Latest Patents
One of Hashimoto's latest patents involves a developing device with a contact-enabling mechanism. This innovative device features four developing units arranged along a photosensitive belt that is stretched endlessly. Each developing unit contains toners of different colors and is equipped with a developing roller that faces the photosensitive belt. The contact-enabling mechanism allows for the selective engagement of one of the four developing units with the photosensitive belt. This mechanism utilizes four cams that are arranged out of phase by an angle of 72 degrees, enabling each developing unit to make contact with the belt sequentially. A single driving source rotates the cams, ensuring synchronized operation.
Another significant patent by Hashimoto is for an image forming apparatus that integrally holds an image unit. This apparatus is designed as a color copying machine, featuring four image forming units aligned along the paper sheet's conveyance direction. Each unit includes a photosensitive drum in rolling contact with a conveyor belt, surrounded by various devices such as charging, exposure, developing, transfer, cleaning, and charge removing devices. The image unit is strategically placed between two neighboring photosensitive drums, facilitating the development of electrostatic latent images and the cleaning of the upstream drum.
