Carrier mechanism for supporting and moving traveling module

Abstract

A carrier mechanism for supporting and moving a travelling module along a predetermined travelling path is disclosed. The carrier mechanism includes a guide device fixed inside a casing, a carrier movable along the guide device between a forward and rearward positions with the travelling module removably mounted on the carrier and a driving mechanism including a motor mounted to the carrier and in driving engagement with the guide device for moving the carrier between the forward and rearward positions. The guide device includes an elongate strip integrally formed on a bottom of the casing with a rack formed along a side face thereof to drivingly engage a pinion of the motor. Alternatively, a timing belt and toothed wheel system or a wire and pulley system or a worm and gear system may be used to replace the pinion and rack system.
