Filed: 1982-03-08
Abstract: PURPOSE:To decrease the number of keys and to reduce the weight of a key input device, by providing selection keys for input of KANA (Japanese syllabary) letters and alphabet letters, using some of other alphabet keys also to numeric keys and supplying KANA in the form of romaji (Roman character). CONSTITUTION:The keys 4 and 5 designate the input of both KANA letters and alphabet letters. In addition, 26 alphabet keys (A-Z), an entry key 20 and a clear key 19 are provided (30 keys in all). Some of the alphabet keys are used also to numeric keys as shown in the diagram. When a desired alphabet key is pushed after pushing ALPHA key 5, a discriminating circuit (not shown in the diagram) discriminates the input of alphabet letters and delivers alphabet letters. For instance, keys ''K'' and ''A'' are pushed for KANA ''KA'' after pushing KANA key 4. Thus the discriminating circuit discriminates the input of KANA letters and delivers ''KA'' with combination of K and A. The numeric characters are fed directly without pushing a discrimination key. KANA ''UN'', a voiced spot and a semi-voiced spot are defined as NN, ZZ and PP, respectively. As a result, the number of keys is decreased to reduce the weight of a key input device.
