Description

[Detailed explanation of the idea] The present invention relates to a display device in a phototypesetting machine.

In recent years, display devices for phototypesetting machines that are equipped with an imaging unit CRT such as a vidicon CCD or a display unit such as a plasma display are being developed.

On the other hand, the size of characters that can be printed with so-called manual phototypesetting machines generally varies from 7Q (1.75mm square) to 100Q (25mm square), and these various sizes of characters can be printed. It is said to be extremely difficult to reproduce them simultaneously on a unit.

In other words, characters of about 100Q can be displayed without any problems, but only a few scanning lines can be assigned to small characters such as 7Q and 8Q (2 mm square), and there is no hope of modification to the extent that they can be identified as characters. .

On the other hand, if small characters such as these are enlarged at a certain rate so that they are assigned a sufficient number of scanning lines to be discernible, large characters will also be enlarged at the same rate, which will reduce the display area of the display unit. This will lead to huge growth.

In order to deal with this situation, the size of the characters actually printed on the photosensitive material (the number of characters printed) is reproduced on the display unit at a uniform size, and the printing interval of each character on the photosensitive material is A method is adopted in which the pitch is displayed on the display unit at a constant pitch, regardless of the amount of feed.

FIG. 1 shows an example of such a display, where 1 is the display surface of the display unit, and 2 is the display character.

However, if such expedient measures are taken, there arises a problem that the actual printed content cannot be intuitively assumed from the displayed content on the display unit.

For example, even if the actual printed content is two types of characters, large and small, as shown in Figure 2, when displayed on the display unit, it will be a fixed size as shown in Figure 1, and the displayed content in Figure 1 It is obvious from this that it is difficult to recall the printed content in Figure 2.

The present invention has been developed in view of these points, and provides a display device for a phototypesetting machine that can display images in arbitrary sizes and pitches on a display unit, and also allows easy recall of the actual printed content. be.

Therefore, the present invention includes a display unit that images the characters stored on the dial using the imaging unit 15 and displays the image in an arbitrary size; a section that detects the magnification of the variable magnification lens; and a numeric pattern that represents the magnification of the variable magnification lens. Pre-stored memory; and imaging/display in which a numerical pattern corresponding to the detected magnification of the variable magnification lens is read out from the memory, transferred to the display unit I, and displayed together with the character image taken from the dial. It is characterized by consisting of a control circuit.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 3 shows display contents in one embodiment of the present invention.

Note that the actual printed content is as shown in FIG.

In FIG. 3, the number 3 below the display character 2 indicates the actual number of printed Q of the corresponding display character, and the number 3 below the display character
The number 4 displayed in between indicates the amount of feed when printing each character.

Here, if the same print Q number 3 and feed amount 4 are consecutive, only the first one may be displayed and the remaining ones may be omitted unless there is a change.

What is shown as 5 is also a display of the feed amount, but it is a display of the horizontal feed amount and the vertical feed amount side by side. In the example shown in the figure, "56" is the horizontal feed amount and "40" is the vertical feed amount. The relationship is the directional feed amount.

Here, the display positional relationships between the displayed characters 2, the number of printed Qs 3, and the feed amounts 4 and 5 are not limited to the relationships shown in the diagram.
For example, a comment area may be provided in a part of the display screen, and the number of print Qs of 3 and the feed amount of 4 and 5 may be displayed all at once in the area, or the units of Q and H of the number of print Qs of 3 and feed amounts of 4 and 5 may be displayed. may be written together with each numerical value.

Alternatively, only one of the number of print Qs (3) and the feed amount may be displayed, or the screen may be alternately switched and displayed.

Next, an embodiment of the device of the present invention that realizes such display contents will be explained based on FIG. 4.

6 is a dial containing various characters and symbols, 7 is a light source, and 8 is a variable magnification lens.

Although only one variable magnification lens 8 is shown for convenience, in reality, a plurality of variable magnification lenses 8 are mounted, for example, on a turret, so that the variable magnification lens 8 having a desired magnification can be inserted into the optical path as appropriate.

