Apparatus for pivotally orienting a projection device

An apparatus that provides for rotation about two axes orthogonal to each other includes a gimbal having two arms adjoining a portion that is mounted to a base for rotation about a first axis. A shaft defining a second axis orthogonal to the first pivotally couples a mounting plate to the arms. The mounting plate has an arcuate edge with first and second parallel grooves therein adapted to receiving a drive cable. A drive cable that is engaged with a drive pulley is aligned by at least one idler pulley with the first and second grooves of the mounting plate. The drive cable has opposing free ends that are received in the first and second grooves of the mounting plate. A motor is coupled to the drive pulley for controlling the drive cable travel, to accordingly rotate the mounting plate to provide for orientating a device in a desired direction.
