Abstract
PURPOSE:To obtain a click mechanism which applies no load to a step motor as a reliable indexing is carried out, by employing a solar wheel and planetary wheel to a hand correcting mechanism. CONSTITUTION:With a crown pulled in 2-step, a teeth part 64a of a hourglass wheel engages a first small iron wheel 57 to permit a hand correcting mechanism to move, which results in enabling the rotation of a solar wheel 53. A step motor stops moving and a second had suspends moving at an arbitrary position, whereby planetary wheels 51 and 50, attached to a second hand wheel, stop moving at an arbitray position. With the solar wheel 53 and a minute wheel still engaging each other, the minute wheel turns by a full tooth through the rotation of the solar wheel 53 by a full tooth. Then, a hand correcting mechanism performs a clicking action through the working of a first arm part 72a of an index spring 72 for indexing a first star wheel 71 and an indexing lever 58 engaging an index wheel 54.
