Putting exerciser for evaluating hitting speed and tempo of putter

A putting exerciser for evaluating a hitting speed and a tempo of a putter, the exerciser comprising:

• sensor installation units provided to be spaced apart from and face each other in a direction parallel to a traveling direction of a golf ball (1);
• a radiation unit (100) for radiating light or a light receiving unit (200) in a first sensor installation unit;
• a light receiving unit (200) or a radiation unit (100) in a second sensor installation unit;
• a speed detection unit (300) for detecting a speed of the golf ball (1) by checking a moment the golf ball passes when the golf ball (1) is putted as the light radiated from the radiation unit (100) is received by the light receiving unit (200);
• a position measurement unit (400) for measuring a position of the golf ball (1);
• an operation control unit (500) for performing calculation to detect an initial position value of the golf ball (1) measured by the position measurement unit (400) and a moving speed Vb and a moving distance Hb of the golf ball (1) measured through the speed detection unit (300);
• and
• a storage unit (600) for storing the measured speed Vb and distance Hb of the golf ball (1),
• wherein the radiation unit (100) includes:
• a first radiation unit (110) for radiating light to detect the initial position of the golf ball (1);
• a second radiation unit (120) for radiating light to detect the speed of the golf ball (1);
• and
• a third radiation unit (130) for radiating light to detect the hitting speed and tempo of the putter (2) moving behind the golf ball (1) to hit the golf ball (1),
• wherein the light receiving unit (200) includes:
• a first light receiving unit (210) installed to face the first radiation unit (110) to receive the light radiated from the first radiation unit (110);
• a second light receiving unit (220) installed to face the second radiation unit (120) to receive the light radiated from the second radiation unit (120);
• and
• a third light receiving unit (230) installed to face the third radiation unit (130) to receive the light radiated from the third radiation unit (130),
• wherein the third radiation unit (130) includes:
• a 31st radiation unit (131) installed to be close to the first radiation unit (110);
• and
• a 32nd radiation unit (132) installed at a location spaced apart from the 31st radiation unit (131) by a predetermined distance Dc,
• wherein the third light receiving (unit 230) includes:
• a 31st light receiving unit (231) installed to correspond to the 31st radiation unit (131);
• and
• a 32th light receiving unit (232) installed to correspond to the 32nd radiation unit (132),
• wherein when the time detected through the 31st radiation unit 131 and the 31st light receiving unit (231) after the putter (2) starts backswing is t0, and the time detected again through the 31st radiation unit (131) and the 31st light receiving unit (231) after the putter (2) is switched from backswing to downswing and moves forward is t1, the tempo T is defined as T=t1−t0,
• wherein when the time detected through the 32nd radiation unit (132) and the 32nd light receiving unit (232) after the putter (2) is switched to downswing and moves forward is t2, and the distance between the 31st radiation unit (131) and the 32nd radiation unit (132) is Dc, the speed Vp of the putter (2) is defined as Vp=Dc/(t1−t2).
