JPS61156257A - Implementing device of original angle sticking gauge for scanner - Google Patents

Abstract

PURPOSE:To make sticking works to a scanning drum sharply efficient, by inputting an original angle signal, number to a prescribed position of a format, etc., in an arithmetic control section and outputting an original angle sticking gauge in which a sticking line is drawn. CONSTITUTION:When color separating operations are performed to an original by using a scanner, it is necessary to properly set the colored original against a scanning drum. Therefore, the original is set to a holder 5 and the graphic of an allocation designating paper B is made coincident with an image I by operating a knob, and then, the rotated angle when they coincide with each other is inputted in an arithmetic control section 12. In addition, the number corresponding to a specific side of the original out of the four sides and another number corresponding to a specific position of a format are inputted. The arithmetic control section 12 outputs an original sticking gauge in which sticking lines 201-204 are drawn from these input through an X-Y plotter 9. Therefore, original sticking works to the scanning drum of the scanner can be made sharply efficient.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an apparatus for producing a document angle pasting gauge for a scanner.

[Technical background]

When performing color separation work on a document using a scanner, the color document 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 by the layout designation sheet.

Conventionally, this setting work has been done manually by an operator based on visual measurements. In other words, measure the inclination angle of the figure drawn on the designated layout paper using a protractor, etc., and based on this measurement value,
The original is attached to the scanning drum while checking the angle of the original using a protractor or the like.

However, such work is not only inefficient but also inaccurate. Therefore, it may be possible to attach the original to the scanning drum of the scanner using some kind of auxiliary means.
As one of these methods, it has been considered to paste the original onto a sheet I-shaped gauge that is similar to the surface of the scanning drum of a scanner.

(Object of the Invention) The present invention has been made in consideration of the above-mentioned points, and provides an apparatus for creating a sheet-like gauge that indicates the position at which a document should be pasted and pulled, and the posture that the document should take. The porpose is to do.

[Summary of the invention]

In order to achieve this objective, the present invention provides a means for forming a pulse signal corresponding to the slope erasing of the original, a side number assigned in advance to indicate which side of the original was measured, and a side number indicating which side of the original was measured.
A means for inputting a predetermined output position @ number as to where to paste the original on the shape gauge, and one of several predetermined formats based on the input contents for both of the above means. Select one, roughly calculate the length and coordinates of the line segment to be drawn, and paste the manuscript according to the calculation results. The present invention provides an apparatus for producing an angle gauge.

〔Example〕

A detailed description of the present invention will be given below with reference to the accompanying drawings.

FIG. 4 is an external view of an embodiment of the present invention, in which 1 represents the entire document corner mark setting device for scanner, 2 is a workbench, and 3 is an external view of an embodiment of the present invention.
is a column, 4 is a projection lens, 5 is a document holder, 6 is a lamp house, 7 is an operation control panel, 8 is a magnification display, 9 is an X-Y
Plotter 10 is an angle indicator. Note that B represents a designated layout sheet, and ■ represents a projected image of the original.

The workbench 2 has the layout designation paper B placed on its surface to efficiently carry out magnification measurement work, etc., and also functions as a stand for the entire apparatus.

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 machine is configured such that the document holder 5
The original placed in the lamp house 6 is illuminated by a light source provided in the lamp house 6 through a suitable condenser lens, etc.
A projected image (■) of the picture is projected onto the surface of the designated layout paper B. Also, a projection lens 4, a document holding section 5
, and the lamp house 6 is 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, thereby allowing the image of the document to be adjusted to any size within a predetermined range. Projection image r reduced and enlarged to
can be imaged on the surface of the layout designation paper B. Then, the distance between the projection lens 3 and the designated layout paper B and the distance between the document and the like at this time are captured by a linear encoder, etc., and processed to calculate the magnification.
It is designed to be displayed on the magnification display 8.

Therefore, if you set the original, make its projected image (■) on the surface of the block base B, and match it with the figure drawn on the layout designation sheet B, the magnification will be automatically displayed on the magnification display 8. obtained, and the magnification measurement can be completed. Indeed, such automatic magnification measurement machines are well known.

