Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a geared stepping motor that saves on a space while achieving size reduction, and is suitable for the promotion of the size reduction of an apparatus that is scheduled to be assembled. SOLUTION: Accurate rotational angle control becomes available without the need for utilizing a rotational angle sensor such as a photosensor by employing a steeping motor part 11. A space is saved on while achieving the size reduction by placing the stepping motor part 11 and a planetary gear reduction part 31 in a box 30 in parallel with each other, and the size reduction of the mobile communication apparatus or the like is promoted. By connecting a first flat gear 50 arranged at a rotating shaft 16 of the stepping motor part 11 and a second gear 51 arranged at a rotating shaft 32a of the planetary gear reduction part 31 by a reduction two-stage flat gear 53, gear reduction also becomes available at a part other than the planetary gear reduction part 31. The number of reduction stages, or a reduction rate in the planetary gear reduction part is reduced, thus contributing to the size reduction. COPYRIGHT: (C)2007,JPO&INPIT |
