Abstract

An autofocus apparatus according to an embodiment of the present invention includes a reflector provided to a rear side of a lens assembly and configured to change a path of a light passing through the lens assembly so that the light is oriented toward an image sensor; a carrier to which the reflector is mounted, the carrier being configured to linearly move in an optical axis direction; a housing configured to accommodate the carrier; and a driving unit configured to move the carrier so that a distance between the reflector and the lens assembly and a distance between the reflector and the image sensor are changed simultaneously.
