Abstract

PURPOSE:To shorten the designing time by omitting the troublesome switching operations of various screens for input of the data when a circuit diagram, etc., are inputted for production in a CAD system. CONSTITUTION:If it is required to fetch the data on the circuit component elements like a NOR gate, etc., when a circuit diagram, etc., are designed by the CAD, a mouse 1 containing a bar code reading function is moved on a data sheet 2 where the data to be inputted are written in a bar code. Thus the necessary data can be fetched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input method for a CAD system, and more particularly to a data input method for a CAD system using auxiliary input means called a mouse.

[0002]

2. Description of the Related Art The conventional input method of this type of CAD system is to input while switching between a design screen and a data selection screen with a mouse as shown in FIG. For example, when designing a circuit, a mouse 7 opens a required window or switches screens. When the data selection window is opened, the data selection window screen 6b is displayed on the display 6.

Here, the designer selects the necessary data from the display on the screen with the mouse 7, then switches the screen with the mouse 7 and returns to the circuit design surface. After making necessary inputs in that state, the screen returns to the data selection screen shown in FIG. 4 again to select the necessary data. Hereinafter, the same operation is repeated to complete the circuit.

[0004]

In the above-mentioned conventional input method, since it is necessary to switch the screens many times to select and input the constituent elements on the design screen, it takes time to input the data. It was complicated and the work was complicated.

[0005]

According to a data input method of a CAD system of the present invention, a mouse which is an input assisting device for inputting necessary data from a dedicated data sheet in which a plurality of data to be input is bar-coded and recorded. Select and read by.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration diagram of a CAD system using an input method according to an embodiment of the present invention. Further, FIG. 2 is a rear view of a mouse having a barcode reading function used in this embodiment, and FIG. 3 shows an example of a dedicated data sheet used in this embodiment.

In the data sheet 2, as shown in FIG.
A plurality of sets of bar coded information 3, a symbol 4 of data to be input and a code number 5 of data are described. Further, as shown in FIG. 2, a barcode reading section 1a is provided on the back side of the mouse 1.

The circuit designer uses the circuit design system to perform the required processing on the circuit design screen 6a shown in FIG. When it becomes necessary to read the constituent elements during the design, the bar code reading unit 1a of the mouse 1 is passed over the bar code corresponding to the symbol of the necessary data on the dedicated data sheet 2.

This allows the necessary components (eg N
The data of the OR gate) is taken into the circuit design system. Hereinafter, the required circuit design is performed by repeating the same operation.

As described above, according to the present invention, the trouble of opening another window or switching to another screen is eliminated, and the loss time for that is eliminated, so that an efficient design is possible.

The preferred embodiment has been described above.
The present invention is not limited to this embodiment, and can of course be applied to CAD other than circuit design, and various modifications can be made to the embodiment, for example, by replacing the data sheet with a tablet format. Is.

[0012]

As described above, according to the present invention, the CAD is directly performed by reading the bar coded data by using the input assisting device having the bar code reading function.
Since information can be input to the system, the present invention can shorten the input time in CAD and simplify the input method.

Also, by having a dedicated data sheet, the memory load in the CAD system can be reduced,
Furthermore, since it is not necessary to prepare a component selection window, the system can be downsized.
