Abstract
A tape reel driving device for generating torques for high and low speed tape travel, has first reel gears respectively combined with the reel driving tables so that each of the first reel gears and a corresponding one of the reel driving tables rotate together, and second reel gears respectively combined with the reel driving tables so that each of the second reel gears rotates by a predetermined frictional force together with a corresponding one of the reel driving tables, each of the second reel gears being capable of racing. A first idler is movably supported to be selectively connected to either one of the first reel gears of the pair of reel driving tables, and a second idler is movably supported to be selectively connected to either one of the second reel gears of the pair of reel driving tables. A movement preventing device for allowing the movement of one of the first and second idlers while preventing the other from moving, a motor for generating power, and a driving gear member which is rotated by the motor and which selectively drives the first and second reel gears through one of the first and second idlers are also provided.
