发明名称 SHAKE CORRECTION DEVICE
摘要 A shake correction device includes a fixed member and movable member. The fixed member has one of three drive coils and three magnets. The movable member has other of the drive coils and the magnets. Three detectors are arranged on the fixed member or the movable member. A movement amount calculator calculates movement amounts and movement directions of operating points in the drive coils. A drive controller moves the movable member to apply to the drive coils based on outputs from the movement amount calculator. The drive coils are arranged such that imaginary lines passing through the operating points in the respective drive coils and parallel to long sides of the respective drive coils cross one another. Each of the detectors is arranged at a position with respect to the corresponding drive coil, where detection direction differs from a direction of a force acting on the operating point.

主权项 1. A shake correction device comprising: a fixed member on which one of three drive coils and three magnets provided to face the three drive coils are arranged; a movable member on which one of an optical element and an image sensor, and other of the three drive coils and the three magnets are arranged, the movable member being movable with respect to the fixed member; three detectors arranged on the fixed member or the movable member on which the three drive coils are arranged, the three detectors arranged to correspond to the respective three drive coils; a movement amount calculator which calculates movement amounts and movement directions of operating points in the three drive coils based on outputs from the three detectors; and a drive controller which moves the movable member by controlling currents to apply to the three drive coils based on outputs from the movement amount calculator, wherein the three drive coils are arranged such that imaginary lines passing through the operating points in the respective three drive coils and parallel to long sides of the respective three drive coils cross one another, and each of the three detectors is arranged at a position with respect to the corresponding drive coil, where detection direction differs from a direction of a force acting on the operating point in the corresponding drive coil.
