ングの先端部をキヤツプで蓋閉し、このキヤツプ
に開設した光透過孔を介して上記発光素子からの
光が外部へ出射されるとともに、その反射光が上
記光透過孔を介して上記受光素子へと導かれる光
学読取装置において、上記キヤツプが樹脂成形品
であつて、このキヤツプの上記光透過孔に少なく
とも露出面が湾曲面を呈するレンズが圧入してあ
るとともに、これらのキヤツプおよびレンズの露
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.
