Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monitor device for a phototypesetting machine, and more particularly to a monitor device equipped with a reference line display function that is useful when monitoring line head and line alignment typesetting. .

A monitor device for a phototypesetting machine is used to monitor the characters that have been printed on the photosensitive material, the characters that have been blank printed (hereinafter all will be explained as blank printing), or the characters that are about to be blank printed. A display device that can display information corresponding to the printing state has already been proposed.

First, as a background explanation of the present invention, the display state of -471 on these character image confirmation monitor devices is shown in FIG.
This will be explained with reference to FIG.

FIGS. 1 and 2 are diagrams showing how the relative relationship between the printing state on the photosensitive material 1 and the display state on the monitor display section 2 changes as the blank printing operation progresses. In the figure, white characters are characters that have already been blank-printed but are not displayed on the display, black characters whose interior has been filled in are characters that have been blank-printed and are displayed on the display, and diagonal characters are characters that have been blank-printed and are not displayed on the display. Next, the position is freely moved for blank printing to indicate each display character in the layout.

Furthermore, differences 51 and 52 between the reference position of the photosensitive material 1 shown by the broken line 3 and the reference position of the monitor display section 2 shown by the broken line 4 indicate which position on the photosensitive material 1 is being displayed. For example, in the state shown in Figure 1, after blank printing of the character "ME" is completed, by increasing the scroll amount by △s, the next character "ME" can be printed as shown in Figure 2.
It is now possible to deal with the layout of the By the way, the monitor display as shown in Figures 1 and 2 above certainly makes it possible to easily grasp the mutual positional relationship between adjacent characters, and is extremely effective in so-called "close printing". However, it has been impossible to intuitively grasp the absolute positional relationship of each character shape with respect to the photosensitive material 1 itself.

Therefore, for example, as shown in FIG. l5
The above-mentioned character confirmation monitor device could not satisfactorily meet the demand for alignment typesetting, etc., in which desired characters are printed in a well-balanced manner between the Q spaces.

The present invention has been achieved in order to solve these problems in monitor devices for phototypesetting machines and to contribute to more typesetting processes specific to phototypesetting, and will be described below based on embodiments.

FIG. 4 is a schematic diagram showing an embodiment of a phototypesetting machine incorporating a monitor device according to the present invention, in which a light source 5, a dial 6, a main lens 7, a deformable lens 8, a collimator lens 9,
The configuration of the phototypesetting machine, including the reflecting mirror 10, shutter 11, moving optical system 12, sensitive material drum 13, print position control circuit 14, horizontal feed and vertical feed drive circuits 15 and 16, etc., is conventionally known.

Further, 17 is an optical system for photographing monitor characters, 18 is an image pickup tube,
19 is a character display control section, 20 is a monitor display section consisting of a cathode ray display tube, etc., 21 is a deflection control circuit, 22 is a line display control section, 23 is a typesetting condition setting section, 24 is a deflection position synchronization signal, and 25 is a scroll amount. The change signal 26 is a scroll amount signal, and the monitor device according to the present invention is designated by number 2 in the figure.
This relates to the part indicated by 7. In addition, the above numbers 5~
The configurations marked with 17 are merely examples, and it goes without saying that the apparatus of the present invention can be applied to phototypesetting machines with various other configurations. FIG. 5 shows the monitor device 2.
FIG. 7 is a configuration diagram more specifically showing an example of 7.

In FIG. 5, the line display control section 22 includes a line signal generation circuit 28 and a line position address command circuit 29.
, a scroll amount signal generation circuit 30, and the formesetting condition setting section 23 includes a line start position setting register 31, a line end position setting register 32, a formesetting direction selection switch 33, and a formesetting format selection switch 34.

Next, the relationship between the specific operation of the line signal generation circuit 28 and the display state on the monitor display section 20 will be schematically explained based on FIG. 6.
37 are horizontal and vertical deflection position counters that output signals that follow the deflection position on the monitor display unit 20 by receiving the deflection position synchronization signal 24;
and 38 are horizontal and vertical line display registers for setting data at externally commanded addresses.

