摘要：
A one-time-use camera comprises a filmstrip and an electronic flash with a concave-shaped flash reflector having a front open end, a flash illumination-producing flash tube inside the flash reflector, and a light-transmitting flash cover-lens over the front open end of the flash reflector. The flash reflector has film identifying indicia visible from outside the camera to identify the filmstrip, which are light-reflecting to the same extent as the flash reflector in order to reflect flash illumination produced by the flash tube in concert with the flash reflector. The flash reflector is adhered to the flash tube to prevent the flash reflector from being separated from the flash tube without breaking the flash tube, whereby removal of the film identifying indicia in effect destroys the electronic flash.
