  • Patent number: 9244435
    Abstract: A timepiece, which includes an ornamental body; a drive mechanism that moves the ornamental body; an output portion that outputs a sound; and a control portion that performs movement control for outputting a piece of theme music and moving the ornamental body from an initial position. The control portion further performs return control for outputting a piece of ending music and moving the ornamental body to the initial position after the movement control is finished. Under the return control, the outputted and selected pieces of ending music have different lengths depending on whether or not a position of the ornamental body is in front of a reference position. It is thus possible to design the movement pattern of the ornamental body under the movement control, without consideration of the stop positions of the ornamental body at the end of the movement control period; thereby, allowing for a wide variety of appearances for the timepiece.

  • Patent number: 8339902
    Abstract: A clockwork mechanism includes: a supporting member; a movable member including an engagement hole and movably supported by the supporting member; a drive pin engaging the engagement hole, including a flange portion for preventing the drive pin from disengaging from the engagement hole, and revolving to move the movable member; a biasing member provided in the movable member to partially overlap the engagement hole; and an abutment member abutting the movable member to restrict the movement of the movable member. The flange portion overlaps or does not overlap the biasing member depending on a revolving position of the drive pin. When the movable member abuts the abutment member, the drive pin pushes the biasing member and the movable member is biased toward the abutment member by the biasing member. When the flange portion does not overlap the biasing member, the drive pin moves the movable member to push the biasing member, allowing the drive pin to disengage from the engagement hole.

  • Patent number: 7339855
    Abstract: A mechanical timepiece has an ornamental portion and a plurality of movable units operable to expose and hide the ornamental portion. Each of the movable units includes a divisional segment for exposing and hiding the ornamental portion by inward and outward movement, a holding plate configured to hold the divisional segment in a movable manner so as to move the divisional segment in inward and outward directions, and an attachment structure for attaching the divisional segment to the holding plate. The attachment structure is formed integrally with at least one of the holding plate and the divisional segment. The attachment structure includes engagement portions projecting from both sides of the holding plate and a pair of holder members formed on a surface of the divisional segment so as to have an L-shaped cross-section with their tip portions being opposed to each other.
