When the left shock detection unit 200a detects an impact, the corresponding reflection plate release unit is operated to develop the reflection plates 100a, 100b, 100c, and 100d.

After the reflection plate is developed, the controller 300 applies an operation signal to the image detector 610 of the image sensor 600 to obtain image information of the corresponding area (S500). The acquired image information is transferred from the image sensor 610 of the image sensing unit 600 to the storage unit 700 through the control unit 300 and stored therein (S600).
