ABSTRACT:
Apparatus for processing a menu device comprising a card; bubbles on the card having positions corresponding to selectable data; each bubble having a first position projecting upwardly from the plane of the card, and a second position into which it is displaced relative to the plane of the card, by finger pressure, to indicate selection of data corresponding to bubble position on the card, the apparatus comprising first structure for detecting which of the bubbles are so displaced, and; second structure to engage displaced bubbles and to urge them back toward the first positions after the first structure detects which of the bubbles are displaced to second positions.
