Summary:PURPOSE:To easily incorporate, in a keyboard, a pressure sensing portion of a controller capable of moving a cursor under the control upon depression of the front, rear, right and left edges of a character input key of the keyboard so as to enhance productivity. CONSTITUTION:In a cursor controller for a cathode-ray tube (CRT) where a pressure sensing portion 15 is disposed in a predetermined character input key 11 of a keyboard 10 and upon depression of the front, rear, right and left edges of the input key 11, the pressure sensing portion 15 detects the depressing direction to move a cursor of the CRT under the control, the pressure sensing portion 15 is formed independently of the keyboard 10, and it is fixed in the keyboard 10. A troublesome indivisual incorporating work of small sized parts of the pressure sensing portion 15 in the keyboard 10 is eliminated.
