These four dampers 143 are located on a virtual line connecting the pair of steering wheels W1 and the pair of driving wheels W2 in an oblique direction so that they are transmitted by four wheels W1 and W2 Thereby absorbing the vibration independently.

The damper 143 includes a first supporting end 144 fixed to a corner side of the first table 141; A second supporting end 145 for supporting a corner side of the second table 142; A lift box 146 fixed to the second support stage 145 and vertically coupled to the first support stage 144; A spring 147 installed between the inner ceiling of the lifting box 146 and the first supporting end 144; An electromagnet 148 supported on the first support end 144 inside the spring 147; And a magnet 149 fixed to the ceiling of the lifting box 146 on the upper side of the electromagnet 148 inside the spring 147.

A step 144a is formed at the edge of the first support end 144 and a collapse 146a is formed at the lower end of the lift box 146 to be hooked on the step 144a. The lift box 146 is elevated with respect to the first support stage 144 but not separated.

A ball portion 145a is formed on the upper side of the second support end 145 and a groove portion 142a is formed on the second table 142 to support the ball portion 145a. When the lifting and lowering box 146 is lifted and lowered in the process of independently absorbing the vibration of each of the four dampers 143, the ball portion 145a of the second supporting end 145, which is supported by each of the winching boxes 146, Can be moved forward, backward, leftward, and rightward in the groove portion 142a of the second table 142. As a result, each of the four corners of the second table 142 is independently absorbed by vibration and is applied through the conveying vehicle 10 Effectively absorb vibration in an unspecified direction.

The spring 147 is provided between the inner ceiling of the lifting box 146 and the first supporting end 144 to elastically support the lifting box 146 against the first supporting end 144.

The magnet 149 of the ceiling of the inner side of the lift box 146 is kept spaced apart from the core 148b of the electromagnet 148 by the elastic force of the spring 147, The fine vibration is absorbed by the spring 147 and is not transmitted to the digital camera C, thereby enabling high-quality VR imaging.

(b) In the case of a smooth environment in which the ground of the place where the VR image is photographed does not generate vibration,

A mode is selected in which a power source having a polarity in which attraction is generated in the electromagnet coil 148a of the vibration absorption portion 140 is selected. In this case, the magnet 149 overcomes the elastic force of the spring 147 and is attached to the core 148b of the electromagnet, and the damper 143 loses its damping ability.

(c) In an environment where the floor of the place where the VR image is photographed is rough and a lot of vibration is generated,

A mode in which a repulsive force is generated by applying a power of an opposite polarity to the coil 148a of the electromagnet is selected. In this case, a repulsive force by a repulsive force and a repulsive force by an elastic force of the spring 147 are added between the magnet 140 and the core 148b of the electromagnet, and the damper 143 has a strong damping capability, It is possible to absorb a strong vibration transmitted to the vehicle 10.

As described above, in the present invention, the digital camera absorbs the vibration transmitted through the conveying vehicle 10 during the photographing of the VR image while the digital camera moves, so that the digital camera can photograph the high-quality VR panoramic image. Particularly, since the damping capacity of the damper 143 can be varied according to the degree of roughness of the ground, the conveying vehicle 10 can effectively absorb the vibration during the movement in any ground environment.
