DISPLACEMENT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a displacement measuring device superior in durability in which gap adjustments are easy and which indicates slide characteristics. SOLUTION: In a static-capacitance-type encoder with a scale member 1 and sensor head 2 opposed to the scale member 1 in such a way as to be relatively moved, sliding films 24 worked into a predetermined pattern are arranged at a plurality of locations in a flat surface avoiding the transmitting electrode part 21 and receiving electrode parts 22 of the sensor head 2.
