ABSTRACT:
A lens-fitted photo film unit has a housing (2), in which a photo film roll chamber and a cassette containing chamber (8, 70) are formed. A cassette incorporates a port shutter (14) rotatable between a closed position of closing a photo film passage port and an open position of opening the passage port. The photo film is wound into the cassette as much as one frame each time one frame is exposed. The cassette is removed from the cassette containing chamber after winding the photo film entirely into the cassette. Through an exit opening, the cassette containing chamber is open externally. An openable bottom lid (7, 66, 75, 80) closes the exit opening, is opened for the removal of the cassette. A rotating mechanism (30, 76, 87, 93; 34, 78, 88, 90; 35, 50, 60, 72, 85) is engaged with the port shutter through a top wall (8a, 70a) of the cassette containing chamber, rotates the port shutter from the open position to the closed position in response to operation opening the bottom lid.
