Title: Digital tape measure
Inventor: NAKAJIMA TADAO
IPC: G01D5/245
Filed: 1983-10-14
Abstract: PURPOSE:To display surely length without errors by magnetizing a magnetic material layer provided on one surface of a long-sized body for measuring length to different states, detecting the magnetized states with a detecting part into which a Hall element is incorporated, calculating the detected states and converting the same to length. CONSTITUTION:The layer of a magnetic material provided as a surface extending over roughly the entire part in the longitudinal direction of a long-sized body B is magnetized. For example, the magnetic material layer is segmented by each unit length (x) along the longitudinal direction (z) of the long-sized body from a reference line (y) and the inside of the first region is magnetized to the state N-S. The inside of the 2nd region is then magnetized to the state S-N. The magnetic material layer is thus alternately magnetized to different states by each of the unit length (x) to constitute a row 1. The row 2 is segmented by each unit length 2x along the longitudinal direction of the long-sized body from the line (y). The inside of the first region is magnetized to the state N-S and the inside of the next region is magnetized to the state S-N to constitute said row. The row 3 is similarly magnetized by making the unit length 4x. The digital tape measure is thus constituted by magnetizing generally the rows (n) to the alternately different states with 2<(n-1)>x as the unit length.
