Abstract
A number drawing apparatus includes a rotating unit and collecting holes. Each ball, supplied from a supply unit provided in the central portion of the rotating unit when it rotates, randomly rolls on a surface of the rotating unit. A centrifugal force by the rotation causes each ball to move outwardly from the rotating unit, and each ball is caught in one of catching holes. Unique identifying symbols are assigned to the catching holes. This enables the draw.
