出面に光透過性を有するハードコーテイング材が
塗膜してあることを特徴とする光学読取装置。 The tip of the main body casing containing the light-emitting element and light-receiving element is covered with a cap, and the light from the light-emitting element is emitted to the outside through a light transmission hole made in the cap, and the reflected light is reflected from the light-emitting element to the outside. In the optical reading device that is guided to the light receiving element through a light transmission hole, the cap is a resin molded product, and a lens having at least an exposed surface exhibiting a curved surface is press-fitted into the light transmission hole of the cap. An optical reading device characterized in that the exposed surfaces of these caps and lenses are coated with a hard coating material having optical transparency.
