Abstract

PURPOSE:To simplify the complicated operation required for input of a graphic symbol and to shorten the time required for production of a circuit diagram by performing simultaneously and selectively both the insertion and the copying of the graphic symbol. CONSTITUTION:An input device for circuit diagram consists of a keyboard 1, a mouse 2, a processor 3, a storage 4, and a CRT 5. The processor 3 contains a microcomputer and reads the designated one of various graphic symbols out of the storage 4 to input the symbol to the circuit diagram shown on a display screen of the CRT 5. In this case, both a graphic symbol insertion means A and a graphic symbol copy means B can be selected at one time with designation of an insertion/copy selection means C. Thus it is not required to perform the designation for each inserting/copying job of the graphic symbol. Then the input operation is simplified for the graphic symbol and the time required for production of the circuit diagram is shortened.

Generally, circuit diagram input devices are known that create a circuit diagram of an electric circuit or the like on the display screen of a single display device by inputting graphic symbols and signal lines of electrical components using a keyboard, mouse, or the like.

Conventionally, this circuit diagram input device has a function of specifying a desired graphic symbol from a menu area where pre-registered graphic symbols are displayed and inserting it into the circuit diagram, and a function of inserting a graphic symbol that has already been input into the circuit diagram into the circuit diagram. Some had the ability to copy the diagram to other positions.

[Problem to be solved by the invention]

However, in the circuit diagram input device as described above, when inserting or copying a graphic symbol.

It is necessary to specify the insert or copy function in advance, and the function specification operation must be performed each time each operation is performed, which is troublesome for the operator.

The present invention has been made in view of the above points, and an object of the present invention is to simplify the operation when inputting graphic symbols and shorten the time required to create a circuit diagram.

[Means to solve the problem]

In order to achieve the above object, the present invention, as shown in the functional block diagram of FIG. A circuit comprising a graphic symbol inserting means A for placing a graphic symbol at a designated position in an area, and a graphic symbol copying means B for specifying a graphic symbol displayed in a work area and copying and placing it at an arbitrary designated position within the work area. This figure input device is provided with insertion/copy selection means C for simultaneously selecting the functions of the graphic symbol insertion means A and the graphic symbol copying means B.

[For production]

In the circuit diagram input device according to the present invention, if the insertion/copy selection means C is specified when inputting a graphic symbol, the graphic symbol insertion means A and the graphic symbol copying means B can be selected at the same time, so that one graphic symbol can be inserted. Also, there is no need to specify it for each copying operation.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to FIG. 2 and subsequent drawings.

FIG. 2 is a block diagram showing the configuration of a circuit diagram input device that is an embodiment of the present invention.

This circuit diagram input device includes a keyboard 1. Mouse 2, processing device 3. Storage device 4. The processing device 3 is composed of a CRT 5 and is equipped with a microcomputer inside.

A keyboard 1 and a mouse 2 are used to simultaneously select the input, insertion, and copying of graphic symbols and signal lines, as well as input instructions for various other functions related to circuit diagram creation.

Then, the processing device 3 reads out the designated graphic symbol from the storage device 4 in which various graphic symbols are stored, and inputs it into the circuit diagram displayed on the display screen of the CRT 5, which is a display device.

At this time, one graphic symbol insertion means A, two graphic symbol copy means B, an insertion/copy selection means C, and various other functions related to circuit diagram creation are realized.

Next, the input of graphic symbols using the function of simultaneously selecting insertion and copying will be explained with reference to FIGS. 3 and 4.

FIG. 3 is a diagram showing the operating procedure of the operator at that time,
The steps of instructing a command, instructing a graphic symbol to be input, and arranging the graphic symbol are performed in this order.

Figure 4 shows CRT5 display screen 6 when inputting one figure symbol.
FIG.

This display screen 6 includes a work area 7 which is an area where a circuit diagram is created by inputting graphical symbols and signal lines, and a command area 8 where commands for instructing various functions related to creating a circuit diagram are displayed. There is also a menu area 9 in which graphic symbols registered in advance are displayed.

The operator selects the mouse cursor 10 that is displayed on the display screen.
Move to match the command or graphic symbol.

First, the operator moves the mouse cursor 10 to the command area 8
When the mouse button is pressed in accordance with "insert/copy" 11, the insert/copy selection function is instructed.6 Next, the mouse cursor 10 is moved to select and specify the graphic symbol to be input.

At that time, to select from the menu area 9, place the mouse cursor 10 within one of the frames in the menu area 9 in which various graphic symbols such as the graphic symbol 12 are displayed, and press the mouse button. In addition, to select from among the graphic symbols already stored in the work area 7, the mouse cursor 10 is placed within the area occupied by the graphic symbol, such as the graphic symbol 13, and the mouse button is pressed.

To change to another graphic symbol, place the mouse cursor 10 on the graphic symbol and press the mouse button, and the symbol will be changed automatically.

Then, the designated graphic symbol is displayed in a dragging manner, moving with the mouse cursor 10, so when the mouse cursor 10 is moved to a desired position in the work area 7 and the mouse button is pressed.

A graphical symbol 12 or 13 is input into the circuit diagram.

Furthermore, by pointing the graphic symbol in the work area 7, moving the mouse cursor 10 to a desired display field in the menu area 9, and pressing the mouse button, the graphic symbol can be registered in the menu area 9.

Note that when placing one graphic symbol on a circuit diagram, if the mouse button is pressed while the mouse cursor 10 is in an area occupied by a low-input graphic symbol, the input graphic symbol will be changed.

Therefore, as shown in FIG. 5, the area where a low-input graphic symbol is indicated by the mouse cursor 10 is changed from an area 14 occupied by the graphic symbol indicated by a broken line to an area 15 occupying the center of the graphic symbol as indicated by a diagonal line. It is best to narrow it down to

Next, according to the flowchart of FIG.
The processing will be explained.

First, when the mouse button is pressed by the operator in step 1, it is determined in step 2 whether there is a graphic symbol under the mouse cursor 10 (indicating a graphic symbol).

If there is a graphic symbol, the process proceeds to step 3 where it is determined whether the graphic symbol is the graphic symbol of the work area 7 or the menu area 9.

Then, if it is a graphic symbol in menu area 9, the process advances to step 5, where that graphic symbol is determined as the graphic symbol to be input, and the process returns to step 1.

If it is a graphic symbol in the work area 7, proceed to step 4 and determine whether or not the mouse cursor 10 has pointed to the area occupying the center of the graphic symbol (the area shown with diagonal lines in FIG. 5). If so, in step 5 the graphic symbol is determined as the graphic symbol to be input and the process returns to step 1; if not, then
In step 6, error processing is performed and the process returns to step 1.

Next, when the mouse button is pressed again by the operator, the process advances from step 1 to step 2, and the mouse cursor 1
If there is no graphic symbol under 0, proceed to step 7.

Then, it is determined whether the graphic symbol to be manually input has been determined, and if it has been determined, the process proceeds to step 8, where it is determined whether the mouse cursor 10 is located in the work area 7 or the menu area 9.

Then, if it is the menu area 9, the graphic symbol to be input in step 9 is newly registered in the menu area 9, and if the work area is 7, the graphic symbol to be input is placed at the position indicated by the mouse cursor 10 in step 1o. Return to

Also, when the mouse button is pressed by the operator,
If the mouse cursor 10 does not point to a graphic symbol and the graphic symbol to be input has not been determined, the process directly returns to step 1.
