1. A fibrous body processing apparatus, comprising:
a coarsely-crushed-pieces reservoir unit that stores coarsely crushed pieces made of a material that contains fibers;
a humidifying unit that generates humidified air and supplies the humidified air to the coarsely-crushed-pieces reservoir unit;
a weight measurement unit that measures a weight of the coarsely crushed pieces let out of the coarsely-crushed-pieces reservoir unit;
a fixed amount supplying unit that supplies a fixed amount of the coarsely crushed pieces measured by the weight measurement unit;
a defibrating unit that defibrates the coarsely crushed pieces supplied from the fixed amount supplying unit;
a first transportation portion through which the coarsely crushed pieces are sent from the coarsely-crushed-pieces reservoir unit to the weight measurement unit;
a second transportation portion through which the coarsely crushed pieces are sent from the fixed amount supplying unit to the defibrating unit; and
a humidified air supplying passage which includes an upstream-side end portion and a downstream-side end portion and through which humidified air generated at the humidifying unit is supplied to the defibrating unit while bypassing the weight measurement unit.
