Displacement detecting device power supply and data communication device
First Claim
1. A displacement detecting device for detecting a relative displacement between a first member and a second member, wherein said first member includes a first output connector for outputting a displacement signal based upon the relative displacement, and said second member includes a second output connector for outputting the displacement signal, and wherein the first and second output connectors are adapted to be connected to a receiving-side connector that receives the output displacement signal.

Abstract
A scale and a detecting head each include input/output connectors. Either of the input/output connectors is connected to receiving-side connector. By connecting the receiving-side connector to either of the scale and the detecting head, which is fixed in use, there is no change that a receiving-side cable will be disconnected by movement of the counterpart of the fixed member. This results in improvement of the reliability. Additionally, device is operable at high speed since the cable does not restrict motion of the movable member.
