One-time-use camera with viewfinder incapacitated when rear cover part removed to load fresh film in camera

摘要

A one-time-use camera comprising a main body part, a cover part that can be separated at least partially from the main body part, and a viewfinder having a pair of front and rear viewing lenses optically aligned for viewing a subject to be photographed, is characterized in that the cover part is connected to one of the front and rear viewing lenses to move the one viewing lens out of optical alignment with the other viewing lens when the cover part is separated at least partially from the main body part, whereby the one viewing lens can be readily identified to prevent the viewfinder from being erroneously reused. Preferably, the one viewing lens is connected to the main body part in addition to being connected to the cover part in order to hold the cover part to the main body part. A fracture line of weakness exists between the one viewing lens and the main body part which is broken when the one viewing lens is moved out of optical alignment with the other viewing lens.
