Means for encoding ideographic characters
First Claim
1. Apparatus for encoding Chinese type characters in accordance with their basic stroke type and sequence comprising a keyboard having a plurality of up to eight inclusive of monographic keys, and a plurality of digraphic keys, key responsive means responsive to the actuation of each said monographic key for generating a code signal representative of a basic stroke and to the actuation of each said digraphic key for generating a code signal representative of a sequence of said basic strokes of two.

Abstract
A word processing system for Chinese type characters includes a keyboard with a generally standard key arrangement for encoding the characters in accordance with their basic stroke type and sequence. Up to eight basic stroke types may be employed, although a five stroke system is preferred. Recurrent code sequences of two, three, four and five strokes are identified. An "end of character" code may be generated with the space bar. Preferred sequences are assigned key positions so as to provide an ergonometrically efficient keyboard. Average typing speeds using the keyboard are comparable on a character/word basis to those for English.

- 12. A keyboard for encoding Chinese type characters in accordance with five basic strokes and the sequence thereof comprising three horizontal ranks, each rank comprising about ten keys wherein all character coding keys locate, wherein five said keys locating in positions in the middle rank are monographic and representative of a basic stroke, and about twenty three said keys are polygraphic, representative of a sequence of basic strokes of two or more, at least a portion of said polygraphic keys being digraphic, means responsive to the actuation of said keys to generate a code signal representative of the stroke or sequence of strokes represented thereby.
