ABSTRACT:
A camera of the type employing a removable film cartridge including a plurality of individual film units, which are exposed and ejected one by one to complete their development outside the camera, has a base, a motor carried on the base, and an exposure housing and an access door each pivotable with respect to the base. A shutter mechanism, movable between a cocked condition in which exposure can be initiated and a run down condition in which exposure is terminated, is automatically recocked and the film ejected following exposure termination. The gearing for the film ejection mechanism and the shutter recock mechanism, as well as the pivot points of the access door and the exposure housing, are so disposed with respect to each other and to the output gear as to permit smooth engagement and disengagement of the gears during pivotal motion of both door and housing, or either of them. The motor is started by a motor start switch actuated when the shutter mechanism reaches its run down condition; a motor power switch, actuated when the motor starts, maintains power to the motor during the recock operation.
