Abstract
Abstract If it is discriminated that an input coordinate is on a line of an already-prepared drawing, a cursor is displayed at an input coordinate position. Thereafter, the display position of the cursor is fixed until it is discriminated that the input coordinate is out of a predetermined area, which is based on the cursor position on the line, or on the line of the drawing in the predetermined area.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A drawing preparing system in a data processing apparatus, which has an integral display/input device (10) in which a display device and a coordinate inputting device are incorporated, prepares a drawing defined by a coordinate of a characteristic point designated by a cursor, and displays the drawing on said display device, characterized by comprising: first discriminating means (14, 15, 16) for discriminating whether or not a first coordinate input from said coordinate input device is on a line of an already-prepared drawing; second discriminating means (14, 15, 16) for discriminating whether or not a second coordinate input after discriminating that said first coordinate is on the line of the drawing is out of a predetermined area including said first coordinate; third discriminating means (14, 15, 16) for discriminating whether or not said second coordinate input after discriminating that said first coordinate is on the line of the drawing is in the predetermined area including said first coordinate; and cursor display position determining means (14, 15, 16, 17) for determining a cursor display position in accordance with the results of discrimination by said second and third discriminating means.
Claim 2
Dependent Claim
95 words
The system according to claim 1, characterized in that said cursor display position determining means unchanges the display position of the cursor after determining the cursor display position on said first coordinate whose position is discriminated by said first discriminating means that said first coordinate is on the line of the drawing excepting that it is discriminated by said second discriminating means that said cursor is out of said predetermined area and that it is discriminated by said third discriminating means that said cursor is on the line of the drawing in said predetermined area.
Claim 3
Dependent Claim
74 words
The system according to claim 1, characterized in that said first discriminating means comprises area discriminating means for discriminating whether or not said first coordinate is included in an area including the already-prepared drawing, and coordinate position discriminating means for discriminating whether or not said first coordinate is on the line based on the types of drawings in the corresponding area when it is discriminated that said first coordinate is included in said area.
Claim 4
Dependent Claim
31 words
The system according to claim 1, characterized in that said predetermined area including said first coordinate is determined by a distance set in advance on a basis of said first coordinate.
Claim 5
Independent Claim
153 words
A method for preparing a drawing defined by a coordinate of a characteristic point designated by a cursor, characterized by comprising the steps of: a first discriminating step (S6, S7, S8, S9, S10) for discriminating whether or not an input first coordinate is on a line of an already-prepared drawing; a second discriminating step (S17, S18) for discriminating whether or not a second coordinate input after discriminating that said first coordinate is on the line of the drawing is out of a predetermined area including said first coordinate; a third discriminating step (S9, S10) for discriminating whether or not said second coordinate input after discriminating that said first coordinate is on the line of the drawing is in the predetermined area including said first coordinate; and a cursor display position determining step (S12) for determining a cursor display position in accordance with the results of discrimination by said second and third discriminating means.
Claim 6
Dependent Claim
95 words
The method according to claim 5, characterized in that said cursor display position determining step unchanges the display position of the cursor after determining the cursor display position on said first coordinate whose position is discriminated by said first discriminating step that said first coordinate is on the line of the drawing, excepting that it is discriminated by said second discriminating step that said cursor is out of said predetermined area and that it is discriminated by said third discriminating step that said cursor is on the line of the drawing in said predetermined area.
Claim 7
Dependent Claim
79 words
The method to claim 5, characterized in that said first discriminating step comprises an area discriminating step (S6, S7, S8) for discriminating whether or not said first coordinate is included in an area including the already-prepared drawing, and coordinate position discriminating step (S9, S10) for discriminating whether or not said first coordinate is on the line based on the types of drawings in the corresponding area when it is discriminated that said first coordinate is included in said area.
Claim 8
Dependent Claim
31 words
The method according to claim 5, characterized in that said predetermined area including said first coordinate is determined by a distance set in advance on a basis of said first coordinate.
