    摘要: A semiconductor laser device comprises first current blocking layers formed to define a stripe-shaped current injected region extending in the direction in a front facet from which a laser light is emitted and a rear facet opposing thereto are connected, and a second current blocking layer formed to transverse the stripe-shaped current injected region in the vicinity of the front facet. The first current blocking layers and the second current blocking layer are made of the same layer. Accordingly, a current blocking structure is provided in the vicinity of the facet with the structure which is easily formed, causes no damage on the semiconductor laser device, and minimizes the property degradation, thereby a high facet COD level and high reliability in long-term continuous operations can be achieved.

    摘要: A light irradiation system for irradiating light to an irradiation area extending in a main scanning direction of a document face when placed on an image scanning apparatus includes a light source; a light guiding member to guide light emitted from the light source; and a reflector to reflect a part of light exiting from the light guiding member to the document face. The irradiation area is irradiated by the reflection light reflected by the reflector and a direct light exiting from the light guiding member without reflection at the reflector. The light guiding member includes an incidence surface where the light from the light source enters; and an exit surface where the light entered from the incidence surface exits. The reflector is disposed at a position in a direction that light intensity of light emitting from the light source becomes the strongest.
