ABSTRACT:
A covering mechanism for covering an area in which a movable table, etc. of, for example, semiconductor assembling machines using a flexible sheet cover that has elasticity. One end of the cover is fastened to a take-up shaft and the other end to a movable member that moves over the movable table, etc. in the direction perpendicular to the take-up shaft. The cover wrapped around the take-up shaft is stretched out when the movable member is moved away from the take-up shaft, thus covering the table. When the movable member is moved towards the take-up shaft, the cover, with the elasticity, is back to be wrapped around the take-up shaft. By arranging a plurality of take-up shafts at right angles, the covers can stretch in the directions perpendicular to each other, thus covering a wider area in which an X-Y table is moved around.
