    Abstract: A tape transport apparatus in which the take-up and take-off reels are simultaneously driven by surface engagement of a capstan with the outermost tape layer on each reel. The reels are rotatably mounted on carriages which are translationally slidable with a minimum of friction and are urged towards each other by springs to provide substantially equal compressive forces at the two zones of tape engagement. The capstan has little or no resilient material on its peripheral surface to permit tape slippage under the action of a brake which, due to the provision of a unidirectional clutch, is effective only on the supply side of the apparatus. The brake is designed so that the braking torque changes substantially in direct proportion to the distance of the axis of the supply carriage from the capstan periphery. In this fashion the tape tension in the span between the above two zones of tape engagement is maintained virtually constant.

    Abstract: A cassette loading mechanism for use in conjunction with a tape transport apparatus in which the take-up and supply reels are simultaneously driven by surface engagement of a capstan with the outermost tape layer on each reel. The loading mechanism enables a hinged protective cassette containing a supply reel to be easily loaded into the tape transport apparatus and made ready for threading with only three simple actions to be performed by the operator. First, depending on the particular embodiment, the cassette is loaded into either a cassette tray or into a pocket in a hinged door directly over the take-off shaft. Second, pushing down, either on the cassette itself or on the hinged door, accomplishes the simultaneous snapping of the hub within the cassette onto the supply shaft and the releasing of the locks holding the cassette closed. Finally, the sliding of a single knob opens the cassette and advances the supply tape pack until brought into contact with the driving capstan. Removal of the cassette with the tape therein after use is accomplished by the reversal of the above operations.
