    摘要: An apparatus is provided for turning a rotor for each desirable angle by a capstan drive system wherein an eccentric free travelling ring carried by a turnable lever at a point removed from the pivot end of the lever is thus contactable and discontactable with a rotary shaft of the capstan drive system. A small gear is connected to the free travelling ring and is engaged with another large rotor gear for reducing the rotation thereof, the large gear being pivotally mounted on the pivot bearing of the turntable lever. Means are provided for biasing the free travelling ring toward the rotary shaft of the capstan drive system and further control means are provided for interlocking the free end of the turntable lever so as to prevent contact of the free travelling ring with the rotary shaft of the capstan drive system.

    摘要: A track change-over mechanism for shifting a magnetic head of a multi-channel tape recorder and comprising a cam follower for moving the magnetic head and bearing upon a stepped cam angularly displaceable with an idler wheel carried on a pivoted lever which rocks to a driving position in which the idler wheel is in driving contact with capstan means for rotating the idler and the stepped cam, an electromagnetic device for directly or indirectly actuating rocking of the pivoted lever and means including a second cam for disengaging the idler wheel drive when the stepped cam has shifted the stepped cam-follower, and thereby the magnetic head, by one step.
