ABSTRACT:
A changeable exhibitor, with or without keyboard structure, is rendered self-restoring by use of a flexible strip arranged to lie in a selectable looped position indicative of the data being exhibited or being entered into an associated data processing system. The strip is fixed adjacent its ends and overlies a series of aligned apertures in a base. The strip is longer than the distance between its fixed ends so that it will loop into one of the apertures, one being provided for each data bit. As a different part of the strip is looped by a stylus, depressible key, or the like, into a different one of the apertures to exhibit or enter a different data bit, the first loop is concurrently and automatically recalled. A plurality of parallel independently flexible strips are arranged as a matrix exhibitor/keyboard, and bands of alternate colors aid in visually distinguishing the entered data from the unentered data. Loops in flexible strips of metal can form part of a capacitive or magnetic coupling path from an interrogation means to a transducer.
