ABSTRACT:
A film holding reel includes a deformable hub on one portion thereof, and a compound lever hub deforming mechanism is used to deform that hub from a film supporting size and configuration to a film releasing size and configuration. The lever mechanism is adapted to move easily from a position in which the hub is undeformed, to an intermediate position, and then to require further manual actuation to move to a position in which the hub is in the film releasing size and configuration. A selected film portion can be changed using the film holding reel.
