Abstract

PURPOSE:To prolong the editing finish time of newspaper in order to add the latest information, by providing an input means to supply a recording data containing a specification data that sets the recording conditions of the picture information at the front part of a picture data. CONSTITUTION:When a subscan mobile stage 12 reaches the recording start position, a data transfer instruction is delivered to apply a data equivalent to a primary scan line to a recording part 13 having a picture signal modulating circuit. Then an instruction is delivered to drive a pulse motor 10 by one step. Thus a scan is set in. Then it is decided whether the picture data are all delivered or not, and an instruction is delivered to transfer the data equivalent to a primary scan line if the picture data are not all delivered. When it is decided that the picture data are all delivered, whether or not the stage 12 is at the return position of the specification data is decided. If the stage 12 is not at the desired position, an instruction is delivered to shift the motor 10 to the return position by one step to give the same inspection again.

Description

[Detailed description of the invention] The present invention relates to a newspaper recording device using a phototypesetting machine.

In recent years, the new production technology is HTS (letterpress method using lead type)
From then on to CTS (a typesetting method that combines computers and phototypesetting machines).

2. Newspaper editorial work is always done on a minute-by-minute basis in order to deliver the latest data to readers. CTS significantly shortens the editing time for newspapers compared to conventional HTS. Figure 1 is a large block diagram showing the flow of CTS newspaper production. 1 stores photos and text data from newspapers,
A large-capacity storage device 2 consisting of a magnetic disk or the like includes a large-capacity storage device 1, a newspaper editing command device 3 having an input section for photographic and character data, and a device 4 for recording one newspaper page on film. This is an electronic computer that controls the flow of data and the arrangement of data.

In the conventional CTS, a completed newspaper page is edited in the large-capacity storage device 1, and then film recording is performed in the recording device 4 all at once. Figure 2 shows the flow of newspaper production using this method on a time axis.

Newspaper production naturally has time constraints. Time t2 in FIG. 2 is a time limit at which film recording must be completed. The time t12 is the time required to record the entire paper surface on the film, and is a specific time depending on the capability of the recording device. Therefore, time t1 is the time limit for completing paper editing, and time t01 is the paper editing time.
Time t0 indicates the time at which page editing is started.

It can be said that breaking news is one of the important missions in newspaper production. Newspaper companies continue to strive to incorporate even a few minutes of new information into articles such as incident articles, sports articles, election news, and other articles. In FIG. 2, time t1 is the time limit for page editing, so if time t1 can be moved to a later time, more recent information can be edited.

By the way, looking at the contents of newspapers, in most cases only a small portion of the articles are close to the paper's editing time limit, and most of the other articles are likely to be edited within sufficient time. For example, in the example of the structure of the newspaper page shown in Figure 3, C
The advertising articles, A's editorials, explanatory articles, etc. have already been edited, and now we are waiting for B's articles to complete the editing of the entire paper.

At this time, if it is possible to record parts A and C on film first, and later record part B on the film when article B is created, then the page editing shown in Figure 2 can be done. This means that the time limit t1 can be extended to a later period.

FIG. 4 shows changes over time in the example of the editorial record of the newspaper page in FIG. 3. Time, t2 is the film recording completion time limit, time t1 is the editing limit time for article B, time t6 is article A, H
Time t is the end time of film recording, time t is the time when editing of articles A and B ends, and to is the time when paper editing starts. Therefore, toll is the editing time of article A and C part, t1/2/
is the film recording time of article A and C portions, t2/1 is the editing completion waiting time of article B, and t12- is the film recording time of article B portion. The time t12 in FIG. 4 is shorter than the time '12 in FIG. 2 by the fact that the film recording portion is smaller, and as a result, the article editing limit time t1 is extended.

The present invention has been made in consideration of the above points, and it is possible to limit paper editing by adding ingenuity to the data transfer format between the CTS equipped computer and the recording device and the scanning recording function of the recording device. It is an object of the present invention to provide a recording device capable of extending time further in advance and recording newer information.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 6 is a diagram showing the structure of data to be recorded. The data in parts A and C have already been edited, and the data in parts A and C have already been edited.
Consider the case where part B is recorded on film, and part B, which is edited later, is recorded on film later. The data is assumed to be main-scanned from left to right in the diagram and sub-scanned from top to bottom. The entire paper is 1ooo from the 0th line in the sub-scanning direction.
Up to the o-th line, the main scanning direction is from 0 pixel to 7000 pixels. Image data corresponds to 1 pixel and 1 bit, and 1
The processing unit of the computer is 1 word with 6 bits.

The square numbers in each line in FIG. 6 indicate word numbers. In this embodiment, the final word number of one line is the 437th word, and the pixel data is up to half of the 437th word. Taking the 3000th line as an example, this line includes a data area A to be recorded first and a data area B to be recorded later. The boundary between each data is the middle of the 187th word at the beginning, and the boundary between the 374th word and the 376th word at the end.

