Title: Power generation watch with rotary weight
Inventor: NAGAO SHOICHI
IPC: G04C3/14
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To improve the characteristics of a watch coil and a generation coil and small-sizing and thinning by forming a generation coil thinner and longer than the clock coil and arranging it overlapping in plane at least a part of clock circuit. SOLUTION: A generation coil 29 is formed long in total length and thin in radial direction. By this, necessary turns are ensured without thinning the wire diameter, the radial dimension of whole coil can be made thin, the total length of the coil wire becomes shorter as a result and the impedance becomes small. Thus, the gear of a power generation rotor transmission wheel 25 and generation coil 29 are overlapped, gear outer diameter can be increased and an acceleration ratio sufficient for power generation can be ensured. Similarly, a part of clock circuit can be overlapped in plane to the generation coil 29 with relatively wide area and so this configuration is advantageous for plane layout in the case of small absolute area.
