PURPOSE:To improve the operability of a cursor position controller, by combining the shift of a cursor and that of a screen. CONSTITUTION:A cursor shifting device 4 shifts a cursor on a CRT6 in the direction detected by a horizontal position detector 2 at a speed proportional to the position of the detector 2. A CRT screen shifting device 5 shifts a screen on the CRT6 in the direction detected by a vertical position detector 3 and at a speed proportional to the position of the detector 3. The CRT6 displays both the CRT screen and the cursor which are decided by the devices 5 and 4, respectively. |
