Description

[Detailed explanation of the invention] This invention relates to a phototypesetting machine, and in detail, if there is an error in the settings of each part of the phototypesetting machine, typesetting commands, etc. that prevents correct printing, the content of the error will be displayed in a text containing kanji. It relates to a phototypesetting machine that can be displayed on a phototypesetting machine.

In recent years, phototypesetting machines have become capable of displaying various errors, as in Japanese Patent Application Laid-Open No. 53-118023. In this Japanese Patent Application Laid-Open No. 53-118023, the details of the error to be displayed are, for example, "Code 1" for an error in setting the lens information, "Code 2" for an error in setting the feed amount, and "Code 3" for an error in setting the feed direction. "...If there is no remaining amount of photosensitive material, "Code 10" is used. If the lens is set out of the optical axis, "Code N" is used.
The contents of the error are analyzed in advance, a code is attached to each error, and the code is displayed.

Therefore, the operator cannot grasp the details of the error unless he refers to the displayed code with the comparison table. Also, instead of displaying the code, it can also be displayed in alphanumeric characters or kana, such as "MAGAZINE,""FILM,""LENS," or "Injiriyouikiover."

However, it goes without saying that it is much easier to distinguish if the text is displayed in kanji, such as ``Printing area exceeded,'' rather than in alphanumeric characters or kana.

However, in order to be able to freely display thousands of kanji characters, it is necessary to store the display data for that many characters in memory, read it out and display it as necessary, and simply display the "error content". It is not economically advisable to retain a huge amount of data (memory) just for displaying it.

In other words, as is well known, it is difficult for Japanese texts, including kanji and hiragana, to be made available for general use unless thousands of character types are prepared, and even though the number of error messages is limited, the number of character types used is There is no denying that the number will be quite large. As the number of character types increases, the memory capacity increases and the cost inevitably increases. If you want to avoid this, you will have no choice but to display in alphabets or kana as mentioned above.

The present invention is based on the points mentioned above, and is a phototypesetting machine that can display error contents without special preparation of kanji data for display when displaying error contents in sentences containing kanji. Its features include a rotating dial, a light source configured to illuminate a predetermined character on the dial when the character is positioned at a predetermined printing position, and a A photographic device comprising a first optical system that selects only desired characters from among the selected characters and forms an image on a sensitive material housed in a dark box, and a unit such as a feeding device that moves the image forming position relative to the sensitive material. The typesetting machine includes a reflecting mirror, a lens, a photoelectric conversion element, etc., and is configured to move freely in and out of the optical axis of the first optical system, and when the character image on the dial is projected, the first a second optical system that forms a character image from the first optical system through a reflecting mirror and a lens onto a photoelectric conversion element and converts the character image into a digital signal;
It decodes information from keys, switches, tapes, etc. that command the information necessary for typesetting, and sends commands to each of the above units, and also detects the setting status of each of the units and the second optical system, and calculates the setting status. and a control unit that outputs an error code signal according to the cause when printing becomes impossible by determining the commanded content, and a control unit that outputs an error code signal according to the cause, and when an error code signal is output from the control unit, a control unit that outputs an error code signal corresponding to the error code signal. a code conversion circuit that converts the code into a series of character codes and outputs it as a character code signal; and when an error code signal is output from the control unit, a code conversion circuit that issues a print prohibition signal and switches the second optical system to the first optical system. It is inserted into the optical axis of the system so that it can receive character images from the dial, and the characters corresponding to the character code signals sent from the code conversion circuit are sequentially selected from the dial. a control device that instructs the second optical system to convert the character image into a digital signal; and a register that sequentially stores the digital signals output from the second optical system in response to a signal from the control device. , and a display section that displays the contents stored in the register as a character image.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is an example showing a schematic external view of a phototypesetting machine according to the present invention. The phototypesetting machine 1 is roughly divided into an upper part 2 and a lower part 3, with a phototypesetting unit housed in the upper part and its control unit housed in the lower part. 4 is a panel provided with keys and switches 5 for giving various commands, and a display section 6 such as a plasma display. Reference numeral 7 denotes a magazine that accommodates exposed photosensitive materials. In addition, although omitted in the figure, it is assumed that all the members included in a normal phototypesetting machine are installed, including a tape reader, a puncher, and the like.

FIG. 2 is a block diagram showing an embodiment of the phototypesetting machine according to the present invention. Light from a light source 10 such as a flash lamp passes through a lens 12 to the dial 1.
Irradiate 3. The dial 13 is rotated by a motor 15 about a shaft 14, and contains an arbitrary number of various character symbols and control codes as is generally known. 16 is a selector that selects any one character from the dial. A lens 17 converts the image from the dial to an arbitrary magnification and forms the image on a photosensitive material 18. In the phototypesetting machine of this embodiment, the lens 12 described above,
The selector 16 and the lens 17 form a first optical system. The sensitive materials are housed in a dark box 19, and are detachably attached as an unexposed magazine 20 and an exposed magazine 21 (7 in FIG. 1). The photosensitive material 18 can be moved in the X and Y directions by a feeding device 22, and the necessary character feeding and line feeding are performed. 23 is an optical axis.

