Non-oral communication device
First Claim
1. A non-oral communication device comprising:
- a single electrical switch actuable by an operator and movable between a first and a second position;
a memory for storing a plurality of plural word messages at a plurality of locations indexed by plural digit numbers, said memory being capable of storing said messages at locations indexed by numbers having at least three digits;
a selector circuit for selecting one of said plural word messages by its indexed plural digit number;
said selector circuit including numeral display means actuated by said switch, said numeral display means having at least three digit locations at which numerals can be displayed, means for cyclically indicating different numerals at each of said at least three digit locations, means actuated by said switch for choosing a displayed numeral at each of said at least three digit locations, said cyclical indicating means cyclically indicating different numerals at one of said at least three digit locations until said switch actuates said choosing means to choose a numeral being indicated, said numeral display means displaying a numeral chosen, said cyclical indicating means cyclically indicating different numerals at a succeeding digit location after a numeral has been chosen at a preceding digit location, and means actuated by said switch for transmitting the numerals chosen to said memory after a complete plural digit number of a desired plural word message has been chosen; and
means for signaling a message display means to display a selected plural word message indexed by a chosen plural digit number.

Abstract
A non-oral communication device is disclosed. The device includes a single electrical switch actuable by an operator and movable between a first and second position. A memory stores a plurality of messages at a plurality of locations indexed by plural digit numbers. A selector circuit is provided for selecting one of the messages by its indexed plural digit number. The selector circuit includes a numeral display actuated by the switch. The numeral display has a plurality of digit locations at which numerals can be displayed. A mechanism cyclically displays different numerals at each digit location. A mechanism actuated by the switch is provided for choosing a displayed numeral at each digit location. A mechanism actuated by the switch transmits the numerals chosen to the memory after a complete plural digit number of a desired message has been chosen. A signalling mechanism signals a message display to display a selected message indexed by a chosen plural digit number.
