OPTICAL IMAGE STABILIZATION UNIT CAPABLE OF BEING MINIATURIZED, LENS BARREL, AND OPTICAL APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18357323 titled 'OPTICAL IMAGE STABILIZATION UNIT CAPABLE OF BEING MINIATURIZED, LENS BARREL, AND OPTICAL APPARATUS

Simplified Explanation

The abstract describes an optical image stabilization unit that can be miniaturized. The unit consists of a fixed member, a lens, a movable member that holds the lens and can move on a plane perpendicular to the optical axis direction, a position detection sensor held by the movable member, and a flexible printed wiring board. The flexible printed wiring board includes a fixed side holding portion, a movable side holding portion, a bending portion that connects the fixed and movable side holding portions, and a sensor mounting portion for the position detection sensor.

  • The patent describes an optical image stabilization unit that can be made smaller in size.
  • The unit includes a fixed member, a lens, and a movable member that holds the lens and can move on a plane perpendicular to the optical axis direction.
  • A position detection sensor is held by the movable member.
  • The unit also includes a flexible printed wiring board with a fixed side holding portion, a movable side holding portion, a bending portion, and a sensor mounting portion.
  • The bending portion and the sensor mounting portion of the flexible printed wiring board overlap each other when viewed from the optical axis direction.

Potential applications of this technology:

  • Miniaturized optical image stabilization units can be used in smartphones, cameras, and other portable electronic devices.
  • It can improve the image quality by reducing blurring caused by hand movements.

Problems solved by this technology:

  • The miniaturization of the optical image stabilization unit allows for its integration into smaller devices without compromising performance.
  • The flexible printed wiring board provides a compact and flexible solution for connecting the position detection sensor.

Benefits of this technology:

  • Miniaturization allows for the implementation of optical image stabilization in smaller devices.
  • The flexible printed wiring board provides a reliable and compact solution for connecting the position detection sensor.
  • Improved image quality by reducing blurring caused by hand movements.


Original Abstract Submitted

An optical image stabilization unit capable of being miniaturized is provided. The optical image stabilization unit includes a fixed member, a lens, a movable member that holds the lens and is movable on a plane, which is substantially perpendicular to an optical axis direction, in the fixed member, a position detection sensor held by the movable member, and a flexible printed wiring board. The flexible printed wiring board includes a fixed side holding portion that is fixed to the fixed member, a movable side holding portion that is fixed to the movable member, a bending portion that connects the fixed side holding portion and the movable side holding portion, and a sensor mounting portion, on which the position detection sensor is mounted. When the flexible printed wiring board is viewed from the optical axis direction, the bending portion and the sensor mounting portion are disposed to overlap each other.