FIG. 6 shows the structure of recording data initially recorded on the film. The recording data includes specification data and image data, and in the specification data, the number of lines in the sub-scanning direction at the recording start position, recording end position, and return position after recording is expressed in hexadecimal numbers. , In addition, regarding the presence or absence of continuous data, 1' indicates presence, and 0'' indicates absent, and regarding the designation of positive/negative recording, 1' indicates positive, and o1 indicates negative. Note that the recording start position is shown in the Y0 line, the recording end position is in the Y4 line, and the return position is shown in the Y1 line in the configuration shown in FIG.

The image data shows the 3000th line. The shaded area is part B in Figure 5, which will be recorded later.
This is a portion that should not be recorded in the initial data, and since positive recording is performed in this embodiment, the data is 10#.

FIG. 7 shows the structure of recording data in data area B to be recorded later. The first recorded data shown in Figure 6 records areas A and C in Figure 6, and the later recorded data shown in Figure 7 records the remaining area B, so the continuation data of the specification data is 0. # indicates none. The recording start position is the same as the return position of the first recording data shown in FIG. 6, and indicates the Y1 line in FIG. Furthermore, the recording end position is shown in hexadecimal notation on the Y3 line in FIG.

The image data shows the 3000th line, which is the same as the first recorded data, and similarly, the shaded area is "O" data so as not to be recorded.

FIG. 8 is a block diagram of a rotary drum type recording apparatus which is an embodiment of the present invention. A film is wound around the surface of a rotating drum, and a small electronic computer 7 controls the operation of an image signal modulation circuit 8 and a pulse motor drive circuit 9 based on recorded data input from an input terminal 6, and drives the pulse motor. The pulse motor 10 is rotated by the drive signal from the circuit 9, and the pulse motor 10 rotates the feed screw 11 and moves the sub-scanning moving table 12 with this rotation. A recording section 13 having a light modulation recording element is placed on the sub-scanning movable table 12, and as the sub-scanning movable table 12 moves, light spots of light and dark are formed in accordance with the image signal modulation signal from the small computer 7. is applied to the film on the rotating drum 5.

FIG. 9 is a flowchart showing the control of the above recording apparatus, and the flow will be explained using FIG. 8.

First, it is determined whether the current position of the sub-scanning movable table 12 and the recording start position of the specification data in the recording data input to the input terminal 6 are the same. If they are different, a command is given to move the pulse motor 1o by one step in the direction of the start position, and the recording start position is determined again. When the sub-scanning movable stage 12 reaches the recording start position, it issues a data transfer command to give data for one main-scanning line to the recording section 13 having an image signal modulation circuit, and then) the pulse motor 1
Issue a command to drive o by one step and start the next scan.

Next, it is determined on page 9 whether or not all the image data has been output, and if the output has not been completed, a data transfer command for one main scanning line is issued. When it is determined that the scanning has ended, it is then determined whether the sub-scanning movable table 12 is at the return position of the specification data.

If they are different, a command is given to move the motor 10 one step in the direction of the return position, and it is determined again whether or not the return position is reached. When the sub-scanning movable table 12 reaches the return position, the series of operations ends. After the series of operations is completed, if the information in the specification data indicates that there is continuous data, the fill wrapped around the drum 6,
The printer waits for the next data to be sent without ejecting the paper or photographic paper.

FIG. 10 is a block diagram in which part of the control operation of the sub-scanning movable table is implemented in software.

21 is a rotating drum, 22 is a sub-scanning moving table, 23 is a feed screw for the sub-scanning moving table 22, and 24 is a position detector that detects that the sub-scanning moving table 22 is at the left end of the figure, such as a micro switch or the like. It's like a magnetic sensor. The output signal of the position detector 24 is 1' when detected, otherwise "
It is assumed that o' is also o z. 26 is a drive circuit for the pulse motor 26 directly connected to the feed screw 23, and when a pulse signal is input to the R terminal, the pulse motor 2 is driven in the direction to send the sub-scanning moving table 22 to the right side in the figure.
6 is rotated, and in the same way, when a Norse signal is input to the L terminal, it operates to send it to the left side.

27.2B, 29.30 are AND gates, 31° and 32 are OR gates, 33.34 are flip-flops for specifying the moving direction and moving speed of the sub-scanning moving table 22, respectively, and 36 is a (Russ oscillator with an N terminal). The F terminal outputs a pulse signal that matches the sub-scanning speed during recording, and the F terminal outputs a pulse signal that performs sub-scanning faster than during recording. 36 and 37 are latch circuits, 38 and 39 are matching circuits, and 4o is an up/down counter that counts up in response to a pulse input to the U terminal and counts down in response to a pulse input to the D terminal. The C terminal is an input terminal for clearing the contents of the counter to 01'. 41 is a computer interface, and 42 is a computer.

