1. A fiber manufacturing apparatus, comprising:
a discharge head configured to discharge a raw material liquid in which a polymer is dissolved in a solvent in a discharging direction toward a collector at a spinning position of the discharge head;
a power source configured to generate a potential difference between the discharge head and the collector;
a recovery belt, provided adjacent to the collector and at the same plane as the collector, configured to receive the raw material liquid to be discharged by the discharge head toward the recovery belt at a recovery position of the discharge head; and
an actuator configured to move the discharge head between the spinning position where the discharge head is configured to discharge the raw material liquid toward the collector and the recovery position where the discharge head is configured to discharge the raw material liquid toward the recovery belt, wherein
the recovery belt and a tip of the discharge head are spaced in the discharging direction, and, at the spinning position, the discharge head is positioned between a collector at each side of the discharge head, and at the recovery position, the discharge head is positioned between a recovery belt at each side of the discharge head and between two cleaning members at each side of the discharge head.
