Claims

[Scope of utility model registration request]

It comprises at least one scale and a plurality of sliders attached to the scale so as to be movable relative to the scale, and a plurality of sliders are integrally connected to the scale in the horizontal direction, and each A linear pulse motor characterized in that the connected sliders are connected so as to advance at a constant pitch as a whole by sequentially applying pulse signals to the sliders.
