Abstract:
1. A piezo-driven parts feeder that conveys parts by generating vibration with a vibration generator including an elastic member having a piezoelectric element mounted thereto to align the parts, comprising: a moving table having or supporting the parts conveying member; a fixed table disposed below the moving table, for supporting the moving table so as to freely vibrate the moving table through the vibration generator; the vibration generator including a first elastic member and a piezoelectric element mounted to the first elastic member, one end of the first elastic member being fixed to the moving table and the other end of the first elastic member being fixed to the fixed table; and a support member including a second elastic member different from the first elastic member, one end of the second elastic member being fixed to the moving table and the other end of the second elastic member being fixed to the fixed table, wherein the first elastic member is formed approximately in L-shape; wherein one side of the L-shape is arranged almost perpendicularly to the moving table and the fixed table; and wherein the other side of the L-shape is arranged almost in parallel to the moving table and extends from the edge of the one side of the L-shape closest to the moving table so as to extend toward a predetermined direction.
