<p>PURPOSE:To make a unit small-size by rotating the arm to the outside direction simultaneously with loading a magnetic tape onto the rotary drum incorporating a magnetic head to bring the magnetic tape into contact with the sound control head and the erasing head. CONSTITUTION:Rotary drum 4 incorporting a magnetic head, the first and the second arms 13 and 13' which have each one end supported rotatably by the first and the second rotary rings 9 rotated in directions opposite to each other, the first and the second tape guide axes 15 and 15' supported by both ends of the first and the second arms 13 and 13' respectively, and a means which is stopped by one of the first and the second guide axes 15 and 15' at least to move magnetic tape 5 and rotates the first and the second arms 13 and 13' to the outside direction before loading of magnetic tape 5 onto rotary drum 4 are provided, magnetic tape 5 is brougnt into contact with sound control head 27 and erasing head 28 under the state where the first and the second arms 13 and 13' are rotated to the outside direction.</p> |
