Latest Patents

Matsushima's latest patents include a lens barrel designed for holding a lens. This innovative lens barrel features a barrel body that contains the lens, with a ring-shaped receiving wall formed on the barrel body. This wall is intended to receive the rear face of a peripheral portion of the lens, ensuring proper positioning in the optical axis direction. The design incorporates three retaining claw portions that project from the barrel body, effectively retaining the lens on the receiving wall through engagement with its peripheral portion. Additionally, the barrel body is equipped with three first through holes for the insertion and pressure of an external adjusting rod, allowing for precise positioning adjustments of the lens. Furthermore, second through holes are included for the introduction of adhesive agents to securely attach the lens to the barrel body. The arrangement of the retaining claw portions and the first through holes is meticulously designed at a regular pitch around the circumference of the barrel body.

Another patent focuses on the lens barrel's female helicoidal screw, which is subjected to a biasing force from multiple looseness eliminating springs. These springs are formed on the outer peripheral portion of the lens barrel and are integrally supported by the inner barrel body. The male helicoidal screw is designed to slide while being thrust against the female helicoidal screw, enhancing the overall functionality of the lens barrel.
