A single-use camera (10) comprises a film cartridge (14) including a cartridge shell and a film spool (30) rotatably supported inside the shell with a cylindrical drive hub end (32) axially protruding from the shell, and a manually rotatable film advance thumbwheel (16) with an axially depending drive spindle engaging the drive hub (32) end to rotate the spool (30). The cylindrical drive hub end (32) has a pair of adjoining semi-cylindrical wall portions (34,36), one of which (34) protrudes farther from the shell than the other (36). The drive spindle has a single semi-cylindrical wall portion matingly shaped to engage the cylindrical drive hub end at its pair of adjoining semi-cylindrical wall portions. <IMAGE> |
