Abstract
PURPOSE: To simultaneously measure the racing times each with the use of a pair of start and stop switches by setting a preset program in a micro-processor.
CONSTITUTION: With a micro-processor 8, there are connected a clock pulse generating circuit 10 having a crystal oscillator 9, a mode interchanging switch 4, a start switch 5 and a stop switch, and further a display unit 3 through a digit display controlling output device 14 and a measured value display controlling output device 15. With the use of the measuring device thus constructed, the switch 4 is set for the auto-race mode, and the switches 5 are consecutively depressed at the starts of the respective cars. If the switch 7 is depressed when a preset distance is run, the course number and rap of each car are displayed in the display unit 3. By interchanging the switch 4, the measuring device can also be used as the events for the simultaneous starts.
