An electro-optical signal transmission module for transmitting an information signal between stationary and moving objects (such as the stationary and moving components of a rotary magnetic head scanner). The module has complementary mating structure to facilitate the stacking of a plurality of modules together, so that a plurality of separate information signals may be transmitted between relatively moving bodies.
