[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a scanner device for inputting image data of a document, and in particular, it is possible to significantly improve the work efficiency of document scanning and improve the operating rate of the device. This invention relates to a scanner device.

(Prior Art) Conventionally, in plate making factories, for example, input devices such as layout scanner systems that can efficiently output images by arranging multiple images on one sheet of film have been used, for example, in the form of a rotating drum. Scanner devices are often used.

On the other hand, recently, flatbed type scanner devices have been used instead of these because of their high quality and high definition. This flatbed type scanner device has a flat document table like a copying machine, and scans the image data of a color document set on the document table by scanning the reading head on a flat surface (flat scanning). This is what you input.

(Problem to be solved by the invention) By the way, in such a scanner device, as one way to improve the efficiency of scanning work, it is necessary to operate continuous scanning (scanning multiple documents in succession) and to improve its effectiveness. It's going up.

However, in a drum-type scanner device, the number of documents that can be continuously scanned at one time is limited to the number of documents that can be pasted on the drum. Further, even in a flatbed scanner device, the number of documents that can be continuously scanned is limited by the number of documents that can be placed on the document table.

As mentioned above, with conventional scanner devices, the number of documents that can be continuously scanned is limited, which not only reduces the scanner's actual operating time (main scan time) but also increases the operator's work time. There is a problem in that the burden becomes heavy, and as a result, the work efficiency of document scanning decreases.

The present invention was made to solve the above-mentioned problems, and it dramatically increases the number of documents that can be scanned continuously (automatically), increasing the actual operating time (main scanning time) of the scanner, and The purpose of the present invention is to provide an extremely reliable scanner device that can reduce the operator's work time and lighten the burden, thereby significantly increasing the work efficiency of document scanning and improving the operating rate of the device. shall be.

(Means for Solving the Problems) In order to achieve the above object, a scanner device according to the present invention has a magnification angle calculation function that calculates magnification angle data such as document pasting line data and trimming data, and a scanner device based on the trimming data. an image input data creation means having a scan area calculation function that calculates scan area data using the image input data, and a sheet data creation function that stores the magnification angle data and the scan area data in a storage means in association with the recognition data of a document pasting sheet; , a drawing means for drawing the original pasting line on the original pasting sheet together with recognition data of the original pasting sheet based on the original pasting line data, and a drawing means for drawing the original pasting line on the original pasting sheet based on the original pasting line data, An extraction means for reading recognition data and extracting magnification angle data and scan area data corresponding to the recognition data; The pasting sheet is scanned based on each extracted data extracted by the extracting means, and includes a scanner that outputs image data of the document.

(Function) Therefore, in the scanner device of the present invention, magnification angle data such as document pasting line data and trimming data are calculated by the image input data creation means, and scan area data is calculated based on this trimming data.
Furthermore, this magnification angle data and scan area data are stored in the storage means in association with the recognition data of the document pasting sheet. Then, based on the original pasting line data calculated by the image input data creation means, the drawing means draws the original pasting line on the original pasting sheet together with the recognition data of the original pasting sheet.

On the other hand, when the original pasting sheet is set on the scanner document table, the recognition data of the original pasting sheet is read out, and the extraction means extracts magnification angle data and scan area data corresponding to this recognition data. . and,
A plurality of original pasting sheets on which at least one original is pasted based on the original pasting line are scanned based on the respective extraction data extracted by the extraction means, and the image of the original is extracted. Data is output.

This allows a large number of documents to be scanned continuously (automatically), dramatically increasing the number of documents, increasing the scanner's actual operating time (main scan time), and reducing operator work time. This reduces the burden, and as a result, it becomes possible to improve the work efficiency of document scanning and improve the operating rate of the scanner device.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example when the present invention is applied to a flatbed type scanner device. As shown in FIG. 1, the flatbed type scanner device of this embodiment includes an image input data creation device 1, a floppy disk 2 as a storage means, a plotter (or cutter) 3 as a drawing means, and an extraction means. It consists of a computer 4, a flatbed scanner 5, and external storage devices such as a magnetic disk 6, an optical disk 7, an MT 8, and a floppy disk 9.

