摘要

A module storage rack is disclosed e.g. a probe rack suitable for use with a carrier e.g. a probe measurement head which is movable relative to the rack for picking a module from the rack. The rack comprises a base member and a plurality of storage ports connected to the base for storing the modules, each port having an actuatable connecting or disconnecting tool for connecting or disconnecting a module to or from the carrier, and each storage port being movable relative to the base member the said relative movement providing the actuation of the tool wherein the said plurality of storage ports are movable together relative to the base. Additionally, there is disclosed a linkage having a plurality of pivotally interconnected rigid members being connected to the tool for causing the tool to connect or disconnect the module to or from the carrier. The linkage may be operated by movement of the rack or by alternative means.