9 is a shutter, 10 is a travel lens system, 11 is a driving source for driving the travel lens system 10, and 12 is a sensitive material which is housed in a magazine 13 in a light-tight manner.

Reference numeral 14 denotes a drive source for rotating the drum around which the photosensitive material 12 is wound.

These components are conventionally known components of phototypesetting machines, and can be freely replaced with or added to various other known components.

Reference numeral 15 denotes an imaging unit which images a character image using a light beam divided by an optical path splitting means M such as a mirror or prism inserted into the optical path.

In the present invention, since the displayed characters are displayed in an arbitrary size, instead of capturing an image after converting the magnification of the character image on the dial using the variable magnification lens 8, the imaging unit is placed at position A shown by the dotted line in the figure. It is also possible to set up and take images.

The character image captured by the imaging unit 15 is displayed as a character of an arbitrary size on the display unit 16, which will be described later.
Since the specific method is well known, its explanation will be omitted here.

17 is an imaging display control circuit, and 18 is a control circuit for the drive source 11.14 which stores the current printing position on the photosensitive material 12 and drives the drive source 11.14 as appropriate in accordance with the feed amount command.

Reference numeral 19 denotes a CPU, which includes a memory in which various numerical patterns representing the number of printed characters 3 and feed amounts 4 and 5 to be displayed on the display unit 16 are stored.

Next, the operation will be explained.

First, the operator sets the variable magnification lens 8 in order to obtain printed characters of a desired size.

Then, the CPU 19 detects the magnification of the set variable magnification lens 8, reads out a numerical pattern corresponding to the magnification from the memory, and sends it to the imaging display control circuit 17.

At the same time, the feed amount corresponding to the magnification of the variable magnification lens is calculated, and the feed amount corresponding to the number of printed Qs is transmitted to the drive source control circuit 18.

In particular, if the feed amount is specified, no calculation is necessary and the specified feed amount is transmitted to the drive source control circuit 18.

This calculated feed amount is C as the corresponding numerical pattern.
It is read out from the memory of the PU and sent to the imaging display control circuit 17 as a pattern of corresponding feed amounts 4 and 5 to be displayed on the unit 16.

On the other hand, the operator picks up the characters to be printed from the dial 6, brings them to the optical axis position, and fixes the dial 6.

If this fixed signal is given to the CPU 19 as an imaging start signal for the imaging unit 15, a video signal of a desired character image can be obtained.

Then, the print Q is first transferred to the imaging display control circuit 17.
It is combined with the numerical pattern of number 3 and feed amounts 4 and 5 and displayed on the display unit 16 to obtain the display contents as shown in FIG.

Note that in the case of so-called blank printing, in which printing is not actually performed, only the numerical patterns of feed amounts 4 and 5 and the number of prints Q are displayed.

Further, if the command to open the shutter 9 is used as a command to start imaging the imaging unit 15 or a video signal transfer command, the above-mentioned display contents can be obtained only for the characters actually printed on the photosensitive material 12.

Furthermore, the display contents can include not only the number of prints Q and the amount of feed, but also the deformed shape, deformation rate, amount of padding at the time of padding printing, or remaining staff.

Of course, it is clear that the numerical patterns representing these also include symbols based on certain conventions.

Also, in the above explanation, the display is performed at any size and pitch regardless of the lens magnification, but for example, the lens magnifications 1Q to 24Q are displayed as n, 28Q to 44Q as nl, 5
0Q~100 Display unit 1 with Q as the size of n2
6 may be displayed.

As mentioned above, in the display device of the present invention, the displayed characters can be displayed in any size and pitch, and the actual number of printed Qs, feed amount, etc. can be displayed at the same time in correspondence with the displayed characters. The purpose of this invention is to make it easier for an operator to remember the actual printed content from the displayed content, and to provide an inexpensive and highly effective display device.
