Patent Images

1. An information processing apparatus comprising:

  • a projection unit configured to project an image;

    a mirror unit provided with a mirror that reflects the image projected by the projection unit towards a projection surface;

    a detection unit configured to detect motion of a detection target in a projection area of the projection unit via the mirror;

    in an in-plane direction of the mirror, letting a first direction be a projection line direction when an optical axis of the projection unit is projected onto the plane of the mirror, and in the in-plane direction of the mirror, letting a second direction be a direction that is perpendicular to the first direction,a first supporting unit configured to support the mirror and to be connected to the mirror on a side on which the projection unit is arranged relative to an intersection point between the optical axis of the projection and the mirror in the first direction; and

    a second supporting unit configured to support the mirror and to be connected to the mirror unit on the side on which the projection unit is arranged relative to the intersection point between the optical axis of the projection and the mirror in the first direction, and at a position that is different from the first supporting unit in the second direction,wherein the first supporting unit and the second supporting unit are provided such that in a state in which the first supporting unit and the second supporting unit are attached to an apparatus main body, letting a side of the first supporting unit and the second supporting unit attached to the apparatus main body be a fixed end, and letting the side of the first supporting unit and the second supporting unit attached to the mirror unit be a free end, a primary natural frequency in a case in which the free ends of the first supporting unit and the second supporting unit vibrate in the second direction is lower than a primary natural frequency in a case in which the free ends of the first supporting unit and the second supporting unit vibrate in the first direction.
