Abstract:
Provided is a golf putting practice machine having a laser pointer, the golf putting practice machine includes: a laser direction adjustment plate (1) that that determines whether or not an emitted laser beam is directed in a normal direction; a laser pointer (2) that emits the laser beam toward the laser direction adjustment plate (1) when an ON/OFF switch (2-1) is in the ON state, wherein said switch is arranged to enable or prevent the emission of the laser beam; a laser pointer accommodating portion (3) that accommodates and fixes the laser pointer (2); a laser mount (4) on which the laser pointer accommodating portion (3) is mounted in an adhering manner; an aiming upper plate (5) on which the laser direction adjustment plate (1) and the laser mount (4) are placed so as to be slidable; an aiming plate (6) on which the aiming upper plate (5) is placed such that the ongoing direction of a golf ball is accurately set; a force-conversion roller (7) that converts the freefall of a golf ball into a horizontal force; a horizontal adjustment support plate (8) that fixes and supports the force-conversion roller (7) and performs leveling; an inclined height plate (9) that is connected to the force-conversion roller (7) so as to cause the golf ball to freefall; and a ball height adjustment plate (10) that is slidably connected to the inclined height plate (9) so as to determine the height from which the golf ball freefalls.
