<p>PURPOSE:To realize a cursor position moving control system superior in operability where a cursor is movable in an optional direction by one touch operation, by placing a movable object provided with an optical detector on a panel surface and, moving the movable object in the direction where the cursor is moved. CONSTITUTION:A movable object 2 provided with the optical detector which detects cell information of a panel surface 1 is placed on the panel surface 1 where a pattern is formed, and optical information corresponding to each cell of the pattern on the panel surface 1 is read by this movable object 2. Read optical information is sent to a CPU 4 through an amplifying circuit 3. This CPU 4 has a memory 4A where information of the panel surface 1 where the pattern is formed is stored. The CPU 4 discriminates the sequence of read information, which is changed in accordance with movement of the movable object 2, by information from the memory 4A to detect the movement direction. A cursor moving control signal 5 is sent to a CRT control circuit 6 in accordance with this movement direction to move the cursor displayed on a CRT 7.</p> |
