<p>PROBLEM TO BE SOLVED: To make accurately stoppable a mouse cursor at a display object in a short time and to make enhancible the working efficiency by automatically and instantaneously moving the mouse cursor to an after-image position on the display object when moving the mouse cursor passing through on the display object backward. SOLUTION: A 1st mouse coordinate register 9 reads a mouse coordinate signal from a mouse coordinate register 4, stores it for a fixed period and outputs it as a 1st mouse coordinate signal. A 2nd mouse coordinate register 10 reads the 1st mouse coordinate signal, stores it for a fixed period and outputs it as a 2nd mouse coordinate signal. A backward movement detecting part 9 compares and processes a mouse coordinate signal from the register 4, the 1st mouse coordinate signal from the register 9 and the 2nd mouse coordinate signal from the register 10, detect the backward movement of a mouse cursor and also transmits a backward movement detection signal to the register 4. When the register 4 receives the signal rewrites an output signal into an after image coordinate signal.</p> |
