Abstract

The flexible, opaque plastic cover for a keyboard superimposes a new, set of key indicia over the ordinary markings. A feature of some key operated machines is the rapid replacement of a type basket, cylinder or ball for the selective change of printed subject matter or a change of language. In the case of the IBM SELECTRIC* a change of type is readily effected by replacing the type ball.

Plastic Keyboard Translator

The flexible, opaque plastic cover for a keyboard superimposes a new, set of key indicia over the ordinary markings. A feature of some key operated machines is the rapid replacement of a type basket, cylinder or ball for the selective change of printed subject matter or a change of language. In the case of the IBM SELECTRIC* a change of type is readily effected by replacing the type ball.

When such a change is made, a related change of key markings is ordinarily not easy to make, since key tops must be changed or new labels added. In language teaching and translating, it is usually the case that the typist is not a touch typist in both languages and therefor key identification is needed.

The drawing shows a thin rubber or plastic sheet 10 suspended over a standard typewriter 11 before being lowered and either laid in place or fastened along the edges above the keyboard. The key top shapes are raised and molded in sheet 10 for definite unfastened positioning and also to aid the operator to see and feel the center of each key. The plastic telescopes enough under compression to allow free depression of the keys. A certain sheet 10 has keypad markings for a set of characters on a particular typeball 12 and is furnished with that typeball. Whenever the operator changes the typeball, the old translator sheet is lifted off and the new one is set in place. * Trademark
