Original sticking line positions are commanded to display original sticking lines 311-316 on an XY plotter 300, and original sticking lines 311-316 are so controlled that they do not overlap, and thereafter, originals F1-F3 are stuck to complete a hard copy. This hard copy is inputted to the layout scanner to take in original images.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for creating a document angle gauge 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. 14 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 unit 160 includes the computer 16
The tablet left digitizer 17 consists of
0 consists of a cursor 171 and an input surface 172, and input surface 1
In 72, a mount area 173 and a menu area 174 are set. The scanner section 180 is composed of an input drum 181, an output drum 182, a linear encoder 183, a row encoder 184, and ink faces 185 and 186, and the ink faces 185 and 186 are connected to the computer 161. Note that the computer 16
1 is composed of 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 sheets, and other instructions. First, a document is pasted on the input drum 181 of the scanner unit 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 rotary 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 interface 185 and stored in the memory 162. Image data is imported from the original for an area slightly larger than the actual trimming area based on the layout designation sheet (not shown), and is later imported into the layout combiator (
(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 combinator. 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 user specifies the magnification ratio, plate color, dot %, etc. using the keyboard 16G.

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 placed 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 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.

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.
This invention has been proposed by the present applicant as the invention of No. 9-162108.

However, the above-mentioned device that outputs the angle gage of originals cannot draw original pasting lines for pasting multiple originals onto one sheet, and unlike a layout scanner, it is not possible to draw original pasting lines for pasting multiple originals onto a single sheet. For those that require image data to be captured, there has been a problem in that the image data of the document cannot be captured efficiently, and as a result, the layout scanner cannot be operated efficiently.

(Objective of the Invention) The present invention has been made in view of the above-mentioned points, and provides a device that simultaneously outputs the pasting lines of a manuscript to desired positions on a manuscript pasting sheet, and efficiently operates a leiaratosushiyana. The purpose is to

(Summary of the Invention) To achieve this object, the present invention forms document angle data by setting a document, projecting it onto a designated layout sheet, and rotating the document by an angle specified by the designated layout sheet. an input device for inputting a number corresponding to a specific one of the four sides of the document and the size of the document; an arithmetic control device that calculates document pasting line data based on input; an output position indicating device for instructing the output position of the document pasting line to be output on the sheet; and a calculation result of the arithmetic control device and the output. An apparatus for creating a document angle gauge for a scanner is provided, which includes an output device that outputs a document angle gauge on which document pasting lines are drawn in response to input from a position pointing device.

The magnification measuring device 1 is connected to a keyboard 21 and a display 22 for calculation;
It is connected to the. Note that B is a designated layout sheet, and ■ is a projected image of the document placed in the document holder 5.

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 B placed on the surface of the workbench 2 as the projection surface of the document image. A document placed in a document holder 5 is illuminated by a light source provided in a lamp house 6 through a suitable condenser lens, and a projected image of the image is produced. is projected onto the surface of the layout designation sheet 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 over 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 a transparent original is placed in the original holder 5 and its projected image l is matched with the figure drawn on the designated layout sheet B, the magnification will be automatically displayed on the magnification display 8 and the magnification can be measured. It can be terminated. Note that such an automatic magnification measuring machine is well known.

Figure 1θ is an enlarged view of the part centered on the document holder 5.
(a) shows the front view, and fbl shows the side view. The document holder 5 is a holding part with a U-shaped side surface provided in the condenser lens part 61 below the lamp house 6. 62 so that it can be inserted into and removed from it, and there are document scissors 51.62 inside.
It includes a rotary encoder 52 and the like, and has an adjustment knob 53 protruding from the outside.

FIG. 11 is a view showing the inside of the document holder 5, (al is a side sectional view, fbl is a view of a part of the interior seen from below, and FIG. 12 is an exploded perspective view of a part of the document holder. A ring-shaped rotating frame 54 equipped with a square hole 54b for inserting and holding the scissors 51 is rotatably held by the round hole 5b of the partition plate 5a of the original holder 5, and a ring-shaped rotating frame 54 is provided with a square hole 54b for inserting and holding the scissors 51. The formed gears 54a mesh with gears 53a attached to the shaft of the rotary encoder 52. Therefore, by rotating the knob 53, the rotating frame is rotated through the gears 53a and 54a. 54 rotates, and the rotation is further transmitted to the rotary encoder 52 via the gear 52a, and data representing the rotation angle of the rotation frame 54 is extracted as an electrical signal.

The document scissors 51 are made by joining two transparent plates made of glass plates, plastic plates, etc. with a hinge. A document such as a color film is sandwiched between the two, and the document scissors 51 are held in a flat state by being attached to the rotating frame 54. It works to hold it.

