Abstract
A doll action mechanism which comprises a plurality of movable members for a doll or the like, a plurality of rotational drive sources arranged outside of the doll or the like, and a plurality of drive shafts individually connected to the rotational drive sources and the movable members and arranged on a common axis. Further, in another construction, a doll action mechanism has a plurality of movable members and a plurality of rotational drive sources individually coupled to the movable members. The improvement comprises a first rotational drive source for imparting an initial motion, a first movable member enabled to move by the first rotational drive source, a second movable member connected to the first movable member through a planetary gear mechanism, and a second rotational drive source for driving the second movable member.
Claims5
In a doll action mechanism comprising:
- a first rotational drive source for imparting an initial motion;
- a first movable member enabled to move by said first rotational drive source;
- a first rotational shaft for connecting said first rotational drive source with said first movable member;
- a planetary gear mechanism having a sun gear disposed on a rotational axis of said first movable member and a planetary gear rotating around the sun gear with said first movable member;
- a second movable member connected with said planetary gear mechanism;
- a second rotational drive source for rotating said sun gear;
- a second rotational shaft for connecting said second rotational drive source with said sun gear;
- said second rotational shaft being disposed coaxially with said first rotational shaft;
- and
- control means for controlling said first rotational drive source and said second rotational drive source independently.
