Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual phototypesetting machine having a monitor display, and more particularly to a phototypesetting machine which saves the memory required for storing character data of the characters displayed on the monitor display. It concerns typesetting machines.

Generally, in a phototypesetting machine having a monitor display device, as shown in FIG. is displayed as shown in Figure 2.

In FIG. 2, 5A is the display surface of the monitor display device 5, and C is the displayed character. After confirming the character type, printing position, etc. on this display surface 5A, printing is performed on a sensitive material (not shown). On this occasion,
The characters imaged by the imaging means 2 and digitized by the digitizer 3 are stored in a memory (not shown) each time they are printed, and eventually all printed characters are stored.

For phototypesetting machines with a monitor display, 1
Since the display position of the character currently being marked can be freely moved using the position of the character printed before the character as a guide, this method is particularly effective when performing so-called nail printing as shown in FIG.

Normally, when performing nail printing, high display quality is required because the characters that have already been printed and the characters that will be printed are displayed on a monitor to visually confirm the positional relationship such as the proximity of both characters. be done. In particular, characters with thin strokes, such as characters in the Mincho system, are required to have high display quality because the thin parts may be blown out during digitization.

Therefore, the monitor display device of a phototypesetting machine is usually equipped with a device with a high resolution, and the amount of data for the digitized characters to be displayed inevitably increases, and in the end the printed characters A large capacity memory is also required to store the character data.

Therefore, with conventional phototypesetting machines, as mentioned above,
Since a large amount of data must be stored for each printed character, the amount of memory required to store the character data of the characters that have already been printed becomes enormous, making the device larger and more expensive. This led to price increases.

The present invention has been made from these points,
The memory capacity for storing character data for monitor display is as small as possible, and even in that case, the same display quality as before can be obtained for characters printed n (n≧1) characters before the character being typed. The purpose of this product is to provide a phototypesetting machine that can digitize characters captured by an imaging means in a phototypesetting machine equipped with a monitor display device. n+1 digitizing storage units each store character data of characters and characters printed up to n (n≧1) characters before the character being typed, and the character data stored in the digitizing storage units are a reduction means for reducing character data to a smaller number; a page memory for storing character data of characters printed before n+1 characters reduced by the reduction means; an enlarging means for enlarging data to a size approximately equal to the size before being reduced by the reducing means; character data enlarged by the enlarging means;
and a refresh memory for monitor display into which the character data stored in the n+1 digitizing storage sections is written.

A page memory control unit 32 controls the page memory 31, and controls the storage position, readout position, etc. of character data. 33 is a character generator that generates characters for displaying various messages on the monitor display device 5; 34 is a character generator control unit that controls the character generator; and 35 is a character generator controller that stores information to be displayed on the monitor display device. 36 is a refresh memory control unit that controls the refresh memory 35; 37 is a parallel-to-serial (P/S) conversion circuit; This is a reduction circuit that converts and outputs the data into a different form, and reduces the amount of data per character by, for example, thinning out character data.

Reference numeral 39 denotes an enlargement circuit for enlarging the character data read out from the page memory 31 for display on the monitor display device 5, and the enlarged data is sent to the refresh memory 35. The enlargement process is performed by, for example, interpolation or the like.

Next, the operation of the present invention will be explained. First, the input section 28
Lens magnification, feed pitch, length of one line, vertical/
Commands for various formatting conditions such as horizontal writing are sent to the control section 29, and the data is stored in the data storage section 30.
Based on this stored data, the main lens 9 and deformable lens 10 are set as desired.

The operator selects a desired character from dial 1 and sets it at the character position. Then, from the input unit 28, a command is given to the monitor display device 5 to display the transcribed characters on the monitor. Then, the main lens 9,
The character image that has passed through the optical system such as the deformable lens 10 is captured by the imaging means 24, further digitized, and stored in the digitized storage section 26-1 via the S/P conversion circuit 25. Digitization storage section 26
The contents of -1 are transferred to the refresh memory 35, passed through the P/S conversion circuit 37, and displayed on the display surface 5A of the monitor display device 5 as shown in FIG. Note that the digitized character data at this time is character data with a large amount of data and has display quality sufficient to withstand even when simulating nail printing or the like on a monitor display device. At this time, the control unit 29 controls the calculation unit 23, current position counter 22, The travel system 16 and the sensitive material drum 18 are controlled to be driven by the drive sources 19 and 20 via the feed control circuit 21.

The operator looks at the monitor display, confirms the character type, character size, print position, etc., and then presses the input section 2.
A command to print is issued from 8. Then shutter 1
3 is operated and the characters are printed on the photosensitive material 17.

