Scale for use with a displacement sensor

摘要

A scale, which is provided for use with a displacement sensor, has a high degree of freedom and is capable of being manufactured at a low cost. The scale includes a graduation section and a base board which is formed separately from the graduation section and which is bonded to the graduation section. By bonding a graduation section to a separate base board, a single graduation section can be used for scales of varying lengths. Sufficient rigidity is provided by bonding a separate base board to the graduation section.
