That is, the plurality of coils 1141b, 1143b, and 1145b are provided on the main board 1070 , and the main board 1070 is mounted on the housing 1010 . Here, in the drawings, the main board 1070 is an example in which the coil for the reflection module 1100 and the coil for the lens module 1200 are all mounted as an integral body, but the main board 1070 is the reflection module ( The coil for 1100 and the coil for the lens module 1200 may be separately provided in two or more substrates to be mounted respectively.

As shown in the figure, when rotating about the first axis (X axis), the second ball bearing 1133 aligned with respect to the second axis (Y axis) cannot move while being fitted in the seating groove. This is because, when rotating based on the second axis (Y axis), the first ball bearing 1131 aligned with respect to the first axis (X axis) has a structure that cannot be moved while being fitted in the seating groove.

The light whose path is changed by the reflection module 1100 is incident to the lens module 1200 .
