Claims

[Scope of utility model registration request]

An auto-reverse tape recorder that automatically or forcibly switches the tape running direction from the forward side to the reverse side for continuous playback and also allows recording only on the forward side, is equipped with a magnetic head that moves the capstan shaft during recording or playback. A headshaft that moves forward to the side; a plate lock that once moves in the release direction due to the forward movement of the headshaft and then engages with the headshasis to prevent it from retreating; a plate slide that moves in the same direction; a lever lever that moves together with the head chassis to operate the recording switch only when recording is possible; An automatic recording mode release mechanism for an auto-reverse tape recorder, comprising a retrieval operation for operating the plate lock rotated by a plate slide in the release direction.
