Then the cassette is moved from the inside to the outside of the cassette container 21 against both retaining springs 33. Then both cam levers 29 are moved and both rocking plates 23 are turned by its own weight and both the cassette guides 22 are escaped automatically downward from the inside of the cassette container 21.
