Abstract

A motor-driven camera with stepping image-recordation control includes a shutter which extends between an objective and an exposure opening of the camera, and a friction segment member which engages the film accommodated in a camera to advance the same in predetermined increments from a payout core to a takeup core in a path leading past the exposure opening. The shutter and the friction segment member are mounted on respective shafts which are normal to one another and also to the output shaft of the electric motor which drives the camera. The output shaft has a worm provided thereon, and the shafts of the shutter and of the friction segment member have worm wheels which mesh with the worm. A friction roller engages the film opposite to the friction segment member, and a friction transmission incorporating a friction clutch or coupling is interposed between the friction roller and the capstan for the takeup core to rotate the latter as the film advances. The friction coupling may include a pressure plate component, a housing component adjacent thereto, and a spring accommodated in the interior of the housing component and so engaging the components as to permit slippage therebetween. The friction transmission may include a belt which is trained about the housing component and is received in a circumferential groove provided in the periphery of the housing component.
