Lens barrel

摘要

A lens barrel (1) comprises an actuator (430), and an image blurring correction device (500) provided near the actuator (430). The image blurring correction device (500) has a magnetic sensor (524), a magnet (515), and a shield plate (514). The shield plate (514) comprises a main body (514a) that is opposite the magnet (515), and a protrusion (514b) that protrudes from the main body (514a). The main body (514a) is provided at a position through which pass lines of magnetic force generated from a first magnetic pole, out of the lines of magnetic force produced from the actuator (430). The protrusion (514b) is provided at a position through which pass lines of magnetic force generated from a second magnetic pole, out of the lines of magnetic force produced from the actuator (430).

1. A lens barrel, comprising:
a fixed frame; a movable frame configured to move relative to the fixed frame; an actuator having a first magnetic pole and a second magnetic pole; and an image blurring correction device having a magnetic sensor disposed near the actuator and configured to detect the position of the movable frame, a magnet that is disposed between the actuator and the magnetic sensor at a position that is juxtaposed to the magnetic sensor, a shield plate having a main body that is provided between the actuator and the magnet and is disposed at a position that is juxtaposed to the magnet and a protrusion that protrudes from the main body, wherein the main body is provided at a position through which pass lines of magnetic force generated from the first magnetic pole of the actuator when the actuator is driven, and the protrusion is provided at a position through which pass lines of magnetic force generated from the second magnetic pole of the actuator.
