Title:
BALL SENSING DEVICE OF GOLF TRAINER
Document Type and Number:
WIPO Patent Application WO/2013/105726
Kind Code:
A1
Abstract:
The present invention relates to the ball sensing device of a golf trainer, and more particularly, to the ball sensing device of a golf trainer in which noise is blocked and detection by a light receiving sensor is improved. The ball sensing apparatus of a golf trainer according to the present invention includes a plurality of sensing units, a frame, and an infrared filter. The sensing unit includes: a light-emitting sensor; a light-receiving sensor; a light-emitting sensor accommodation unit accommodating the light-emitting sensor to guide light emitted from the light-emitting sensor to the outside; and a sensor case including a light-receiving sensor accommodation unit which is disposed parallel to and spaced a predetermined distance from the light-emitting sensor accommodation unit to accommodate the light-receiving sensor, thereby guiding the light of the light-emitting sensor reflected from the golf ball to the light receiving sensor. The frame arranges the sensing units in a line. The infrared filter is disposed above the sensor case. As such, the sensor case may be stepped so that the inlet of the light-receiving sensor accommodation unit is narrow in order to improve the collimation of the light received into the light-receiving sensor accommodation unit. According to the present invention, since the light-receiving sensor is mounted on the light-receiving sensor accommodation unit, which is stepped so that the inlet thereof is narrow, light collimation may be improved, and thus the accuracy of the light-receiving sensor may be improved.
