Abstract

PURPOSE:To confirm previously that a setting miss is present or not with seeing a sham ruled line indication on a CRT in an earlier step before a typing by indicating a ruled line in a step of a letter plate being fixed as the sham ruled line on the CRT. CONSTITUTION:Various setting data are stored in a recording circuit through a control circuit. Here, a signal indicating a ruled line printing from a ruled line switch 41 gives an instruction to a CRT controller 32 through the controller circuit 26, so that a sham ruled line is indicated by the following fixing and printing signals, and stored in a storing circuit 27. The instruction is given to the CRT controller 32 through the control circuit 26 by a fixing signal from a fixing switching-over switch 42 under this conditions so as to write the ruled line sham indication in a video RAM33 using various setting data on the ruled line in the recording circuit 27. The data in the video RAM33 are indicated in a CRT30 being conpounded by a video RAM28 and a composition circuit 29.

Description

Detailed Description of the Invention A. Object of the Invention [Field of Industrial Application] The present invention provides a CRT-equipped phototypesetting machine that displays characters that have already been printed and characters that are to be printed on a CRT. The present invention relates to a display device, more specifically, to a display device which displays various information regarding the ruled line printing as a simulated ruled line on a CRT before the actual printing when the ruled line is printed in a phototypesetting machine.

[Conventional technology]

Conventionally, among the above-mentioned display devices, there is a known display device in which ruled lines and characters are displayed on a CRT.

This is because in the case of text, the image of the typed characters is displayed on the CRT when the dial is fixed, and disappears when it is released, so it is possible to check the typed characters before printing. be.

In addition, in the case of ruled lines, those with a constant thickness or those with a thickness close to the actual ruled line have a power of 1.

FIG. 6 shows an example of a display on a CRT in a conventional display device. ) is a state in which the dial is fixed, (c) is a state in which the dial is released, and (b) is a state in which printing is actually performed.

As is clear from the figure, in the case of ruled lines, in the conventional device, even though the ruled line pattern (dots) is displayed when the dial plate is fixed as shown in (b), it is not possible to print how the actual ruled lines are printed. Therefore, it is difficult for the operator to check on the CRT whether there is a mistake in the ruled line printing settings, such as not setting the head, before actually printing.

Therefore, when printing ruled items, considering that it is difficult to correct mistakes such as cutting and pasting, operators must always be extremely careful to prevent mistakes such as typographical errors. This poses problems, such as placing an excessive burden on workers and making it impossible to improve work efficiency.

[Problems to be Solved by the Invention] Therefore, as a result of studies in view of the above-mentioned conventional circumstances, the present invention is configured so that the ruled lines set at the stage when the dial plate is fixed are displayed as simulated ruled lines on the CRT. This allows the operator to check the simulated ruled line display on the CRT before actually printing to see if there are any setting errors, making it possible to print ruled lines efficiently and without mistakes. The purpose is to reduce the burden on the operator.

9. Structure of the Invention [Means for Solving Problems] That is, the present invention provides a display device for a phototypesetting machine that displays characters that have already been printed and characters that will be printed on a CRT. A ruled line switch that specifies printing of connected ruled lines, a fixed switch that fixes the dial plate, a printing switch that commands printing, a memory circuit that stores ruled line data according to commands from the ruled line switch, and controls related to ruled line display; The device is equipped with a CRT controller to perform the printing, an image memory to store the entire printed character, and a control circuit to control these.The position and length of the ruled line actually printed on the photosensitive material is determined by the dial fixing signal from the fixing switch. The above-mentioned problems were solved by arranging the display 1 to display various information related to ruled line printing, such as the following, as simulated ruled lines.

〔Example〕

Embodiments of the present invention will be described in detail below based on the drawings.

FIG. 1 is a block diagram of the configuration of the non-inventive display device. First, based on the diagram, the process by which a character image is displayed on a CRT will be explained. The image analog signal is digitized by an A/D circuit 21, and compressed by a compression circuit 22 so that the size of the character image displayed on the CRT 30 is the same as the size of the character image actually printed. Ru. The compressed digital signal is sent to the CRT controller 2.
・Always written to frame memory O by IK. Also, video r/Koma 128 data is always CRT: 30
It is output to .

At this point, the CRT controller 24 controls the exchange of data between the frame memory B, the image memory 5, and the video RAh 128 in response to fixed designations and print commands from the control circuit 26.

Further, signals from each switch of the input switch group 13 are sent to the main body control device 12, pass through the I and 10 circuits 31, and reach the control circuit 26. The control circuit 26 is configured, for example, to issue a print command upon receiving a print signal, and to issue various commands in response to each signal.

Therefore, when a signal from the fixed changeover switch 42 in the input switch group 13 reaches the control circuit 26 and a fixing command is issued, the fixed character data in the frame memory n is fixed by writing it into the video 28. The characters will be displayed on the CRT.

Further, when the signal from the fixing switch 12 is a fixing release command, the fixed character data in the video switch 128 is erased to change the display to "tj".

Further, when a signal from the print switch 7/chi 43 in the input switch group 13 reaches the control circuit 26 and a print command is issued, the fixed character data in the frame memory 23 is stored as the entire printed character. Write to image memory 23.

