Abstract
A lifting-lowering assembly for a stylus arm employs two flat portions having a pivot axis in the vicinity of the intersection of the two portions, a stylus arm rest on the first portion, and, an upwardly extending member on the second portion. The upwardly extending member cooperates with an electromagnetic device to rotate the assembly about the pivot axis. Air trapped under the first and second flat portions tends to permit gentle lifting and lowering operations by damping the rotational motion of the assembly.
