2. Description of the Related Art The preparatory work, which is the first process in a plate making process (image inputting process), is a work for predetermining the magnification, angle, trimming data, etc. of a document. The preparatory device for performing this work is used in a form as shown in FIG. That is, the preparatory device 47 includes the document 45 and the copyboard 46.
The above various data are determined from the above, and the determined respective data (parameter data) are stored in the flexible disk 48. Here, the blockboard 46 indicates how the original 45 is output, and a trimming area is drawn in advance on the mountboard. After the above determination, the operator carries the flexible disk 48 together with the original document 45 to the scanner body 49, and carries them to the scanner body 4.
It is set to 9. After that, the scanner main body 49 adjusts the brightness, gradation, color, etc. of the document, scans the document based on each data determined in the preparatory work, and outputs the result to the output device or layout. Output to the device 50 such as a system.

The document projection box 51 includes a loading port 52 for loading the document 45, and a light source (not shown) for projecting the document 45 loaded through the loading port 52. An operation panel 55 is provided on the front side surface of the projection table 54, and by operating the operation panel 55, a drive command can be issued to the vertical drive device 53 and the above-mentioned light source. That is, in response to the drive command of the operation panel 55, the light source is turned on, and the vertical drive device 53 drives the document projection box 51 in the vertical direction to change the projection magnification (simply referred to as magnification). At that time, data regarding the vertical position of the document projection box 51 is transmitted to the CPU 60.

On the projection surface of the projection table 54, a blockboard 46 is placed. A plurality of trimming areas are drawn in advance on the blockboard 46. In FIG. 17, just three trimming areas 57 to 59 are drawn, and a state in which a part (a desired image) of the projection 56 of the document 45 input to the input port 52 overlaps the trimming area 58 is shown. There is. The angle of the blockboard 46 at this time (inclination angle θ in the X direction or the Y direction [see FIG. 18])
The data relating to the positions and the data relating to the positions of the trimming areas 57 to 59 are measured by the digitizer of the projection table 54 and transmitted to the CPU 60. In addition, the operation panel 55
Also has a function of being able to specify the thickness data and the like of the blockboard 46 to the CPU 60.

The CPU 60 is a part for performing data collection, angle calculation, plotter data output, operation, data output and the like. A keyboard 61 (may be a mouse or the like), a plotter 62 and a monitor 65 are connected to the CPU 60 as peripheral devices.

The preparatory work by this apparatus is performed as follows. First, the procedure for measuring trimming data and the like will be described.

First, the blockboard 46 is placed on the projection surface of the projection table 54. Then, the manuscript 45 is inserted into the input port 52 of the manuscript projection box 51, and the operation panel 55 is further operated to turn on the light source and project it on the projection base 54.

The thickness of the blockboard 46 is set on the operation panel 55.

(B) The horizontal line (longitudinal direction) of the underprinting board 46 is measured by the above-mentioned digitizer, and the measured data is C
It transmits to PU60. The CPU 60 calculates the angle θ from the data.

(C) The frame of the projection 56 of the original 45 is measured by the digitizer, and the measured data is transmitted to the CPU 60.

(D) The frame of the trimming area 58 on the blockboard 46 is measured by the digitizer, and the measured data is transmitted to the CPU 60 as trimming data.

The above procedure is performed for each original 45. When these steps are completed, the CPU 6
0 writes and saves the above-mentioned magnification, angle, trimming data, etc. in the flexible disk 66. Also, CPU6
0 also displays those data on the screen of the monitor 65.

After that, the CPU 60 calculates the data of the position of each original 45 and the original frame from the data of the projection 56 frame of each original 45 and the magnification data, and outputs those data to the plotter 62. As a result, the plotter 62
The original frame 64 of each original 45 is drawn on the (transparent) sheet 63.

Next, various data such as magnification, angle and trimming data and how to transfer the original 45 to the scanner will be described. FIG. 19 schematically shows such a delivery method.
Is. Among them, FIG. 11A shows how to pass the various data, and FIG. 8B shows how to pass the original 45. First, since the above various data are already written as files in the flexible disk 66, the operator can take the flexible disk 66 to the scanner and set the flexible disk 66 in the disk drive of the scanner. good.

