1. A fiber body manufacturing apparatus comprising: a material supplier that supplies a material containing a fiber; a defibrator that is arranged downstream relative to the material supplier in a transport direction of the material and defibrates the material supplied from the material supplier; a separation section that is arranged downstream relative to the defibrator in a transport direction of a defibrated material generated in the defibrator, and includes a rotating member having a first surface and a second surface that are in a front and back relationship, and being at least partially composed of a mesh, the defibrated material being supplied onto the first surface, a first suction portion being arranged on a side of the second surface of the rotating member and facing the second surface of the rotating member, the first suction portion sucking the defibrated material via the mesh to remove foreign matter, a collector that includes a second suction portion which is arranged on a side of the first surface of the rotating member and faces the first surface of the rotating member, the collector collecting the defibrated material from which the foreign matter on the first surface was removed; an accumulation section that is arranged downstream relative to the separation section in the transport direction of the defibrated material, and accumulates the defibrated material from which the foreign matter was removed to generate an accumulation material; a forming section that is arranged downstream relative to the accumulation section in the transport direction of the accumulated material and forms the accumulated material to obtain a sheet; a thickness detector that is arranged downstream relative to the forming section in the transport direction of the sheet and detects a thickness of the sheet; and a controller that is electrically connected to the separation section and the thickness detector, and controls an operation of the separation section based on a detection result of the thickness detector.
