摘要： There is provided an optical module having a circuit board that includes an imaging element, a lens barrel that is fixed onto the circuit board to movably accommodate a lens holder having a lens that forms an image on an imaging surface of an imaging element in a light axis direction, a cylindrical cam having a cam surface engaged with a protrusion disposed in the outside of the lens barrel and extending from a side face of the lens holder to move the lens holder, and a drive section in which an actuator drives the cylindrical cam via a gear train and also having a cover that integrally covers the lens barrel and the actuator and determines the positional relationship between the lens barrel and the drive section.

摘要： The rotational torque of an electromagnetic actuator having a stator and rotor, such as a stepping motor, is increased. The electromagnetic actuator includes a rotor (30) having multiple magnetic poles (Nr1, Nr2, Nr3, Nr4, Nr5, Sr1, Sr2, Sr3, Sr4, Sr5) on a circumferential surface (31) and a plurality of stators (10, 20) in an electromagnet form. The stator (10, 20) has a pair of magnetic poles (13, 14, 23, 24) facing the circumferential surface (31) of the rotor (30), and an auxiliary yoke (40, 50) made of a soft magnetic material member extending in a circumferential direction (A) over an angular range (γ1, γ2) larger than a spread angle (α) of the magnetic poles (Nr, Sr) of the rotor (30) in the circumferential direction (A) is provided between the pair of magnetic poles (13, 14, 23, 24).
