A camera driving device is provided. The camera driving device includes: a motor configured to generate a driving force; an input pulley attached to the motor; a gear assembly including a first gear coupled to the input pulley by a first timing belt, and a second gear formed coaxially with the first gear, the second gear configured to rotate together with the first gear; and an output pulley configured to rotate together with the second gear by a second timing belt, wherein a reduction is made according to a gear transmission ratio between the input pulley and the first gear, a reduction is made according to a gear transmission ratio between the second gear and the output pulley, and a rotation shaft of the output pulley is positioned between a rotation shaft of the input pulley and a rotation shaft of the first gear.

Camera driving device having a plurality of timing belts

A camera assembly includes a motor configured to generate a driving power; a motor shaft that extends from the motor, such as to define a first axis, and is configured to rotate by the driving power of the motor; a pulley configured to rotate on a second axis, that is spaced from the first axis, according to rotation of the motor shaft; a belt configured to couple the motor shaft and the pulley, and convert the rotation of the motor shaft to rotation of the pulley, and tension of the belt applies a force to the motor shaft in a direction towards the second axis; a camera module configured to be mounted on the pulley and rotate together with the pulley; and an elastic body configured to apply a biasing force to the motor shaft such as to bias the motor shaft in a direction away from the second axis.
