ABSTRACT:
A multifunction electronic device with function comparable to joystick and tablet, comprising: an electromagnetic signal emitting unit, having an electromagnetic signal emitter arranged at the bottom thereof; a supporting frame, for fixing and supporting the electromagnetic signal emitting unit at a position over an electromagnetic signal receiving unit while allowing the same to be tilted and spun freely; the electromagnetic signal receiving unit, having a sensing circuit disposed therein for receiving the signals emitted from the electromagnetic signal emitter, capable of executing an operation with respect to the received signals for obtaining a coordinate of movement corresponding to the electromagnetic signal emitting unit while converting the coordinate of movement into electronic signal and transmitting the converted electronic signal to a computer; wherein, the cooperative operating of the electromagnetic signal emitting unit and the electromagnetic signal receiving unit is functioned as a digitizing tablet while the supporting frame is removed from the position over the electromagnetic signal receiving unit and the electromagnetic signal emitting unit is freed from the supporting frame.
