1. A defibrated material manufacturing device configured to defibrate a feedstock of clumps of shreds containing fiber into defibrated material, the defibrated material manufacturing device comprising:
a conveyance device configured to convey the feedstock by vibration, and to discharge the feedstock, the conveyance device including a vibratory linear feeder including
a base on which the feedstock is disposed, and
a drive device configured to vibrate the base;
a removal device configured to remove at least a part of foreign matter contained in the feedstock, the removal device having
a first magnet configured to attract at least the part of the foreign matter, the first magnet being disposed below the conveyance device so that an upper side of the first magnet contacts the feedstock dropping from the conveyance device in a direction of gravity, and
a rotating shaft rotationally supporting the first magnet so that the first magnet rotates due to a moment produced by a weight of the part of the foreign matter attached to the first magnet, the first magnet extending along an axial direction of the rotating shaft;
a metering device configured to measure the feedstock that has passed the removal device;
a storage device configured to store a measured feedstock measured by the metering device; and
a defibrator configured to defibrate the measured feedstock supplied from the storage device into the defibrated material.
