Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for creating a document angle pasting gauge for a scanner.

(Prior Art) When performing color separation work on a reflective original using a scanner, the color original is attached to the scanning drum of the scanner. In this case, it is necessary to correctly set the color original on the scanning drum as specified on the layout designation sheet and input the magnification ratio.

Conventionally, this setting work has been performed manually by an operator based on visual measurements. In other words, the inclination angle of the figure drawn on the designated layout paper is measured with a protractor,
Based on this measured value, the angle of the document is confirmed using a protractor, etc., and the document is attached to the scanning drum. Regarding the magnification ratio, measure the distance between the two points of the figure drawn on the designated layout paper and the distance between the corresponding two points of the manuscript using a ruler, etc., and calculate the ratio of the two measured values. to find the magnification ratio and input it into the scanner.

In addition, for transparent originals, a device has been proposed that uses a magnification measuring device with an original projection function to measure the magnification ratio and output the original angle pasting gauge, and the above-mentioned work has been improved. .

(Problem to be Solved by the Invention) However, the magnification measuring device having the projection function as described above cannot be used for reflective originals.
The reality is that angles and magnification ratios are measured manually.

The present invention has been made in view of the above-mentioned points, and provides a device for creating a sheet-like gauge that indicates the position at which a document should be attached to a reflective document and the orientation that the document should take, and a device for calculating a magnification ratio. The purpose is to provide.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 2 is an external view of a device showing an embodiment of the present invention, in which 1 represents the document angle setting device for scanner, 2 is a workbench, 3 is a data tablet, 4 is a cursor, and 5 is an operation control panel. , 6 is a magnification indicator, and 7 is an angle indicator. In addition, represents the manuscript. The layout designation sheet and the original are set on the data tablet 3, and position data is input using the cursor 4. The main body 1 of the apparatus is connected to an XY blotter 30 via a computer 20 consisting of a main body 22 having a keyboard and a display.

FIG. 1 is a diagram showing an example of a signal processing system according to an embodiment of the present invention, in which data given from a data tablet 3 is input to an arithmetic control section 22 via a signal input section 10. However, at this time, the acquisition of data and the start of arithmetic processing by the arithmetic control unit 22 are controlled by a numeric keypad, push button switch, etc. provided on the operation control panel 5.
A display signal is outputted to the angle indicator 6, etc.

Next, the operation of determining the angle and calculating the magnification ratio according to this embodiment will be explained.

FIG. 3 shows the positions of the layout designation paper and the document inputted on the data tablet 3, and B is the layout designation paper.

First, place the layout designation sheet B (or a copy thereof) on the data tablet 3 attached to the workbench 2.
and operate the start switch on the operation control panel 5.

Next, as shown in Figure 3a, the layout designation sheet B
Input the position data of two points 1a and 1b of the figure drawn in , and two points 2a and 2b on the reference line L using the cursor 4. This is data for calculating the slope φ1 of the figure drawn on the layout designation sheet B with respect to the reference line L and the distance between the two points 1a and 1b. By doing so, the data is taken into the arithmetic control section 22.

After this, the original is set on the data tablet 3, and two points 3a and 3b on the original image and two points 4a and 4b on the reference line M are placed on the original as shown in FIG.
Input the position data using cursor 4. The two points 3a and 3b on the image of the manuscript are selected to correspond to the two points 1a and 1b of the figure drawn on the layout designation sheet B, and the reference line M is, for example, the outer edge of the manuscript. do. This is the slope φ2 of the image of the original with respect to the reference line L, and the two points 3a,
3b, and this data is taken into the arithmetic control section 22 by operating an operation switch provided on the operation control panel 5.

When the position data of the figure drawn on the layout designation sheet B and the image of the original are inputted in this way, the arithmetic control unit 22 starts processing these data at this point, and the set angle data and scaling factor data of the original are input. is calculated, displayed on the angle display 7 and magnification display 6, and stored in the memory 23. The angle data is obtained by taking the difference between φ1 and φ2 above, and the magnification ratio is 1a above,
It is calculated by taking the ratio of the distance between 1b and the distance between 3a and 3b.

Here, when the gauge output switch on the operation control panel 5 is operated, the data from the memory 23 is
is sent to the control circuit of the plotter 30, which causes
A graphic output operation by the XY plotter 30 is started, and a hard copy on which a predetermined angle indicating gauge graphic is drawn is completed.

