Abstract

The present invention provides a lens barrel capable of realizing miniaturization, an imaging device and an information terminal. The lens barrel includes : a first zoom lens; a second zoom lens; a first zoom lens supporting barrel that supports the first zoom lens; a second zoom lens supporting barrel that supports the second zoom lens; a moving member that moves the first zoom lens supporting barrel and the second zoom lens supporting barrel in an optical axis direction of the first and second zoom lens supporting barrels; a first projected section that is provided in one of the first zoom lens supporting barrel and the moving member to cross the optical axis direction and engages with a first groove section provided in the other; and a second projected section that is provided in one of the second zoom lens supporting barrel and the moving member to cross the optical axis direction and engages with a second groove section provided in the other.

Description

technical field [0001] The invention relates to a spectacle frame with a plurality of zoom lens support frames movable in the direction of the optical axis, and an imaging device with the spectacle frame. Background technique [0002] In recent years, imaging devices have been required to be smaller, lighter and more functional in order to be mounted on mobile phones and the like. As a technique for solving this problem, for example, Patent Document 1 discloses a technique related to an imaging device equipped with a compact zoom mechanism using a thinned curved optical system. [0003] In the technology disclosed in Patent Document 1, the zoom mechanism has a shaft-shaped cam member and a motor that rotates the cam member, wherein a cam portion for determining the position of the moving lens frame is formed on the outer peripheral surface of the cam member, and the cam member is arranged such that A portion is at least axially adjacent to a side of the reflective optical e...
