Title: Hitoshi Ueno: Innovator in Recording Medium Technology
Introduction
Hitoshi Ueno is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of recording medium technology, holding a total of eight patents. His innovative designs have improved the functionality and efficiency of optical disc drives.
Latest Patents
One of Ueno's latest patents is a recording medium driving device featuring an improved disc feeding mechanism. This device includes a disc ejecting mechanism that efficiently ejects an optical disc from a turntable to a slot. The design incorporates a first disc feeding mechanism located at the rear of the drive unit and a second disc feeding mechanism, or disc guide mechanism, positioned towards the slot. This configuration allows for the transfer of smaller diameter optical discs from the turntable to the slot seamlessly.
Another significant patent involves a switch mechanism and disk device. This switch is designed to be in the "On" position when a contact point is in contact with a cam surface and "Off" when it is at a non-cam surface. A rib is strategically placed near the non-cam surface to change the direction of the contact point during the reciprocation of the cam member. This innovation prevents the switch from being affected by hysteresis caused by directional differences in the contact point.
