<p>PROBLEM TO BE SOLVED: To facilitate the connecting of a power source in assembling by providing plural suspenders whose one ends are fixed to a holder and connected to the power source and whose other ends are connected to lead wires wound around first and second protrusions to impart control signals to a converging coil and a tracking coil. SOLUTION: After a tracking coil 14 and a converging coil 15 are respectively wound around first and second movable supports 12, 13 and lead wires 14a, 15a of the respective coils are wound around first and second protrusions 12a, 13a, the first and second movable supports 12, 13 are adhered with each other. Then, after one ends of elastic suspenders 16 are fixed to a holder 10 fixed to a base 100, other ends of the suspenders 16 are soldered to the lead wires 14a, 15a wound around the first and second protrusions 12a, 13a. Consequently, a current from power source terminals 10a-10d can be supplied to the tracking coil 14 and the converging coil 15 via the elastic suspenders 16. Moreover, the first and second movable supports 12, 13 are elastically supported with the elastic suspenders 16 and they are made to be in horizontally and vertically movable states with respect to the holder 10.</p> |
