ABSTRACT:
A bar code ruler is divided into a plurality of equally spaced increments each of which is marked by a machine readable bar code number. The ruler includes a plurality of recesses along the length thereof which cooperate with a spring biased ball carried by a slide member, the ball and recesses functioning as a detent to temporarily maintain the slide member in any desired position on the ruler. A hand held bar code reader is used to scan the bar code number on the ruler next to the slide with the edge of the slide functioning as a guide. A menu is also provided which includes a plurality of bar codes representing different component parts and sizes and a plurality of scale factors. The bar code reader can read the codes on the menu and on the ruler and feeds the information to a computer which counts the number of each size component part and which calculates the total length of pipes and similar components measured by the ruler.
