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.

(Prior art) When performing color separation work on a document using a scanner, first,
It is necessary to attach the document to the scanning drum of the scanner at the angle specified by the layout specification sheet, and then input the magnification ratio and trimming range.

Conventionally, pasting of the original is performed by an operator, and input of the magnification ratio and trimming range is performed based on visual measurements. In other words, when pasting a document, the angle of inclination of the figure drawn on the designated layout paper is measured with a protractor, and based on this measurement, the angle of the document is confirmed using a protractor, etc., and then the scanning drum is attached. It is pasted on. Regarding the magnification ratio, measure the distance between two points of the figure drawn on the designated layout paper and the distance between the two points of the document corresponding to these two points with a ruler, etc., and calculate the ratio of the two measured values. to find the magnification ratio and input it into the scanner. Regarding the trimming range, the operator inputs the trimming range into the scanner by visual measurement while comparing the trimming range drawn on the layout designation sheet with the original.

In addition, as an improvement to the above-mentioned work, a patent application filed in 1982 utilizes a magnification measuring machine with a function of projecting the original to measure the variable magnification and output the angle gauge of the original.
This invention has been proposed by the present applicant as the invention of No.-162108.

(Problems with the Prior Art) However, the device that outputs the angle gauge of the document described above cannot instruct the trimming range, and the actual situation is that the trimming range depends on the operator's visual estimation.

Therefore, the image range captured by the scanner according to the operator's instructions often deviates from the actually required image range. If the range captured by the scanner is smaller than the required range, it will have to be redone; if it is larger, it will waste time. However, there was a problem that the scanner could not be operated efficiently.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and provides an apparatus for efficiently operating a scanner by simultaneously outputting the variable magnification of the original, the pasting line of the original, and the l/rimming range. The purpose is to

(Summary of the Invention) In order to achieve this object, the present invention inserts a document into an optical system, projects an image of the document onto a designated layout sheet, and matches this projected image with a figure on the designated layout sheet. means for generating variable magnification data of a document; a data tablet for inputting position data of a reference line on the designated layout sheet and the projected image; and a data tablet for performing calculations based on the variable magnification data and the position data to perform document pasting lines and trimming. A document pasting sheet for a scanner, comprising arithmetic control means for outputting range data, and means for outputting a sheet I in which the pasting line and the trimming range are omitted according to the output of the arithmetic control means. It provides a creation device.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is an external view of an apparatus showing an embodiment of the present invention, in which 1 represents a magnification measuring device, 2 a work table, 3 a column, 4 a projection lens, 5 a document holder, 6 a lamp house, 7 is an operation control panel, 8 is a magnification display, 9 is an angle display, 10 is a data table left, and 11 is a cursor. The magnification measuring device 1 is connected to an XY plotter 30 via a computer 20 consisting of a main body 22 having a keyboard 21 and a display. In addition, B is the designated layout paper, and ■ is the document holder 5.
This is a projected image of the original set on the screen.

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. The document placed in the document holder 5 is illuminated by a light source provided in the lamp house 6 through a suitable condenser lens, and a projected image I 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. 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 B.

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 I is made to match the figure drawn on the designated layout paper 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 device is well known.

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 table O is sent to the arithmetic control section 22 via the signal input section 15. However, at this time, the arithmetic control unit 22 inputs data and starts arithmetic processing using the numeric keys and push button switches provided on the operation control panel 7 or the keyboard 21 provided on the computer 20. controlled by xy plotter 3
A drive signal for 0 is output, a display signal is output for 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, place a document F such as a color film in the document holder 5 (Sl), and place a specified layout sheet B (or a copy thereof) on the data tablet 10 on the workbench 2 (S1).
2) After that, project the image of the original onto the surface of the layout designated paper B.

Next, after inputting the original text using the numeric keys provided on the operation control panel 7 or the keyboard 21 provided on the computer 20 (S3),
The user operates a magnification adjustment switch provided on the layout designation sheet B to match the design of the original image I with the layout designation figure drawn on the layout designation paper B. Note that the matching of the positions at this time is performed by shifting the layout designation paper B on the workbench 2.

