PROBLEM TO BE SOLVED: To provide an information processing device that can reduce an influence of a vibration.SOLUTION: An information processing device comprises: a projector 106 that projects an image; a mirror unit that includes a mirror 117 that reflects the image to be projected toward a projection plane; a gesture sensor 107 that detects a movement of a hand in an area around the projection plane on the basis of reflection light from the mirror; and, in an in-plane direction of the mirror, when setting a direction of a projection line in projecting the optical axis of the projection unit to a first direction, and a direction orthogonal to the first direction to a second direction, with respect to the first direction, a side frame 114a that supports the mirror on a side where the projection unit is arranged further than an intersection point between an optical axis of the projection unit and the mirror, and a side frame 114b that supports the mirror on the side where the projection unit is arranged further than the intersection point between the optical axis of the projection unit and the mirror and at a position different from a first support section with respect to the second direction. The side frame is provided so that natural vibration frequency with respect to the second direction is lower than natural vibration frequency with respect to the first direction.SELECTED DRAWING: Figure 5 |
