1. A visual presenter having a head structure capable of changing a photographing direction, the visual presenter comprising:
a base fixed to a floor by applying weight to prevent the presenter from falling down;
a head part having one end provided with a camera lens facing the floor;
a support part connecting the head part and the base and extending upward from the base to position the head part at a height of a learner's face; and
a photographing mode switching module disposed adjacent to the camera lens and configured to switch between a learner photographing mode and a study material photographing mode without requiring manipulation of the head part, wherein the photographing mode switching module comprises:
a rotating body configured to rotate between a study material photographing mode position and a learner photographing mode position;
a reflective member disposed on a bottom surface of the rotating body;
an angle control body disposed between the rotating body and the camera lens and having an inclined surface supporting the rotating body such that the rotating body remains inclined at a predetermined angle from the camera lens at the learner photographing mode position; and
a hinge arranged between the angle control body and the rotating body and defining a rotation axis of the rotating body;
wherein the rotating body closely contacts a head part member at the study material photographing mode position; and
wherein the rotating body overlaps a lower portion of the camera lens to form an image of an object disposed in front on the camera lens at the learner photographing mode position.
