A camera is provided with a loading chamber insertion mechanism for receiving a film cartridge of the type having a retention slot formed therein inserted manually into an insertion position by positively engaging the retention slot, pulling the cartridge into the chamber, and seating the cartridge in a seated position. A movable clamp and escapement mechanism are operable in an initial, insertion position for latching a carriage against movement in response to a biasing force provided by a tensioning spring. The movable clamp is pivotally mounted to the clamp for movement within escapement channels that cooperatively latch the carriage in the insertion position. The clamp pivots on the carriage within the escapement channels on being contacted by the film cartridge during its initial end- wise insertion by the user. The clamp pivots in the escapement channels to an intermediate, unlatched position that releases the carriage for movement in response to the biasing force and simultaneously engages the film cartridge retention slot. The carriage and clamp are pulled by the spring biasing force through the escapement channels and in turn pull on the engaged film cartridge to effect seating of the film cartridge in the loading chamber.
