In the case portion 3, light shielding portions 35 are provided at positions opposite to the light sources 4A between the indexes 20 and the light sources 4A. At least a part of outer peripheral portion 36 of the light shielding portion 35 has an arc-shape which keeps a fixed distance from an outer peripheral portion 31 of the recessed portion 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
