Nonlinear movement and tilt angle control structure of an image capture device inside a light box includes a nonlinear motion set, a rotation set, a cartridge and a compartment. The nonlinear motion set uses dual guiding rails or a single guiding rail to drive the image capture device from top and side directions. The rotation set rotates the image capture device. The cartridge carries the rotation set and is driven by the nonlinear motion set to perform the nonlinear motion. And, the compartment is configured inside the rotation set to ride and fasten the image capture device.
