    摘要： A device for holding a laser diode (LD) and a collimate lens. A laser unit includes an LD supporting section supporting the LD, and a lens supporting section supporting the lens positioned opposite to the LD. A connecting portion connects the lens supporting section to the LD supporting section. An adjustment section for adjusting a relative position between the LD and the lens is provided in association with the LD supporting section. The adjustment section allows the LD supporting section to be movable and position-fixable with respect to the lens supporting section as if the LD supporting section serves as a leverage about the connecting portion functioning as a fulcrum.

    摘要： An optical lens system including a plurality of optical lenses which cooperate with each other to transmit a laser beam deflected in a main scanning direction to scan an object in the main scanning direction, and which include a first lens which is formed of a resin and has a tilt correction function, and at least one second lens which is remoter from the object than the first lens on an optical path. The first lens includes an effective lens portion which has a possibility that the laser beam is transmitted therethrough. The effective lens portion has an incidence surface to which the laser beam is incident in an optical-axis direction, and an outgoing surface from which the laser beam outgoes in the optical-axis direction, and at least one of the incidence surface and the outgoing surface is curved outward in a sub-scanning direction perpendicular to the main scanning direction and the optical-axis direction. The first lens further includes at least one first ineffective lens portion which has no possibility that the laser beam is transmitted therethrough, and which is located adjacent the effective lens portion in the sub-scanning direction. In a cross section of the first lens taken along a plane perpendicular to the main scanning direction, the at least one first ineffective lens portion does not project outward from the outward curved surface of the effective lens portion in the optical-axis direction.

    摘要： A laser generation unit 20 emits a laser beam. A polygon mirror 27 deflects the laser beam to irradiate an image forming surface in horizontal scans. A beam detection mirror 25 reflects the laser beam at a start of each horizontal scan. A slit body 36 has a slit 44 oriented so the laser beam passes therethrough after being reflected off the mirror. A sensor 26 is disposed so that the laser beam falls incident thereon after passing through the slit 44. Light-obstructing walls 35a and 35b of the slit body 36 are slanted an appropriate angle with regards to an optical axis of the laser beam from the beam detection mirror 25. When reflected at the surfaces of the light-obstructing walls, the laser beam will not directly return to the beam detection mirror 25 and then to the polygon mirror 27. Any ghost images will not be formed on the image forming surface.
