Electronic tape measure

Abstract

Abstract PURPOSE: To improve the ease of use by adding a function of chaning and displaying measured values to the function of directly displaying measured values. CONSTITUTION: A mode select switch 11 is provided and is connected to a display device 9' by way of a processing unit 6', static memory 7', etc. Then, when the mode select switch 11 is set to the N position, the marks of the tape meansure 2 detected with a sensor 1' are counted in the processing unit 6'via waveform shaping circuit 3', and the counts are display in the display device 9'. When the mode select switch 11 is set to the P position, the static memory 7' becomes effective as a circuit element and the measured values are changed based on the memory contents of the static memory 7', after which the values are displayed in the display device 9' COPYRIGHT: (C)1979,JPO&Japio
