Camera support apparatus

摘要

A camera support apparatus for supporting a video camera comprises a drive train device (1), a first inductive position sensor (23), (14) attached to a rotational output device (11) of the drive train device (10), and a second inductive position sensor (2), (3) attached to a rotational input device (4) which is operably connected to the drive train device (1), whereby the inductance sensed by the first position sensor (23), (14) is indicative of the rotational displacement of the rotational output device (11) and the inductance sensed by the second position sensor (2), (3) is indicative of the rotational displacement of the rotational input device (4).

1. A camera support apparatus, which in use supports a video camera, the apparatus comprising a means of moving the supported camera along an axis and an inductive position sensor attached to said apparatus, whereby the inductance sensed by said inductive position sensor is indicative of the displacement of said supported camera, the apparatus further comprising a drive train which incorporates respective successive drive stages coupled together by means for causing rotational velocity of a rotational movement to be reduced across the drive stages thereby converting torque applied to an input of each drive stage into an increased torque at an out-put of each drive stage, whereby one said successive drive stage incorporates a gear drive, wherein prior to said gear drive is another said stage incorporating a belt drive.
