Motion control device

摘要

Described herein is a motion control apparatus for a camera and methods of use of the apparatus. The apparatus includes a camera attachment and a linear movement assembly operatively associated with a drive mechanism. This configuration causes linear movement of the drive mechanism and the camera attachment in a linear direction along a line or pathway. The apparatus is used for capturing time delay sequences and allows for operation over any desired path length along the line. Further, the apparatus is portable and can be used with other camera accessories.

1. A motion control apparatus for a camera wherein the apparatus includes:
a camera attachment for mounting the camera; a drive mechanism linked to the camera attachment; a linear movement assembly including a drive pulley wherein the drive pulley is operatively associated with the drive mechanism; and a line; wherein in use, the line is wound around the full circumference of the drive pulley and the drive pulley is driven by the drive mechanism, such that actuation of the drive pulley by the drive mechanism causes linear movement of the drive mechanism and the camera attachment in a linear direction along the line; wherein the linear movement assembly is mounted to a support apparatus which includes a camera slider, camera dolly, camera jib arm or cable cam; and wherein the line passes through the linear movement assembly under a lowest positioned rib of a ribbed roller located on a periphery of the linear movement assembly, then winds around the full circumference of the drive pulley before exiting the linear movement assembly over the top of the ribbed roller thereby passing over the drive pulley and flat rollers located on the periphery of the linear movement assembly, wherein the flat rollers are on an opposing side to the ribbed rollers.
