ABSTRACT:
A communications device including a display panel having a plurality of symbols arrayed thereon in a circle, each of the symbols indicating a particular idea to be communicated, and a pointer projecting radially from the center of the circle. An indexing mechanism is provided for producing incremental relative rotational movement between the pointer and the display to cause the pointer to be aligned with the next successive one of the symbols upon receiving a single manual input. Preferably, there are two display panels facing in opposite directions and a pointer corresponding to each panel. Each symbol on one panel has counterpart on the other and the pointers move in synchronization.
