Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention relates to a document pasting sheet for a scanner, which is used when pasting a document onto a disassembly drum of a scanner. [0002]

[Conventional technology]

When performing color separation work on a document using a scanner, first,
It is necessary to attach the document to the separation drum of the scanner at the angle specified by the layout specification sheet, and then input the magnification ratio and cropping range. [0003] Conventionally, the pasting of the original is performed by an operator, and input of the magnification ratio and trimming range is performed based on visual estimation. In other words, when pasting a manuscript, use a protractor to measure the inclination angle of the figure drawn on the designated layout paper, and then use a protractor to check the angle of the manuscript based on this measurement value before placing it on the disassembly drum. It's pasted. 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 compares the trimming range drawn on the layout designation sheet with the original and visually inputs the trimming range into the scanner. [0004] Furthermore, as an improvement to the above-mentioned work, a device was disclosed in Japanese Patent Application Laid-Open No. 1983-1980 that uses a magnification measuring machine having 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.-112039. [0005]

[Problem to be solved by the invention]

However, the sheet obtained from the above-mentioned document angle gauge output device cannot indicate the trimming range of the document, 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, and if the range captured by the scanner is smaller than the required range, it will have to be redone, and if it is larger, the capture time will be wasted. This has caused the problem that the scanner cannot be operated efficiently. [0006] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a sheet for efficiently operating a scanner, on which the variable magnification of the original, the pasting line of the original, and the trimming range are drawn at the same time. purpose. [0007]

[Means to solve the problem]

In order to achieve this objective, the present invention provides a document pasting sheet for a scanner, on which a document pasting line for pasting a document on the disassembly drum of the scanner, a trimming line indicating the capture range of the scanner, and a variable magnification are drawn at the same time. provide. [0008]

[Effect]

In the present invention, the original pasting line for pasting the original onto the disassembly drum of the scanner, the trimming line and magnification ratio indicating the capture range of the scanner are simultaneously drawn on the sheet, and the original is drawn along the original pasting line. is pasted on the sheet, and the sheet with this original pasted is set on the disassembly drum of the scanner, and the above-mentioned trimming [0009]

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view showing an example of a document pasting sheet for a scanner according to the present invention, on which document pasting lines, trimming lines, etc. are drawn. FIG. 1A shows an example in which original pasting lines, trimming lines, and the like are drawn on a transparent sheet 100. As shown in the figure, on one side of the transparent sheet 100, there is a reference line 101 that serves as a reference when setting the sheet 100 on the disassembly drum of the scanner.

2, a rectangular trimming line 103 indicating the trimming range is drawn. [0010] FIG. 1(b) is an example in which original pasting lines, trimming lines, etc. are drawn on an opaque sheet 200 such as paper. In this case, similarly to the transparent sheet 100, a reference line 201, original number 20ON, magnification ratio 200m, and a rectangular original pasting line 2O2 are drawn. It is drawn in an extended form to the outside of 2O2. This means that the opaque sheet 200 has the original pasting line 20.
After the document is cut along the cutout section 2, the document is set in the cutout section. [0011] In (C) of FIG. 1, the original pasting line, trimming line, etc.
Sheet 3 is for multi-sided printing where many originals are pasted on one sheet.
This is an example of drawing at 00. As shown in the figure, a reference line 301 is drawn on the sheet 300, and the document No. 3 of each document is drawn on the sheet 300.
0ON, a variable magnification of 300 m, a document pasting line 302, and a trimming line 303 are drawn at predetermined positions. [0012] Next, an apparatus for creating the sheet shown in FIG. 1 will be described. FIG. 2 is an external view of the apparatus for creating the original pasting sheet for the scanner shown in FIG. 6 is a lamp house, 7 is an operation control panel, 8 is a magnification display, 9 is an angle display, 10 is a data tablet, 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. Note that B is a designated layout sheet, and ■ is a projected image of the original set in the original holder 5. [0013] The projection lens 4, document holder 5, and lamp house 6 are integrally held by the support 3, and the surface of the layout designation paper B placed on the surface of the workbench 2 is used as the projection surface of the image of the document. 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 obtained. ■ 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. A projected image (2) obtained by reducing or enlarging the image 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 ratio is determined by arithmetic processing and displayed on the magnification display 8. Therefore, if you set a transparent original in the original holder 5 and match its projected image ■ with the figure drawn on the designated layout sheet B, the magnification change will be automatically displayed on the magnification display 8, and the magnification will be measured. can be terminated. Note that such an automatic magnification measuring device is well known. [0014] FIG. 3 is a block diagram showing an example of a signal processing system in the apparatus shown in FIG. However, at this time, the arithmetic control unit 22 takes in data and starts arithmetic processing using the numeric keypad or push button switches provided on the operation control panel 7 or the keyboard 21 provided on the computer 20. controlled by the XY plotter 30
A drive signal is output to the angle display 9 and a display signal is output to the magnification display 8. [0015] Next, the operation of setting the magnification, angle, and trimming range of a document by the apparatus shown in FIG. 2 will be described. FIG. 4 is a flowchart showing the measurement procedure in the above operation. First, set the document F such as a color film in the document holder 5 (S1). After placing the designated layout paper B (or its copy) on the data tablet 10 on the workbench 2 (S2), Image of manuscript on the surface■
to be projected. Next, after inputting the document number using the numeric keypad provided on the operation control panel 7 or the keyboard 21 provided on the computer 20 (S3), the user operates the magnification adjustment switch provided on the operation control panel 7, The pattern of the original image ■ is made to match 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, by operating the magnification display switch on the operation control panel 7, the current magnification is displayed on the magnification display 8, and the magnification data is taken into the arithmetic control unit 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. [0016] FIG. 5 is an explanatory diagram of input points on the data tablet 10. In the figure, a layout designation sheet B is placed on a data tablet 10 provided on a workbench 2, and on the layout designation sheet B are a plate line H forming a rectangle and a figure E for layout designation.
is depicted. 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 printing plate line H is the reference line 101.2 shown in FIG.
01.301, and serves as a standard for attaching documents to the disassembly drum of a scanner. Next, use the cursor 11 to input the position data of the vertices R1, R2, R3, and R4 of the rectangle that forms the projected image (S6).
2, O3, and O4 position data are input using the cursor 11 (S7). These position data are taken into the arithmetic system 9 section 22 by operating the operation switches on the operation control panel 7. [0017] 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, and stores them in the memory 23 (S8). 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 plotter 30, thereby starting the graphic output operation by the XY plotter 30, as shown in FIG. A scanner document pasting sheet on which original pasting lines, trimming lines, etc. are drawn is created (S9). [0018] FIG. 5 is a diagram showing the positional relationship of the respective points on the data tablet 10, and the calculation of drawing data in S8 will be explained in detail based on the diagram. Two points P1, P on the printing plate line H in the X-Y coordinates shown in the figure
If the coordinates of O are PL (a, b) and PO (cd), the inclination θ of the printing plate line H with respect to the coordinate axis X is tanθ= (d−
b)/ (C-a) ■. Here, if the origin is PO (w, z) and the new coordinates whose coordinate axes are the plane line H and the line 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 = x cos θ + y sin θ + W y = -x sin θ + y cos θ + 2 From this, x = (X-w) cos θ + (z - Y) sin θ
V = (X W) sin θ + (Y-z) cos θ
■It becomes. Moreover, sin θ and COS θ are expressed as follows from equation (2). [0019]

