Abstract
A moving body measuring instrument is disclosed which projects, from predetermined locations thereof, a plurality of beams of light at predetermined angles into a same plane, receives, at predetermined locations thereof, the beams reflected from a moving body as it moves to intersect with the beams, calculates parameters of the motion of the moving body in accordance with predetermined operation from timing data of the beams received, and indicates the results of the calculations on an indicator. The moving body has a light reflective member provided thereon which reflects a beam for measurement toward a direction incident thereto irrespective of its incident angle, and substantially same locations are provided at which beams are projected and received.
