<p>PURPOSE:To make necessary electric power a little, by a method wherein two levers are supported turnably by a supporting shaft provided on a main body, end parts of the levers are connected with levers supported bendably, and a yoke equipped with an excitation coil is fixed to one side ends of the levers. CONSTITUTION:Levers 1, 2 and a gear 9 are supported turnably by a supporting shaft 9a provided on a main body. Levers 3, 4 supporting respective eccentric rotary wheels 10, 11 turnably and supported bendably on end parts of the levers 1, 2 by a connecting shaft 4a are connected with supporting shafts 10a, 11a of the levers 1, 2 and a yoke equipped with an excitation coil 7 is fixed to an end part of the lever 3. With this construction, even if a spring 1a stretched between the levers 1, 2 is a strong one, a magnet 6 can be done with a tiny one by keeping an included angle between the levers 3, 4 at about 180 deg.. Electric power, therefore, electrifying the exciting coil 7 can be done with a little power.</p> |
