Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a typesetting system, and is particularly suitable for use in a typesetting system in which a manual phototypesetting machine is used to create a block for printing. be.

[Summary of the invention]

The typesetting system of the present invention displays the draft manuscript supplied from the computer-aided design device on the display screen of the display, generates letter pattern information and feed information corresponding to the display content on the display screen, and By making it possible to print originals created with the device on photosensitive material, it is possible to easily and highly print originals with complex figures, symbols, or characters in a typesetting system using a manual phototypesetting machine. This allows for accurate creation.

[Prior art f4'i] A typesetting system using a manual phototypesetting machine is known as a device for creating a block for printing. The phototypesetting machine has a glass dial on which negative letters, symbols, etc. (hereinafter referred to as letters/1. patterns) are arranged. This dial is supported so as to be movable along the X-axis direction and the Y-axis direction, so that a desired letter pattern can be provided on the optical axis of the optical system. Then, the letter pattern placed on the optical axis is enlarged or reduced by a lens and photographed letter by letter on a photosensitive material such as film or photographic paper to create a block copy.

Manual phototypesetting machine combines blank printing function and main printing function,
When operating with the blank printing function, a mechanical shutter provided in the optical system is closed. Therefore, at this time, the character 1'&pattern selected by the operator is not imaged on the sensitive material, but is displayed on the display surface of the display device. In addition, character pattern information and feed information corresponding to the display content on the display surface are created during blank printing.

When performing actual printing, that is, when exposing the photosensitive material, the preset pattern is selected based on the preset pattern information and feed information created during blank printing, and the drive of the photographic optical system such as the feed mechanism for the photosensitive material is controlled. Then, the block created on the display surface of the display is exposed to light-sensitive material. In this way, by formatting on the display screen and then exposing the photosensitive material, it is possible to freely change, insert, and delete characters, and by changing the content, expensive This prevents the sensitive material from being wasted.

(Problem to be solved by the invention) In order to be able to display figures on printed matter, typesetting Soste J, which uses a manual phototypesetting machine, is also equipped with a drawing function. For example, during blank printing, a letter pattern for drawing line segments such as nine dots or corner dots is brought onto the optical axis and a bright spot is displayed on the display surface.Then, the input device is operated. This is done by moving the bright spot and drawing a line on the display surface.

Even with manual phototypesetting machines, line segments such as straight lines and arcs can be drawn by manually inputting the addresses of the start and end points and the connection information between these two points, automatically moving the bright points. It is now possible to do so. However, drawing with a manual phototypesetting machine is time-consuming because it involves moving the bright spots in this way. In addition, there is a limit to improving the finish quality such as the consistency of intersections, and it has been difficult to create a block plate that can be used for high-grade printing.

By the way, if a computer-aided design device such as CAD is used, complex figures, symbols, etc. can be created easily and accurately. However, the plotter used as a printing device for such design equipment has poor printing accuracy compared to phototypesetting machines, so even if a draft manuscript is created using this type of equipment, it will not work as a draft. No usable prints could be obtained.

In view of the above-mentioned problems, the present invention proposes a typesetting nostem that can easily and accurately create a block copy of a printed matter on which multiple Pffi figures, symbols, characters, etc. are drawn. shall be.

[Means for Solving the Problems] In order to solve the above problems, the typesetting system of the present invention includes a memory 3 that stores drawing data S1 of a draft manuscript 31 created by a computer-aided design device (CΔD30).

〔Example〕

FIG. 1 is a block diagram of a typesetting system showing an embodiment of the present invention.

In the figure, a photographic optical system 1 includes a light source 2, a reflection SA 3, a condenser lens 4, and a mirror 5, similar to a conventional phototypesetting machine.
, dial 6, main lens group 7, deformable lens group 8, image rotary prism 9, beam splitter prism 10
, a right-angle prism 11, a shutter 12, a travel lens group 13, a magazine drum 14, etc., and a photosensitive material 15 is wound on the magazine drum 14.

The dial 6 is supported movably in the X-axis direction and the Y-axis direction in a horizontal plane by a dial frame. Then, the dial frame driving section 18 moves the dial 6 to bring a desired letter pattern onto the optical axis, and the dial frame fixing section 19 fixes the letter pattern on the optical axis.

