Golf putting practice device

DETAILED DESCRIPTION What is claimed is: 1.
In a putting practice machine comprising a flat surface having a center line on which a golf ball may be placed and over which a golf club may be swung, one or more light sources, one or more sensors of said light, which upon said ball or head of said golf club interrupting the light to a respective sensor will generate a signal indicative of the position of said ball or said head, and means for detecting the signals; the improvement comprising a plurality of pairs of signal members positioned within said flat surface, each different ones of said pairs being disposed at different distances from said center line, and each signal member consisting essentially of one said light source and one said sensor, said one light source and said one sensor being positioned at angles with respect to one another so that a straight line extending from said light source will intersect a straight line extending from said sensor at a point about where said ball or said golf club head will pass.
2.
The machine of claim 1, wherein said flat surface is covered with artificial turf in areas outside of said signal members.




Description:
BACKGROUND OF THE INVENTION The present invention relates generally to improvements in a putting practice machine and more in particular to a novel construction of putter swinging indicating machine designed not only to help golf beginner judge right as to their own way of putter swinging motion but also to help skilled golfers repeatedly review their practical putting technique.
In any case when a putter is to be swung by a golfer in putting greens, it is generally pre-requisite for him to motion a putter in the direction of straight line while keeping a putter-head at an exact angle with respect to the supposed extension line along which a golf ball is to be rolled straight so that he is required for a higher swinging technique to always keep the exact position of a putter-head with respect to a golf ball thereby to move the same along a supposed straight line directing to a target hole
