JPH02194417A - Cad input device - Google Patents

Abstract

PURPOSE:To improve input efficiency by providing at least a single command switch on the side wall of a stylus pen. CONSTITUTION:Push buttons 1 to 5 such as stop, cancellation and division are added to the shaft part of a stylus pen which a finger makes contact with, and switches 1A to 5A corresponding to the push buttons 1 to 5 are provided inside the shaft part. Consequently when a command indicated by the push button is inputted, since it can be directly inputted through the stylus pen, a keyboard operation or a mouse operation is made unnecessary. Thus since the normal command of a CAD can be selected by a single hand, and further the frequently used command is arranged as the push button, the command such as the division and cancellation can be executed without moving the hand, and the CAD can be inputted at high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a CAD input device, and particularly to a CAD input device that integrates both a mouse and a stylus pen.

[Conventional technology]

Conventional CAD input devices use a stylus pen in the right hand to pick up menus from the screen menu, a mouse in the left hand to assist with input, and when input from the keyboard is required. He took his hand off the input device to input data.

[Problem to be solved by the invention]

The conventional CAD input devices mentioned above require the use of both hands, and when keyboard input is required, one must take one's hand off the input device, so CAD input devices such as a stylus pen are used. It becomes a hassle to hold and release the button, and input time is wasted.

Also, frequently used commands such as BREAK and CANCEL must be selected from the screen menu each time, so you have to move your hand back and forth from one end of the tablet to the other, making input more efficient. There is a drawback that there is no

[Means to solve the problem]

A CAD input device of the present invention is a CAD input device that receives and captures a screen menu with a stylus pen and separately specifies a command for the screen menu, and is configured to include at least one command switch on a side wall of the stylus pen. .

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing the configuration of an embodiment of the present invention.

The external structure of the stylus pen has a stop (STOP) and cancel (CANCEL) delimiter (B
REAK) buttons are added.

That is, switches IA to 5A corresponding to push buttons 1 to 5 are provided inside the shaft part, and terminals on one side of switches IA to 5A are led to connectors 7 at the ends of cables 8 each made of separate electric wires, and connected to connector bins. Form IB-5B.

On the other hand, a data receiving sensor 6A is arranged at the tip of the pointed light receiving section 6 at the tip of the shaft, and one signal line from the sensor 6A is also guided to a connector 7 at the tip of the cable 8 to form a connector bin 6B. . Further, the terminals at the other ends of the switches IA to 5A and the signal line at the other end of the sensor 6A all become one electric wire (common line) and are led to the connector 7 at the tip of the cable 8 to form a connector bin C.

In such a configuration, when using the stylus pen, by providing push buttons 1 to 5 in positions that are easy to press with the finger holding the stylus pen, when inputting commands indicated by the push buttons, it is possible to input commands directly from the stylus pen. No keyboard or mouse operations are required.

In this embodiment, the number of commands is five, but the number of push button switches and cable cores is equal to five.

By changing the number of connector bins, you can freely increase or decrease the number of commands. Also, although the return path of the switch and the return path of the light receiving sensor are all common (-), depending on the configuration of the control circuits of the switch and the light receiving sensor, it is possible to lead part or all of the return path to the connector with an independent wire. be.

〔Effect of the invention〕

As explained above, by using the present invention as a CAD input device, it is possible to select the normal commands of CA and D with one hand, and by arranging frequently used commands as buttons, the movement of the hand is reduced. Separate without doing (B
You can execute commands such as REAK) and cancel (CANCEL). Therefore, there is an effect that CAD input can be performed faster than in the past.
