Abstract:
1. A mobile communication device having a camera assembly, the camera assembly comprising: a camera; and a first portion adapted to rotate said camera, said first portion comprising a housing, a gear motor mounted in said housing for generating a rotational force, and a means for decelerating said rotational force for the purpose of rotating said camera, wherein said means for decelerating includes: a drive gear provided at a camera motor axle and adapted to decelerate said rotational force generated from said gear motor; a deceleration gear operatively coupled to said drive gear and deceleration-rotated with a certain ratio; a deceleration rotational axle for transmitting said decelerated rotational force; and a transmission gear operatively coupled between said drive gear and said deceleration gear, wherein a frictional plate is positioned between the camera and the deceleration rotational axle, the frictional plate transmitting driving force to the camera when the deceleration rotational axle is driven by the gear motor and stopping without rotation against a manual rotation of the camera when the gear motor is in a power-off state.
