Abstract
A linear encoder for measuring a relative position of two objects displaceable relative to each other, including a scale for being secured on one of the objects and formed of a graduation carrying measuring standard and a measuring standard support, and a device for scanning the scale and securable on another of the objects, with the measuring standard support having two regions, which are spaced from each other in a direction of a longitudinal extent of the measuring standard for supporting the measuring standard, one of supporting regions forming a stationary support area and another of the supporting regions forms an elastic support area, and with the stationary and elastic support areas being formed as substantially continuous or interrupted linear support areas extending transverse to the longitudinal extent of the measuring standard.