The display state of the monitor display device 5 at this time is as shown in FIG. 5. Here, the state of the character "love" is different in Figure 5 1 and 2, but the one with the inside blank as shown in Figure 5 1 is being typed and is not yet printed on the photosensitive material. If the inside is filled out as shown in FIG. 52, it means that it has already been printed on the photosensitive material. For convenience, the illustrations have been changed to make it easier to distinguish between the two, but in reality, both are generally displayed on a monitor display with their interiors filled in as shown in Figure 5-2. It is.

Next, the operator selects, for example, the character "no" from the dial 1, sets it at the font position, and issues a command from the input unit 28 to display the character on the monitor.

Then, the image is captured by the imaging means 24 in the same manner as described above, and then digitized and stored in the digitized storage section 26-2 via the S/P conversion circuit 25. The contents of the digitizing storage section 26-2 are transferred to the refresh memory 35, and sent to the monitor display device 5 via the P/S conversion circuit 37 as shown in FIG. Displayed on the monitor at the same time as the characters “love”.
After confirming the status displayed on the monitor, the operator issues a command to print from the input unit 28 as described above. Then, the contents of the digitized storage section 26-1 (the characters for "love") are thinned out in the reduction circuit 38, converted into character data with a small amount of data (i.e., small characters), and transferred to the page memory 31. and stored in a predetermined position under the control of the page memory control unit 32. At this stage, the character data for the character "love" in the digitized storage section 26-1 is erased.

Next, under the control of the page memory control unit 32, data to be displayed on the monitor display device 5 is read from a predetermined position in the page memory 31. In this case, the character data portion of the character "love" is read out. The read character data is sent to the enlargement circuit 39 and enlarged, and then sent to the refresh memory 3.
Transferred to 5. The enlarged size at this time is approximately the same as the size before the character is reduced by the reduction circuit 38. However, the quality will not be exactly the same as before the reduction, but will be somewhat degraded.

The enlarged character data transferred to the refresh memory 35 passes through the P/S conversion circuit 37 and is displayed on the monitor display device 5 as shown in FIG.
characters are displayed. In FIG. 5, the character "love" is shown with diagonal lines, but this is also for convenience; This indicates that the characters are displayed by enlarging the data again. As described above, the character "AI" displayed at this time is of lower quality than the character "AI" displayed in FIG. 52.

Next, the character "A" is selected from the dial 1, set at the font position, and a command is issued from the input section 28 to display it on the monitor. After the character image is captured and digitized in the same process as described above, it is stored in the digitization storage section 26-1, transferred to the refresh memory 35, and then transferred to the P/S conversion circuit 37.
After that, the image is displayed on the monitor display device 5 as shown in FIG. Although the display quality of the character "love" in Fig. 5 may be slightly inferior as mentioned above, the character "no"
Since the two characters "A" and "A" are displayed using the character data stored in the digitizing memories 26-1 and 26-2 that have not undergone reduction processing and enlargement processing, the display quality is good. Therefore, it is also possible to move the character "a" displayed on the monitor as appropriate and simulate printing by bringing the character "a" very close to the character "no".

After checking the printing position, etc., when the character "a" is printed, the contents of the digitized storage section 26-2 (the character "no") are converted by the reduction circuit 38 into character data with a small amount of data. The data is transferred to the page memory 31 and stored at a predetermined location in the page memory 31 under the control of the page memory control unit 32 . At this stage, the character data of the character "NO" in the digitized storage section 26-2 is erased. Thereafter, the page memory 31 data is read out and enlarged in the same manner as in the case of the character "love", and the character "no" with a slightly inferior display quality is displayed on the monitor display device 5.

One embodiment of the present invention has been explained in detail above, but the explanation so far has been that only the characters printed one character before the character being displayed on the monitor are displayed with high display quality, and the characters printed before that are displayed with high display quality. , the data per character is changed.
However, the present invention is not limited to this, and it goes without saying that characters printed n (n≧1) characters before can be displayed with high display quality if necessary.

Further, although the illustrated example is in horizontal writing mode, it goes without saying that it can also be implemented in vertical writing mode.

As explained above, according to the present invention, the character being typed and the character printed one character before it are displayed with high quality, but the display quality of the characters printed before that is displayed in a small amount even if the quality is slightly inferior. Since the above-mentioned configuration is based on the basic idea of converting the data into capacity data and storing it, it is possible to reduce the capacity of the page memory that stores character data for display on the monitor. Also, the character being typed and the character printed one character before the character being typed are displayed in high quality, so if the character printed one character before the character being typed is displayed in high quality, as in the case of conventional claw printing, etc. This has the great effect of not affecting the work of checking the positional relationship between characters and the characters being typed.
