PURPOSE:To obtain a low-cost liquid crystal watch by insulating a coil winding core or a coil winding core and a york from a base plate. CONSTITUTION:A completed coil 24 consists of a coil winding core 14, a terminal board 15, a winding frame 17, and a coil 18. The coil 24 is incorporated into a york 13 by inserting a tube 12 into fixing holes 14c, 14d drilled into the winding core 14. Since an insulating part 16a is formed on the upper and lower surfaces of the core 14 at the fixing hole 14C side, the core 14 is insulated from other parts even if coupled with a screw 22. Namely the core 14 is insulated from a base plate 11 and reference voltage is not applied to the core 14, so that when the coil 18 is directly wound around a winding part 14e of the core 14, battery capacity is not reduced because current does not flow into a driving circuit differently from conventional methods. |
