Latest Patents

One of Kitajima's latest patents is an optical module and camera module. This invention discloses an optical unit that can be easily assembled, allowing its optical element to move smoothly while preventing friction loss around its nut member. The lens driving apparatus he developed is designed to move an optical element holder along a guide member, utilizing a nut that is integrally provided at the holder and a lead screw that is threadedly coupled to the nut. This mechanism enables the optical element to be moved in the extension direction of the optical axis, with the motor's forward or backward rotation transmitted to the lead screw via a reduction gear train. The lead screw is also designed to be inclinedly movable, enhancing its functionality.

Another significant patent by Kitajima is a coordinate reader and method of detecting coordinates. This invention comprises a coordinate detector body with excitation and detection lines, an exciting circuit, and a signal processing circuit. The control circuit processes the signals to output an excitation control signal, while a phase detecting circuit ensures the accuracy of the coordinates by eliminating induction signal components due to direct electromagnetic coupling. This innovative structure enhances the precision of coordinate detection and reduces the read invalid region.
