摘要： An optical scanning apparatus includes a light source for radiating a light beam, an optical scanning system for deflecting the light beam from the light source and condensing the light beam on a surface to be scanned, a detecting device for detecting an image forming state of the light beam scanned by the optical scanning system, and an adjusting mechanism for adjusting the focal position of the light beam on the surface to be scanned. The detecting device includes a very low cost detecting element that can accurately detect an image forming state of the light beam scanned by the optical scanning system independently in a main scanning direction and in a sub scanning direction. While the focal position of the light beam is changed continuously or at a predetermined pitch by the adjusting mechanism, the detecting device monitors the image forming state of the light beam and detects the location and vicinity of a light beam waist position relative to a desired position on the surface to be scanned.

摘要： An image forming system utilizing a light emitting diode (LED array) having LEDs arranged along a curved line. The LEDs are either edge emitting type LEDs or surface emitting type LEDs. The LEDs of the LED array emit light towards a center or optical axis of the lens. A plurality of lenses are connected together to form a lens array. Alternatively, two lens arrays can be utilized. If two lens arrays are utilized, each of the lenses in the lens array includes an aspherical surface. The curved LED array prevents the flaring of light and produces an even pattern of light emission on a light receiving surface such as a photoconductive drum.

The optical system includes a first optical device, a second optical device made of a resin material which has an anamorphic negative refracting power in a deflection scanning direction and a deflection scan perpendicular direction and has a larger refracting power in the deflection scan perpendicular direction than a refracting power in the deflection scanning direction, and a third optical device made of a glass material which has substantially no refracting power in the deflection scanning direction and a positive refracting power in the deflection scan perpendicular direction. An interval of the scanning lines formed on the scanned surface is adjusted by displacement of the second and third optical devices in an optical axis direction of the before-light-deflecting-unit optical system.
