PURPOSE:To respectively individually and arbitrarily turn on/off a local system cursor and another system cursor by storing received coordinate information of the other system cursor and individually controlling whether the other system cursor and the local system cursor are to be superimposed and displayed or not by a cursor display control means. CONSTITUTION:Horizontal and vertical direction counters 11 and 13 count and hold the cursor positions of a local system according to a cursor switch 14. The outputs of the counters 11 and 13 are inputted through a local system cursor suppression processing part 17 to a local system cursor matching detection part 15. When matching with a display address from a display address generation part 4 is detected, the detection part 15 generates a local system cursor signal (q) and displayes the local system cursor in red through a switch 6. Similarly, the coordinate value of the other system cursor information is applied from a cursor suppression processing part 18 of the other system to a cursor matching detection part 16 of the other system and when matching is detected, the other system cursor is displayed in blue. Further, the cursors can be turned on/off with the local system and the other system cursor switches 20 and 21. |
