Claims

[Scope of utility model registration request]

A base having reflective surfaces at several places, and several sets of light emitting elements and light receiving elements installed on the rising part on the back side of this base to form an optical axis with the reflective surfaces to detect the movement status of the golf club head. A golf practice machine that includes elements and a display unit that calculates the movement status based on signals from these elements and displays it.
