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.
