Abstract

PROBLEM TO BE SOLVED: To facilitate the learning of a right swing by incorporating a light emitting diode and an acceleration sensor into the upper surface of a golf club and emitting light of the angle of a swing line as afterimages left in the eyes via a control circuit incorporated into a club shaft when golf club is swung. SOLUTION: A light emitting diode 2 is incorporated into the upper surface of a golf head, a control circuit 5, a battery 3 and a battery switch 4 are incorporated into a club shaft and they are connected so as to constitute an electric circuit by lead wire 7. When a golf club is swung, the light emitting diode 2 is flickered and a swing line is made to be left as afterimages in the eyes. At this time, a flickering period is adjusted so that an afterimage width when light is turned off may be narrower than the width of the light emitting diode 2 in the light emitting diode 2. Further, an acceleration sensor is incorporated into a club head, acceleration at the time of the swing is detected and the result may be constituted so as to perform an afterimage display for the result as figure, character and graphic patterns.
