    摘要： An alarm mechanism for an alarm clock has an alarm hand and an hour hand mounted coaxially with respect to each other, and slideably contacting hub portions of the alarm hand and the hour hand are formed with cam grooves and cam pawls respectively. The cam grooves and cam pawls are positioned with the same positional relationship with respect to the hub portions of the alarm hand and hour hand so that at a preselected alarm time, the cam grooves and cam pawls cooperatingly engage one another to thereby actuate a mechanism to sound the alarm of the alarm clock. In attaching the hands to the clock during assembly, it is possible to attach the alarm hand and the hour hand onto respective shafts at any random angular position without having to pay special attention to the respective positional relationships of the two hands. The hands can be formed in multiple parts and molded together.

    摘要翻译： 用于闹钟的闹钟机构具有相对于彼此同轴的报警手和小时手，并且分别与报警手和时针的轮毂部分可滑动接触地形成有凸轮槽和凸轮爪。 凸轮槽和凸轮爪相对于报警手和时针的轮毂部分具有相同的位置关系，使得在预选的报警时间，凸轮槽和凸轮爪彼此协作地接合，从而致动机构 发出闹钟的闹钟。 在组装时将手连接到时钟，可以在任何随意的角度位置将报警手和时针附着到相应的轴上，而不必特别注意两只手的各自的位置关系。 手可以形成多个部分并模制在一起。

    摘要： A rotary time-indicating plate-type digital display device comprises a rotary minute drum carrying a set of minute-indicating plates and a rotary hour drum carrying a set of hour-indicating plates. A drive system effects continuous rotation of the minute drum to individually turn over successive minute-indicating plates to display the time in minutes and effects intermittent rotation of the hour drum to individually turn over successive hour-indicating plates to display the time in hours. A lower system coacts with the minute and hour drums to effect synchronous turning over of the minute-indicating plate which indicates the 59th minute and each successive hour-indicating plate. An adjusting mechanism is disposed adjacent the minute drum for enabling adjustment of both the minute and hour drums to set the time displayed by the indicating plates.

    摘要翻译： 旋转时间指示板型数字显示装置包括：携带一组微小指示盘的旋转微型滚筒和携带一组小时指示盘的旋转小时滚筒。 驱动系统实现分钟滚筒的连续旋转，以单独翻转连续的分钟指示板，以分钟显示时间，并实现小时滚筒的间歇旋转，以单独翻转连续的小时指示板以显示时间（小时）。 下部系统与分钟和小时鼓共同作用以实现指示第59分钟和每个连续的小时指示板的分钟指示板的同步翻转。 调节机构设置在分钟鼓附近，以便能够调整分钟和小时的滚筒以设定指示板所显示的时间。
