Abstract

La présente invention concerne un mécanisme d’entraînement avec une pince linéaire pour entraîner en rotation une bague rotative d’un objectif sur un appareil photographique comprenant une base, une unité d’entraînement, une unité esclave et une unité de serrage, dans lequel la bague rotative peut être une bague de mise au point ou une bague de zoom. L’appareil photographique est maintenu sur la base, tandis que l’unité d’entraînement et l’unité esclave sont disposées de manière coulissante sur la base et situées sur les côtés opposés de l’objectif. L’unité d’entraînement comprend au moins une roue entraînée, et l’unité esclave comprend au moins une roue folle. L’unité de serrage est disposée sur la base pour déplacer l’unité d’entraînement et l’unité esclave de manière synchronisée vers l’objectif pour permettre à la roue entraînée et à la roue folle de s’appuyer contre la bague rotative dans des directions différentes, de sorte que la roue folle sera mise en rotation lorsque la roue entraînée entraîne la bague rotative en rotation.The present invention relates to a drive mechanism with a linear clamp for rotating a rotating ring of a lens on a camera comprising a base, a drive unit, a slave unit and a clamp unit, wherein the rotating ring can be a focus ring or a zoom ring. The camera is held on the base, while the drive unit and the slave unit are slidably arranged on the base and located on opposite sides of the lens. The drive unit includes at least one driven wheel, and the slave unit includes at least one idler wheel. The clamping unit is provided on the base to move the driving unit and the slave unit synchronously toward the lens to enable the driven wheel and the idler wheel to press against the rotating ring in different directions, so that the idler wheel will be rotated when the driven wheel drives the rotating ring to rotate.
