Abstract

주사 광학장치에 사용되는 렌즈를 아크릴계의 플라스틱을 소재로 하여 사출, 셩형이 가능하도록 하는 주사 광학장치가 개시되는 바, 이는 콜리메이팅 및 원통형 렌즈 그리고, 주사 렌즈를 아크릴계 플라스틱을 소재로 하여 사출 및 성형이 가능하도록 함으로써, 대량 생산 및 제품의 경량화가 가능하고, 가격을 절감하며, 내충격성이 우수해진다. 또한, 형상의 자유도가 높아 렌즈에 적절한 모양의 프레임을 만들 수 있으므로 렌즈 결합 부위를 일체화하여 조립이 용이하고, 일부 렌즈의 형상을 비구면화하는데 용이하다.Disclosed is a scanning optical device that enables injection and shaping of a lens used in a scanning optical device by using an acrylic plastic material, which is a collimating and cylindrical lens, and an injection and molding of a scanning lens using an acrylic plastic material. By making it possible, mass production and weight reduction of the product are possible, cost is reduced, and impact resistance is improved. In addition, since the degree of freedom of the shape can make a frame of a suitable shape for the lens, it is easy to assemble by integrating the lens coupling portion, it is easy to aspherize the shape of some lenses.
