Abstract

The present application relates to an optical element module and an image pickup device, wherein, the optical element module includes an optical element, and a plurality of actuator elements. In the module, the plurality of actuator elements are arranged such that a direction of width of the oblong strip shape of the plurality of actuator elements is a direction of the optical axis and such that a direction of thickness of the plurality of actuator elements is perpendicular to the optical axis, another end part in a direction of length of the plurality of actuator elements is fixed such that one end part in the direction of length of the plurality of actuator elements is displaced by the bending to move the optical element, and at least one actuator element A of the plurality of actuator elements is disposed such that a direction in which the one end part of the actuator element A is displaced by the bending (X-direction) is orthogonal to a direction in which the one end part of another actuator element B is displaced by the bending (Y-direction).

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2007-260589 filed in the Japan Patent Office on Oct. 4, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an optical element module using a polymer actuator element and an image pickup device for hand movement correction using the optical element module. Background technique [0004] As the number of pixels has increased and features have improved, hand movement correction has begun to become the standard in digital cameras. In particular, optical hand movement correction has recently been added in addition to digital hand movement correction (for example, see Japanese Patent No. 3516110, hereinafter referred to as "Patent Document 1"). [0005] However, in the case of optical hand movement correction, an actuator mechanism utilizing magnetism (such as a...
