Abstract: An ascending/descending batten device raised and lowered to/from a space above a ceiling, including: a body for mounting various effect equipment providing video, lighting, and sound; a roller part rotatably mounted on the top surface of the body; a pair of wires having one end fixed to the left and right sides of the roller part and the other end thereof fixed to an arbitrary structure in the space above the ceiling, the pair of wires being wound or unwound by the rotation of the roller part; a driver mounted on the body to rotate the roller part forwardly and backwardly; and a foldable cable housing part for accommodating a power line or signal line connected to the effect equipment thereinto and having both ends fixed to the body and the arbitrary structure in the space above the ceiling and a plurality of articulated portions hinge-connected to each other.

Abstract: The present invention relates to a movable table for a projector including: an upper plate having an inclination adjustment plate disposed on top surface thereof in such a manner as to be adjusted in an angle relative to a horizontal plane; a pair of vertical members extended downward from both ends of one side edge of the upper plate in such a manner as to form the legs of the upper plate; a pair of horizontal members extended horizontally from the underside of the pair of vertical members; caster wheels disposed on free ends of the horizontal members and on the undersides of the vertical members: and levelers located adjacent to the caster wheels disposed on the undersides of the pair of vertical members and each having a stroke in a range of separating the caster wheels from the floor.

Abstract: Disclosed herein is a rig for multi-camera photographing. The rig for multi-camera photographing includes a cover frame, a center base plate fixed and installed in a center line over the cover frame, and a left rotational movement plate and a right rotational movement plate disposed on the left and right sides of the center base plate and disposed in such a way as to rotatably move around rotational movement shafts protruded over the cover frame.
