<p>PURPOSE:To easily find out a cursor when the eyes are separated from a screen and the screen is observed again after that by changing the display mode of the cursor transiently when the no-operating time of an instruction means exceeds a prescribed time in the case of detecting the operation of the instruction means. CONSTITUTION:A cursor display switching device 7 starts an operation when mouse operation detection, i.e., a pulse PS from an operation detection circuit 6 is supplied. Difference D between a variable now-Time and a variable preTime is taken, and it is Judged whether or not it exceeds a prescribed value maxTime. Meanwhile, when the prescribed time elapses until a mouse 1 is slided after it is slided last time, the cursor display switching device 7 starts up a cursor flash device 15. An ordinary cursor form and an inversion cursor form are supplied by switching to a cursor managing device 2 for several seconds. Thereby, since the cursor flashes transiently when a state where the cursor is embedded in screen data is set, etc., the cursor is easily found out.</p> |
