摘要： A roll film cassette has a film storage chamber and a film take-up chamber; these are connected by a web along which the film moves as it travels from the storage chamber to the take-up chamber. The web is provided adjacent the inlet to the take-up chamber with a springy detent a projection of which rides on the film and snaps into a perforation formed adjacent the film end in the film and/or in an end paper of the same. This prevents the film end from slipping into the take-up chamber and becoming inaccessible.

摘要： A motion-picture film cassette has a pay-out spool and a take-up spool mounted coaxially, but at opposite sides of a divider wall. Film travels in one direction through the wall from the pay-out spool to the take-up spool. An anti-reversing device is provided to prevent reverse movement of the film and/or spools; it includes an annulus of holes in the wall, surrounding the axis of the spools, and a resiliently yieldable finger projecting from that surface of the take-up spool which faces the wall. The finger ratchets over the holes when the take-up spool turns in take-up direction but engages in a respective one of the holes to block reverse movement when the take-up spool attempts to turn in the opposite direction.
