Claims

[Claims for Utility Model Registration] In a display capable of moving a cursor on a display screen using a mouse, an origin coordinate storage means for storing origin coordinate data on the display screen, and a cursor position at the current point in time. current coordinate storage means for storing coordinate data; first distance calculation means for calculating the distance between each coordinate using the origin coordinate storage means, current coordinate storage means, and each coordinate data; cursor speed setting means for setting a cursor speed coefficient that increases sequentially in accordance with distance data; and cursor current information based on data obtained by multiplying the input movement data from the mouse by the cursor speed coefficient and coordinate data of the origin coordinate storage means. A current coordinate rewriting means for obtaining coordinate data and updating the coordinate data in the current coordinate storage means to newly obtained coordinate data; a previous coordinate storage means for storing coordinate data of a cursor from a certain time ago; a timer; A previous coordinate rewriting means rewrites coordinate data in the previous coordinate storage means to coordinate data in the current coordinate storage means each time the timer measures a certain period of time; a second distance calculation means that calculates the distance between each coordinate using each coordinate data of the means; If the distance calculated by the second distance calculation means is smaller than the minimum cursor movement distance corresponding to the annular area including the distance calculated by the distance calculation means, the coordinate data of the origin coordinate storage means is converted to the coordinate data of the current coordinate storage means. What is claimed is: 1. A mouse cursor control device for a display, comprising: origin coordinate rewriting means for rewriting origin coordinates to a current coordinate storage means;
