リニアスケール。 A case equipped with a rotary encoder in which a gear is attached to a rotating shaft and a rail on which a rack is formed are respectively attached to two objects that move linearly relative to each other, and the gear and the rack on the rail are engaged. In addition, in the linear scale, the relative movement between the objects is converted into rotation of the rotary encoder, and a signal corresponding to the amount of movement is obtained from the rotary encoder. A linear scale, characterized in that the gear is held against the rack and pressed within a predetermined load range.
