Latest Patents
Takayuki Ohsawa's recent patents reflect his commitment to innovation:
1. **Optical Scanning Apparatus**: This apparatus comprises a light source that emits a laser light ray and a cylinder lens that converts this ray into a first convergent light ray, which is adjusted to converge only in the sub-scanning direction. Key components include a deflection unit for redirecting the convergent ray, a focusing unit for refining the light into a second convergent light ray aimed at a scanned surface, and an aperture unit designed to block peripheral portions of the laser light, ensuring precise focus. An adjusting unit allows for regulation of the aperture width to maintain consistency with design specifications.
2. **Optical Scanner for Image Recording Apparatus**: This invention features a deflecting device that reflects and directs a laser beam towards a target surface, forming an accurate beam spot. It incorporates a first aperture to ensure the correct diameter of the beam spot is achieved on the target surface and a second aperture to further fine-tune the diffraction light intercepted during the sub-scanning process.
