Abstract

The invention refers to an electronic length measuring device by which elongated articles as for example planks (5) can be easily measured and the total cost of which can be easily calculated. The invention substantially comprises a measuring tape which can be pulled out from the gauging station (1), and at the free end of which an operating device (3) is arranged. The measuring tape (2) is provided with a number of detectable elements (11) arranged along the measuring tape (2) at equal distances from each other. The detectable elements (11) are detected by a detector (8) arranged in the gauging station (1), the signals of which are supplied to an electronic unit. The operating device (3) is furthermore provided with at least one switch (15) by means of which the operator is able to initiate the electronic unit (14) to accumulate measured length values to a memory (22). This memory (22) would be updated each time the switch (15) is manually activated and the value accumulated in the memory (22) is shown on a sum display (20). The electric signals thus generated in the operating device (3) are transmitted by the transmission elements (12,13) which for example can consist of electric conductors to the gauging station (1) and the electronic unit (14), said electric conductors being arranged in the measuring tape (2).
