The first front cover has a distal end which is situated on an outer side of the casing when the insertion slot is closed, the second front cover has a distal end which is situated on an inner side of the casing when the insertion slot is closed, and the second front cover is rotated with a radius of rotation which differs from that of said first front cover.
