Abstract

PURPOSE:To perform plotting while observing the whole of a large size drawing by displaying a graphic with a plane display just underneath the plane display. CONSTITUTION:A graphic input function is attached on an X-Y plotter by providing a panel 17 provided with the plane display 18, ten keys 21, and a function key 22, and graphic input is performed while plotting the graphic with an X-Y plotting function. The panel 17 can be moved manually along a feed screw 14 in a direction of Y, and it is also moved to an arbitrary position on paper 7. The position in the direction of Y of the panel 17 can be detected on a Y-axis moving mechanism. Signals detected with linear encoders 10, 15 and sensors 11, 16 are sent to a panel position detecting part 3, and information detected at the part are sent to a plane display display control part 4 and a main control part 1. The plane display display control part 3 controls the position of a display graphic on the plane display.

[Industrial Application Field] The present invention relates to a graphic input device with an The present invention relates to a graphic input device with XY blocks that eliminates restrictions on the display range and allows drawing work to be performed while viewing the entire large drawing.

[Problem to be solved by the invention]

The conventional methods mentioned above had the following drawbacks. That is, since conventional graphic input devices display graphics using a CRT, the display range of graphics is limited to the size of the CRT screen.

For example, in the current RT display in CAD, a 30-inch CRT is normally used, and the display range of graphics is narrow.

This makes drawing work difficult, and when drawing while looking at the entire figure, it is especially difficult to see and the eyes get tired.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate such conventional drawbacks, to substantially eliminate restrictions on the graphic display range in a graphic input device with an XY plotter, and to enable drawing work to be performed while viewing the entire large drawing. shall be.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle of the present invention, and the principle of the present invention will be explained below based on this diagram. In the figure, l is the main control unit, 2 is the memory, 3 is the panel position detection unit, 4 is the flat display display control unit, and 5 is the XY
This shows the block control part. Also, 6 is a flat board of the XY plotter, 7 is paper, 8 is a feed motor in the X direction (X-axis direction), 9 is a feed screw in the X direction, 10 is a linear encoder in the X direction, and 11 is a position detection in the X direction. l2 is the Y-axis moving mechanism, l3 is the Y-direction (Y-axis direction) feed motor, l4
is a feed screw in the Y direction, 15 is a linear encoder in the Y direction, 16 is a sensor for position detection in the Y direction, 17 is a panel, 1
8 indicates a flat display, and 19 indicates a pen.

The panel l7 can be manually moved linearly in the Y direction along the Y-direction feed screw 14, and the Y-axis moving mechanism 12 can be manually moved along the X-direction feed screw 9. It looks like this.

Therefore, the flat display 18 provided on the panel 17 can be manually moved to any position on the paper 7 placed on the drawing table 6 (freely movable in the X and Y directions) 7 Encoders 10 and 15 and sensors 11 and 16
The signal from the panel 1 is sent to the panel position detection section 3, and the signal from the panel 1
7 positions are detected (these lO, l5, l1, 16
, 3 constitute a position detection means). The memory 2 stores drawn graphic data.

Also, the XY plotter control section 5 controls the motors 8 and 13 based on the graphic data in the memory 2, and plots on the paper 7 using the bevel 19.

The flat display display control unit 4 performs lJ[I to display data in the memory 2 based on the position information from the panel haze detection unit 3. In this case, the flat display 18 always displays the figure on the paper 7 directly below it.

When the moving star (Ax, Ay) of the flat panel display I/I 18 is detected by the panel position detection section 3, this detection signal is sent to the flat display display control section 4 and the main control section 1.

As a result, the display is constantly fed back and displayed so that the position of the display content on the flat display is moved by an amount opposite to the amount of movement of the flat display I/I.As a result, even if the flat display 18 is moved, Since the figure directly below the flat display 18 is always displayed, you can see it on the flat display 18 as if you were looking at a figure written on paper. When drawing and inputting figures are performed while viewing such a display, this figure data is stored in the memory 2. [Function] Since the present invention is configured as described above, it has the following effects.

The flat display display control unit 4 controls the position of the displayed figure on the flat display based on the above information. In this case, the GL control is constantly controlled in a closed loop, and graphic data to be displayed is retrieved from the memory 2, and these operations are controlled based on commands from the main control section 1. The numeric keypad 21 and function keys 22 are used when inputting figures, etc. For example, when adding a new figure to a previously drawn figure, while looking at the display screen, press the Use the keys to input figures.

When the XY plotter control section 5 retrieves data stored in the memory 2 and draws a diagram on paper 7, it controls the feed remoters 8 and 13 based on instructions from the main control section 1.

Assume that the XY plotter control unit 5 plots a figure as shown in (A) using the figure data in the memory 2. At that time, (B) is displayed on the display screen of the flat display 18.
Displays the figure directly below, as in . As a result, you can see the figure on the display screen as if you were looking at a figure drawn on paper 7. Also, as shown in (C), panel 1
When you move 7, the position of the displayed figure moves by the same amount in the opposite direction, and it is displayed as if part of the figure on the paper is being viewed through a flat display. In this way, while looking at a large area of paper, it is possible to draw a figure by viewing parts of the figure on the flat display as needed.

In this case, it is easy to select graphical units (lines, circles, etc.) and specify areas, so it can be created in the same way as when using a conventional CRT. Furthermore, by enlarging the display on a flat display using a lens or the like, it is possible to create or modify minute figures.

However, in this case, the amount of movement of the figure on the flat display is the magnification factor multiplied by the amount of movement of the panel in the opposite direction.
Become. In the above embodiment, an example was described in which the numeric keypad 21 and the function keys 22 are mounted on the panel 17 together with the flat display 18, but the present invention is not limited to such an example. It is also possible to separate the function keys from the flat display and use it as a separate device. In this case, the numeric keypad and the function keys may be connected to the planar board by, for example, a cord, or may be attached to a part of the planar board.

′ [Effects of the Invention] As explained above, the present invention has the following effects.

(1) The area of the figure to be drawn can be enlarged, AO size or larger is also possible,
Unlike in the past, there is no restriction by the size of the CRT screen.

Therefore, it is possible to create detailed figures while looking at the entire large figure.
