ABSTRACT:
A single-use camera comprises a light-tight film casing and a film cassette located inside the casing. The film cassette includes a rotatable film spool with an end portion engageable to rotate the spool, and an active light lock with an end portion engageable to rotate the light lock open to permit film movement out of and into the cassette interior and closed to prevent ambient light from entering the cassette interior. The casing has separate weakened areas covering the end portion of the spool and the end portion of the light lock which can be entirely pierced to make respective perforations in the casing to permit individual access to the end portions to engage them for rotating the spool and for rotating the light lock closed and, simultaneously, to destroy the casing to prevent it from being reused.
