摘要： An optical scanning device includes a third fθ lens, an adjusting bar, a pressing portion, a columnar member, and a movement restraining section. The adjusting bar is disposed parallel with a longitudinal direction of the third fθ lens and has projections which are capable of pressing against the third fθ lens at plural points in the longitudinal direction of the third fθ lens. The pressing portion and the columnar member press the adjusting bar against the third fθ lens. The movement restraining section is configured to set the pressing portion and the columnar member in a first state in which the pressing portion and the columnar member are movable in a direction parallel with the longitudinal direction of the third fθ lens or in a second state in which the pressing portion and the columnar member are restrained from moving.

摘要： An imaging lens good in mass-productivity, compact, low in manufacturing cost, good in aberration performance is provided by effectively correcting aberrations without greatly varying the variation of the thickness of a curing resin. An imaging device having such an imaging lens and a portable terminal are also provided. A third lens (L3) has a flat surface on the object side, a convex surface near the optical axis on the image side, and a concave aspheric surface around the peripheral portion within the region where a light beam passes. Therefore, it is possible to reduce the other optical aberrations such as distortion and simultaneously to design the imaging lens so that the astigmatism takes on a maximum value at the outermost portion. Hence, the resolutions at low to middle image heights are high. In addition, such a shape does not cause a large variation of the thickness of the third lens (L3) from the region along the axis to the periphery. Therefore, the thickness of the third lens (L3) can be small, and the material cost can be reduced.

摘要： F-theta lenses, included in scanning lens systems, are arranged on a main scanning plane facing an optical deflector and substantially linearly symmetrically on the main scanning plane with reference to a rotational center of the optical deflector. Each f-theta lens has a no-power portion in the main scanning direction. Synchronization-detecting light passes through the no-power portion of the f-theta lens, thus enabling reduction in color shift due to temperature variation in an image forming apparatus without increasing the cost and complexity in controlling color shift.
