Abstract
A system for supplying driving force to a recording and/or reproducing apparatus includes a first gear train which causes a supply or take-up reel table to rotate at a first speed, and a second gear train which causes the supply or take-up reel table to rotate at a second speed higher than the first speed. By selecting one of these gear trains, the apparatus selectively operates in a FF/REW mode or a high-speed FF/REW mode. In the FF/REW mode, the tape forwarding or rewinding is performed in a tape loaded condition in which tape is arranged in the usual tape traveling path. In the high-speed FF/REW mode, it is performed in a tape unloaded condition in which the tape is arranged at a location other than in the tape traveling path, or is housed within a tape cassette. The system has a torque limiter between a driving source and the first or second gear train. When the apparatus operates in a forward or reverse reproduction mode, the torque limiter acts on the first gear train so as to decrease the rotation speed of the supply or take-up reel table depending upon the load applied to the first gear train.
