A one-time-use flash camera comprising a camera housing that contains a cartridge chamber holding a film cartridge and a film roll chamber holding an unexposed film roll on which a predetermined maximum number of exposures can be made, and a flash device, is characterized in that the flash device has a total number of flash lamps that is equal to the predetermined maximum number of exposures that can be made on the unexposed film roll, and is connected non-removably to the camera housing in order that the flash device must be broken off the camera housing to separate the flash device from the camera housing, whereby once each one of the flash lamps is used there will not be any exposures that can be made and the one-time-use flash camera must be discarded.

One-time use camera with multi-lamp flash

A camera is provided with a front flip-up flash unit and a rear flip-up flash retainer having front and rear viewfinder openings that are aligned to view a subject to be photographed when the flash unit and the flash retainer are flipped up. If the flash unit is folded down for storage, the flash retainer is folded over the flash unit to secure the flash unit in place.

Camera with front flip-up flash unit and rear flip-up flash retainer

A camera comprises manually rotatable film winding means, and a uni-directional clutch coupled to the film winding means to permit film winding rotation of the film winding means and to prevent reverse rotation of the film winding means. The film winding means includes a rotatable winder wheel having a toothed periphery. The uni-directional clutch includes a rotatable idler wheel having a toothed periphery engaging the toothed periphery of the winding wheel and provided with less teeth than the toothed periphery of the winding wheel, and a coil spring coiled tightly about a shank of the idler wheel and having an end portion secured with respect to the shank. The coil spring tightens on the shank to prevent the idler wheel and the winding wheel from being engagingly rotated when reverse rotation of the film winding means is attempted and relaxes on the shank to permit the idler wheel and the winding wheel to be engagingly rotated when film winding rotation of the film winding means is initiated.
