Contact state observation apparatus of golf ball and contact state observation method of golf ball

Abstract

A contact state observation apparatus of golf ball can observe the contact phenomenon between a golf ball and a golf club which has been conventionally hidden and unobservable. The contact state observation apparatus of golf ball includes: launching means for launching a golf ball 10; an impact plate 20 with which the launched golf ball 10 impacts; and imaging means 30, provided opposite to the launching means across the impact plate 20, for shooting an image of the contact state between the golf ball 10 and the impact plate 20 at the time of impact of the golf ball 10. The impact plate 20 has, in a part where the golf ball 10 impacts, an observation hole 21 whose area is smaller than a contact area with the golf ball, and the imaging means 30 shoots the image of the contact state through the observation hole 21.
