Abstract:
1. A direction indicating device, for generating a two-dimensional (2D) direction indicating signal in an electronic device, comprising: a base board; a first rectangular conductive plane, formed on the base board, comprising a first sliding slot; a second rectangular conductive plane, formed on the base board, overlapping the first rectangular conductive plane, comprising a second sliding slot; a positioning axle, perpendicular to the base board, passing through a space corresponding to overlap portions of the first sliding slot and the second sliding slot, for moving the first rectangular conductive plane along a first direction and moving the second rectangular conductive plane along a second direction when an external force is received; and a control signal generating module, for outputting the 2D direction indicating signal according to electric information from an end of the first rectangular conductive plane to an end the second rectangular conductive plane and electric information from the end of the second rectangular conductive plane to another end the first rectangular conductive plane; wherein the first rectangular conductive place and the second rectangular conductive plane are electrically connected; wherein the control signal generating module comprises:
