ABSTRACT:
A lighttight box includes a lid movable between a first lighttight position and a second box-opening position. A clamshell film-carrying mechanism, connected to the lid, is mounted for movement (1) for a retracted position internal to the box when the lid is in its lighttight position, to (2) an extracted film-delivery position external to the box when the lid is in its box-opening position. Actuator apparatus includes a lift mechanism, attachable to the lid when the box is in a parked film-delivery position relative to a workstation, movable between a rest position in which the lid is held in its closed position, and an actuated position in which the lid is held in its box-opening position. A motor, coupled to the lift mechanism, serves for driving the lift mechanism between its rest and actuated positions.
