Game controller wiht mini control-wheel

Abstract

A portable or hand-held game controller comprises: a wheel rotation unit which is rotatable; a rotation detection unit for detecting a rotation angle and a rotation direction of the wheel rotation unit; and a circuit block for receiving data from the rotation detection unit and applying the data to a game.

1 . A portable or hand-held game controller, comprising:
 a wheel rotation unit which is rotatable;   a rotation detection unit for detecting a rotation angle and a rotation direction of the wheel rotation unit; and   a circuit block for receiving data from the rotation detection unit and applying the data to a game.   
   
   
       2 . The game controller of  claim 1 , further comprising a rotation load unit which is controlled by the circuit block to control a rotation load of the wheel rotation unit. 
   
   
       3 . The game controller of  claim 1 , wherein the wheel rotation unit includes:
 a wheel plate which is disposed or mounted on the main body of the game controller to be rotatable; and   at least more than one rotatable disk which are disposed on the upper part of the wheel plate.   
   
   
       4 . The game controller of  claim 1 , wherein the rotation detection unit includes:
 a detection plate which is connected to the wheel rotation unit in the same axis and has a plurality of holes formed on its circumference around the same axis; and   a sensor which transmits a signal that detects a rotation angle and a rotation direction of the detection plate to the circuit block.   
   
   
       5 . The game controller of  claim 4 , wherein the sensor includes a light emitting unit and a light receiving unit and has a structure that the plurality of holes formed on the detection plate pass between the light emitting unit and the light receiving unit. 
   
   
       6 . The game controller of  claim 2 , wherein the rotation load unit includes:
 a gear unit which is combined to the center axis of the wheel rotation unit; and   a motor which is combined to the gear unit, wherein the motor receives a control signal from the circuit block to inflict a rotation load on the wheel rotation unit through the gear unit.   
   
   
       7 . The game controller of  claim 2 , wherein the circuit block includes a rotation signal transmission unit and a load control unit; the rotation signal transmission unit receives a signal detected by the sensor, changes the signal into digital data and transmits the data to an input unit of the game controller; and the load control unit receives a data signal showing a game progress, namely, a speed or rotation of a moving object which races to generate a corresponding control signal and transmits the signal to the rotation load unit.
