Abstract
A timepiece including two base plates opposite each other and defining a space therebetween, and having a gear train and an electro-mechanical converter for driving the gear train and both disposed in the space between the two base plates. The converter includes a stator comprised of a platelike member defining an intermediate plate portion positioned in the space between the two base plates. The intermediate plate portion supports gear train components and is isolated magnetically from the rest of the stator.
Claims6
In a timepiece, the combination comprising:
- two base plates opposite each other and defining a space therebetween;
- a gear train comprised of gear wheels and disposed in the space between said base plates;
- and electro-mechanical converter means responsive to electrical signals for driving said gear train and disposed in the space between said base plates, wherein said converter means is comprised of a stator, a rotor positioned opposite said stator, and means for magnetizing said stator to effect rotation of said rotor, and wherein said stator is comprised of a plate-like member defining an intermediate plate portion positioned in the space between said base plate and supporting at least a gear wheel of said gear train.
In a timepiece, the combination comprising:
- two base plates opposite each other and defining a space therebetween;
- a gear train comprised of gear wheels mounted for rotation on arbors and bearings and disposed in the space between said base plates;
- and electro-mechanical converter means responsive to electrical signals for driving said gear train and disposed in the space between said base plates, wherein said converter means is comprised of a stator, a rotor positioned opposite said stator, and means for magnetizing said stator to effect rotation of said rotor, and wherein said stator is comprised of a plate-like member defining an intermediate plate portion positioned in the space between said base plates and supporting a bearing of a gear train gear wheel arbor.