On the other hand, regarding the way of delivering the original 45, a pasting work is required. That is, the operator first sticks the manuscript 45 to the corresponding manuscript frame 64 and sticks it on the sheet 63, and after the sticking work is completed, the sheet 63 is stuck.
Will be carried to the scanner. When the scanner is a drum type, the sheet 63 is wound around the drum 67 and then fixed (or attached) by vacuum suction. On the other hand, in the case where the scanner is a flat type, the sheet 63 is left as it is or attached on the glass flat surface. Through the above work, the delivery of the original 45 is completed.

[0020]

However, the conventional preparatory apparatus has the following problems.

It is necessary to project the document up to the maximum magnification, and in order to maintain the magnification accuracy, the live projection device (the document projection box 51 and the vertical drive device 53 in FIG. 17) becomes large and heavy. Will tend to change.
Moreover, since the motor drive system is provided in the state as shown in FIG. 17, the size and weight are further increased.

It is necessary to use it in a dark place as a matter of course because it handles a projected image. Therefore, the working environment is poor for the operator, resulting in a decrease in work efficiency.

As shown in FIG. 17, the document projection box 51 needs to be moved up and down to determine the magnification, and a large amount of time is spent in determining the final position, which is a short time. There is a demand for a method that can determine the magnification.

It is necessary to measure the document frame.

There is a problem that it takes a long time to output the plotter of the document frame, and further, a manual work of sticking a document sheet is required, and this work takes a considerably long time. Also, because it depends on such manual work,
An error may occur when pasting the original sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of a preparatory apparatus which is an embodiment of the present invention. The apparatus is roughly divided into a document image input section, a digitizer 4, a data processing section centering on a CPU 9 (personal computer), and a plotter 12. The detailed configuration of each part is as follows.

The original image input section comprises a CCD camera 1 and a light table 2. The side view is shown in FIG. Here, the light table 2 is a photographing table on which the original 3 is placed, and is provided with an illumination light source (fluorescent lamp or the like) for illuminating the original 3 from below (-z direction) (not shown).
An arm extends upward (+ z direction) from the original placement surface, and the CCD camera 1 is attached to the tip of the arm. The CCD camera 1 can be slid vertically, and its position is the light table 2
The height is adjusted in advance so as to have an angle of view enough to cover the document 3 placed on. For example, in the case of a 4 inch × 5 inch document, the CCD camera 1 is fixed at an angle of view of 140 mm square. The symbols 1a and 1b shown in FIG.
Represents a diaphragm and a focus adjustment unit, respectively. or,
The output of the CCD camera 1 is connected to the CPU 9.

On the other hand, the digitizer 4 has a copyboard 5 for originals.
(Hereinafter, abbreviated as mount 5) is placed, and the digitizer 4 measures mount information V ₂ from the mount 5 and transmits it to the CPU 9. The contents of this mount information V ₂ will be described later. Further, on the mount 5, a plurality of trimming areas and mount layout images (corresponding to the image of the original 3) are drawn in the respective areas in advance. In this figure, exactly 3
In this case, three trimming areas 6 to 8 are drawn, and each trimming area 6 to 8 is accompanied by position information P1 to P3 called pairing information. That is, the mount layout images and the images of the originals 3 are associated with each other by the pairing information P1 to P3.

The data processing unit has the CPU 9 as a core,
This is a part consisting of the monitor 10 and the keyboard 11, and CP
U9 has a drive device for the flexible disk 15 as a storage medium. The CPU 9 receives the document image data V ₁ (original image signal) output from the CCD camera 1, displays the image on the screen 16 of the monitor 10 (image signal V ₄ for display), and outputs it by the digitizer 4. The mount information V ₂ and the data extracted from the document image data V ₁ by the command signal V ₃ instructed by the operator via the keyboard 11 are compared to calculate parameter data such as magnification and angle data. Details of this calculation processing will be described later. Instead of the keyboard 11, other input means such as a mouse, a light pen or a touch keyboard can be used.

The plotter 12 is provided with a transparent sheet 13, and the plotter 12 uses the sheet 13 based on the command signal V ₅ relating to the document frame output from the CPU 9.
Plot the document frame 14 on top.

Although the preparatory apparatus is drawn in the form of a block diagram in FIG. 1 described above, an overall perspective view of the apparatus is shown in FIG. 3 because it makes it easier to imagine the specific configuration of the apparatus. As shown in the figure, all the components are placed on the table TA for OA. That is, this device is configured as a table-top device. Therefore, the operator can perform the preparatory work as if he / she is operating the OA equipment (OA feeling). I will return to this point later.