FIG. 5 is an enlarged view of the central part of the document boulder 5, in which (a) shows the front and (b) shows the side. The document holder 5 is located below the lamp house 6. It is designed to be inserted into and removed from a holding part 62 provided in a condenser lens part 61 and having a U-shaped side surface, and a document clipper 51. It includes a rotary encoder 52 and the like, and has an adjustment knob 53 protruding from the outside.

FIG. 6 is a view showing the inside of the document holder 5, (a) is a side sectional view, (b) is a view of a part of the inside seen from below, and FIG. 7 is an exploded perspective view of the part. A ring-shaped rotating frame 54 equipped with a square hole 54b for inserting and holding the document scissors 51 is inserted into the round hole 5b of the partition plate 5a of the document holder 5.
The gear parts 54a formed on the lower outer periphery of the D-tariender 52 mesh with the gears 53a attached to the shaft of the D-tariender 52, respectively. Therefore, when the knob 53 is rotated, the rotating frame 54 is rotated via the gear 53a and the gear portion 54a, and the rotation is further transmitted to the rotary encoder 52 via the gear 52a. Data representing the rotation angle of 54 will be extracted as an electrical signal.

The document scissors 51 are made by connecting two transparent plates made of glass plates, plastic plates, etc. with a hinge, and hold the document F such as a color film between them, and hold the document F in a flat state using a rotating frame 54. It functions to hold the

Therefore, the original IF is held in the document holder 5, and it is transferred to the fifth
As shown in the figure, if the image I of the document F is projected onto the surface of the designated layout paper B by setting it on the holding part 62 at the lower part of the lamp house as explained in FIG. can be rotated to any angle, and the angle at that time can be input to the internal arithmetic and control unit as an electrical signal.

FIG. 8 is a diagram showing an example of a signal processing system in an embodiment of the present invention, in which data given from the rotary encoder 52 is sent to the arithmetic control section 12 via the signal input section 11.
However, the acquisition of data and the start of arithmetic processing by the arithmetic control unit 12 are controlled by the numeric keys and pushbutton switches numbered on the operation control panel 7, and the X-Y plotter A drive signal is outputted to the angle indicator 9, a display signal is outputted to the angle indicator 10, etc.

Next, the operation of determining the angle according to this embodiment will be explained.

■ Place the designated layout paper B (or a copy thereof) on the workbench 2, and at the same time set the original F such as color film in the document holder 5, and place the original on the surface of the designated layout paper B. Project an image ■.

■ Operate the magnification adjustment switch installed on the operation control panel 7, and place the original 11g against the layout designation figure drawn on the layout designation sheet B! Try to match the 1st pattern. Incidentally, the matching of the positions at this time is performed by shifting the layout designation paper B on the workbench 2.

(2) After completing the operation (2), operate the magnification display switch on the operation control panel 7, and the magnification at that time will be displayed on the magnification display 8.

As already explained, the operations from ■ to ■ are almost the same as those for well-known magnification measuring machines, and therefore,
For documents that do not require angle adjustment, the following operations are not necessary.

■ Once the pattern matches and the magnification has been determined, next operate the knob 53 to rotate the image I. match, and in this state press the reference angle setting switch on the operation control panel 7,
At this time, the data given by the rotary encoder 52 is taken into the arithmetic control section 12 as reference angle data.

② Operate the knob 53 again to rotate the image ② so that the pattern of the image 1 matches the designated figure drawn on the layout designation paper B again. In this state, the operation control t[l board 7
Press the angle calculation switch, and use the data from the rotary encoder 52 at this time as the measured angle data in the calculation section 1.
Incorporate it into 2.

■ When the reference angle data and the measurement-8 constant angle data are input in this way, at this point the arithmetic control unit 1
2 starts processing these data, calculates rotation angle data representing the rotation angle of the document, displays it on the angle display 10, and stores it in the memory.

■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 X-Y plotter 9, and thereby the X-Y plotter 9 starts graphic output operation. , a hard copy on which a predetermined angle indicating gauge figure is drawn is completed.

