When the driving unit 150 is installed in the main body 110, the main cover 115 is coupled to the main body 110 so as to shield the opening (unmarked) Some of the components of the driving unit 150 may be prevented from being exposed to the outside to prevent damage and breakage. When maintenance of the drive unit 150 is required, the maintenance of the drive unit 150 can be easily performed only by detaching the main cover 115 from the main body 110. [

The propeller units 130 are spaced apart from each other along the circumferential direction of the main body 110 and are operated by a control unit (not shown) that receives an operation signal transmitted from a user, 110) to propel and propel it. As described above, since four propeller coupling portions 111 are formed in the main body 110, four propeller units 130 are also provided.

Each of the propeller units 130 includes a connecting arm 131, a driving motor 133, and a propeller 135. The connection arm 131 connects the driving motor 133 and the propeller 135 to the main body 110 and is connected to the main body 110 so as to be drawn into the main body 110, A part of which is coupled to the main body 110. More specifically, a part of the connecting arm 131 is inserted and coupled to the propeller coupling portion 111 formed in the main body 110, and the coupling arm 131 slides back and forth horizontally along the propeller coupling portion 111 .

Referring to FIG. 2, in the present embodiment, the connecting arm 131 is formed in a rectangular plate shape, which is elongated along the longitudinal direction as an example. A connection arm guide 131a extending along the longitudinal direction of the connection arm 131 is formed on the connection arm 131. Although not shown in the drawing, the propeller coupling portion 111 is formed with a guide projection 131a which is inserted into the coupling arm guide 131a when the coupling arm 131 is inserted into the propeller coupling portion 111, (Not shown) is formed. The connecting arm 131a inserted into the guide protrusion (not shown) is guided by the guide protrusion (not shown) so that the connecting arm 131 is inserted into the propeller coupling part 111, And is reciprocally slide-moved so as to be drawn out from the propeller coupling portion 111. [

2, the driving motor 133 is installed at the front end of the connecting arm 131, and the propeller 135 is coupled to the shaft of the driving motor 133. The propeller 135 is rotated by the rotational driving force provided by the driving motor 133 to generate propulsive force to fly the main body 110 and fly. Although not shown in the drawing, the driving motor 133 is electrically connected to a control unit (not shown), and the control unit (not shown) receiving the operation signal transmitted from the user operates the driving motor 133, The propeller 135 may be rotated.

The user can illustratively transmit an operation signal using a remote controller (not shown), and the control unit (not shown) is provided with a receiving unit (not shown). The remote controller (not shown) and the controller (not shown) are connected to each other by wireless communication so that the receiving unit (not shown) of the controller (not shown) receives an operation signal transmitted from the remote controller . The communication method of the remote controller (not shown) and the controller (not shown) may be implemented by a known technique of various known embodiments.

The drive unit 150 is provided to reciprocally slide the propeller units 130. For example, all of the propeller units 130 may be reciprocally slide-moved simultaneously, or at least one pair of the propeller units 130 may be reciprocally slidably moved. In particular, one pair or a plurality of pairs of the propeller units 130 and the main body 110 are slidable in the setting direction. Also, the posture of the main body 110 may be controlled by adjusting a relative position between one pair or a plurality of pairs of the propeller units 130 and the main body 110.

The drive unit 150 includes a disk plate 153 and link bars 155, as shown in FIG. The disc plate 153 is disposed inside the main body 110 and connected to the motor 151 so that the disc plate 153 is rotated clockwise and counterclockwise by a driving force provided by the motor 151. [ One end of the link bar 155 is hinged to the disk plate 153 and the other end is hinged to the connection arm 131. The link bars 155 are provided corresponding to the number of the propeller units 130 so that each of the link bars 155 connects each of the connection arms 131 with the disk plate 153. Accordingly, the plate units 130 are simultaneously reciprocally slide-moved.

The link bar 155 converts the rotational motion of the disk plate 153 rotated by the motor 151 into a rectilinear motion and reciprocally slides the connecting arm 131 connected to the link bar 153 . That is, when the disc plate 153 is rotated in either the clockwise or counterclockwise direction by the motor 151, one side of the link bar 155, which is hinged to the disc plate 153, And rotates along the plate 153, and the other side of the link bar 155 is reversed. The connecting arm 131 hingedly connected to the other side of the link bar 155 is inserted into the inside of the propeller coupling portion 111.

On the other hand, when the disc plate 153 is rotated in the clockwise or counterclockwise direction by the motor 151, one side of the link bar 155, which is hinged to the disc plate 153, And rotates along the plate 153, and the other side of the link bar 155 is advanced. Therefore, the connecting arm 131 connected to the other side of the link bar 155 by the hinge connection is drawn out from the propeller coupling part 111. 2, since each of the propeller units 130 is connected to the disk plate 153 by the link bar 155, the propeller units 130 are simultaneously reciprocated Slide is moved.

The connecting arm 131 is reciprocally slid by the driving unit 150 and is drawn into the propeller coupling part 111 or drawn out from the inside of the propeller coupling part 111, So that the separation distance between the rotation axis and the rotation axis of each of the pair of the propeller units 130 can maintain a predetermined maximum separation distance or a predetermined minimum separation distance.

That is, the connection arm 131 is slid by the drive unit 150 and inserted into the propeller coupling portion 111, so that the spacing between the rotation shafts and the rotation shafts of the propeller units facing each other And maintains the predetermined minimum separation interval. Thus, the small flying object 100 capable of shooting the air can reduce the air resistance, so that the flight can be smoother and more free.

The propeller unit 130 slidingly moves the propeller unit 130 by the drive unit 150 so that the propeller unit 130 facing the propeller unit 130 faces the propeller unit 130, And maintains the spacing distance between the rotation axis and the rotation axis of each of the first and second electrodes at the predetermined maximum spacing interval.

That is, when the connection arm 131 is slid by the driving unit 150 and is pulled out from the propeller coupling portion 111, the spacing between the rotary shaft and the rotary shaft of the propeller units 130 facing each other And the predetermined maximum spacing interval is maintained. Accordingly, the small flying object 100, which can be photographed by the aerial photographing, is increased in area in contact with the air during flight, so that the air resistance increases. Therefore, the small flying object 100, Even when taking a picture, it is possible to take a picture stably without shaking.

Meanwhile, the small flying object 100 capable of taking an aerial photograph further includes a supporting means 120. The support means 120 is installed on the lower surface of the main body 110 and is in contact with the ground when the small flying object 100 capable of aerial photographing lands on the ground and the main body 110 is in direct contact with the ground And serves to support the main body 110.
