Abstract
A multi-item data input apparatus for manual generation of data to designate selected ones of a plurality of items comprises lists of items visibly written in matrix array form on a number of sheets, with the sheets being rolled around a cylindrical holder in successively overlapping relationship. Means are provided for unrolling a selected one of the sheets such as to position the corresponding item array below a keyboard having a transparent key above each item. Actuation of a key causes an electrical signal designating the corresponding item to be generated.