Next, a work procedure using this apparatus will be described. A diagram showing such a work procedure is the flowchart of FIG. 4, and in order to make it easier to visually recognize the work, FIG. 5 shows an image on the screen 16 of the monitor 10 (FIG. ) And the mount layout image on the mount 5 ((a) in the same figure). Further, FIG. 6 shows a calculation procedure of each data. Hereinafter, these FIG. 4 to FIG.
Based on the above, the above work procedure centering on the processing in the CPU 9 will be described.

[Step S1: Mount Setting] First, the mount 5 is set on the digitizer 4. Then, based on the register marks (not shown) on the mount 5, the position coordinate data of the reference points (origin, horizontal direction and vertical direction) is read by the digitizer 4, and one of the mount information V ₂ (first mount information) ) As C
Input to PU9. Specifically, it is as illustrated in FIGS. That is, the coordinate values of the three reference points A (origin), B, and C that form the coordinate system on the mount 5 are measured, and the measurement results are transmitted to the CPU 9. The operator determines whether or not the mount 5 is in the original size, and if not, inputs the magnification of the mount 5 to the CPU 9 using the keyboard 11. Through the above work, the origin, inclination, and size of the mount 5 are known, and the coordinate axes on the mount 5 are determined.

[Step S2: Job Name Input] The job name (mounting sheet name) corresponding to the set sheet 5 is input to the CPU 9 using the keyboard 11.

[Step S3: Original Setting] Next, the original 3 is set on the light table 2 and the angle of view (height) of the CCD camera 1 is set. After the setting, the image of the original 3 is taken by the CCD camera 1 and the original image data V ₁ is taken in. After capturing the image, the CPU 9 converts the document image data V ₁ into a display image signal V ₄ and displays the document monitor image 19 as shown in FIG. 5B, for example. In the same figure, the document monitor image 19 is displayed in a tilted manner to intentionally show a case in which the document 3 is tilted when the document 3 is placed on the light table 2.

After the display, the operator measures the document frame by designating the cursor using the keyboard 11 while looking at the screen 16. Specifically, the CPU 9 receives the cursor designation and receives the four points PA, PB, PC, PO shown in FIG. 5B.
Position coordinates (values with respect to the coordinate axes in the screen 16 of the monitor 10) are calculated, and the document frame is determined by this.

[Step S4: Input of Original Number] The operator inputs the number (predetermined) of the set original 3 into the CPU 9 using the keyboard 11.

[Step S5: Measurement of Magnification / Angle] A mount layout image on the mount 5 (four points F in FIG. 5A,
The position coordinates of the characteristic points of the image surrounded by G, H, and I) are measured and input. In this embodiment, two points D and E are feature points.
Has been adopted. Of course, depending on the image contents, it may be difficult to specify the feature point. In this case, a plurality of points are specified for determining one feature point, and the center point of the plurality of points is determined as the feature point. To do. Further, the position coordinates of each feature point of the document monitor image 19 corresponding to these feature points are calculated. In the example of FIG. 5, exactly 2 points PD, PE
Is designated by the cursor, and the CPU 9 calculates the position coordinate values of the characteristic points PD and PE according to the designation.

These characteristic points (D, PD), (E, P
When the position data of E) is obtained, the CPU 9 next receives a command from the keyboard 11 and outputs two points (D, PD),
The magnification (when the document is output) and the angle (corresponding to the angle θ in FIG. 18 described above) required to match (E, PE) are calculated. The magnification is the distance between points D and E, and points PD and P.
The ratio of the distances between E and the angle can be obtained by calculating the angle formed by the line segment connecting the points D and E and the line segment connecting the points PD and PE. This enables conversion between the coordinate axes of the mount 5 and the original 3.

[Step S6: Trimming Measurement] The position coordinates of the four outermost points (in the horizontal and vertical directions) of the frame (referred to as a trimming frame) of the trimming area (6 to 8 etc.) of the mount 5 are determined by the digitizer 4. Measure with and enter. Here, the outermost point means a point where the trimming frame contacts the scanner area frame which is a rectangular frame. According to the example of FIG. 5A, the four points at which the trimming frame 17 is considered to be in contact with the scan area frame 18 are the four corner points F, G, H, and I, so these four points F, G, The position coordinates of H and I will be measured.

