Abstract

PURPOSE:To shorten the time for wiring and to reduce the cost of assembly by providing lands connecting to lead wires on both flexible printed cables of an arm and packaging an IC connecting to the lands via wiring patterns to the flexible printed cables. CONSTITUTION:The flexible printed cables (FPCs) 13, 14 connected to each other via curved parts 12 are stuck on both the front and rear surfaces of the arm 11 and the lands 15, 16 connecting to the lead wires 8 are provided on these FPCs 13, 14. The lands 15, 16 are connected via the wiring patterns 17 to the IC 3. The lead wires 8 between plural suspensions 6 and the lands 15, 16 corresponding to the respective suspensions 6 are, therefore, shortened. The need for drawing around the lead wires 8 at the time of wiring and the adhesion of the lead wires 8 to the arm 11 is eliminated in this way and the time for wiring is shortened. The cost of assembly is thus reduced.
