Apparatus for driving electronic device and driving method thereof

An apparatus for driving an electronic device comprising:

• a housing having a seat recess;
• an input signal transfer main body that is fitted into the seat recess in whole or in part, and controls movement of a pointer displayed on a screen display unit;
• a direction detecting means that is located on the top of the input signal transfer main body, and generates a movement direction signal of the pointer;
• and
• a speed detecting means that is located at the bottom of the input signal transfer main body, and generates an additional movement signal or a movement speed change signal of the pointer in response to pressing pressure of the input signal transfer main body when the pressing pressure is applied,
• wherein the movement of the pointer displayed on the screen display unit is controlled using at least one of the movement direction signal of the pointer which is generated by the direction detecting means, the additional movement signal of the pointer which is generated by the speed detecting means, and the movement speed change signal of the pointer which is generated by the speed detecting means.
