〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention.
1, 2, and 13 to 15 are exactly the same as the above-mentioned conventional device. Reference numeral 3 designates a touch panel equipped with a coordinate input function, which is attached to the CRT surface of the graphic display device 1 and made of a transparent material, and 12 is an AD converter.

FIG. 2 shows an example of the structure of the touch panel 3 attached to a CRT display surface. 4 is the glass on the CRT surface, 5 is a resistive film made of a transparent material and uniformly deposited on the entire surface of the glass, 6 7 is a transparent hard plastic sheet that has excellent abrasion resistance and maintains a constant distance from the resistive film 5; 7 is a spacer that insulates between the resistive film 5 and the plastic sheet 6; 8 is transparent glass on which the resistive film 5 is deposited; 9 is a conductive film made of a transparent material provided on the inner surface of the plastic sheet B.

The resistive film 51C is deposited so that the surface of the glass 8 has a uniform resistance value.A voltage is applied to both ends of the resistive film 5 alternately in the X direction and υ゛Y direction on the surface where the resistive film 5 is formed. In the X direction of the surface on which the film 5 is formed, there is a voltage gradient from right to left, and similarly in the Y direction, a voltage gradient occurs from top to bottom. The area on the glass surface of the glass sheet 6 where the resistive film 5 is vapor-deposited is an effective pressing area, and when any position within this area is pressed, the conductive film 9 of the plastic sheet B comes into contact with the resistive film 5. hand,
The conductive film 9 alternately detects voltages in the X direction and the Y direction at the contact position.

The detected analog voltage is quantized in the graphic processing device 2 and converted into a digital signal, which is then taken into the computer as pressed position coordinate data. When the pressure is stopped, the plastic sheet 6 returns to its original state, and the conductive film 9 and the resistive film 5 are insulated. Since the resolution is also excellent, the attachment of the touch panel 3 to the CRT display surface does not cause problems with brightness or parallax when the operator 15 views the CRT display image.
Since the touch panel 6 can be pressed while viewing the displayed image, the corresponding position on the CRT display image can be selected correctly.

FIG. 3 shows another example of the structure of the touch panel. In this example, C
Since the transparent glass 8 provided in front of the RT display screen has the same structure as in FIG. 2 except that it is flat, it can perform the same operations and the same functions as the touch panel 3 shown in FIG. Therefore, a structure is obtained in which the touch panel 3 can be attached to and detached from the graphic display device 1.

In the interactive CAD input/output device configured as described above, the touch panel 6 is a CRT of the graphic display device 1.
Since it is attached to the display surface and has a groove bottom made of transparent material, it does not obstruct the view of the displayed image on the graphic display device 1 and has sufficient resolution, allowing the operator 15 to view the displayed image on the graphic display device 1. By pressing a predetermined position on the touch panel 30 while viewing the screen, the coordinates of the pressed position can be read and added to the CAD as a selected position.Using this action, it is possible to read the coordinates of the pressed position and add it as a selected position in the CAD. A command menu is stored in advance in the graphic processing device 2, and the command menu is displayed on the CRT screen of the graphic display device 1, and the corresponding touch panel 6 of the command menu to be selected is displayed.
When you press the position, a command is selected and its contents are executed.

0 When entering characters, symbols, and numbers, display the keyboard pattern shown in Figure 4 - Keyboard button example on the CRT screen, and press it on the touch panel 3 corresponding to the characters, symbols, and numbers to be written in the figure. It can be carried out.

(Regarding the processing of figures on the IcRT screen, accurate recognition is achieved by specifying the relevant processing position and pressing the element position of the content to be processed with a pen-like object having a protrusion.

When information such as errors and processing results caused by the execution of 0CAD is to be transmitted as a message to all operators, it is displayed in one corner of the CRT display screen, regardless of the operation of the touch panel B.

When performing the above operations, menu sheets related to information on commands related to various graphic creations and selection display information such as keyboard patterns for selecting writing contents such as letters, symbols, and numbers are stored in the graphic processing device 2. . Information to be displayed on the CRT screen can be selected by pressing a predetermined position lt on the touch panel 3 attached to the CRT screen of the graphic display device 1. When creating a figure, display the menu sheet and select the command to be executed using the touch panel 6. When adding elements to the figure, or when recognizing elements on the figure display, press the touch panel 3 at all indicated positions. When specifying and writing letters, symbols, and numbers on figures on the CRT screen, display a keyboard pattern as shown in Figure 4 on the CRT screen, and press the touch panel B corresponding to the letters, symbols, and numbers to be written. Press the position.

As described above, a desired figure can be created by sequentially and repeatedly performing various operations related to figure creation.

According to the present invention, the operator 15 directly observes the graphics displayed on the graphic display device 1 and
The touch panel 3 attached to the RT display screen is superimposed on the graphic information displayed on the CRT screen, and sometimes only a part of the graphic information screen is used to display the graphic information while changing the position of the information to be selected. Since shapes are created by sequentially pressing the touch panel 3, you can easily create designs by simply operating the touch panel 3, with the feeling of creating design drawings directly on the operating table.
It can be executed while interacting with the graphics displayed on the RTCRT screen, reducing erroneous operations and enabling more efficient work.

By depositing the resistive film 5 of the touch panel 3 directly on the CRT glass surface of the graphic display device 1, graphic information can be selected more accurately.

In addition, since the configuration of the CAD input/output device is simplified in the present invention, it is easier to operate the CAD input/output device by installing the graphic display device 1 on an inclined panel such as an inclined drawing board (product name "Drafter"). Work efficiency will improve.

〔Effect of the invention〕

As explained above, the present invention has a simple structure in which a touch panel with excellent resolution and light transmittance is attached to the CRT display surface of a graphic display device, which greatly simplifies the configuration of an interactive CAD people tracing device. 2) Since a transparent touch panel can be placed overlapping the displayed figure on the CRT screen of the graphic display device, the operation of the touch panel becomes extremely easy, and all operations necessary to create figures can be performed only by operating this touch panel. Since the execution results are also displayed on the CRT screen, the objects of attention and operations are limited to the CRT screen of the graphic display device. Furthermore, if this device is installed on a tilted panel whose angle is variable, a good working posture can be selected, making the work of creating figures easier and improving work efficiency. Furthermore, since the configuration of this device is simplified, there is an effect that costs can be reduced.
