Latest Patents

Among his latest patents is a "Laser scanning optical apparatus having exclusive optical elements at varying distances from receiving surfaces." This invention involves a laser scanning optical apparatus where multiple beams are deflected by a single polygon mirror and scanned onto corresponding photosensitive drums through a sophisticated scanning optical system. The system includes a first scanning lens that transmits all beams, along with exclusive second scanning lenses that transmit specific beams. The design allows for varying distances between the optical elements and the photosensitive drums, enhancing the efficiency of the scanning process.

Another notable patent is the "Tandem scanning optical device." This invention enables the deflection of multiple laser beams and their scanning of photoreceptors in the main scanning direction, while also separating the light paths in the sub-scanning direction. The device achieves this by having multiple laser beams strike the same reflective surface at different angles, allowing for precise adjustments in both incident angles and positions.
