Abstract
A clock includes two dial pieces laterally openably pivoted to a stationary shaft. The dial pieces in a closed position define a single time display face. When a driving motor is started at any set time, two gears with eccentric cams are rotated in opposite directions; as a result, the dial pieces with cam followers held in contact with the eccentric cams are shifted in laterally opposite directions to take an open position, so that a gimmick normally hidden by the dial pieces in the closed position is exhibited. A spring is attached to the stationary shaft to moderately urge the dial pieces in the direction of opening thereof, or a spring is provided to urge the dial pieces in the direction of opening thereof via two pins provided on the eccentric cams in accord with the center lines thereof, whereby the operation of the dial pieces is attained uniformly irrespective of whether they are opened or closed.
