A take-up assembly for operating a mechanism for loading and unloading the leader block of a tape cartridge, and for receiving the web of tape which it contains for subsequent transport, stores energy for transfer to the leader block loading/unloading mechanism when it is to operate to load or unload the leader block, so that even a conventional take-up motor is made capable of supplying the increased energy needed for leader block loading/unloading. A preferred take-up assembly includes a hub which is directly coupled to the take-up motor and which serves to receive the web of tape for direct transport, and a coupling which is nested within the hub and which receives the leader block loading/unloading mechanism. A pin depends from the coupling and into a circumferentially arranged slot formed inthe hub, to connect the hub and coupling as the pin engages the ends of the slot.
