Title: Innovations of Yoshihiro Hanada
Introduction
Yoshihiro Hanada is a notable inventor based in Toyokawa, Japan. He has made significant contributions to the field of imaging technology, holding a total of 7 patents. His work primarily focuses on enhancing the functionality and efficiency of image forming apparatuses.
Latest Patents
One of Hanada's latest patents is the "Surface potential control device of photoconductive member." This invention addresses the challenges faced when a photoreceptor in an image forming apparatus is electrified for image formation. The device ensures that the output of a charger starts from a different value than a predetermined value and gradually matches it. Additionally, it controls the charger to start with a lower value corresponding to the time when the charger suspends its operation, ensuring a smooth transition to the predetermined value. This control is achieved by managing the grid voltage flowing into the grid electrode situated between the photoreceptor and the wire electrode used for discharging.
Another significant patent is the "Sheet aligning arrangement." This arrangement is designed to accommodate multiple sheets fed into it for alignment and to feed out the aligned sheets one by one. It includes a feed roller and a first aligning member that can move between two positions: one defining a sheet aligning reference position and the other defining a sheet transport reference position. The second aligning member, which confronts the first, is pivotable in a direction that intersects at right angles with the sheet transport direction. A displacing device is incorporated to facilitate the alignment process and the re-feeding of sheets.
