Abstract

PURPOSE: To expand range of measurement and improve measuring precision by operating through the prescribed formula the average velocity and the elapsed times at the front or rear end of a mobile body measured by three detectors or more arranged at given intervals.
CONSTITUTION: If three detectors or more, such as photosensors, are arranged at distances li in the moving direction of a mobile body 14 and the time Tjk necessary for the front or the rear end of the mobile body 14 to move from the jth to the kth sensor are detected through a counter, etc., the average velocity at the front or the rear end of the body 14, STi or SBi is determined by the division of the distance li. One of the formulas IWIV is selected where calculation precision can be improved in accordance with the arrangement of the length detectors 1, 2... of the body 14 and on the basis of it is calculated the length LMjk of the body 14. Moreover, the average of the length, LMjk or the LMjk corresponding to the minimum among STi. Tik, SBi.Tik is selected as the measured length. In this way the length of a mobile body can be measured widely and precisely in response to the arrangement of detectors.
