摘要： An optical scanning device includes: a light source device that emits five light beams corresponding to four basic colors and a single specific color; and five scanning optical systems corresponding the five light beams. One light beam in a first waveband among the light beams corresponding to the four basic colors enters one scanning optical system of the five scanning optical systems. The one scanning optical system includes a dichroic mirror that transmits a light beam in a second waveband different from the first waveband. An angle θb formed between a normal to the incidence plane of the dichroic mirror and orthogonal projection to an assumed plane orthogonal to the main scanning corresponding direction of the incident path of the light beam to the incidence plane of the dichroic mirror is set at an angle of 0° or more and an angle of 45° or less.

摘要： If inclination correction of scanning line is performed while the incident position of the laser beam is not suitable, the shape of a spot of the laser beam which forms an image on a photosensitive drum may not be uniform depending on the scanning position of the laser beam. The housing is provided with a U-shaped groove to which the convex portion of a lens hold member that holds the lens is engaged. With the position of the convex portion adjusted, the convex portion is attached and secured in the U-shaped groove. Thus, the installation position of the lens to an optical path of the laser beam is adjusted, and the lens can be rotated and adjusted in order to correct an inclination or a bending of scanning line.

摘要： An single-pass imaging system utilizes a light source, a spatial light modulator and an anamorphic optical system to form a substantially one-dimensional high intensity line image on an imaging surface (e.g., the surface of a drum cylinder). The light source and the spatial light modulator are used to generate a relatively low intensity two-dimensional modulated light field in accordance with an image data line such that each pixel image of the line is elongated in the process (Y-axis) direction. The anamorphic optical system utilizes a cylindrical/acylindrical optical element to anamorphically image and concentrate the modulated light field in the process direction to form the substantially one-dimensional high intensity line image. The line image is generated with sufficient energy to evaporate fountain solution from the imaging surface. The imaging system simultaneously generates all component pixel images of the line image, thus facilitating a printing apparatus capable of 1200 dpi or greater.

摘要： If an open-close lid is opened to perform cleaning for wiping the dirt off reflection surfaces of a polygon mirror, a service staff has difficulty in cleaning the reflection surfaces of the polygon mirror since the polygon mirror is located inside a housing. To respond to such an issue, a positional relationship between an installation position of the polygon mirror and an opening is set such that at least one of the reflection surfaces of the polygon mirror is exposed to the outside of the housing.
