Description

The present invention relates to a method for mounting an original image to be duplicated on an image duplicating apparatus such as a color scanner in a required position in an image duplicating operation such as photoengraving. Regarding

[Conventional technology]

For example, when performing color separation reproduction of a color original image using a drum scanning type color scanner, it is common practice to mount an original image of a plurality of points in parallel on an original image drum.

That is, the color original picture is, for example, 6 × 6 cm or 10 × 1
The size is 3 cm (4 × 5 ″). On the other hand, since the original image drum of the color scanner has an area where multiple original images can be installed in parallel, multiple original images are installed to improve work efficiency.

When mounting this original image, if you set the tilt angle of each original image so that the trimming frame line based on the required layout matches the direction of the scanning line for each original image,
You will not have to disassemble to an unnecessary extent. That is, since the shape of the trimming frame is generally rectangular,
Decide the tilt angle of the original image so that the set trimming frame line matches the main scanning direction and the sub-scanning direction, and mount it, and turn the signal ON-OFF at the position of the trimming frame line to obtain image data only in the desired area. And work efficiency is good. In particular, when applied to input for electronic plate making, it takes time to electronically rotate an image, so it is desirable to angle the original image in advance as described above before scanning.

As means for determining the position and angle of mounting the original image,
There has been proposed a method of collectively mounting original images of a plurality of points by using a sticking mount (1) as illustrated in the figure. This is an outer frame line (2) showing a mounting position for each original image (shown by a dotted line for convenience of understanding) on an appropriate sheet, and a trimming line (3) in the sub-scanning direction showing a trimming area of each original image. (4), trimming line in the main scanning direction (5)
(6) and a reference line (7) which is a reference when the mount (1) is attached to the original image drum of the color scanner. The reference line (7) is drawn parallel to the trimming lines (3) and (4) in the sub-scanning direction.

Such a sticker mount (1) can be prepared by manual drafting, but in recent years, it has been desired to use a drawing device combining a projection digitizer and an XY plotter as shown in FIG. The pattern is designed to be created with high precision and efficiency.

Such a drawing device is well known, for example, as described in JP-A-61-29578.

The projection type digitizer (10) has a structure similar to that of a photo enlarger, and the original image to be duplicated is mounted on the original stage (11) and illuminated by a light source incorporated in the upper lamp house (12), and the lens (13). A projection image is formed on the lower projection table (14) via the.
An XY digitizer (15) is installed on the upper surface of the projection table (14), and an image of the original image is projected on the surface, and the original image table (1
Adjust the height positions of 1) and the lens (13) to form an image with the dimensions specified in the duplicate layout. At this time, the magnification display section (16) displays the replication magnification obtained based on the distance between the original table (11), the lens (13) and the digitizer (15), and the focal length of the lens (13). To be done. Further, the original image is rotated in the horizontal plane so that the desired trimming frame line in the projected image coincides with the X-axis and Y-axis directions of the digitizer (15), and the inclination angle is set.

Therefore, the cursor (17) is sequentially installed at each corner of the projected image and the position of the trimming frame line, each position data is input by the XY coordinate value, and the desired position data in the original image is cursored. Input by (17).

Each input position data is calculated with the computer (18) attached together with the duplication magnification data to create the data of the outer frame line and trimming frame line of the original image corresponding to the size of the original image, and the data is displayed on the CRT display (19). Display the shape of the frame.

This operation is repeated for a required number of original images, and after the data of the original images to be pasted are gathered, the XY plotter (20) is operated according to the data, and the desired original image outer frame line (2) and trimming frame are obtained. The lines (3) (4) (5) (6) and the reference line (7) are drawn on the paper in a size corresponding to the size of each original image, and the paste mount (1) as shown in FIG. To create. The position data may be calculated after inputting the position data on the digitizer (15) for all required original images.

Further, these data are also used as control data of the color scanner in scanning reproduction of each original image. That is, for each original image, an area included between the trimming frame lines (3) and (4) in the main scanning direction and between the trimming frame lines (5) and (6) in the sub scanning direction, An image signal is output as a duplicated area for each original image, and a duplicated image with desired trimming is recorded.

