<p>PURPOSE:To easily detect a cursor by emphasizing the cursor while it stops. CONSTITUTION:If the content of a counter 13 is bigger than a previously regulated value, the signal of 'yes' is transmitted to an emphasis means 14 through a signal line 105. If a signal through the signal line 105 is 'no', namely, while the cursor shifts or while it stops within the range of a prescribed period, the means 14 transmits the coordinate output of a pointing means 11 transmitted through a signal line 104 as it is to a coordinate calculation means 15 through a signal line 106, whereby the cursor is displayed in a position concerned. If the signal through the signal line 105 is 'yes', namely, if the cursor is in a stop state for more than prescribed period, the cursor emphasis means 14 generates a signal which periodically fluctuates with '0' as a signal in the direction of 'y', and '0' as the signal in the direction of 'x' in a center, for example, and it transmits it to the mentioned coordinate calculation means 15 through a signal line 106.</p> |
