OPTICAL APPARATUS AND IMAGE PICKUP APPARATUS HAVING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027728 titled 'OPTICAL APPARATUS AND IMAGE PICKUP APPARATUS HAVING THE SAME

Simplified Explanation

The abstract of the patent application describes an interchangeable lens that consists of three guide units and a rear unit base. Each guide unit includes a pair of guide members, with one member in each unit. The lens is divided into three regions around the optical axis: the first region where one member of the first guide unit is located, the second region where one member of the second guide unit is located, and the third region where one member of the third guide unit is located. The other member of the second guide unit is positioned in the first region, the other member of the third guide unit is positioned in the second region, and the other member of the first guide unit is positioned in the third region.

  • The patent describes an interchangeable lens with multiple guide units and a rear unit base.
  • Each guide unit consists of a pair of guide members.
  • The lens is divided into three regions around the optical axis.
  • One member of each guide unit is positioned in a specific region.
  • The other member of the second guide unit is positioned in the first region.
  • The other member of the third guide unit is positioned in the second region.
  • The other member of the first guide unit is positioned in the third region.

Potential Applications:

  • Camera lenses
  • Microscope lenses
  • Telescope lenses

Problems Solved:

  • Allows for easy interchangeability of lenses
  • Provides precise positioning of guide members

Benefits:

  • Simplifies lens changing process
  • Ensures accurate alignment of guide members
  • Enhances overall lens performance


Original Abstract Submitted

an interchangeable lens comprises a first to a third guide units, and a rear unit base. each of the first to third guide units includes a pair of guide members including one member and the other member, there are three regions divided in a circumferential direction around the optical axis, a region in which one member of the first guide unit is disposed is defined to as a first region, a region in which one member of the second guide unit is disposed is defined to as a second region, and a region in which one member of the third guide unit is disposed is defined to as a third region. the other member of second guide unit is disposed in first region, the other member of third guide unit is disposed in second region, and the other member of first guide unit is disposed in third region.
