AUTO FOCUS LOCKING UNIT AND PHOTOGRAPHING APPARATUS INCLUDING THE SAME

摘要

Provided are an auto focus (AF) locking unit and a photo-graphing apparatus including the AF locking unit. In particular, the AF locking unit supports a lens group barrel holder that is descended by a movement of a front barrel in an optical axis direction by using a locking lever provided with an elastic force, and the photographing apparatus includes the AF locking unit. According to an embodiment, the AF locking unit supports the lens group barrel holder including lenses in the optical axis direction by using a driving force transmitted from a motor in correspondence to movements of a cam barrel and a front barrel, and the photographing apparatus includes the AF locking unit.

主权项

1. An auto focus (AF) locking unit comprising:
a locking protrusion; a locking lever provided in an AF frame accommodating a lens group barrel holder including lenses to be moved in an optical axis direction, and supporting the lens group barrel holder by contacting the locking protrusion when the AF frame is moved to an accommodation location that is adjacent to an image sensor; and a locking lever elastic member providing an elastic force in the optical axis direction to the locking lever in correspondence to the contact between the locking protrusion and the locking lever, wherein when the AF frame is moved toward the accommodation location, a distance between a front surface of the lens group barrel holder and an inner side surface of the AF frame, which faces the front surface of the lens group barrel holder, is reduced.