The following is a method of sticking each original image to a designated position using this sticking board (1).

First, the first method is to cut out the pasteboard (1) along each drawn outer frame line (2) to form a window hole, align each original image with the corresponding window hole, and fix it with an adhesive tape. To do. As a result, a plurality of original images are mounted on the pasting board (1) with the trimming frame lines (3), (4), (5) and (6) aligned in a certain direction.

Therefore, the paste mount (1) is wound around and fixed to the original image drum of the color scanner. At that time, the reference line (7) drawn on the pasting mount (1) is attached to the original image drum in advance in the sub-scanning direction (axial direction of the drum).
By setting the position of the pasteboard (1) so as to match the marked line and wrapping it, each trimming frame line (3) to
(6) is a posture that is aligned with the main scanning direction and the sub scanning direction,
Each original picture can be mounted on the original picture drum.

The second method is to use each outer frame line (2) and trimming frame line (3).
~ (6), draw a reference line (7) on a transparent sheet, align the respective original images on the transparent sheet and fix them with adhesive tape, and wind and fix them on the original image drum in the same manner as above. .

[Problems to be Solved by the Invention]

 The above conventional method has the following problems.

The technique of cutting out the first window hole requires precise manual work by a skilled person to cut out the window hole of accurate size and inclination angle for each original image, and it requires a large amount of work. There is a problem that it takes time and labor costs increase.

In addition, due to the difference in the thickness of each original image, the attached paste may be distorted, and when it is wound around the original image drum, it may not be completely adhered to the drum surface and may be partially lifted. The original image drum of the color scanner is several hundred r.
Since it rotates at a high speed of pm, if there is distortion or floating on the wrapped backing paper, there is a risk of peeling off during work, and the position of the original screen will be misaligned even if it is not peeled off. There is an inconvenience that the quality deteriorates.

Also, if dust or the like exists between the original image drum surface and the original image, white spots or the like will be recorded in the duplicate image, and the quality will be significantly reduced.Therefore, it is necessary to remove the dust sufficiently when mounting. It takes a very long time to completely remove dust over the entire area of the pasteboard having a large area, and it may take time rather than mounting the original images on the original drum one by one.

Further, in order to ensure the accuracy of the mounting position and the inclination angle of each original image, a non-stretchable sheet material such as Mylar sheet is applied to the pasteboard, but such a good quality sheet material is expensive, Production costs increase. Especially when cutting window holes on the pasteboard, if the spacing between the window holes is too small, the strength of the sheet may decrease, causing large distortion and damage. That is, it is necessary to arrange the respective original images at appropriate intervals, and there is a problem that the use efficiency of the mount and the operating efficiency of the color scanner are reduced.

In the method using the second transparent sheet, there is no need to cut out the window hole, but the problem of dust removal between the transparent sheet and the original image drum surface is the same as in the first method. When the original images are mounted side by side, it is more difficult to remove dust due to the large size of the transparent sheet. Further, as in the first method, since the whole shape of the outer frame line (2) of each original image is arranged and drawn so as not to overlap each other on the pasteboard (1), a considerable area is still required. However, the material cost problem has not been improved so much.

[Means for Solving the Problems]

The present invention relates to a method for mounting an original image, which saves time and effort for making a paste mount and reduces material cost by using a flat display device.

Output with coordinate values.

These position data are processed by a computer (18) and sent to a flat panel display device (21) such as a liquid crystal panel or a plasma element, and a reference line (22) and an original frame line (23) are displayed on the display surface. ), The trimming frame lines (24) (25) in the sub-scanning direction and the trimming frame lines (26) (27) in the main scanning direction are displayed in actual size. In the illustrated embodiment, the reference line (22) is provided in the horizontal direction, but this may be matched with the direction of the reference line of the original image mounting section in the image duplication device, and the uppermost end of the original image area to be duplicated. It is preferable to display at the position of.

In this display, when setting the data by the projection digitizer (10), if you enter the original image number for specifying the original image and display the original image number together with the trimming frame line, etc., many original images will be displayed. In the case of sequential processing, individual original images can be easily confirmed.

