Claims

[Claims for Utility Model Registration] A drive gear to which rotational driving force of a motor is transmitted;
a recording/reproducing gear to which rotational driving force is transmitted via the driving gear; a fast forwarding/rewinding gear to which rotational driving force is transmitted via the driving gear; and a gear for supporting the recording/reproducing gear. , a first swinging member that is swingably provided so that the recording/reproduction gear meshes with the gear of the supply reel stand or the take-up reel stand; , a second swinging member supporting the fast-forwarding/rewinding gear and swingably provided so that the fast-forwarding/rewinding gear meshes with the gear of the supply reel stand or the take-up reel stand; A reel drive mechanism comprising: a switching member that selectively abuts the first or second swinging member depending on a mode to switch a driving force transmission path to the supply reel stand or the take-up reel stand.
