Description

This product is a one-time use disposable, waterproof camera manufactured by Kodak. It has 23 distinct parts with the majority being made of ABS Plastic and by injection molding.

How It Works

The disposable camera is all mechanical with no electrical components (the exception is a camera with a flash, where a circuit board and battery are included, but that is not the case in this model).

When the photographer depresses the shutter button (which is actually just an extension of the "Viewfinder"), the button moves the "Shutter Lever" to one side, rotating the "Shutter" until the "Shutter Spring" forces the "Shutter Lever" to return to a halfway position. The "Shutter" cannot be rotated again until the "Shutter Lever" is reset. The "Shutter" remains open for only a fraction of a second, as the "Shutter Spring" retracts it as soon as the "Shutter Lever" passes, allowing light to pass through both lenses to the exposed film. During the "Shutter Lever" movement, the "Camshaft" is offset slightly by an extension from the "Shutter Lever" which releases the "Film Advance Lock."

With the picture taken, the photographer winds the "Film Advance Wheel" which rolls up film into the "Film Canister" and clicks off numbers on the "Frame Counter." The film is slotted onto the "Sprocket" which is joined to the "Camshaft" causing both to rotate with the film. When the "Camshaft" rotates a complete cycle, the "Shutter Lever" is reset and the "Film Advance Lock" returns to its original position preventing operation of the "Film Advance Wheel".

The purpose of the "Exterior Front" and "Exterior Back" covers are to protect the camera from the elements. The "Outside Film Advance" allows the rotation of the "Film Advance Wheel" despite the exterior covers. The "Washer" seals the hole between the "Outside Film Advance" shaft and the "Film Advance Wheel"

The "Lens Holder" and "Eyehole Holder" serve to hold their respective components in place. The "Eyehole Cover" allows only a small fraction of the incoming light to be focused on the "Inner Lens" giving a sharper, clearer image.
