Claims

[Scope of Claim for Utility Model Registration] A friction arm rotatably supported on a chassis, a large and small two-stage gear rotatably supported on the distal end side of the friction arm, and a friction arm rotatably supported on the chassis; A reel stand that is freely arranged opposite to each other and meshes with any of the two-stage gears mentioned above, a rotation transmission means that transmits rotation to the large and small gears that are pivotally supported at the tip of the friction arm, and a large and small gear that is rotated by the rotation of the friction arm. A cassette tape recorder comprising: a moving means for moving the two-stage gear to a position where it meshes with the reel stand; and an elevating means for bringing the large and small two-stage gears and the reel stand to the same level by raising and lowering a friction arm. drive switching device.
