Abstract
PURPOSE: To make it possible to obtain a measured length value under constant measurement pressure all the time by applying the measurement pressure without reference to a measurement range as well as a zero adjustment, by using a magnetic attaching-detaching mechanism and spring for the measurement-pressure applying mechanism of a linear digital micrometer.
CONSTITUTION: For a zero adjustment, lifter 8 is pulled in direction L to make spindle flank 1a in contact with anvil flank 2a, and consequently magnetic switch 10 operates to reset an outside counter. Next, a body to be measured is placed between flanks 1a and 2a and magnetic switch 10 is operated to apply measurement pressure through the action of magnetic-generating body 9 and a spring, so that the output of scale head 5 will be held at the point of fixed measurement pressure.
