A camera comprising a taking lens, a lens support for supporting the taking lens, and a transparent lens cover for shielding the taking lens, is characterized in that the transparent lens cover has a plurality of retaining portions that constitute a single piece with the transparent lens cover and are individually connected to the lens support to hold the taking lens to the lens support, but which can be individually disconnected from the lens support to free the taking lens.

One-time-use camera with transparent lens retainer-cover

A one-time-use camera comprising a taking lens for making successive exposures on a filmstrip, is characterized in that a lens disfiguring member is movable over the taking lens to scratch the taking lens after the last exposure has been made on the filmstrip, to prevent the taking lens from being reused.

One-time-use camera with lens disfiguring mechanism

A one-time-use camera comprising a main body part having a chamber, and a film cartridge adapted to be located in a predetermined position within the chamber, is characterized in that the film cartridge is a modified cartridge as compared to a standard cartridge, because it has a recess that is not on the standard cartridge, and the main body part has a blocking protuberance that projects into the chamber to fit in the recess when the modified cartridge is located in the predetermined position within the chamber, but which will abut the standard cartridge to prevent it from being located in the predetermined position within the chamber if one attempts to substitute the standard cartridge for the modified cartridge, and which has a hollowed-out space that will allow ambient light to leak into the chamber should one cut the protuberance off the main body part at the hollowed-out space in order to permit the standard cartridge to be located in the predetermined position within the chamber.

One-time-use camera can only be used with modified film cartridge, to

A method of remanufacturing a one-time-use camera having the following steps. Cutting a protuberance off a main body part of the camera at a hollowed-out space in the protuberance in order to permit a standard cartridge to replace a modified cartridge within a chamber in the main body part. Closing a hole in the chamber, resulting from the protuberance being cut off the main body part at the hollowed-out space, to prevent ambient light from leaking into the chamber through the hole. And properly positioning the standard cartridge in the chamber.

Method of remanufacturing one-time-use camera

A single use camera having an electronic flash assembly including a flash charging circuit and a flash illumination circuit is provided with one or more access openings in the camera cover. The access openings are aligned with contact terminals in the flash charging circuit to allow insertion of a shorting device that acts to disable operation of the flash charging circuit. This is useful during a film loading operation to prevent charging of the flash capacitor which might otherwise be caused by electrostatic start up of the flash charging circuit. Preventing operation of the flash charging circuit in preference to shorting of the flash capacitor directly preserves battery power and assures the flash charging transistors will not be damaged by attempting to charge into a short circuited flash capacitor.
