By means of high-speed kinematography taking about 900 photographs per second, anthers studied on the process of threshing a rice-ear with threshing cylinder. The summary of conclusion reached from this experiment follows: (1) the time required for threshing an ear is assumed to be about 1/100-2/100 second, (2) in threshing function there are two kinds; one is the action that the teeth directly strike against an ear while touching, and the other is the action that the grains are shaken off on the occasion of swinging ears, (3) ears are forced to be oscillated by advancing teeth and threshed materials are scattered fairly to side direction.
