Abstract

PURPOSE:To simplify the construction of a tone arm and to reduce the manufacturing cost, by providing a lead-in cam and a return cam which alternately depress a pressure-receiving pin horizontally left and right at one side of a plate. CONSTITUTION:A tone arm 2 is fitted on a cabinet 1 and a rester lever 4 is fixed to a tone arm shaft 3. The lever 4 is projected with a pressure-recepting pin 4a. A return cam 30 is fixed on the upper right side of a driving plate 27 extened in the direction of the lever 4, and a lead-in cam 31 is located by being clipped with the return cam 30 and the driving plate 27. The cams 30 and 31 alternately depress the pin 4a horizontally left and right to operate the tone arm. With the constitution like this, the construction of the tone arm is simplified and the manufacturing cost can be reduced.
