Two Sided Keyboard for a Data Terminal

A two-sided keyboard for a data terminal, shown in the figure, consists of a central box section 1 with two sloping surfaces 2a and 2b, shown in the end view, for the key layouts. The central box section 1 has end plates 3 shaped so that the keyboard may be turned over without depressing or damaging the keys. A cable 4 connects the keyboard to the data terminal (not shown).

The selection of one or another of the key layouts will depend on the application for which the data terminal is being used, for example, either data entry or word processing; either word processing or business accounting, etc.

Each of the key layouts has an indicator light 5 to indicate which of the key layouts should be used. The indicator light 5 may be set by the user by activating a recessed key 6. Alternatively, the indicator light may be set by the application program, and the user could activate the recessed key 6 to acknowledge that the keyboard is facing the right way and that the user is ready to use that application program. The acknowledgement can be handled within the keyboard logic and need not involve the application program itself. Both keyboard layouts can use the same keyboard logic and power supply.
