Abstract

PURPOSE:To facilitate operation by input a figure directly on the display screen of a display device and immediately reflects the inputted figure on the display surface. CONSTITUTION:A pointing device 2 inputs coordinate values and control information and is connected to a device main body by a connection cable 4. Then, a display part 3 is equipped with a detecting means which detects the coordinate position of a coordinate point indicated with the pointing device 2. The display part 3, therefore, functions to output the coordinate position as an electric signal and also displays the figure with display information for displaying the figure.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drafter device for designing drawings and the like with computer support.

[0002]

2. Description of the Related Art Generally, a device of this type is generally constituted by a pointing device device such as a mouse, a stylus pen and a tablet, a digitizer, etc. as an input device, a numeric keypad device and a display device for displaying drawings. For the creation or correction work of, the pointing device unit inputs the coordinate value and the control information, and the drawing is displayed on the display unit based on this information.

[0003]

In the conventional drafter device described above, the pointing device device for inputting the information and the display device for displaying the drawing are independently configured, and an operator who performs design work by computer assistance. Must operate the pointing device placed aside at the same time while checking the screen of the display device, which requires a skill to perform the work.

Therefore, the present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to directly input a graphic to the display surface of the display device and to input the input graphic. Is to be immediately reflected on the display surface, thereby providing a drafter device that is easy to operate.

[0005]

In order to achieve this object, a drafter device according to the present invention has a pointing device device for inputting coordinate values and control information and a detecting means for detecting the coordinate values, and A display unit is provided for displaying a screen based on the coordinate values and control information input by the pointing device device.

[0006]

In the present invention, since the display unit for displaying the screen is provided with the detecting means for detecting the coordinate value, the coordinate value and the control information are directly inputted from the screen by the pointing device.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a drafter device according to the present invention. In the figure, the drafter device of the present invention is
It comprises a pointing device device 2, a pointing device connecting cable 4, a canvas 1, a display portion 3 and legs 5. The canvas 1 is a work area for performing design work. The pointing device device 2 determines the coordinate points in order to input, correct, and delete lines and points when drawing on the canvas 1, and inputs the coordinate values and performs operations such as input, correction, and deletion. This is a device for inputting control information for instructing.

The display portion 3 is provided with detection means for detecting the coordinate position of the coordinate point designated by the pointing device device 2, and the display portion 3 outputs the coordinate position detected by this detection means as an electric signal. It also has a function of displaying a graphic according to display information for displaying a graphic input from an external device such as a computer device. The pointing device connection cable 4 connects the pointing device device 2 and the device body, and transmits the information input by the pointing device 2 to the device body as an electric signal.

The drafter device of the present invention is constructed as described above, and its operation will be described below. Canvas 1
By moving the pointing device device 2 while contacting it on the surface of the display portion 3 and pointing at the arbitrary point by the pointing device device 2, the coordinate value and control information of the arbitrary coordinate point are input. . The control information input by the pointing device device 2 is transmitted to the device body as an electric signal via the pointing device connection cable 4. The coordinate value recognized on the display portion 3 of the canvas 1 and the control information transmitted from the pointing device device 2 are transmitted together to the computer device according to an instruction from the pointing device device 2.

By repeating the above operation a plurality of times,
In CAD software running on a computer device, figures such as points and lines are defined from a plurality of coordinates and control information obtained by the above operation. Next, in order to display the defined figure as a figure on the display part 3 so that it can be confirmed immediately, the control information for displaying the figure is transmitted from the computer apparatus to the apparatus body as an electric signal, and based on the control information. A graphic defined by the CAD software on the computer is displayed on the display portion 3 of the apparatus main body.

The pointing device unit 2 is directly brought into contact with the displayed graphic to input and correct lines and points,
In order to delete, the coordinate point is determined, and the coordinate value is input, so that operations such as input, correction, and deletion are performed. As described above, since the pointing device device 2 can be operated by directly contacting the display portion 3 of the display device at the same time of checking the screen of the display device, the input operation in the design work becomes easy and no skill is required.

FIG. 2 is an overall perspective view showing a second embodiment of the present invention. The second embodiment shows a desk-top type drafter device, in which the canvas 11 is thickened and the display portion 3 is inclined so that the pointing device device 2 can be easily operated. . The mechanism of the device or the operating method is the same as in the first embodiment.

[0013]

As described above, according to the present invention, since the display unit for displaying the screen based on the coordinate value and the control information input by the pointing device has the detecting means for detecting the coordinate value, At the same time as confirming the screen of the display device, the pointing device device can be brought into direct contact with the portion of the display device on which the graphic is displayed for the input operation, which facilitates the input operation in the design work and reduces the There is an effect that the efficiency of the design work can be improved by reducing operation mistakes without requiring skill.
