Abstract
A reel driving apparatus for use in a tape recorder such as a video cassette tape recorder, a digital audio tape recorder and the like, includes a rotary disk provided with an engaging protrusion and resiliently biased by a coil spring, an up/down bracket movable upward and downward together with the up/down bracket, and an idler gear engaging with upper and lower gears of supply and take-up clutches, selectively. By the arrangement described, the structure of deck mechanism becomes simple by using only a single idler mechanism to drive the supply reel and the take-up reel in different torques suitable for a high speed mode and low speed mode.
