Abstract

An electronic musical instrument of the string-plucking type which does not create a large time lag from when the musical instrument is operated until when the sound is produced, and does not cause a detection mechanism to become complex. A photo sensor ( ) for being operated by a player is provided in a main body ( ) that is formed in a shape resembling a string-plucking musical instrument. The photo sensor ( ) generates a signal for producing sound when the light emitted from a light-emitting unit ( ) to a light-receiving unit ( ) is not detected by the light-receiving unit ( ). A detection signal from the photo sensor ( ) needs not be put to the conversion processing, and the time can be shortened from when the musical instrument is operated until when the sound is produced. Since light is used, the constitution of the detection mechanism does not become complex.
