ABSTRACT:
An apparatus for maintaining a positioning force on movable parts within a guide means, such as a scanning carriage mounted within a hollow body in an incremental measuring system. The positioning apparatus includes a leaf spring for mounting a pressure roller wherein the leaf spring is provided with at least one slot and the roller-mounting end of the leaf spring is forked. The pressure roller is thereby adjustable so that a rolling surface of the pressure roller remains in parallel alignment with a surface of the guide means.
