ABSTRACT:
A photographic camera (10) includes a supply chamber (14) for receiving a cartridge (16) enclosing a photographic filmstrip (18) wound on a supply spool (92); a rotatable member (90) disposed in the supply chamber for being coupled to rotate a supply spool of a cartridge installed in the supply chamber; a takeup chamber (20); a takeup spool (22) in the takeup chamber for winding a filmstrip drawn in a first direction from a cartridge in the supply chamber; a head (102) positioned between the supply and takeup chambers for at least one of reading and recording data on a filmstrip; a first drive system (24, 50-78) for rotating the takeup spool to draw a filmstrip from a cartridge in the first direction and wind a filmstrip onto the takeup spool; a second drive system (24, 50-68, 80-88) for rotating the rotatable member to rotate a supply spool to draw a filmstrip in a second, opposite direction from the takeup spool and wind a filmstrip onto a supply spool in a cartridge; and a brake mechanism (118, 118a, 118b, 118c), responsive to a change in rotation of the takeup spool from the first direction to the second direction, to resist rotation of the takeup spool in the second direction, so as to apply tension to a filmstrip to reduce variations in the speed of a filmstrip while the head records data as a filmstrip is wound from the takeup spool to a supply spool in a cartridge.
