ABSTRACT:
A timing system for swimming race which records, displays, and prints the time of race. To provide a mask circuit in a control device which controls each signal, enables the timing system to exactly perceive a swimmer's touch. Furthermore, a top edge panel is provided on a touch panel so as to perceive a swimmer's touch at an oblique angle. A plurality of lane boxes are provided for backup of a touch signal and a starting block signal, in case of failure and misoperation of the control device. Further, a visual display device is provided in order that a swimmer can recognize a starting signal visually.
