Abstract:
A lens moving apparatus can include a housing; a base disposed below the housing; a bobbin disposed inside the housing and configured to move in a first direction along or parallel with an optical axis within the housing; driving magnets disposed on the housing; a coil provided at an outer surface of the bobbin; an elastic member coupled to the bobbin and supporting the bobbin; a sensing magnet coupled to the bobbin; and a position sensor coupled to a printed circuit board, wherein the position sensor is configured to sense a displacement of the sensing magnet in the first direction, in which the bobbin includes a reception recess formed on the outer surface of the bobbin such that at least a part of the reception recess is located at an inside of the coil, the sensing magnet is disposed in the reception recess, and the position sensor is disposed on another side of the housing than sides on which the driving magnets are disposed.
