Abstract

PURPOSE:To prevent the deterioration of the adsorbing force, by making such that only the adsorbing port located at the position corresponding with the face to be adsorbed required for adsorbing a material will exhibit the absorving force. CONSTITUTION:A sliding valve 7 is provided on an adsorbing table body 1, and when a material to be adsorbed is placed the sliding valve 7 is lowered against the resilient force of a resilient member 8 to conduct the adsorbing port 2 to a vacuum pump. Consequently only the adsorbing port in the range required for the material to be adsorbed will exhibit the adsorbing force.
