Claims

[Scope of utility model registration request]

A head base equipped with a magnetic head is slidably provided on the chassis, and this head base is biased in a direction in which the magnetic head is separated from the tape, and a switching head that is in contact with this head base is provided. In a switching device for a tape player, the switching cam is provided with a switching gear that rotates together with the switching cam, and a drive gear that applies rotational force to the switching gear. A pressing portion for pressing the head base in the direction in which the magnetic head moves away from the tape and a step portion for returning the head base in the direction in which the magnetic head separates from the tape are formed adjacent to each other. A tooth-missing portion is formed that continues to face the drive gear from the rotational position where the step portion contacts the head base to the rotational position where the step portion contacts the head base, and the suppressing portion contacts the head base ( , a locking member that stops the switching gear when it is in this locked state, and a locking member that urges the switching gear to rotate when it is in this locked state.
A switching device for a tape player, characterized in that a =j force member is provided.
