Data input apparatus










Image Number 4 for United States Patent #4274081.

A data input apparatus comprises a display device for displaying guidance information which designates types of data to be inputted as well as the order therefor, a key set having a plurality of keys arrayed in a matrix and a corresponding number of mats defining the functions of the individual keys which can be imparted with new definitions by changing over the associated mats, and a circuit adapted to select and change the mats defining the keys so that the various types of data indicated by the guidance information can be inputted in the order given by the guidance information. The mats can thus be replaced by other proper ones automatically without resorting to manual operation.
