Description

TECHNICAL FIELD The present invention relates to a device for manufacturing an original angle sticking gauge for a scanner.

(Prior Art) When performing color separation work on a reflective original using a scanner, a color original is attached to a scanning drum of the scanner. In this case, it is necessary to correctly set the color original on the scanning drum as specified by the layout-designating paper and input the scaling factor.

This setting work is conventionally performed manually by an operator based on visual inspection. That is, the inclination angle of the figure drawn on the layout-designated paper is measured by a protractor, and the original is attached to the scanning drum while confirming the angle of the original using the protractor or the like based on the measured value. Regarding the scaling factor, measure the distance between two points of the figure drawn on the specified sheet and the distance between the two points of the original document corresponding to these two points with a ruler, etc., and calculate the ratio of the two measured values. The scaling factor is calculated and input to the scanner.

Further, for a transparent original, there has been proposed an apparatus for measuring a variable magnification and outputting an angle sticking gauge of the original by using a magnification measuring apparatus having an original projection function. An apparatus for measuring the magnification and angle of a document using a digitizer has been proposed, and the above work has been improved.

(Problems of the prior art) However, a document using a magnification measuring device having a projection function cannot be used for a reflective document, and a document using a digitizer cannot be used for a transparent document, and therefore cannot be used. In contrast, the actual situation is that the angle and the scaling factor are manually measured.

(Object of the Invention) The present invention has been made in view of the above points, and is an apparatus for creating a sheet-like gauge that indicates a position to which a document is to be attached to a transparent document and a reflection document, and a posture that the document should take. Another object of the present invention is to provide a device for calculating a scaling factor.

(Summary of the Invention) To achieve this object, according to the present invention, a means for forming a document angle signal by setting a document and rotating the document at an angle designated by a layout designation sheet, and a document and a layout designation sheet are provided. 2 of the figures drawn on the specified layout paper after setting

For a scanner provided with arithmetic control means for performing calculation based on an output of angle data of a manuscript sticking line, and means for outputting an angle sticking gauge in which the sticking line is drawn according to the output of the arithmetic control means. An object of the present invention is to provide a device for creating a manuscript angle sticking gauge.

The projection lens 4, the document holder 5, and the lamp house 6 are integrally held by the column 3, and the magnification is such that the surface of the designated allocation sheet B placed on the surface of the workbench 2 is the projection surface of the image of the transparent document. The transparent original mounted on the original holder 5 is illuminated by a light source provided in the lamp house 6 through a suitable condenser lens or the like, and a projected image I of the pattern is formed. It is designed to be projected on the surface of the designated allocation sheet B.

Further, the projection lens 4, the document holder 5, and the lamp house 6 are configured to be movable up and down along the support column 3, and are moved up and down by operating a switch of the operation control panel 7 to thereby move the transparent document. The projected image I, which is obtained by reducing or enlarging the image to an arbitrary size over a predetermined range, is assigned to the designated paper B
The image can be formed on the surface of the. At this time, the distance between the projection lens 4 and the designated paper B for layout is taken in by a linear encoder or the like, arithmetic processing is performed to obtain the magnification, and the magnification is displayed on the magnification display 8.

Therefore, if the transparent original is set on the original holder 5 and the projected image I is made to match the figure drawn on the designated allocation sheet B, the magnification is automatically displayed on the magnification display 8 to measure the magnification. Can be terminated. Incidentally, such an automatic magnification measuring machine is well known.

FIG. 6 is an enlarged view of a portion centering on the document holder 5, in which FIG. 6A shows the front surface and FIG. 6B shows the side surface, and the document holder 5 is located below the lamp house 6. It is designed to be held so that it can be inserted into and removed from a holding portion 62 having a U-shaped side surface provided on the condenser lens portion 61.

Can be rotated to an arbitrary angle, and the angle at that time can be taken in as an electric signal in an external arithmetic control unit.

FIG. 2 is a diagram showing an example of a signal processing system in one embodiment of the present invention, in which data given from the rotary encoder 52 and the data tablet 10 is inputted to the arithmetic control unit 22 via the signal input unit 15. However, at this time, the operation control unit 22 captures data, starts arithmetic processing, etc.
Controlled by the ten-key pad or push-button switch provided on the operation control panel 7 or the keyboard 21 provided on the computer 20, the drive signal output to the XY plotter 30 and the display signal output to the angle display 9 are performed. Done.

Next, the operation of adjusting the magnification and the angle of the original according to this embodiment will be described.

First, the following operation is performed on the transparent original.

Designated paper B for layout on the data tablet 10 on the workbench 2
(Or a copy thereof) is placed, and in parallel with this, an original F such as a color film is set on the original holder 5 and an image I of the original is projected on the surface of the designated allocation sheet B.

