とするトーンアーム。By positioning the balance weight at the rear, the mechanical horizontal balance is placed in an unbalanced position where the stylus tip floats, and this is controlled by an electronically controlled electromagnetic drive device so that horizontal balance and appropriate stylus pressure can be obtained. The electronic control arm □ that lowers the balance weight is composed of a main weight 2 that fixes the balance weight in place and a sub-weight 1 that can be moved freely. The structure is such that horizontal balance is achieved on the one hand, and mechanical imbalance in which the needle tip floats is obtained on the other hand.
1. A tone arm characterized in that the sub-weight position detector is configured to electronically limit the operation of the electromagnetic drive device when the sub-weight 1 is on the side of mechanical horizontal balance.