Therefore, the original is held in the original holder 5, and the original is placed in the first
As shown in the figure, place the image of the document on the holding part 62 at the bottom of the lamp house 6, and as explained in FIG.
By projecting the image onto the surface of the image I, the image I can be rotated to any angle by adjusting the knob 53, and the resulting angle can be input to the arithmetic and control unit 20 as an electrical signal.

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 is input to the arithmetic and control unit 20 via the signal human input section 15. At this time, the arithmetic and control unit 20 imports data and starts arithmetic processing using the numeric keypad, push button switches, keyboard 21, etc. provided on the operation control panel 7. Di? A drive signal is output to the XY plotter 30, a display signal is output to the angle display 9 and the magnification display 8, and the like.

Next, the operation of setting the magnification and angle of the document according to this embodiment will be explained.

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

First, set the layout designation paper B (or a copy thereof) on the workbench 2 (St), then set the original such as color film in the document holder 5 (S2), and then set the layout designation paper B (or a copy thereof) on the workbench 2. An image of the original is projected onto the surface of paper B.

Next, the document size and document size are input using the ten keys or keyboard 21 provided on the operation control panel 7 (S3). Note that since the document size is usually limited to several types, a number or the like set corresponding to the size may be input.

In this case, the document size corresponding to the set number etc. is stored in the memory 23 in advance. After this, the operation control panel 7
The user operates the magnification adjustment switch provided on the layout designation sheet B to match the design of the original image (2) with the layout designation figure drawn on the layout designation paper B. In this case, the position is changed by shifting the layout designation paper B on the workbench 2.

Next, when the magnification display switch on the operation control panel 7 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 (S4).
.

As already explained, the above operation is almost the same as in the case of a well-known magnification measuring machine, and the following operation is not necessary for documents that do not require angle adjustment.

When the pattern matches and the magnification is determined in this way, the angle data is manually input to the 7J1n control device 20 (S5
). In manually inputting this angle data, first, turn knob 5.
3 to rotate the image I, align the horizontal and vertical edges of the image I with the horizontal and vertical designated lines of the layout designation paper B, and in this state, turn the 159 angle setting switch on the operation control panel 7. The data given by the rotary encoder 52 at this time is taken into the arithmetic and control unit 20 as reference data.Next, the knob 53 is operated again to rotate the image I so that the data drawn on the layout designation sheet B is Match the pattern of the image ■ with the designated figure again. Then, in this state, the angle calculation switch on the operation control panel 7 is pressed to cause the data obtained by the rotary encoder 52 at this time to be taken into the arithmetic and control unit 20 as measured angle data. When the reference angle data and the measured angle data are input in this way, the arithmetic and control unit 20 starts processing these data at this point,
Rotation angle data representing the rotation angle of the document is calculated, displayed on the angle change display 2S9, and stored in the memory 23.

Next, one of the four sides of the rectangular document is selected as the 4 (II constant side), and the measurement side width set in advance for each of these four sides is input (S6). After this, the operation control panel 7 Alternatively, by operating the keyboard 21, the arithmetic and control unit 20 starts iI''A'ft processing, calculates document pasting line data (S7), and stores it in the memory 23.
The output value U of this document pasting line data in the XY four footer 30 is manually stored in the memory 23 via the arithmetic and control unit 20 (S8).

Here, the operation system m! When the gauge output switch 7 or the keyboard 21 is operated, data from the memory 23 is sent to the control circuit of the XY plotter 30.
The graphic output operation by the plotter 30 is started, and a hard copy with the original pasting line drawn at the specified position is completed (S
10).

After this, when performing the magnification measurement work for the next document, the process returns from step SIO to step S2, and the operations up to step SIO are performed. In this case, in inputting the output position in step S8, since the pasting line of the original inputted up to the previous operation has been drawn on the sheet set in the XY block 30, the drawn pasting line You can easily input the desired output position by referring to the line.

In this way, when a series of operations are completed by repeating the measurement operation of a predetermined document, or when
If there is no more space to draw pasting lines on the sheet set on the Y block 30, perform the end operation (S
10).

FIGS. 4 fa) and BL are explanatory diagrams showing the selection of the measuring side of the original and the corresponding method of drawing the pasting line in step S6 of FIG. 3. The original is usually rectangular,
The original is pasted using any of the four sides of the rectangle. Which of the four sides to choose depends mainly on workability.

Then, numbers are assigned to each side for this side selection. In the illustrated example, the top side of the document, that is, the top, is set as 1, and hereinafter, as shown in the same figure (al), the clockwise direction is set as 2.3.4.

