An active-type stylus pen for manipulating a capacitive type touch screen, comprises a main housing of a sleeve shape, a printed circuit board, a front-end means, and an ON/OFF switch device, in which, a pen-tip receives electric signals from the printed circuit board and provides the electric signals to the touch screen when touching the touch screen. The ON/OFF switch device is disposed in an end portion of the active-type stylus pen and connected to the main housing. A switch mechanism is accommodated within an axial inner space of the ON/OFF switch device for selectively allowing the active-type stylus pen to be electrically-on or electrically-off. |

1. An active-type stylus pen for manipulating a capacitive type touch screen, comprising:
a main housing of a sleeve shape, wherein a first accommodation space is provided within the main housing for accommodating a battery; a printed circuit board for providing an electric signal; a front-end means comprising a housing connected to the main housing, wherein a second accommodation space is provided within the housing along an axial direction for accommodating at least a pen-tip, the front-end means has an opening at a first end to allow the pen-tip to be exposed from the housing, the pen-tip receives the electric signal at a second end, and the pen-tip provides the electric signal when touching the touch screen; and an ON/OFF switch device being disposed in an end portion of the active-type stylus pen and connected to the main housing, a switch mechanism is accommodated within an axial inner space of the ON/OFF switch device for selectively allowing the active-type stylus pen to be electrically-on or electrically-off, the switch mechanism comprises a back/forth moving means comprising a stator and a screw capable of moving forward or backward, an inclined groove being formed on the stator, and a pillar being disposed on the screw, and when the pillar is selectively located at a highest position of the inclined groove, the back/forth moving means is at a first dead point. |
