ABSTRACT:
A one-time-use camera comprises a resistive heating element positioned to apply sufficient heat to a critical component of the camera, such as a plastic taking lens, to permanently damage the component when a battery in the camera is connected to the heating element, and a normally open switch which is closed to connect the battery and the heating element after the last available frame of a filmstrip in the camera has been exposed.
