Abstract
A data processing terminal device includes a substantially enclosed optical chamber which serves as a wireless communication 'bus' between pluggable functional units such as a controller unit, printer units, display units, etc. Each functional unit includes a transducer having an emitter component for injecting optical energy into the cavity and a detector component for sensing optical energy injected by transducers of other functional units. The energy distribution within the cavity is shaped by elliptic parabolic reflectors, preferably molded integrally with the floor of the chamber structure.