Thereafter, 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 control section 22 (S4).

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.

FIG. 4 is an explanatory diagram of input points on the datatable (Reso) 10. In the figure, a designated layout sheet B is placed R on a data tablet 10 provided on a workbench 2, and a designated layout sheet B
On the top, a plate line H forming a rectangle and a figure E for designating layout are drawn. The projected image (■) is projected so as to match the figure E.

First, two points P on the printing plate line H drawn on the layout designation paper B.
1. Input the position data of R2 using the cursor 11 (S
5). This plate surface &%H corresponds to the base tJ line when pasting a document on the decomposition drum of the scanner. Next, the vertices R1, R2, R3, and R of the rectangle forming the projected image ■
4 manually using the cursor 11 (S6), and further position data of vertices Q1, Q2, Q3, Q4 of the rectangle indicating the trimming range in the projected image (2) are input using the cursor 11 (S7). These position data are transmitted to the calculation control unit 22 by operating the operation switch on the operation control panel 7.
be taken in.

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 F (S8), 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.

Here, when the gauge output switch on the operation control panel 7 is operated, the data from the memory is sent to the control circuit of the XY block 30, which starts the graphic output operation by the XY processor 30, and the original pasting line A hard copy with a figure showing the trimming range is completed (S9
).

FIG. 5 is a diagram showing the positional relationship of the points on the data tab left 10, and the calculation of drawing data in S8 will be explained in detail based on the diagram.

Two points P1 and R on the printing plate line H at the X-Y coordinates shown in the figure.
If the coordinates of 2 are PL (a, b), R2 (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 green perpendicular 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=XCO8θ+y sinθ+W y=-xsinθ+ycosθ+2 Than this becomes.

Also, since sin θ and cos θ are expressed as from equation 0, the coordinates of an arbitrary point input in the X-Y coordinates on the data tablet 10 are will be replaced with the coordinate values of for example,
The X-Y coordinate values of point R1 are (XRI, YRI), X-y
When the coordinate values are (xRl, yRl), it becomes c-al. Similarly, all points R2-R4 and mouths 1-Q4 are obtained in x-y coordinates.

Next, drawing coordinate values for drawing with the XY plotter 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 (D
x, Dy), then

Therefore, from ■, ■, 0 formula, XY Pro 7ri 3oT:
t=The drawing coordinate value to be drawn will be obtained.

FIG. 6 (al, fbl, FC+ are explanatory diagrams showing examples of original pasting lines and trimming lines drawn based on the drawing data calculated as described above.

FIG. 6 (al is an example drawn on a transparent sheet 100).

In the figure, a base lJ line 101 corresponding to the printing plate line H is drawn on an example of a transparent sheet 100, and an original 1kioO
N and a magnification value of 100 m are drawn. Transparent sheet 10
A rectangular original pasting line 102 is drawn in the center of 0, and a rectangular trimming line 103 indicating the l/rimming range is drawn inside the original pasting line 102.

FIG. 6 (bl is an example of drawing on an opaque sheet 1-200 such as paper. In this case, like the transparent sheet 100 above, the reference line 201, original 1'h20ON, magnification value 200m, rectangular original pasting line 202 is drawn, but the trimming line 2
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 and cut out along the document pasting line 202, and then the document is set in the cutout portion.

FIG. 6(C) is an example of drawing on a sheet 300 in which multiple manuscripts are pasted onto one sheet.

In this case, coordinate movement parameters are set in advance, and by inputting the output position floor, the drawing coordinates including the coordinate movement parameters are calculated, and the reference line 301 is set at a predetermined position, the document barrier 30 is ON, and the magnification value is 30f)+n. , manuscript pasting line 302
, a trimming line 303 is drawn.

5. Effects of the Invention) As described above, the present invention allows the document pasting line and the trimming range to be determined by inputting the position data of the layout designation sheet B and the projected image (■) of the document on the data table press 0 when measuring the magnification of the document. The trimming lines shown are drawn at the same time, which greatly improves the efficiency of pasting documents onto the scanner's scanning drum, and allows accurate setting of the trimming range, resulting in a significant improvement in scanner operating efficiency. This effect will be achieved.
