Latest Patents
One of Hisashi Tsukagoshi's latest patents is for an optical printhead. This invention features a circuit board that holds a line of light-emitting elements mounted at a predetermined height. A rod lens array extends longitudinally, forming images of the light-emitting elements on a photoconductive body. The design ensures that the images and light-emitting elements create pairs of conjugate points with respect to the rod lens array. Additionally, the supporting members are strategically mounted to hold the rod lens array relative to the circuit board, accommodating any warp or distortion.
Another significant patent is for an LED print head and its method of adjusting focus. This LED print head is designed for use in LED printers and includes an LED circuit board with multiple LED chips mounted in line. A lens assembly with rod lenses focuses the emitted light onto a photosensitive drum. The design allows for stepwise displacement of either the LED circuit board or the lens assembly, ensuring precise alignment with the photosensitive drum.
