Claims

[Claims for Utility Model Registration] A first gear meshing with a drive gear to which driving force is transmitted; a second gear provided integrally with the first gear; and the first and second gears. a first rotating arm that is rotatably supported by a first shaft; and a first rotating arm that is integrally provided with the first rotating arm.
an engagement pin provided opposite to the first rotating arm, supporting a third gear that meshes with the second gear, passing through the axes of the first and second gears, and extending through the axes of the first and second gears; a second rotating arm supported by a second shaft supported by the first rotating arm; and a second rotating arm integrally provided with the second rotating arm.
an engagement pin; a friction clutch that generates a frictional force between the third gear and the second rotating arm; and the first engagement pin and the second engagement pin are fitted into one of the engagement pins; The first engaging pin has an engaging pin regulating hole that regulates the swinging of the first engaging pin during recording and playback, and the second engaging pin during fast forwarding and rewinding.
and a mode switching member that restricts the swinging of the engagement pin, and when the first engagement pin is regulated by the mode switching member, the second rotation arm changes to the second rotation arm due to the frictional force of the friction clutch. rotates around the shaft and engages the third gear with the reel base gear;
When the second engagement pin is regulated by the mode switching member, the first rotating arm rotates around the first shaft due to the frictional force of the friction clutch, and moves the first gear to the reel. A reel drive mechanism configured to mesh with a speed increasing gear that meshes with a platform gear.
