ABSTRACT:
An apparatus including a camera body adapted to receive a thrust film cartridge, a thrust spindle for engagedly receiving a thrust cartridge spool, a take-up spool, and a mechanism for simultaneously driving both the thrust spindle and the take-up spool in an advance direction such that a surface speed of the take-up spool is faster than a surface speed of film being thrust from the thrust cartridge. A first one-way clutch is operatively positioned between a drive mechanism and the thrust spindle, and a second one-way clutch is operatively positioned between the drive mechanism and the take-up spool. A rewind spindle engagedly receives the thrust cartridge spool, and a rewind mechanism drives the rewind spindle in a rewind direction. A third clutch is operatively positioned between the rewind knob and the rewind spindle.