Also, the data set states in the registers 37 and 38 are shown with diagonal lines. The signals read from the line display registers 37 and 38 using the contents of the deflection position counters 35 and 36 as read addresses are output to the set/reset type FFs 39 and 40, respectively.

Therefore, the FFs 39 and 40 have widths Δw and v1 to v1 in the figure.
As a result of outputting signals corresponding to the sections of V2 and transmitting the logical product of these two signals to the display section 20 via the AND circuit 41, a vertical line display as shown by number 42 is obtained on the display section 20. It will be done.

That is, as is clear from the above explanation, the line signal generation circuit 2 generates an address signal corresponding to the position of the line to be displayed.
8, a desired line display can be obtained on the display section 20.

Although the above is a case of vertical line display, it is also possible to obtain a horizontal line display as shown in FIG. 7 by appropriately changing the address commands for writing data to both registers 37 and 38. Furthermore, although the examples in FIGS. 6 and 7 show cases in which one pair of line display registers 37 and 38 are provided, in other embodiments, two pairs of line display registers are provided, and one If one pair is used to display horizontal lines and the other pair is used to display vertical lines, it is possible to display horizontal and vertical lines at the same time. Next, the line position address command circuit 29 in FIG. 5 is a circuit that outputs an address command signal to the line signal generation circuit 28, and 43 and 44 are the position V in FIGS. 6 and 7.
This is a register in which values corresponding to l, v2 and Hl, h2 are set in advance, and 45 is an arithmetic switching circuit.

The arithmetic switching circuit 45 inputs the scroll amount signal S obtained as described later, the line start position signal a1 and the line end position signal A2 sent from the setting registers 31 and 32, and outputs "a1-S", " a1-S-△W” “A2-S”
Four types of signals β, "A2-S+Δw", are outputted at once. Therefore, when the typesetting direction selection switch 33 is selected to the "horizontal" side, the four types of signals β are supplied as address signals to the horizontal line display register 37 via the AND circuit 46, and
The values of v1 and V2 set in the register 43 are instructed to the vertical line display register 38 via the AND circuit 47. Similarly, when the formatting direction selection switch 33 is set to the "vertical" side, the four types of signals β are supplied to the vertical line display register 38, and the values of h1 and H2 are commanded to the horizontal line display register 37. That will happen. In addition, as a special case, when the signal A3 from the variable setting register 48 is input to the arithmetic switching circuit 45, "A3-s" and [A3-s-ΔW] or "A3-
The signal “S+△w” becomes the output signal β. Next, to explain the scroll amount signal generation circuit 30 in FIG. 5, numeral 49 is a counter that outputs the scroll amount signal S. First, the input signal γ is set as an initial value, and then,
It follows the value δ of the scroll amount change signal 25 sent from the character display control unit 19 and outputs a signal S=γ+δ.

Furthermore, 50 and 51 are setting counters, and the meanings of the values "a" and "b" set therein will be clarified in the later explanation related to FIGS. 8 and 9. By the way, as is clear from the specific configuration example of the scroll amount signal generation circuit 30 shown in FIG.
The relationship between the various setting conditions and the signal γ is as shown in the table below.

Therefore, the relationship between the four types of signals β output from the arithmetic switching circuit 45 and the formatting conditions is as follows. Incidentally, in the table below, only the case of horizontal typesetting will be explained, but it goes without saying that the operation is similar in the case of vertical typesetting.

Based on the four types of signals β, a predetermined address signal is outputted from the line position address command circuit 29 to the line signal generation circuit 28 as described above.

8 and 9 show the relationship between the data set states of the horizontal and vertical line display registers 37 and 38 and the display state on the monitor display unit 20 when δ=0, that is, the initial row schedule, as shown in FIG. They are schematically shown as an example, and FIG. 8 shows the case of forward feed format, and FIG. 9 shows the case of reverse feed format.

