Problems solved by technology

[0005] However, for example, in optical systems such as small devices mounted on portable electronic devices, such as medium-range telephoto systems with long optical lengths, the hand-shake correction mechanism exists due to the length of the driving amount and the weight of the lens, and it is difficult to reduce the thickness of the integrated mechanism. , the topic of miniaturization
[0006] In addition, since the autofocus mechanism for adjusting the focus that is driven in the direction of the optical axis is integrated with the lens movement and hand-shake correction mechanism that drives the lens on a plane perpendicular to the optical axis, it is also necessary to suppress the respective Due to the adjustment of the inherent vibration mechanism and the centering of the lens, etc., the necessity of precise assembly and the difficulty of design also tend to increase.
[0007] It can further be mentioned that since the autofocus mechanism for adjusting focus driven in the direction of the optical axis and the lens movement hand-shake correction mechanism driven in a plane perpendicular to the direction of the optical axis can move the lens barrel three-dimensionally, the drop When the shock countermeasure is difficult, etc.
[0008] In order to solve these problems, there is a mechanism for driving the imaging element, but in the structure using a leaf spring as the supporting member, the deformation at the time of dropping may hinder the normal driving, and the weight of the upper lens unit may cause inclination and sinking. enter

Abstract

An anti-vibration mechanism for an imaging device is provided in an imaging device including a camera shake correction mechanism. Provided is an optical system which, in an imaging device provided with an optical system that moves in the direction of an optical axis and includes a focus adjustment mechanism, has an anti-vibration mechanism that performs camera shake correction by preventing vibration of an imaging element, and which, in order from the object side, is provided with an imaging lens group, an anti-vibration mechanism, and an imaging element on the anti-vibration mechanism. The image pickup element on the anti-vibration mechanism is rotated with respect to the optical axis of the image pickup lens group, and camera shake correction is performed.

Description

technical field [0001] The present invention relates to an anti-vibration mechanism for an imaging device with a hand shake correction function, an optical system, a camera and electronic equipment. Background technique [0002] With the rapid development of photographing technology, photographing devices including lens drive are widely used in a large number of photographing devices. Various portable electronic devices (such as cellular phones, tablet computers, etc.) employing lens-driven imaging devices are particularly popular with consumers. [0003] The driving mechanism of the lens driving device suitable for ordinary portable electronic equipment is generally composed of an autofocus mechanism that adjusts the focus in the direction of the optical axis and a hand-shake correction mechanism that drives in a plane perpendicular to the direction of the optical axis. [0004] These two functions are formed by a coil and a magnetic steel, and the coil is fixed on the per...