The reference lines for measuring the angles of these sides 1 to 4 are 101, 102, 103, and 104, and the angles formed by each of sides 1 to 4 and each of the reference lines 101 to 104 are θ11, θ2, θ3, and 104, respectively. Let it be θ4. Reference line 10
1 to 104 are a reference line 101 with a reference angle of 0 degrees, 103 parallel to this, and 102 perpendicular to these reference lines 101 and 103.
．． It consists of 104. Therefore, angles θ2 and θ4 measured with respect to the reference lines 102 and 104 can be replaced with angles with respect to the reference line 101, for example. Based on this IVA
As shown in FIG. 10 (bl), the pasting line 201.
202, 203, 204 are determined.

FIG. 5 is a flowchart showing the details of the operation performed by the arithmetic and control unit 20 in step S7 of FIG.

First, an angle is calculated based on the angle data input in step S5 of FIG.
23). After that, using this orthogonal line, a line segment R connecting from the coordinate center (corresponding to the center point of the input document) to the intersection of the measurement side and the orthogonal line in the X-Y coordinates shown in Figure 6 (al)
Find R, and find the coordinate point P (X
O, YO) are determined as contact point coordinates (S24). Here, the contact point is the contact point of the drawn line with the circle as shown in FIG. In other words, contact seat + I P (XO, YO)
A line segment to be drawn is calculated based on the document size input in step S3 of FIG. is calculated (S26).

These coordinates are located at each end of a line that extends equally long along the measurement side with the contact point coordinate P (XO, YO) as the center, and is
PI(XI, Yl) in bl, and P2(X2
．． Y2). This is how the paste line was determined.

7, 8, and 9 show examples of output position input in step S8 of FIG. 3, and each side will be explained based on the figures.

FIG. 7 shows an example of displaying the pasting line data calculated in step S7 on the display 22 and inputting the output position. In the figure, 250 indicates the outer frame of the sheet set on the XY plotter 30. , FN is the original size, and Sl is the size of the sheet. As shown, display 2
An outer frame 250 is displayed on the display screen of No. 2, and the outer frame 250
A document pasting line 251 is displayed at a predetermined position in the lower right corner inside, the document 11hFN input in step S3 is displayed near the pasting line 251, and near the lower right outside of the outer frame 50. The sheet size SI is displayed.

The outer frame 250 is displayed by inputting the size of the sheet on which the original pasting line will be drawn when the layout designated paper is set in step S1. This is done by directly inputting the size itself, or by inputting preset numbers and symbols, or the target scanner and drum type. The input sheet size is then stored in the memory 23 via the arithmetic and control unit 20. Note that if you do not input the size itself, the output size corresponding to the input number etc. is stored in memory 2 in advance.
It is stored in 3. The pasting line 251 is displayed based on the original pasting line data calculated in step 7, and the point AO in the figure corresponds to the center of the original, and the position of this point AO is predetermined.

The pasting line 251 displayed on the display 22 in this manner can be moved arbitrarily within the outer frame 250 by operating a cursor movement key (not shown) provided on the keyboard 21. It has become.

Therefore, the output position input in step S8 is performed by moving the center position of the document to a desired position by operating the keyboard 21 together with the pasting line 251. For example, by moving the center position of the document to the point AI shown in FIG. 7, the pasting line 251 moves to the position shown by the broken line in the figure, and the output position input is completed. Note that the predetermined point AO is at the bottom right corner as shown.

It is not limited to this section and can be set arbitrarily.

In addition, since the document pasting line etc. whose output position has been inputted up to the previous operation is displayed on the display 22, when inputting the output position in step S8, the pasting line displayed with the point PO as the center of the document is displayed. The line can be moved to a desired position by referring to these display figures into which output position data has already been input.

Now, based on FIG. 8 1b+, step 9. The output position input in step S8 will be explained.

As shown in the figure, a sheet 260 is placed on the digitizer surface 42.
A document pasting line 261 with a point 81 as the center position of the document is drawn at the upper left corner of the screen 260. The output position in step S8 is input by moving the cursor 43 and pointing to a desired position on the digitizer surface 42.

For example, when the point 62 is designated with the cursor 33 as shown in the figure, a pasting line centered on the point B2 of the document will be drawn by the ben 44.

FIG. 9 shows an example of instructing a plurality of pre-stored output positions of the XY plotter 30, and FIG.

A document pasting line 261 centered on the document is drawn.

Here, the output position of the XY plotter 3o is input as follows. First, a transparent film 270 is placed on the sheet 260 on the board 31. Grid lines 273 are drawn on the transparent film 270, and intersection points 1 and 274 are attached to the intersections of the grid lines 273. This transparent film 270
The board 31 is positioned by fitting the 7L 271.271 provided at one end of the transparent film 270 into the pin 32.32 provided at one end of the board 31.

Next, a desired output position from the intersection Na 273, that is, an intersection near the document center point C2 of the pasting line to be drawn, is selected and input using the ten keys provided on the operation control mm7 or the keyboard 21.

This means that the output position has been input in step S8.
