PURPOSE:To reduce the number of printed wiring boards to one by arranging a driving integrated circuit and a control means for feeding pulses to the driving integrated circuit on the printed wiring board. CONSTITUTION:Wiring of a pulse motor 11 is connected with a PC(printed wiring) board 13 at the end section 12 thereof, then it is connected through the PC board 13 with a lead wire 14. A driving IC (integrated circuit) 15 for driving the pulse motor 11 and a control IC 31 as a controlling circuit therefor are arranged on the PC board 13. Since the IC for driving the pulse motor and the control IC therefore are arranged integrally on the PC board for connecting the winding of the pulse motor with the lead wire, the number of the PC board can be reduced. |