The magnification adjustment switch provided on the operation control panel 7 is operated so that the pattern of the original image I matches the pattern for layout designation drawn on the layout designation paper B. The matching of the positions at this time is performed by shifting the layout-designating sheet B on the workbench 2.

When the operation of is finished, if the magnification display switch of the operation control panel 7 is operated, the magnification at that time is displayed on the magnification display 8.

As already explained, this operation is almost the same as that of the known magnification measuring machine, and therefore,
The following operations are not required for documents that do not need to be angled.

When the matching of the patterns is obtained and the magnification is obtained, the knob 53 is then operated to rotate the image I, so that the layout designated paper B is leveled,
The horizontal and vertical edges of the image I are aligned with the vertical designation line, and the reference angle setting switch of the operation control panel 7 is pressed in this state, and the data given by the rotary encoder 52 at this time is used as reference data for arithmetic control. Incorporate into Part 22.

Again, the knob 53 is operated to rotate the image I, and the design of the image I is matched again with the designated graphic drawn on the designated layout paper B. Then, in this state, press the angle calculation switch of the operation control panel 7, and the rotary encoder at this time
The data obtained by 52 is taken into the calculation control unit 22 as measurement angle data.

In this way, when the reference angle data and the measurement angle data are input subsequently, the arithmetic control unit 22 starts the processing of these data at this time, calculates the rotation angle data representing the rotation angle of the document, and calculates it. The angle is displayed on the angle display 9 and stored in the memory.

Here, when the gauge output switch of the operation control panel 7 is operated, the data from the above memory is sent to the control circuit of the XY plotter 30, whereby the figure output operation by the XY plotter 30 is started, and the predetermined angle indication gauge figure is displayed. A hard copy with is drawn.

Next, the operation of adjusting the magnification and angle of the reflection original will be described.

FIG. 9 shows the positions of the designated allocation sheet B and the original E input on the data tablet 10.

First, the data tablet attached to the workbench 2
Set the designated allocation paper B (or its copy) on top of 10,
The start switch of the operation control panel 7 is operated.

Next, as shown in FIG. 9 (a), two points 1a and 1b of the figure drawn on the designated allocation sheet B and two points on the reference line L are drawn.
The position data of the points 2a and 2b is input with the cursor 11. This is data for calculating the inclination φ1 of the figure drawn on the layout-designating paper B with respect to the reference line L and the distance between the two points 1a and 1b. This data is obtained by operating the operation switch provided on the operation control panel 7. It is taken into the arithmetic control unit 22 by being operated.

After this, the original E is set on the data tablet 10 and, as shown in FIG.
The position data of a, 3b and two points 4a, 4b on the reference line M are input with the cursor 11. For the two points 3a and 3b on the image of the original E, the points corresponding to the two points 1a and 1b of the figure drawn on the designated allocation sheet B are selected, and the reference line M selects the outer edge of the original E, for example. I shall. This is data for calculating the inclination φ2 of the image of the document E with respect to the reference line L and the distance between the two points 3a and 3b. This data is arithmetically controlled by operating the operation switch provided on the operation control panel 7. Part 22
Is taken into.

When the position data of the figure drawn on the layout-designating paper B and the image of the document E is input in this way, the arithmetic control unit 22 starts processing of these data at this point, and the set angle data of the document E and the change of the data are obtained. The magnification data is calculated and displayed on the angle display 9 and the magnification display 8 and stored in the memory 23. By taking the difference between φ1 and φ2 above for angle data, the scaling factor is the distance between 1a and 1b above and 3a and 3b
It is calculated by taking the ratio of the distances between them.

Here, when the gauge output switch of the operation control panel 7 is operated, the data from the memory 23 is sent to the control circuit of the XY plotter 30, whereby the graphic output operation by the XY plotter 30 is started, and the predetermined angle indicating gauge graphic A hard copy with is drawn.

FIGS. 10 (a) and 10 (b) show how to select the measurement side of the original and how to draw the sticking line accordingly. The original is usually rectangular, and the original is pasted using any of the four sides forming the rectangle. Which of the four sides is selected depends mainly on workability. Then, each side is numbered for this side selection. In the illustrated example, the top side of the document, that is, the top, is set to 1, and as shown in FIG. Reference lines 101, 102, 103, and 104 are used to measure the angles of the sides 1 to 4, and the angles formed by the sides 1 to 4 and the reference lines 101 to 104 are θ1 and θ, respectively.
2, θ3 and θ4. The reference lines 101 to 104 include a reference line 101 having a reference angle of 0 degree, 103 parallel to the reference line 101, and 102 and 104 perpendicular to the reference lines 101 and 103. Therefore, the angles θ2 and θ4 measured with respect to the reference lines 102 and 104 can be replaced with, for example, the angles with respect to the reference line 101. This is the reference line 101
As shown in FIG. 10 (b), the sticking lines 201, 202, 203, 204 are set as angles with respect to the reference line 100 set slightly above.
To decide.