Here, the image input data creation device 1 has a magnification angle calculation function that calculates document pasting frame data as document pasting line data, magnification angle data such as trimming data, and calculates scan area data based on the trimming data. It has a scan area calculation function to calculate the scan area, and a sheet data creation function to store the magnification angle data and the scan area data in the floppy disk 2 in association with the recognition data of the document pasting sheet. Note that the document pasting line data is not limited to the document pasting frame data, and may be data of two intersecting straight lines.

Further, the plotter (or cutter) 3 draws a document pasting frame on the document pasting sheet based on the document pasting frame data together with the recognition data of this document pasting sheet.

On the other hand, the computer 4 uses the flatbed scanner 5
The recognition data of the original pasting sheet set on the original table is read out, and magnification angle data and scan area data corresponding to this recognition data are extracted.

Further, as shown in FIG. 2, the flatbed scanner 5 has a flat document table 10 and an auto-feed mechanism (not shown), and has a plurality of sheets with at least one document pasted in a document pasting frame. A document pasting sheet is set on the document table 10 using an autofeed mechanism, and a reading head (not shown) scans the document in a plane (flat scanning), thereby printing the document based on the respective extraction data extracted by the computer 4. Scan the pasting sheet,
It outputs the image data of the original.

Further, the magnetic disk 6, optical disk 7, MT8, and floppy disk 9 are used to appropriately store image data from the flatbed scanner 5 together with recognition information.

Next, how to use the flatbed scanner device configured as described above will be explained in detail.

When setting a document on a flatbed type scanner, first, the image input data creation device 1 shown in Fig. 1 uses its magnification angle function to create document pasting frame data and trimming based on the specified layout paper. Measure and calculate magnification angle data such as data.

Next, a plurality of sheets (three sheets in this example) of Mylar or the like for pasting the manuscript are prepared. Based on the document pasting frame data measured by the image input data creation device 1, a manuscript pasting frame corresponding to a plurality of originals is placed on the manuscript pasting sheet together with the recognition data of this manuscript pasting sheet. , and draw (or cut out) using a plotter (or cutter) 3.

Here, the job name (number) and sheet name (number) are respectively drawn as the recognition data for the original pasting sheet. As a result, the original pasting sheets 11A, IIB, 11 as shown in FIGS. 3(a), (b), and (C), for example.
Create C. In Fig. 3, 12A, 12B, 12C are drawn or cut out original pasting frames, 13A, 13B, 1
3C indicates the cutout job name (number), 14A,
14B.

14C indicates the name (number) of the cut out sheet.

Next, as described above, the original pasting frames 12A and 12B.

12C1 job names (numbers) 13A, 13B, 13C1 sheet names (numbers) 14A, 14B, 14C are drawn on original pasting sheets IIA, IIB.

11C, the scan area calculation function of the image input data creation device 1 calculates scan area data (points for determining the scan area of the original on the original pasting sheet) based on the trimming data. This scan area data is calculated as follows.

In other words, the trimming area and the scanning area are
The relationship is as shown in the figure, and if the four points in the trimming area are A, B, C, and D, the scan start point S and end point E are S-(minimum X coordinate, minimum y coordinate) E-(maximum (X coordinate, maximum y coordinate).

Specifically, as shown in FIG.
By aligning the upper left corners of IA, IIB, and IIC,
Calculate scan area data. (Incidentally, the scan area may be set with some allowance for these.) Next, the original pasting sheets IIA, IIB, 1
The scan area data calculated above is corrected based on the difference between the origin of 1C and the origin of flatbed scanner 5. This scan area data is modified as follows.

