发明名称 Timepiece display apparatus, movement, and timepiece
摘要 A timepiece display apparatus causes a day hand to move reciprocally by means of center wheel, driven day wheel, cam, lever, and rack. These wheels, cam, lever, and rack can be easily arranged to fit the available space on the main plate of the movement, and the construction of the display apparatus can thus be simplified. Furthermore, locating the cam between the rotary shaft and rack of the lever portion enables arranging a plurality of parts more compactly than if the cam is disposed to a different location, and affords a simple assembly.
