Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Such as figure 1 As shown, the camera device 5 is built into the casing of the smartphone 4 . In this embodiment, the camera device 5 is an optical element, and has: lens bodies 2, 200, and 100, which have a common optical axis; performing photoelectric conversion; and a lens driving device 6 that holds the lens bodies 2 , 200 and 100 and the image sensor 1 and drives the lens bodies 200 and 100 with respect to the image sensor 1 . In this embodiment, the camera device 5 further includes a prism 3 which is an optical element that bends light from a subject and guides it into the lens bodies 2 , 200 , and 100 .

[0025] The optical axis direction along the optical axis of the lens bodies 2, 200, and 100 will be appropriately referred to as the Z direction below, and a direction perpendicular to the Z direction will be appropriately referred to as the X direction. The or...

Abstract

The invention provides a lens driving device, a camera device, and an electronic apparatus. A system having a plurality of movable parts can withstand load caused by friction and keeps each movable part at a neutral position. A support mechanism for the lens driving device (6) is provided with two guide shafts (47, 48), first spring members (71, 81) and second spring members (72, 82); two ends ofeach of the guide shafts (47, 48) are affixed to a first fixed section (10) and a second fixed section (20) respectively, extend in an optical axis direction, and penetrate a first movable section (11) and a second movable section (21) respectively; one ends of the first spring members (71, 81) are fixed to the first fixed sections (10) and the other ends of the first spring members (71, 81) are fixed to the first movable sections (11); and one ends of the second spring members (72, 82) are fixed to the second fixed sections (20) and the other end of the second spring members (72, 82) are fixed to the second movable sections (21).

Description

technical field [0001] The present invention relates to a lens driving device, a camera device, and electronic devices used in electronic devices such as smartphones. Background technique [0002] Some camera devices mounted on electronic devices such as smartphones have lens drive mechanisms with various functions such as optical zooming and focusing. Patent Document 1 exists as a document disclosing technology related to such a camera device. In the lens driving device described in Patent Document 1, a coil spring surrounding the guide member is provided between a bearing portion through which one guide member of a movable bracket that slides in the X direction along two fixed shafts passes, and a base stopper. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2013-218751 [0004] However, the technique of Patent Document 1 has a structure in which the movable part is held at a neutral position by the urging force of the coil spring, but it is difficult to apply...
