摘要： An optical scanning device for guiding a light beam to a member to scan the member with the light beam, including a light source emitting the light beam; a light deflector deflecting the light beam; a focusing optical system including a plastic optical element molded using a die. The optical element has least two transfer surfaces formed by contacting with transfer surfaces of the die and including a light entrance surface and a light exit surface; and a third surface including a non-transfer surface formed without contacting a transfer surface of the die. The light beam passes through the optical element in such a manner that the optical axis center of the light beam extends in a direction parallel to the shorter side of the optical element while being shifted from the dimensional center of the optical element toward the third surface of the optical element.

摘要： A plastic lens molded in a mold having two first molding blocks and two second molding blocks. The first molding blocks transfer light incidence and emission surfaces. The second molding blocks are provided to both ends of the first molding blocks, disposed parallel to an optical axis and facing each other, and transfer non-light-passing surfaces. At least one of the second molding blocks includes an elongated slit-like ventilation hole having a length of a light effective range or longer and extending in a main scanning direction of the light incidence and emission surfaces along positions equidistant from the light incidence and emission surfaces. Through the ventilation hole, air is sprayed onto molten resin in a process of resin cooling and solidification to facilitate cooling of the resin.

摘要： There is provided an injection mold for molding an optical component including an optical surface, a non-optical surface separated from the optical surface, and a rib provided to an edge portion of the optical surface, and longer in a direction parallel to the optical surface than in a direction perpendicular to the optical surface. The mold includes a transfer piece including a transfer surface that molds the optical surface and a movable cavity piece including a non-transfer surface that molds at least a portion of the non-optical surface. The transfer surface and the non-transfer surface define a cavity to be filled with resin. The movable cavity piece is moved away from the resin during a process of cooling the resin. At least a portion of the non-transfer surface is located closer to the rib than a boundary between the transfer surface and the rib.