That is, as shown in FIG. 5(a), the document pasting sheet 11A is placed on the document table 10 of the flatbed scanner 5.
Align it with the top left corner of the page. In this case, the origin of the flatbed scanner 5 is usually not the upper left corner as shown in FIG. 5(b).

Since the scan area data is the absolute coordinates of the origin of the original pasting sheet 11A, the coordinates that take into account the difference between the origin of the original pasting sheet IIA and the origin of the flatbed scanner 5 are the actual scan area. It becomes data. Specifically, it is the value obtained by subtracting ΔX and Δy.

Next, using the sheet data creation function of the image input data creation device 1, the magnification angle data and scan area data calculated as described above are associated with the recognition data of the document pasting sheet and written to the floppy disk 2. Make me remember. Here, in addition to the job name (number) and sheet name (number) described above, the document name is stored as the recognition data for the document pasting sheet.

Next, the pasting sheet 11A drawn as described above,
Paste the original into the original pasting frames 12A, 12B, and 12C of IIB and IIC, and paste the multiple pasting sheets IIA and I.
The IB and IIC are attached to the feeder portion of the flatbed scanner 5, and the first pasting sheet 11A is set on the document table 10 by the autofeed mechanism.

Next, the computer 4 reads the recognition data of the document pasting sheet IIA set on the document table 10 of the flatbed scanner 5, and extracts magnification angle data and scan area data corresponding to this recognition data.

Next, in the flatbed scanner 5, the original pasting sheet IIA is scanned based on the extracted data extracted by the computer 4 by flat scanning with a reading head (not shown), and 12 sheets are scanned. The image data of the original document is stored on the magnetic disk 6 along with the recognition data.

Next, the pasting sheet 11B is pasted by the autofeed mechanism.
are set on the original platen 10 of the flatbed scanner 5, and scanned in the same manner as the pasting sheet 11A, and the image data of the ten originals are stored on the magnetic disk 6 together with the recognition data. Furthermore, the last pasting sheet 11C is set on the document table 10 of the flatbed scanner 5 using the autofeed mechanism, and scanning is performed in the same manner as pasting sheets IIA and IIB. The data is stored on the magnetic disk 6 along with the recognition data.

In this case, when the capacity of the magnetic disk 6 becomes full, scanning is stopped and image data is created and stored for each job name (number) on the optical disk 7, MT8, floppy disk 9, etc., and the magnetic Free up the storage area on disk 6 and continue scanning. Furthermore, the number of unmanned automatic scans can be dramatically increased by storing the captured image data classified by job name (number) or the like using an autochanger type magneto-optical disk or the like.

As described above, the flatbed type scanner device of this embodiment has a magnification angle calculation function that calculates magnification angle data such as document pasting frame data and trimming data, and a scan area function that calculates scan area data based on the trimming data.

It has a computer 4 that reads sheet recognition data and extracts magnification angle data and scan area data corresponding to the recognition data, a document table 10, and an autofeed mechanism, and has at least one document pasted in the document pasting frame. Included multiple original pasting sheets IIA, II
Regarding B and 11C, the flatbed scanner 5 scans the original pasting sheet based on the respective extraction data extracted by the computer 4 and outputs the image data of the original, and the image data from the flatbed scanner 5. It is composed of an external storage device such as a magnetic disk 6, an optical disk 7, an MT 8, and a floppy disk 9 for storing recognition information as appropriate.

Therefore, it is possible to dramatically increase the number of documents that can be continuously (automatically) scanned, thereby increasing the actual operating time (main scanning time) of the flatbed scanner 5 and reducing the operator's work time. The burden can be reduced accordingly, and as a result, the work efficiency of document scanning can be increased, and the operating rate of the flatbed scanner device can be greatly improved. In addition, since you can set any number of originals on the original pasting sheet with scan area data (position information) before setting the original on the original table 10 of the flatbed scanner 5, it saves time for the staff working on the original. It can be used extremely effectively. Furthermore, since images of a considerable number of documents can be captured unattended, the number of scanner operators can be reduced.
