Description

[Detailed description of the invention] The present invention relates to an automatic typesetting device for a phototypesetting machine.

A phototypesetting machine, or phototypesetting machine, is a machine that does not use type, but searches for each letter from a plate on which letters are lined up instead of a letter matrix type photographic plate, that is, Japanese type type, takes a photograph, and prints it onto photosensitive paper. be. Letterpress and off-cent printing plates were created and printed using this photosensitive paper as the original image.

As shown in Figure 1, the traditional typesetting process for a phototypesetter is to look at the first character of the manuscript, keep this in mind, then figure out where on the character plate that character will be located.
The user searches for the character in the character plate, moves the plate so that the character is directly under the lens, determines the position, and then looks at the selected character through the peephole.

After this, steps such as font size, decoration, typesetting, etc. are performed. Then, the task is to look at the next character in the manuscript and repeat the typesetting process.

Various innovations and improvements have been made to the current phototypesetting machines to improve their operability, and the techniques for enlarging and reducing characters and changing the typesetting associated with them have been perfected.

However, it occupies most of the phototypesetting operator's operating time, and
For the typesetting work that decisively affects the quality, the human eye searches for the relevant character from the character plate, which is a list of kanji and kana, and then manually positions the character so that it is directly below the lens. However, the ease of this typesetting work remains a major problem.

Another drawback of conventional phototypesetting machines is that although each typed character can be checked each time, since they are photographed, it is not possible to check the characters that have already been typed, as with Japanese type. It is not possible to clearly confirm how far the characters have been marked or where in the character string they are located, and characters are found to have been marked twice or missing characters after they have been completely burned onto the original photosensitive paper. becomes. Correction work in such cases requires a considerable amount of effort, and if even one letter is missing, the entire page must be cut and shifted.

The present invention eliminates the drawbacks of such conventional phototypesetting machines, ■ Aim to automate typesetting work.

, ■ Aim to speed up typesetting work.

■ By displaying the original on the display and telling the user which character of which character string is currently being photographed, double marking or missing characters can be prevented.

The purpose is to

The present invention will be described below based on an embodiment. The phototypesetting apparatus of the present invention is constructed as shown in FIG. 3, and the work is carried out in accordance with the procedure shown in FIG.

In other words, the phototypesetter first picks up all the necessary kanji and characters in order using a kanji tablet (1) according to the manuscript. The picked up characters are displayed on the character display (5) in the order they were picked up, and by comparing them with the original, it can be confirmed whether the characters are arranged exactly as in the original. If it is in good condition, it will be put on a phototypesetting machine.

This phototypesetting device is here character display (5)
At the same time as the first character of the original is flashed, the character plate is automatically moved to position the character directly under the lens. This completes the typing work. When the processing for that character is completed by performing other operations, the next character on the cathode ray tube flashes in response to a completion signal, and the plate (6) is automatically positioned at that character.

In this way, all the characters to be used are first picked up, and after comparing them with the original, the positioning of the plate (6) is performed automatically, so there are extremely few errors and the time required for typesetting is reduced. It will be possible to accomplish work several times faster than before, and without having to worry about positioning.

The operation of the electrotype typesetting apparatus of the present invention will be described below along with the work procedure shown in FIG.

If you press a character on the kanji tablet (IA) with the indicator pen (IB), a character code will be generated and the micro combiator (2
) is done manually. The micro combinator (2) displays characters on the character display (5) and simultaneously stores them in the memory circuit (2C). This is repeated until the characters to be input are displayed on the screen of the character display (5), and then compared with the original.

If there are wings between the manuscript and the screen, use the Kanji Tablet +11 to make corrections. Check on the Character Display (5) screen whether the corrections have been made correctly, then press the OK button on the Kanji Tablet (LA). Press with an indicator pen. This is the lettering work, and next is the letter plate (
Proceed to 6) automatic positioning.

The first character entered is the character display (5)
At the same time as the character plate (6) flashes on the screen, the character plate (6) automatically moves to position the character directly under the lens. Therefore, if you need to change the size or decoration of the character shape,
After doing this, press the shutter to take the photo. When the shutter is pressed, the blinking of the corresponding character stops, and at the same time as the second manually input character blinks, that character is automatically positioned.

In this way, not only the characters are automatically positioned one after another, but also the character currently being typed is flashed on the screen of the character display (5) to determine which character in the manuscript will be executed. I'm trying to find out if there are any.

More specifically, the device of the present invention is comprised of five elements. Namely, Kanji Tablet Part (1), Ma・i°
Black computer section (2), servo controller section (3)
), a plate positioning device section (4), and a character display (5).

The Kanji tablet unit +1) selects a necessary character from the tablet and brings the indicator pen into contact with the position of the character, thereby generating and outputting the character code of the character.

The micro combiator section (2) has a kanji tablet section (
1) Read the character code output from and display the character on the character display (5),
It is used for editing, deleting, and storing information. Further, the servo controller (3) converts the position of the character on the character plate into a character code and a position code, and outputs the result as a position code.

The servo controller unit (3) drives the plate positioning device (4) based on the device code configured by the microcomputer (2) to display the character plate,
This controls the character so that it is positioned directly below the lens of the camera.

The plate positioning device section (4) is a servo motor.

The character plate (6) is moved while being controlled by a tacho generator, a position sensor, and a rotation-linear motion conversion mechanism.

