Claims

[Scope of utility model registration request]

In a record player in which a linear tracking arm equipped with a playback stylus is provided on a conveying body that is linearly moved along a guide member, an elastic electrode is provided on the side of the conveying body, and a fixed surface facing the elastic electrode is provided with an elastic electrode. In a record player having a structure in which a plurality of fixed electrodes are arranged at predetermined locations, and the elastic electrodes come into elastic contact with the fixed electrodes as the carrier moves, thereby detecting a predetermined position of the playback stylus with respect to the record surface. Regenerated needle position detection device.
