Abstract

PURPOSE: To prevent a wow of a tape between a supply-side reel and capstan by providing a back tension generator to the reel mechanism of a tape recorder that provides reverse play by use of a unidirectional clutch.
CONSTITUTION: Since unidirectional clutch 64 is turned by the rotating force of electric motor 37 at the 1st reel mechanism 12 when tape 90 is forwarded from the 2nd reel mechanism 14 to the 1st reel mechanism 12, the 1st projection 92 of rotation inhibiting means 96 is oscillated counterclockwise through the movement of teeth 70 as ratchet 66 rotates and never engages with ratchet 66. Ratchet 166 of the 2nd reel mechanism 14 is engaged with the 2nd projection 94 to inhibit ratchet 166 from rotating. Therefore, frictional force between connecting method 162 and unidirectional clutch part 164 provides tape 90 with back tension. Thus, a wow of the tape can be prevented.
