Problems solved by technology

However, when the user adjusts the lens 170, it is usually impossible to know whether the lens 170 is located at a reference position.
For example, the user usually cannot know whether the lens 170 is located at the midpoint of the movement stroke along the first axis A1 and whether it is located at the midpoint of the movement stroke along the second axis A2.
