Image photographing device including diaphragm

An image photographing device comprising:

• a lens holder including a lens group and a coil unit that generates an electromagnetic force;
• a housing, into which the lens holder is movably inserted, including a magnet that faces the coil unit;
• an image sensor converting an optical image obtained through the lens group into an electrical signal;
• a diaphragm attached to the housing, elastically supporting the lens holder which moves in the direction of an optical axis by the electromagnetic force;
• and
• a terminal unit connected to a terminal of the coil unit by being located outside the diaphragm, applying power to the coil unit.

An image photographing device comprising:

• a first lens holder including a first lens group and a first coil unit that generates an electromagnetic force, the first lens holder moving in the direction of an optical axis to adjust zooming magnification;
• a second lens holder including a second lens group and a second coil unit that generates an electromagnetic force, the second lens holder moving in the direction of the optical axis to adjust focusing;
• a housing, into which the first and second lens holders are movably inserted, including magnets that face the first and second coil units;
• an image sensor converting optical images obtained through the first and second lens groups into electrical signals;
• a first diaphragm attached to the housing, elastically supporting the first lens holder which moves in the direction of the optical axis upon control of the magnification of the first lens group;
• a second diaphragm attached to the housing, elastically supporting the second lens holder which moves in the direction of the optical axis upon control of the focus of the second lens group, and
• terminal units which apply power to the first and second coil units and are connected to terminals of the first and second coil units by being located outside the first and second diaphragms,
• wherein the first and second diaphragms are formed of nonmetal.