A mirror or prism 24 typically has an optical axis 23
It is moved into the optical axis 23 when a print prohibition command is issued from a control device 25, which will be described later. And the selector 16 illuminated by the light source 10
The selected character image on the dial 13 is reflected by a mirror 24, passes through a lens 26, and is imaged on an image sensor 27 such as a photo diode array. Then, the character image is photoelectrically converted into a digital signal and sent to a register 28, which will be described later, to be stored. A second optical system consisting of a mirror 24, a lens 26, and an image sensor 27 is moved in the direction of the arrow by a mirror control section 29 that is integrally formed in this figure and operates according to a command from a control device 25, and is moved along the optical axis 23.
The mirror 24 is connected to the mirror 24.

Reference numeral 30 denotes a control unit which receives signals from the control device 25 and commands the selector 16 to operate, selects the magnification of the lens 17, operates the feeding device 22, lights up the light source 10, etc., and at the same time controls the dial. Detection of the control code in 13, Detection of whether the selector 16 operates as instructed, Detection of whether the mirror 24 is set completely off the optical axis 23, Lens 1
Detecting whether the magazine 7 is set in the optical system, detecting whether the magazine is set in a predetermined position, detecting the remaining amount of the photosensitive material 18, detecting the operating status of the feeding device 22, etc. , is provided so as to function as a department that detects the state and determines whether or not it is in a printable state. These are each component (unit) 16, 17, 18, 1
If you install a switch etc. at 9, 20, 21, etc. and feed back the signal, you can easily check the contents,
You can know the status. Further, checking the contents of the formatting command and the operating state of the feeding device 22 can be easily grasped by exchanging information with the control device 25 having various calculation functions.
If it is determined that printing is not possible, an error code signal is output depending on the cause.

31 is a code conversion circuit that converts the error code signal from the control unit 30 into a series of corresponding character codes and transmits the same to the control device 25 as a character code signal; 25 receives various signals from the outside and performs overall control and calculations; For example, when an error code signal is output from the control section 30, the control device performs operations such as issuing a print prohibition signal.

32 is an OR gate, and 33 is a display section shown as 6 in FIG. 1, which displays information from the register 28. Numeral 34 is a key or switch shown by 5 in FIG. 1, which gives commands to the control device 25. 35 is a command tape.

Next, the operation will be explained. First, turn on the power, drive the motor 15, and rotate the dial 13. Next, use the keys and switches 34 to issue various commands, such as lens magnification and composition direction (vertical or horizontal composition).
etc. Then, the signal is transmitted from the control device 25 to the control section 30, which operates the lens 17 and the feed device 22 as appropriate to set them in a predetermined state.

Next, the instruction tape 35 is read by the machine and its contents are transmitted to the control device 2. The command tape can be used instead of issuing commands using the keys or switch 34, but various formatting commands such as number of characters, line length, line pitch, and data of characters to be printed are recorded.

When the character data is transmitted to the control device 25, a signal for each character is sent to the control section 30. Since the control section is sent a signal for reading the control code stored in the dial 13, when the two match, the matching signal is sent to the light source control section 36 to operate the light source 10.

On the other hand, since the selector 16 operates to select only the required character luminous flux, the designated character luminous flux passes through the lens 17 and reaches the photosensitive material 18. When printing is completed in this manner, the feeding device 22 feeds the characters based on the formatting command, and thereafter processes are performed one after another to finish printing a predetermined number of characters.

Next, a line feed is performed by the feeding device 22, and printing is continued in the same manner to create a printed matter in the desired format.

If an unexpected accident occurs during printing or when starting printing, such as a magazine setting failure, a conflict in the formatting command, or the printing area of the photosensitive material exceeds, the control unit 30 determines that printing is impossible and generates an error. The code signal is transferred between the code conversion circuit 31 and the control device 25.
tell.

The control device 25 immediately issues a print prohibition signal to stop reading the command tape 35 and stop the operation of the feeding device 22 and the light source control section 26. Furthermore, the prohibition signal is also transmitted to the mirror control section 29, which operates to set the mirror 24 on the optical axis so that the image from the dial 13 can be taken into the second optical system.

On the other hand, the code conversion circuit 31 that receives the error code signal converts it into a series of character codes corresponding to the error code, outputs it as a character code signal, and transmits it to the control device 25. If the code conversion circuit 31 is configured, for example, as a circuit in which a matrix is assembled so that a character code signal corresponding to the error content can be obtained in advance, an output converted into a character code can be easily obtained.