The travel lens group 13 is provided on a slide mechanism 20 and is moved along the X-axis direction indicated by an arrow 22 by a pulse motor 21. Further, the magazine torrent 14 is rotated as shown by an arrow 24 by a pulse motor 23. As a result, the photosensitive material 15 wound on the magazine drum 14 is moved along the Y-axis direction with respect to the optical axis 25. Therefore, the photosensitive material 15 and the optical axis 25 are mutually movable in both the X-axis and Y-axis directions. The driving of these dial frame drive unit 18, dial frame fixing unit 19, pulse motors 21, 23, etc. is controlled by a driving CPU 26, and the content formatted on the CRT display device 38 is printed on the photosensitive material 15. Ru.

Next, the operation of creating a block copy using the typesetting system of the embodiment will be explained. First, an operator operates the CAD 30 and creates a draft manuscript 31 on its display surface. By creating the draft manuscript 31 with the CAD 30 in this way, it is possible to create a complicated draft manuscript 3 as shown in the front view of the building in FIG. 2, for example.
1 can be made accurately and easily. CAD30
The drawing data S of the draft original 31 created on the display screen of is applied to the input terminal 32 of the typesetting system as draft creation information.

On the other hand, the input device 33 of the typesetting system is operated to input a write command and a display command for the drawing data S given to the input terminal 32. As a result, the drawing data S is written into the memory 35 provided in the control circuit 34, and this drawing data S1 is provided to the display CPU 37 via the control CPU 36.

The drawing data S1 given to the display CPLJ 37 is written into the buffer memory and converted into a displayable format. That is, for example, if the given drawing data S1 is three-dimensional data, it is converted into two-dimensional display data S2 by a conversion matrix and written into the frame memory. By supplying this display data S2 to the CRT display 38, the draft manuscript 31 of FIG. 2 created with the CAD 30 is displayed on the display 3 of the typesetting system.
8 can be displayed.

When the externally created draft manuscript 31 is displayed in this manner, the letter pattern information and feed information corresponding to the display contents are not generated. Therefore, unless these pieces of information are generated, the original image 31 displayed on the display f38 cannot be printed.

Therefore, using the displayed block manuscript 31, character pattern information S4 corresponding to the content displayed on the display 38 is generated.
and the sending information 11 SS is generated. That is, for example, by operating the keyboard of the human-powered device 33, a letter pattern for forming a desired line is brought onto the optical axis 25. This letter pattern is imaged by an image pickup device such as a CCD equipped with an 1ui & element, and is displayed on the display surface of the display device by the function of the display CPU 37.

The operator operates the input device 33 to designate a line segment on the draft manuscript 31 using the displayed character pattern, and inputs a command to draw the designated line segment using the character pattern. As a result, data regarding the designated line segment, that is, data representing the start and end points of the line segment and the connection manner between these start and end ends is read out from the memory 35 of the control circuit 34. Based on the read data, lines are automatically drawn on the display surface using the letter pattern placed on the optical axis. At the same time (or when all blank printing is completed), the printing information calculation means provided in the control circuit 34 generates feed information and character pattern information and writes them into the memory 35.

Such a blank printing operation will be explained with respect to the block original 31 shown in FIG. 2. This document is drawn with lines of three different thicknesses, such as a thin line 41a, a medium line 41b, and a thick line 41C. Therefore, the operator sequentially places letter patterns for thin lines, medium lines, and thick lines on the optical axis, and instructs line segments to be ruled using the letter patterns. By performing these instructions for all line segments, the draft manuscript can be placed on the photosensitive material 15 during actual printing.
All the feed information and character pattern information necessary for printing can be obtained. In addition, when performing cotton drawing, the consistency of the intersections of each line, etc. should be taken into account and corrections should be made as necessary. Also, at this time, you can freely change the thickness of the line segments, change the design, etc. It should be noted that if the color and brightness of line segments that have been ruled by the letter pattern are changed, the actual print information generation work will be facilitated.

The typesetting system of the embodiment can automatically generate main print information +U only by keypole operation, without having to hold the letter pattern on the optical axis and draw lines. In this case, a character selection menu is displayed on the display surface of the display device 38 by pressing the key 1 of the input device 33, and a desired character button is selected from the menu. Then, a line segment using the selected character pattern is designated on the display screen.

When such an operation is performed, the control C
The PU 36 automatically generates the character pattern information and the sending information. Therefore, the work of generating the actual printed information becomes easier.

