| 摘要 |
A photographic device that includes a main body, a lens barrel and a barrel-positioning mechanism, which is operably coupled to the lens barrel and the main body. The barrel positioning mechanism is capable of moving the lens barrel between a retracted position, in which the lens barrel is within the main body, and an extended position, in which the lens barrel projects out of the main body. In some embodiments, the barrel positioning mechanism is a purely mechanical component that moves the lens barrel between the retracted position and the extended position in response to the lens barrel being pushed in a direction generally towards the main body. In other embodiments, the barrel positioning mechanism includes an electrical motor that helps extend and retract the lens barrel. In some embodiments, the extension/retraction of the lens barrel is triggered by software. |
