Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an image pickup tube that images characters on a dial, a circuit that processes the imaged characters in various ways, and a photosensitive material that captures both character images from a CRT dial and character images from a CRT. The present invention relates to a phototypesetting machine that is equipped with an optical system configured to guide the image and can easily print a variety of characters.

Using a manual phototypesetting machine, from the letters on the dial as shown in Figure 1 (A), to the cover letter (B), the shaded cover letter (C), the shaded background pattern letter (D), and the overlap of two letters. Leave blank (
Creating various types of diversified characters such as overlapping characters (e) separated by spaces) is a very tedious task. In other words, the conventional method for creating diversified characters is to first print characters on a dial like (a) on sensitive material, and then move the sensitive material up, down, left and right to make the character (a) thicker and make it even more vivid. Create bold characters by burning into i. And the resulting thick letters and the original (i)
By photographically synthesizing the characters in Figure 1 (b)
, (Ha), and make a bag letter (Ha) with Akira.
By combining it with the background pattern or cutting out a part of it, you can create the shaded background pattern characters in (d) and the 2nd pattern in (e).
Overlapping characters were created by separating the overlapping parts of two characters with a space. Moreover, since these operations involve repeated exposure and development operations, they are extremely time consuming, and the intermediate photosensitive material is completely wasted. In addition, when obtaining a printed matter having both diversified characters and normal characters, each character must be created completely separately and then combined, which reduces work efficiency.

In view of these points, the present invention provides an image pickup tube that images characters on a dial, a circuit that digitally processes the imaged characters in various ways to create diversified characters, and a CRT that displays and confirms the results. , and a phototypesetting machine that consists of a CRT or other device that can project the thus created diversified characters onto a photosensitive material, and that can print by combining the digitally created diversified characters with regular characters. Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 2 schematically shows an example of a phototypesetting machine according to the present invention. In the figure, 1 is the light source of the phototypesetting machine, 2 is a condenser lens, 3 is a dial, 4 is the main lens that determines the size of the characters, 5.6 is a half mirror, and this is a prism or optical path as necessary. It can also be a mirror that goes in and out. 7 is a mirror,
8 is a photosensitive material, 9 is an image pickup tube, 10 is a CRT for printing, 11 is a CRT for display, 12 is a digitizer that decomposes the character signal sent from the image pickup tube 9 into digital signals, and 13 is from the digitizer 12. A first buffer memory that stores the sent signals; 14 a second buffer memory that temporarily stores the character signals stored in the first buffer memory 13 when performing diversification processing; 15 a diversification buffer memory; processing circuit, 16
1 is an output control circuit that selectively outputs video signals to the display CRT 10 and the printing CRT 11; 17 is a refresh memory with a capacity for one screen; and 18 is a third buffer that stores data that has undergone diversification processing. It's memory.

When performing normal printing in the phototypesetting machine configured as described above, the dial 3 is moved back and forth and left and right to position the desired character below the main lens 4.

When a shutter (not shown) is opened or closed, a character image is photographed on the photosensitive material 8 and printed.

3- Also, when displaying the image of the character to be printed on the display CRT 11 during printing, when the desired character on the dial 3 is positioned at a predetermined printing position, the image of the character is captured by the image pickup tube 9, and the image is captured by the digitizer. At step 12, the image is decomposed into black and white dots and stored in the first buffer memory 13. Then, the image is displayed at a predetermined position on the display CR 11 through the output control circuit 16, and the printing position,
If the size, shape, etc. of the printed characters are appropriate, the shutter is opened and closed to print on the photosensitive material 8. Then, a feeding control circuit (not shown) feeds the sensitive material, and at the same time, the contents of the first buffer memory 13 are stored in a position corresponding to the printing position of the sensitive material in the refresh memory 17. Then, when the next character is entered, the signal of the character digitized through the same process is stored in the first buffer memory 13, and is displayed on the display CRT 11 in the same manner as above, and the same operation is repeated.

When printing diversified characters, the digital data of the desired characters is stored in the first buffer memory 13 in exactly the same manner as described above, and then this data is sent to the second buffer memory 14. Then, the diversification processing circuit 15 performs various diversification processing, and when the processing is completed, the data is sent to the third buffer memory 18 and stored therein. Then, this diversified data is sent from the third buffer memory 18 to the output control circuit 16, and is sent to the display CR.
Display on T11.

After confirming that the displayed content has undergone the desired diversification processing, the information is sent to the printing CRT 10 for printing, and at the same time, the data is sent to the refresh memory 17 to match the printing position. write in the specified position. Also, if the diversification processing is not performed as desired, look at the display CRT and issue a command to the diversification processing circuit again to perform additional processing or write the contents to the refresh memory and then erase the contents. You can do something like this.

By configuring the phototypesetting machine as described above, even if a printed matter requires diversified characters, the diversified characters can be created on the spot, projected onto a printing CRT, and printed, making it very easy. Moreover, printed matter can be created in a short time.

The configuration is also very simple, since it is only necessary to add a diversification processing circuit and a CRT for printing.

In the above explanation, the case in Figure 1 was shown as an example of the diversification process, but the diversification process is as shown in Figure 1.
It is not limited to ``,'' but there are various types such as double border characters and combinations of double border characters and shadowed characters. Furthermore, although the explanation so far has taken the case of characters as an example, this is not limited to only characters, and the same processing can be applied to figures, pictures, and the like.

Furthermore, although the characters to be subjected to the diversification process have been described as being obtained from the dial, it goes without saying that they may also be obtained from a storage device that digitally stores character images. Further, although the above description has been made using a manual phototypesetting machine as an example, it is obvious that an automatic phototypesetting machine can be constructed in exactly the same manner.

An example of the diversification processing circuit is described in detail in Japanese Patent Application No. 57-2H213 filed by the applicant, but the principle of this circuit will be briefly explained with reference to Fig. 3. As an example, this explains how to thicken the original character image and take the difference between the result and the original character image to create a closed character as shown in Figure 1 (mouth), where the inside of the solid line is black. For convenience, only the outline is shown.

Now, if the image of FIG. 3(A) is taken by the image pickup tube and is a character stored in the first buffer memory 13, first, the character image of (A) is moved left and right by n and then stored. Then the third
Since a character image like the solid line part in figure (B) is obtained (the dotted line is the character image of (A)), next time shift this character image up and down by n and do it like (C) and (D). (The dotted lines in the figure indicate the shape of the data one step earlier, respectively). Then, as shown in (E), data of the character (A) that was imaged is made thicker by n in the vertical and horizontal directions, so this data (
If we remove the part corresponding to the imaged character (A>) from E), the first R-imaged character image (F) will be obtained.
Data (blanket character data) is obtained in which the part A) is blank and the outline (hatched part) is bordered. Note that the above explanation is about the case where the imaged characters are made thicker on the outside to create a cover letter.
The logical product of the character data stored in the first buffer memory and the character data stored in the first buffer memory is calculated. Then, compared to the image of the character 149, data is obtained that is narrower in the vertical and horizontal directions, so by removing the part corresponding to this data from the character data in the first buffer memory,
Data of a boxed character bordered inward by n is obtained.

By repeating exactly the same process, it is possible to create characters with shading, shading envelope characters, shading characters with a background pattern, and other diversified characters.

As described above, the phototypesetting machine according to the present invention has a simple configuration, and
The present invention enables the creation of diversified characters, which conventionally required much time and effort, to be performed at the same time as printing, resulting in a very large effect.
