ードパネルが閉じている状態を示す断面図である。FIG. 1 shows an exploded perspective view. In FIG. 1, a support shaft 5b of the second guard panel 6 is fitted into a support shaft bearing 1h provided at the front opening of the cassette 1, and the support shaft 5h is provided with a gear portion 5. Also, the support bearing 1α of the cassette 1
The support shaft 4α of the first guard panel 2 is fitted into the support shaft 4α. A gear portion 4 is provided on the support axis line A-A of the support shaft 4α, and the gear portion 4 is configured to mesh with the gear portion 5 described above. FIG. 2 is a sectional view showing the guard panel of the embodiment shown in FIG. 1 in a closed state.
