Title: Shigeru Kojima: Innovator in Optical Disc Technology
Introduction
Shigeru Kojima is a prominent inventor based in Kawagoe, Japan. He has made significant contributions to the field of optical disc technology, holding a total of 8 patents. His innovative designs have advanced the way information is recorded and read from optical discs.
Latest Patents
Kojima's latest patents include a holding device and disk device for recording and reading information. This invention features a support that is substantially cylindrical, designed to be received by a disk hole. It includes a positioning portion on the circumference adjacent to a first axial end, which is equipped with a concave portion that opens to the circumference along a radial direction. Additionally, a first engaging portion protrudes from around the circumference, opposing the positioning portion with a gap equal to or greater than the thickness of an optical disk. A moving member is also incorporated, allowing for movement along the radial direction of the support.
Another notable patent is the transfer control device, transfer control method, transfer unit, and disc unit. This invention includes a disc transfer section for transferring an optical disc by guide members and a transfer roller, positioned adjacent to an opening of a casing. A detector for detecting the optical disc is also included. During the unloading process, the peripheral edge of the optical disc contacts slide members, which are then slid to appropriately switch sensor switches on and off. This mechanism allows for precise control of the drive of a transfer motor based on the movement trajectory of the optical disc.