Assuming that the movable table 22 is stopped at an intermediate position as an initial state, the computer 42 can determine through the computer interface 41 that the signal from the position detector 24 is 602. (Since all information exchange between the computer 42 and the sub-scanning control system is performed through the computer interface 41, the explanation of this part will be omitted in the following explanation.) The computer 42 performs the following steps to initialize the sub-scanning control system. Perform the action. By driving the reset terminal R of the flip-flop 33 and setting Q=O and Q=1, the output signal can pass through the output signal source AND gate 28 of the OR gate 31. Next, the computer 42 drives the reset terminal R of the flip-flop 34 through the OR gate 32 to
=o, Q-1, and then set the signal line 43 to '''11, the signal at the F terminal of the pulse generator 36 becomes the AND gate 30,
ANDGATE 2 that allows you to pass through ORGATE 31 first
8 and enters the L terminal of the pulse motor drive circuit 26.

Therefore, the sub-scanning moving table 22 starts moving to the left in the figure.

The computer 42 monitors the state of the position detector 24 while
Wait until it reaches 1. At the same time, the Q signal of the flip-flop 34 is monitored to see if it becomes 1'' (because the content of the latch 36 and counter 40 in the initial state causes the coincidence circuit 3
It is possible that a match signal is output from 8 and drives the set terminal S of the flip-flop 34, making Q=1 and Q=0. This is because in this case, the N signal from the pulse generator drives the pulse motor, which slows down the moving speed of the moving table 22. ) When the Q signal of the 7 flip-flop 34 becomes 11'' while the signal of the position detector 24 is 01, the Q signal of the flip-flop 34 is passed through the OR gate 32 again as described above.
Drive the reset terminal R of No. 4 and set Q=o and Q=1.

When the position detector 24 reaches 11'', the computer 42 outputs the signal line 4.
3 to o1, the pulse signal going to the pulse motor drive circuit 26 is stopped, and the moving table 22 is stopped. Next, the computer 42 drives the terminal C to clear the contents of the counter 4o to 0. This completes the initial settings. The main states of the sub-scanning control system at this time are as follows.

5) The sub-scanning moving table 22 is located at the left end of the figure, and the position inspection - The signal of the black instrument 24 is "state 11.

■ Flip 70 that determines the moving direction of the sub-scanning moving table 22
The output of the knob 33 is Q=O, Q=1, and the moving direction is specified to the left side of the figure.

(2) The output of the flip-flop 34, which specifies the moving speed of the sub-scanning moving table 22, is in a state where Q=O and O=1, which specifies the fast forward speed.

■ Signal line 4 that instructs the movement and stop of the sub-scanning moving table 22
3 is "0", indicating a stop instruction.

■ The contents of the up/down counter are cleared to 0.

■ The contents of latch circuits 36 and 37 are undefined.

Next, the computer 42 first receives the recorded data shown in FIG. 6 and sets each parameter according to the contents of the specification data.

The contents of the recording start position are set in the latch circuit 36,
The contents of the recording end position are set in the latch circuit 37.

Next, drive the set terminal S of the 7-lip flop 33 and Q=
1. The moving direction of the sub-scanning moving table 22 is designated as Qo to the right side of the figure. Now, since the contents of the latch circuit 36 and the counter 40 are both 0, a match signal of the output of the minus number circuit 38 is output, and the flip-flop 34 is set, so that Q=1. Q=
It is in the O state. That is, the speed of the sub-scanning movable stage 22 during recording is specified.

Next, the computer 42 sets the signal line 43 to 61'', and the sub-scanning moving table 22 moves to the right side of the figure.
It enters the U terminal of 0, and the contents of the counter 40 are counted up. Although not shown, it goes without saying that the rotational speed of the drum 21 and the N terminal signal of the pulse generator 36 are synchronized. Also, in synchronization with this, each line signal of the image data is sequentially applied to the recording section (13 in FIG. 8).

When the contents of the counter 4o become the same as the contents of the latch circuit 3, a match signal from the minus number circuit 39 is outputted, passes through the OR gate 32, enters the R terminal of the flip-flop 34, and sets the output of the flip-flop 34 to 0=0.

Set Q=1. The computer 42 constantly monitors the Q terminal of the flip 70 knob 34 during recording, and when Ω = 0, the signal line 43 is set to ``01'', making it impossible to pass through the OR 16 page gate 30 and causing the sub-scanning movable stage 22 Next, the computer 42 sets the contents of the return position of the specification data in the latch circuit 36.Furthermore, the reset terminal R of the flip 70 knob 33 is driven to set the moving direction of the sub-scanning carriage to the left side in the figure. The computer 42 accurately determines the magnitude relationship between the recording end position and the return position of the specification data and determines the moving direction.) The output of the flip-flop 34 is always Q=
O.

