摘要

The device has a printed circuit board (15) formed for controlling a control unit to activate an objective lens. Another printed circuit board (16) is formed for providing instructions to the former board, so that the lens is activated. A flexible printed circuit board (17) is connected with the boards (15, 16) for establishing an electrical connection between the boards (15, 16), such that the board (17) is twisted approximately in its center.
