PROBLEM TO BE SOLVED: To reduce manufacturing man-hours, as well as to planarize and miniaturize configuration, and to increase output. SOLUTION: A stator 23 of a motor 21 has a printed wiring board 25, and a pair of rotary members 26 and 27 which are contained in a rotor 24 is arranged at both sides in the axial line direction of the printed wiring board 25. The rotary members 26 and 27 are provided with a pair of ring-shaped support members 29 and 30 and ring-shaped permanent magnet pieces 31 and 32 accommodated at sides that are along the axis direction of the support members 29 and 39 and facing opposite to each other for fixing. A plurality of coils 36 are formed on at least one surface facing each of the rotary members 26 and 27 of the printed wiring board 25 through printed wiring. The coils 35 are successively energized, thus forming a rotary magnetic field which advances in the clockwise direction of the printed wiring board 25 and rotating the rotor 24 through the magnetic connection with the permanent magnet pieces 31 and 32. |
