摘要：
To ensure an energy-efficient transfer of light signals between two elements of a machine which are movable relative to one another, a device and a method for transferring light signals between such elements is provided. A first element has a plurality of light sources for delivering light signals and a second element has at least one photoreceiver for receiving the light signals. A unit causing the turning on or off is configured such as to effect a turning on or off of only one portion of the light sources.
