If step S11 is exited in the case of Yes, that is, if the input is an instruction to set the valid / invalid of the edit symbol, the valid / invalid of the edit symbol is displayed from the area shown on FIG. Is set, and the setting contents are stored in the main storage device 103 (step S12).

After the processing of step S12, it is determined whether or not the edit symbol is valid as a result of the setting (step S13). If the result of step S13 is Yes, that is, if the edit symbol is valid. Displays all edit symbols (step S14) and ends this processing.

If step S11 is answered No,
That is, if the input is not an instruction to enable / disable the edit symbol, it is determined whether or not the input is a movement input point movement using a pointing device or the like (step S15). If step S15 is exited with Yes,
That is, when the input point is a moving input, it is determined whether or not the input pointer input by the pointing device or the like is on or near the edit symbol (step S16).

If step S16 is exited in the case of Yes, that is, if the input pointer input is on or near the edit symbol, the edit symbol setting state stored in step S12 is referred to Step S17) for determining whether or not it is invalid. Then, when the step S17 is exited in the case of Yes, that is, when the edit symbol is invalid, the edit symbol near the input pointer is erased, and the symbol which is not near the pointer is displayed (step S18), and then the present process To finish.

On the other hand, if the result in step S15 is NO, that is, if it is not input movement of the input point, it is determined whether it is graphic editing input (step S1).
9) If the result is Yes, it is determined whether the edited symbol is valid (step S20). Further, when the result in step S20 is Yes, it is determined whether the input pointer input by the pointing device or the like is on the edit symbol (including its vicinity) (step S21),
If this is cleared by Ycs, the edit process corresponding to the specified edit symbol is performed (step S22), and this process ends. This editing processing includes enlarging / reducing the size of the figure in which the editing symbol was displayed.

Note that steps S19, S20,
If NO in step S21 and if NO in steps S13, S16, and S17, the process ends.

In this embodiment, since the edit symbol in the vicinity of the input point is erased when the edit symbol is set to be invalid, the figure to be operated is easy to see when the figure edit is input. Further, there is an advantage that it is easy to understand that the edit symbol is currently in the invalid mode by the operation of displaying or deleting the edit symbol by moving the input point.
