Golf swing training apparatus
First Claim
1. In a golf practice apparatus which includes structure defining a normal path direction and a normal point of impact of a golf club head during a practice swing, mechanism for representing the face angle of the swinging club head, comprising in combination,a pair of light-receiving sensors aligned laterally of the club head path and positioned for respectively developing signals proportional to the portions thereof which are overshadowed by a swinging club head at a triggered sensing time,and output means for utilizing the signals from said sensors as a representation of the face angle of a club head at said sensing time.

Abstract
A golf practice apparatus wherein a pair of light-receiving sensors are aligned laterally of the club head path and are positioned for respectively developing signals proportional to the portions thereof which are overshadowed by a swinging golf club head at a given sensing time which is also triggered by the golf club head overshadowing a third trigger sensor. The two aligned sensors are light-receiving windows and the amount of light received from each of these windows is received by respective light sensors. The light from these sensor windows is preferably focused to respective light-diffusing surfaces from which respective light sensors read the amount of light received. The signals from these respective sensors are compared to thereby produce a resultant signal representative of the face angle of the club head which may be indicated on a meter.
