  • Patent number: 11474481
    Abstract: Provided is a movement enabling easily providing an indicator position detection mechanism in a movement enabling changing the locations of an indicator by changing the configuration of a wheel train. The movement includes an indicator wheel to which an indicator is attached; a motor that drives the indicator wheel; a detection wheel train used to detect a position of the indicator; and a main plate to which the indicator wheel, the motor, and the detection wheel train are disposed. The main plate is configured to enable selectively disposing the indicator wheel to a first position or a second position that is different from the first position. The detection wheel train is disposed to the same position whether the indicator wheel is disposed to the first position or the second position.

  • Publication number: 20120188855
    Abstract: A timepiece according to a first aspect of the invention has a fan-shaped display unit including a display wheel that can rotate, a stepping motor that rotationally drives the display wheel in both forward and reverse directions, a reverse stop that limits reverse rotation of the display wheel, and an indication means that is attached to the display wheel; and a control unit that applies pulses to the stepping motor. The position of the reverse stop is set so that the orientation of one polar axis of the rotor of the stepping motor when the display wheel is stopped by the reverse stop at the reverse stop is within ±360°/(number of magnetic poles of rotor*2) from the static stable position of the polar axis. After stopping at the reverse stop, the polarity of the first pulse applied to the stepping motor by the control unit is constant.
