PURPOSE: To enable a trainee to easily check the locus depicted by a face surface, etc., by providing the light receiving means of a target practice machine having light emitting means and light receiving means within a putter of golf, etc., or a target with a prescribed length.
CONSTITUTION: The trainee installs the target 30, turns on a start switch 40 of the light receiving device 34 and sets the face 4 of the putter 1 toward the target mark 32 of the target 30. The trainee turns on a laser beam lighting switch 14 of the light emitting device 10 when the trainee thinks that the face surface 4 aligns to the target mark 32. A laser driving circuit 11 is then started and the visible laser beam is outputted from a sweet spot toward the target mark 32. The visible laser beam falls onto a phototransistor 35 and a buzzer 38 sounds when the face surface 4a faces the correct direction at this time. The trainee is, therefore, able to check whether the face 4 of the putter 1 is set at the correct plane of the target mark 32 or not.
