The drive force transmitting means for driving the reproducing magnetic medium is separate from that for driving the recording magnetic medium. Each drive force transmitting means is provided with a pin that engages a single cam member, the rotation of said cam member causes each lever to move, thereby achieving reproduction/rewinding of said reproducing magnetic medium and recording/rewinding of said recording magnetic medium alternately. ## Claims ### Claim 1 Recording-reproducing apparatus for the automatic answering of telephones comprising: first and second independently movable, elongated, flexible recording media, one for storing a pre-recorded message to be transmitted and the other for recording an incoming message, first supply and take-up means for the first of said media for effecting forward and rewind movements thereof, second supply and take-up means for the second of said media for effecting forward and rewind movements thereof, motive means, cam means driven by said motive means, first pivotable lever means formed with first follower means for following said cam means and with first pulley means driven by said motive means, second pivotable lever means formed with second follower means for following said cam means and with second pulley means driven by said motive means, said first lever means being pivoted in response to the movements of said first follower means in such a manner as selectively to bring said first pulley means into driving relation with at least said first take-up means and thereby control at least the forward movement of the first of said recording media, and said second lever means being pivoted in response to the movements of said second follower means in such a manner as selectively to bring said second pulley means into driving relation with at least said second take-up means and thereby control at least the forward movement of the second of said recording media. ### Claim 2 (depends on 1) Apparatus according to claim 1, wherein said first lever means is pivoted in response to the movements of said first follower means in such a manner as selectively to bring said first pulley means into driving relation with said first supply means and thereby control the rewind movement of the first of said recording media, and said second lever means is pivoted in response to the movements of said second follower means in such a manner as selectively to bring said second pulley means into driving relation with said second supply means and thereby control the rewind movement of the second of said recording media. ### Claim 3 (depends on 1) Apparatus according to claim 1, further comprising biasing means for automatically controlling the rewind movement of at least the first of said recording media upon termination of said driving relation of said first pulley means to said first take-up means. ### Claim 4 (depends on 1) Apparatus according to claim 1 wherein said first and second recording media are respectively first and second magnetic tapes. ### Claim 5 (depends on 1) Apparatus according to claim 1 wherein said first supply and take-up means comprises a first feed reel and a first take-up reel and said second supply and take-up means comprises a second feed reel and a second take-up reel. ### Claim 6 (depends on 1) Apparatus according to claim 1 wherein said first supply and take-up means comprises biasing means connected to the first of said recording media for controlling the rewind movement thereof and a first take-up reel and said second supply and take-up means comprises a second feed reel and a second take-up reel. ### Claim 7 (depends on 1) Apparatus according to claim 1 wherein said cam means comprises a cam wheel having a first cam face of a given configuration and a second cam face of a different configuration and wherein both of said follower means engage said cam faces, the arrangement being such that when one of said follower means engages one of said cam faces, the other of said follower means engages the other of said cam faces. ### Claim 8 (depends on 1) Apparatus according to claim 1 further comprising time indicating means mounted coaxially with said cam means and rotating therewith. ### Claim 9 (depends on 8) Apparatus according to claim 8 wherein said time indicating means comprises a disc with visible indicia thereon.
