Patent attributes
A front bezel includes a main body (10) defining a light-pervious area (142) therein, a light-guiding member (20) secured to the main body, a shielding plate (30), and a gear member (40) rotatably secured on the light-guiding member. The light-guiding member has a light-guiding portion (22) defining a space for securing a light source (60) therein. The space communicates and aligns with the light-pervious area. The light-guiding portion defines a sliding slot (254) communicating with the space, for slidably receiving the shielding plate therein. A plurality of teeth (32) is formed on the shielding plate. The gear member has a plurality of teeth (41) meshing with the teeth of the shielding plate, and is rotatable to slide the shielding plate to cover one portion of the space in which the light source is secured, and thereby prevent light of the light source emitting out of the space.
