International ClassB41J 005/10AbstractKeyboards structured to accommodate electronic technology advances evidenced this past seven years involving keyboards for personal and home use on computers typewriters, personal home computers, calculator and chording keyboards and other typographical equipment are disclosed. A plurality of different designs utilize 26 letters of the English alphabet in a keyboard configuration of at least two rows and an unlimited number of keys. The vowels are separated from the consonants and placed on different rows; thereafter, vowels and punctuation appear on the same row completing one design. In some of the keyboards of the invention all of the vowels are separated from the consonants and in others only a few vowels are separated from the consonants and punctuation keys may be located anywhere on the keyboard. The alphabet is always in its natural sequential order. Color can be used as an identifying aid. These keyboards are intended for nontypists and physically handicapped people.
