Abstract
After loading a film cassette into a cassette chamber, a lid of the cassette chamber is closed. Interlocking with the lid, a lid lock member is moved to a lock position to lock the lid. When the lid lock member is moved to the lock position, a shutter lock member allows to operate a shutter release button. When the shutter release button is operated, a shutter is driven and a photo film is advanced. When the lid lock member is moved to an unlock position, the lid is opened. When the cassette chamber is opened, the shutter lock member prevents the operation of the shutter release button to prohibit the advancing of the photo film.
