Abstract

PURPOSE:To attain thin profile for the entire device by meshing with a gear having a unidirectional clutch to at least one gear of a couple of reel bases. CONSTITUTION:A gear 18 having a unidirectional clutch 17 meshes with a gear 12 provided at least one of reel bases 2, 3. In the FWD system mode such as recording or reproduction of a tape, the gear 18 having the unidirectional clutch 17 is driven nearly at no load together with the gear 12 of the reel base 2. In the RVS mode at tape rewinding or the like, the gear 18 is stopped by the clutch 17 and a load is applied to the gear 12 of the reel base 2 to suppress idle rotation of the reel base. Thus, the thickness required for a brake drum is not required, then the device profile is made thin by the thickness.
