摘要：
A leaf-type clock driven by a intermittent and segmental rotation by using so called Geneva-gear mechanism to cause turning-over of the time- and minute-indicating leaves is disclosed. This leaf-type clock has the advantages that number of the leaves may be reduced, and that the time accuracy is improved, and further that small-sized clock can be designed.
