摘要：
A conveying mechanism, for example, for moving each of a multiplicity of display devices through both a viewing area and a storage area. In the embodiment described herein, the mechanism includes a first and second sprocket wheel of different diameters mounted for rotation about a common axis at a common angular speed, first and second endless chains trained about the wheels and first and second drive means on the two chains for engaging a carrier assembly and moving it along the first chain at the speed of that chain and along the second chain at the speed of that chain.
