Latest Patents

Among his latest patents is an image forming apparatus that features a separation gear train, fixing gear train, and adjusting gear train operated by a common motor. This apparatus includes a photosensitive drum, a development roller, a separation cam, a fixing device, and an adjusting cam. The development roller is designed to move relative to the photosensitive drum between a contact position and a separate position. The adjusting cam plays a crucial role in switching the nip pressure of the fixing device between first and second pressures. The separation gear train effectively transmits the driving force of the main motor to the separation cam, while the fixing gear train and adjusting gear train transmit this force to their respective components.

Another notable patent involves an image forming apparatus with a development cartridge that is movable by a cam. In this design, the development cartridge can shift between a contact position, where the development roller is in contact with the photosensitive drum, and a separate position. This movement is facilitated by a cam and a cam follower, which slides in directions parallel to the rotation axis of the cam. The cam follower is equipped with a first shaft and a contact arm that interacts with the cam surface, ensuring precise positioning of the development cartridge.
