CONSTITUTION:The cursor display command data is instructed and inputted to a cursor switch circuit 7 by a display cursor command key 3. Thus, the desired several types of cursors to be displayed can be instructed with proper switching. In addition, the instructions for the unit graduation of the cursor can be inputted as the numerical data with use of a position data input key 4. Then the cursor can be directly shifted to each desired position with input of the absolute position of the cursor. Meanwhile, a data arithmetic control circuit 8 calculates the numerical data inputted by the key 4 based on the arith metic command data received through the key 3 and outputs the arithmetic result to a display controller. Thus, the cursors can be displayed in accordance with the desire of each user.</p> |
