Abstract
In a device for the transmission of information between two apparatus parts which rotate relative to each other with the use of a modulated luminous flux and a photosensitive receiving means, it is seen to it, by the introduction of diaphragms within the ray path that the modulated luminous flux does not strike the receiving means directly. In this way the radiation flow received with constant transmission signal by the receiving means is prevented from experiencing modulation upon rotation of the two apparatus parts with respect to each other.
