DRIVE APPARATUS FOR TAPE RECORDER ABSTRACT OF THE DISCLOSURE In a drive apparatus for a tape recorder which has a pair of spaced apart selectively driven wheels, for example, of supply and take-up reel bases, respectively, a drive wheel located between the driven wheels and adapted- to be selectively rotated in forward and reverse directions by means of an electric motor for effecting rotation of an idler wheel which continuously engages the drive wheel, and a pivotally mounted support arm rotatably carrying the idler wheel and being swingable between a first position where the idler wheel bears against one of the driven wheels for. driving the latter from the drive wheel and a second position where the idler wheel bears against the other of the driven wheels for driving such other driven wheel from the drive wheel; a magnetic non-contacting coupling is provided between the idler wheel and the support arm so as to yieldably resist relative rotation thereof and thereby cause reliable swinging of the support arm to its first and second positions in response to rotation of the drive wheel in its forward and reverse directions, respectively. -1-
