<p>Film unwinding apparatus (121) is to be used with a film spool having a hook that extends substantially in a film winding direction of rotation of the spool and through a hole in a trailing end portion of a filmstrip to engage the trailing end portion to prevent it from being pulled off the spool. The unwinding apparatus (121) is adapted to pull the filmstrip off the film spool in a way that makes the spool rotate with the filmstrip in a film unwinding direction. A weighted body (145) is connected to the film spool to be rotated by the spool in the film unwinding direction as the filmstrip is pulled off the spool. This allows the weighted body (145) to provide a momentum to rotate the film spool relative to the trailing end portion in the film unwinding direction when the filmstrip except for the trailing end portion has been pulled off the spool, to back the hook out of the hole to allow the trailing end portion to be pulled off the spool without ripping the filmstrip. <IMAGE></p> |
