Abstract:
A thermoelectrically operated timepiece using electric power generated by a thermoelectric generator means as an energy source, the timepiece comprising:heat input means for absorbing heat from a human body when in contact with the human body;thermoelectric generator means for producing an output voltage in response to a temperature difference thereacross and having a first portion which receives heat absorbed by the heat input means and a second portion which is cooled by atmospheric temperature conveyed thereto by a case of the timepiece;a first thermally conductive elastic member for conducting heat absorbed by the heat input means to the first portion of the thermoelectric generator means (52);heat output means formed on the case of the timepiece and being in direct contact with the dial of the timepiece for cooling the second portion of the thermoelectric generator means; anda second thermally conductive member in direct contact with the second portion of the thermoelectric generator means, the dial of the tiempiece, and the heat output means for conducting heat between the second portoin of the thermoelectric generator means and the heat output means, so that the heat output means and the heat input means are spaced widely from each other within the timepiece.
