The present invention relates to a golf putting training apparatus
comprising a reaction panel (2); a personal computer that computes
detected data; a body having a display portion (3) that displays the
output data; two triangular detection areas (A, B) that symmetrically
crisscross each other in a plane space between the two side panels (4,
4') of the body (1); light emitting elements (L, R) of detection sensors
(S1, S2) installed at the vertex positions of said triangular detection
areas (A, B) on side panels (4, 4'); light receiving elements (L1, L2,
R1, R2) of detection sensors (S1, S1) provided at the corner positions of
the bottom lines of said triangular detection areas (A, B) in such a way
as to face said light emitting elements (L, R).