Q=1, and fast forwarding of the sub-scanning movable table 22 is designated. Therefore, the computer 42 sets the signal line 43 to @1'', and the sub-scanning moving table 22 starts moving to the left side in the figure.The pulse signal that enters the pulse motor drive circuit 26 at this time simultaneously enters the D terminal of the counter 4o, The contents of the counter 4o are counted down. When the contents of the counter 40 become the same as the contents of the latch circuit 36, a match signal of the match circuit 38 is outputted and inputted to the set terminal S of the flip-flop 34, and the output of the flip-flop 34 is = 1. Set Q = o. During this time, the computer 42 constantly monitors the Q terminal of the 7th lip-flop, and when Q = 1, the signal line 43 is set to "0" to stop the sub-scanning movable table 22. In the record data shown in the figure, the contents of the continuation data in the specification data are present, so the computer 42 waits in this state until the next data is prepared.The main status of the sub-scanning system at this time is It will look like this:

(2) The sub-scanning movable table 22 is at the return position (09C4) 16 of the specification data in FIG. 6, and the signal of the position detector 24 is in the state of 1o''.

■ The output of the flip-flop 33 that determines the moving direction of the sub-scanning moving table 22 is Q=0. When Q=1, the direction of movement is specified to the left side of the diagram.

(2) The output of the flip-flop 34 which specifies the moving speed of the sub-scanning movable stage 22 is Q-1 and Q-0, which specifies the speed at the time of recording.

■ Signal line 4 that instructs the movement and stop of the sub-scanning moving table 22
3 is 0'' and is instructing to stop.

(2) The contents of the up/down counter 4o and the latch circuit 36 are both (09C4)16. The contents of the latch circuit 37 are in the state (271'O)16.

17. When the recording data to be recorded next as shown in FIG. . Note that if the contents of the sub-scanning system do not match the contents that are about to be set, a program is required to compare the contents of the two and move the sub-scanning system. According to
The program can be shortened by the amount compared above. Next, the set terminal S of the flip-flop 33 is driven so that Q=1. Q
=o to designate the moving direction of the sub-scanning movable table 22 to the right side of the figure. Now, the contents of the latch circuit 36 and the counter 40 are both (09C4)1. Therefore, the coincidence signal of the output of the minus number circuit 38 is output and the flip-flop 34 is set, so that Q=1.
．． The state is Q=o. That is, the speed of the sub-scanning movable table 22 during recording is specified. Next, the calculator 42
When the signal line 43 is set to 11, the sub-scanning moving table 22 moves to the right side in the figure. Pulse motor drive circuit 2 for this 6
The pulse signal entering 6 simultaneously enters the U terminal of the counter 40, and the contents of the counter 40 are counted up.

When the contents of the counter 40 become the same as the contents of the latch circuit 37, a match signal from the minus number circuit 39 is outputted, passes through the OR gate 32, enters the R terminal of the flip-flop 70, and sets the output of the flip-flop 34 to Q=O.

Set to Q-1. When Q=O, the computer 42 sets the signal line 43 to "o" to stop the sub-scanning moving table 22. Next, the computer 42 sets the contents of the return position of the specification data in the latch circuit 36. The reset terminal R is driven to set the moving direction of the sub-scanning movable stage 22 to the left side in the figure.

The output of the flip-flop 34 is always Q=O and Q=1, indicating that the sub-scanning movable table 22 is fast-forwarded. Therefore, the computer 42 sets the signal line 43 to 11", and the sub-scanning moving table 22 starts moving to the left side in the figure. At this time, the pulse signal entering the pulse motor drive circuit 26 is simultaneously sent to the counter 4.
When input to the D terminal of 0, the contents of the counter 40 are counted down. - When the contents of the counter 40 become the same as the contents of the latch circuits 36, a match signal from the match circuit 38 is output and input to the set terminal S of the flip-flop 34, causing the output of the 7-lip-flop 34 to become Q=1. Set Q=o. calculator 4
2 turns the signal line 43 to O'' when Q=1 and stops the sub-scanning movable table 22.

Since no continuation data is specified in the specification data, the computer 42 determines that all recording operations have been completed.

As explained above, according to the recording apparatus of the present invention, the control means is provided in front of the image data consisting of image information, into which the recording data having specification data for setting the recording conditions of this image information is input. Therefore, based on the content of the specification data, recorded information such as newspaper pages can be divided and recorded. Therefore, it is possible to extend the editing end time of newspaper articles and include the latest information. , there is no need to store data for the entire page, and the capacity of the device can be reduced.