In FIGS. 8 and 9, the line display 42 shown with diagonal lines indicates that it is not displayed under the initial conditions, but 1a2
-Depending on the value of All, two lines may be displayed at the same time.

Further, the value δ of the scroll amount change signal 25 increases in the positive direction in the case of the forward feed format, and decreases in the negative direction in the case of the reverse feed format.

Therefore, as the blank printing operation progresses, the character display control section 1
When the scroll amount change signal 25 is sequentially sent from 9, the line display in FIG. 8 immediately moves to the left (on the drawing),
The line display in Figure 9 will move to the right. Finally, a line display 42 indicated by diagonal lines is displayed on the monitor display section 20. Furthermore, Figures 8 and 9
Although the display of character images is omitted in the figure, it goes without saying that appropriate character images can be displayed in a superimposed manner by the operation of the character display control section. It goes without saying that during scrolling, these line displays and character displays move without changing their relative positions. As is clear from FIGS. 8 and 9, in the present invention, when the formatting format is in the forward direction, at least a line display corresponding to the beginning of the line appears on the left side of the display section 20, and when the formatting format is in the reverse direction, In this case, at least a line display corresponding to the end of the line is displayed on the right side of the display section 20, and furthermore, in the case of the forward direction format, a line display corresponding to the end of the line is displayed at an appropriate point during the blank printing operation. , and in the opposite direction, a line display corresponding to the beginning of the line can be obtained.

Therefore, the scroll amount signal S is transmitted to the character display control section 19.
If the line display and the character display are associated so as to show the same positional relationship by supplying the line display to the line display, it becomes possible to freely layout the character positions using the line display as a guide. Incidentally, as is clear from FIGS. 8 and 9, the value "a" set in the setting counter 50 corresponds to the first line in the forward direction format under the initial condition, that is, when δ=0. This is a value for setting the difference between the display (FIG. 8) and the line end line display in reverse format (FIG. 9). Next, the variable setting register 48 will be briefly explained.

The variable setting register 48 is used to immediately display a line at any position on the monitor display section 20 where several characters are displayed, and the setting value can be changed. Therefore, the position of the line display can be moved. Therefore, if the line display is moved as appropriate and the set value when it reaches the desired position is set in the line start or line end position setting registers 31, 32, typesetting as shown in FIG. 10 can be easily processed. It becomes possible. In yet another embodiment, by simultaneously displaying the line start/end line display described above and the arbitrary position line display using the variable setting register 48, the following usage is also possible. In other words, if a gap occurs between the last character image and the line end line display when blank printing is performed with appropriate positioning,
In other words, if the so-called jostification is not performed as desired, the arbitrary position line display is made to match the line end side of the last character image, and the value of the variable setting register 48 and the line end position at that time are adjusted. By calculating the difference from A2, it is possible to accurately grasp the remaining line length necessary for the adjustment operation. As described in detail above, the monitor device according to the present invention has a line starting position A.
l. A formatting condition setting section 23 in which the line end position A2, typesetting direction, and formatting are set, and a scrolling amount change that is supplied from the outside with an initial value of scrolling amount obtained based on a signal from the setting section. A scroll amount signal generation circuit 3 that outputs a scroll amount signal S obtained by increasing or decreasing the amount according to the signal.
0, the scroll amount signal S, and the line head position Al. A line position address command circuit 29 that commands address signals corresponding to the display positions of the first line and the last line based on each value of the line end position A2, the position commanded by the address signal, and the deflection position on the display section. a line signal generation circuit 28 that outputs a line display signal based on a coincidence signal with the line display signal, and a monitor display unit 20 that displays a desired line start line and line end line using the line display signal as a modulation signal.
By doing so, the present invention makes it possible to intuitively grasp the absolute positional relationship of each character shape with respect to the photosensitive material itself, and it is possible to process various types of typesetting. It has a remarkable effect.
