Claims

[Scope of utility model registration request]

(1) A light-emitting means that projects light through a light-emitting lens to form a plurality of bundles of light rays separated by a predetermined distance, and receives reflected light from a baseball bat that crosses each of the bundles of light rays through a light-receiving lens. A swing measuring device comprising: a plurality of optical transceivers each having a pair of light receiving means; and a control calculation means for processing an output signal from the light receiving means and outputting data regarding the swing of the baseball bat. The light-emitting lens and the light-receiving lens are arranged close to each other on the upper surface of each of the optical transmitters and receivers, and have a predetermined inclination angle from a base point on a horizontal plane set close to the light-receiving lens so as to at least cover both lenses. A light-transmitting slope cover is provided, and when a beam of light projected upward through the light-emitting lens passes through the slope cover, the resulting reflected optical path is directed to a side opposite to the light-receiving lens with respect to the light-emitting lens. A swing measuring device characterized in that it is configured to be formed in a direction.

(2) The swing measuring device according to claim 1, wherein the slope and the cover have an inclination angle of 20 degrees to 30 degrees.

(3) The swing measuring device according to claim 1 or 2, characterized in that the slope cover is fitted with a glass material.

(4) The swing measuring device according to claim 1 or 2, wherein the slope cover is a filter that allows only infrared rays of a predetermined wavelength including 800 μm to pass through.
