Electronic apparatus for high-speed writing on electronic typewriters, printers, photocomposers, processors and the like.

摘要

The equipment comprises at least a keyboard for abbreviated, simultaneous keying of several letters or numbars by the operator. The keyboard is divided into 8 operating sectors making possible simultaneous, abbreviated keying, according to a determined code, of words or parts of words, so that they can be written by a single stroke at high speed (about 1,200 characters per minute), i.e. greater than the speed possible on a traditional keyboard, with possible prior recording, automatically transcribed by a decoder, in an orthographically and linquistically correct and complete. i.e.. unabbreviated form, on electronic typewriter, incorporated or external printers, photocomposers, processors and the like. The keyboard comprises 8 operating sectors, 4 for the right h and (b2, c1, c2, c3) and 4 for the left hand (a1, a2, a3, b1) and further comprises a sector for special operating commands (c4) and one (d) for commands to external equipment. A microprocessor sequentially scans the keyboard and memorizes the pressed keys, then proceeds to decoding the combination and memorizing them.
