摘要： An image forming apparatus includes a space portion for stacking sheets thereon, and is constituted of an image forming portion and an image reading portion including first and second scanning optical systems therein. In the image forming apparatus, the image reading portion is loaded on three points that correspond to both corners on the scanning start position side and one corner on the apparatus rear side. This configuration allows the first and second scanning optical systems to compensate for each other's misalignment, thereby obtaining stable output images.

摘要： There is provided a method of manufacturing a ridge type LC-DFB semiconductor laser in which a laser substrate having a cladding layer made of a material for a ridge stripe formed on an active layer made of semiconductor. A stripe mask is formed on the cladding layer to form two lateral flat portions from the cladding layer, by a selective wet etching, so as to form a ridge stripe protruding therefrom and having a flat top portion at which the stripe mask capped. A grating mask is formed on the two lateral flat portions, side walls of the ridge stripe and the stripe mask. The grating mask has a periodic structure in the direction in which the ridge stripe extends. The two lateral flat portions and the side walls of the ridge stripe are dry-etched through the grating mask and then the two lateral flat portions and the side walls of the ridge stripe are wet-etched to form a grating of the material for the ridge stripe on the two lateral flat portions, the side walls of the ridge stripe and the active layer, so as to define a bracket grating portion adjacent to the ridge stripe.
