Patent ID: 7480213

Claim:
A mechanical timepiece comprising: a plurality of divisional segments divided in a movable manner; a driving source operable to produce a driving rotation for moving and rotating said divisional segments; an ornamental portion to be exposed by outward movement of said divisional segments; and a plurality of driving mechanisms operable to move the corresponding divisional segments and rotate them about their axes so as to change an exposure state of said ornamental portion by using the driving rotation transmitted from said driving source wherein each of said plurality of driving mechanisms includes: a rotatable member rotating by the said driving source, a rotatable stage rotating in cooperation with said rotatable member rotating beyond a predetermined range, and a slide plate to which the corresponding divisional segment is attached, said slide plate being slidably supported by said rotatable stage, and said slide plate being configured to slide in cooperation with said rotatable member rotating within the predetermined range and to rotate in cooperation with said rotatable member rotating beyond the predetermined range, wherein when said slide plate slides, said slide plate does not rotate, and when said slide plate rotates, said slide plate does not slide.
