Abstract
An electronic hi-hat 1 has a rod movable up and down with an operation of a player. A top cymbal 2 has a striking surface that can be struck by the player. A bottom cymbal 3 comes into contact with or separates from the top cymbal 2. An optical sensor 7 detects separation dimension between the top cymbal 2 and the bottom cymbal 3. The optical sensor 7 detects separation dimensions of a plurality of areas that are displaced with inclinations of the top cymbal 2 and the bottom cymbal 3 with respect to the rod r. The plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal 2 and the bottom cymbal 3 around the rod r as a center.
