Abstract
An apparatus is provided for transferring disks with center holes such as semiconductor wafers from one cassette of an ordinary kind to another having a different pitch. The apparatus has an elongated rod on which an array of disk-shaped pieces each capable of supporting a wafer from its center hole is slidably mounted. These pieces are so connected that the separation between each of mutually adjacent pairs can vary but not to exceed a predetermined maximum distance. The piece at one end of the array is affixed to the rod and the one at the other end is attached to a power source and is moved along the rod.
