Summary:PURPOSE:To make thin a keyboard provided with 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 and reduce a cost. 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, a pressure sensing element of the pressure sensing portion 15 detects the depressing direction to move a cursor of the CRT under the control, there is provided a special frame 23 for the pressure sensing portion 15. The special frame 23 presses the pressure sensing element by, e.g. tightly fastening with a screw, to thus apply a reference pressure.
