Abstract
Abstract An optical encoding apparatus in which selected ones of a number of light conducting members are illuminated by a movable, independently selectable member, is disclosed. This movable member carries a coded array of illuminating areas. Photosensitive devices are associated with each of the light conductive members to indicate the illuminated condition of a given member, or array of members, in response to their being illuminated by the illuminating areas of the movable member. These photosensitive devices provide a coded output signal in the form of voltage or current information for use by other equipment which may utilize or be responsive to, or transmit the coded signals so produced.
