A detecting mechanism in a film magazine spooling machine for detecting a missing end cap of a film magazine. The detecting mechanism comprises a pusher element movable a predetermined distance into engagement with one end of the magazine film spool and to apply pressure thereto. If the end cap is properly staked on the magazine, the film spool and pusher element is stopped thereby without interferring with the normal sequence of machine functions. However, if an end cap is missing from or improperly staked on the magazine, the pusher element is movable past the predetermined distance ejecting the film spool and improperly staked end cap from the magazine and causing a sensing mechanism responsive to movement of the pusher element to inhibit certain machine functions, and to actuate a diverting mechanism for diverting the defective magazine, and an annunciator to alert the operator.
