Abstract
A surface texture measuring instrument has a pre-load leaf spring ( ) for biasing a detector ( ) having a skid ( ) at a distal end thereof, a pre-load force controller ( ) for controlling a pre-load force of the pre-load leaf spring ( ), and a stopper ( ) for restricting movement of the detector ( ) in a biasing direction when a predetermined pre-load force is applied to the detector ( ) by the pre-load force controller ( ). In conducting a skidless measurement, the detector ( ) is locked by applying the predetermined pre-load force to the detector ( ) by the pre-load force controller ( ). In conducting a skid measurement, the pre-load force less than the predetermined value is applied to the detector ( ) by the pre-load force controller ( ).
