Abstract
Abstract A mounting and biasing mechanism for maintaining an essentially constant tracking force between a frictionally driven wheel and a measurement surface, along which the wheel rolls, is described. The mechanism includes a base member and a carrier member having resilient means operatively coupled between them for biasing the carrier member relative to the base member along a predetermined path of movement defined for the carrier member. The predetermined path of movement of the carrier member is defined by flexure means connected between the base and carrier members. The flexure means is arranged to define three spaced laterally deflectable columns, aligned normal to the path of movement between the base and carrier members, to provide three essentially frictionless, highly compliant points of connection between the base and carrier members.
