Tone arm assembly in record player

A tone arm assembly installed on a face plate of a record player housing, is constructed such that said tone arm assembly is easily divided into two sections, one a tone arm structure for supporting the tone arm and allowing it to horizontally and vertically oscillate and the other a supporting structure for holding said tone arm structure over the face plate. The two sections can be aligned and coupled to each other by a single manual motion for operation of the record player. The coupling sections of many tone arm structures each having a different tone arm are formed in the same form so that any of the tone arm structures can be selectively aligned and coupled to one another and the same supporting structure. A lead-out portion for pick-up lead wires therethrough to the outside is provided at one side of said supporting structure.