When the control device 25 receives a character code signal, it transmits the signal to the control section 30, operates the selector 16 and the light source control circuit 36 in the same manner as described above, selects the corresponding character from the dial, and mirrors its image. 2
4. The image is formed through the lens 26 on the image sensor 27 installed on the imaging plane of the second optical system. The photoelectrically converted digital signal thus obtained as the output of the second optical system is directed to the register 28 and sent to the storage signal from the control device 25 and the OR gate 3.
2, and is stored therein in response to a shift signal transmitted via 2. Thereafter, character codes corresponding to error codes from the control unit 30 are selected one after another, exposed, and stored.

The character codes stored in the register 28 are sequentially displayed on the display section 33 while being synchronized with a shift signal from the control device 25. This display content is, for example, "print, character, area, area, over, bar".
It becomes a sentence mixed with kanji like .

It is expected that multiple error items may occur at the same time, so prioritizing them according to the error content and displaying the items with the highest priority will allow you to take focused action. It is also possible to determine whether the error is causing a problem with printing.

The number of characters to be displayed on the display unit 33 can be determined arbitrarily, but if only the error details are to be displayed, one character should be 32 x 32.
Approximately 32 characters would be sufficient for bits.

FIG. 3 is an explanatory diagram of the image sensor 27 installed on the imaging plane of the second optical system in FIG. 2. A is a character on the dial 13, and in this example it is ``photograph'' (actually negative type is common). B is an explanatory diagram of an image sensor, which in this example is a 24×24 bit one. When the letter A is projected onto this image sensor, it will look like C. By scanning this image vertically in synchronization with the writing in the register 28 and shifting it sequentially, a signal corresponding to the character shape shown in D is obtained. Therefore, an image sensor that can cover an area for one character is sufficient.

FIG. 4 shows the image sensor 27, register 28, and display section 3 in FIG. 2, which correspond to C to D in FIG. 3.
This shows a specific example of No. 3. The image sensor 27 is of 24×24 size as in FIG. 3, and the character "figure" is projected onto it. register 2
8 corresponds to each Y column of the image sensor, and 28
-1 to 28-24 are prepared, and the number of digits is n×24, the number of characters displayed on the display section 33.
Since the address of the image sensor on which the image portion of the "figure" is projected is not in the X1 column, nothing is stored in address 1 of the register 28.

Then, by the shift signal from the control device 25,
When the X2 column is reached, the contents written earlier in the register are also shifted to address 2, and the contents of the X2 column become 1.
written to the address. However, since no image is projected on the X2 column, nothing is written yet.
Next, when shifted to the X3 column, "1" signals appear in Y15 and Y16, so they are transferred to register 28-
Write on 15, 28-16. Thereafter, the entire area of the image sensor 27 is scanned in the same manner, and the results are written into the register 28. Next, when the ``force'' is projected, it is scanned in the same way and its data is written. In this way, data corresponding to the commanded error code is created and sequentially transmitted to the display section 33 and displayed.

Although the above description has been made based on the embodiment shown in FIG. 2, the present invention is not limited to this. For example, the dial 13 is not only disc-shaped, but also drum-shaped, belt-shaped, wheel-shaped, etc.
The same is true for plate-shaped objects that move in XY. The light source 10 may be not only a flash lamp but also a continuous lighting type or a type using a shutter. In this case, the light source control section 36 can be read as a shutter control section, and the shutter can be replaced with the mirror 24.
If you install it on the front side (dial side), it can be processed in the same way. Furthermore, the image sensor can be replaced by other similar photoelectric conversion means, for example a vidicon. Many optical systems can be used without being limited to those shown. Similarly, many examples can be given, such as the sending device 22, the register 28, the code conversion circuit 31, and the display section 33.

As explained in detail above, according to the present invention, if an error occurs due to various information set in the phototypesetting machine or during printing, it will be detected and a printing prohibition signal will be issued to stop the printing operation. , generates the detected error content as an "error code", converts this code into a "character code" signal, and selects the corresponding character from the "dial" for printing already built into the phototypesetting machine. It is possible to select and expose them one after another and send them to the photoelectric conversion unit, and send the obtained digital signal to the display unit to display the error details in a sentence containing Chinese characters. In particular, we have made it possible for the dial containing characters to be printed to also be used as memory for error messages, so there is no need to prepare a huge amount of kanji data specifically for error messages. All contained characters can be used for error indication. Furthermore, as mentioned above, since errors containing kanji can be displayed using all the characters on the dial, the operator can immediately understand the error content without referring to a comparison table, etc., and can take correct action through quick dialogue. I can give lectures.
