Abstract

A lens-fitted photo film unit has a cassette containing chamber and a photo film roll chamber. The cassette containing chamber contains a cassette. The cassette has a spool and a cassette shutter. A photo film is secured to the spool contained in the cassette in a rotatable manner. The cassette shutter is incorporated in a rotatable manner between a closed position to block a photo film passage port and an open position to open the photo film passage port. The lens-fitted photo film unit has a rotatable photo film winding wheel, of which a wheel portion is disposed above the cassette containing chamber, and externally rotated after a frame on the photo film is exposed. A first rotational shaft projects downwards from the wheel portion, and is engaged with the spool through a top wall of the cassette containing chamber. The wheel portion is rotated to wind the photo film into the cassette. A rotating member has a second rotational shaft, is connected with the cassette shutter through the top wall of the cassette containing chamber, and rotates the cassette shutter from the open position to the closed position. Arc-like ridges project on the top wall of the cassette containing chamber, and support the wheel portion thereon. The wheel portion is located away from the top wall of the cassette containing chamber. The rotating member is contained between the wheel portion and the top wall at least partially.
