<p>PROBLEM TO BE SOLVED: To prevent variations in the generation timing of musical tones during key touch, even if variations in the accuracy of components in production occurs, and to improve the repeated playing. SOLUTION: Keys 2 turnably disposed on a keyboard chassis 1 are elastically provided with elastic hitting sections 7. The elastic hitting sections 7 are elastically deformed according to key touch force to thrust switch members 4. Accordingly, even if variations occur in the accuracy of the components, such as the keys 2 and the switching members 4, the generation timing of the musical tones during normal playing is set to the positions slightly lower than the positions, where the keys 2 are pushed in most deeply according to the elastic force of the elastic hitting sections 7, by which the variations in the generation timing of the musical tones in the key touch are prevented. More particularly the elastic hitting sections 7 are elastically deformed, when the keys 2 are strongly touched, by which the musical tones are generated when the keys 2 are most deeply pushed in, so that repeated playing to repeatedly touch the same keys 2 is carried out at a high speed and the repeated playability is improved.</p> |