[Equation 1] d [00201 Therefore, the coordinates of any point entered in the X-Y coordinates on the data tablet) 10 are replaced by the coordinate values on the x-y coordinates with the printing surface line H as the reference from formulas ■ and ■. be done. For example, point R
Letting the x-y coordinate values of 1 be (XRI, YRI) and the x-y coordinate values of 1 (xRl, yRl), the following will be obtained. [00February

[Math. 2] c-at d-bl [Similarly, all points of R2-R4, 01 to Q4 are x
-y coordinate will be obtained. Next, drawing coordinate values for drawing with the XY plotter 30 are calculated from these coordinate values. If 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 values are (Dx, DY), then Dx=(17m)x Dy=( 1/m)y ■. Therefore, the drawing coordinate values to be drawn by the XY plotter 30 can be obtained from the formulas (1), (2), and (2), and the drawing coordinate values for the sheet 100 shown in FIG.
200.300 can be created. [0023] As shown in FIG. 1(C), when drawing multiple manuscript pasting lines, trimming lines, etc. on one sheet, the manuscript pasting lines, etc. of each manuscript may overlap and be drawn. In order to prevent this from happening, coordinate movement parameters are set in advance in the calculation control unit 22. Then, when the position data on the data tablet 10 is input manually, etc., by inputting an output position number that instructs the drawing area of each document pasting line, etc., the arithmetic control unit 22 draws a drawing including the coordinate movement parameters described above. Calculate the coordinate values, and use the XY plotter 30 to place the document No. 30ON, magnification value 30 axis, document pasting line 3O2 at a predetermined position.
, a trimming line 303 is drawn. [0024] The scanner document pasting sheet created in this manner is used when color separation of a document is performed by a scanner. First, the original is pasted onto the sheet along the original pasting line drawn on the sheet. This eliminates the need to set the angle at which the document is pasted on the disassembly drum of the scanner. Next, the sheet with the original pasted thereon is set on the decomposition drum so that the reference line drawn thereon matches the reference line on the decomposition drum of the scanner. After that, color separation of the original is performed by specifying the capture range of the scanner based on the trimming line drawn on the sheet, and specifying the separation magnification of the scanner based on the variable magnification drawn on the sheet. In this case, in order to efficiently perform the magnification measurement and position data input work in the device shown in Figure 2, or the color separation work in the scanner, multiple It is desirable to create something that can be pasted with original manuscripts. [0025] Effects of the Invention As described above, in the present invention, the original pasting line for pasting the original onto the disassembly drum of the scanner, the trimming line indicating the capture range of the scanner, and the variable magnification are simultaneously drawn on the sheet. The original is pasted onto the sheet along the original pasting line, and the sheet with the pasted original can be set on the scanner's disassembly drum, eliminating the troublesome angle of the original on the scanner's disassembling drum. Settings are no longer required, and the scanner's capture range and decomposition magnification can be accurately set based on the trimming lines drawn on the sheet and the magnification ratio, resulting in a significant improvement in scanner operating efficiency. It has the effect of being able to do it.
