The present invention includes a housing frame (30) including a screw drum (10) which is linked to the output of the speed reducer (12) by the motor (11) and is supported on the support plate (13) by the rotation shaft (15) and which winds and unwraps the stage driving wires (16)(16′) and a linear motion means (20) for screwing the rotary shaft 15 to convert the rotary motion into a linear motion, providing an inner space (31) accommodating the screw drum (10), and supporting the wires (16)(16′) for simultaneous winding or unwinding in front of and behind the screw drum (10); an LM guide (40) for guiding the longitudinal movement of the support plate (13) and the screw drum (10) by being provided at the upper and lower portions of the support plate (13) and inside the upper surface (30a) and the lower surface (30b) of the corresponding housing frame (30); a front pulley (100) provided at the front of the housing frame (30) to guide the wire (16) to the front of the screw drum (10); and a rear pulley portion (200) provided at the rear portion of the housing frame (30) to guide the wire (16′) to the rear of the screw drum (10), wherein the front pulley (100) and the rear pulley (200) are installed so that their upper and lower positions are opposite to each other so that both of the wires are simultaneously wound and unwound and both wires are used at two or more points with at least one wire (16) at the front and at least one wire (16′) at the rear.

    본 발명은 모터(11)에 의한 감속기(12) 출력에 연동하며 지지판(13)에 회전축(15)이 지지되며 무대 구동용 와이어(16)(16')를 감거나 푸는 스크류드럼(10)과, 회전축(15)과 나사결합하여 회전운동을 직선운동으로 변환시키는 직선운동수단(20)을 포함하고, 스크류드럼(10)을 수용하는 내부공간(31)을 제공하며, 상기 와이어(16)(16')를 스크류드럼(10)에 전후방에서 동시에 감거나 동시에 풀리도록 지지하는 하우징틀(30); 지지판(13)의 상하부 부위와 대응 하우징틀(30) 상부면(30a) 및 하부면(30b) 내측에 설치되어 지지판(13)과 스크류드럼(10)의 길이방향 이동을 안내하는 LM가이드(40); 스크류드럼(10)의 전방으로 와이어(16)를 안내하도록 하우징틀(30) 전방에 설치한 전방활차부(100); 및 스크류드럼(10)의 후방으로 와이어(16')를 안내하도록 하우징틀(30) 후방 부위에 설치한 후방활차부(200) 를 포함하며; 상기 전방활차부(100)와 후방활차부(200)는 상하 위치가 서로 반대로 설치되어 양 와이어가 동시에 감기고 동시에 풀리며, 양 와이어는 적어도 전방에 하나의 와이어(16), 후방에 적어도 하나의 와이어(16')로, 적어도 2포인트로 사용하는 것을 특징으로 한다.
