KEYBOARD SYSTEM FOR CHINESE CHARACTER TELEPRINTER, CHINESE CHARACTER TYPEWRITER, MONOTYPE ETC.

摘要

A teleprinter apparatus for producing pairs of seven element code units which together represent a character or symbol, such as a Chinese character. The apparatus has a keyboard much like the keyboard of a conventional teleprinter or typewriter for typing Roman letters, numbers and symbols, and the keyboard is connected to conventional apparatus for producing seven element code units each time a key is depressed. As a guide to the pairs of keys which are to be depressed to produce desired pairs of code units for representing the desired character, there is provided a character board which has two sets of blocks thereon. Each set has the same number of blocks as there are keys, and each block in each set corresponds to an individual key character. The blocks are in the same arrangement as the arrangement of the keys. Each of the blocks in one set has therein a plurality of characters for which code units are produced, and the characters are arranged in the same pattern as the pattern of the keys on one half of the keyboard. Each of the blocks in the other set has the characters arranged therein in the same pattern as the keys on the other half of the keyboard. A character for which the code units are to be produced is located in one of the blocks on the character board, and the key corresponding to the block is actuated to produce the first code unit and then the key corresponding to the position of the character in the block is actuated to produce the second code unit.
