Abstract:
1. A digital displacement measuring instrument comprising: a main body; a spindle slidably provided at the main body; an encoder accommodated in the main body for detecting displacement of the spindle to convert a value for the detected displacement to an electric signal, the encoder having a rotor rotating in a peripheral direction of the spindle and a stator provided inside the main body at a position opposite to the rotor with a prespecified space therefrom; a support member provided at an edge of the main body for supporting the spindle in the longitudinal direction thereof; an adjustment member provided on the support member for positioning the rotor; and an elastic member for biasing the stator toward the rotor, wherein the stator is directly or indirectly via other component hooked in the main body at a position away with a prespecified space from the spindle.
