Based on the design of the supporting elements 1-140, the first movable assembly 1-20 is supported by the supporting elements 1-140 and is suspended in the outer frame 1-102, so that when the first driving assembly 1-30 drives the circuit member body 1-1141 and the photosensitive element 1-122 to move along the XY plane, the circuit member body 1-1141 does not collide with the base plate 1-120.
In other embodiments, the first driving assembly 1-30 is disposed between the first movable assembly 1-20 and the second movable assembly 1-40, and the supporting elements 1-140 are omitted. Thus, one end (the first end portion) of the first segment 1-SG1 and the connecting portion 1-SCP (the second end portion) are at the same level in the main axis. That is, the first end portion and the second end portion are on the same plane.
