Abstract
Abstract A recyclable single-use camera in which a front casing portion is separable from a main body portion to replace a taking lens during recycling of said camera, is characterized in that the taking lens has a front lens element and a rear lens element. The rear lens element is secured to the main body portion in order to prevent removal of the rear lens element. The front casing portion holds the front lens element in optical alignment with the rear lens element, and permits removal of the front lens element to allow it to be replaced whenever the front casing portion is separated from the main body portion during recycling of the camera.
