1. An automatic musical instrument for automatically performing music in response to triggers generated by external operation in accordance with music data for automatic performance, comprising:
- a main body; and
a sliding operation piece that is operated to slidably move in contact with said main body, wherein said main body comprises;
a speed measuring unit operable to measure the sliding speed of said sliding operation piece;
a direction detecting unit operable to detect the sliding direction of said sliding operation piece; and
a trigger generating unit operable to generate a trigger for automatic performance in response to detecting change of the sliding direction of said sliding operation piece and the sliding speed of said sliding operation piece exceeding a first predetermined threshold value.

Abstract
When the sliding direction of a sliding operation piece (40) is changed while the sliding speed thereof exceeds a threshold value, a trigger is generated to start sound output. The termination process of the sound output started in response to the latest trigger is invoked when the sliding speed of the sliding operation piece (40) falls below a threshold value, while, when a new trigger is generated, the termination process of the sound output started in response to the previous trigger is invoked.

21. An automatic musical instrument for automatically performing music comprising:
-
a first member formed with a periodic pattern configured to modify the intensities of light rays reflected from said periodic pattern;
a second member that is moved in the vicinity of said first member relative to said first member by external operation and is provided with an optical device capable of directing light rays to said periodic pattern in two positions apart from each other by a distance differing from any integer multiple of the half period of said periodic pattern along the direction of the relative movement of said second member; and
a signal processing circuit that receives the light rays reflected from said periodic pattern, detects the intensities of the light rays, determines the direction of relative movement of said second member relative to said first member on the basis of the differential phase between the intensities of the light rays, generates a trigger when the direction of relative movement of said second member is changed, and outputs an audio signal in response to said trigger in accordance with music data for automatic performance.
