    • A time piece is switched from the before-noon display to after-noon display and vice versa. A cam (26) is rotated by an hour wheel (10) and an intermediate wheel (12) one revolution per day. In the morning, a lever (30) is in contact with the major-axis side of the cam (26), and at noon, the lever (3) reaches a changing point between the major-axis part of the cam (26) and the minor-axis part. When the cam (26) further rotates in the direction indicated by arrow (FB), the lever (30) is instantaneously displaced by a spring (34) from the major-axis position of the cam (26) to the minor-axis position. The displacement of the lever (30) is transmitted to a movable dial plate (36) by means of a tooth section (31) and switching groove (39) provided at the front end of the lever (30) and the dial plate (36) is rotated by a prescribed angle in the direction indicated by arrow (FC). Therefore, the before-noon display is instantaneously switched to the after-noon display.
    • 时间片从中午前显示切换到中午后显示,反之亦然。 凸轮(26)通过时轮(10)和中间轮(12)每天旋转1圈。 早上,杠杆(30)与凸轮(26)的长轴侧接触,中午,杠杆(3)到达凸轮(26)的长轴部分之间的变化点, 和短轴部分。 当凸轮(26)进一步沿箭头(FB)所示的方向旋转时,杆(30)被弹簧(34)从凸轮(26)的长轴位置瞬时移位到短轴位置 。 杆(30)的位移通过设置在杆(30)的前端和拨盘(36)的齿部(31)和切换槽(39)传递到可动表盘(36) )沿箭头(FC)所示的方向旋转规定的角度。 因此,中午前显示瞬时切换到中午后显示。