FIG. 3 shows the operation contents of the apparatus of FIG. 1 as a flowchart, which will be described below.

First, the program is started by the keyboard 21 of the computer 20, and then the key input for selecting the format is performed (S1). In this example, 5 types of formats are prepared, and there are No. 1 to No. 5.

This format is, for example, horizontal 50 as shown in Fig. 11.
0mm, 300mm length rectangular area with 35mm film 18 sides
300, 6cm x 6cm film with 6 faces 301, 35mm film with 6 faces and 6cm x 6cm film with 4 faces 302, 4in x 5in film with 2 faces 303, 4in
304 with 1 x 5in film.

Here, 110 to 114 are reference lines on the angle sticking gauge corresponding to the reference line on the scanning drum, and 120 to 124 are originals stuck according to the sticking lines. These formats are arbitrarily determined within the range of the size of the paper that can be drawn by the built-in plotter.

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

At this stage, the ending operation is not performed, so that the operation proceeds from step S8 to steps S9 to S17. That is, the No. that is predetermined for each manuscript is the first
Input is made from the operation control panel 7 shown in the figure (S9), and then the type of document is input (S10).

In the case of a transparent original, the measured magnification value is input from the operation control panel 7 (S11), and an angular pulse is input from the rotary encoder 52 of the original holder 5 in the apparatus shown in FIG. 1 (S1).
2). In the case of a reflection original, the designated sheet of layout and the position data of the original are input from the data tablet 10 (S13).

After this, as described with reference to FIG. 10, the measurement side No. is determined, and this is input by the operation control panel 7 of FIG. 1 (S1
4) Also, input the output area number in the format in the same way (S15).

Based on these inputs, the arithmetic control unit 22 of FIG. 1 calculates a drawing line, that is, a line including a pasting line (S16), and the XY plotter 30
Draw a predetermined sticking line or the like at a predetermined position of the format by (S17).

The operation of steps S9 to S17 is repeated for each original document, and a sticking line or the like is drawn on each part of the format to complete the original sticking gauge.

FIG. 4 shows the drawing line calculation step (S17) of FIG. 3 in more detail.

First, in step S31, the angle calculation is performed based on the angle pulse input in step S17 of FIG. 3 or the position data input in step S18. Then, in step S32, radian conversion is performed, and then a line orthogonal to the measurement side is obtained (S33). After this, using this orthogonal line, FIG. 5 (a)
In the XY coordinates shown in Fig. 5, a line segment RR connecting from the coordinate center to the intersection of the measurement side and the orthogonal line is obtained, and the coordinate point P (X0, Y0) at the end of the anti-coordinate center of this line segment RR is obtained as the contact coordinates (S3
Four). Here, the contact point is the contact point of the drawing line with respect to the circle as shown in FIG. That is, the contact point coordinate P (X0, Y
The drawing line segment is calculated based on the format and the measurement side number centering on (0) (S35), and the coordinates of both ends of the drawing line segment are calculated based on this line segment length (S36). These coordinates are located at each end of a line that extends in equal length along the measurement side with the contact point coordinate P (X0, Y0) as the center, and P1 (X1, Y in FIG. 5B).
1) and P2 (X2, Y2). This is the reason why the sticking line was decided.

Therefore, the calculation formula is selected depending on what format the imposition is, that is, whether the imposition has the same size or different sizes are included. If the sizes are the same, the calculation formula 1 is adopted as the first group (S38). If the sizes are different, the calculation formula 1 is adopted as the first group (S38), and then the second group having the different sizes is calculated. Formula 2 is adopted (S3
9). Then, the center coordinates of the drawing area are calculated (S40), and the parallel translated output to the drawing area is formed (S41).

(Effect of the Invention) As described above, according to the present invention, for a transparent original, by setting the original on the original holder and matching the projected image with the figure on the designated layout paper, the reflection original is also reflected. Is
By inputting the position data of two points of the figure drawn on the layout designated paper and the position data of the two points of the original image corresponding to the two points of the figure drawn on the layout designated paper with the data tablet, The angle of the document is calculated, and based on the calculated value, it is possible to provide a document angle sticking gauge in which a sticking line is drawn. Therefore, it is possible to significantly improve the efficiency of the operation of pasting the original on the scanning drum of the scanner.