The character pattern information YaS4 and the feed information S obtained in this way are transferred from the control circuit 3.1 to the driving CI) by operating the main print key of the input device 33.
26. Then, as in the conventional case, it is led out from the drive CPU 2G to the pulse motors 21, 23, dial frame drive unit 18, dial frame drive unit 19, etc. As a result, the character patterns necessary for main printing are sequentially placed on the optical axis, and the sensitive material 15 is moved in the X-axis direction and the Y-axis direction relative to the optical axis 25, so that the character patterns necessary for main printing are placed on the display surface. The prepared draft manuscript is automatically printed on the photosensitive material 15. Therefore, by developing the photosensitive material 15, it is possible to easily create a block diagram with a complicated drawing as shown in FIG. The block obtained in this way is a CAD3
Since the draft manuscript was created with 0, the finish, such as the consistency of intersections, is good. In addition, since the printing is done optically, similar to conventional typesetting systems, the printing quality is good. Therefore, the block created by the typesetting system of the embodiment can be fully used as a block for high-quality printed matter.

Another example of a block copy that can be created using the typesetting system of the embodiment is shown in FIG. The block diagram of FIG. 3 shows an example of a floor plan of a house, and is used as a block copy of printed materials such as advertising flyers and housing information magazines.

In this case, unlike the above-mentioned block copy, line drawings and characters are drawn. Therefore, as shown in the draft manuscript diagram of FIG. 4, a line drawing portion 46 is created using the CAD 30 to form a draft manuscript 43. Then, as described above, the drawing data S1 of this draft manuscript 43 is used as draft creation information at the input terminal 32 of the typesetting system.
and display it on the display 38. While looking at the displayed line drawing, the operator operates the input device 33 to draw the lined letter pattern on the optical axis, and also operates the image rotary prism 8 to move the line drawing along the optical axis,
By synchronizing the axes and the Y-axis, an arc representing the opening and closing of the door is drawn. In addition, the character part 44 is drawn with the character pattern on the optical axis, and the display 38
Create a draft manuscript on the display screen. In the process of creating the draft manuscript in this manner, the character capital pattern information S4 and feed information S necessary for actual printing are generated, and these information 11s4, s are stored in the memory 35. . Then, by reading out these information S4S5 and controlling the photographic optical system 1 during actual printing, the photosensitive material 1
5 to be printed.

FIG. 5 is a diagram showing an example of a musical score created. in this case,
A line drawing portion 46 is created using the CAD 30.

That is, first determine the pinch between the staves and draw the first row of staves. Next, do the overall layout and draw the staves in the second and subsequent rows one by one. Then, the line drawing portion 46 is completed by sequentially drawing vertical line portions, that is, starting lines, measures, etc. The drawing data S1 of this line drawing portion 46 is given to the typesetting system as block preparation information. In the typesetting system, a musical symbol part 47 such as a treble clef, a music score, or a pound sign, a character part 44, etc. are written from the dial 6 during blank printing.

Then, by appropriately rotating each character pattern, adjusting the spacing between patterns, or drawing diagonal lines, a desired layerer 1 is performed and blank printing is completed. below,
In the same manner as described above, the main printing key is activated to perform main printing on the photosensitive material 15.

In this way, the typesetting system of the embodiment uses a draft manuscript created by the CAD 30 when creating the draft manuscript on the display screen of the manual phototypesetting machine.

Therefore, it is possible to create printed materials that require complicated work, which could not be achieved using only a manual phototypesetting machine. Further, the finish such as the consistency of intersections can be improved, and a printing plate that can be used sufficiently as a high-grade printing printing plate can be easily obtained.

In the above embodiment, the graphic information 98,
In other words, an example is shown in which a line drawing section is created and the drawing section is provided to the typesetting system as block creation information. However, the typesetting process 1 of the embodiment. All the information that can be created with CAD 30 can be used as draft creation information. Therefore, not only figures and characters, but also various functional curves such as SIN curves and chemical formulas such as benzene rings can be easily created.

Alternatively, the character typesetting work may be performed on the CAD 30 side, and the typesetting system side may perform only the work of generating the capital pattern information S4 and the sending information IISS necessary for actual printing.

Note that the CAD 30 and the typesetting system do not necessarily need to be connected online. For example, the draft creation information created with the CAD 30 may be stored in a storage medium such as a floppy disk, and this may be reproduced and imported into the typesetting system as needed.

〔Effect of the invention〕

As described above, the present invention makes it possible to use a draft manuscript created with a computer-aided design device when typesetting on the display of a manual phototypesetting machine, so that complex figures etc. are not drawn. It is possible to easily and accurately create a draft of a printed matter, and the workability and accuracy of typesetting can be greatly improved.

In addition, since the draft manuscript created in this way can be printed with a printing means of a photographic optical system, it is possible to perform highly accurate printing, and to create a draft that can be used for high-grade printed matter. I can do it.
