DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a diagram showing the configuration thereof. In FIG. 1, reference numeral 10 is a control unit such as a CPU for controlling the whole. Reference numerals 12 and 14 are a keyboard and a mouse as input devices, and 16 is a display device as an output device.

Reference numeral 18 is an external character editing unit that uses the external character creating memory 20 as a work memory to execute an external character creating function, and 22 is an external character registration memory that stores the created external character pattern.

Reference numeral 24 is a storage unit as a work memory used when the control unit 10 executes a display process which will be described later. The storage unit 24 includes a mouse movable range storage unit 26, a function-based click effective range storage unit 28, a current mouse coordinate storage unit 30, and a previous mouse coordinate storage unit 32.

The mouse movable range storage unit 26 stores the mouse cursor 3 on the display screen 34 as shown in FIG.
This is an area for registering a range in which 6 can move (hereinafter referred to as mouse moving range 38). Here, as coordinate information for specifying the mouse movement range 38, X left end coordinates (Xl), X right end coordinates (Xr), Y upper end coordinates (Yt),
And Y bottom coordinate (Yb) are stored.

The effective click range 28 for each function is the mouse 1
Range in which the dot pattern erasing function is enabled when the right button of 4 is clicked (hereinafter referred to as external character creation effective range 40
Area) is registered. Here, X left end coordinates (XDl), X right end coordinates (XDr), Y upper end coordinates (YDt), and Y lower end coordinates (YDb) are stored as coordinate information for specifying the external character creation effective range 40.

The current mouse coordinate storage unit 30 is an area for storing the current coordinates of the mouse cursor 36. Here, the X coordinate (Xc) and the Y coordinate (Yc) are stored as the coordinate information of the mouse cursor 36.

The previous mouse coordinate storage unit 32 is an area for holding the position where the mouse cursor 36 was before moving to the current position. Here, X coordinate (Xp) and Y coordinate (Y
p) is stored.

Next, in such a configuration, the mouse 1
The operation process when 4 is right-clicked will be described with reference to the flowchart of FIG.

First, the current cursor coordinates are acquired, and the current cursor coordinates are stored in the X coordinate (Xc) and Y of the mouse coordinate storage unit 30 this time.
It is stored in the coordinates (Yc) (step S11). And
It is checked whether or not the mouse has been moved (step S
12). This is because the X coordinate stored in the X coordinate (Xc) of the mouse coordinate storage unit 30 this time is the same as the X coordinate stored in the X coordinate (Xp) of the previous mouse coordinate storage unit 32, and this time. Mouse coordinate storage unit 30 Y coordinate (Yc)
And the Y coordinate stored in the mouse coordinate storage unit 32 of the previous time.
If the Y coordinate stored in the coordinate (Yp) is the same (that is, if Xc = Xp and Yc = Yp), it is determined that the mouse has not moved, and otherwise it is determined that the mouse has moved. To do.

When the mouse is moved, the X coordinate (Xc) and the Y coordinate (Yc) of the mouse coordinate storage unit 30 of this time.
It is checked whether or not the coordinates stored in is within the mouse movement range 38 (step S13). This is because the X coordinate stored in the X coordinate (Xc) of the mouse coordinate storage unit 30 this time is the value of the X coordinate stored in the X left end coordinate (Xl) of the mouse movable range storage unit 26 and the X right end coordinate ( Xr)
The Y coordinate stored in the mouse coordinate storage unit 30 and stored in the Y coordinate (Yc) of the mouse coordinate storage unit 30 is stored in the Y upper end coordinate (Yt) of the mouse movable range storage unit 26. Value of Y coordinate and Y stored in Y bottom coordinate (Yb)
If it is between the coordinate value (that is, if Xl <Xc <Xr and Yb <Yc <Yt), it is determined to be within the mouse movement range 38, otherwise it is determined to be outside the mouse movement range 38. .

If it is outside the mouse movement range 38, the process immediately returns to step S11. If it is within the mouse movement range 38, cursor coordinate movement processing is performed (step S14).
Returning to step S11, the above operation is repeated. In this cursor coordinate movement process, the value of the X coordinate stored in the X coordinate (Xc) of the mouse coordinate storage unit 30 this time is stored in the X coordinate (Xp) of the previous mouse coordinate storage unit 32. The Y coordinate (Y
This is a process of storing the value of the Y coordinate stored in c) in the previous Y coordinate (Yp) of the mouse coordinate storage unit 32.

On the other hand, if it is determined in step S12 that the mouse has moved, then the mouse 1
It is determined whether or not any one of the buttons 4 is clicked (step S15). If the click operation has not been performed, the process returns to step S11 and the above operation is repeated.

When a click operation is performed,
It is determined whether it is a right button click or a left button click operation (step S16).

If it is the left button click operation, it is checked whether the current position of the mouse cursor 36 is within the external character creation effective range (external character creation area) 40 (step S1).
7).

This external character creation effective area (external character creation area)
The check operation is performed as shown in FIG. That is, the X coordinate (X
The value of the X coordinate stored in c) is greater than or equal to the value of the X coordinate stored in the X left edge coordinate (XDl) of the function-specific click effective range storage unit 28, and the X right edge coordinate (XDr) is stored. It is less than or equal to the coordinate value (that is, XDl ≦ Xc ≦ XDr) (step S31), and the value of the Y coordinate stored in the Y coordinate (Yc) of the mouse coordinate storage unit 30 this time is the click effective range storage unit by function. 28 is less than or equal to the value of the Y coordinate stored in the Y upper end coordinate (YDt) and the Y lower end coordinate (Y
Db) is greater than or equal to the Y coordinate value stored (that is, YDt ≧ Y
If c ≧ YDb), it is determined to be within the external character creation effective range 40, and otherwise it is determined to be outside the external character creation effective range 40.

When it is determined that the character is within the external character creation effective range 40, the dot of the external character pattern corresponding to the coordinate position on the display screen 34 is turned on and the external character editing unit 18 sets the corresponding dot for external character creation. After writing in the memory 20 (step S18), the process returns to step S11 and the above operation is repeated. Also, the external character creation effective range 40
If it is determined to be outside, nothing is done (step S19), the process returns to step S11, and the above operation is repeated.

On the other hand, if it is determined in step S16 that the right button is clicked, it is checked whether the current position of the mouse cursor 36 is within the external character creation effective range 40 as described above (step S2).
0).

When it is determined that the character is within the external character creation effective range 40, the dot of the external character pattern corresponding to the coordinate position on the display screen 34 is turned off, and the external character editing unit 18 sets the corresponding dot for external character creation. After erasing from the memory 20 (step S21), the process returns to step S11 and the above operation is repeated.

If it is determined that the character is outside the valid range 40 for creating the external character, the external character edit menu window is displayed on the display screen 34 (step S22), and a desired menu selection is made (step S23). Processing proceeds to the processing of the selected menu. For example, if the registered process of the created external character pattern is selected in the external character editing menu window, the pattern stored in the external character creation memory 20 by the external character editing unit 18 is stored in the external character registration memory 2.
Store in 2.

As described above, by setting the clickable effective range for each function in addition to the movable range of the mouse, the function in the mouse operation is controlled, so the coordinates when the mouse button is clicked. It becomes possible to select an effective function by using, and it is possible to prevent multiple functions from operating.

In the above embodiment, the external character dot is turned on by clicking the left button of the mouse and turned off (turned off) by right clicking.
However, the right and left may be reversed.

Further, the present invention is not limited to the external character creation as in the above-mentioned embodiment, and it is needless to say that the present invention can be applied to other functions such as graphic drawing.
