PURPOSE:To prevent the disconnection of a lead wire by providing at least one acicular lead wire inserted in a case and in electric contact with a fluid conductive material and another lead wire connected from the fluid conductive material to a drive circuit. CONSTITUTION:In energizing a lead wire 19 from a drive circuit C, an input is given to a mobile coil 12 via a fluid conductive material 18 in a case 17 and the acicular lead wire 16, a mobile coil 12 is vibrated vertically as shown in the arrow A to reciprocate the filter frame 8 vertically and a filter applies required color separation. In this case, the tip of the acicular lead wire 16 is immersed in the fluid conductive material 18 and moved rapidly vertically, and since the tip of the acicular lead wire 16 always exists in the fluid conductive material 18, the power from the drive circuit C to the mobile coil 12 is not intermitted. Thus, no deflection nor stress concentration is applied to the feeding member such as the lead wires 16, 19 and a fault such as the disconnection of wire is not caused.
