Abstract

The invention aims to provide a lens driving device which is capable of precisely preventing inclination of a driving shaft and strives to achieve miniaturization, a camera and a mobile terminal device with a camera function. In the lens driving device 1, the front wall of a frame 13 has a square appearance, when seen from a plane at the optical axis side. Two imbed recesses 27 and 27 are formed on the diagonal lines of the square frame 13 via the inner peripheries 27a with a shape identical to that of the outer periphery of a bearing member 12. A shot object holding opening 25 is formed between the imbed recesses 27 and 27. The inner periphery 27a of each imbed recess 27 is formed by a circular arc edge 27b and a linear edge 27c. The linear edges 27c of the opposite inner peripheries 27aof the two opposite imbed recesses 27 are parallel, and the circular arc edges 27b are symmetric relative to the diagonal line E.

Description

technical field [0001] The present invention relates to a lens drive device for moving a focus lens and an optical zoom lens in the direction of an optical axis, a camera, and a mobile terminal device with a camera function. Background technique [0002] Patent Document 1 (JP2009-22287 Publication) discloses a focus lens mount and a zoom lens mount disposed in a frame, which are in frictional contact with a drive shaft respectively, and whose bases are fixed on a vibrating component. In addition, in Patent Document 1, the bearing member holding the tip of each vibrating member is fitted into and fixed in the fitting hole of the frame, and its planar shape is circular when viewed from one side in the optical axis direction. [0003] In the technique of this patent document 1, the outer shape of the front side wall (the side wall in the direction of the optical axis) of the housing is rectangular, and the two bearing members are arranged on the diagonal of the rectangle. At th...
