Film feed mechanism in a motion-picture camera |
摘要 |
A film mechanism for a motion-picture camera is provided. The film feed mechanism has a transport grip having a transport grip clip and at least one transport grip tip which engages in a sprocket hole of a motion-picture film that is transported at a predefinable film transport speed by the kinematics of the transport grip. The transport grip tip displaces the motion-picture film in an intermittent manner and runs through a closed trajectory whose reversing points determine the length of travel during the film transport. The kinematics of the transport grip can be dynamically and/or statically modified in accordance with the film transport speed by a modification to the relative positions of the transport grip and grip drive connected in an articulated manner to the transport grip in such a way that a constantly correct length of travel during a film transport step of the transport grip is guaranteed.