FIGS. 9a) and 9b) show how to select the measuring 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 should be selected mainly depends on the workability. Then, numbers are assigned to each side for this side selection. In the illustrated example, the top side of the manuscript, that is, the top, is taken as 1, and the clockwise direction is 2.3 as shown in a).
．． Set it to 4. The reference lines for measuring the angles of these sides 1 to 4 are 101, 102, 103 and 104, and each of the sides 1 to 4 and each of the reference lines 101 to 104 has an angle of θ1. θ2. θ3. Let it be θ4. The reference lines 101 to 104 consist of a reference line 101 having a reference angle of O°, 103 parallel to this, and 102 and 104 perpendicular to these reference lines 101 and 103.

Therefore, the angle θ2. θ4 can be replaced by an angle with respect to the reference line 101, for example. This is an angle with respect to the reference line 100 set slightly above the reference line 101 in FIG.
) as shown in the pasting lines 201, 202, 203, 204
Determine.

Figure 1 is a flowchart showing the operation details of the device in Figure 8.
These are shown as 1 to 1 and will be explained below.

First, perform the key effort to select the format (S
In this example, five types of formats are prepared, ranging from N(11 to Nα5), and here, as shown in FIG. The one with 18 sides is 100.6
c#IX 6cm film with 6 sides is 101
．． 35m 6 sides and 6 cm x 6 cm film 4
One side is 102.4 in x 5 in. One with two sides of film is 103.300 n + in x 180 m1
The number with n1 side is 104. Here, 11
0 to 114 are reference lines on the gauge on which square marks are pasted, corresponding to the reference lines on the scanning drum, and 120 to 124 represent originals pasted along with the pasting lines. These formats are arbitrarily determined within the range of paper dimensions that can be drawn with the built-in plotter.

Therefore, if you press any key from 1 to 5 (S2),
Any one of steps S3 to S7 is selected.

Since no end operation is performed at this stage, step S8 is passed and steps S9 to s15 are performed. In other words, the No. 8 predetermined for each manuscript is
The user inputs the input from the operation control panel 7 shown in the figure (S9), and then similarly inputs the magnification value for the document (slo). Next, after inputting the angle bus from the document holder 5 in the apparatus shown in FIG. 1 (811), the measurement blade number is determined as explained with reference to FIG. 9, and this is controlled by the operation control a shown in FIG.
512), and similarly input the output card number being formatted (s13).

Based on these inputs, the arithmetic control unit 12 in FIG. 8 calculates the drawing line, that is, the line including the pasting line (814), and uses the X-Y plotter 9 to place the prescribed pasting line, etc. at a predetermined position on the format A. Draw <(s15).

The operations of steps S9 to s15 are repeated for each original document, and pasting lines, etc. are drawn in each part of the format, and the original pasting gauge is completed.

FIG. 2 shows the drawing line calculation step (s14) in FIG. 1 in more detail.

First, in step S21, angle calculation is performed based on the angle pulse input in step S11 of FIG. Then, in step s22, radian conversion is performed, and then a line perpendicular to the measurement blade is determined (s23>).

After that, using this orthogonal line, find a line segment RR that connects the coordinate center to the intersection of the measuring blade and orthogonal line 1 in the x-y coordinates shown in Figure 3 a), and find the anti-coordinate of this line segment RR. Find the coordinate point P (XO, YO) at the center end as the contact coordinate (
824). Here, the term "contact point" refers to a point of contact between a drawn line and a circle as shown in FIG. In other words, the contact point coordinates P (X

Calculate the length of the drawn line segment based on 525), and calculate the coordinates of both ends of the drawn line segment based on this line segment length (s26>. These coordinates are calculated along the measuring blade with the contact seat 111iP (XO, YO) as the center. (Fig. 3b)
PI (Xl, Yl), 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 it includes impositions of the same size or different sizes. If the size is the same, calculation formula 1 is used as the first group528), if the sizes are different, calculation formula 1 is used as the first group528), and if different sizes are included, calculation formula 2 is used as the second group. Adopt (s29)
. Then calculate the center coordinates of the drawing area (530),
Forms the output translated in parallel to the drawing area (s31
).

[Effects of the Invention] As described above, the present invention measures the document angle and pastes the original at a predetermined position on a predetermined format I based on the measured value and the measurement side command and output position command that are input separately. It is possible to provide a document angle pasting gauge with drawn lines.

Therefore, the work of pasting a document onto the scanning drum of the scanner can be greatly streamlined.
