Abstract
In a magnetic tape recording/reproducing apparatus, an idler moves an idler gear selectively between a supply reel and a take up reel to transfer power respectively to the reels. During loading of the tape of a cassette tape, an upper chassis, with the tape cassette and drum, is seated on a lower chassis, with the loading and travelling gearing apparatus. During seating operation, the idler is held in a central position by an idler cam having a cam surface to be out of the way of the components on the upper chassis, thereby eliminating interference with the seating operation. During normal tape running operations, the cam surface controls the movement of the idler.
