A nesting table comprises a frame, a table top that rotates between a use configuration and a storage configuration, and a control means that controls the rate of rotation from the use configuration to the storage configuration. The multiple rate control circuit further outputs control signal LPFOUT for changing a multiple rate so that the PLL clock signal generation circuit does not deviate from a region capable of locking when being detected of deviation from the region capable of locking by detecting the state of reference voltage. When a request for document production is received, the image logs are automatically filtered through at least one classifier trained to return documents responsive to the document request, and documents corresponding to the filtered out image logs are output. The apparatus is equipped with a suction device that permits the sprayed-on treatment medium to be suctioned off from the top surface of the printed circuit boards during the spray process.