FIGS. 7a and 7b show how to select the measurement side of a document and how to draw a pasting line accordingly. The original is usually rectangular, and 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 the numbers 2, 3, and 4 are set clockwise as shown in FIG. 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 θ1 and θ2, respectively. , θ3, θ4. Reference lines 101 to 104 are the reference line 101 with a reference angle of 0 degrees, 103 parallel to this, and these reference lines 101, 103.
It consists of 102 and 104 perpendicular to . Therefore, the angles θ2 and θ4 measured with respect to the reference lines 102 and 104
can be replaced with an angle with respect to the reference line 101, for example. This is set as an angle with respect to the reference line 100 set slightly above the reference line 101, and the pasting lines 201, 202, 20 as shown in FIG.
3,204 is determined.

FIG. 4 is a flowchart showing the operation of the apparatus shown in FIG. 1, which will be explained below.

First, key input is performed to select a format that specifies the imposition state of the original (S1). In this example, there are 5 formats available, and this is the No. 1 format.
to No. 5, and here, as shown in Figure 8, an A8 size document is placed in a rectangular area of 500 mm in width and 300 mm in height.
300 with 18 sides, 301 with 6 sides of B7 size original, 6 sides of A8 size original and 301 with 6 sides of A8 size original.
302 has 4 sides of a B7 size original, 303 has 2 sides of an A5 size original, and 304 has 1 side of an A5 size original. Here, 110 to 114 are reference lines on the angle gauge that correspond to the reference lines on the scanning drum, and 120
124 represents the original pasted along the pasting line. These formats are arbitrarily determined within the range of paper dimensions that can be drawn by the built-in plotter, and are stored in the memory 23 in advance.

Therefore, when any key from 1 to 5 is pressed (S2), any one of steps S3 to S7 is selected.

Since no termination operation is performed at this stage, the process passes through step S8 and performs the operations in steps S9 to S15. That is, a predetermined number for each document is inputted from the operation control panel 5 in FIG. 1 (S9), and then the layout designation sheet and document position data are inputted from the data tablet 3 (S11). , determine the measurement side number as explained in Fig. 7, input it through the operation control panel shown in Fig. 1 (S12), and set the output area during formatting.
Enter the number in the same way (S13).

Based on these inputs, the arithmetic control unit 22 in FIG. 1 calculates the drawing line, that is, the line including the paste line (S14),
Based on the input output area number, memory 2
The drawing parameters stored in step 3 are read out, and predetermined pasting lines, etc. are drawn at predetermined positions on the format using the XY plotter 30 (S15).

The operations of steps S9 to S15 are repeated for each original document, and pasting lines, etc. are drawn on each part of the formmat, and the original pasting gauge is completed.

Figure 5 shows the drawing line calculation step (S14) in Figure 4.
is shown in more detail.

First, step S21 leads to step S11 in FIG.
The angle is calculated based on the position data input in . Then, in step S22, convert to radians,
Next, a line perpendicular to the measurement side is determined (S23). After this, using this orthogonal line,
A line segment RR connecting from the coordinate center to the intersection of the measurement side and the orthogonal line is determined in the coordinates, and a coordinate point P (X0, Y0) at the opposite coordinate center end of this line segment RR is determined as the contact coordinate (S24). Here, the contact point is the contact point of the drawn line with the circle as shown in FIG. In other words, a drawn line segment is calculated based on the format and measurement side number with the contact point coordinates P (X0, Y0) as the center (S25), and the coordinates of both ends of the drawn line segment are calculated based on this line segment length (S25). . This coordinate is the contact point coordinate P(X0,
P1 (X1,
Y1), and P2(X2, Y2). This is how the paste line was determined.

Therefore, a calculation formula is selected depending on the format of the imposition, that is, whether the imposition is of the same size or includes impositions of different sizes. If the sizes are the same, calculation formula 1 is adopted as the first group (S28), if the sizes are different, calculation formula 1 is adopted as the first group (S28), and calculation formula 2 is used as the second group of different sizes. Adopt (S29). Then, the center coordinates of the drawing area are calculated (S30), the drawing parameters corresponding to the output area No. input in step S13 are read from the memory 23, and the output that has been translated in parallel to the drawing area specified by the read drawing parameters is Form (S31).

(Effects of the Invention) As described above, the present invention allows the angle and magnification of the original to be easily measured by inputting the layout designated paper and original position data into the data tablet.
This measurement value and the measurement side command entered separately,
Based on the output position command, it is possible to provide a document angle pasting gauge that draws a pasting line at a predetermined position in a predetermined format. Therefore, it is possible to greatly improve the efficiency of the work of pasting documents onto the scanning drum of the scanner.
