is projected so as to match the figure E.

First, 2 on the plate & ilH drawn on the layout designation paper B.
Input the position data of points P1 and R2 using the cursor 11. This printing plate line H corresponds to a reference line when pasting a document onto a disassembly drum of a scanner. Next, the vertices 1?1 of the rectangle forming the projected image I. Input the position data of R2, R3, and R4 using the cursor 11, and then input the rectangular vertices Q1, Q2, and
Input position data for Q3 and Q4 using the cursor 11.

These position data are taken into the arithmetic control unit W20 by operating the operation switch of the operation control panel 7 or the keyboard 21.

When the position data on the layout designation sheet B is input in this way,
At this point, the arithmetic control unit 22 starts processing the position data and the magnification data, calculates pasting line data and trimming range data of the original (S6), and stores them in the memory 23. Further, the inclination of this paste line with respect to the reference line, that is, the set angle data of the document F is simultaneously displayed on the angle display.

Next, the cursor 3 of the XY block 30 with digitizer

S7).

FIG. 6 is an explanatory diagram showing input of the output position in the XY plotter with digitizer 30. As shown in FIG. Outline showing pasting line &
161 and a trimming line 61 are drawn. The output position of the XY profiler 31 is input by moving the cursor 33 and indicating a desired position on the digitizer surface 32.
If this is specified with the cursor 33, a figure like figure A whose outline is a trimming line will be drawn by the ben 34 with R2 as the center.

Next, when the gauge output scale inch of the operation control panel 7 or the keyboard 21 is operated, the data from the memory is sent to the control circuit of the XY block 30.
The graphic output operation by the plotter 30 is started, and the hard copy is completed at the position where the original paste line and the graphic indicating the trimming range were input in step 7 (S8).

After this, when performing magnification measurement work for the next document, the process returns from step 9 to step 2 and the operations up to step 8 are performed. In this case, in the manual operation at the output position in step 7, a figure consisting of the outline and trimming lines of the document inputted up to the previous operation has been drawn on the sheet 60, so refer to this drawn figure. You can easily input the desired output position.

In this way, when the magnification measurement work etc. of a predetermined document is completed, or when there is no more space for drawing figures on the sheet 60 in step 8, the end operation is performed (S9), and the measurement work is completed. Become.

FIG. 5 is an explanatory diagram showing the positional relationship of each point manually input from data table head 0 in step 6. Based on the diagram, the calculation of the pasting line data and trimming range data of the original in step 7 is explained in detail. Explain.

Two points P1 on the printing plate vAH in the X-Y coordinates shown in the figure,
When the coordinates of P2 are PL (a, b) and P2 (c, d), the inclination θ of the plate 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 yw−xsinθ+ycosθ+2 Than this becomes.

Also, since sin θ and cos θ are expressed as from the 0 formula, the coordinates of an arbitrary point manually entered on the data tablet 10 in the will be replaced with the coordinate values of for example,
The X-Y coordinate values of point R1 are (XRI, YRI), X-Y
Let the coordinate values be (xRl, yRl). Similarly, all points R2-R4 and Q1 to Q4 are obtained in xy coordinates.

Next, drawing coordinate values for drawing in the XY block 30 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
, Dy), then it becomes.

Therefore, the drawing coordinate values to be drawn by the XY plotter 30 can be obtained from the formulas (1), (2), and (2).

FIG. 7 (+1) is an example of drawing on a transparent sheet 100. In FIG. 'h10
ON, a magnification value of 1100I is drawn. transparent sea H
A rectangular original pasting line 102 is drawn in the center of OO,
A rectangular trimming line 103 indicating a trimming range is drawn inside the original pasting line 102 .

FIG. 7 fbl is an example of drawing on an opaque sheet 200 such as paper. In this case, a reference line 201, a document Na20ON, a magnification value of 200va, and a rectangular document pasting line 202 are drawn in the same manner as the transparent sheet 100, but the trimming vA2
03 is drawn with each side of a rectangle extended to the outside of the original pasting line 202. This is because the opaque sheet 200 is cut out along the document pasting line 202, and then the document is placed in the cutout.

FIG. 8 is an explanatory diagram showing an example in which original pasting lines and trimming lines are drawn on an opaque sheet based on the output position data input in step 7. As shown in the figure, a reference line 301 is drawn at one end of the sheet, and the original pasting line 3 of each original is drawn.
02 and trimming line 303 are drawn at desired positions, and the original N is drawn near these original pasting lines and trimming lines.
f130ON and a magnification value of 300- are drawn.

Note that the document pasting sheet created with the device of the present invention is not only used for the purpose of improving the operating efficiency of a layout scanner, but also for the purpose of using it in a normal scanner that is not connected to a combination machine to improve its operation. Needless to say, efficiency can be improved.

(Effects of the Invention) As described above, in the present invention, when measuring the magnification of the original, the position data of the layout designation sheet B and the projected image of the original are input on the data tablet 10, and the output position on the original pasting sheet is determined. Since the instructions are given on the output device, it is possible to obtain a sheet on which the document pasting line and the trimming line indicating the trimming range are drawn at the same time, which greatly improves the efficiency of the work of pasting the document onto the input drum of the scanner. You can set the trimming range accurately without having to set the trimming range on the display, and you can efficiently layout the image on the layout scanner. Since document pasting lines and trimming lines are drawn without wasting space, magnification measurement work and scanner color separation work can be performed efficiently, and as a result, the operating efficiency of the layout scanner can be greatly improved. It has the effect of being able to do it.