In this way, printed characters and fixed characters are displayed.

FIG. 3 is a block diagram showing the general configuration of a phototypesetting machine with a CRT. , sensitive material drums 8 are arranged one after another, the dial plate 3 is fixed by a dial plate fixing noid 5, the desired characters on the dial plate 3 are transmitted through, and the desired letters on the photosensitive material 9 in the sensitive material drum 8 are fixed. A desired character is imaged at a position, and the sensitive material 9 is moved in biaxial directions by a feeding means comprising both X and Y pulse motors 11 and 10. The main body control device is configured to carry out the operation based on commands from switches (not shown) included in the other switch group 14 shown in the figure, and is no different from a conventional phototypesetting machine.

Also, the optical axis l reaching the photosensitive material 9 by the above mirror 6 is
FT is branched, and the translucent characters on the dial plate 3 are imaged by the imaging device 14 on the branched optical axis, and the imaging signal is provided to the image display device 15, so that the character image is displayed on the CRT 30. This is also similar to the conventional display device, so a detailed explanation will be omitted.

Next, the simulated display of ruled lines by the apparatus of the present invention will be described.

The method of drawing ruled lines is no different from the conventional device, and the other switches 14 in the manual switch group 44 are used to set the length of the beginning and end, that is, to set the length of ruled lines, etc. It is assumed that each shank setting has been made.

In other words, the above various setting data are already stored in the control circuit 26.
and stored in the memory circuit 27.

At this point, the signal indicating ruled line printing from the ruled line switch 4 is sent to the control circuit 26 so that a simulated ruled line is displayed according to the subsequent fixing and printing signals.
The command is given to the memory circuit 27 and stored in the memory circuit 27.

In this state, the fixed signal from the fixed changeover switch 42 causes the control circuit 26 to instruct the CRT controller 32 to write a simulated display of ruled lines to the video FtAM 33 using the data of various settings related to ruled lines in the memory circuit 27. give.

Video RAS (data in 33 is the video RAM2 mentioned above)
8 and is synthesized by a synthesis circuit 29 and displayed on the CRT 30.

That is, a simulated ruled line a as shown in FIG. 5 is displayed.

Moreover, since the simulated ruled lines are written in the video RA+M 33 by exclusive OR (XOR), they are erased by the same writing.

That is, if the fixing release signal is subjected to the same processing as the fixing signal, it will be erased.

The print signal from the print switch 13 is sent to the control circuit 2.
G to give a print command to the CRT controller 32.

In response to this printing command, the CRT controller 32 writes the actually drawn ruled lines in the image memory using the data regarding ruled line printing stored in the storage circuit 27 in the same manner as the fixed command.

In this way, by fixing and releasing the dial plate 3, the displayed 0 and the simulated ruled line display of the ruled line printing are erased.

Furthermore, when actually printing, the entire character image is written into the image memory 5, so that the same state as on the photosensitive material 9 is stored.

In short, when the dial plate 3 is fixed, a simulated ruled line equivalent to the actually printed ruled line is displayed.

Therefore, for example, a signal specifying the thickness of the ruled line may be applied from the other switch group 1-1, and the simulated ruled line may be strained to have the same thickness as the actual ruled line.

FIG. 4 shows a flowchart 1 related to the above operation.

In addition, in Fig. 5, (a) is the head not set, :, jM'
i”=”! - Various settings for markings such as selecting ζ turn have been made, (b) is the dial is fixed, C is the dial is unlocked, and (b) is the dial is unlocked. It is in a state where it has been actually washed and printed, and a' indicates the actual ruled line.

FIG. 2 shows another embodiment in which the CRT controller 24 and video RAM 28 are each combined into one.

Next, to explain the display of simulated ruled lines in another embodiment, the CRT controller 24
Then, a display of simulated ruled lines is written into the video RAM 28.

Further, by writing the displayed portion of the image memory B to the video RAM 28 in response to the character fixing release command, the display of the simulated ruled lines is erased.

Further, by writing a ruled line display corresponding to an actual ruled line into the image memory section in response to a print command, a state similar to that on the photosensitive material 9 is stored.

Therefore, in this embodiment as well, the display of simulated ruled lines is realized.

The other configurations and operations are shown in FIG. 1 and are the same as those of the previously described embodiment, so the explanation thereof will be omitted.

〔Effect of the invention〕

As explained above, since the display device of the CRT-equipped phototypesetting machine according to the present invention is constructed, the ruled lines equivalent to the lines to be actually printed are displayed at the stage before actual printing, that is, at the stage when the dial plate 3 is fixed. Since the ruled lines are displayed as simulated ruled lines on the CRT 30, the operator can
You can check whether there are any setting mistakes by looking at the simulated ruled lines, and if there are any mistakes, you can easily correct them at that stage.
If there are no mistakes, it is enough to print the actual ruled lines immediately, and the operator does not need to pay special attention to the printing of ruled lines or perform operations carefully, so he or she does not have to be mentally conscious. The burden is reduced,
Not only can this work be made light work, but it also avoids errors in the actual printing of ruled lines, which eliminates the extremely difficult correction work such as cutting and pasting, making the printing work easier. , and can be carried out efficiently.