From the above, the four points F, G, H, and
When I (trimming frame) is determined, these mount information V ₂
On the contrary, the scan area (area surrounded by the rectangular frame 18) can be obtained by using. After calculating the scan area, the CPU 9 converts it and displays it on the screen 16 of the monitor 10. In FIG. 5B, it becomes an area surrounded by a frame 21 just indicated by a broken line. Further CPU
Reference numeral 9 converts the calculated scan area into a document size. Here, the converted data will be referred to as trimming data. The trimming data is a concept including the above-mentioned pairing information.

[Step S7: Confirmation] Next, the monitor 10
The position, the magnification, the angle, etc. of the trimming frame 20 are confirmed on the screen 16 and the data is finely adjusted if there is a mismatch.
That is, the mount layout image composed of dots, lines, figures, etc. from the mount 5 (in the example of FIG. 5A, the mount layout image 1
7) is measured by the digitizer 4 and input to the CPU 9 again. CPU9 is (a part of the mount information V _2: second mount information) data on these mount layout image screen 1 of the monitor 10 on the basis of the already calculated magnification and angle data
Converted to the data on 6 and displayed. Therefore, by comparing the two images displayed on the screen 16, it is possible to confirm whether the two images are completely overlapped.

[Step S8: Output] After confirmation and fine adjustment, the CPU 9 receives the command signal V ₃ from the keyboard 11 and writes each parameter data such as magnification, angle and trimming data in the flexible disk 15 and stores it. Further, the CPU 9 outputs a signal V ₅ regarding the document frame to the plotter 12, whereby the plotter 12 draws the document frame 14 of the document 3 on the sheet 13.

The delivery method to the scanner body is no different from the delivery method described in the prior art. That is, as shown in FIG.
The operator sets the flexible disk 15 in the disk drive of the scanner, sticks the original 3 into the original frame 14 on the sheet 13, carries the stuck sheet 13 to the scanner, and winds the sheet 13 on a drum or lays it flat. I do.

The preparatory apparatus of this embodiment described above has the following advantages.

The CCD camera 1 can be set by sliding it up and down to determine the position so that the angle of view is sufficient to cover the document 3, and the work is much easier than in the prior art. is there. Further, it is not necessary to measure the vertical position as in the prior art. This improves workability.

Further, unlike the prior art, a drive unit is not required, and the original image input unit is composed of only the CCD camera 1 and the light table 2, so that the device can be downsized and the weight can be made relatively light. You can Due to this size reduction and weight reduction, it becomes possible to make the preparatory device into a desk-top type device like an OA device (see FIG. 3).

Further, since the table on which the document is placed is a light table, the preparation work can be performed without any problem even in a bright room. This completely bright room promotes environmental improvement (bright image) and further improves workability.

In addition, in the present device, it is not necessary to move the mount 5 at all during the measurement, and only the digitizer operation and the keyboard operation are required. Therefore, the work load is significantly reduced, and the workability is also improved.

Further, in this apparatus, the operator mounts the mount 5
And a feature point (at least 2) on the screen 16 of the monitor 10.
It is only necessary to sample each point) and the CPU9
Automatically calculates magnification and angle data, so you can instantly calculate and determine these data.

Further, in this apparatus, since the confirmation work of superimposing both images on the monitor 10 is performed, the calculation accuracy of the magnification / angle data can be improved, and the confirmation work is controlled by the CPU 9. It is possible to speed up the confirmation work.

In this embodiment, although the original image is captured by the transmissive method in which the original is illuminated from below (-z direction), a reflective original may be used instead. In this case, it is not necessary to use the light table 2 in particular, and a table having a space for simply placing a document can be used. In any case, there is no difference in being able to perform preparatory work in a bright room. This point also holds true for other embodiments described below.

FIG. 7 is a diagram showing the structure of a preparatory apparatus according to another embodiment of the present invention. This apparatus is characterized by using a document holder. Therefore, the present apparatus is effective for a scanner having a holder rotation function of a document holder exchange type. Each component of this device is as follows.

The original image input section is also composed of a CCD camera 1 and a light table 2, and is the same as that shown in FIG. However, in this apparatus, the original 3 is not directly placed on the light table 2, but is set by sandwiching it in the original holder 22 and then placing the original holder 22 itself on the light table 2. At that time, the document holder 22 is fixed at a predetermined position provided in advance on the mounting surface of the light table 2. Therefore, the document holder 22 can be attached and detached with one touch.

