Claims

[Scope of utility model registration request]

a biasing means for biasing the head substrate to a non-performance position (or a performance position); an indexing means for indexing and locking the head substrate to a performance position (or a non-performance position) against the biasing means; When the indexing means that locks the head board during automatic music selection is unlocked, the head board, which is moved to a non-performance position (or performance position) by the energizing means, is locked in a position where the pressure contact between the pinch roller and the capstan is released. 1. A magnetic recording and reproducing device characterized by comprising an electromagnetic locking means for locking the device.
