Zusammenfassung:	PURPOSE: An automatic scissors is provided to automatically open blades by detecting the variation of load applied to the scissors. CONSTITUTION: A control unit calculates a control signal, and generates a control order. A motor(20) is driven by the control order. A cylindrical cam(40) is connected to the motor by a planetary gear speed reducer(30), and rotates. The cylindrical cam has a closed-loop pitch groove(45), and converts a rotary motion into an arc motion. A fixed blade(75) is fixed on a body. A movable blade(71) is coupled with the fixed blade by a shaft(76), and is connected to the pitch groove. The movable blade receives the rotary motion of the cylindrical cam, and moves up and down.