Here, the structure of the document holder 22 will be described in detail. Next, FIG. 9 (closed state) and FIG. 10 (opened state).
Becomes As shown in both figures, the document holder 22 is
It has transparent plates 24 and 25 made of glass or plastic, and the original 3 is sandwiched between these two transparent plates 24 and 25. Therefore, even if the document holder 22 is placed on the light table 2 and illuminated from below, there is no problem in photographing. The symbol 23 indicates a holder frame.

The other components, namely the digitizer 4 and C
The processing unit centering on PU9 is the same as that of the case of FIG. However, as a result of using the document holder 22 in this apparatus, the plotter required in the apparatus of FIG. 1 is not necessary.

The present apparatus having the above configuration has the following advantages as compared with that of FIG. First, since the CCD camera 1 takes an image together with the original document holder 22 used in the scanner body, the position of the original document 3 is determined by the imaging. This is because the placement position of the document holder 22 is a fixed position and does not change. In addition, in the scanner body, the original 3 is automatically angled together with the original holder 22 based on the received angular data in the flexible disk 15. Therefore, the manual attachment work of the original document becomes unnecessary, and as a result, the plotter itself becomes unnecessary. Since plotters are generally expensive, the advantage of not using a plotter is great. Moreover, by eliminating the need for the above-mentioned pasting work, it is possible to eliminate any angle error that may have occurred in the past.

Further, by using the document holder 22, the document holder 22 can be attached / detached with one touch and delivered to the scanner body side as it is, so that there is a great merit in improving workability and productivity. Furthermore, since the measurement of the document frame, which was necessary in the apparatus of FIG. 1, is not necessary (because the document position is fixed), this can also contribute to the improvement of workability.

The data and the original 3 in this apparatus described above
FIG. 8 shows how to hand over.

FIG. 11 shows a modification of the preparatory apparatus shown in FIG. In this embodiment, the method of delivering the original is improved so that the original holder 22 is provided.
The stocker 27 that stores the is used. Therefore, the present embodiment can be applied to the scanner with the document holder continuous automatic feeding / discharging device 28. An example of such a scanner is shown in FIG. In the figure, reference numeral 30 denotes a scanner main body, a stocker 27 is placed at a position indicated by the reference numeral 29, and the stocker 27 is automatically inserted into the scanner main body 30 side by a document holder continuous automatic feeding / discharging device 28. It is automatically ejected from the scanner body 30 side. Document holder 2
The concrete method of handing over 2 is as follows.

A bar code is attached to the document holder 22, and the holder number corresponding to the bar code is input in addition to the parameter data on the side of the preparation device (by the keyboard 11 in FIG. 7), and the bar is placed on the side of the scanner. By reading the bar code with a code reader (not shown), the parameter data relating to the document holder 22 is searched.

In this modification, since the stocker 27 is delivered to the scanner, a plurality of document holders 22 (a plurality of documents 3) can be collectively prepared in advance while the scanner is continuously scanning. It is possible to prevent the operator from frequently coming and going between the apparatus and the scanner. As a result, it is possible to increase the operating rates of both this apparatus and the scanner, and it is possible to greatly contribute to the improvement of productivity.

FIG. 13 shows a modification of the modification of FIG. 11 in that a communication function is further provided to improve the method of transferring various parameter data by using a flexible disk. That is, the CPU 9 of the preparation device and the control unit 34 (personal computer) of the scanner are connected by the line 33,
A so-called personal computer communication can be performed between the both 9 and 34. As a result, it is possible to automatically exchange various parameter data directly without requiring a flexible disk and without human intervention.
As a result, it is possible to prevent the occurrence of troubles such as confusion in data transfer due to the correspondence with the stocker 27 and loss of the flexible disk to be transferred.

Further, FIG. 14 shows a modification of FIGS. 11 to 13. This modified example is an example using an automatic conveying device for a document holder, and as shown in FIG. 14, a device 37 for stocking a plurality of stockers 38, 39, 41 itself is provided on the side of the preparatory device. This device 37 has a light table 3 at the entrance side via a belt conveyor 36.
At the outlet side thereof, an automatic document holder automatic continuous feeding / discharging device 28 is provided via a belt conveyor 40.
