Title: Eiji Hoshinaka: Innovator in Recording Medium Technology
Introduction
Eiji Hoshinaka is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of recording medium technology, holding a total of 3 patents. His work focuses on improving the mechanisms involved in optical disc handling and switching devices.
Latest Patents
Hoshinaka's latest patents include a recording medium driving device that features an improved disc feeding mechanism. This innovative drive 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 dual mechanism 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 when the cam member reciprocates. This design prevents the switch from being affected by hysteresis caused by directional differences in the contact point.
