ABSTRACT:
A device for controlling the raising and lowering of a fluidized bed for supporting a human body on a bed of particles which can be made to float and flow by supplying air under pressure thereto. A drive unit vertically raises or lowers the bed in response to a vertical movement command issued by a control unit. A flow stop command is issued for stopping the operation of an air compressor, which floats the beads, when the vertical movement command is generated. The vertical movement command is inhibited during a predetermined interval after the command has been generated in order for the flow of compressed air to stop to allow the beads to come to rest before the bed is raised or lowered.
