Scanning lens apparatus adopting bimorph actuator

A scanning lens apparatus with a bimorph actuator, the scanning lens apparatus comprising:

• a housing having a hollow cylindrical shape;
• a first suspension and a second suspension which are parallel to each other, and a first end of the first suspension and a first end of the second suspension are fixed on an inner surface of the housing;
• first bimorphs disposed on first surfaces of the first suspension and first bimorphs disposed on first surfaces of the second suspension, and second bimorphs disposed on second surfaces facing the first surfaces with respect to the corresponding first suspension and the corresponding second suspension;
• a first lens which is fixed between a second end of the first suspension and a second end of the second suspension;
• a third suspension and a fourth suspension, wherein a first end of the third suspension and a first end of the fourth suspension is fixed on the inner surface of the housing by forming a second axis with respect to a first axis that is formed by connecting the first suspension and the second suspension;
• third bimorphs disposed on first surfaces of the third suspension and third bimorphs disposed on first surfaces of the fourth suspension, and fourth bimorphs disposed on second surfaces facing the first surfaces with respect to the corresponding third suspension and the corresponding fourth suspension;
• a second lens which is fixed by a second end of the third suspension and a second end of the fourth suspension and the second lens is parallel to the first lens;
• and
• an object lens disposed on an end of the housing to face the second lens with respect to the first lens.
