Abstract

1521435 Keyboard button manufacture photographically IBM UNITED KINGDOM Ltd 24 Feb 1977 07823/77 Heading G2X Keyboard buttons are manufactured by assembling blank buttons each having a surface on which a character is to be deposited; cleaning the surface of each button chemically; coating the surface of each button with a layer of radiation-sensitive material, e.g. photo-resist material; exposing the surface of each button to radiation to produce a latent image of a selected character; developing the exposed layer to provide the selected character; and coating each character-bearing surface with a transparent protective layer. A preferred manufacturing scheme is illustrated in Fig. 4.
