Data selection and display arrangement for a small device
First Claim
1. For use with an electronic calculator through which operations on selected numeric data are performed in accordance with selected functions after entry of the data and functions to produce operational outputs, a selector and display arrangment comprising a casing having a dial face enclosed by a peripheralportion, scale means mounted on the dial face adjacent said peripheral portion bearing indicia corresponding to the numeric data and the functions, at least two display devices for respectively displaying said indicia and the operational outputs, means mounting the display devices in the casing for display of the indicia and the operational outputs on separate displaying areas of the dial face, pressure responsive key means for initial selection of the indicia and subsequent entry of the corresponding numeric data and functions into the calculator, means movably mounting the key means for displacement to different operative positions along the scale means to effect said initial selection and display of the selected indicia on at least one of the said displaying areas prior to entry of the corresponding data and functions into the calculator, and means responsive to pressure exerted on the key means in each of said different positions thereof for said subsequent entry of the selected data and functions to effect display of the operational outputs in another of the displaying areas.

Abstract
A selection and display arrangement for a small computer such as one capable of being worn on the wrist and having a dial face. To facilitate accurate entry of the digital and computational function data, display windows are separately provided on the dial face of the computer to display separately the selected digital and function selected data. An additional display window displays the computational result. The dial face carries indicia along its periphery representing the selectable data. Movable key means is mounted for movement around the periphery of the dial face, such that once positioned adjacent the location of a desired data item, a transverse movement of the key means accomplishes data entry.
