Abstract
A spring loaded reel is provided for accommodating and storing an extensible tape member which is useful in identifying the length of an object to be measured while being pulled out of an electronic combined digital scale and calculator. A plurality of holes are provided in the body of the spring loaded reel to detect the movement of the extensible tape member. A photo detector is positioned associated with the spring loaded reel to sense the rotation of the spring loaded reel in unison with the extensible tape member and to thereby provide counting signals. The counting signals are manipulated in a processor circuit included within the electronic digital scale and calculator to identify the movement of the extensible tape member.
