Abstract
Abstract In devices such as tape recorders, moving picture projectors and the like, the reels may be mounted on a single spindle having means for selectively engaging a selected reel for purposes of takeup or rewind. Specifically, the single spindle is provided with a single actuator which has latch means which may selectively engage a notch or slot of that reel which is to be driven, and thus to have that reel function as the takeup reel, or alternatively, as the rewind reel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
Apparatus for removably mounting and driving coaxial reels having hub opening with locking notches therein: a. a rotatable spindle; b. a reel support on the spindle for mounting reels in coaxial relationship; c. said spindle being apertured in zones corresponding to the hubs of the reels when mounted thereon; d. actuator means in the spindle with protrusion means for selective engagement with notches in the hubs of the reels; e. the actuator comprises a knob having depending fingers and depending actuator means having protrusions thereon; f. said fingers adapted for slidable movement in and out of said spindle; and g. said fingers acting as guides for said actuator means to prevent lateral movement thereof.
