摘要： A scale arrangement is designed for monitoring relative displacement between first and second members. The scale arrangement comprises an elongated scale having end portions at both ends thereof, a pair of receptacles respectively receiving the end portions, a hollow member receiving the scale therein, the hollow member being formed into essentially quadrate cross section, a head slidingly mounted on the scale for axial movement therealong for reading scale to generate a read scale indicative signal, a head slider associated with the head for axial movement with the head, the end portions, the receptacles and the head sliders being positioned on respectively associated one of first and second members with respect to the end portions, position of the head slider being determined with respect to a reference plane set on the outer peripheral plane on the hollow member in relation to the end portion.

摘要： A magnetic linear scale unit comprises a magnetic scale and mounting blocks which are designed to be rigidly fixed to one of relatively displaceable mechanical components, about which magnitude or stroke of the relative thrusting displacement is to be measured. The magnetic scale has end sections to be mounted on the mounting blocks. The end sections have round peripheral portion mating with the mounting block. At least one of the end section also includes a structural component which allows pivotal movement of the magnetic scale relative to the mounting block for fine adjustment of the axis of the magnetic scale relative to the axis of relative movement of the mechanical components. A scale channel is free from the mounting block and simply serves as the magnetic shield. Therefore, the scale channel of the invention is substantially free from the accuracy requirement and production error of the scale channel and will never affect measurement of the displacement magnitude.
