Abstract

See full text

To provide a device for measuring a time of passage that is capable of sensing passage of the torso more accurately than a photoelectric cell while maintaining the ease of use of a photoelectric cell, passage of a runner is sensed by causing the upper portion of the body of the runner to be broadly illuminated by infrared light, visible light, and/or other such electromagnetic waves, and by detecting light reflected from large part(s) of the body of the runner.
