Abstract: An illumination pen includes a hollow pen holder having a receiving cavity and a lower light transmissible body, a writer device and an actuator. The writer device includes a pen core, an illumination device including a battery and an illuminator. The actuator includes a rotor rotatably provided on the pen holder, and a driving member including a conductive arm and a pushing arm. When the rotor is rotated at a clockwise direction, the conductive arm is driven to electrically connect with the illuminator so as to light it up, when the rotor is rotated at a counter-clockwise direction, the pushing arm is driven towards the illuminator to move the writing tip of the pen core out of the bottom opening of the pen holder.

Abstract: A multi-functional pen includes an elongated pen body having a lower body and an upper body, a writing unit, having a writing tip, disposed in the lower body of the pen body, and a pen actuator provided at the pen body to move the writing unit from a normal unemployed position to an operation position. The multi-function pen further includes an auxiliary functional arrangement including a memory unit received in the upper body of the pen body and a computer connector extended from the upper body of the pen body, wherein the computer connector is electrically connected to the memory unit for detachably connecting with a computer, such that the memory unit forms a removable storage for communicating with the computer to store a computer data thereof.
