One-time-use camera with translation-to-rotation converter which is translated first to rotate light lock of film cassette closed and then to eject cassette from camera

摘要

A one time-use camera comprising a film cassette with a light lock that is to be rotated closed after an exposed filmstrip is wound into the cassette, and a driver which initially is rotated to rotate the light lock closed and then is translated to eject the cassette with its light lock closed from the camera, is characterized in that the driver is a translation-to-rotation converter which when initially translated is rotated in response to translation to rotate the light lock closed without translating the cassette and then when further translated is translated without being rotated to eject said cassette with its light lock closed from the camera.
