Patent ID: 7093950

Claim:
An illumination pen, comprising: a hollow pen holder having a receiving cavity, a lower light transmissible body, and a bottom opening communicating said receiving opening; a writer device, which comprises: a pen core, having a writing tip, disposed in said receiving cavity of said pen holder; an illumination device comprising a replaceable battery supported in said receiving cavity and at least an illuminator mounted in said receiving cavity; and an actuator, which comprises: a rotor rotatably provided on said pen holder; and a driving member, which comprises a conductive arm and a pushing arm, being driven by said rotor to move said pen core from a normal unemployed position to an operation position, wherein at said operation position, said rotor is rotated to drive said driving member to push said writing tip out of said pen holder at said bottom opening thereof, and at said unemployed position, said writing tip of said pen core is retracted in said receiving cavity; wherein said conductive arm functions as a switch and is arranged in such a manner that when said rotor is rotated at a clockwise direction from said unemployed position to move said driving member downwardly, said conductive arm is driven to electrically connect with said illuminator, such that said illuminator generates a light effect within said light transmissible body to an exterior thereof, so as to move said writing tip of said pen core out of said bottom opening of said pen holder; wherein when said rotor is rotated at a counter-clockwise direction from said unemployed position to move said driving member downwardly, said pushing arm is driven towards said illuminator to move said writing tip of said pen core out of said bottom opening of said pen holder.
