GOLF SWING PRACTICE DEVICE

摘要

PROBLEM TO BE SOLVED: To make a golf club hold a function of transmitting information necessary for analyzing a hit ball only by sticking a sticker sheet on the head of the golf club.SOLUTION: A sticker sheet stuck on a club head includes: a converter formed by a piezoelectric film for detecting the impact position; an impact position detecting circuit formed by an IC tag for generating impact position information in response to an output signal from the converter; and an input/output circuit formed by an IC tag for outputting an output signal of the impact position detecting circuit by radio. An information processing part includes various kinds of electronic devices built in a golf practice mat stand disposed in the vicinity of a tee for setting a ball, and the information processing part receives radio information from the sticker sheet, analyzes the hit ball from the received information, and transmits the analyzed information by radio. An information receiving and reproducing processing part receives radio information from the information processing part, and displays it on a display or prints out it.
