Abstract
To reduce the number of parts and simplify the structure by permitting the forward-rotation components and the reverse-rotation components to share a mechanism of transmitting the driving force to a pair of reel blocks 42F,42R. A pair of capstans 41F,41R respectively serving for forward rotation and reverse rotation and a pair of reel blocks 42F,42R respectively serving for forward rotation and reverse rotation are provided. One of the capstans, i. e. the capstan 41F, is provided with a low-speed gear 48, while the other capstan 41R is provided with a high-speed gear 49. The reel blocks 42F,42R are respectively provided with reel gears 50F,50R. A transmission changeover means 51 is installed to transmit the driving force from the low-speed gear 48 to the appropriate gear selected between the reel gears 50F,50R according to the direction in which the tape is run when the system is in either the forward mode or the reverse mode, and transmit the driving force from the high-speed gear 49 to the appropriate gear selected between the reel gears 50F,50R according to the direction of rotation of the tape when the system is in either the fast-forward mode or the rewinding mode.
