Abstract
A device for controlling a rotation of a lens in a digital camera includes a lens connected to and exposed out of the housing of a digital camera and a motor disposed within the housing of the digital camera. The lens is provided with a shaft which extends through the housing to have an end extending into the interior of the housing which is disposed with a follower gear. The motor has a drive spindle which is disposed with a driving gear. A set of reduction gears are disposed between and engageable with the follower gear on the shaft of the lens and the driving gear on the drive spindle of the motor. By means of the rotation of the motor, the lens is rotatable horizontally, while the digital camera remains stationary, to a desired direction in order to take a picture.
