PURPOSE:To make running at a corner section smooth by providing a driving runner which is capable of rolling along a driving rail, above a support runner provided for the upper section of a partitioning panel, and thereby interposing a rotatable connecting shaft between both of the runners. CONSTITUTION:When a light from the wall side of a housing chamber is sensed by a partitioning photo-electric tube 46, a running motor 2 is drivingly rotated. The rotation of a rotating shaft 5 is transmitted to rotating shafts 6a and 6b, and furthermore, a vertical shaft 14 is rotated via bevel gears 17a, 17b and 16. Following which, the rotation of the vertical shaft 14 is transmitted to the driving roller 23 of a driving runner 18 via a connecting shaft 19, and the roller 23 is rotated while the wall 34a of a driving rail 34 is being pressed, so that a partitioning panel 1 is thereby moved. When the panel 1 reaches a corner section, the runner 18 is moved along the circular arc section of the rail 34, and a runner 3 is thereby moved along the right angle section of a supporting rail 36. Furthermore, the sloping angle of the connecting shaft 19 is made larger, and the upper and lower connecting shafts of the connecting shaft 19 are moved as to be gradually parted as they are parted from the corner section. |
