The position designation element acquisition means 2 receives the position information 101 for displaying the cursor, inspects the display element information 6 to check whether or not the character displayed at the position of the position information 101 exists. The position specifying element information 201 including the presence flag indicating whether or not a character exists and the display range of the character is output. The standard cursor acquisition means 3 receives the input of the position information 10, finds the range of the standard cursor including the position of the position information 101, and outputs the standard cursor range information 301 including the range of the standard cursor. The range designation element acquisition means 4 receives the standard cursor range information 301, searches the display element information 6 to check whether or not a character displayed is within the designated range of the standard cursor, and The range specifying element information 401 including the existence flag indicating whether or not the character exists and the existence range of the character is output. The cursor display means 5 receives the cursor display range information 102 indicating the range of the cursor to be displayed, and displays the cursor on the screen with a dotted line. The cursor shape determining means 1 uses position information 1
01 is output to acquire the position specification element information 201 from the position specification element acquisition unit 2 and the standard cursor range information 301 from the standard cursor acquisition unit 3, and the acquired standard cursor range information 301 to the range specification element acquisition unit 4 And the range designation element information 401 is acquired. On the other hand, when the presence flag of the acquired position designation element information 201 is “present”, the cursor display means 5 sets the display range of characters in the position designation element information 201 as the cursor display range information 102.
When the presence flag of the acquired position designation element 201 is “none” and the presence flag of the range designation element information 401 is “none”, the standard cursor acquisition means 3
The standard cursor range information 301 returned from is output to the cursor display means 5 as the cursor display range 102. Furthermore, when the presence flag of the acquired position designation element information 201 is “absent” and the presence flag of the range designation element information 401 is “present”, the range designation element information 401 from the range of the obtained standard cursor range information 301 The range excluding the range is output to the cursor display means 5 as the cursor display range information 102.

FIG. 2 is a diagram showing a specific example of the display in the embodiment of FIG. 1 and is intended for the case where the character "A" larger than the size of the line column by about 30% is displayed.

FIG. 2A shows the case where the cursor position designation is given within the range of the displayed character "A". When the cursor shape determination means 1 sends the position information 101 to the position designation element acquisition means 2, the position designation element acquisition means 2 sends the position information 10
The display element information 6 is searched based on 1 and the character "A" is detected, and the position designation element information 201 including the existence flag "Yes" and the character range is returned. Since the presence flag of the position designation element information 201 of the cursor shape determination means 1 is “present”, the range of the cursor to be displayed is determined by the position designation element information 201.
The character range of the position designation element information 201 is sent to the cursor display means 5 as the cursor display range information 102. The cursor display means 5 uses the range of the cursor display range information 102 as the size of the cursor, and
As shown in (b), a cursor with the range of the character "a" as a dotted line is displayed.

FIG. 2 (c) shows a case where the cursor position is specified outside the range of the displayed character "a" and within the range of the line columns included in this range. Cursor shape determination means 1
When the position information 101 is sent to the position designation element acquisition means 2,
The position designation element acquisition unit 2 searches the display element information 6 based on the position information 101, but cannot detect the character and returns the position designation element information 201 including the existence flag “none”. In this case, the cursor shape determination means 1 sends the position information 101 to the standard cursor acquisition means 3. Standard cursor acquisition means 3
Calculates the range of the standard cursor based on the position information 101 and returns the standard cursor range 301. Cursor shape determination means 1
Further searches the display element information 6 based on this standard cursor range 301, and returns the position designation element information 401 including the range of the existence flag “present” and the character “a”. The cursor shape determining means 1 determines the range of the cursor to be displayed from the standard cursor range information 301 to the range specifying element information based on the presence flag “absent” of the position specifying element information 201 and the presence flag “existing” of the range specifying element information 401. It is determined that the range is the range excluding the character range obtained in 401, and the range excluding the range of the character obtained in the range specification element information 401 from the standard cursor range information 301 is displayed on the cursor display means 5 as the cursor display range information. Send as 102. As shown in FIG. 2D, the cursor display means 5 displays the range of the cursor display range information 102 as the size of the cursor on the screen with a dotted line.

FIG. 2 (e) shows the case where the cursor position designation is given to the range of the line column adjacent to the range of the displayed character "a". When the cursor shape determination unit 1 sends the position information 101 to the position designation element acquisition unit 2, the position designation element acquisition unit 2 searches the display element information 6 based on the position information 101, but the character cannot be detected, and the presence exists. The position designation element information 201 including the flag “none” is returned. In this case, the cursor shape determination means 1 sends the position information 101 to the standard cursor acquisition means 3. The standard cursor acquisition unit 3 obtains the range of the standard cursor based on the position information 101, and returns the standard cursor range information 301. The cursor shape determination means 1 further sends the standard cursor range information 301 to the range designation element acquisition means 4. The range designation element acquisition means 4 searches the display element information 6 based on the standard cursor range information 301, but cannot detect a character and returns the range designation element information 401 including the existence flag “none”. The cursor shape determining means 1 also detects the presence flag of the position designation element information 201 and the range designation element information 401.
Since the presence flag of is also “none”, it is determined that the range of the cursor to be displayed is the standard cursor range information 301,
Standard cursor range information 301 and cursor display range information 1
02 to the cursor display means 5. As shown in FIG. 2F, the cursor display means 5 displays the range of the cursor display range information 102 as the size of the cursor on the screen with a dotted line.

In the above embodiment, the cursor is used to display the range with a dotted line, but the cursor may be displayed with a solid line regardless of the direction, and the range may be displayed with a mesh.

[0013]

As described above, according to the present invention, the range of the cursor to be displayed is determined by searching the position where the cursor is to be displayed and the range of the standard cursor including the position for a character. As a result, the cursor will not be displayed overlapping the displayed characters,
There is an effect that it is possible to accurately determine the next input position because the displayed characters are not difficult to determine and the movement is continuous.