The operation of the phototypesetting apparatus of the present invention will be explained using the control block diagram shown in FIG.

The kanji tablet section (1) includes a tablet circuit (IA),
The tablet left circuit (IA) consists of an indicator pen (IB) and a character code generation circuit (IC). Piezoelectric switches are placed at the intersections of wires arranged in a grid pattern, corresponding to each character, and when pressed with the indicator bar. It detects which character is pressed depending on where in the grid matrix the piezoelectric switch operates. The detection output is from the character code generation circuit (1
c), the data is converted into a binary number (2-1) and output to the microcomputer section (2).

The micro combinator section (2) includes a character code input circuit (2A), a memory circuit (2G), and a control signal input circuit (2).
F), position code output circuit (2E).

and display output circuit (2D), each circuit is an arithmetic processing circuit (
2B) via a data bus.

When the character code input circuit (2A) receives a character code input from the kanji tablet unit (11) and sends it to the arithmetic processing circuit (2B), the arithmetic processing circuit (2B) performs the following four processes.

First, if the input character code is decoded and passed to the display output circuit (2D), the display output circuit generates a character pattern to represent the character with dots on the character display. and character display (
5) Output. As a result, the character display (
5) The characters of the input character code are displayed.

Second, the characters on the screen displayed on the character display (5) are directly input and stored in the memory circuit (2C). This is to help when modifying the screen, which will be described later.

Third, the character code is x, Y of the character plate.
This is converted into a position code expressed as an absolute position of coordinates and output to the servo controller section (3). That is, the target position for positioning the corresponding character on the character plate directly under the lens is given to the servo controller section (3) as a position code.

Then, ll84 is to determine whether to proceed to the next processing step based on the result of the control signal input circuit (2F) which receives and receives the control result from the servo controller section (3).

In this way, the character code is accepted and displayed on the character display (5), and at the same time the screen is memorized in the memory circuit (2C), and during control, the position code is sent to the servo control unit (3). The answer bank of the control signal is obtained by outputting the control signal.

The servo controller section (3) controls a servo motor that moves the character plate (6) of the plate positioning device section (4) and positions the corresponding character directly under the lens based on the position code from the microcomputer section (2). Do the following.

The position code indicates the position of the character on the character plate (6), but in reality, in order to position the character directly under the lens, the character plate is moved around the X-axis and by servo motors for the Y-axis. Therefore, the position code needs to be converted into the moving direction and moving distance of the character plate with the lens as the origin.

The position code input circuit (3A) receives the position code from the microcomputer section (2) and receives it from the arithmetic processing circuit (3B).
give to The arithmetic processing circuit (3B) converts this position code into the moving direction and moving distance of the character plate from the origin. On the other hand, the current position of the character plate (6) is obtained from a positron sensor input circuit (3D), which receives inputs from positron sensors (4C) and (4C'), such as a pulse encoder or a magnetic scale.

Therefore, the control direction and control distance of the character plate (6) are determined for the X-axis and each of the seven wheels from this current position and the movement direction and movement distance from the above-mentioned origin.

In other words, when the current position is (x@l)'o), the moving distance from the origin is (X+ +
)'+ ), then the control distance is lXo + l on the X axis, and Iyo + y11 on the Y axis.

As a result, if the rotation direction and speed are instructed to the servo motor control circuit (3C), the servo motor control circuit (3C)
) rotates servo motors (4A) and (4A'),
The rotation speed of each servo motor is controlled by detecting and feeding back speed generators (4B) and (4B').

The rotation of these servo motors (4A) and (4A') moves the position of the character plate, but the movement of these positions is as follows:
It is detected by the positron sensors (4C) and (4C'), is taken into the arithmetic processing circuit (3B) via the position sensor input circuit (3D), and the above-mentioned calculation is performed again.
Instructs the rotation direction and speed to the servo motor control circuit (3C).

By repeating this control, when the character given by the position code is positioned directly under the lens, the arithmetic processing circuit (
3B) outputs a positioning completion signal to the microcomputer section (2) via the control signal answerback circuit il&(3E).

Plate positioning device section (4+ is servo motor (4A)
), (4A'), speed generator (4B), (4B
'), Posisilon sensor (4C), (4G').

It consists of a mechanism that converts the rotational motion of a servo motor into linear motion and a plate stand (6), and is controlled by a servo motor controller (3).

As described above, the present invention provides a character selection device that outputs an input character such as a kana or kanji character selected by a necessary means as a predetermined character code, and a character selection device that outputs a character corresponding to the character code output from the character selection device. A processing unit that outputs a position code corresponding to the position of a character on a phototypesetting character plate while displaying it at a predetermined position on a CRT screen; This typesetting device for a phototypesetting machine is equipped with a servo device that controls the front, back, left, and right positions of a phototypesetting character plate so that the characters are placed under the photographing lens, and thus has the following effects.

■ Character selection devices such as desktop kanji tablets are faster at finding characters than character plates.

■ Machines are faster than moving plates by hand.

■ Character display is better for correction work than Kiribari
(CRT) is faster.

As a result of the above, the conventional typesetting work and correction work are extremely speeded up. Also, ■ It is easier to see characters on a character selection device such as a kanji tablet than straining your eyes at a character plate.

■ Do not move the plate by hand.

As a result of the above, the mental pain of phototypesetters is greatly alleviated.

Furthermore, (1) Since correction work can be performed on the character display, errors are almost eliminated and high quality can be obtained.
