PROBLEM TO BE SOLVED: To provide a photographic device which contributes to reduction in cost, by suppressing enlargement of the device and simplifying an optical path configuration, on the assumption that an automatic tracking function suitable for photographing is provided and a three-axis gimbal structure is employed to surely avoid zenith lock. SOLUTION: The photographic device includes a device base 1 which is attached to an airplane or the like and is provided with a bearing part along an AZ axis; a bottom plate part 4 supported freely rotatably by the device base bearing part; a pair of enclosure dividers 7, which are integrally provided on the bottom plate part with a prescribed gap between them; an enclosure 2, comprising a rotating bracket 6 which is interposed between the enclosure dividers and is supported freely rotatably by the bearing part; a photographic part 12, which is provided on the rotating bracket and is provided with a bearing part on an x-EL axis and is supported freely rotatable about this shaft; an incidence optical path 50a, formed along the AZ axis; and reflection optical paths 50b to 50e via which the light introduced to the incidence optical path is reflected along an EL axis through the device base and one enclosure divider and is reflected toward the photographic part via the x-EL axis.