In FIG. 1, the outer frame line (23) of the original image is shown by a chain line for convenience of understanding, but it may be a solid line, and the entire frame of the original image frame is not necessarily displayed, and the corners of each corner are not necessarily displayed. You may only show the position.

Next, the duplicated original picture (28) is projected onto the digitizer (10).
As shown in the second figure, the transparent base adhesive tape is taken out from the original image stand, placed on the display surface of the display device (21), aligned with the displayed original image outer frame line (23), and positioned. Fix with (29). At this time, the adhesive tape (29) is attached to a position which covers a part of one line (24) of the reference line (22) and two trimming frame lines in the sub-scanning direction.

In this state, the reference line (22) visible through the original image (28) and the adhesive tape (29), the trimming frame line (24), and the two trimming frame lines (in the main scanning direction) intersecting the reference line (22) ( 2
A part of each of 6) and (27) is transcribed and drawn on the surface of the adhesive tape (29) using an appropriate material such as oil-based ink. Hereinafter, the reference line and the trimming frame line drawn on the adhesive tape (29) will be described by adding (A) to each symbol,
A) (24A) (26A) (27A). By this transparent drawing, a reference line (22) indicating the desired trimming position and trimming frame lines (24) (26) (27) are additionally displayed on the original image (28) having an inclination angle based on the desired layout. You can

Therefore, the original image (28) and the adhesive tape (29) are integrally removed from the display device (21) and attached to the original image attaching portion of the image reproduction device.

FIG. 3 is a perspective view showing a state where the color scanner (color separation / scanning duplication device) is mounted on an original image drum as an example thereof.

On the surface of the original image drum (30), a reference line (31) as a reference line in the axial direction (sub-scanning direction) is displayed at an appropriate place on the surface, and the reference line (22A) displayed on the adhesive tape (29). Align with the marked line (31) and attach it to the drum surface. At this time, the reproduction area of the original image (28) is arranged on the downstream side in the main scanning direction with respect to the trimming frame line (24A) by the rotation direction (arrow R) of the original image drum (30) in the color separation scanning. Further, the rear end of the original image (28) wound around the original image drum (30) is fixed with an appropriate adhesive tape (32).

Although FIG. 3 shows a state in which only one original image is attached to the original image drum (30), a plurality of original images may be attached in parallel, and when the original images are placed side by side in the axial direction (sub-scanning direction). Are shared with each other, and when they are arranged side by side in the circumferential direction (main scanning direction), a plurality of marked lines (31) are displayed in parallel at appropriate angular intervals, and each marked line is marked. Each original image may be positioned with reference to (31).

This original image drum (30) is attached to the color scanner, and at the time of photoelectric scanning, the position is input to the color scanner based on the trimming frame lines (24A) (26A) (27A) displayed on the adhesive tape (29). Then, it is possible to scan and input the original image area trimmed as desired.

In this case, only one trimming frame line in the sub-scanning direction is displayed, and there is no line corresponding to the trimming frame line (4) in the conventional means shown in FIG. 5, but this is the original image as described above. By placing the duplicated area of (28) on the downstream side in the main scanning direction with respect to the trimming frame line (24A), there is no practical problem.

That is, when the position data is first input by the projection digitizer (10), the position data of the trimming frame line on the downstream side is input to the memory device as the control data of the color scanner. Then, during photoelectric scanning, the trimming length in the main scanning direction for each original image is set to the original drum (3

This rotation angle amount is obtained by, for example, counting the required number of clock pulses output by a rotary encoder that is driven in synchronization with the original image drum (30), or the time required after scanning the reference line (31) by an appropriate time delay means. Only the output should be made.

In the above description, the case where the original image is attached to the drum scanning type color scanner has been described, but the present invention is not limited to being applied to the drum type scanner, and an image copying apparatus of another type, for example, a plane. Even in devices such as scanning scanners and plate-making cameras that mount original images on a flat surface, trimming frame lines (24) drawn on the original images (28) or transparent adhesive tape (29) are attached to those original image attachment parts.
A) or the reference line (22A) for aligning the positioning reference line is displayed, so that the method can be applied according to the above method.
