ELECTRONIC MEASURE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an easily operated electronic measure apparatus of a simple structure which requires only a reel as a rotator for winding a cord on it. SOLUTION: An electric power source SW cum function SW 11 has both the function of turning on an electric power source of an internal circuit by a shallow downward push and half-locking the reel (not shown) on which the cord 13 is wound and the function of releasing the locking by a deep downward push to rewind the reel and house it in a main body case 2 and displaying the length of the cord 13 unwound to this point in time (i.e. the length of a section not to be measured of a material not to be measured) on a display part 12. A measurement reference line 14 is a marking line segment to be sequentially matched by an operator at measurement with both end parts of the section not to be measured of the material not to be measured.
