Description

Description: TECHNICAL FIELD The present invention relates to a method of using an original sticking sheet for a scanner, which is used when capturing an image of an original from a scanner in printing plate making.

(Prior Art) In recent years, a layout apparatus in which a layout work required for printing plate making is performed using a computer has been widely used. In this apparatus, a manuscript is generally attached to a rotary drum type scanner, the image data scanned by scanning the manuscript surface is temporarily stored in a memory such as a magnetic disk, and the subsequent layout processing is performed using the stored contents. .

That is, first, the image data previously stored in the memory is taken out and displayed on the display screen, and the cursor image showing the trimming range and the image of the original are arbitrarily moved on this screen to the position designated by the layout mount. The pictures of the specified manuscript are inserted one after another. As a result, the required range of the original image is trimmed, and this is assigned to the designated position on the image surface of one page.

(Problems to be Solved by the Invention) However, with this method, it is difficult to specify the position in the display image, the skill and time are required for the work, and the position error is likely to occur. Therefore, accurate layout is difficult, and a display device having a special function for layout is required, which tends to be an expensive device.

In addition to the above method, when reading a scanner original image, a method of reading image data after previously specifying the dimension data of the portion of the original to be trimmed and the position to be trimmed on the scanner with a keyboard or the like Is also known.

However, this method also has a drawback that it requires a great deal of skill and time to measure dimensions and specify positions.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a method of using a document sticking sheet, which allows a trimming range of a document to be specified accurately and easily on a scanner.

(Means for Solving the Problem) In order to achieve this object, the present invention provides a scanner document sticking sheet in which a plurality of figures showing a trimming range of a document calculated based on the scaling factor of each document are formed on the sheet. Prepared, and after pasting the original corresponding to the figure portion on this sheet, then stuck the sheet on the scanning drum of the scanner,
Provided is a method of using an original sticking sheet for a scanner, which inputs an input start point of a scanner and takes in trimmed original image data.

(Operation) In the present invention, a plurality of figures showing the trimming range of the original document calculated based on the scaling factor of each original document are formed on the sheet, and the sheet on which the original document corresponding to this figure portion is pasted is a scanner. The original image data that has been trimmed can be captured by pasting it on the scanning drum of No. 1 and inputting the input start point of the scanner.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an apparatus for creating an original sticking sheet for a scanner of the present invention and performing an automatic trimming layout for a printing student, and FIG. 2 is a plan view showing an example of the original sticking sheet for a scanner of the present invention. is there.

In the figure, reference numeral 1 is a scanner, and a document 2 is placed on the scanning drum.
Set and capture the image data. A rotary encoder 3 is attached to the scanning drum. Linear encoder 4 for forming axial position data of the scanning drum
Is combined with the scanning head 13 of the scanner 1, and the rotary encoder 3 and the linear encoder 4 can extract the scanning head position data on the scanning drum. This position data is given to the control device 5 together with the image data from the document.

In addition to this scanner, a memory 6, a data tablet 7, and a mask cutter 11 are connected to the control device 5. The image data taken out by the scanner 1 is stored in the memory 6. Further, the layout mount 8 is set in the data doublet 7, position data on the layout mount is input by the cursor 9, and the scaling factor is input from the numerical data input element of the menu area 10 and given to the control device 5. In addition, the mask cutter 12 has a mask film 12
A is set, cutting is performed based on the data from the control device 5, a figure showing the trimming range of the original is formed, and the mask plate is used as the original sticking sheet for the scanner of the present invention.
12B is created.

At this time, the control device 5 performs a calculation based on the position data on the layout mount and the layout information containing the scaling factor input from the data tablet 7, and gives a cutout signal to the mask cutter 11.

Next, a method of making a document original sticking sheet for a scanner and a method of using the same will be described using the apparatus shown in FIG.

First, the layout mount 8 is set at a predetermined position on the data tablet 7 at a predetermined angle, and the position data of a predetermined point on the layout mount 8 is input to the control device 5 by the cursor 9. For example, in the case of trimming a document into a rectangle, position data is input to this rectangle at two points, the upper left corner and the lower right corner. After that, the scaling factor is input from the cursor 9 using the numerical data input element of the menu area 10.

The input position data and scaling data are stored in the internal memory of the control device 5 and subjected to arithmetic processing and then given to the mask cutter 11. In the mask cutter 11, the mask film 12A set based on the signal from the control device 5 is cut, and a mask plate 12B is created by cutting out a trimming range of the same size as the input range of the original.
At this time, a plurality of masks are cut on one mask film. Further, instead of the mask cutter 11, a plotter may be used to draw the trimming range of the original on the transparent film to create the mask plate 12B.

In this way, the mask original 12B as shown in FIG. 2, that is, the original sticking sheet for a scanner of the present invention in which a plurality of figures showing the trimming range of the original are formed on the mask film or the transparent film is prepared.

After this, on the mask or figure part on the mask plate 12B,
A document such as a photographic film is attached while referring to the layout mount 8.

Next, the mask plate 12B on which the original is stuck is stuck on the scanning drum of the scanner 1, and the scanner 1 captures the image data of the original. Needless to say, pay attention to the orientation of the mask plate 12B at this time.

When capturing image data from the scanner 1, the rotary encoder 3 and the linear encoder 4 input the input start point SP shown in FIG. In the illustrated case, the trimming range is a rectangle, so the input start point is the upper left corner point. The trimming range of the original is obtained from the position data of the input start point SP and the trimming range calculated by the control device 5 based on the allocation information from the data tablet 7. Multiple originals are pasted on the mask plate 12B, but if there is one input starting point SP for each mask plate, the input starting point SP will be for other originals on the mask plate 12B.
Since the relative position from can be calculated, the trimming ranges of other documents can also be obtained.

Then, the scanner 1 scans the original 2 pasted on the mask plate 12B, and the image data is taken in only while scanning the inside of the figure formed on the mask plate 12B, that is, within the trimming range. This makes it possible to take in the trimmed document image data.

The image data taken in this way is stored in the memory 6, and the layout processing is automatically performed in the control device 5 by this image data and the allocation designation information stored in advance in the memory 6 as well. Are again stored in the memory 6. The layout-processed data stored in the memory 6 is output to create a printing original plate.

In the above embodiment, the trimming range of the original stuck on the scanning drum of the scanner via the mask plate 12 is
Although it is determined by the calculation based on the position data of the input start point SP and the allocation information from the data tablet 7, the input end point is directly input from the rotary encoder 3 and the linear encoder 4 as in the input start point, and the document is trimmed. The range may be determined. In case of FIG. 2, this input end point is
It is a point on the diagonal line from the input start point SP, that is, the lower right point of the illustrated rectangle.

(Effect of the Invention) As described above, in the method of using the original sticking sheet for a scanner of the present invention, a plurality of figures indicating the trimming range of the original calculated on the basis of the scaling factor of each original are formed on the sheet. , The document corresponding to the graphic part on this sheet is pasted, the sheet on which the document is pasted is pasted on the scanning drum of the scanner, and the input start point of the scanner is input, thereby taking in the trimmed document image data. For,
Even if multiple originals with different scaling factors are used on the scanner without complicated position specification using an expensive display device as before, or complicated size measurement and position specification on the scanner The trimming range can be specified accurately and easily.
