ABSTRACT:
A dual azimuth alignment mechanism of an autoreverse car audio device adjusts a head angle in contact with a tape by switching the screw installing portions inserted and connected with azimuth alignment screws by a changeover portion geared with a head movement portion. The head movement portion has a contacting portion for adjusting a head azimuth by making contact with the alignment screws. An azimuth alignment portion is pivotally installed at the head movement portion, and the screw installing portions formed at one side of the azimuth alignment portion selectively make contact with a contact portion. A thin plate is installed between the alignment screws and the contact portion for preventing abrasion of the contact portion. The azimuth alignment portion is fixed with a head at the head movement portion and is elastically switched by an elastic portion of the mounting portion.
