との間に直列接続してなるキー入力装置。 Keys for data input such as numeric keys, character keys or symbol keys, keys for switching between uppercase and lowercase letters, keys for mutually converting alphanumeric characters and kana characters, keys for simultaneous pressing such as shift keys and control keys The key input device is equipped with a plurality of signal generators that output frequency signals respectively corresponding to sounds of different pitches, and each of these signal generators is connected to a surrounding area of each of the data input keys. The key is assigned and divided so that adjacent keys belong to different key groups, and is driven by the operation of each key of a plurality of key groups individually corresponding to each signal generator, and only when the switching key is operated. a frequency conversion circuit that is driven to convert the frequency of the output frequency signal of one of the signal generators; and a frequency conversion circuit that is driven only when the simultaneous press key is operated to convert the output frequency signal of one of the signal generators to a predetermined frequency. A key input device comprising a waveform synthesis circuit for synthesizing waveforms connected in series between an output terminal of each of the signal generators and a key identification sound output generator.
